Method of unlocking mobile terminal, and the mobile terminal
First Claim
Patent Images
1. An unlock method which is performed in a mobile terminal with a touch screen, the method comprising:
- tracking a trajectory corresponding to a touch-and-drag operation of touching the touch screen and then dragging when the mobile terminal is in a lock mode;
determining whether one or more intersections occur on the trajectory;
determining, if one or more intersections occur on the trajectory, a number of the intersections; and
releasing the lock mode and executing a function including one or more applications corresponding to the number of the intersections.

Abstract
An unlock method for conveniently releasing a lock mode of a mobile terminal includes tracking a trajectory corresponding to a touch-and-drag operation of touching the touch screen and then dragging when the mobile terminal is in a lock mode, determining whether one or more intersections occur on the trajectory, and releasing the lock mode if one or more intersections occur on the trajectory. Accordingly, a touch input pattern for unlocking a lock mode is unlimited in terms of size, location, and pattern so that a user can freely touch the touch screen to release the lock mode.

6. An unlock method which is performed in a mobile terminal with a touch screen, the method comprising:
-
outputting an incoming call screen on the touch screen if an incoming call is received; tracking a trajectory corresponding to a touch-and-drag operation of touching the touch screen and then dragging; determining whether one or more intersections occur on the trajectory; determining, if one or more intersections occur on the trajectory, a number of the intersections; and determining whether to set up a call connection if the one or more intersections occur on the trajectory. - View Dependent Claims (7, 8)

9. A mobile terminal with a lock/unlock function, the mobile terminal comprising:
-
a touch screen configured to output a lock screen when the mobile terminal is in a lock mode; a touch screen controller configured to receive a signal corresponding to a trajectory of a touch-and-drag operation of touching the touch screen and then dragging, through the touch screen, and to output the received signal as a digital signal including coordinate values of the trajectory; and a controller configured to receive the digital signal from the touch screen controller, determine whether one or more intersections occur on the trajectory based on the coordinate values of the trajectory included in the digital signal, and release the lock mode if the one or more intersections occur on the trajectory, wherein the controller determines, if one or more intersections occur on the trajectory, a number of the intersections, releases the lock mode and executes a function including one or more applications corresponding to the number of the intersections. - View Dependent Claims (10, 11, 12, 13)
