Two Dimensional Eye Tracking. Sampling Rate of Forcing Function.

Abstract

This study was conducted to determine the minimum update rate of a forcing function display required for the operator to approximate the tracking performance obtained on a continuous display. Previous studies using time on target as a measure of performance, obtained a breakdown in performance around 15 samples per second. In this study, frequency analysis was used to determine whether there was an associated change in the transfer function characteristics of the operator. It was expected that as the forcing function display update rate was reduced, from 120 to 15 samples per second, the operator's response to the high frequency components of the forcing function would show a decrease in gain, an increase in phase lag, and a decrease in coherence.
