Sony has filed a bundle of patents regarding a hand-based controller for its PlayStation VR headset -- or any VR headset that ever gains critical mass -- that uses a flexible sensor to track finger location and position along with other motion and place-in-space detection systems.
The actual patent says it's for a Glove Interface Object that with a sensor that "quantifies an amount of force" being applied, which would mean one could apply pressure in the virtual world. Which might come in handy in some future apps.
Sony explains the entire concept of VR in the filing, making it sound as exciting as a natural extension of PowerPoint, with: "...a glove may be used by one or more remote users to interact in a collaborative way to examine documents, screens, applications, diagrams, business information, or the like. In such an implementation, users collaborating may use their gloves to touch objects, move objects, interface with surfaces, press on objects, squeeze objects, toss objects, make gesture actions or motions, or the like."
Imagine that! Imagine examining business documentation that doesn't really exist! Sony's imagineers even supplied this rough schematic, from which you could make one yourself...
