Hand Physics Toolkit (HPTK) is a toolkit to implement hand-driven interactions in a modular and scalable way. Platform-independent. Input-independent. Scale-independent. Can be combined with MRTK-Quest for UI interactions.

You can clone a ready-to-go project at HPTK-Sample.

• Data model to access parts, components or calculated values with very little code
• Code architecture based on MVC-like modules. Support to custom modules
• Platform-independent. Tested on VR/AR/non-XR applications
• Input-independent. Use hand tracking or controllers
• Pupettering for any avatar or body structure
• Scale-independent. Valid for any hand size
• Realistic configurable hand physics
• Define strategies to deal with tracking loss
• Physics-based hover/touch/grab detection
• Tracking noise smoothing

• Unity 2020.x
• Unity 2019.x

• Oculus Quest 1/2 - Android
• Leap Motion - Standalone
• Hololens 2 - UWP

• Oculus Touch
• WMR
• Vive
• OpenVR

• Universal Render Pipeline (URP)
• Standard RP

1. Obtain HPTK
2. Change ProjectSettings & BuildSettings
3. Import the built-in integration packge (if needed)
4. Drag & drop the default setup to your scene
5. Build and test
