Unobtrusive, universal, and intuitive: Litho is a wearable controller for augmented reality which allows precise, intuitive input for AR applications. The device has a touch surface on the underside, an array of motion sensors and provides haptic feedback. Versatile tracking: Crucially, LITHO does not rely on external tracking systems to work, enabling use in a much wider range of scenarios (outdoors, in large areas, etc). Our tracking software uses a range of data streams to provide the best tracking possible in a given context. A spatial interaction toolset: The Litho device, in combination with the Software Development Kit (SDK) and suite of example projects, provides a complete package for developers looking to produce AR apps featuring precise and intuitive manipulations in 3D space.
