“Antilatency” is a positional tracking system for mobile VR (Gear VR, Google Cardboard, Google Daydream) that has multiplayer capability and an area of 30 feet by 30 feet (with four IR strips), or an area of any size or shape with additional IR strips. I got to try it at VRLA and it really works! Here is a preview: http://360rumors.com/2017/04/vrla-antilatency-roomscale-multiplayer-positional-tracking-system-mobile-vr.html
