Abstract
- This study aims to investigate visual tracking task of Koreans to the various visual stimuli by measuring the horizontal saccadic reaction times. The measuring system consists of eye monitor using infra-red reflection technique, oscillographic recorder and forehead-chin fixation devices. The visual stimuli generated by target function generator displayed simple-step, pulsestep and double-step stimulus patterns. The results revealed that the sacoadic reaction time showed no significant changes between the size of target displacement within horizontal 20 degrees. Furthermore, no significant changes between the particular direction of stimulus could be found. The nominal value of reaction time was 259 +/- 25 msec.
