keyboard displays a picture of a keyboard on the computer screen. It can be one
solution for students able to control a mouse or pointing device, who need to
see the keyboard directly on the screen. The student moves the pointer (with a
pointing device, etc.) to the letter/command of choice and then clicks
to select it.
Some programs arrange the keys in alphabetical order. Others
allow the student to design her own layout or allow the student to type words
or give multiple commands by activating a single "key". The onscreen
keyboard can do everything the standard keyboard/mouse does. Onscreen keyboards
can often be moved or re-sized. Frequently they offer other features such as speech
output or word
Dwell selection - Suppose a student
can control the mouse, but has trouble clicking it. Dwell selection allows him
to leave the pointer on a key for a certain period of time, at which point it
is automatically selected.
Here are some examples of onscreen
keyboards. Some include speech output, which identifies the key when selected.
