Abstract: This application provides a method and an apparatus for controlling movements of a virtual object. The method includes displaying a target perspective picture of a target application, and superimposing a virtual joystick and a movable area of the virtual joystick on the target perspective picture; starting the virtual joystick when a trigger operation corresponding to the virtual joystick is received; adjusting a position of the virtual joystick in the movable area according to a position change of a touch point when the virtual joystick is in an activated state, the position of the virtual joystick and a position of the touch point changing synchronously in real time when the touch point moves within an effective touch range, the effective touch range being larger than the movable area; and controlling a virtual object to move according to the position of the virtual joystick.

Abstract: A display adaptation method for an application executed by a terminal includes: displaying a setting interface for setting at least one zone boundary of an interface safe operation zone, the interface safe operation zone being a zone used for displaying a human-computer interaction control responsive to one or more gesture operations in the application; receiving a boundary setting operation triggered on the setting interface; determining positional parameters of zone boundaries of the interface safe operation zone according to the boundary setting operation; and generating, according to the positional parameters, the interface safe operation zone adapted to the terminal.
