Is Sony working on a glove controller? NeoGAF user Rösti seems to think so and has highlighted three detailed patent applications numbered 14/517733, 14/517741, and 14/503275.
Between the three patents the patents account for everything you would expect from a VR controller which would almost definitely be paired up with the companies PlayStation VR head mounted display.
While I want to holler "Powerglove!" out of my nearest window, it seems to be solely for the purpose of hand tracking, with a bunch of illuminated points for camera tracking, similar to the Playstation Move.
Here's the coolest thing: the gloves main purpose is to create "a virtual hand in a view of a virtual environment" with it acting in accordance with your finger positioning. This is useful if you need to say, swing a sword or point a gun.
From the look of things, the glove will have flex and pressure sensors on each individual finger as well as sensors to detect when your fingers are touching your palms or each other.
Obviously the best case scenario is for haptic feedback - allowing you to juggle objects with actual heft or actually grip a virtual doorknob and feel it in your hands. There's no real detail here on these parts, although the patents do indicate that the glove would be attached to a bracelet which might house some additional gizmos.
Obviously filing a patent doesn't say anything about Sony's intent to produce a thing, more that they've designed an object; but we can dream, eh?
