OK, Marc Andreessen Thinks Oculus Has Figured It Out But To Me The Jury Is Still Out

 to the tune of $75 Million to get the Consumer Version to Market. Meanwhile Apple's Patent on Goggles for Media and Gaming comes to light, Sony's PS4 Visor Patent shows up yesterday. There is credible evidence Microsoft is working on the same. It is starting to look like the HMD version of the Oklahoma Land Rush.
None of Oculus' reported improvements, increased resolution, lower latency, tweaking the software do anything to overcome the root cause of VR Sickness:
" Sensory conflict theory states that since the visual input implies motion to the VR user while the vestibular system is getting a null signal , the resulting conflicting information to the brain induces simulator sickness."

The vestibular system disconnect means the inner ear is tricked into thinking it's moving when it is stationary. There's the conflict and no amount of increased resolution can change it. It looked like the Apple HMD had a series of vents around the padding of their device, no doubt for air circulation but perhaps just large enough for the brain not to be entirely convinced that the Virtual world it's viewing is the "real" world thereby negating or lessening the conflict.  Sony's visor compensates for this as well.I've never heard of Simulator Sickness in the  Training Systems that use the eMagin Z800 or similar for just that reason. The first great Virtual Reality Soap Opera is upon us. Popcorn.
