For those who came in late, the Power Glove was a late 80s peripheral for the Nintendo Entertainment System. According to the patent Sony’s version of the glove is straight-forward enough and it is unlikely to be as bulky like the Power Glove. It will be probably headed for its own VR system.
The gamer would be using a head-mounted display so the peripheral would not need too much functionally.The documents refer to hand flexor sensors that indicate a level of precision tracking at the fingertip level, as well as some sort of cloud network processing offload. Sony could technically let gamers use the gloves for non-VR purposes but that does seem unlikely.
The patents were filed in 2014, but were only just now revealed to the public. With PlayStation VR expected to launch the first half of 2016. It is possible that these are the gloves which will go with it.
