Your LBD (little black dress) is about to be joined in your closet by a SWD (smart wearable device). The worlds of electronics and textiles are becoming interwoven and the results are going to profoundly impact your health. Here’s what you need to know about e-textiles and smart fabrics and a preview of the clothes, shoes, and accessories  that may soon find their way into your closet.

E-Fashionista Vocabulary
Just when you thought you’d finally gotten a handle on terms like ruching, GORE-TEX, and tulle, along comes a whole new fashion lexicon. Forget about SmartWool. We now have smart fabrics and smart clothes. And intelligent textiles, interactive textiles, interactive clothing, and wearable computing. And e-fabrics, e-textiles, e-fibers, and e-broidery.

E-textile is short for electronic- or electro-  textile. E-textiles are essentially fabrics with electronics and other components that are embedded in, or intrinsic to, the fabric such that the fabric maintains its key properties, like draping. (Shown, conductive silver plated nylon thread)

Smart fabrics are generally defined as, well, smart. This means a fabric can not only sense the environment, but also react to it. Scenarios include a fabric that warms you when you’re cold, cleans itself when it’s dirty (hooray!), lights up to ensure you’re visible when it’s dark, and automatically stiffens to protect you when you’re falling. Smart clothes could monitor your fitness parameters as you train and give you advice to modify your workout, during your workout. And of course smart clothes would recharge your mobile device while it was tucked in your pocket.

Smart clothes and e-textiles offer a second skin to help you understand what goes on under your real skin. They enable you to wear sensors comfortably and unobtrusively to track your physiological signals and your surrounding environmental conditions in real time – anytime, anywhere. They are going to influence the health of patients, the training of athletes, and the safety of fire fighters. And perhaps most significantly, they are going to create an entirely new paradigm of wear, share, and compare.

Form follows function and function follows form
Sensors that detect physiological signals may be embedded or integrated directly into a textile (such as part of a yarn that is woven or knitted into the fabric) or they may be applied on top of the fabric, such as in an ink. Since the sensors are part of the garment, they are usually in direct contact with your skin.

The sensors can detect an amazing range of physiological stimuli from you and your surrounding environment. These include mechanical, thermal, chemical, electrical, optical, and magnetic signals. Once the sensors detect the signal, it’s collected, processed, stored and transmitted.

The potential of e-textiles and smart clothes is best demonstrated by applications in two key areas: health/medical and sports/professional performance and safety. These niches tend to be where cutting-edge development occurs and thus are good indicators of products and technology that may move mainstream (for further discussion on this, see Self-tracking, Sensors, and mHealth: Trends and Opportunities). Here are examples of just a few of the many really cool products that are in various stages of commercialization and development.

Under pressure: Under Armour E39 electronic compression shirt
The Under Armour E39 shirt, developed through a partnership with Zephyr Technology  (which makes the BioHarness), features a removable electronic monitor, or “bug.” The bug is a combined sensor pack, processor, and hard drive that plugs into the shirt. The sensor measures heart rate, breathing rate, skin surface temperature, and triaxial (3 axes – X, Y, Z – thus three dimensional) accelerometry. Sensor data can be sent via Bluetooth to smart phones and laptops for viewing by coaches and friends. The E39 shirt debuted at the NFL Scouting Combine in February, 2011 and is expected to be available to the public in 2012. (photo from Under Armour)

A real kick: The adidas adizero f50 powered by miCoach
Marketed as the “football boot with a brain,” the adidas adizero f50 soccer shoe contains a space in the outsole (bottom) to tuck a miCoach Speed Cell. This tracking device captures performance metrics such as speed, maximum speed, number of sprints, distance, steps and stride rates. The data are stored and can be wirelessly uploaded to a PC, Mac or  smart phone so you can share and compare your stats with friends or adidas professional players. The shoes and speed cell/USB adaptor are sold separately or as a bundle (available in November [ADDED NOTE: became available Nov 11]). The sensor device has been designed to be compatible with other adidas footwear. Expect a related miCoach online football (soccer) video game in 2012. (photo courtesy of adidas)

Reebok and mc10: Flexible electronics
Reebok is collaborating with mc10 to create intelligent sports equipment and apparel. Based on research by John Rogers of UIUC and George Whitesides of Harvard, mc10 develops thin “conformal” electronics that can bend and stretch and that can be imbedded into materials such as paper, fabric, latex, and leather. This is definitely a partnership that bears close, um, tracking.

Smarty pants: Printing biometric sensors on underwear
What better place to put sensors than the elastic band of your underwear? This location enables sensors to be in direct and continuous contact with the skin. Researchers have screen-printed amperometric carbon sensor arrays directly onto the elastic band of underwear. The sensors survive repetitive stretching, pulling, and folding. The sensors can measure hydrogen peroxide and NADH, and could potentially monitor chemicals found in sweat through dehydrogenase- and oxidase-based enzyme sensors (for example, ethanol and lactate). Applications include healthcare, sport, and military monitoring. (Image from the Royal Society of Chemistry)

PSYCHE Project: Updating the mood ring
The PSYCHE (Personalized monitoring SYstems for Care in mental HEalth) project aims to develop a cost-effective, continuous portable monitoring system for patients affected by mood disorders, such as bipolar illness. The goals of the project are to empower patients to proactively monitor their mood status in order to predict, detect and manage critical events and health issues; to improve patient-physician interaction; and to alert physicians in case of depressive or manic episodes. This system is currently being implemented and validated technically, functionally, and clinically.

Potential measurements include:

• Physiological: heart rate (electrocardiogram, ECG), respiratory rate, movement, galvanic skin resistance, brain wave activity (electroencephalogram, EEG), eye activity (electrooculogram, EOG), blood pressure, body temperature
• Biochemical: levels of prescribed drugs such as lithium; glucose, cholesterol, triglycerides and other indicators of metabolic disorders that can develop as a side effect of medication use
• Behavioral: obtained from correlating biochemical measures, voice analysis, and a behavioral index

Potential features include data that are collected along with “subjective annotations” and then integrated into an electronic health record (EHR) with information such as medication; measurement of both thoracic and abdominal respiration through textile sensors, thus potentially offering a mechanism for biofeedback training exercises; and night monitoring of heart rate, breathing rate and ambient conditions (temperature, light, noise) to deduce sleep status, which could be combined with sensorized bed sheets.

Sensors that fit like a glove
How do you measure hand function in individuals that have a neurological disorder?  With an instrumented glove. Researchers have developed a glove that measures finger and wrist flexion based on bend sensors that contain a carbon/polymer-based ink whose resistance increases with bending. Finger movements can be measured while the user is performing specific tasks, and even slight changes in fine motor skills can be detected.

