Programmable keyboards offer the greatest flexibility for the young learner. Through the use of interchangeable overlays, a programmable keyboard can be quickly altered to meet the needs of the user and the learning task. An overlay is a sheet of paper or plastic with a graphic representation of a keyboard, a part of a keyboard, or symbols. The overlay slides easily into slots on a programable keyboard. Overlays can also be designed in drawing programs and printed out on your home printer using plain paper.
Customizable overlays are available from some software manufacturers.
These keyboards are available in larger size than standard keyboards. Can be set up with smaller keys for children with limited range of motion. Some can function as both keyboard and mouse. The rate at which key strikes are repeated can be lowered for children who dwell on a key, reducing unwanted numbers or letters. Miniature Keyboards are smaller versions of a standard keyboard.
