Case Study

Onscreen Keyboards

An 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.

Examples

Here are some examples of onscreen keyboards. Some include speech output, which identifies the key when selected.

The Reach onscreen keyboard comes with over 100 different layout options and an assortment of Assistive technology options including: single switch scanning, text-to-speech, and word prediction (plus dictionary). Its "Smart Key" technology is an add-on program that incorporates next-letter prediction into the onscreen keyboard function. (Windows Only)

For example, load the onscreen alphabet keyboard:

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.

ScreenDoors 2000 acts just like a real keyboard typing directly into any application. The student simply points to a key and clicks, which acts as a keystroke; or she can use the dwell feature. It includes a list of predicted words that anticipate what you are typing to help speed entry. This software was licensed by Microsoft and forms the basis for the Microsoft On-Screen Keyboard included in every copy of Microsoft Windows 2000. (Windows)
