A recent image has showed up online that displays the Battlefield 4 Xbox One Kinect options. Voice Commands, leaning, and headtracking are all shown.  In the video, I discuss how this could potentially work within the game.  Also notice that there appears to be a scroll bar on the voice commands.  So it is possible that there are many more voice commands.  So far, DICE hasn’t mentioned whether or not the same features will be available for the PS4 Camera.
