Referring to FIG. 1, the touch screen device 110 includes a detector 111, a determiner 112, an event generator 113, a trajectory tracker 114, and an adjuster 115.

The touch screen device 110 may be implemented based on various types of microprocessor-based devices employing a touch screen such as a desktop PC, a mobile terminal, a PDA, a notebook computer, and a tablet PC.

The detector 111 detects a touch input on the touch screen.

The determination unit 112 determines whether the first touch input and the second touch input are sequentially sensed on the touch screen through the detection unit 111.

In this case, according to an embodiment of the present invention, when the first touch input is detected on the touch screen through the detector 111, the determination unit 112 detects the first touch input after detecting the first touch input. ) May determine whether the second touch input is sequentially sensed on the touch screen.

If it is determined that the first touch input and the second touch input are sequentially sensed on the touch screen, the event generator 113 generates an event related to the size adjustment of the screen displayed through the touch screen.

In this case, according to an embodiment of the present invention, the determination unit 112 sequentially after a predetermined time in a state in which the first touch input is maintained after the first touch input is detected on the touch screen. It may be determined whether the second touch input is detected.

In this case, when the event generating unit 113 determines that the second touch input is sequentially detected after the predetermined time after the first touch input is detected on the touch screen, the event associated with the size adjustment of the screen Can be generated.

The trajectory tracking unit 114 tracks the trajectory of the first touch input when an event related to the size adjustment of the screen occurs.

The adjusting unit 115 adjusts the size of the screen based on the trace of the tracked first touch input.

Hereinafter, the operation of the touch screen device 110 according to an exemplary embodiment of the present invention will be described in more detail with reference to FIG. 2.

2 is a view for explaining the operation according to the user's touch input method in the touch screen device 110 according to an embodiment of the present invention.

First, as shown by reference numeral 210, when the first touch input 201 is generated on the touch screen and the first touch input 201 is sensed through the sensing unit 111, the touch screen device 110. May perform an operation according to the first touch input.

For example, as illustrated by reference numeral 220, the touch screen device 110 moves the screen according to the movement trajectory of the first touch input 201 when the first touch input 201 moves from left to right. Or provide scrolling capabilities.

In this case, the determination unit 112 determines whether the second touch input 202 is sequentially sensed on the touch screen through the sensing unit 111 after the first touch input 201 is detected.

If it is determined that the second touch input 202 is sequentially detected after the first touch input 201 is detected on the touch screen, as shown at 230, the event generator 113 An event related to size adjustment of a screen displayed through the touch screen may be generated.

In other words, the first touch input 201 is detected on the touch screen, and as shown at 220, the touch screen device 110 performs an operation according to the first touch input 201. As illustrated in 230, when the second touch input 202 is detected on the touch screen, the event generator 113 may generate an event related to the size adjustment of the screen displayed through the touch screen. .

At this time, according to an embodiment of the present invention, the determination unit 112 is the first touch input 201 is detected on the touch screen after the first touch input 201 is maintained after a predetermined time after the state is maintained 2 may determine whether or not the touch input 202 is sequentially detected, and if the first touch input 201 is detected on the touch screen, the event generator 113 may detect the second touch after the predetermined time. When the input 202 is sequentially detected, an event related to the resizing of the screen may be generated.

In other words, when the second touch input 202 is sequentially detected after the first touch input 201 is detected on the touch screen, the event generator 113 may generate an event related to the resizing of the screen. However, only when the first touch input 201 is detected on the touch screen and the second touch input 202 is sequentially detected after a predetermined time elapses, an event associated with the resizing of the screen may be generated. It may be.

When an event related to the size adjustment of the screen is generated through the event generator 113, the trajectory tracking unit 114 may track the trajectory of the first touch input 201.

Then, the adjusting unit 115 may adjust the size of the screen displayed through the touch screen based on the tracked trace of the first touch input 201.

For example, when an event related to the resizing of the screen occurs through the event generator 113, the trajectory tracking unit 114 may track the trajectory of the first touch input 201 as shown by reference numeral 240. Can be.

