Evaluation of vibration-induced changes in oculo-manual tracking using process identification

This research was aimed at defining the extent of oculo-manual tracking performance degradation due to hand vibration. Changes in tracking performance were evaluated using process identification. The contribution of the nonlinear component to the eye/hand response was used as an indicator of the effects of vibration on each tracking system. The results indicated that during hand vibration the eye and hand remnants increase. Vibration-induced alterations of the proprioceptive system, and thus the sensorimotor control loops, are suggested to be the primary cause of remnant increase.<>
