what is switch access

Switch access is the use of one or more switches to operate computers and other devices, primarily used by people with severe physical or cognitive impairment. A switch is an assistive technology device that replaces the need to use a computer keyboard or a mouse. It may allow users to control a computer, power wheelchair, video game console, tablet, smartphone, toy, and a variety of other electronic devices. Switch Access can be helpful if you can't interact directly with your device, and it is available for Android devices, allowing users to interact with their devices using one or more switches instead of the touchscreen
