Developing a sense of "presence" is of crucial importance for both virtual and mixed reality experiences. As a rule of thumb, presence requires a minimum of 90fps, a 100+ degree field of view , 1k per eye and near-perfect hand tracking. However, to achieve these specs with a wireless HMD would require substantially more powerful GPUs, larger battery packs, and better heat rejection. We posit that with the advent of "world-scale" inside-out tracking (MS Hololens, Google Tango), tetherless high bandwidth solutions (eg. TPCast), and 1:1 pass-through video, it is now likely that a compelling mixed reality will emerge from Virtual Reality hardware manufacturers. In otherwords: AR/MR hardware developers will have a moving target on their hands as the HTC Vive, the Oculus Rift and the Sony PSVR become tetherless and are adapted to provide mixed reality capabilities.
