Overview

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.

This documentation is under construction.

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

  • Scale-independent. Valid for any hand size

  • State-of-the-art configurable hand physics

  • Define strategies to deal with tracking loss

  • Physics-based touch/grab detection

  • Tracking noise smoothing

Supported versions

  • Unity 2020.x

  • Unity 2019.x

Supported input

Hand tracking

  • Oculus Quest 1/2 - Android

  • Hololens 2 - UWP

Controllers

  • Oculus Touch

  • WMR

  • Vive

  • OpenVR

Getting started with HPTK

  1. Obtain HPTK.

  2. Import Oculus Integration.

  3. Configure Build Settings (Oculus Quest).

  4. Configure Project Settings (!).

  5. Setup a scene with hand tracking support (Oculus Quest).

  6. Setup HPTK specific components.

  7. Setup platform specific HPTK components (Oculus Quest).

  8. Modify/Create HPTK Configuration Assets (if needed).

Check Setup for a detailed step-by-step guide.
