Advanced Settings (found under Customize Eyegaze Settings Menu)
Fixation Window X Fixation Window Y
These two options refer to the point at which you stop looking at the screen in general and begin to fixate on the area where you want to make a selection. Think of it the fixation area as a window that contains the key you want. You may need a big window to look in or a small one. Fixation Window X is the horizontal axis and Fixation Window Y is the vertical axis of your window.
The defaults give you a very small window. This is because the smaller the fixation are (or window), the more precise your movements can be. However, if your gaze is very jittery, you will need a larger window. If the defaults are not working for you, experiment with these two options to see if they help you.
Camera Angle (Deg)
This allows you to move the eyegaze unit up or down 5 degrees.
Y Camera Distance (mm) Z Camera Distance (mm) Screen Height (mm) Screen Width (mm)
IMPORTANT NOTE: Do not change these four options unless you have been instructed to do so by a PRC Service Technician.
Default Geometry
This sets all the options in this menu back to their defaults.
