Abstract
We introduce a blind spot method to create image changes contingent on eye movements. One challenge of eye movement research is triggering display changes contingent on gaze. The eye-tracking system must capture the image of the eye, discover and track the pupil and corneal reflections to estimate the gaze position, and then transfer this data to the computer that updates the display. All of these steps introduce delays that are often difficult to predict. To avoid these issues, we describe a simple blind spot method to generate gaze contingent display manipulations without any eye-tracking system and/or display controls.

The online access to gaze position data is delayed. This end-to-end sample delay includes the time taken for a physical event to be registered, processed, and made available online by the eye-tracking system, and the time needed to retrieve the data via Ethernet, USB, or analog ports
We use the natural blind spot observed in monocular vision as a self-generated saccade detector that produces an accurate intra-saccadic stimulus change
