Eye tracking software for sufferers of ALS/MND can cost tends of thousands of dollars, so Redditor spent 3.5 years of his spare time writing a free & open-source alternative - meet OptiKey (C#, Rx, WPF)

OptiKey is an assistive on-screen keyboard which runs on Windows. It is designed to be used with a low cost (around $100) eye-tracking device to bring keyboard control, mouse control and speech to people with motor and speech limitations, such as people living with Amyotrophic Lateral Sclerosis (ALS) / Motor Neuron Disease (MND).

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 use OptiKey with a mouse.
