    I created a few demo using the Tobii eyetracker.

    The first one is for viewing images using the Cooliris browser plugin:


    Then, I turned the same idea into a movie trailer browsing app:


    Next, I wrote two browser plugins for text translation and currency conversion:



    Hope you like it, any comments and suggestions are welcomed 😀



    I would suggest to translate the words in a little square above the original, so that you don’t lose the original word and learn it better.

    Are those app available ? and source code ?
    I might want to improve the text reader one.

    Good work.

    You can find the source code here:


    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 I include a screenshot of the eyex version in the dropbox folder. (Using the latest eyex software will break the code)

    Hi Cheng Guo,

    Thank you for sharing the code! To make it compatible with EyeX 1.X, all you need to do is to replace the Tobii.EyeX.Client.dll with the 1.X version, included in the EyeX SDK for .NET 1.0. No other code changes should be necessary.

    Thanks for pointing that out Rob!
