ISAAC: a voice activated speech response system for wearable computers

ISAAC (Integrated Speech Activated Application Control) is a technology feasibility prototype which explored capabilities in the low-weight, low-energy area assuming communication over short distances. ISAAC employs speech for communicating with infrastructure in special rooms around campus. A wireless microphone transmits analog speech to a speech recognition system on a base computer: The base computer can control devices through infrared repeaters. It also communicates with the user via an infrared wireless headset. The user can read electronic mail or control the presentation (e.g., VCR, slide projector etc.) using audio input/output.
