Abstract

A method, an apparatus and a computer-readable medium for adjusting size of screen object adapted to a mobile device having a touch screen are provided. In the method, a display direction is randomly selected for each of at least one screen object to display each screen object on the touch screen, where each screen object has at least one object size capable of being adjusted. Then, the touch screen is used to detect a first touch and a second touch performed on one of the at least one screen object. The object size of the screen object being touched is adjusted according to the display direction thereof and a relative moving direction of the first touch and the second touch.
