Abstract

A mobile communication terminal including a first rotary key configured to generate a first signal when the first rotary key is rotated, in which the first signal indicates a direction and an amount the first rotary key is rotated, a second rotary key configured to generate a second signal when the second rotary key is rotated, in which the second signal indicates a direction and an amount the first rotary key is rotated, a display unit configured to display a screen thereon, and a controller configured to control a specific operation on the displayed screen based on the first and second signals.

Description

Technical field [0001] The present invention relates to a mobile terminal including at least one rotary key for controlling a displayed screen and a corresponding control method. Background technique [0002] In addition to basic call functions, mobile terminals also provide various supplementary service functions. For example, mobile terminals allow users to use short message service (SMS) to send and receive text messages, access the Internet, and play music or movies. However, due to the small size of mobile terminals, the amount of space available for displays and input devices is limited. [0003] Therefore, in order to efficiently use the limited space, the mobile terminal is provided with various function keys, navigation keys, etc. However, these keys are generally only used as up and down direction keys, menu selection keys, and the like. Summary of the invention [0004] Therefore, an object of the present invention is to solve the above-mentioned and other problems. ...
