People with limited coordination or someone using a pointing device can use a keyguard as an aid to operating a computer. The keyguard is made of hard plastic and is perforated with holes for some or all keys on the keyboard. This makes it easier for the user to avoid striking unwanted keys.
The keyguard is place on top of the keyboard and fills up the spaces between the keys. This helps prevents the user from unintentionally pressing multiple keys. Slots are created by the holes in the cover which allow the writing fingers to dip down onto the individual keys. This gives the users extra grip when they press a button and helps them to write when hand tremors make it difficult.
Secure hand rest
The keyguards are available with varying dept of slots and diameters. The keyguards acts simultaneously as a secure hand rest. They are usually made from plexiglass, can be place easily over the keyboard and cam also be easily removed again.
Big – and small pad keyboards
For people with impaired mobility or lack of accuracy of the key functions the use of big pad or small pad keyboards is often suggested. Big pad keyboards are available in various sizes, the buttons are bigger and sunken, and there is also generous space between the keys to avoid errors. Even small pad keyboards with generous spacing make it easier to tap the keys, for users with a lack of fine motor skills and also provides stronger support.
Micro keyboards for users with limited movement radius
Micro keyboards are also available for people with muscle weakness or a severely restricted movement radius. With flexible keyboards the key interface is variable, in the number, size and arrangement and thus adjustable to the individual needs of the user. For people that can only work with one hand, there is a one-handed keyboard. The size is geared according to the users range of movement.
