In close cooperation with the Tobii developers we developed a tracker-plugin for the Tobii EyeX. The EyeX sends gaze-point data to FaceTrackNoIR and that data is "translated" into a headpose, which can then be used in games etc.
In addition to the headpose, the gaze-point itself is also relayed to FaceTrackNoIR and game-developers can use that, to (for example) use it to aim.
If you have questions regarding the EyeX tracker, please post them here: [discussion:tobii]
The EyeX reliably tracks the eyes of the user, in various conditions.
When the tracker is running, FaceTrackNoIR retrieves data from the EyeX device. The window indicates the presence of a user and the activity of the device.
Tracker algorithm: we have implemented 3 different algorithms to "translate" the gaze-point into a head-pose. Choose the one you think is best for you. The 3 tabs of the Settings-window contain specific settings per algorithm.
