Abstract: A method to allow participation with multiple other players in a virtual reality (VR) board game includes steps of generating a board game scenario after a player with a mobile terminal logs in to a server and sending the VR scenario to the mobile terminal. The mobile terminal can transmit first and second signals, the first signal defining movement and track of a player piece being moved, and the second signal defining verbal expressions or commands by the player to trigger a preset event in the game. The first and second signals are analyzed and the player pieces in the VR scenario are moved accordingly. The method and system can also determine at least one player piece in the scenario that matches a condition for triggering a preset event or move in the VR game and make suggestions to the player accordingly.

Abstract: A multimedia file recommending device capable of matching entertainment file to user mood or state includes an input device to receive emotional value X sensed from or inputted by a user, a storage device, and a processor. The storage device stores multimedia files each associated with an emotional value. The processor selects a multimedia file from the multimedia database according to default rules, wherein a difference between the emotional value associated with the selected multimedia files and the emotional value X falling within a preset range. A multimedia file recommending method is also provided.

Abstract: A method for unlocking an electronic lock includes receiving a password transmitted from an electronic device, and determining whether the received password matches a preset password, the preset password is a certain movement of one or more electronic devices. If the received password matches the preset password, determining whether the electronic lock is operating in a temporary pass state or in a non-temporary pass state. The electronic lock is unlocked if the electronic lock is operating in the temporary pass state, but further user verifications are required if the electronic lock is operating in the non-temporary pass state.

Abstract: A method for generating a matching key of a lock includes obtaining user information input by a user of a smart key, determining whether the user is an authorized user of the smart key, obtaining lock information of the lock, obtaining key information of the lock, and generating a matching key to unlock the lock. When the lock is an electronic lock, the smart key generates an electronic matching key. When the lock is a mechanical lock, the smart key generates a mechanical matching key.

Abstract: A smart control device for controlling a television (TV) set includes at least one sensing device and a processor. The sensing device is configured to detect whether a person is in front of the TV set, and generate a first control signal upon determining that at least one person is in front of the TV set, or generate a second control signal upon determining that no people are in front of the TV set. The processor obtains the control signal generated by the sensing device, and turns on the TV set when the control signal is the first control signal and if the TV set was turned off, or turns off the TV set after a first predetermined time period elapsed, when the control signal is the second control signal and if the TV set was turned on.

Abstract: A method for displaying screen images from multiple electronic devices using a display apparatus, the display apparatus includes a display screen and a connection device. The method includes establishing connections between the connection device and two or more of the multiple electronic devices when the connection device receives connection requests from two or more of the multiple electronic devices, and controlling the connection device to receive screen image signals sent from the connected two or more electronic devices. The method further includes generating a number of display windows on a display area of the display screen, associating each of the connected two or more electronic devices with one of the plurality of generated display windows, and displaying screen images generated from the display image signals sent from each of the connected two or more electronic devices in the display windows associated with the connected two or more electronic devices.
