I was surprised that I was immediately nauseous within seconds of putting on an Oculus, because I don't feel disorientation watching 3D movies or riding amusement park rides. It was something more deep seated than that, akin to motion sickness or ocean sickness, and I hadn’t felt such an immediate onset since I was young.
So I’m thinking that the component that’s missing is not so much better hardware, but a sense of control, because right now we are along for the ride but we want to be driving. The big off-putting things for me were:
* Screen door mesh appearance of seeing the mask area around pixels (which arguably shouldn’t be present on an OLED)
* Difficulty getting the focal point and field of view right (because really this is just a cell phone and some reading glasses, see Google Cardboard)
* Incorrect or missing association between gravitational up and simulation up (inner ear confusion)
* Not seeing my own body in the scene (needs integration with Xbox Kinect)
* Possible lag because the Rift may not be using movement prediction/dead reckoning (though I didn’t notice any, so maybe it is)
Really these are quite minor and easy to fix compared to what’s been accomplished so far. The only real expense is eventually going to be an affordable 4x HD display, because webcams for the optical tracking, gyros, tracking software and 3D drivers are all trivial or open source. Someday the controller will be a $5 chip like USB and work with any HDMI display.
Also the fact that the split screen projection works with ordinary video is causing all of this to go viral.
I’m trying to wrap my head around how stereoscopic panoramic video recording will work, because that’s the last thing stopping VR (not hardware).
I’m thinking the best way to solve that will be to scan a moving 3D panoramic scene into a computer and use the difference between frames to infer distance to each pixel. I’m having trouble finding a link, the closest thing I could find was the 2005 ShoWest where they talked about remastering a 2D movie like Star Wars episode IV into 3D at 48 fps:

Some other ideas might be to also use a laser rangefinder or ultrasound, light fields or split the image coming through the sphere with a partially reflective mirror onto two or more CCDs and have the computer infer the distance to each pixel by the correlation between the images. Anyone know any research/projects that explore recording panoramic 3D video?
