This is a demo showcase which has been shown in Beijing, Tokio, Seoul on IT exhibitions. Made for VRT World studios.
I don’t have a real Vive device so I recorded this video through the simulator.
Scene 2 (open space)
It has a feature of full-body tracking. Player movements are tracked using HMD, 2 joysticks and 3 generic trackers. So the player see himself inside of avatar repeating his movements. It adds a feeling of realism.
