Switches, Keyboards & Other Accessories

Many students are unable to physically access toys, games, technology or their environment with traditional methods. Alternative keyboards, mice, trackballs, joysticks or switch interfaces may be necessary for access and independence. AAC systems offer a variety of alternate access methods.

Switch Access

A switch can be used to help interact with a battery operated or electronic device such as as toy, communication device, computer/tablet or environmental control.

Switches can be activated by any part of a students body hand, head, foot, eye blink, sip/puff, etc. Switches can be used as single point access or combined for multiple switch access.

Switches can be used for simple cause and effect, or complex communication and technology access.

Examples:

Keyboards, Mice & Stylus

External hardware, such as ergonomic keyboards, compact keyboards, enlarged keyboards, alternative mouse pointing devices, touch screens, stylus, joysticks, and single or dual switches may improve access to computer or tablet devices.

Examples:

Head Tracking & Eye Gaze

When using computer technology, head tracking and eye control systems measure head or eye positions and directly translate their movement into mouse movements. A quick nod of the head or blink of the eye and individuals with mobility challenges can navigate a computer completely hands-free. Head tracking and eye gaze can also be reliable methods allowing a user to access no tech and light tech communication systems.

The speed and ease of using eye gaze or head tracking by the student in comparison to many other alternative access methods should be considered in the decision making process.
