Hi all
i was wondering if anybody could tell me how the eye coordinates are reported in the gazedata file.
Mostly i am not sure what the reference is. Are they expressed in pixel locations (although they do no look to be to me)?
The reason why i would like to know this is to be able to run some post hoc analysis on specific portions of the stimuli in the screen
thanks
giulia

Hello,
Yes, the coordinates reported in the gaze data file will be in pixels. They will always be relative to the resolution of the Display device in E-Prime. So if you are using 800 x 600 any gaze points to the center of the screen would be reported as 400, 300. E-Prime calculates this for you automatically and just checks the resolution bein used at run-time.
