List of demo items: The SVB task is the setpoint generator and generates the velocity and position control More information. The Eyelink communicates via a high-speed ethernet connection with a separate computer Macintosh or PC that performs the stimulus display.
This is an example how to convert the horizontal and vertical traces from the UADC channels in Volt to screen coordinates in pixel. This section walks through a function that initializes the eyelink system. Extra Resourcess For examples of these methods eyelinnk action, check out an experiment on Voxel Tuning Functions. Subsequently you can resample the Hz Eyelink data to the Hz MEG data and append them in the same data structure for more convenient joint processing.
INI, or your presentation settings.
Professor Deepa Kundur Introduction Our project is intended to track the motion of a round. Footer Contact info sr-research.
Example programs are included with the toolbox distribution. For a technical overview about Eyelink characteristics look here The eye tracker can be used on itself, or in combination with other data acquisition techniques e.
Listing of the main toolgox available in the Eyelink data sample structure. Stops toobox eye-movement data. Getting started with SR-Research EyeLink eye tracker data At the Donders we have an Eyelink eyetracker that supports sampling rates up to Hz for monocular and Hz for binocular tracking.
The Eyelink Toolbox: Eye Tracking with MATLAB and the Psychophysics Toolbox.
Cognition and visual perception. The Eyelink Toolbox is compatible with both the first and second generation of Eyelink gazetrackers. Reports which eye s is being tracked. Vision Reseach, 42, The MathWorks. Heading detection with simulated visual field defects. See a list of Eyelink functions here.

Subsequently you resample or interpolate the data of one recording on the time axis of the other, and you append the tw. Freescale Semiconductor, I nc. By combining the information on eye-position with a measure of head-position, estimates of gaze position on a display can be obtained allowing the creation of gazedependent displays.
The powerful combination of the Psychophysics and Eyelink Toolboxes allows for a relatively fast and easy implementation of experiments involving eye tracking such as e.
In step 5, data recording commences. I have no clue where they would come from but suspect it to be a hardware glitch of the Bitsi box which links the serial port of the presentation computer with the input of the CTF and Eyelink acquisition systems.
