Some Cautions - LCT Eyegaze Edge User Manual

2.4.3 Some Cautions

Some computer programs and operating systems have commands that respond to combinations of
keyboard and mouse inputs. For example, mouse clicks may evoke different program responses if the
SHIFT or ALT key is held down when the mouse button is clicked. It is possible to perform most of
these operations on your PC through the Eyegaze Edge. To implement the above example, you would:
a) start in one of the Eyegaze keyboard screens,
b) set the keyboard shift state by visually activating the shift or shift-lock key (the shift key lights up),
c) go into the Mouse Control screen, and
d) activate a mouse-click key.
While it is possible to perform these kinds of operations intentionally, it is also possible to do them
unintentionally. To minimize such unintentional operations, it is recommended that you check that no
shift states on the keyboard screen are active before entering the Mouse Control screen. If any shift
state is active, i.e. if its key is lit up, looking at the key will turn it off.
