Assistance can be provided to AV users through projection of graphical figures. A system may receive a request for assistance from a user of an AV. The system assigns the request to an agent who can assist the user. The system further provides a graphical representation (e.g., an avatar) of the agent to a device that can project the graphical representation to the user. The user can have a conversation with the graphical representation, e.g., based on information provided by the agent. The system can also provide an audio filter to the device for modifying an audio content presented by the device so that the modified audio content appears as if it is made by the graphical representation. The device may be a part of the AV or a client device of the user that can present VR, AR, or MR content. The device may be mobile.
