Abstract: A virtual scene playback method is disclosed, which comprises: receiving a scene playback instruction and determining playback parameters according to the scene playback instruction, wherein the playback parameters include playback space and playback time; querying virtual space information and user model information corresponding to the playback parameters; and generating virtual scene playback content according to the virtual space information and the user model information. The present disclosure can save all the information in the virtual scene and play back the virtual scene corresponding to specific space and time. A virtual scene playback apparatus, an electronic device and a storage medium are also disclosed, which also have the above beneficial effects.

Abstract: Disclosed is a heat dissipation method for a head-mounted device. A temperature sensor, a heat dissipation fan and a power supply are disposed in the head-mounted device. The heat dissipation method for a head-mounted device comprises: obtaining a temperature acquired by the temperature sensor and an electric quantity of the power supply periodically or in real time; and activating the heat dissipation fan when it is determined that the head-mounted device satisfies a heat dissipation condition according to the temperature and the electric quantity. Further disclosed are a head-mounted device and a computer-readable storage medium. By means of the present disclosure, heat dissipation can be performed on a head-mounted device in a timely manner, thereby ensuring the service life of the head-mounted device.
