Abstract: A local multi-device fast space anchor point synchronization method for mixed reality includes any device located in the local space serves as a host to create a local network, and other devices join the local network as a guest; the guest and the host first exchange their respective local timestamps, and then calculate the time offset between the guest's local timestamp and the host's local timestamp to achieve time synchronization between the guest and the host; on the basis of time synchronization, the guest in the local network synchronizes the spatial coordinate system with the host through augmented reality picture tracking technology. Other guest can synchronize the spatial coordinate system with the host or synchronized guest to realize the spatial coordinate system synchronization between all devices in the local network. The synchronization method provided by the present application can use multi-person mixed reality applications without an external operator network.

The meeting summary component may include information describing the meeting and meeting assets. The meeting summary component may be posted into a messaging channel of the messaging platform.

Abstract: Provided are a method and apparatus for displaying active friend information, an electronic device, and a storage medium. The method for displaying the active friend information includes receiving an activity information checking instruction, where the activity information checking instruction is generated when a user triggers an entry control on a message page; and displaying an active friend list, where the active friend list displays activity information of an active friend of the user, and the active friend is a friend who is online in a recent preset time period. In this manner, a process of checking the active friend information is simplified and the time spent on checking the active friend information is shortened.

Abstract: A modular multi-hinge retractable rigid-flexible coupling space manipulator based on origami structure includes a plurality of folding units and a manipulator base. The modular design idea is adopted for the manipulator, which is formed by combining multiple folding units. the driving motors installed on each folding unit drive the folding units to stretch out, draw back and fold over, so that the manipulator can stretch out and draw back flexibly and bend in any direction to complete the work tasks in a variety of complex environments. For the manipulator, the flexible materials are added to the links of the folding units, and deformation can be effectively compensated, the mechanism is simplified, and impact is relieved. The torsional spring is additionally arranged in the folding units to play a supporting role, so that the manipulator can be placed in forward or in inverted direction to match with various bases.
