In order to examine the frequency of a target wave and induced eye movements we designed and developed a new target wave (continuously changing sinusoidal wave). This target wave consisted of 20 sinusoidal waves from 0.1 to 2.0 Hz with 10° amplitude (peak-to-peak amplitude is 20°). Several parameters were calculated quantitatively with a microcomputer in normal subjects, and the following conclusions were obtained: The amplitude gain (peak-to-peak amplitude of eye movements/peak-to-peak amplitude of the target wave) and the retinal error velocity were appropriate parameters for representing the input and output of smooth pursuit. The limit of smooth pursuit was 1.2 Hz.
