to control. When you type on a Computer Access keyboard, the characters you type will appear at the
top of the Eyegaze keyboard screen as well as into your selected program on the computer you are
interfacing. As you are writing a document it is not necessary to continuously look at your computer's
monitor to review the text. The last 8 to 10 lines you have typed will appear above the keyboard display
on the Eyegaze control screen.
In the Computer Access program, the various special keys (Function, Control, Alt, Command, etc.) on
the Eyegaze keyboard will take on the meanings defined by the application program you are running on
your computer.
Looking at the "Out" key brings up the Keyboard Control screen, which allows you to select alternative
keyboards, adjust the gaze duration for faster or slower key activation, print, clear the screen of text or
exit back to the Main Menu. The Keyboard Control screens on the Computer Access program are
operated the same as those in the Keyboard program. (See Section 2.3.2 "Keyboard Control Screen".)
The "Clear" key will clear the text off of the Eyegaze screen, but not off of the screen on your computer.
The "Print" key will print the text as it appears on the Eyegaze screen, not as it appears on your
computer. (Use the print command for the program you are running on your PC or Mac to print its text).

2.4.1 Mouse Control in the Computer Access Program

Visual mouse control of your PC or Mac is done through the
Mouse Control screen. The user brings up the Mouse Control
screen by activating the "Mou" key on any one of the Eyegaze
keyboards in the Computer Access program.

Positioning the Cursor
The cursor on your computer's monitor is put into motion by selecting one of the eight arrow keys
labeled "Move Mouse" on the Eyegaze system's Mouse Control screen. The direction the cursor will
move (up, down, right, left, and four diagonals, which are not labeled) is determined by which key you
activate.
There are two ways to control the cursor motion: the Speed and the Step modes. A user switches
between the Speed and Step modes by activating the Mode key on the Mouse Control screen.
Activating the mode key toggles the mode between Speed and Step modes. The name of the mode
that is active at any time is displayed above the Mode key.
Speed Mode
To put your computer's cursor in motion, look at the Move Mouse key that corresponds to the direction
you want the cursor on your computer to go. When the directional key is activated it will turn blue.
When it turns blue, look over at your computer's monitor and watch the cursor until it gets to a point
where you want it to stop. Immediately look back at the Eyegaze screen to stop the cursor. The entire
Eyegaze screen has become a giant STOP button. The cursor will not move again until you activate
another arrow key.
To adjust the speed of the mouse cursor, select one of the six keys labeled "Cursor Speed / Step Size."
Key 1 gives the slowest speed, allowing the cursor positioning to a single pixel. Key 6 gives the fasters
speed, allowing the cursor to traverse the entire screen in little more than a second. After selecting the
cursor speed, the value for the speed remains the same until you change it by selecting another Cursor
