  • Head Motion Tracker

    Dear all,
    I am a systems engineer working on a wearable system that will classify
    sounds and localize them relative to the user. The acoustic sensor array is
    to be mounted on a helmet. The user may have moved before he/she looks at a
    display device to determine where the sound came from. As a result, it is
    necessary to know the orientation of the head and the movement of the head
    since the acoustic event. Thus, I need to incorporate or develope a head
    tracker component.
    The questions I'd like answered are:
    Does anyone know of a head tracking device that is capable of sourceless
    (all sensors on person) operation in all 6 DOF. It would be incorporated
    into a real-time processing system that is worn by a person in an
    unrestrained environment.
    What are the acceleration and angular displacement limits of the head.
    I would be happy if someone could help me. Of course, I will send a summary
    of the responses to BIOMCH-L.
