In this study, we showed several “hole” patterns for a few seconds on a computer screen while, using an infrared eye tracker, we recorded the
Nov 22, 2025
Three artificial eyes with different fixed pupil sizes were used to systematically measure changes in pupil size as a function of gaze position with a desktop EyeLink 1000 tracker.
Jul 31, 2025
The high-resolution image of the eye necessary for gaze tracking also enables a high-precision measurement of the size of the pupil. This additional measurement is useful, because small, short
Feb 12, 2026
Most eye trackers used in cognitive pupillometry use head-mounted cameras or chin rests, because a fixed camera-pupil distance enables good pupillometric precision. In contrast, remote eye trackers,
