Smartbox Grid Pad Manual page 53

Setting up your Grid Pad for eye gaze access
It is important to have your Grid Pad set up securely for eye gaze
access. Position the device between 40cm and 75cm from your
eyes, using either the built-in stand or mounted on a stand that
suits you. The best position may vary depending on the camera
you are using. (See the section Mounting your Grid Pad section of
this manual for more information on mounting options).