Several commercialized, instrumented gloves are already available, mainly for virtual reality and computer gaming:

• CyberGlove II (shown)
• P5 Glove
• The Peregrine glove
• Nintendo Power Glove (vintage video commercial)

A vested interest in congestive heart failure patients and Mount Everest climbers
Leave it to a group of Italian researchers to develop a vest that perfectly marries form and function. The MagIC (Maglietta Interattiva Computerizzata) is a vest with embedded sensors made of conductive fibers to measure heart rate and breathing rate, and an electronic module with a triaxial accelerometer, data storage, and signal transmission. The washable vest comes in several sizes, is specifically tailored to minimize artifacts, and has a front or side opening with Velcro or a zipper so it can be worn by people with impaired movement.

The garment has been validated in several diverse telemedicine applications. In one scenario, patients with congestive heart failure who had recently been discharged from the hospital wore the vest in their homes for a few minutes each day for a month. The data were viewed remotely by a cardiologist. Patients reported that the garment was comfortable and that they felt “safely supervised.” The patients actually requested to continue the monitoring period!

In a more extreme scenario, climbers wore the vest on a Mount Everest expedition. The vest was made of polypropylene instead of cotton, and the position of the electronic module was moved higher up so it didn’t interfere with the climber’s backpack belts. Measurements were collected during the day and during sleep. Again, the vest was comfortable and provided accurate real-life telemonitoring.  (Image from Istituto Auxologico Italiano)

The ProeTEX Project: Fighting fire with wire
The ProeTEX project is a tour de force of sensor technology and usability. The goal is to develop e-textiles for emergency disaster personnel in order to improve their safety.  End-users, such as fire fighters, are part of the project team, and specific operative scenarios were deployed as part of the process to develop several garment prototypes.

T-shirt or inner garment: This assesses the health status of the emergency worker through measurement of physiological parameters. An elastic region contains textile electrodes for measurement of heart rate, as well as a body temperature sensor. Sensors for blood oxygen saturation (SpO2) and sodium (Na+) can also be integrated. A detachable band contains a piezoelectric breathing rate sensor and the electronic modules. Since this garment is in contact with the user’s skin, comfort is considered a key design feature.

Jacket or outer garment (shown): This monitors the user’s activity state and the surrounding environment. There are two triaxial accelerometers. One at the collar detects inactivity and falls to the ground and one at the wrist also detects inactivity. Together they provide a estimation of body inclination. A textile motion sensor located in the elbow region provides redundancy in measuring user movement. A carbon oxide sensor is located in the lapel area, near the user’s mouth and nose. There’s also an external temperature sensor, a heat flux sensor, and a GPS antenna, as well as a visual alarm and acoustic alarm to warn the user of detected dangers. The jacket contains electronics for data storage and transmission.

Boots: At the request of the end users, the boots contain sensors to measure the concentration of toxic gases, like carbon dioxide (CO2), that are heavier than air and accumulate at ground level. The boots also monitor the contact of the foot with the ground, thus tracking the activity of the user.

The data from all the sensors are recorded in a device located in the jacket and transmitted wirelessly to a remote post where all the parameters of the emergency personnel can be monitored in real time.

ProeTEX is one of many Smart Fabrics, Interactive Textile (SFIT) projects funded by the European Commission and conducted by a large consortium of European partners that includes universities, research centers, medical hospitals, and industry. Other projects include MyHeart, BIOTEX, STELLA, and OFSETH.

Sensor Accessories = Sencessories
While there are amazing e-textile garments commercially available and in development, what any true-blue fashionista knows is that accessorizing is what really matters. Forget about watches that resemble a car dashboard duct-taped to your wrist. Companies are now developing sleek sencessories, such as the Jawbone UP (shown), a motion sensing band that tracks your movement  (or your lack of movement) using technology from MotionX.

Imagine sencessories such as cuff links, earrings, a brooch, belt, bracelet, tie bar, pendant, finger ring or toe ring that you can mix and match to monitor your heart rate, breathing rate, blood glucose, calories burned, and ambient air quality.  What sencessory would you most like to sport?

Wear, Share, Compare
E-textiles and smart clothes are going to revolutionize virtual data sharing communities. In the sports world, you’ll be able to compare your data against the data of your drinking buddies and your favorite pro athletes. Polar provided live race data during the Tour de France and Guinness Rugby has put RFID chips into rugby balls and player jerseys. Expect to see more live tracking of pro athletes during major sporting events (see STATS SportVU video for examples), as well as integration and gamification with fantasy sports leagues and video games.

On the medical side of the spectrum, you’ll be able to share your data in real time with your PHR and with health care providers, giving you the ability to leave a hospital early, or even to just leave a hospital room. E-textile data will be shared in existing online communities such as Patients Like Me and Cure Together, and will provide the base for new communities. The data are going to drive new research paradigms and help us better understand the connection between our health and our environment.

Dress for Success
As you can imagine, there are numerous challenges to overcome when designing e-textiles:

• The sensors need to be accurate, reliable, sensitive, specific, low cost, reproducible, have a short analysis time, a high signal to noise ratio (low motion artifacts), and work over a wide range of temperatures.
• The clothes need to maintain their key properties, such as bending, stretching and drapability. They should also be washable, long lasting, light weight, and should be easy to put on and off if they are going to be worn by people with disabilities.

When it comes to health applications, it’s especially important to pause and consider user context. Life is not ‘one-size-fits-all’ and smart clothes shouldn’t be, either. To be successful, e-textile garments will need to:

• be based on need, not driven by technology
• be comfortable and affordable
• be intuitive to use
• be integrated with health care providers and systems as appropriate
• improve the wearer’s quality of life.

This is a very hot field and there will be incredible developments in the future. Watch for:

• sensors that detect not only what goes on under your skin, but also on your skin. Imagine tracking your skin microbiome to better gauge your health status and disease risks
• advances in data analytics to identify trends and anticipate critical events (imagine being able to predict an epileptic seizure or migraine)
• sensor tattoos
• utilizing data for real-time personal biofeedback training, such as stress reduction
• harvesting or scavenging energy from your body to power your smart clothes. Energy sources include your breath, blood flow, body heat, and foot strike during walking.

Research in e-textiles may also lead to new insights in clothing design for individuals with various medical needs that have not yet been recognized, let alone addressed. There is customized clothing for women who have undergone mastectomies, people with an ostomy or stoma, and individuals with Down’s Syndrome. What’s missing? What would you like to see redesigned? And how can we best reinvent the hospital gown?

