Abstract: This application discloses a gesture recognition method and apparatus accurately recognizes a gesture of a user and improves user experience. The method includes: obtaining echo data of a radar, where the echo data includes information generated when an object moves in a detection range of the radar; filtering out, from the echo data, information that does not meet a preset condition, to obtain gesture data, where the preset condition includes at least two of a distance, a speed, or an angle, the distance includes a distance between the object and the radar, the speed includes a speed of the object relative to the radar, and the angle includes an azimuth or a pitch angle of the object in the detection range of the radar; extracting a feature from the gesture data, to obtain gesture feature information; and obtaining a target gesture based on the gesture feature information.

Abstract: An example energy efficiency management method includes detecting a type of sensitivity to a performance requirement of a service running in a device, selecting a part of a plurality of running parameters of the device based on the type of sensitivity, where the selected running parameter is a running parameter with low relevance to the type of sensitivity of the service, and then adjusting the selected part of the plurality of running parameters or an associated parameter associated with the selected part of the plurality of running parameters so that a corresponding resource that is in the device and that is occupied by the service is reduced. Power consumption of the device after the adjustment is lower than power consumption of the device before the adjustment.
