The Eye Tracking Workshop: The second session

The 'Attention, Computational Models and Eye Movements' Research and Study Group presents the results of the second session of the two-day Eye Tracking Workshop. Participants were introduced to gaze contingent methods in eyetracking.

One powerful method for eye tracking experiments is 'gaze contingent' eye tracking where the participant's display is changed based on her current gaze position. Modern eye trackers provide gaze position information at better than millisecond resolution and latencies of less than 2ms. Paired with fast display monitors (~144 hz) we can create experiments that adjust the screen based on real time feedback of the eyes. For example, we can show only a small portion of the screen that is covered by the participant's foveal vision and black out any part of the image in the parafoveal areas. This allows us to separate the contributions of overt and covert attention to a task. Other uses include testing saccadic suppression of displacement and to simulate the visual fields of patients with hemianopia.

This workshop discussed both programming techniques and theoetical uses of gaze contingent displays.

The workshop was held by Dr. Joe MacInnes (Associate Professor, School of Psychology).

The event took place November 30, 2017, at 4/2 Armyanskyj per., room 414.
