Hi,
I am trying to understand how to find the XY co-ordinates on screen.
I use a single hd camera and one IR light source to make a remote eye tracking system. I am using an open source (Haytham) software, which is an extension of ITU gaze tracker, to track the pupil movement.
I simply use a PDF document to read and test the software. The software dose not identify the gaze point on screen, say, the exact word location where I am looking at. Rather it produces only XY coordinates for pupil movement (of the video recorded by the camera) displayed on screen. I have attached a spreadsheet that gives the data of eye movement in the video.
I would like to find the co-ordinates of the words where I am looking at, on screen so that I can find the saccade eye movement pattern. I would like to know, is it possible to find the original gaze point on screen using the coordinates recorded by the software?The project mainly depends on this data, so if I get to know about some ideas regarding this, that would be really very helpful with my progression.
Thank you