Clothes are our second skin. They let us express who we are. Our relationship with our clothes will grow even more personal in the future as they not only track our physiological and environmental status, but also react to protect us and serve to connect us.

“Research reveals new secret weapon for Le Tour,” read the press release headline, referring to the Tour de France. “Now there could be a new, completely legal and rather surprising weapon for riders aiming to shave vital seconds off their time – beetroot juice.”

Beetroot juice? Within 24 hours my local bike club forum was buzzing about the news. The research, published in Medicine & Science in Sports & Exercise (June 2011), is the latest in a series of studies on beetroot juice and exercise conducted by Dr. Andy Jones and crew at the University of Exeter (the University put out the press release).

The study found that men who consumed 0.5 liters (~17 ounces) of beetroot juice improved simulated 4 km and 16.1 km cycling time trial performance by 2.8 percent (11 seconds) and 2.7 percent (45 seconds), respectively, as compared to when they completed the rides after drinking a placebo. Power output increased while oxygen consumption was not changed, indicating cycling economy was improved. The participants drank the juice 2.5 hours before completing the rides, which were conducted on stationary bikes.

The nine competitive male cyclists (average age 21 years) who participated in this study were asked to avoid strenuous activity and refrain from caffeine and alcohol consumption prior to coming to the lab to ride. This is standard. But a subsequent step in the protocol is not standard:

“The subjects also abstained from using antibacterial mouthwash and chewing gum during the supplementation periods because these are known to eradicate the oral bacteria that are necessary for the conversion of nitrate to nitrite.”

Huh? It turns out beetroot juice is just the tip of the iceberg for an exciting and rather amazing area of research that also involves bacteria and spit. You’ll be hearing a lot more about this work and its implications for sports performance and health, so it’s worth a closer look.

Why beetroot juice?
Beetroot juice is chock full of inorganic nitrate. The nitrate (NO₃^-) gets converted to nitrite (NO₂^-), which is then converted to nitrogen oxides, such as nitric oxide (NO). Nitric oxide is a powerful signaling molecule that is thought to be responsible for the majority of the physiological benefits. [Nitrate is not the same as nitrite. See  the section on risks below.]

Beetroot juice contains lots of nutrients, including antioxidants and polyphenols. To make sure the effects were due to nitrate, the researchers selectively removed  just the nitrate from the juice. When participants were given this altered juice, they exhibited no improvements in cycling performance. (Thus the nitrate-depleted juice served as the perfect placebo for comparison against the regular juice.)

What’s with the mouthwash?
Humans lack the necessary enzyme to convert nitrate to nitrite and get the whole chain of events going. But it turns out there are bacteria that lounge in the back of our mouths that are pros at this. The nitrate we eat goes through a rather strange and wonderful journey:

1. When we consume a source of nitrate, such as beetroot juice, the nitrate is rapidly absorbed by our small intestine. Nitrate levels subsequently rise in our blood stream and remain elevated for hours.
2. Our salivary glands suck up about 25 percent of this circulating nitrate, concentrating it in our saliva (the balance of the nitrate ends up in our urine). Saliva levels of nitrate become 10-20 fold higher than blood levels, and can peak 30 minutes after ingesting nitrate.
3. This salivary nitrate is then converted to nitrite by bacteria that hang out on the back of our tongues.
4. When we swallow, our saliva, now full of nitrite, goes to our stomach, where the nitrite is converted to nitric oxide and other nitrogen oxides. Some of the nitrite also makes its way from our stomach back into our circulation.

If we use an antiseptic mouthwash, we stop the bacteria from working. If we spit (or don’t swallow), we deny our gut the nitrite-enriched saliva.

Bacteria? Seriously?
Yes, bacteria. Communities of bacteria reside in our mouths, our nasal passages, on our skin, in our gastrointestinal tract, in our urogenital tract, and in many other places where light doesn’t shine. For each single human cell we have, we have ten (10!) microbial cells.

We have a symbiotic relationship with these microbes. As the beetroot juice research illustrates, bacteria possess enzymes we don’t have but that we need in order to digest certain foods.

We each possess a unique set of bacteria; the lint in our belly button, the dirt under our fingernails, and the bacteria in our gut help define who we are, and may affect our health. If you’ve ever consumed foods that contain probiotics, such as yogurt or tempeh, than you’ve influenced your microbial community. This is a very hot field of research and product development.

How big of a boost to athletic performance does beetroot juice/nitrate cause?
Surprisingly big. In this study average power output was increased by 5 percent during the 4 km time trial and  6 percent during the 16.1 km time trial. There were no changes in oxygen consumption, indicating cycling economy was improved.

Several studies have now shown that dietary nitrate supplementation causes an improvement in exercise efficiency and an improved tolerance for high-intensity exercise. In essence, your muscles are getting better gas mileage from oxygen.

Bear in mind this research was conducted on very small numbers (usually less than 12 participants in each study) of mostly male, college-age participants. All the research was carried out in laboratory settings. Whether the benefits extend to real-world settings has not been examined.

Geek speak:

To date, dietary nitrate supplementation has been shown to improve a number of exercise performance variables in several small studies:

• reduce the oxygen cost of submaximal cycling
• reduce the oxygen cost of low and high intensity knee extensor exercise
• reduce the oxygen cost of treadmill walking and running
• extend time-to-exhaustion during high intensity exercise

How does it work? Dietary nitrate supplementation appears to reduce the metabolic perturbation in contracting muscle cells (muscles at rest are not affected). There is a reduced rate of muscle ATP turnover at a given work rate. The mechanisms responsible for this reduced oxygen cost include increased mitochondrial efficiency (Larsen, 2011), and perhaps increased energetic efficiency of calcium transport by the sarcoplasmic reticulum Ca2+ ATPases (SERCA) (Ferreira, 2011).

The effects of dietary nitrate are not limited to athletic performance. Nitric oxide can widen (dilate) blood vessels, reducing blood pressure and increasing blood flow. Much of the current research on dietary nitrate supplementation is focusing on the prevention and treatment of conditions such as heart attacks and peripheral arterial disease (PAD). Scientists are also starting to examine the effects of nitrate on brain health.

Beetroot juice? Yuck. What other foods have high levels of nitrate?
Beetroot juice was used for the experiments because it offers a quick and easy way for research participants to consume a substantial amount of nitrate. But beetroot juice is something of an acquired taste, and it can, ahem, result in red urine and red stools.

Luckily, beetroots are just one of many vegetables and herbs that are high in nitrate. Leafy green vegetables tend to be the top sources of nitrate:

• Very high nitrate levels (> 250 mg/100 g*): arugula (rocket or rucola), bok choy, celery, chervil, collard greens, cress, lettuce, radish, red beetroot, rhubarb, spinach, Swiss chard.
• High nitrate levels (~100-250 mg/100 g): basil, celeriac, Chinese cabbage, chard, coriander, endive, fennel, kohlrabi, leek, mustard greens, parsley.

*Numbers are nitrate content, expressed as milligrams per 100 grams fresh weight, and are compiled from a variety of U.S. and European sources. Nitrate levels in vegetables can vary considerably depending on many factors, such as growing conditions.

The amount of nitrate utilized in the research studies to reduce the oxygen cost of exercise ranges from about 300-500 mg. These are levels that are readily obtained by eating a diet rich in fruits and vegetables. Here’s how some of the numbers compare:

500 ml (~17 ounces) beetroot juice          500 mg nitrate*
1 cup raw spinach                                              926 mg nitrate**
1/2 cup cooked collard greens                    198 mg nitrate**
1 cup raw leaf lettuce                                       103 mg nitrate**

* The beetroot juice used in several of the experiments was supplied by James White Drinks Ltd (Ipswich, U.K.). According to the company website, approximately 2.5 beetroots are in each 250 ml serving and the juice contains 0.1 g of nitrate per 100 ml.

** These numbers are adapted from Hord, 2009. Remember that nitrate concentrations in vegetables can vary considerably.

Participants in almost all the research studies were asked to avoid foods high in nitrate, and/or performed the exercise tests after a 3 hour (or overnight) fast. Thus they started off with low levels of plasma nitrate in their systems.

What would happen if you conducted the research on participants who consumed a diet of nitrate-rich vegetables and thus would presumably have high plasma nitrate levels to begin with? Would you see improvements in athletic performance following additional dietary supplementation? It seems unlikely as there is no evidence that higher doses of dietary nitrate increase the beneficial effects (no dose-response studies have been published).

What about hot dogs?
Nitrate and nitrite are also present in very low levels (too low to impact athletic performance) in cured and processed meats such as hot dogs, bologna, corned beef, luncheon meats, sausages and ham. They are added to enhance flavor, stabilize color, and serve as antimicrobial and antioxidant agents.

Nitrate and nitrite are considered potentially harmful at high concentrations, and their levels are regulated in food and drinking water. This regulation is the source of much debate. Researchers note that the traditional Japanese diet, the heart-healthy Mediterranean diet, and the research-based Dietary Approaches to Stopping Hypertension (DASH) eating plan all emphasize fruits and vegetables, and thus are abundant in nitrate. This has led to speculation that these diets might help protect against heart disease, high blood pressure, and type 2 diabetes in part because of their high nitrate levels. For a good discussion of the dietary issues, as well as lists of nitrate levels in foods, see Hord, 2009.

What are the risks?
The nitrate-nitrite-nitric oxide pathways can be confusing. There is a big difference between the biological effects and toxicity of nitrate and nitrite. And there is a big difference between the biological effects of inorganic nitrate, found in dietary sources such as beetroot juice and vegetables, and organic nitrate, found in drugs such as nitroglycerin.

Nitrate supplementation to enhance sports performance has become a hot topic in online forums, but unfortunately there are some misconceptions. This has raised concern among leading researchers in the field, prompting them to address potential hazards (see the Journal of Applied Physiology, August 2011 ‘Letters to the Editor’ section). Recommendations include:

• Don’t use nitrate salts and nitrite salts as dietary supplements to enhance sports performance.
• Be aware that nitrite, used intentionally or unintentionally, can have harmful effects.
• Nitrate-containing vegetable juice presents a potential risk if stored incorrectly. If the juice gets contaminated by bacteria that can convert nitrate to nitrite, high levels of nitrite could accumulate over time which could potentially be harmful.
• Nitrate ingestion from dietary sources, such as vegetables, is safe.

In addition, several medications may adversely interact with a high nitrate diet. These include nitroglycerin or nitrate preparations used for angina, and PDE-5 inhibitors such as Viagra, Cialis and Levitra. Anyone with risk factors for or diagnosed with heart disease, or with low blood pressure (hypotension), may wish to consult their healthcare professional before starting a high nitrate diet. Individuals with kidney stones should bear in mind that several vegetables that are high in nitrate are also high in oxalate (rhubarb, beetroot, Swiss chard, spinach).

The bottom line: You are what you – and your microbes – eat
It’s tempting to interpret this exciting research as suggesting that a particular substance, such as beetroot juice, provides a “new secret weapon” akin to an ergogenic aid. But all the evidence points to the slightly less sexy conclusion that the true ‘secret weapon’ to sports performance resides in your vegetable crisper. (Popeye was right all along!)

Eating a diet abundant in nitrate-rich vegetables may improve your athletic performance (as well as your cardiovascular health). Conversely, consuming a diet low in nitrate-rich vegetables may adversely affect your athletic performance (and your cardiovascular health).

To improve your performance during day-to-day training and competition:

• Aim for a serving of fruits and a serving of vegetables at each meal (If you don’t know where to start, take a look at ChooseMyPlate.gov, the DASH Eating Plan and the Mediterranean diet)
• To up your odds of improving performance for a specific event, try consuming nitrate-rich foods approximately 3 hours before the event
• Ditch the mouthwash (and don’t obsess over belly button lint or dirt under your fingernails – they probably harbor friendly, helpful microbes)
• Don’t forget the big picture. Stay well hydrated and get plenty of sleep (see Twelve Everyday Health Rules from 1908)
• Consider keeping a training log so you can look for patterns among these variables and determine what works best for you.

How do you know what’s normal?  How do you win? How do you know when to stop?

These were just a few of the wonderful, offbeat questions that popped up during a session on self-tracking I facilitated at HealthCampDC 2011.

Bring together a group of thought leaders with wide-ranging expertise. Let them debate and question the concept of self-tracking. Suddenly data and tracking take on entirely new identities.

HealthCampDC was one event of many during DC Health Innovation Week. Our discussion on self-tracking highlighted the theme of the week: how do we better utilize data to weave together stories to improve health outcomes?

