    Greetings,

    I have some doubts regarding the data output in Unity Tobii SDK, please your help:

    – In the Gaze data there are 2 eye data. What is the difference between the left and right data with the “original gaze” left and right data?.

    – The validity field changes sometimes with the value “true” or “valid” so I don’t understand this little differences.

    – What´s the difference between GazePointInUserCoordinates and GazeOriginInUserCoordinates?

    Finally, is there any documentation regarding the type of data ?

    Data:

    <GazeData TimeStamp=”2099172947″>
    <Left>
    <GazeOriginInTrackBoxCoordinates Value=”(0.60898540, 0.52333770, 0.41998410)” Valid=”True” />
