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

Supported render pipelines

• Universal Render Pipeline (URP)

• Standard RP

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.
