Before Oculus, HTC & Sony had motion controls...
You had to make your own! Back in the DK1 days (DK1 is the first developer kit for the Oculus Rift) I spent many weeks obsessing with GlovePie scripts in order to make my own "motion controller". I finally got it working and fullfilled my dream of local multiplayer VR with motion controls. Keep in mind this video is FOUR years old now! In this video my wife and I play Left for Dead 2 on the Oculus Rift DK1 with Nintendo Wiimotes and Sony PS Navigators!
