This application provides an eye tracking method, a device, and a storage medium. The method is applied to an electronic device that includes a first infrared light source and a camera module. The camera module includes a receiver and an emitter that is integrated with a second infrared light source. For the electronic device of this structure, a service scenario in which the electronic device is currently located is determined, and then in a case that the electronic device is in a high-precision eye tracking scenario, two infrared light sources are controlled to emit infrared lights to a target object that includes an eye of a user, and the receiver receives infrared reflection lights of a first infrared light and a second infrared light reflected by the target object, to generate a first infrared image of the eye, so that the electronic device can perform eye tracking based on the first infrared image. Because the camera module itself has one infrared light source, high-precision eye tracking can be implemented by only adding at least one additional infrared light source. Therefore, precision of eye tracking is ensured, and a quantity of screen holes of the electronic device can be reduced.

This application provides a shared cache management method and an electronic device, and relates to the field of electronic device control technologies. The method may match a processor and a running frequency of a shared cache, so that the processor can obtain data from the shared cache in a timely manner, thereby ensuring a running speed of an application. The method includes: setting, in response to a first event, the running frequency of the shared cache to a first frequency based on a focus application, user operation information, performance information of each processing core, and thread running information. The focus application is an application last operated by a user, the user operation information includes types and a quantity of operations performed by a user on the focus application in preset time, the performance information of each processing core is used to reflect a shared cache miss rate of the processing core, the thread running information is used to reflect running time proportions of a plurality of thread groups on each of N processing cores, and each thread group includes one or more threads running on the electronic device.

An embodiment of this application provides a video generation method, an electronic device, and a storage medium, which are applied to the field of terminal technologies. The method includes: receiving a first operation of a user triggering generation of a target video corresponding to a target theme; in response to the first operation, displaying an interface, of a voice assistant, that includes at least one candidate object corresponding to a keyword of the target theme; receiving a second operation of the user on a target object in the at least one candidate object; in response to the second operation, displaying a first material corresponding to the target object on the interface of the voice assistant, where the first material is an image or a video found by the voice assistant from a gallery; receiving a third operation of the user triggering generation of the target video; and in response to the third operation, displaying a thumbnail of the target video on the interface of the voice assistant, where the target video is generated based on the first material corresponding to the target object. In this way, a video of a theme expected by the user can be quickly generated. This simplifies a step of generating the video, so that user experience is better.

This application relates to the field of terminal technologies, and in particular, to a media resource editing method, an electronic device, and a storage medium. This method may be applied to the electronic device such as a mobile phone or a tablet computer. In this method, after a voice assistant is woken up, in response to a first dialog input, the electronic device displays a dialog box, and displays a first answer in the dialog box. Then, the electronic device displays a second answer in the dialog box in response to a second dialog input. Next, the electronic device displays a third answer in the dialog box in response to a third dialog input. In this method, when a quantity of media materials is large, for example, the quantity of media materials is greater than a first quantity threshold, the electronic device may replace a media material, for example, replace a media material in the second answer, in response to a dialog indicating to add a media material. In this way, the electronic device can flexibly adjust the media material.

An interface display method and a device are provided. The method includes: receiving an access request of a target interface; determining an animation element of a first type from elements of the target interface in response to the access request; and displaying the target interface, and displaying the animation element of the first type in the target interface in a manner of continuously displaying a same image frame. Through embodiments of this application, power consumption of an electronic device when displaying a user interface including the animation element of the first type can be reduced.

Embodiments of this application relate to the technical field of terminals, and provide an electronic device, a control method, and a related apparatus. The electronic device includes a wired interface, a coil unit, a first switch unit, a first charging unit, and a second charging unit. The wired interface is respectively electrically connected to the first charging unit and the second charging unit. The first switch unit is connected between the wired interface and the second charging unit. An end of the coil unit is connected between the first switch unit and the second charging unit. When the electronic device simultaneously performs wired reverse charging and wireless charging, the first switch unit is in an off state, no path exists between the wired interface and the coil unit, the electronic device performs the wired reverse charging through the first charging unit and the wired interface, and the electronic device performs the wireless charging through the coil unit and the second charging unit. In this way, an entire circuit is relatively simple and isolation between a link for wired reverse charging and a link for wireless charging can be implemented without a need of a plurality of switch units.
