Optic stimulus used for human oculomotor system or eye-hand coordination researches is often represented on a computer screen. They must be synchronised with the eye tracker to achieve the accurate results of the conducted experiments. Relation between stimulus presence and eye image capturing times can be defined only with reference to knowledge of all system delays. The suggested research evaluates our eye tracking system delay and propose a practical method for measuring and evaluating delays to the computer graphic subsystem. Experimental research shows that LC Technologies eye tracker reports gaze angle with 28 ms lag and the average stimulus lag of the computer graphic subsystem is 9,5 ms.
