Dear Agostino,

This is Owen. I am studying electrical engineering. I got a final year project to analysis the effectiveness of UHD display by using the eye tracker. May i know the sequence for running the matlab files as i am not good at matlab, many thanks.

Sincerely,
Owen

Hello,

I have encountered an error message. I do not know the sequence with which I need to run these matlab files. When I run EyeXMatlabServer located within matlab_server folder of the project file, I get the error. What should be done to fix it ? Even if i download and reinstall it again, I am getting the same error.

-The *CalibrationProcedure* function is the core of the calibration procedures, as described in Sec.~\ref{subsec:calibration*. The function takes as input an Nx2 vector containing the N normalized coordinates (X and Y) of the targets to be used for calibration, and returns two structure, for the left and the right eye, containing the calibration fit functions for the X and Y gaze estimation. In the present work we investigated whole screen device calibration, but the procedure can be easily tuned to the requirements of different experiments or applications. For instance, in the vergence experiment presented in Sec.~\ref{subsec:vergence*, the relevant portion of the screen was a central area, only. Accordingly, the calibration procedure was modified and consisted of eight targets positioned on a circle of radius 2.5^\circ, plus one in the exact center of the screen.

 ##Sample Code
-The script *EXAMPLE_SALIENCY* is the MATLAB code used for the measurement of visual exploration eye movements on an image, presented in Sec.~\ref{subsec:saliency*. After having activated and initialized the Tobii EyeX, a window is opened via Psychotoolbox with a gray background. The window is first used to perform a 9PC, and next to display the image to be explored. The left and right eye position measured during the experiment are used to compute a bidimensional histogram from which we obtain the salient points on the image (see Fig.~\ref{fig:sal_ex*).

 This code is provided as an example that can be easily modified by a user for their specific purposes. Regarding the calibration, the target position can be easily modified in the script, in order to take into account the different requirements of the experiment. Likewise, the code relative to the eye tracker is conceived to be easily integrated in a pre-developed code.
