VR enhancement with Blue Tooth

To help movement feel more 'realistic' while sitting in a chair:

Link a phone via blue tooth as an extra input device, not to be tapped, but to give orientation input from any swivel chair users might choose to play in.  Benefits from this that may allow our brains to better accept the situation:

-Can't turn your head with a joystick. (feels very weird)

-Must turn your chair to re-orient to a new forward-and-back, just like turning our pelvis IRL for more convenient movement in a new direction. (this would allow for looking over your shoulder while running away from a creeper. etc... etc...)