Issues:

• People are lazy. Tracking systems need to be simple and intuitive.
• Diseases and conditions aren’t siloed. Tracking systems for them shouldn’t be, either.
• Community, sharing, friends, competition – these are all very important components of self-tracking.
• Community, sharing, friends, competition – there are times when these are detrimental in tracking communities and encourage negative health outcomes. Example given: anorexics who compete to see who can eat the least amount each day.
• Tracking sensors are rather worthless if they aren’t reliable and accurate.
• The Quantified Self is important, but so is the Qualified Self. Self-tracking data are not just numbers. Data can also be in the form of images and sound.
• A great example of a successful (trusted, confidential) self-tracking community? Alcoholics Anonymous.
• For many individuals who self-track, privacy is key, and sharing is the last thing they want to do. Example given: people who are HIV positive.
• Self-tracking is not  ‘one size fits all.’
• Just the act of tracking is valuable. Putting down a number or taking a photo raises awareness, which is a key step in behavior change.

Questions:

• How can SMS be better utilized for self-tracking in underserved communities?
• What are the barriers to tracking?
• How do you better incentivize or incorporate motivators into tracking devices?
• Under what conditions would it be helpful to have a tracking ‘trajectory’ to illustrate the path you’re on (good or bad)?
• How do you make tracking data actionable?
• How do you cross the self-tracking chasm from ‘work’ to ‘fun’?

Self-tracking session gurus included Marilyn Langfeld (@MarilynsView), Alan Viars (@aviars), Gregg Masters (@2healthguru), Sandra Paredes, Andrew Rainey (@breadforthecity), Greg Bloom (@breadforthecity), Richard Layman, Rebecca Frank (@frankrebecca), Andre Blackman (@mindofandre), Dave Haft (@davehaft), Eden Shiferaw (Community Education Group), Mark Scrimshire (@ekivemark), Stephen Murphy (@IQSolutions), Joe Lyons (Lyons Advisors, LLC), Baabi Das (Zansors, LLC), Jessica Sachs, Peter Speyer (@PeterSpeyer), Lindsey Hoggle (@lindseybh), Lanny Hartmann (@Lanny). Apologies to anyone I missed – let me know and I’ll add you.

What do you view as key issues and questions in the realm of self-tracking?

“Pretty awesome. RT @ageekmom: @NASATweetup How’s it feel making dreams come true with every tweetup? #burningquestion : -) ”    – Tweet from @NASATweetup, April 19, 2011.

When it comes to utilizing social media to extend a brand and engage, educate and excite an audience, NASA has the right stuff.  That was clearly demonstrated during a NASA Tweetup I attended at the NASA Headquarters in downtown Washington, DC.  NASA defines a Tweetup as “an informal meeting of people who use the social messaging medium Twitter.”

NASA provides a case study of how to successfully showcase science, or any other topic, product, or event, 140 characters at a time. Here are nine tips for out-of-this-world social media, based on NASA’s extensive media expertise.

1.  Treat your participants / followers / friends with respect.
Do you value your followers?  Do your actions show it? NASA sent a string of emails to Tweetup participants (who were chosen at random after registering online) that included a congratulatory welcome; details on the Tweetup (directions, the schedule, onsite tech availability); and a recommendation to swing by the nearby National Air and Space Museum to catch a special appearance of Robonaut 2 before the Tweetup.

At the Tweetup we received an official name badge and a swag bag full of goodies (pins, patches, stickers, fun pads and more). The event started on time and finished on time. From launch to landing, we were treated like space royalty.

What do you do for your followers to indicate how much you appreciate them?

2.  Don’t overlook the details.
There’s no point in having a Tweetup if people can’t tweet. We had Wi-Fi access with clear, written instructions on how to access the network. We were notified ahead of time that power outlets would not be available. The Tweetup, which was easily accessible by public transportation, took place in an auditorium outfitted with chairs that had desks and many folks set up laptops. Cameras were allowed. NASA created a Twitter list of participants (@nasatweetup/astro-wheels) and repeatedly provided its Twitter account and hashtag (@NASAtweetup, #NASATweetup).

How many times have you been to a social media-related event only to find you have no connectivity? If a tweet falls in the room and no one can send it, then no one can hear it and it doesn’t make a sound.

One very important, but often overlooked, detail during the Tweetup was that NASA showed the live Twitter stream, but made it small enough as to be unreadable (see left and right sides of the above photo). Tweetup participants could see that a very active conversation was going on based on the movement of the stream, but the chatter did not distract from the conversation going on among the participants in the room.

How many events have you attended where the virtual stream of tweets and retweets (RTs) overshadows the live event? When it comes to showing live Twitter streams, size matters.

3.  Provide exceptional value: Give people a reason to show up / like you / follow you.
Our Tweetup featured astronaut Doug Wheelock. “Wheels” spent six months on the International Space Station (ISS). He launched to the ISS on June 15, 2010 as part of the Expedition 24 crew. He assumed command of Expedition 25 on September 22 and returned to Earth on November 25, 2010. He worked on more than 100 microgravity experiments and conducted numerous space walks. He was known for sharing amazing twitpics from space and challenging his more than 100,000 followers to guess the locations.

“Okay…here’s one that you may need to dig out a World Atlas to find. Hint: These islands are small, remote, and i http://twitpic.com/2tiaa3“  – Tweet from @Astro_Wheels, from the ISS, Oct 1, 2010.

Other NASA Tweetups occur in tandem with shuttle launches. Granted, not everyone can offer launch pads or robotics demonstrations, but do you provide a compelling reason for people to follow you or ‘like’ you?  What do you offer that’s ‘out of this world’?

4.  Be clear about your brand and identity.
Look at the photo above. Is there any doubt who hosted the event and who is speaking? Take a look at some of NASA’s social media accounts: @NASAedu, @NASA_Technology, @ISS_NatLab, @AstroRobonaut, NASA Facebook and NASA YouTube.

Do you have a clear brand and brand strategy?  What’s your Twitter background? ‘Default’ should not be your answer.

5.  Do your social media homework and practice what you preach.
If you’re going to host a Tweetup, you should be facile on Twitter. NASA has a Twitter roster that includes astronauts, engineers, programs, projects, and yes, even robots.

“@cafferatajm I’m not awake yet, technically. But when I am awake, I can see great! I have five cameras in my head.” – Tweet from @AstroRobonaut, aboard the ISS, May 5, 2011

NASA uses a single hashtag for all Tweetups (#NASATweetup). This is extremely active and builds a sense of community. NASA creates Twitter lists for each event, and repeatedly tweets about the events.

Decide on your hashtag and key messaging well in advance. Promote them across multiple platforms so people can share news about your event before, during, and after.

