How can switches be used by people who cannot operate a standard keyboard or mouse?
When a person's mobility impairment prevents the use of a standard keyboard or mouse, using a switch may be a possibility. Switches come in a nearly limitless array and can be controlled with nearly any body part. Switches can be activated with a kick, a swipe of the hand, sip and puff by mouth, head movement, an eyeblink, or touch. Even physical closeness can activate a proximity switch. These switches work in concert with a box or an emulator that sends commands for the keyboard and/or mouse to the computer.
