At the moment, the mainstream VR market is mostly a two-horse race, with Oculus Rift and the HTC Vive taking the lion’s share of the market. Not that others haven’t tried. Microsoft has its own Windows Mixed Reality platform and Sony came even earlier with the PlayStation VR, formerly codenamed “Morpheus”. PS VR, sadly, still has a lot of growing up to do from a technology standpoint. Fortunately, at least based on these two patents filed in Japan, the company has given its motion controllers some serious thought that will hopefully translate into action.
