CRS Saccade Detector v1

The CRS Saccade Detector is a real-time eye movement classification system for the Fourward Technologies DPI eye tracker. Its onboard data acquisition system acquires the horizontal and vertical eye position voltages at 1kHz and monitors the status of the Track and Blink signals. The eye movement’s classifications algorithm will determine if the input is a saccade or a fixation, and outputs a trigger to indicate which one has occurred. Separate output trigger lines are provided to encode the state of the fixation and saccade states.
