Abstract: A system includes first electronic devices and a digital signature carrier. Each of the first electronic devices has a network identifier distinct from another. The digital signature carrier is configured for recording a connective information list. The connective information list includes the network identifiers of all of the first electronic devices. A second electronic device includes a digital signature reader. The second electronic device is configured to read the digital signature carrier by the digital signature reader, extract the connective information list comprising the network identifiers and pair the second electronic device with each of the first electronic devices according to the network identifiers.

Abstract: An electronic apparatus wearable for a user and a display control method thereof are provided. The electronic apparatus includes an interactive display device, a supplementary input device and a processor device. The interactive display device displays a user interface. The processor device coupled to the interactive display device and the supplementary input device detects a clockwise movement and a counter-clockwise movement performed on the supplementary input device, wherein the clockwise movement and the counter-clockwise movement are associated with a function under an operation mode of the electronic apparatus. When one of the clockwise movement and the counter-clockwise movement is detected, the processor device correspondingly performs is the function. When the function is an interface rotation function, the processor device rotates the user interface on the interactive display device in accordance with the detected clockwise movement and the detected counter-clockwise movement.

Abstract: An interactive game system is provided. The interactive game system includes a head-mounted device (HMD), a game suit, a battery and a ground pad. The HMD executes a virtual reality program and displays video information of the virtual reality program to a user. The game suit is worn by the user and connected to the HMD. The game suit includes wireless sensors. The battery provides power to the HMD. The ground pad includes wireless charging devices arranged in a matrix to provide power. When the wireless charging device detects an approaching wireless sensor, the position information of the wireless charging device is transmitted to the approaching wireless sensor and a signal indicating whether the battery needs to be charged is transmitted to the wireless charging device. If the battery needs to be charged, the wireless charging device charges the battery via the approaching wireless sensor.

Abstract: A method and an apparatus for advising physical condition and a recording medium using the method are provided. In the method, multiple sensing devices are configured for a user to measure data related to the physical condition of the user. The data measured by the sensing devices is collected and integrated to estimate a current physical condition of the user. An advice is concluded at least based on the current physical condition of the user, and prompted for the user.
