This is quite an old post however I can’t figure out how to make a new post on the forms so here shall do, it seems you guys have removed tobii stream engine access to tobii eye tracker 5, is there anyway to access this my use case is I want to develop my own personal software for best possible accurate gaze tracking. The reason I need the SDK is to implement smoothing features, hybrid modality, predicative movement and the like, also to access the raw gaze data.
