Inside-Out Body Tracking (IOBT) The implementation of IOBT will allow the game to accurately track the position and orientation of the player's arms and torso. This will vastly improve not only immersion for the player by visually offering the correct position of the player's elbows, but it will also allow for more reliable chest placements (ammo, guns, grenades, etc.) via the use of torso tracking. Gone are the days of turning just your head and having your in-game torso magically turn alongside it. Your torso will stay where it actually is. With IOBT implemented, the player will also never have to worry about manually setting player height or arm length, as the game will already know your exact metrics. No more immersion-breaking stretchy arms. This feature (IOBT) is more important than people think. It's a game-changer for immersion.
