TouchFree Switch, by the IBM subsidiary Edmark, enables the disabled to use computers and surf the web. This “no-touch” device pairs a digital camera with switch software to let users who are unable to use a traditional mouse trigger a mouse click.

TouchFree Switch can recognize almost any movement as a mouse click—from a head nod to a toe tap, according to Edmark. After setting a designated movement for the camera to detect, the user watches a cursor on the monitor float from icon to icon. When the cursor gets to the right icon, the student makes the designated movement and the computer makes the selection.

TouchFree Switch, which installs quickly, comes with switch software and a high-quality USB camera. It is compatible with both Macs and PCs. The suggested retail price is $249.99
