Tobii EyeX tracker

Info:

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.

Advantages:

The EyeX reliably tracks the eyes of the user, in various conditions.

Downloads:

The current version of the TobiiTracker is part of the free PluginPack that's available for download from SourceForge. You can find the latest version here:

Settings:

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.

• Absolute View: the gaze-point is converted into absolute Pitch and Yaw values using curves.
• Freelook 360: the coordinates of the gaze-point are compared to the center-coordinates. The Yaw and Pitch of the headpose are calculated using this "delta" and the settings Deadzone and Sensitivity. This algorithm is most suitable for "cockpit-games".
• Extended View: the gaze-point is also used to pan Pitch and Yaw, but the range is limited compared to Freelook. This mode is best used for FPS games.

Known Issues and limitations:
