I am looking for a couple of technical information which could not find,
What are the following technical information about the tobii EyeX and REX?
-Gaze position accuracy ?
-Spatial resolution (RMS) ?
-Head movement velocity?
BTW, are the devices binocular ?
REX advertises it has embedded hardware, how different that embedded hardware is with EYEX hardware and does it add to the robustness of the device?
