3 is a flowchart illustrating a method of setting a touch lock area according to an embodiment of the present invention.

Referring to FIG. 3, the controller 180 receives a user command of touching the front case 100-1 and dragging the display case 151 (S310). The display unit 151 is surrounded by the front case 100-1. When the user touches the front case 100-1 using a touch pointer (for example, a finger) and then drags the touch pointer to the display unit 151, the controller 180 controls the front case 100-1. ) And receive a user command for dragging to the display unit 151.

When the front case 100-1 is touched and a user command for dragging the display unit 151 is received, the controller 180 sets and displays the touch lock area (S320). In general, when a user command of touching through a touch screen is received, the portable terminal executes a specific application corresponding to the current mode and the location of the touched area. However, even if a user command for touching the touch lock area is received, the portable terminal does not perform a specific application corresponding to the current mode and the location of the touched area. That is, when a touch lock area is set on the touch screen, the portable terminal executes an application by touching a region other than the touch lock area.

When the controller 180 sets the touch lock region, the controller 180 sets a region of a predetermined range including the dragged distance as the touch lock region with reference to the dragging operation. For example, an area having a radius of a point where the drag is terminated around the point of the touched front case 100-1 may be set as the touch lock area. Alternatively, when the trajectory dragged together with the front case 100-1 forms a closed curve, the area within the closed curve may be set as the touch lock area.

Meanwhile, the controller 180 determines whether a user command for touching the touch lock area of the touch screen is received (S330). Even if a user command to touch the touch lock area is received (S330 -Y), the controller 180 does not operate according to the touch and maintains the previous screen as it is (S340). For example, it is assumed that shortcut icons for executing a weather application are displayed in an area other than the touch lock area. Although received, the controller 180 displays the same screen as before the touch without executing the weather application.

Alternatively, the controller 180 determines whether a user command for touching an area other than the touch lock area of the display unit 151 is received (S350). When a user command to touch an area other than the touch lock area is received (S350-Y), the controller 180 operates according to a touch with reference to a preset manual and displays an operation screen on the touch screen (S360). For example, when a shortcut icon for executing a weather application is displayed in an area other than the touch lock area, and a user command for touching an area in which the shortcut icon is displayed is input, the mobile terminal executes a weather application to execute a weather application. Display the run screen on the touch screen.

When the display unit 151 is a touch screen as described above, if a touch lock area is set in the touch screen, the portable terminal does not execute an operation according to the touch even if a touch is received in the touch lock area. Therefore, it is possible to prevent the operation of the portable terminal irrelevant to the intention of the user.

Referring to FIG. 4, a screen including a touch lock area is displayed on the display unit 151 (S410). The controller 180 determines whether a user command for touching and dragging a boundary area of the touch lock area is received (S420). The user may touch the boundary area of the touch lock area by using a finger and then drag the finger a specific distance in a specific direction while touching. Then, the controller 180 determines that a user command for touching and dragging the boundary area of the touch lock area is received.

When a user command of touching and dragging the boundary area of the touch lock area is received (S420 -Y), the controller 180 displays the size of the touch lock area by changing the size according to the dragged distance and direction (S430). More specifically, when a user command for touching the boundary area and dragging the touch area is received, the controller 180 reduces the size of the touch lock area in proportion to the dragged distance. In addition, when a user command of touching the boundary area and dragging the area other than the touch lock area is received, the controller 180 enlarges and displays the size of the touch lock area in proportion to the dragged distance.

In addition, the controller 180 determines whether a user command for touching and dragging an inner region of the touch lock region is received (S440). The user may touch the inner region of the touch lock area using a finger, and then drag the finger a specific distance in a specific direction while touching. Then, the controller 180 determines that a user command for touching and dragging an inner region of the touch lock region is received.

When a user command of touching and dragging an inner area of the touch lock area is received (S440 -Y), the controller 180 moves and displays the touch lock area in response to the dragged distance (S450). When the touch lock region moves, the controller 180 may set and display a new touch lock region in addition to the existing touch lock region to set the touch lock region having a specific shape. For example, when the existing touch lock area is part of a circle, a new touch lock area may be additionally set if the remaining circle can be displayed by the movement of the existing touch lock area. In addition, when all of the previously displayed touch lock regions cannot be displayed due to the movement of the touch lock region, only a part of the touch lock region may be displayed.

As described above, since the size and position of the touch lock area are variable, the user can set a touch lock area suitable for the user.
