Abstract:

The purpose of the study was to investigate human force and motion- sensing mechanisms, to develop models for the prominent or potentially artificially stimulatable mechanisms, to implement them on an analog computer, and to investigate their responses to various force and motion-forcing functions. Models were implemented and tested for a semicircular canal, the otolith, head motion muscle spindle sensing, and body seat pressure sensing. Tests of the models have demonstrated the relative time delays between applied force and perceived force for the various mechanisms, showing that both the muscle spindle and pressure-sensing mechanisms perceive an applied force much more rapidly than the vestibular system. Also, the long adaptation phenomenon associated with the semicircular canals which seems to degrade their usefulness in flight and the rapid adaptation phenomenon associated with the pressure sensors which makes them important sensors for consideration in the design of motion systems have been shown through model testing.
