AR Interactions and Experiences

In some implementations, the disclosed systems and methods can detect an interaction with respect to a set of virtual objects, which can start with a particular gesture, and take an action with respect to one or more virtual objects based on a further interaction (e.g., holding the gesture for a particular amount of time, moving the gesture in a particular direction, releasing the gesture, etc.).In some implementations, the disclosed systems and methods can automatically review a 3D video to determine a depicted user or avatar movement pattern (e.g., dance moves, repair procedure, playing an instrument, etc.).In some implementations, the disclosed systems and methods can allow the gesture to included a flat hand with the user's thumb next to the palm, with the gesture toward the user's face.
