BOSTON -- From clothes riddled with sensors to name tags that detect = our=20 moods, computing's next wave could unleash small devices that = increasingly=20 augment everyday activities with digital intelligence.
That was the dominant vision at a recent conference on "wearable = computing"=20 in Boston, where researchers showed off prototypes and discussed = ideas.
Some attendees took wearable computing to its extreme, donning = cyborglike=20 miniature displays attached to eyepieces. But most exhibits seemed much = closer=20 to jumping into mainstream commercial products.
For example, researchers from the Swiss Federal Institute of = Technology=20 showed off stretchable, threadlike sensors that can be woven into shirts = to=20 detect their wearers' posture. People could be prompted to straighten = up.
Stephane Beauregard of Germany's University of Bremen displayed a = shoe-borne=20 sensor whose tiny accelerometers perform dead reckoning -- providing = location=20 tracking in places satellite navigation systems can't reach or can't = describe=20 precisely. For now, the sensor is held in place by shoelaces, but = Beauregard=20 expects a version that can fit inside a boot heel within a year. His = first=20 intended market is firefighters and other emergency responders.
Graduate students at the Massachusetts Institute of Technology's = Media Lab=20 had black plastic badges around their necks that analyze multiple = factors --=20 including motion and speech patterns -- to detect the level of = engagement two=20 people are exhibiting in a conversation.
The badges might find their first use in gathering data for social = network=20 analysis, the study of how groups form and interact. There's big money = in=20 applying such research in corporations, which want to ensure that = important=20 knowledge gets used.
MIT graduate student Daniel Olgu=EDn Olgu=EDn said the devices were = tested on 25=20 employees at a German bank and produced surprising insights about = alternative=20 ways the office might be laid out. Now Hitachi Ltd. is interested in = making the=20 badges for corporate consultants to use with their clients, he said.
Each badge probably could be made for under $100, "and in the future, = of=20 course, all of this will be smaller and integrated into your name card," = Olgu=EDn=20 said.
A prototype shown off by Carsten Mehring of the Colorado School of = Mines was=20 far more about convenience. He has embedded sensors into gloves so that=20 snowboarders or motorists could control portable music devices with the = faintest=20 squeeze of their fingers -- and nary a glance away from a snowy slope or = the=20 road.
"The idea is to wear your remote, not to carry it," Mehring said.
