Alan Yates, who likes to refer to himself as Chief Pharologist at Valve, is one of the senior engineers working on the Lighthouse tracking system and other VR technologies for the HTC Vive. According to him, both the Vive and the Rift use the same core features from Valve's research program. Yates went to Reddit yesterday and declared, "the CV1 is otherwise a direct copy of the architecture of the 1080p Steam Sight prototype Valve lent Oculus when we installed a copy of the 'Valve Room' at their headquarters." He went on to say, "I would call Oculus the first SteamVR licensee." With Valve's technology in their possession, it would have helped Oculus (Facebook) to acquire the engineers behind it, too. Michael Abrash was a key piece in that acquisition strategy, but they failed to grab much more. "Unfortunately for them they did not succeed and the great majority of the team that actually made it work remains at Valve," Yates said in September 2015.