6.  Repurpose your content and utilize various social media platforms.
The Tweetup event was streamed live over NASA television. You can view it on NASA’s YouTube Channel, NASA Tweetup Rolls with “Wheels”. During the Tweetup, a highlight film of Doug Wheelock’s shuttle trip aboard the ISS was shown. To sum up, NASA refilmed its own film during a Tweetup and posted it on YouTube.

Of course not everyone is on Twitter. Check out NASA’s list of social media accounts. In addition to Twitter, it includes Flickr, Facebook, MySpace, and YouTube. NASA also has created numerous apps, hosts regular online video chats, and has an extensive program of learning technologies.

7.  Be willing to make mistakes, learn from them, and move forward.
During the Tweetup, astronaut Doug Wheelock admitted that initially he didn’t know anything about Twitter, but was “highly encouraged” by NASA to tweet. “What I wasn’t realizing and picking up on, and what you guys all know, is the power and the transformation of this tweet once it hits the internet. And it’s what happens after you tweet that’s the real power in this type of media.”

Colonel Wheelock then confessed, “I had to be careful, because I actually got in trouble early on. You guys were getting these tweet pictures before NASA was getting the official photos from space. So I sorta got the cart before the horse. And I got politely scolded. I got a phone call on a private line on board the space station. ‘Hey, we don’t mind you doing this Twitter thing, but when you tweet a photo, make sure that we have it, … because we get a request coming in for the high resolution photo’ … I had to pull those back a bit and rein them in, and make sure I was downloading the photos so when you guys asked for the high resolution photos, then NASA could politely say, yes we have that for you, we’ll send it to you.”

Don’t be afraid to take one giant step forward into social media. Often times the best way to learn is by doing. (Just be sure you have social media policies in place first).

8.  Be nimble.
Go to where your audience is – or will be. What’s trendy now? Foursquare. Doug Wheelock was the first astronaut to ‘check in’ from space on Oct. 22, 2010 when he checked in to the ISS. Thanks to a NASA-Foursquare partnership, Foursquare users can earn a NASA Explorer badge (shown on Wheelock’s right arm, above) by following NASA on Foursquare and checking in to NASA-related venues. NASA was also ahead of the virtual world social media curve with two islands in Second Life back in 2007.

Where should you be that you aren’t?

9.  Connect, communicate, and most importantly, have a conversation.
Social media is not one-way communication. It’s not posting links to press releases. It’s listening and engaging in a conversation with your audience. NASA responds to questions and engages. NASA understands that people always come first and that social media is only a tool to further your dialog, educate your audience and spread your message.

NASA invests a lot of time and energy in social media. In return it gets loyal fans – lots and lots of them (over one million followers on Twitter, ~400,000 likes on Facebook). NASA’s messages go viral, and even its Tweetups garner press coverage (Los Angeles Times, NPR).

In return for its investment in social media, NASA is educating individuals about its space program, creating loyalty, inspiring dreams, and – based on the beaming faces at the Tweetup – creating future generations of astronauts who may one day share 3D twitvideos from Mars.

“‘Fly me to the Moon…let me dance among the Stars…’ I hope we never lose our sense of wonder. A passion for exploration and discovery is a noble legacy to leave to our children. I hope we set our sails and venture out one day. That will be one glorious day… ” – Twitpic from @Astro_Wheels, August 22, 2010, from aboard the ISS.

Do you weigh yourself regularly?  Do you make note of your  blood pressure or menstrual cycle? Do you note when your waist size or dress size changes? If so, you’re a self-tracker.

Self-tracking is extremely widespread. In addition to all the organized tracking communities, there’s a growing number of organic self-tracking communities. For examples, take a look at the diabetes made visible community on Flickr, or the more than 20,000 videos on YouTube tagged weight loss journey.

At the same time, sensor technology is advancing at an astounding pace. New materials and fabrication techniques, many at the nanoscale level, are leading to a host of amazing sensors that can be woven into clothes or permanently implanted into our bodies.

Mobile health (mHealth) offers the perfect platform to merge the tracking communities and sensor technologies. Toss in the power of social networking capabilities, and you’ve put the trifecta of instant ‘track, share, and compare’ at people’s fingertips.

This presentation was given by invitation at the 2011 mHealth Networking Conference to review the current status of self-tracking and sensors, and to highlight just a few of the many exciting opportunities that lay ahead.

The world of Health 2.0 has so many moving parts that are spinning so fast, that it’s tempting to gaze into a crystal ball and predict what will collide and where it will land. As we move from Health 2.0 to Health Squared, here are 7 trends I see on the horizon.

1.  Nutrigenomics & Nutrigenetics
We’re moving toward the $100 genome, and Direct-to-Consumer (DTC) genetic testing from companies such as 23andMe is on the rise. While we’re gradually learning more about the connection between our genes and our risk factors and our responses to drugs, there’s an intriguing area that has received little attention: the link between our genes and what we eat.

Nutrigenomics examines how what we eat affects our genes, proteins and metabolism. On the flip side, nutrigenetics looks at how our genetic sequence affects our responses to what we eat. Also to watch, nutraceuticals (nutrition + pharmaceuticals), which are foods and food products that provide health and medical benefits. It’s about linking the world of “-omics” with what we put in our mouths, and it will bring a whole new spin to “Eat this, not that!”

2.  Ready-to-Wear Biosensors
Advances in biosensor technology will result in clothing that monitors our every move  and mental state. The information will be automatically downloaded to our mobile devices. This advance will revolutionize health, as the ‘right place, right time’ biofeedback will lead a shift from reactive to proactive health care. Designers will compete to create self-tracking garments for pregnant women on Project Runway.

3.  Groupon Health for Baby Boomers
On January 1, 2011, ten thousand baby boomers turned 65. Each day 10,000 more will turn 65. This will continue for the next 19 years.

Groupon, Living Social, and numerous other sites that harness collective buying power will offer deals based on age, and will target the more than 75 million baby-boomers. This “silver tsunami” is concerned with healthy living and longevity, and they love getting and sharing deals. They already routinely hop online to access email, research health information, buy products, and make travel reservations (Pew Generations report, Dec 2010).

Groupon Health for boomers will focus on anti-aging options (yoga retreats, vitamin packs, golf packages, cholesterol screenings, brain exercise gadgets, pilates classes), and skip unhealthy deals (tanning salons). Boomers will be hired to find the deals for their classmates.

4.  Lies, Damned Lies, and Statistics
Given the exponential increase in biological data (take a spin around NCBI), we’ll need robust stats that help us separate the signal from the noise, tease out trends, and dissect potential cause and effect vs. random correlations.

