Dear,

Thanks for the answer! The purpose of my thesis is to make a wheelchair with eyetracking for paralyzed persons for example. So simply said: if the person looks to a certain point, the wheelchair has to move in that direction.

But if I understand it correctly, the point where you are looking at, has to lay at a fixed distance. So my idea now is to make a construction around the wheelchair: you have the eyetracker at a distance of 30 cm above the legs and you have an iron bar with a height of 5 cm just above the eyetracker. This bar has a width of 67.8 cm, which gives us a diagonal of 68 cm ( = 27″). If the person is looking at the bar, I can get the coordinates from the Tobii software. From these coordinates, I can derive in what direction the wheelchair has to move. So the person has to look at the bar to steer the wheelchair.

Do you think this is possible?
