Bah écoute je viens de regarder, j'ai trouvé une info sur un wiki de TF2 (hi grostom) : wiki.teamfortress.com/wiki/Oculus_Rift_User_Guide
0: Aiming and steering are coupled on the rift. The mouse steers as well. This is a good mode for use with a control pad.
1: Aiming with the rift, steering with the mouse. This mode may be buggy and "drift" after a while.
2: Steering has a dead zone. Inside the dead zone you aim with the rift and the mouse aims and steers simultaneously. Outside the dead zone aiming and steering are coupled for both the rift and mouse.
3: Steering with the rift, aiming with the mouse inside a dead zone. Outside the dead zone the mouse steers as well.
4: Relative camera control with the rift (no influence on aiming or steering, relative to your character's facing direction). Mouse is as mode 3 combining aiming and steering with a dead zone.
5: Absolute camera control with the rift. Your reference is not tied to your character's orientation so steering with the mouse does not influence the direction in which you look. You must actually turn around to see where you're going if your character turns around. Aiming and steering is coupled and controlled with the mouse. This mode should play well with a wireless controller and could give you a good sense of direction within the map.
6: Relative camera control with the rift. Aiming and steering is coupled and controlled with the mouse.
7: Rift input is not used, so you only get stereoscopic vision. Aiming and steering is coupled and controlled with the mouse.
8 or higher: If you accidentally set an incorrect value the camera may get stuck somewhere causing even the console to not display. It's there if you call it though, so use your blind typing skills to get back to a valid mode.
You can also cycle to the next value with the console command "vr_cycle_aim_move_mode"
Conclusion : Tout est configurable, si tu veux désactiver le capteur de mouvements sur le rift c'est possible

y' a qd meme plein de petits trucs niveau gameplay qui sont pas encore pris en compte, genre le Virtuix Omni, ça permet de se déplacer sur deux axes uniquement jcrois (stu veux jump, t'accroupir ou straf tu fais cmt?^^) et tu peux regarder qque part et aller ailleurs en meme temps?
