Hand tracking and interaction adds a richness to AR experiences that bring them to life, and the Ur package makes it easy to implement. In this lesson you'll learn how to visualize the hand landmarks that Ur tracks, use them to interact with digital objects, and even occlude those objects behind the hand in order to layer our digital objects and physical world elements correctly.

Before getting started, complete the following steps:

1. Set up your development environment by following the steps in the Quickstart.
2. Follow the Create a simple shared AR experience tutorial or clone the project from the repository.
