Breakdown of Unity Modules

Hands module

Our Hands Module is a set of scripts to help you bind Ultraleap data to your own hand assets. You can now import your own customized hand models and have them work with our world-leading hand tracking.

Don’t have your own hand models? We have a range of optimized and rigged hand models you can choose from.

Interaction Engine

A customizable layer that exists between the Unity game engine and real-world hand physics. Use the Interaction Engine to create natural object interactions and user interfaces. Supports both hands and PC controllers.



The Core package provides the foundation for VR applications with a minimal interface between Unity and our hand tracking controllers.



Current and past versions of our Unity Modules can be found in Legacy Releases.
