The Tobii Eye Tracker Game Hub plugin now supports X-Camera natively. You need to run version 3.3 or higher of the Tobii Game Hub and install the Tobii Game Hub X-Plane plugin.
The new Tobii X-Plane plugin will automatically detect when X-Camera is installed and enabled on an aircraft. When X-Camera is enabled the Tobii plugin will send any head/eye tracking data to X-Camera. You can enable this head-tracking data on any camera by checking the TrackIR option on that camera’s setting.
