    Hi Tobii,
    I’m developing a C# application that requires the maximum pointing precision.
    I’m already using the “LightlyFiltered” option in EyeXHost.CreateGazeDataStream, but the filter isn’t sufficient.

    I noticed that the filter used by the EyeX controller driver smooths the eye movements very well, and reduces a lot of flickering noises.
    Is there a way to use that filter in C#, or is there some documentation that explains how to re-implement the algorithm?

    Thanks for your attention!
    Best Regards,

    Patrik [Tobii]

    Hello Nicola,

    The algorithms used in the Tobii EyeX controller is proprietary, so there is no public documentation of how it works.
    However, my colleague Robert discussed this in another forum thread which might be of interest to you.

    There is also an implementation of a smoothing algorithm in the Spotlight demo that is part of the Tobii EyeX SDK for Unity.

    Best regards
