Thanks Jeff. Well spotted! You can configure a few things about a fixation in OptiKey - how long a user must fixate on a key before a selection begins (the lock-on time), how long it takes to complete, and how long a partial selection will hang around if your attention moves away (the time to live).

I am thinking about adding more settings to control the behaviour of the progress animation - Martin (and the COGAIN book) suggest a shrinking target to draw the user's eyes towards the centre of the key. I might add settings to control the "initial size" and "final size" of the animation.

I'm also interested in adding an EEG selection trigger, as per the 'Brainwriter' by Not Impossible Labs.

Awesome.
I love how the visual gaze accumulation progress that you have achieved for each target stays for a bit as you move around.

OptiKey - full computer control and speech with your eyes

OptiKey is an assistive on-screen keyboard which runs on Windows. It is designed to be used with a low cost eye-tracking device (including TheEyeTribe) to bring keyboard control, mouse control and speech to people with motor and speech limitations, such as people living with ALS / 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.

OptiKey was written to challenge the outrageously expensive, unreliable and difficult to use AAC (alternative and augmentative communication) products on the market. It is, therefore, fully open-source and free. Forever.

Download it, read about, check out the source code (C#) and watch the demo video at http://www.OptiKey.org
