Abstract

A user interface method and a mobile terminal is disclosed. If a finger touches and moves in a specific direction on a keypad having a touch sensor, a touch is detected by the touch sensor and a type of touch direction is identified by a control unit according to the angle of a touch direction. A screen of a display unit is partitioned into a plurality of blocks, and a screen highlight is located at a specific block. The control unit for moving the screen highlight on the display unit according to the type of the touch direction. A path of the screen highlight is set in one of a forward direction with continuous movement, a forward direction with discontinuous movement, a backward direction with continuous movement, and a backward direction with discontinuous movement. A user interface according to the present invention can include a pointer in the display unit, the pointer being controlled by linking a pointer position with a touch position.

Description

technical field [0001] The present invention generally relates to a user interface in a mobile terminal, and more particularly to a user interface method using a finger keypad touch and a mobile terminal using the same. Background technique [0002] With the recent development of the technology of mobile terminals such as mobile phones and personal digital assistants, mobile terminals have been widely used in daily life. With the popularization of mobile terminals, user demands have been diversified, and competition among mobile terminal suppliers is fierce. Accordingly, people continue to develop mobile terminals that provide more functions and higher convenience. Especially by adding various multimedia functions as well as wireless Internet functions to the mobile terminal, the operating environment of the mobile terminal is now being improved to the level of personal computing. [0003] The size of the mobile terminal is relatively small because the mobile terminal must...