Bioinformatics will become a trendy buzz word, number crunching will become a contact sport, and entirely new statistical models will be created.

5.  Infographics :: Data Visualization
What was once the domain of a small corner of the USA Today newspaper has gone mainstream. Daily newspapers now feature word clouds, and Hans Rosling’s talks on visualizations of global health have become TED and YouTube phenomenona.

We’re inundated with data that beg to be made into visual stories. The data stem from self-tracking (Quantified Self) and crowd sourcing (Cure Together), and from gene mapping and global mapping.

We will see even more data artfully displayed. Utilizing graphics to convey health information will increase health literacy and will consistently prove a picture is worth several thousand words.

6.  3D mHealth
New technologies are enabling 3D displays on mobile devices that don’t require the use of glasses. These are created by altering our sense of depth, using auto-stereoscopic 3D technology. This imaging will greatly enhance mobile health applications; visualize the possibilities of 3D for everything from anatomy textbooks to yoga poses. How about a 3D Pillbox?

7.  Transgenerational Social Networking
Many of our risks for diseases may be due to stretches of DNA that are not along our own chromosomes, but rather, are along the chromosomes of our parents or grandparents. This is the crux of the paradigm shifting field of  “transgenerational” genetics.

Research is mounting that suggests the genes our ancestors carried, but that were not passed down to us, can influence the traits and diseases we get. In addition, the foods that our mother ate while she was pregnant with us, and our parents environmental exposures (e.g., pesticides), may influence the traits we have, and that our children and grandchildren will have.

This throws a monkey wrench in classical genetics and merits close watch. While you don’t have to Friend your mom on Facebook, you will want to ‘friend’ her PHR – and your grandmothers – and learn everything you can about your parents health and habits.  And you’ll also want to closely track your own diet for the sake of your health (see #1), and for the health of your grandchildren.

When you look into your crystal ball, what trends do you see as we move from Health 2.0 to Health Squared?

Der Mensch als Industriepalast (Man as Industrial Palace), Fritz Kahn, 1926. (See full description below.)

Our bodies are exquisite self-tracking machines. We’re artfully engineered with rheostats and feedback loops and switches. The number of times our heart beats in a minute, the temperature of our body, the pH of our blood, the sodium concentration inside our cells, and the turning on and off of our genes are all tightly regulated.

Unfortunately, we don’t come equipped with external tachometers. We don’t have a fuel gauge that points a needle to ‘full’ to signify when we should stop eating, or a temperature gauge to indicate when we are overheating. There is no factory-installed ‘check engine’ light.

In order to make sense of what’s going on under our hoods, we can turn to a variety of tracking tools. Sensors, probes and analyzers help us detect the electrical, chemical and mechanical signals emanating from within. We can measure, track and display with respect to time and space, episode and intervention. And best of all, we get to serve as our own control: N=1.

From lab bench to park bench
As a physiologist, my life has revolved around self-tracking. In grad school, we routinely used ourselves to calibrate equipment, develop techniques, and generally see ‘what would happen if….’  We documented our lives in lab notebooks and every day was ‘show and tell.’

Self-tracking is moving out of the lab and into living rooms and bedrooms, gyms and diners. There’s a rapidly growing community, Quantified Self, that is “a collaboration of users and tool makers who share an interest in self-knowledge through self-tracking.” The site originated with gurus Kevin Kelly and Gary Wolf, and an expanding community is overseen by them, along with Alexandra Carmichael, cofounder of CureTogether. There are more than a dozen meet-up groups around the world, as well as an active Twitter community (#quantifiedself).

Long the province of elite athletes and astronauts at one end of the spectrum, and individuals living with chronic diseases (and ICU patients) at the other end of the spectrum, tracking is moving from the fringes inward. Now the bright, shiny gadgets we ordered from scientific equipment catalogs (lactate analyzers, heart rate monitors, pulse oximeters) can be picked up on Amazon.

Should you check under your hood?
Suffering from insomnia? Want to get pregnant? Training for your first 10K? Measuring any number of parameters can reveal trends and provide clues as to what makes you tick. Self-tracking can help you make a connection between what you’re feeling or sensing and how your body is doing.

You can track physiological parameters such as heart rate, blood pressure, body temperature, and blood glucose. You can track mental health parameters such as mood and self-esteem. You can track behaviors such as foods eaten, hours spent sitting at a computer, songs listened to, minutes spent exercising, and hours spent sleeping. You can track environmental influences such as outside temperature and pollen count, commuting time, number of friends on Facebook, number of neighbors on your street you know by first name.

The data provide a glimpse of what’s going on under your hood. The measures are all exquisitely intertwined and although they might not represent true cause and effect, when grouped in combination they can reveal wonderful patterns. The patterns tell a story that can provide you with insights and awareness, which may in turn lead to behavior change, thus creating a feedback loop much like your internal circuits.

Self-tracking lets you build a personal dashboard to create a narrative of yourself. It can empower you to better understand how you are functioning, and thereby put you in better control of what’s going on under your hood. And as you self-track, at some point you will cross a threshold where you view your body not only as a machine full of data points, but as an engineered piece of living art.

This year’s stellar TEDx MidAtlantic was about our choices and roles relative to our true selves, and relative to the world around us. “What if?” was the theme, and the talks seemed to focus on what parts of our brain we consciously choose to use. In fact, images of brains cropped up repeatedly in presentations throughout the day.

“Amazingly, there are cells in our left hemisphere’s orientation association area that define the boundaries of our body – where we begin and where we end relative to the space around us. At the same time, there are cells in our right hemisphere’s orientation association area that orient our body in space. As a result, our left hemisphere teaches us where our body begins and ends, and our right hemisphere helps us place it where we want to it go.”
- Jill Bolte Taylor, TED speaker, from her book, My Stroke of Insight.

Here are some of the What If’s that the speakers left us to ponder:

What if…..

You strive to be a big picture thinker?

You strive to keep your love of learning?

You embrace failure?

You find and use your own voice?

You bring every aspect of your life’s passions to bear in your work?

You focus on the business of happiness?

You strive to keep your sense of wonder?

You look at the world around you with new eyes?

You inspire and reward those around you to think creatively?

You use collective consciousness to solve big problems?

You create and build something lasting?

You give yourself space to breathe?

