Abstract
A keypad touch user interface method and a mobile terminal using the same are disclosed. If a touch is generated by a finger operation on a keypad installed with a touch sensor, the touch sensor detects the touch and a control unit identifies the type of the touch. According to the type of the touch, the control unit controls the display of a pointer on a display unit or displays an option window on the display unit. According to the result of identifying the type of the touch, if a new touch is generated by a finger in the state that another finger is touching a position on the keypad, the option window is displayed as with a right-click function of a mouse in a personal computing environment.
