The management system 210 enables real-time transformation of the browsing scene in response to the transformation of the signal, creating an immersive browsing effect. The detection threshold of each sensor can be adjusted by a user, so that unintended scene changes caused by over-small threshold and misoperation or insensitivity of induction caused by over-large threshold can be avoided. In the inductive display mode, the wearable device 100 establishes a connection with the map theme album. When the map is entered into the mode, the corresponding map theme album catalog is firstly displayed, and the theme characteristics of the album are prompted through voice. The user can select to skip the directory display and the voice prompt through the voice instruction, or select the corresponding directory for browsing through the voice instruction. The browsing mode is the same as the automatic browsing mode, and is not described in detail. The browsing instruction for the album is not limited to the replacement of the chapter. For example, the user sends a voice instruction to jump to the second chapter, after receiving the voice instruction, the wearable device 100 establishes a connection with the wireless communication unit of the map theme album through the wireless communication unit, and sends the voice instruction to the map theme album, and the map theme album sends the corresponding content in the map theme album storage system to the browsing system of the wearable device through the wireless communication unit based on the instruction, so as to form an immersive browsing effect. It should be noted that the control system 200 and the wearable device 100 may be integrated or separated, and when separated, they may be disposed at a remote location and communicate with the wireless communication unit 260 of the wearable device 200 through the wireless communication unit 160, and the map theme album may be stored in the wearable device 200, periodically updated through the control system 100, or stored in the control system 100, and transmitted through the network when browsing is needed.
