Farming Simulator 17 will support head tracking via TrackIR, and eye tracking via Tobii EyeX. Once either or both of these devices are installed, starting up the game will introduce a prompt asking if you want to activate the tracking features. It’ll also be possible to activate or deactivate this feature from the menu.
TrackIR is a head tracking input device for PC which uses the data obtained from its infrared camera to allow supported games to know the real-time position and orientation of your head. Read up on more info about what TrackIR can do here.
When using TrackIR, Farming Simulator 17 is capable of supporting:
Yaw
Pitch
X, Y and Z axis
When activated, TrackIR tracks your head movements while driving a vehicle in first-person. Your head movements will move the camera accordingly. For example, turning your head in real-life to the left or right (yaw) will cause the camera to turn left or right.
TrackIR is able to track your head movements in 3D space. What this means is that you can move your head along the X, Y, Z axis and TrackIR will track it. For example, this would allow you to naturally move your head forward and up if you needed to look over your engine hood while working with a frontloader.
