This repository, titled "XR playground," is an experimental project aimed at developing a hand-based gamepad using Unity and Mediapipe. It includes submodules and directories related to Blender and Mediapipe for 3D modelling and hand-tracking functionalities. The project leverages C#, Objective-C, and Makefile, focusing on creating an immersive XR (Extended Reality) experience. As part of this project, the mp-hand-gesture-detector subproject focuses on detecting hand gestures using Mediapipe. It provides scripts and models for recognizing various hand gestures, which can be integrated into applications needing hand gesture recognition. The video demonstrates the functionality and implementation of the hand-gamepad project, showcasing how hand gestures can be tracked and utilized as inputs for controlling virtual elements in an XR environment.
