In one embodiment, a sliding track of a user is detected on a shortcut touchpad of user equipment to identify a sliding direction of the sliding track. The sliding direction is matched to an interaction interface of the user equipment. One or more objects, such as an icon or an input box, are determined on a touch display screen of the user equipment based on the sliding direction of the sliding track entered by the user. The shortcut touchpad may be made to be relatively small, facilitating a one-hand operation of the user and improving user experience.