Using computer software programs, scientists combined brain MRIs from 20 normal people into this composite image, in which ellipsoids represent normal anatomical variations. Pink purple ellipsoids, signifying the greatest variation, occur in brain regions that are uniquely human for example, regions that control language and logical reasoning. Blue ellipsoids, representing slight variations, occur in brain regions that control sensation and movements. Ultimately, this baseline data on interpersonal variability will allow scientists to distinguish normal anatomical variation from abnormal brain loss, such as that seen in Alzheimer’s disease.

Note: Dr. Marshall Warren Nirenberg received the Nobel Prize in Physiology or Medicine in 1968 for deciphering the genetic code. He was born in New York City on April 10, 1927, and died January 15th, 2010. Marshall spent over 50 years working at the National Institutes of Health (NIH). At a memorial service at NIH in his honor on October 8, 2010, friends and colleagues gathered to paid tribute to this titan of science. One of the speakers was Norma Zabriskie Heaton. She is shown above on the left, with a slide rule and lab notebook in her hands. Following are highlights of her tribute.

Guest post by Norma Zabriskie Heaton.

I was one of Marshall’s technicians, along with Theresa Caryk and Linda Greenhouse, when the genetic code was cracked and deciphered, and I continued to work for him for almost 40 years.

When Marshall interviewed me for the job in 1963 he told me he had an idea that would involve working with cockroach legs. I didn’t like bugs, but I took the job anyway and am glad I did. (We never did use cockroach legs.)

I would like to take you back to those early days and share with you what it was like working in the lab when the genetic code was deciphered. The lab work was intensive, exciting, and downright fun. But it could also be frustrating, stressful and tedious.

How many people have the opportunity to work on a project that is so significant and fulfilling? The challenge sometimes was to see beyond the repetition to the goal. Sometimes I thought that if I had to do one more binding assay protocol I’d scream. But the repetition was just Marshall’s obsession with accuracy and reproducibility.

Marshall was modest, soft-spoken and kind. He was a true gentleman and it was his nature to be generous with praise. He was very creative and had so many ideas – he liked to try them out with fast little experiments just to see where they might lead – he called them “quickies.”

Marshall was very focused and demanding. He had a meticulous and painstaking approach to data analysis and when you discussed your results with him, he expected you to know your experiments inside and out, backward and forward. No detail was overlooked or insignificant to him, and you had better know which solutions you used, who made them, when they were made, how they were made and the lot number of every reagent.

Marshall didn’t keep the same hours as the rest of the lab. He might arrive anywhere from mid-morning to early-afternoon and he would always work very late into the night. “How goes it?” was a typical greeting.

He wrote out the protocols to follow and left them on the lab bench. His handwriting could be challenging to decipher, but, like learning a foreign language, it became easier with time. He told me it was because he was a natural lefty, forced to learn to write with his right hand.

The labs were all crowded – we didn’t work side by side – it was elbow to elbow. It was so busy that Theresa labeled our TCA reagent in Ukrainian so that it didn’t wander off. Marshall had a tiny office in the back part of our single module lab just wide enough for his desk, two chairs and a file cabinet, and you usually had to clear off a chair in order to sit down.

Marshall and Phil Leder devised what became known as the binding assay. This was the assay that we went on to use to decipher the 64 triplets of the genetic code. Marshall was always pleased when we could end the week with a successful experiment, so when I ran the first binding assay just before the Thanksgiving holiday in 1963, it was a high note.

I will never forget hearing the shouts, especially from Ed Scolnick and Mert Bernfield, when the latest codon result would come off the Nuclear Chicago planchet counter tucked into a tiny alcove in the hallway. Marshall was always just as delighted but his reaction was more restrained – he might pump his fist and say “wonderful.”

Some of you will recall that back in the olden days, there were no calculators so we used slide rules to get our results. This was before the days of personal computers and spreadsheets so tabulating a summary of our results as each triplet codon was deciphered was challenging. I taped enough data paper together to create very large charts and drew the columns and rows with a ruler. Then, I painstakingly entered all the data from our experiments by hand. The resulting charts would become the “Rosetta Stone of the Genetic Code” and some of them are now in the Smithsonian and the Library of Medicine.

Manuscripts were written and rewritten, typed and retyped ……. often up until the last moment before the deadline. This was before the days of e-mail and fax machines, so when Marshall and the secretary finished his paper for the Lasker Foundation award at 3 a.m. the morning of its deadline, Marshall left me a plane ticket and I flew to New York and hand delivered his paper to the Lasker Foundation headquarters. The very next morning was Wednesday October 16th, 1968 and it was announced that Marshall had won the Nobel Prize.

Marshall had many interests, and one of them was archeology.  He told me he had even once considered it as a field of study for himself.  So I asked him, if he had the opportunity to go back in time to see and relive the past or to go forward in time to see into the future, which would he choose?  And, without hesitation, he said he would want to go forward.

By the time Marshall had won the Nobel Prize he was already looking forward to studying the brain and the nervous system.

Marshall had an inquisitive mind, the capability to ask the important scientific questions, and the discipline to seek the answers. He set high standards and recognized that ethical responsibility must go hand in hand with scientific discovery.

He knew that knowledge was what would last and endure for all eternity and that the knowledge we amassed was a legacy that would live on.

He emphasized to me that I should always be proud of my contribution to this knowledge.

I will always treasure the memory of this extraordinary man and I am so grateful I had the opportunity to know and work with him.

Norma Zabriskie Heaton is now retired and spends her days obsessed with genealogy. She and her husband live with their 2 dogs and cat in an old stone farmhouse which she and her husband have restored.  She also enjoys gardening, needlework, reading and listening to music on her iPod.

“Oh my God!!!!  We’re allowed to touch!”

“Look at the sign!”

Those were the squealing voices I heard recently at the brilliant Da Vinci-The Genius exhibit at the National Geographic Museum in Washington, DC.  The exhibit showcases full-scale machines, reproductions of famous Renaissance paintings, and detailed anatomical sketches from Leonardo da Vinci. The interactive inventions are beautifully crafted by Italian artisans working from Leonardo’s codices. And almost everywhere are signs that read, “Please touch.”

Kids were running all over pulling and pushing levers and laughing and squealing. And so were adults.

The interactive exhibit provides a clear reminder that as humans, we are  designed to manipulate objects in our world. To touch, grasp, push, pull, clutch, rotate, stroke, manipulate, poke, and hold. Perhaps no one personifies this ability better than da Vinci, who used his hands as an inventor, artist, scientist, anatomist, engineer, architect, and sculptor.

Exhibits should not be spectator events. Museum curators would be wise to watch kids interact in this space. One of the kids may be a future da Vinci.
