Abstract: A system for extended reality interaction includes a sender device and a recipient device. The sender device generates a data block based on action data corresponding to a virtual object and transmits the data block to a recipient device. The data block includes tag information for indicating the device generated the action data, object information corresponding to the virtual object, and motion information for describing motions of the virtual object in a first XR environment. The recipient device then presents the motions of the virtual object in a second XR environment according to the tag information, the object information, and the motion information.

Abstract: An electronic-card generating device stores profile data of a sender and character data of a virtual character corresponding to the sender. The electronic-card generating device decides an interaction mode of the virtual character according to the profile data of the sender and the character data of the virtual character, and generates an interactive electronic card according to the interaction mode of the virtual character. The interaction mode is a mixed-reality (MR) interaction mode or an augmented-reality (AR) interaction mode. The electronic-card generating device further transmits the interactive electronic card to a recipient device such that a recipient interacts with the virtual character through the interaction mode in an MR environment or an AR environment constructed by the recipient device.
