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

Area of Science:

• Ophthalmology and Vision Science
• Neuroscience
• Computer Science

Background:

• Accurate measurement of saccades is crucial for understanding eye movements in various neurological and visual conditions.
• Existing software for generating visual stimuli for eye-tracking studies can be inflexible or difficult to program.

Purpose of the Study:

• To introduce Advanced Stimuli Design for Eye Tracking (ASTIDET), a novel, user-friendly software for creating visual stimuli paradigms.
• To validate the real-time interfacing of ASTIDET with a high-speed video-based eye-tracking system for reliable saccade measurement.

Main Methods:

• Developed ASTIDET, an independent and programmable software for visual stimuli generation.
• Interfaced ASTIDET in real-time with a high-speed video-based eye tracker.
• Tested two saccadic paradigms (gap and memory-guided tasks) in 10 healthy participants.

Main Results:

• ASTIDET demonstrated flexibility and ease of programming for diverse visual stimuli.
• The software successfully interfaced with the eye-tracking system, providing reliable saccade measurements.
• Preliminary results confirmed the user-friendliness and efficacy of ASTIDET in saccade analysis.

Conclusions:

• ASTIDET is a valuable tool for researchers conducting eye-movement studies, offering a flexible and programmable solution for visual stimuli generation.
• The software's seamless integration with video-based eye trackers ensures reliable data acquisition for saccade analysis.
• ASTIDET facilitates user-friendly and accurate saccade measurement in research settings.
