PaperDude VR, an impressive-looking technology mash-up from Globacore, combines the Oculus Rift, the Microsoft Kinect, and the Wahoo KICKR Power Trainer for one ridiculously immersive stationary bike ride.
This Unity-based game pays tribute to the classic arcade game Paperboy, and it uses the KICKR sensor to detect the speed of the bike, the Oculus Rift headset to allow the player to look around an entire 360 degrees, and the Kinect to track your motion as you "ride."
Although this is just a prototype, it is clear from the video that this is a functional game, not just a tiny tech demo. Globacore has even listed some potential upcoming additions, including obstacles to avoid and online leaderboards. And it provides one more reason to own the Oculus Rift: it can gamify exercising.
