about gemini


Ultraleap Gemini is our fifth-generation hand tracking platform with the most robust, flexible hand tracking ever.

Our hand tracking has always been world-leading, so what’s new?

Improved two-handed interaction

Ultraleap Gemini has a noticeable improvement in tracking both hands when they’re close together or overlapping. This means more reliable tracking performance even when hands are overlapping each other, or interacting.

Significantly more robust and accurate

Improved side to side finger fidelity, arm accuracy noticeably improved, improved hand rotation sensitivity (especially for fists).

Improved initialization

Improvements in hand detection mean that hands are tracked as soon as they enter the field of view. In HMD mode stability is also noticeably improved during initialization and termination.

Robust for different hand anatomy

Noticeably improved performance across a wide range of hand sizes.

New Tracking Mode

Ultraleap Gemini now supports a new camera orientation mode – Screentop. In addition to Desktop mode and HMD mode, we now support devices angled down towards the user. For TouchFree users this means a new camera position, Above Facing User, is enabled.

Streamlined Visualizers

Previously we had both a Diagnostic Visualizer and a VR Visualizer. We’ve deprecated our Diagnostic Visualizer in favour of a single Tracking Visualizer that can toggle between Desktop, HMD and Screentop modes.

SDK installer

You now have the option to install the SDK alongside the Tracking Service. The SDK will be installed in the same folder as the Tracking Service.

Online LeapC API documentation

You can now find the API Reference, The LeapC Guide, and examples on the Ultraleap Developer Resources Site.

Updated feel

You’ll notice a refreshed look and a streamlined installation process. We’ve changed the installation path so that all components are now installed within an Ultraleap folder. The Control Panel has had visual updates, and we’ve simplified how camera and software status is displayed.

Updated minimum requirements:


  • Windows® 10, 64-bit

  • Intel® Core™ i3 processor 5th Gen (must support AVX instructions)
