Released last week as a free, open-source service, OptiKey pairs with third party eye-tracking devices to allow those with severe motor or speech limitations to communicate more effectively. The software enables users with disorders such as Amyotrophic Lateral Sclerosis (ALS) or other Motor Neuron Diseases (MND) to control digital mice and keyboards and to speak via their Windows-enabled devices.
OptiKey also works with physical button controllers, other assistive devices, and typical computer mice. It does pretty nifty stuff like clicks scrolls and drags and will work with any Windows application.
