Body Tech Dec/Jan 2001 Someday - and someday soon - technology will
fuse with the human form. A report from the
front lines of wearable computing. One (Dec/Jan, 2001) Body Tech By David Pescovitz Two years ago, when I spotted someone walking down the street having a heated conversation with himself, my immediate reaction was: "How sad, another schizophrenic." Things have changed. Now when I see a suit-wearing schizo bustling through the Financial District, an increasingly common occurrence, I just look for the wire running from his ear into the mobile phone in his pocket. These hands-free jabberjaws are the advance scouts in the nascent wearable-computing revolution. In 1972, the first digital watch wowed the world with its bright red display and space-age design. Less than 30 years later, cell phones are practically comparable with Dick Tracy's wrist radio, and handheld personal digital assistants have nearly made the Filofax obsolete. Meanwhile, Levi Strauss & Co., Nike and even IBM are putting a fashionable face on totable technology. Combine wireless Internet access with a just-announced full-blown PC the size of a matchbox and new eyeglasses rigged with a tiny video display, and you can search an online restaurant guide to find the best vegetarian dim sum as you see the sights in Chinatown. Or comparison-shop online while you're browsing in a brick-and-mortar retailer. Or add a tiny video camera and stream your child's fun in the park to your spouse stuck at work. And that's just what you can do today. In the foreseeable future is technology under development at the Massachusetts Institute of Technology (MIT) Media Laboratory that enables your body to act as the conduit for your own Personal Area Network. Imagine, you shake hands with someone and instantly exchange digital business cards, which are stored in tiny computers hidden in the soles of your shoes the data streamed as low-power electricity right through your body. Inspector Gadget, meet the Six Million Dollar Man. "Instead of intelligent highways, smart rooms, smart floors and smart television sets, we should consider having 'smart people,'" says Steve Mann, a professor at the University of Toronto and pioneer of wearable computing. I briefly met Mann in person several years ago; his reputation preceded him. I had heard tales of a small group at the MIT Media Lab, where Mann studied, who nearly all their waking hours wore headgear rigged with small screens and cameras controlled by bulky belts packed with sensors, microprocessors and batteries. They were exploring issues of constant connectivity, electronic surveillance, and what they called "augmented reality," online information continuously streamed into their field of view. Mann told me that he was designing "second-brain devices that were true extensions of the mind and body." In casual conversation with me, Mann seemed chronically distracted either I bored him, or he was checking his email, or both. Ironically, he came across as more machine than, well, Mann. And the feeling of alienation I was flooded with when we spoke was certainly something to reckon with. Today wearable-computing contraptions have shrunk tremendously, yet the issues of techno-etiquette, privacy and human-computer interaction that Mann and his colleagues have raised are bigger than ever. And as the wearable computer spreads into the mass marketplace, a counterrevolution is beginning to brew as well. The sign taped on this San Francisco café's door is barely noticeable it's scrawled on a piece of notebook paper but once it catches your eye, the message comes across loud and clear: No mobile phones. A tiny boutique record store nearby has a similar sign posted in its window. Across town, at a bookstore founded by a Beat poet, the same demand is directed to browsers in a more creative manner: Turn off your sell phones! At the core of this attack on body tech is the fear that we're becoming cyborgs, a term that MIT's wearable researchers use (only half-jokingly) to refer to themselves. The sci-fi inspired concern is that by integrating electronics so closely with our bodies we're becoming somehow less human. And that's admittedly a scary notion. But that's not the reason why, when my cell phone rang to the tune of Beethoven's Fifth in that café, I was attacked by evil eyes. The questions we face are not just how design dictates how we relate to computers, but how the design of computers impacts the way we relate to each other. "We have had millions of years of evolution of how we pay attention, how we allocate our attention to the world around us, and wearable computers change our relationship to that space," says professor Judith Donath, director of the Sociable Media Group at the MIT Media Lab. "When you're in a public space with other people, part of the notion is that we're all here together. But with cellular phones, there's the sense that those people on the phones have removed themselves from that public space into some other realm. And you're kind of left behind. So it's interesting to think about how the design of future devices could be less intrusive." One way to do that, Donath suggests, is to take a step back from technofetishism, in this case technology for technology's sake, and ask basic psychological questions about how we use the devices we already own. For example, what is it about a wearable computer as simple as a cell phone that we find so annoying? Answer: people talking on them. And therein lies the irony. The very act of withdrawing from the public space in order to take a call is also an act of intrusion. Chatting on the go is one thing, but running into an on-call mobile worker at a party is a whole different story. Quite simply, you