Video-based eye tracking: our experience with Advanced Stimuli Design for Eye Tracking software.

We present an independent, flexible, and easily programmable software program for generating a wide set of visual stimuli paradigms in eye-movement studies. The software, called ASTIDET (Advanced Stimuli Design for Eye Tracking), has been interfaced in real time with a high speed video-based eye tracking system in order to obtain a reliable measurement of saccades. Two saccadic paradigms have been tested (gap and memory guided tasks) in 10 normal subjects. The preliminary results confirm that ASTIDET is a user-friendly software and can be interfaced with a video-based eye-tracking device in order to obtain reliable measurement of saccades.
