Therefore, the present invention is not limited to the embodiments described below, but may be embodied in other forms. In the drawings, the width, length, thickness, etc. of the components may be exaggerated for convenience. Like numbers refer to like elements throughout.

As described above, the present invention may be a touch screen touch position by an user and an object on the touch screen (here, the object may be the entire display screen shown on the touch screen or a partial region or an image object of the touch screen display. The center point is connected, and a plurality of areas are distinguished and defined based on a straight line extending to the touch screen boundary, and the touch screen is controlled according to dragging in the area. In addition, dragging refers to a user gesture in which a position thereof is changed while the user input means (finger, stylus pen, mouse, etc.) is touched.

Hereinafter, an area generating step according to the present invention will be described in detail with reference to the accompanying drawings.

1A to 1C are diagrams illustrating an area division step according to an embodiment of the present invention.

Referring to FIG. 1A, a user touches a point 120 of the touch screen 110.

Referring to FIG. 1B, a plurality of areas connecting between the one point 120 and the center point 130 of the touch screen 110 and bordering a straight line 140 extending to the boundary 110 of the touch screen, Here, two regions 150a and 150b are defined. In particular, the two regions defined and separated by a straight line connecting the touch position 110 and the center point 130 have substantially the same area, and dragging directly from the touch position 120 to the plurality of regions. Focusing on the possibility, the touch screen is controlled according to the dragging in the divided area.

The present invention further distinguishes the touch of the present invention, which creates and defines an area for performing different commands by dragging, unlike a touch for performing a general command (for example, panning and clicking). Since it should be, it provides a manner in which the region is defined by a touch that satisfies a predetermined condition that is different from the normal touch. For example, when the same position is touched for a predetermined time or more, when the touch screen is touched for a predetermined intensity or more, dragging at or above a predetermined speed may be used as the predetermined condition.

Referring to FIG. 1C, after the regions 150a and 150b are defined, the user starts dragging 160 to any one of the regions, and a command corresponding to the region is performed by the dragging. . Various commands are possible with the above commands, and for example, a zoom command (zoom-in, zoom-out), volume control, data search, etc. may be possible, but in one embodiment of the present invention, the zoom command is used as the command. It was.

The user performs dragging 260 to one area 250a of the two areas. As shown in FIG. 2, the dragging is continuously performed from the touch position 220. Such a technical configuration has an advantage of performing a zoom command or the like with only the first touch without a separate touch operation.

A zoom-in command (+) is performed according to the dragging in the area 250a, where the center point of the zoom-in command is the touch position 220. As a result, the user can immediately perform the actual zoom command at the desired point and the zoom command is performed at the center of the screen. Therefore, the problem of the related art that the object needs to be centered through the panning gesture again after the zoom command is It can simply be overcome.

Referring to FIG. 2B, as the continuous dragging distance 260 increases, the degree of zoom-in of the screen (that is, the amount of the zoom-in command or the zoom-in ratio) gradually increases. In particular, since the zoom-in command is performed by dragging in an arbitrary direction within the area 250a, the physical limitation of dragging according to the touch screen size is not the present invention, and thus, the execution of the zoom command at an infinite ratio is prevented. It is possible.

2C and 2D, when the user wants to zoom out of the enlarged screen after performing the zoom-in command, the user may select one point 270 of the other area 250b instead of the one area 250a. After touching, another dragging is performed from the point 270. In this case, the another dragging is performed within a predetermined time after the dragging in the one area 250a, thereby maintaining the command execution mode by the defined area and the dragging in the area.

2C and 2D, the zoom-out command is performed according to the dragging distance in the other area 250b. As described above, the dragging distance determines the amount of instruction execution performed by dragging.

Based on the technical configuration of the present invention described above, a touch screen control method and control device according to the present invention will be described below.
