3) Activate the Delete key again. The file is now deleted, and the screen reverts to the Retrieve

screen.

If you start the delete procedure by mistake, or if at any point during the procedure you decide not to

delete a file, you can stop the delete procedure by looking at the exit key. Also, any variation from the

above procedure will cause the screen to revert to the Retrieve mode without deleting a file.

Clear/Restore Key

To erase all text from the screen, look at the "Clear" key on the Keyboard Control screen. When the

Clear key is activated it will change to "Restore". If you accidentally clear the text, or if you exit from the

Keyboard program without saving the text you just wrote, it is possible to restore that text. Whenever

you clear the text or exit the Keyboard program, it automatically saves the text in a special backup file.

When the key is in the "Restore" state you can bring back that last unsaved text by looking at the

Restore key.

Gaze Duration Keys

To make the speed of key activations faster when you type, look at the "down" key. Each time the key

is activated it will decrease the time you must fix your gaze on a key by .03 seconds. To slow the speed

of key activations look at the "up" key. Each time it is activated the amount of time you must look at a

key to type will increase by .03 seconds. An assistant can permanently change the default gaze

duration for the Eyegaze keyboards by using the ECS Settings program. (See "Special Gaze Duration:

in Section 6.7 "Setting Up the Keyboards".)

Type Key

Looking at the "Type: key will bring the selected keyboard up on the screen.

Print Key

If you have a printed connected to your Eyegaze Edge, activating the "Print" key will print out the

document you've been typing.

Speak Key

Activating the Speak key on the Keyboard Control screen brings up a special speech control screen.

Looking at the "Speak full text" key will verbalize the entire text. "Speak paragraph" will verbalize the

paragraph where the cursor resides. The arrow keys move the cursor up, down, left, and right. The

Home key (labeled Hom) moves the cursor to the start of the paragraph. The "End" key moved the

cursor to the end of the paragraph. "Page up" (labeled PgU) and "Page down" (labeled PgD) move the

cursor up or down 6 lines.

Speech Mode Key

The Eyegaze keyboards have three Speech Modes: "Off," "Character," and "Word". In the "Off" mode

the speech synthesizer remains silent until the Speak key is activated. In "character" mode the

synthesizer verbalizes each letter as it is typed. In "Word" mode it speaks each word as it is typed. In

the "Word" mode, the speech synthesizer assumes you have finished a word when you type a space or

punctuation mark. These settings are rarely used. An assistant may permanently change the Speech

Mode by using the ECS Settings Program. (See "Default Keyboard" in Section 6.7 "Setting Up the

Keyboards".)
