Abstract : In this Phase 1 project, the feasibility of a compact completely body-worn and wireless means for sensing and communicating a human?'s position and body segment orientation in 3D space was demonstrated. The 'total human' - 'total system' approach introduced emphasized: (1) the study of human motion characteristics, (2) the human factors of such systems, and (3) exploritation of rapidly evolving base technologies (e.g., inertial guidance and earth magnetic field sensors, wireless local area networks, low power electronics, and rechargeable batteries). A system concept called the Human Position and Orientation Sensing System (HPOSS) was specified. With reference to Global Positioning Systems, we have coined the term Local Position and Orientation Sensing System (LPOSS), of which HPOSS is a particular type. HPOSS consist of five multiple body segment sensor units (MBS-SUs; two arms, two legs, and one torso) and a single base unit (to be produced in 1,3, and 5 channel versions). The base unit communicates the requistite data via serial interface in a unique format intended to provide a standard fora new generation 6f high fidelity human-computer interfaces. Prototypes of selected subsystems were prototyped, tested, and demonstrated in laboratory conditions. Prototypes using both magnetic and inertial sensors were 'OVER' tested.
