Enhancing eye tracking for nonhuman primates and other subjects unable to follow instructions: Adaptive calibration and validation of Tobii eye trackers with the Titta toolbox.

ABSTRACT: Accurate eye tracking is crucial for gaze-dependent research, but calibrating eye trackers in subjects who cannot follow instructions, such as human infants and nonhuman primates, presents a challenge. Traditional calibration methods rely on verbal instructions, which are ineffective for these populations. To address this, researchers often use attention-grabbing stimuli in known locations; however, existing software for video-based calibration is often proprietary and inflexible. We introduce an extension to the open-source toolbox Titta-a software package integrating desktop Tobii eye trackers with PsychToolbox experiments-to facilitate custom video-based calibration. This toolbox extension offers a flexible platform for attracting attention, calibrating using flexible point selection, a
