Each sample is a 1-to-1 translation of one of the sample C-programs which are shipped with the Optotrak API Download If you are interested in the Optotrak Eyeoink, I will be happy to send you a copy by email the Optotrak Toolbox is open software under the GNU general public license, such that it is free and you can modify the source code if you wish.

The response events however are not represented in the eye tracker dataset. The default EyeLink coordinates are mapped to a x display, with 0,0 at the top left andat the bottom right. A listing of the main commands and a short description of their function is provided in table 1. otolbox

This makes developing and testing an experimental script challenging, because if we litter our code with calls to Eyelink The Eyelink uses two high-speed cameras CCD sensors to track both eyes simultaneously. In step 6, current gaze position as communicated by the Eyelink is used to show a small dot on the display that moves with the subject’s gaze.

When the eye rotates away from the camera during viewing, the pupil seems smaller. Temporal integration of visual motion information: Evidence from response times. The Eyelink uses a PC with dedicated hardware for doing the image processing necessary to determine gaze-position.

For example, typical measurements of the standard deviations of gaze position at fixation are 0. These are just a few bits of code that I have found useful.
