Do this well before you are ready to start running your experiment! Accessing scripts and data on other computers Working with the equipment does require some instruction and practice please read the information in Step 4, and contact Iris Mulders for a tutorial. Step 4 outlines how to perform camera setup and calibration. We also have a small flat external USB-screen that you can use to monitor the participant’s gaze during the experiment. The SMI setup consists of a laptop (running Windows 8), and the eyetracker itself, which is connected to the laptop through USB. The EyeLink Host PC and the Stimulus PC communicate over a (crossover, orange red ) ethernet cable using SR Research software. The Stimulus PC is a dual boot machine, offering a choice between Linux (default) and Windows 7. ![]() You can access the ILS Labs data server from the Stimulus PC. The Stimulus PC is equipped with two monitors, one in the operator room and one in the participant booth. Stimulus PC (in SR Research terminology: Display PC): controls the presentation of stimuli and the acquisition of subject responses.During an experiment, the EyeLink Host PC is controlled by the experiment program ZEP. The eye-tracking software on the EyeLink Host PC runs under DOS, and is rarely operated directly by the experimenter. ![]() Gaze positions are corrected for (small) head movements through the use of a target sticker on the participant’s forehead freedom of movement is 22x18x20 cm (horizontal x vertical x depth). It contains routines to calibrate a subject and to calculate, visualize, and store on-line gaze positions. The EyeLink Host PC was configured by the manufacturer, SR Research, and runs the software that controls eye tracking and data sampling.
