There are 5 types available: ETT (pursuit eye movement) mode in which the circular target moves sinusoidally, Saccade (saccade eye movement) mode in which the circular targets are randomly presented at different positions, OKN (optokinetic eye movement) mode in which the stripe target moves unidirectionally. Caloric ETT and Caloric OKN (visual-vestibular interaction) mode, which are used in the caloric test (caloric vestibular stimulation).

In Caloric ETT mode, caloric vestibular stimulation starts as soon as a red circle is displayed for 1 second after 10 seconds. Fix the black circle at the center for 10 seconds after 100 seconds (visual suppression). Instructs to follow a black circle that moves sinusoidally after 115 seconds.
In Caloric OKN mode, caloric vestibular stimulation starts at the same time as a red circle is displayed for 1 second after 10 seconds. Fix the black circle at the center for 10 seconds after 100 seconds (visual suppression). Instructs to look at each one of the moving targets in one dire
