Hand tracking with Varjo headset

Varjo’s VR-2 Pro is features built-in hand tracking technology from Ultraleap. It allows you to use your hands without any physical controller, and to reach out with your hands into VR world. Motions like pinching, grabbing, and interaction with objects accommodates a new level of immersion for your applications.

Setup

In order to enable the hand tracking module, download Ultraleap SDK for Varjo from our Downloads page. It is important that you download UltraleapSDK from Varjo website as we provide a software version that is specifically tailored for VR-2 Pro and stripped down of all unnecessary components.

When both the Varjo and Ultraleap SDK are installed, and the VR-2 Pro is correctly connected, you should see the Ultraleap icon turning green in Windows dashboard:
