bulletthat performs the gaze cursor generation


The Gaze Overlay accessory for the EyeLink system converts the graphics from the stimulus computer monitor to a NTCS or PAL video stream. A cursor is drawn on the video representing the participant’s point of gaze on the display.

This option is used to provide gaze position information on a dynamic stimulus display, like a web browser, other computer applications, digital video, or DVD movie. The video signal is then typically saved onto a VCR or DVR recorder, but can also be saved to a computer using a S-Video to DV-AVI converter.
