Chapter 5 Using Overlay Keyboards

Sticky Keys. Most programs have Sticky Keys for people who cannot hold down two keys at once: the Shift or Control key is pressed first, then a letter key pressed next (see Chapter 3 Accessing the Keyboard for a full description of sticky keys).

Mouse Pointer Control. Control of the mouse pointer is a very useful feature as many pupils who have difficulty with a standard keyboard also have problems with a mouse.

Auditory Feedback. The keys on an overlay keyboard do not move or click when pressed so there is little feedback that a key has actually been activated. Most keyboards or programs give an auditory beep to confirm when a key is pressed. This is helpful for users with visual impairments, learning difficulties, or physical access problems.

Digitised sound. Some programs let you use the keyboard to play back digitised recordings or sound or speech.

Speech Output. Programs which can generate synthetic speech, instead of, or as well as, text can be useful to support literacy and writing or for interpersonal communication.

Keyboard Response. Sometimes it is important to be able to adjust the response of the keyboard (see Chapter 3 Accessing the Keyboard for a description of the various adjustments), so the table shows which facilities are offered with each program.

Print-out Overlay. Programs with facilities for creating and printing paper overlays ready to be used with new overlay files can save considerable time and effort.
