Sorry for late answer, the complete specification is not ready yet but we got some initial figures for the track box (or actually, it’s a frustum)
The working distance of the EyeX is 45-80 cm (18-32 in)
At 70 cm (28 in) distance, the head movement “plane” is 48×39 cm (19×15 in)
The numbers are specified parallel/orthogonal to screen surface, assuming eye tracker is at 20 degree angle to screen.
