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.

A ready-to-go project is available at HPTK-Sample.

# Main features - **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 # Documentation Some documentation entries: - [Home](https://jorge-jgnz94.gitbook.io/hptk/) - [Setup](https://jorge-jgnz94.gitbook.io/hptk/setup) - [FAQs](https://jorge-jgnz94.gitbook.io/hptk/faqs) # Supported versions - Unity 2022 - Unity 2019-2021 (Legacy) # Supported input ## Hand tracking - Meta Quest - Android - Leap Motion - Standalone ## Controllers - Oculus Touch - WMR - Vive - OpenVR # Supported render pipelines - Universal Render Pipeline (URP) - Standard RP # Getting started with HPTK (Oculus Quest) 1. Obtain **HPTK** 1. Change **ProjectSettings & BuildSettings** 1. Import the built-in **integration packge** (if needed) 1. Drag & drop the **default setup** to your scene 1. **Build and test** Check [documentation](https://jorge-jgnz94.gitbook.io/hptk/setup) for a detailed **step-by-step guide**. # Author **Jorge Juan González** [LinkedIn](https://www.linkedin.com/in/jorgejgnz/) - [Twitter](https://twitter.com/jorgejgnz) - [GitHub](https://github.com/jorgejgnz) ## Acknowledgements **Oxters Wyzgowski** - [GitHub](https://github.com/oxters168) - [Twitter](https://twitter.com/OxGamesCo) **Michael Stevenson** - [GitHub](https://github.com/mstevenson) Andreea Muresan, Jess Mcintosh, and Kasper Hornbæk. 2023.
