OptiKey is a on-screen keyboard designed to be used with a low cost eye-tracking device to bring keyboard control, mouse control and speech to people with motor and speech limitations.
It works out of the box once you have your eye-tracking device installed and allows selections to be made using dwell selection, as well as physical buttons and assistive devices. If you do not have an eye tracking device you can also use OptiKey with a mouse or your webcam.
OptiKey can be used as an alternative to a physical keyboard, allowing user to type into any application. OptiKey can also automatically insert spaces between words and capitalise letters to increase your typing rate. You can even type whole words and phrases in a single selection by "swiping" or using "auto-complete".
OptiKey can replace your mouse, allowing you to click, scroll and drag with precision anywhere on the screen. The app was written to challenge the outrageously expensive, unreliable and difficult to use AAC (alternative and augmentative communication) products on the market.
