BOSTON - From clothes riddled with sensors to name tags that detect our moods, computing's next wave could unleash small devices that increasingly augment everyday activities with digital intelligence.
That was the predominant vision at a conference on ''wearable computing'' held this week in Boston, where researchers showed off prototypes and discussed ideas.
Some attendees took wearable computing to its extreme, donning cyborglike miniaturized displays attached to eyepieces. But most of what was on exhibit seemed much closer to jumping into a mainstream commercial product.
For example, researchers from the Swiss Federal Institute of Technology (known as ETH Zurich) showed off stretchable, threadlike sensors that can be woven into shirts to detect their wearers' posture. People with back pain or injuries could be prompted on a PC or a mobile device to straighten up, pronto.
Stephane Beauregard of Germany's University of Bremen displayed a sensor that provides real-time location tracking in places satellite navigation systems either can't reach or can't describe. Beauregard expects a version that can fit inside a boot heel could be a year away. His first intended market is emergency responders.
Graduate students at the Massachusetts Institute of Technology's Media Lab had black plastic badges around their necks that analyze multiple factors to detect the level of engagement two people are exhibiting in a conversation. Information gathered from the badges, which weigh just a few ounces and are a bit smaller than a deck of cards, can be sent wirelessly to a computer or a phone to give their wearers helpful tips. Sales reps could be advised that a customer's interest seems to be waning. A doctor could be alerted to indications of depression in a patient being monitored remotely.
The badges might find their first use in gathering reams of data for social network analysis, the study of how groups form and interact. There's big money in applying such research in corporations, which want to ensure that important knowledge doesn't stay trapped in organizational silos. But a lot of data for social network analysis is gathered from e-mail traffic, which only says so much about how people connect with each other.
MIT graduate student Daniel Olguin Olguin said the devices were tested on 25 employees at a German bank and produced surprising insights about alternative ways the office might be laid out. Now Hitachi Ltd. is interested in making the badges, he said.
Each badge likely could be made for less than $100, ''and in the future, of course, all of this will be smaller and integrated into your name card,'' Olguin said.
A prototype shown off by Carsten Mehring of the Colorado School of Mines was far more about convenience. He has embedded sensors into gloves so snowboarders or motorists could control portable music devices with the faintest squeeze of their fingers without looking away.
''The idea is to wear your remote, not to carry it,'' he said.
