Preceding Motion in A Hand Tracking Experiment
We conducted a series of psychophysical experiments of hand motion in tracking a sinusoidally moving target and found, by direct sampling and a detailed statistical analysis, that the operating point of hand motion does precede target motion systematically when the frequency range is from 0.3 Hz to 1.3 Hz. Furthermore, we showed that the positional error in a cycle immediately following a sudden increase of frequency is minimal when the time difference just before the change is close to the mean value of the overall time difference observed in a steady run. The present experimental results indicate that the sensory-motor control system of human beings sets its operating point at a time which precedes target motion such that it minimize future error for a possible change of target motion in an ordinary frequency range.
