- Hand Tracking: This building block enables another main feature of mixed reality: the ability to interact with virtual objects using their hands. The Hand Tracking building block will show you a representation of your hands and enable you to grab, push, and poke virtual objects around you. It will also allow you to recognize hand gestures. For example, a pinch can be recognized and used in your gameplay. Use this building block whenever you want the user to interact with virtual objects using their hands.
- Camera Rig: This building block provides everything required to enable head tracking and stereo rendering, as well as most mixed reality capabilities in Unity. It will be installed as a required dependency for most other Building Blocks. Camera Rig provides everything required to use the Presence Platform capabilities in Unity. It is a mandatory building block. It will be installed by default whenever you install another building block. Without it, you won’t be able to get Presence Platform features to work properly.
- Virtual Hands: This building block allows the user to see a representation of their hands in the headset. This capability comes from our Interaction SDK, and allows a large number of interaction possibilities. Use this building block whenever you want the user to see a representation of their hands, or when you intend to use more advanced interaction capabilities from the Interaction SDK.
