The full set of EyeLink functions are also available for programming specially customized experiments. The tool kit is made up of two high-level, shared libraries. 1. eyelink_core 2. eyelink_core_graphics The eyelink_core library implements all core functions. That is, all functions in this library, directly talk to.  · www.doorway.russage("TRIALID "+str(trialnum)) www.doorway.ruecording(1,1,1,1) www.doorway.russage("FIX1") tFix1On=www.doorway.rue() Gaze contingent programming.

C:\Program Files (x86)\SR Research\EyeLink\SampleExperiments\E-Prime The EyeLink COM Interface Manual documents all of the EyeLink functions available to E-Prime. It's important to note that the syntax for some of the commands in the manual may differ from how they are implemented in E-Prime, as E-Prime follows it's own syntax rules. EyeLink plus eye tracking system This manual is to provide information to work with the SR Research EyeLink plus eye track-ing system in Aalto Behavioral Laboratory (ABL). Further helpful information can be found from the Eye the EyeLink User manual and from the SR Research Support Sites (you have to regis-ter!). Some programming standards, such as placement of messages in the EDF file by your experiment, and the use of special data types, have been implemented to allow portability of the development kit across platforms. The standard messages allow general analysis tools such as EDF2ASC converter or EyeLink Data Viewer to process your EDF files.

available. The EyeLink is a truly multipurpose eye tracking solution. Each EyeLink configuration is unified by an identical application programming interface (API) and EyeLink Data File (EDF) output, allowing experimenters to seamlessly switch between data collection and analysis in. Figure 1 lists an example of a short MATLAB program that uses the Eyelink and Psychophysics Toolboxes to create a simple gaze-dependent display. Step 1 in the example is the initialization of the Eyelink, step 2 the opening of a graphics window using the Psychophysics Toolbox SCREEN routine. In step 3, Eyelink toolbox. A description of the most useful EyeLink routines can be found in this documnent. You will rarely need other functions than those listed. In addition, important commands that can be sent to the EyeLink tracker are also listed in that manual. These commands can be used for on-line configuration and control.
