Floating-point eye event with floating point time.
The EyeLink tracker analyzes the eye-position samples during recording to detect saccades, and accumulates data on saccades and fixations. Events are produced to mark the start and end of saccades, fixations and blinks. When both eyes are being tracked, left and right eye events are produced, as indicated in the eye field of the FEVENT structure.
Start events contain only the start time, and optionally the start eye or gaze position. End events contain the start and end time, plus summary data on saccades and fixations. This includes start and end and average measures of position and pupil size, plus peak and average velocity in degrees per second.
