User Interface Method Based on Keypad Touch and Mobile Device thereof

A user interface method and a mobile terminal using a keypad touch are provided to implement an operation environment of the mobile terminal approaching that of a personal computer, thereby replacing a convention scheme using a stylus or touch screen. A user interface method for use in a mobile terminal comprises the following steps. A touch on a keypad is sensed(S11). A touch direction is determined(S12). A screen of a display unit is divided into a plurality of blocks. When a focus is placed on one of blocks, the focus is moved in the determined touch direction(S13). At least two types of touch directions are classified at touch direction angles. A movement path of the focus is set by a type of the touch direction. The touch is sensed by a touch sensor mounted on a lower part of the keypad.
