It's really sad to see no mention of Valve anywhere in the article. The work that was done at Valve in 2012-2013 on VR hardware and software was critical to the success of Oculus. Valve created a complete VR demo that was shown to Andreessen-Horowitz near the end of 2013, and was a deciding factor in their decision to invest, as well as Facebook's decision to buy. At that time, the best hardware created by Oculus did not have 6DOF, high-resolution tracking. It did not have low-persistance, globally-illuminated displays. It did not have proper lens distortion correction. It did not have presence. Basically, all of the hardware factors that have made modern VR exciting were discovered and developed by the team at Valve. Unfortunately, Valve was not able to capitalize or commercialize all of this work, and basically just gave it away through a very awkward interaction. Source: I worked there on VR. Of course, they are now working with HTC on the Vive, which is really great, and is going to give Oculus major competition. http://media.steampowered.com/apps/abrashblog/Abrash%20Dev%20Days%202014.pdf http://media.steampowered.com/apps/abrashblog/Abrash%20Dev%2...
