A low-power headset with a sensory system and a short-range wireless radio transceiver can become a highly context-aware peripheral device, but to avoid affecting the user as much as possible, the amount of components should be minimized. A combination of low-power motion sensors and microcontrollers achieves this by translating situations concerning the user's behavior into corresponding symbolic codes. In addition, a low-power Bluetooth radio module configures a flexible personal-area computing system by invoking Bluetooth's secure ad hoc networking capability. As a result, the headset can work as an always-ready wireless context interpreter for at least eight hours without having the user take care of the existence of device in terms of both physical and mental obtrusiveness.
