Using Target Dots
A package of pressure-sensitive, reflective target dots was included with
your ChatPoint. Peel a dot from the sheet and press the dot onto the
user’s forehead or eyeglass frame.
ChatPoint calculates how light reflects off the dot to detect the user’s
head movement. The on-screen pointer moves with the user's head
movements.
Setting Dwell Time
Dwell time is the time required to make an activation. For example, if
dwell time is set to 1 second and the user leaves the pointer on a button
for 1 second, ChatPoint activates that button automatically.
To set the dwell time, choose
Dwell Time

Settings screen. The Dwell Time window opens.
