The Litho looks like a set of miniature sci-fi brass knuckles, but it's actually a motion controller that's going on sale today for developers, with the goal of launching for everyone by the end of the year. Developed by a three-person team in the UK, the Litho
fits around the first two fingers of your hand. It combines motion-control capabilities and haptic feedback with a small underside trackpad, so you can use it with a combination of pointing, swiping, and tapping. Now, developers just have to figure out what it's good for.
Nat Martin, head of the Litho's design team, says the controller was conceived with augmented reality glasses like Microsoft's HoloLens in mind. It offers basic support for the HoloLens, but for now, it's largely built around Apple's mobile augmented reality platform ARKit. One demo video shows wearers placing objects in an augmented reality iOS app. Another shows people controlling smart home gadgets like thermostats without pulling out their phone.
