At MIT we designed and built the required technology to gather the physiologic data off the climbers - data to be analyzed by doctors. A weather station was also built. It was left on the summit of Everest to transmit data, via satellite, back to the lab. RadioSpace provides awareness of people and their presence in physical space and time IR-based position tracking allows location awareness of nomadic users with wearable computers. A position-server maintains a history of user interaction and movement in space and time.
Users can send messages to other users or to rooms.
Dynamic web-based maps allow users to view the location of others and passively listen to cues indicating their activity. This project was done by Lisa Stifelman as her Ph.D. thesis. Check her page for details. Another system I demo is Nomadic Radio . This is a project of Nitin Sawhney.
