The project I want to present is not a game but a platform combing real-time motion capture with Oculus VR headset.
As you can see in the following video, this project enables multiple users to interact in a same physical space while visiting various virtual environments. They can pass or throw object to each other, touch physical elements, etc...
This project will be present in August at SIGGRAPH 2015 in Los Angeles. Attendees will be able to test the platform and experience this very impressive VR experience.
