Abstract: Example interface control methods and apparatuses, example electronic devices, and example readable storage medium are provided. One example method is applied to an in-vehicle infotainment system in a vehicle, and the in-vehicle infotainment system is connected to a mechanical component. The example method includes detecting, by the in-vehicle infotainment system, an operation performed by a user on the mechanical component. The in-vehicle infotainment system switches a focus window on an interface of the in-vehicle infotainment system from a first window to a second window in response to the operation, where the interface of the head unit is projected by a terminal device on the in-vehicle infotainment system.
