OptiKey is an assistive on-screen keyboard which runs on Windows. Launched last week as a free, open-source service, OptiKey pairs with third party eye-tracking devices to help those with severe motor or speech limitations to communicate more effectively.
The motor neuron diseases (MNDs) are a group of progressive neurological disorders that destroy motor neurons, the cells that control essential voluntary muscle activity such as speaking, walking, breathing, and swallowing.
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease and Charcot disease, is a specific disorder that involves the death of neurons.
The software helps users with disorders such as ALS or MND to control digital mice and keyboards and to speak via their Windows-enabled devices.
The on-screen keyboard also works with physical button controllers, other assistive devices, and typical computer mice. It does pretty nifty stuff like clicks scrolls and drags.
