  • Publication number: 20260332673
    Abstract: A method for controlling a sex toy of a model user is disclosed. The method includes controlling a first control node to establish a communication connection with a livestreaming platform, generating a control instruction for the sex toy of the model user in response to an interactive event initiated by a viewer user of the livestreaming platform toward the model user, and controlling the first control node to obtain a network resource identifier of a second control node. The first control node and the second control node are both located within a same data transmission network, and the same data transmission network is configured to allow the first control node and the second control node to transmit data via peer-to-peer communication. The second control node establishes a communication link, which is wired or wireless, with a control module embedded in the sex toy of the model user.

  • Publication number: 20260272768
    Abstract: A system and method for interactive tipping in a live streaming environment are disclosed. A viewer device displays, on a first interface, a representation of a tipping input, and displays, on a second interface, a live streaming session. During access to the live streaming session, a pointing operation is detected with respect to the representation of the tipping input, wherein the pointing operation comprises a gesture originating from a starting position within the first interface and directed toward outside the first interface. In response to the pointing operation, a tipping input associated with a host user of the live streaming session is activated. The system further generates visual effects rendered on the second interface based on the pointing operation, and maps kinematic parameters of the pointing operation to control instructions for an interactive device associated with the host user, thereby producing a physical response corresponding to the gesture.
