    Abstract: An input method and a smart terminal device. After a processor in the smart terminal device determines, based on a first detection solution of a first infrared sensor, that a target object enters or leaves a first space range from a first plane, the processor starts or stops displaying a cursor based on distances measured by ultrasonic sensors; and after the processor determines, based on a second detection result of a second infrared sensor, that the target object enters or leaves a second space range from a second plane, the processor starts or stops performing a confirmation operation based on a location of the cursor.

    Abstract: Embodiments of the present invention provide an automobile including a processor and a sensing apparatus, and the sensing apparatus is installed on a part that is of the automobile and that may be in contact with a hand of a driver, and includes a transmitter and a receiver. The transmitter sends a sound wave signal to the hand of the driver, and the receiver receives a reflected sound wave signal reflected by the hand of the driver, converts the reflected sound wave signal to an electrical signal, and sends the electrical signal to the processor. The processor analyzes the electrical signal to obtain a feature of the reflected sound wave signal, and recognizes an identity of the driver based on the feature of the reflected sound wave signal.

    Abstract: A smartwatch and, a method for controlling the smartwatch, where a plurality of capacitive touch sensors is disposed around a screen of the smartwatch. The method includes obtaining a calibrated capacitance value of each capacitive touch sensor, determining a quantity of touch points based on maximum values of calibrated capacitance values of the N capacitive touch sensors, where each touch point corresponds to one capacitive touch sensor, determining a location of each touch point based on a calibrated capacitance value of a capacitive touch sensor corresponding to the touch point and a calibrated capacitance value of a capacitive touch sensor neighboring to the capacitive touch sensor, and executing a control instruction matching the quantity of touch points and the location of each touch point.

    Abstract: An electronic device includes a display screen, a display control circuit, an active optical component, and an optical control circuit. The active optical component is located below the display screen. The display control circuit is configured to control refreshing of the display screen, and output a synchronization signal to the optical control circuit. The optical control circuit is configured to receive the synchronization signal, and control the active optical component to start light emission after a predetermined first delay that is after a moment corresponding to the synchronization signal to enable the display control circuit to refresh to one row of at least one row on the display screen corresponding to the active optical component after a predetermined second delay that is after the active optical component completes light emission.
