What is Litho?

What is the Litho Controller?

Litho is a wearable controller for interacting with digital things in the real world. The controller is complemented by the Litho SDK which includes our unique tracking software and our interaction toolkit.

The controller itself is worn between your first and second finger. It has a capacitive trackpad on the underside, an array of motion sensors, and provides haptic feedback. Litho’s design means that you can wear it whilst doing everyday activities (e.g typing, driving, drilling).

To learn more about why we think Litho is important for the future of spatial computing read here.

What is the Litho Unity SDK?

The LITHO SDK provides an interaction framework, featuring off-the-shelf solutions to core interactions, including templates for tools such as object creation, scaling, rotation, selection and movement. These features make it easy for developers to build delightful and intuitive experiences, quickly. The SDK also provides a Litho Emulator which allows you to mimic the Litho input using your mouse and keyboard.

The SDK tracks the absolute position of the controller in space, using data from the phone’s camera and the controller's motion sensors.

Does the SDK come with the Litho controller?

Yes, each Litho device comes with a single license for the SDK. You can read more in our EULA which can be found here.  

I'm not a developer, can I still use Litho?

Right now, Litho is aimed at developers who are using Unity. If you don't have experience with Unity, our SDK contains many examples that make it easy to get started creating with relatively limited coding experience.

If you want to use Litho straight out of the box and you have an iPhone then you can download the LITHO app on the App Store. The app showcases a range of Litho interactions from creating and manipulating objects, to drawing shapes and creating 3D objects.
