Access Methods
An access method (or selection technique) is how you will control your device. You can select
Touch, Headpointing, 1-Switch, 2-Switch, and Joystick. Any Joystick other than a USB
joystick will need an adapter.
Access Methods and their options are in the ACCESS METHOD MENU in the Toolbox.
Warning! All access methods require a positioning analysis to prevent repetitive stress
injuries.
The Access Methods
Touch:
You must be able to touch the keys on the screen to activate them.
You make direct selections on the keyboard by pressing on the keys you want with your finger
(or with the eraser end of a pencil or some "point and press" device). You can use Touch with
any screen.
The touch screen is hard plastic. Be careful not to scratch it with your pointing device.
Headpointer
Madentec's Tracker
™
headpointing technology is already integrated into your device. If you
purchase the headpointing option the only "headpointer" you will need is the reflective dot that
came with your device. You stick this small dot on your forehead, on the bridge of your glasses
or on any moveable location on your body where the headpointing sensor on the front of the case
can see it. As you look at the keys you want the headpointer to activate, you must keep the
reflective dot within a 30-35 degree angle of the sensor. You should be seated within a 1-3 foot
range of your device.
When everything is working correctly, an LED inside the dark window on the top front of the
case will light up. The LED is centered on the left side of the IR window. If the LED does not
light, make sure your head, or whatever part of your body you used for the reflective dot, is
within the 30-35 degree range of the sensor. Also make sure you are seated neither too far away
from, nor too close to your device. Move the dot around and up and down until you see a hand
appear on the touchscreen and the LED stays on.
1-Switch Scanning
Use a single switch to scan to any key on the screen. Choose to scan by rows and columns or by
columns and rows. Plug a single switch into either the SWITCH A or SWITCH B jack on your
device.
