Tobii 4c eye traking

[Farlerion]

Hi all.

 

A few months ago I bought this peripheral.
I really like how it works, traking the eyes and the head but I have a doubt. 
I can't zoom in or out or lift my head or duck it.

 

To play the game I must use the software of tobii and Vjoy, for complete compatibility.

Could someone help me set the zoom?

 

In FAQ of Tobii say this:

Q: What sort of head tracking does it support?
A: Position and rotation.

• Position: X, Y, and Z. 
• Rotation: X, Y, and Z (pitch, yaw, and roll).

 

Thank you

 I use the in game zoom : numpad + and numpad - mapped to my joystick. Also Inser, not a true zoom but it helps.
