Abstract: A BLUETOOTH reconnection method is used in a BLUETOOTH connection system that includes a first device and a second device. The method includes that the first device sends a BLUETOOTH Low Energy (BLE) advertising signal to the second device after a BLUETOOTH connection between the first device and the second device is disconnected. If the second device determines that the received BLE advertising signal is a first BLE advertising signal, the second device does not page the first device, and waits to receive a page packet sent by the first device. If the second device determines that the received BLE advertising signal is a second BLE advertising signal, the second device actively pages the first device, and the first device waits to receive a page packet sent by the second device.

Abstract: This application provides a gesture recognition method, and relates to the field of man-machine interaction technologies. The method includes: extracting M images from a first video segment in a video stream; performing gesture recognition on the M images by using a deep learning algorithm, to obtain a gesture recognition result corresponding to the first video segment; and performing result combination on gesture recognition results of N consecutive video segments including the first video segment, to obtain a combined gesture recognition result. In the foregoing recognition process, a gesture in the video stream does not need to be segmented or tracked, but phase actions are recognized by using a deep learning algorithm with a relatively fast calculation speed, and then the phase actions are combined, so as to improve a gesture recognition speed, and reduce a gesture recognition delay.

Abstract: Embodiments of this application provide a Bluetooth connection method, a system, and an electronic device. In the method, when a communication connection between an electronic device and a vehicle head unit is disconnected, the electronic device starts to scan a Bluetooth advertising signal. When a user carrying the electronic device is close to the vehicle head unit, the electronic device may obtain, through scanning, a Bluetooth advertising signal sent by the vehicle head unit. When obtaining, through scanning, the Bluetooth advertising signal sent by the vehicle head unit, the electronic device may start a vehicle manufacturer application when the vehicle manufacturer application is cleared by a system. The electronic device may reconnect to the vehicle head unit through Bluetooth by using the vehicle manufacturer application and a Bluetooth chip. Embodiments of this application can improve convenience of unlocking in a scenario in which a vehicle is insensibly unlocked.
