Can we get gaze information in pixels with .Net Tobii.Research ?

Can we get eye movement information in pixels with Tobii.Research .Net?
Or (1920×1080 screen) how to calculate the position of the photo according to tobii coordinate system (between 0,0 and 1,1)?

Hi @akingunduz, thanks for your query. The gaze data will is displayed by default in co-ordinates normalised with reference to the current screen in use. (0,0)->(1,1)

What this signified for example is that the point value (1,1) would represent pixel co-ordinates (1920,1080), (0.5,0.5) would be (0.5*1920,0.5*1080)=(960,540), etc

So hopefully you can see the simple conversion necessary of multiplying the normalised units by the screen pixel dimensions should you want the gaze data in absolute pixel format.

Please let us know if we can be of any further assistance.

Hi @akingunduz, I trust that my previous response to your query was understood? Please let me know otherwise… thanks.