can't have two conversations at once. Or can you? Text messaging, where short missives are fired back and forth wirelessly via pagerlike devices or cell phones, is extremely successful in Europe and Asia, Donath notes. Handheld email devices from Motorola and Research in Motion are available in this country as well, and make use of tiny keyboards and small LCD screens as interfaces. On the recent crop of Web-enabled cell phones, you input text by scrolling through the characters on the keypad. The practical beauty of these devices is that during your downtime in public spaces you can keep the channels of communication open without tuning out the world around you. The design challenge then is to develop the ultimate input device for wearable computers. That's where Stanford University professor Vaughan Pratt's attention is focused. Pratt recently spun out a commercial version of his Matchbox PC, the world's smallest computer capable of running Windows. Plug a head-mounted display and a portable keyboard into the Matchbox PC and you become your desktop. But while wrist-worn mini keyboards and other handheld data entry devices are available, Pratt has come up with his own unobtrusive input scheme for wearable computers: Thumbcode, a "device-independent, digital sign language." "You simply say, 'Okay, my hands are my keyboard,' and you use your thumbs to press on the segments of your fingers [to transmit letters]," Pratt says. The prototype Thumbcode input devices his group at Stanford have developed consist of gloves wired with sensors that act as the keys of a keyboard when you press on them. "If you've got your hands as your only typing device, then there is no limit to how small the rest of your wearable computer system shrinks," Pratt says. But ingenuity aside, the bottom line is that a silicon accessory has to be visually appealing in order to entice people to put it on before they leave the house every morning. For better or worse, aesthetics are likely to be more important than politeness, at least initially, when it comes to wearable computing. This is less of a concern with commercial applications, wearable computing's current, if limited, stronghold. One company, Fairfax, Virginiabased Xybernaut, is a leader in wearable technology for repair, maintenance and inspection workers. For example, an aircraft mechanic wearing a Xybernaut head-mounted computer has instant access to a searchable technical manual right before his eyes, which he can control using voice-recognition technology. Xybernaut has plans for the consumer sector, too. Michael Jenkins, Xybernaut's vice president and chief technology officer, foresees scenarios like a homeowner reading instructions for building a deck via an eyeglass display instead of running indoors to rewind the home-improvement video. But he's quick to point out that "you're not going into a bar on a Friday night wearing this thing." You would though if the gear weren't too geeky. Instead of uploading the directions to your deck, envision accessing a digital address book complete with digital snapshots to your wearable device. You run into someone at the pub who seems to know you quite well, but you're drawing a total blank on their name. A tiny video camera built into your eyeglasses snaps their mug and the PC scans your database until it matches their face. Instantly, a secret reminder pops up in the corner of your eye with a reminder of who you're talking to and how they know you. But before video cameras and eyeglasses with onboard screens become hip fashion accessories, product designers must destroy the stigma associated with wearing your technology on your sleeve. That's one idea behind ICD+ (which stands for Industrial Clothing Division), a new line of clothing from jeans giant Levi's and Philips Electronics that merges utility wear with wearable computing. The ICD+ line launched four jackets for on-the-job urban nomads. Each style which are sort of Mad Max-meets-Carhartt is tricked out with a cell phone, an MP3 player and a chest-mounted remote control enabling easy operation. The devices are linked by wiring in the coat's lining so that each bit of electronics works hand-in-hand with the rest. For instance, when a call comes in, the volume of music from the MP3 device automatically lowers. Each coat is targeted to a specific industry the all-climate Producer jacket, with numerous pockets, is aimed at on-the-set Hollywood types while the durable Beetle jacket is custom-built for scooter couriers on delivery trips. The clothing is planned for modularity: The jackets could link with yet-to-be-announced garments like shirts with keypads in the sleeves, for instance. Dry-clean only? Nope. The devices are removable; the wiring impervious to water. Currently, the first jackets are undergoing, er, beta-testing in Europe. Only 2,500 of the $1,000 coats were produced. If the jackets catch on, mass production paired with the ever-dropping cost of mobile electronics will likely lower the price of the ICD+ line. Regardless, the big barrier to U.S. introduction is the incompatibility between European and U.S. wireless communication networks. "Levi's is famous for developing the first workwear, the first denim jeans for the gold miners in the 1850s," says Peter Bas, Levi's brand manager for the ICD+ line. "Now with this new line we are pioneering new forms of workwear, for the new modern worker, the new gold miner." Make that data miner, the 21st century counterpart. While Levi's is using the ICD+ line to target "millennial workers" road warriors of one sort or another other companies are going directly for the mainstream with fashionable wearable technology. Nike is integrating MP3 players into its sportswear, and