Onscreen KeyboardsAn onscreen 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 mouse, touch screen, trackball, head 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 prediction. 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. ExamplesHere are some examples of onscreen keyboards. Some include speech output, which identifies the key when selected. Discover: Screen (Madentec)

If you start to type "lucky", when the letter "L" is typed, not only does REACH start predicting the word you are typing (word prediction starts predicting words that begin with "L"), but Smart Keys starts predicting the next letter.
