There are two pieces to it. The EyeTranslation is a chrome plugin which highlights every word when the mouse cursor hovers over it. The EyeXoverlay is a C# code that bind the mouse cursor movement to your eye movement. The mousekeyboardlib is a util lib that allows me to control the cursor easily.
The C# code works only with EyeX version 0.10.0.1889. I include a screenshot of the eyex version in the dropbox folder. (Using the latest eyex software will break the code)
