Abstract: The present application relates to the field of multimedia technologies, and proposes a method for outputting media content in live interaction, an electronic device, and a computer program product. The method includes: in a process in which a streamer performs live streaming by using a target product, obtaining live streaming feature information used to determine media content to be output; determining target media content based on the live streaming feature information; and outputting the target media content. In this method, when watching live streams, a viewer not only obtains regular live streaming information of the streamer, but also can receive additional target media content. With the target media content, the viewer can more intuitively perceive experience of using the target product by the streamer, thereby significantly improving the sense of novelty and immersion of the viewer while watching live streams, to improve viewership of live streams and boost product sales.

Abstract: A live streaming-based interactive method includes the following steps: receiving interaction data of users; where the users are viewers watching a target live streaming room on a live streaming platform; determining an audience emotional atmosphere in the target live streaming room based on the interaction data; determining live streaming visual effects based on the audience emotional atmosphere; and compositing the live streaming visual effects with a live streaming video to generate a composite live streaming video, and transmitting the composite live streaming video to the live streaming platform.

Abstract: Disclosed is an inertial percussion massager, including a percussion body provided with a free end and a drive end, a drive assembly, a drive strategy assembly, and a percussive massage portion arranged at the free end and configured to act on a target massage area in an impact manner to produce a percussive massage effect. The drive end is connected to the drive assembly. The drive strategy assembly is configured to control a motion strategy of the drive assembly and drive the free end of the percussion body to move at a frequency f. The frequency f is not less than 10 Hz. An inertia-based impact mechanism enables generation of a peak impact force stronger than that from traditional non-inertial percussion or pure vibration massage and facilitates more effective energy transfer even under same driving power, by optimizing mass distribution of the percussion body and/or increasing motion velocity.
