Adjustable Tables
Here are some of the lower tech methods/strategies for inputting to standard computer systems.
Sometimes a modification to the physical layout of the computer can enable a user to effectively access the standard keyboard, especially if keyboard modifications like Sticky keys or a slowed response rate are used to compensate for coordination difficulties. Positioning the keyboard on an angled, height-adjustable keyboard table, providing support through armrests or a wrist rest can all help stabilize the limbs to maximize accuracy. Positioning the keyboard at foot level is more functional for some users with better control of their lower extremities than the upper
Some users with poor motor control of the arms can use a stick held in the mouth or attached to headgear to depress the keys of a keyboard, with Sticky keys to help with depressing multiple keys sequentially. Keyguards are metal or plastic grids over the keyboard that allow a user to slide across them and then push a digit or stick down the holes to depress a key, preventing inadvertent hits. They can obscure the view of the keyboard and also are increasing ly hard to purchase, due to the plethora of keyboards available.
Other users who benefit from wrist rests, adjustable keyboard heights and ergonomic positioning are those with Repetitive Strain Injury(RSI). RSI is an occupational hazard of our times, forcing some people to change types of work or limit keyboarding time. Although some can modify their work station and work styles to continue, others use Voice Recognition for keyboard and mouse input.
