Abstract: Embodiments of this application provide an information processing method, a device, a system, a storage medium, and a computer program product, and relate to a web conferencing technology. In the method, when a plurality of users join a web conference by using a plurality of participating terminal devices, at least two users may use their own participating terminal devices. In addition, screen sharing is performed by using a web conferencing system. Therefore, the plurality of participating terminal devices in the conference may display, on screens of the plurality of participating terminal devices, information shared by the at least two sharing terminal devices. In this manner, the web conferencing system supports screen sharing performed by a plurality of sharing terminal devices at a same moment, and each sharing terminal device can control the screen sharing. This facilitates information sharing between the pluralities of users, and improves communication efficiency between the users.

Abstract: An operation method for an electronic device and an electronic device are provided, and relate to the field of electronic devices. In a split-screen display scenario, a function of quickly opening a specific interface by using an entered gesture is implemented. When a screen of the electronic device is split for display, the electronic device receives different operations for a side that is of a single window and that is closely adjacent to another window, and the electronic device may execute a corresponding event only for the window, for example, display a previous-level interface of a current interface in the window, display a desktop in the window, or display a task list interface in the window, and an interface displayed in the another window remains unchanged.

Abstract: Embodiments provide a terminal device control method and a terminal device. The method includes: when a bending behavior of a flexible display occurs, determining a bending parameter of the flexible display, where the bending parameter includes at least one of a bending time parameter, a bending location parameter, a bending direction parameter, and a bending degree parameter; and adjusting a user interface (UI) of the flexible display based on the bending parameter, or generating, based on the bending parameter, a command corresponding to a first application. According to the method provided in the embodiments, the bending behavior of the flexible display is abstracted as the bending parameter, and the bending parameter is used as input of the application. This manner can effectively improve user experience.

Abstract: Example anti-accidental touch methods and apparatus are described. One example of the methods includes obtaining a screen touch event detected on a touchscreen and a key touch event detected on a target key by a terminal. The terminal determines one of the screen touch event and the key touch event as an accidental touch operation based on a touch position and a touch time of a touch point in the screen touch event and a touch position and a touch time of a touch point in the key touch event. The terminal executes an operation instruction corresponding to the key touch event when the accidental touch operation is the screen touch event, or executes an operation instruction corresponding to the screen touch event when the accidental touch operation is the key touch event.
