We all love free stuff right? OptiKey is an open sourced, eye controlled, on-screen keyboard, free forever! It works with an eye tracker like Tobii Eye Tracker 4C, TheEyeTribe and EyeTech TM5 mini eye tracker, etc. This brings 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 allows selections to be made using dwell, as well as physical buttons and assistive devices (such as Glassouse, or other assistive switches). If you don’t have an eye tracker, don’t worry! You can still use your mouse or even your webcam. Also, OptiKey can replace your mouse allowing you to click, scroll and drag with precision anywhere on screen. Want to have a go? Download it here. Here’s a video of it in action.
