    I am trying to figure out the angular values for pitch, yaw and roll that I get from the Tobii interaction head pose stream using the .NET SDK. By experimenting, it seems that multiplying the pitch, yaw and roll components of the head pose vector by 60 gives the correct angle (since roll is reported to be ~3.0 when my head is upside down in front of the tracker).
    Can someone confirm that this is correct and also applies to pitch and yaw?

    Hi @hestelandsbyen, Within the Tobii Core Interaction API, angles are returned as radians.

    Therefore multiplying by 60 approximately means (180 / PI which is around 57) converting from radians to degree.
    The correct behaviour should be multiplying with 180 and dividing to PI after that.

    Please let us know if we can be of any further assistance.