Samsonite launched their Blacklabel Travel Wear line, rigged with simple devices like reading lamps and alarm clocks. Even IBM, the quintessential example of corporate geekdom, is dabbling in computer couture these days. While one division of Big Blue is collaborating with Xybernaut on the next generation of wearable computing for commercial applications, IBM's future-forward Almaden Research Center, in the heart of Silicon Valley, is developing a line of digital jewelry created by Denise Chan, a recent graduate of Stanford's School of Engineering, who hooked up with the company at a job fair. As legend has it, the idea was sparked by an out-of-character comment from Almaden Director Robert Morris, who muttered that he'd be willing to pierce his ears if it negated the need to wear a headset for mobile communication. The result? Demo devices like earrings with tiny onboard speakers and a ring with a built-in TrackPoint, the nipple-like cursor controller found on IBM ThinkPads. Further along are the elegant offerings of Charmed Technology, a Los Angeles firm that spun out of the MIT Media Lab to commercialize wearable-computing couture. Indeed, the CTO of the company is Thad Starner, who, along with fellow Media Lab alum Mann, the first cyborg I closely encountered, are arguably the preeminent envelope pushers in wearable computing. Currently, the company is best known for its successful series of Brave New Unwired World fashion shows which merge spacey runway fashion with wearable technology from numerous developers, including Xybernaut, Motorola and others. Their first two signature products, due out this month, include the Charmed Communicator, a PC in a belt buckle with a display inside sunglasses; and the Charmed Badge, which automatically transmits its wearer's electronic business card to other users via infrared. Katrina Barillova (who formerly worked in the security surveillance industry) is the 27-year-old Czechoslovakia-born chief operating officer of Charmed. "People are afraid to look like cyborgs," she has said. "Our goal is to make technology fashionable and to incorporate these items into everyday lifestyles." While Charmed, along with Levi's, IBM and other companies, is racing toward making aesthetic improvements of today's wearable computing, the social impact of the technology's far-future applications remain largely unresolved. And the annoying symphony of cell-phone rings is just the first cue encouraging us to consider how wearable technology can become as banal as it is empowering. Extrapolate a scenario from this example: the impressively inexpensive yet conceptually advanced key-ring computer, the Japanese Lovegety. Users enter into the Tamagotchi-like device whether they're in the mood for "love," "chat," "drink" or "movie" and the Lovegety beeps whenever they're within 30 feet of another Lovegety-carrying individual with whom they're "compatible." Now expand the Lovegety's preference possibilities (foreign films, loves kids, etc.) along with its range, so it can cover entire neighborhoods or even towns. "At its worst, it turns every city into a giant singles bar," Donath says. A next-generation Lovegety could bring the "Buddy Lists" of virtual chatrooms into the physical realm, providing a pleasant surprise by alerting you that your best friend happens to be in the next café over, or tracking your child if she's lost. The key for designers is to incorporate a host of custom-control features into the product, enabling you to block what information you'd like to broadcast and to pick and choose who receives it. "Wearable computers are not handcuffs," Pratt says. "No one forces you to wear them." True, but even if you're not wearing one they still can make you feel like a prisoner of the datasphere. Take the research of Ph.D. candidate Bradley Rhodes at the MIT Media Lab. Rhodes has designed a system he calls a Remembrance Agent, a program that continuously "watches over the shoulder" of the wearer of a wearable computer and displays one-line summaries of notes, files, old e-mail, papers and other text information that might be helpful to the user at any given moment. The benefits of having a Remembrance Agent in your peripheral vision are enormous. Picture wandering around a museum and having background on each artifact you see automatically pop into view. Or the notes from a talk someone gave that you saw several years ago displayed in your peripheral vision the instant you shake that person's hand in real life. Now imagine meeting a person wearing a Remembrance Agent system at a dinner party. As soon as your name is entered into his wearable computer, either transmitted by the likes of a Charmed Badge, or entered manually, a full Web search of you begins. The problem (actually, not a problem), is that a person is much more than their home page, resume or list of favorite films. "The physical world around us has lots of information in it that we are subconsciously picking up," Donath says. "When we add a whole new data-stream, we really need to think about how we control it, especially when you could be paying attention to it later. Otherwise, you may lose a lot of subtle, hard-to-articulate information if you're looking at a person's Web site instead of into their eyes." Turning off the Remembrance Agent may be akin to dispensing with a built-in bullshit detector. But you can always do your Web search after the party ends, instead of missing out on the very things that make us yearn for real-world interaction to begin with. "I'm curious to what extent people are going to adapt to these new devices as opposed to the devices' adapting to our existing mores." Donath adds. And, lest we forget, there's always the "off" switch.
