1. A user interface method using a touch, the method comprising:
- calculating a time difference between a previous tap and a current tap and a distance between the previous tap and the current tap; and
determining an operation mode based on the time difference between the previous tap and the current tap and the distance between the previous tap and the current tap, andwherein the determining of the operation mode based on the time difference between the previous tap and the current tap and the distance between the previous tap and the current tap comprises;
changing the operation mode to a successive tap operation mode when the time difference between the previous tap and the current tap is smaller than a predetermined time threshold and the distance between the previous tap and the current tap is greater than a predetermined distance threshold.

Abstract
Disclosed is a method and apparatus for performing an operation, such as enlargement, reduction and rotation of a screen of a terminal having a touch screen, with one hand using successive touches on the screen. A method of controlling the touch screen may include determining whether two points spaced at a predetermined distance threshold or longer on the touch screen are input as a previous tap and a current tap within a predetermined time threshold, analyzing the previous tap and the current tap to switch to a successive tap operation mode, and performing an operation according to a predetermined successive tap command in the successive tap operation mode.

12. A user interface method using a touch, the method comprising:
-
receiving a previous tap and a current tap; switching to a successive tap operation mode based on the previous tap and the current tap; and conducting an operation according to a predetermined successive tap command in the successive tap operation mode, and wherein the switching to the successive tap operation mode comprises; verifying whether a time difference between the previous tap and the current tap is within a predetermined time, verifying whether a distance between the previous tap and the current tap is a predetermined distance or longer, and switching to the successive tap operation mode when the time difference is within the predetermined time and the distance is the predetermined distance or longer. - View Dependent Claims (13, 14)

15. A user interface apparatus using a touch, the apparatus comprising:
-
an input unit configured to receive inputs of a previous tap and a current tap; and a processor executing a program stored in a non-transient medium configured to; verify whether a previous input is a tap input; calculate a time difference between the previous tap and the current tap and a distance between the previous tap and the current tap; determine whether the time difference between the previous tap and the current tap is within a predetermined time; determine whether the distance between the previous tap and the current tap is a predetermined distance or longer when the time difference between the previous tap and the current tap is within the predetermined time; change an operation mode to a successive tap operation mode when the time difference between the previous tap and the current tap is within the predetermined time and the distance between the previous tap and the current tap is the predetermined distance or longer; and perform an operation in the operation mode determined based on the time difference between the previous tap and the current tap and the distance between the previous tap and the current tap. - View Dependent Claims (16)
