Templates	Descriptions
SimplePicture	A simple EyeLink integration demo that records eye movements while an image is presented on the screen.
SimpleVideo	Simple video demo with EyeLink integration and animated calibration / drift-check/correction targets. In each trial eye movements are recorded while a video stimulus is presented on the screen.
Pursuit	A smooth pursuit EyeLink integration demo that records eye movements while a target moves sinusoidally across the screen.
MRIDemo	Simple MRI demo with EyeLink integration. 8 trials are presented in 2 blocks of 4 trials each. 500 msec fixation cross is presented, followed by a 7 sec image presentation, followed by a fixation cross for 2500 msec. Each trial consists of 5 pulses (the main pulse is every 5th pulse) of 2 sec each. A block starts with a drift-check followed by presentation of central crosshairs. Eye movements are then recorded while waiting for an MRI trigger (keyboard key 't' in this demo). The stimulus is presented when the trigger is received. Eye movements are recorded throughout an entire block rather than on a trial-by-trial basis.
FixWindowFastSamples	EyeLink gaze-contingent demo showing how to retrieve the latest gaze samples online. In each trial central crosshairs are shown until gaze is detected continuously within a central square window for 500 msec or until the space bar is pressed. An image is then presented.
GCFastSamples	A simple EyeLink gaze-contingent demo showing how to retrieve fast online SAMPLES. In each trial an image is presented with a red gaze-contingent dot overlaid on top. The dot's location is updated online based on the x, y coordinates of the latest gaze SAMPLE retrieved online.
GCLinkEvents	A simple EyeLink gaze-contingent demo showing how to retrieve online EVENTS from a buffer. In each trial an image is presented with a red gaze-contingent dot overlaid on top. The dot's location is updated online based on the end x, y coordinates of each saccade detected.
