Abstract: The present disclosure relates to methods, devices, and systems for invoking a capability of another device. In one example method, a source end device requests capability information of a sink end device. The sink end device sends the capability information to the source end device. The source end device sends first content and first request information to the sink end device when detecting a first operation of a user, where the first request information is used to request the sink end device to process the first content by using a first function. The sink end device processes the first content based on the first request information by using the first function, and sends a processing result of the first content to the source end device. The source end device prompts the user with the processing result.

Abstract: An input interface display method and a terminal are provided, and relate to the field of terminal technologies. When a terminal is switched to a one-handed input mode, a problem of poor user experience caused by a cumbersome setting operation of a user is solved. A specific solution includes: A terminal receives a first wake-up operation, determines target input keys in a currently displayed input interface in response to the first wake-up operation when determining that the terminal meets a wake-up condition, and then displays the target input keys at an associated position of a first side in the input interface. The input interface includes a plurality of input keys. The target input keys include keys whose distances from the first side are greater than a preset distance in the plurality of input keys. The first wake-up operation corresponds to the first side.
