virtual reality controller
Most games seemingly insist on incorporating keyboard-movement in virtual reality, despite the presence (VR immersion) that the Oculus Rift delivers basically falls apart when keyboard-walking jerks the user out of their place. Analog sticks solve this problem, and since smartphones outnumber joysticks  nobody needs to get jerked around.
not for gaming
gamers are used to being jerked around (hah). (no, seriously) this controller is slow, and you will get fragged.
creates a virtual HID joystick with 3 analog axis (pitch, roll, yaw) mapped to the orientation sensors in the phone
- only works in joystick-enabled games
- run OSX app (it’s a status bar app), it auto-begins searching for a device
- connect through the iOS app (for connection status check OSX app)
hold the phone like a cafeteria tray, with the home button on the right
- 1: pitch
- 2: roll
- 3: yaw
###touch screen to re-calibrate joystick
it’s helpful to re-calibrate your physical orientation against gravity. a screen touch forces the identity matrix on the controller, release and the device is facing (the new) forward.
