Systems and methods for representing user interactions in multi-user augmented reality
Systems and methods are provided for the generation of augmented reality (AR) content that provides a shared AR experience involving multiple users. Shared AR experiences can improve the communication and collaboration between multiple simultaneous users. According to an embodiment, AR content is generated for a first user in a shared AR experience. The AR content includes at least one of a render of a model, a virtual representation of a second user in the shared AR experience, a virtual representation of a user interaction in the shared AR experience, and spatial audio content. Modifications to a shared AR experience are also provided. These modifications may be initiated based on instructions from one user and be reflected in the AR content generated for multiple users.
