Computer access devices allow people who have problems using a conventional keyboard or mouse to access the computer. Adaptations to assist with computer access can include the following:
ALTERNATIVE MICE/POINTERS: Alternatives to a standard mouse include smaller mice, touchpads, roller and track balls, joysticks, head/eye controlled computer access, ergonomic mice and more.
For children with decent vision and good control of the head, a head mouse is sometimes an option for accessing a computer. This method uses movements of the head to move the cursor with a small tracking dot on the forehead and a camera to track the movement of the dot. It is successful at sensing very small head movements. A head mouse can be added to a wide variety of communication systems as well as regular computers.
Light pointers and infrared pointing devices can also be used with some people who have adequate head control. These are worn on the head, like the head mouse, but transmit a beam of light to the equipment being controlled instead of using a camera. The computer or responds to the light beam as if the keyboard has been touched.

KEYBOARDS: “Sometimes all that is needed to give a person with a physical disability direct access to their computer or communication aid is to adjust the settings for the keyboard, to place a keyguard over the keys, or to substitute a special keyboard for the standard one. Most computers and many communication aids allow you to adjust the keyboard response time to make it easier for the person using it to be accurate. A keyguard, usually made of plastic or metal with holes drilled in it corresponding to the keys and fixed over the keyboard, might allow an individual to use a standard keyboard without accidentally hitting the wrong keys. Different types of keyboards are available. Expanded keyboards have larger, more widely spaced keys. There are also ergonomically designed keyboards which are easier to use for people using only one hand or a head pointer.”
