Abstract: A client device selects animations for an AR character by prompting a large language model (LLM) to select from a set of possible animations for the AR character. The client device captures an image of its environment using a camera and identifies objects that are depicted in the image. The client device generates a prompt for an LLM that instructs the LLM to select from a set of candidate actions for an AR character to perform based on the identified objects. The LLM returns a response to the client device and the client device extracts a set of selected actions from the LLM's response. The client device identifies a set of animations that correspond to the actions selected by the LLM and renders AR content that depicts the AR character performing those actions. The client device augments the captured image to include the AR content and displays the augmented image.
