I am using EyeX tracker together with EyeX SDK for a school project. The display in use is custom made, and is curved. Therefore, the Engine cannot properly setup the display: the illustrated eyeX tracker is larger than the actual device.
Later when I try calibrating, the engine says cannot detect my eyes even after I popped all the dots. My guess is that the computed calibration is not valid. I tried running the EyeX SDK samples without calibration, and no data is coming in.
My application is very simple. I only need to detect where the gaze is on the screen. As long as I can get the tracking data, I should be able to do my own calibration.
Can you please help me out here?

Hi @xtsun, unfortunately the EyeX SDK does not allow for custom calibrations and we are quite specific in our requirements for screen dimensions (and form).
The best I can suggest is that you calibrate on a normal screen of similar size to your curved one, then replace the monitors out. You will not get great accuracy, but perhaps this is enough for your needs?13/10/2016 at 16:07 #5825Xuetong SunParticipant
Thanks for the reply and suggestion. I managed to calibrate on the curve screen after all. It took me a while, but I pulled the eye tracker away from the screen, and pretended it was mounted on an imaginary screen.
Thanks for the help.
