Calculate Coordinates for Calibration Targets
Use this calculator to determine coordinates for calibration targets and check whether your stimuli / screen fit within the trackable range of your EyeLink eye tracker. For calibration coordinates just enter your screen resolution and select the relevant calibration model. The calibrated area can be adjusted, either with an offset grid with a set pixel height and width or by adjusting the values for proportion and corner correction (default values are used). To check whether your calibration targets / stimuli / screen fit within the trackable range of your eye tracker (cyan box), select Yes on the Trackable Range Check, enter your screen distance and dimensions, and select your tracker / mount combination from the dropdown. The calculator returns the calibration target coordinates as well as the appropriate screen distance or the stimulus dimensions for your set-up. It will also warn you if your current screen dimensions exceed the trackable range of your system.
Note: the connection to the calculator may close after a few minutes of inactivity – just refresh the page and it will be back!
