Mobile terminal and method of selecting lock function
First Claim
1. A method of initiating a lock function of a mobile terminal having a touch screen, the method comprising:
- detecting, when a plurality of touches occur on the touch screen, whether the plurality of touches occur on a predetermined area of the touch screen;
measuring at least one of a pressure, a current, or a capacitance at a plurality of points corresponding to the plurality of touches;
calculating at least one of each sum of the pressure, the current, or the capacitance measured at the plurality of points; and
initiating a lock function when the at least one of the each sum is greater than or equal to a preset value.

Abstract
A mobile terminal and a method of selecting a lock function thereof are provided. The method of selecting a lock function of a mobile terminal having a touch screen includes: measuring, when at least one touch occurs on the touch screen, at least one of a pressure, a current, and a capacitance of an area of the touch screen in which the touch occurs; and selecting, if at least one of the measured pressure, current, and capacitance is greater than or equal to a preset value, a lock function. Thus, by touching the touch screen in such a manner that a high current or capacitance may be measured in a specific area of the mobile terminal, a user can easily perform a desired function, thereby improving user convenience.

13. A method of initiating a preset function of a mobile terminal having a touch screen, the method comprising:
-
detecting, when a plurality of touches occur on the touch screen, whether the plurality of touches occur on a predetermined area of the touch screen; measuring at least one of a pressure, a current, or a capacitance at each of a plurality of points corresponding to the plurality of touches; calculating at least one of each sum of the measured pressures at each of the plurality of points, the measured currents at each of the plurality of points, or the measured capacitances at each of the plurality of points; and initiating the preset function when the at least one of the each sum is greater than or equal to a preset value. - View Dependent Claims (14, 15, 16, 17, 18, 19)