In this case, the trace tracking unit 114 may ignore the trace of the second touch input 202. In other words, the trajectory tracking unit 114 may track only the trajectory of the first touch input 201.

Then, the adjusting unit 115 may adjust the size of the screen based on the trajectory of the first touch input 201.

In relation to this, in the example of 240, the adjusting unit 115 is displayed through the touch screen based on the trajectory of the first touch input 201 by tracking the trajectory of the first touch input 201 moving in the direction of the arrow. You can enlarge the screen size.

If the first touch input 201 moves in the direction opposite to the arrow direction in the example of 240, the adjusting unit 115 traverses the first touch input 201 moving in the direction opposite to the arrow direction. Based on the size of the screen can be reduced.

As a result, when the first touch input 201 is detected on the touch screen, and then the second touch input 202 is sequentially sensed, the touch screen device 110 according to an embodiment of the present invention, the first touch input By adjusting the size of the screen based on the trace of the first touch input 201 tracked by tracking the trace of 201, the user can easily adjust the screen size of the touch screen device 110 based on a simple touch input. To support them.

The operation of the touch screen device 110 according to an embodiment of the present invention has been described above with reference to FIG. 2. Hereinafter, the structure of the touch screen device 110 according to an embodiment of the present invention will be described with reference to FIG. 1.

According to an embodiment of the present invention, the touch screen device 110 may further include a center coordinate calculation unit 116.

The midpoint coordinate calculator 116 calculates midpoint coordinates between the coordinates of the first touch input and the coordinates of the second touch input when an event related to the size adjustment of the screen occurs.

At this time, according to an embodiment of the present invention, the adjusting unit 115 may include a trajectory calculating unit 117 and the size adjusting unit 118.

The trajectory calculator 117 calculates a movement trajectory of the midpoint coordinates corresponding to the trace of the tracked first touch input.

The size adjusting unit 118 adjusts the size of the screen based on the calculated movement trajectory of the center coordinates based on the center coordinates.

At this time, according to an embodiment of the present invention, the adjusting unit 115 may further include a first vector generator 119, a second vector generator 120, and a third vector generator 121.

The first vector generator 119 generates a first trajectory vector for the trace of the tracked first touch input.

The second vector generator 120 generates a second trajectory vector parallel to the generated first trajectory vector and having the same magnitude as the generated first trajectory vector using the midpoint coordinates as the starting point.

The third vector generation unit 121 generates a third trajectory vector symmetrical to the generated second trajectory vector based on the midpoint coordinates.

In this case, the trajectory calculation unit 117 calculates a first movement trajectory of the midpoint coordinates based on the direction and the magnitude of the generated second trajectory vector, and based on the direction and the magnitude of the generated third trajectory vector. The second movement trajectory of the coordinate may be calculated.

In this case, the size adjusting unit 118 may adjust the size of the screen based on the calculated first movement trajectory and the calculated second movement trajectory based on the midpoint coordinates.

Hereinafter, a process of adjusting the size of the screen by the adjusting unit 115 will be described in detail with reference to FIG. 3.

3 is a view for explaining a process of adjusting the size of the screen by the touch screen device 110 according to an embodiment of the present invention.

First, when the first touch input and the second touch input are sequentially sensed on the touch screen through the sensing unit 111, the event generator 113 generates an event related to the size adjustment of the screen displayed through the touch screen. Let's do it.

In this case, when an event related to the size adjustment of the screen occurs, the midpoint coordinate calculating unit 116 generates a coordinate between the coordinates A of the first touch input and the coordinates B of the second touch input, as shown at 310. The midpoint coordinates (C) can be calculated.

Then, when the first touch input moves, the locus tracker 114 may track the locus of the first touch input.

In this case, as illustrated at 320, the first vector generator 119 may generate a first trajectory vector 301 for the trace of the tracked first touch input.

Here, as illustrated at 320, the first vector generator 119 has a first trajectory based on the changed coordinate A 'of the first touch input and the coordinate A of the first touch input before the change. Vector 301 may be generated.

When the first vector generator 119 completes the generation of the first trajectory vector 301, the second vector generator 120 generates the first vector vector 119 using the midpoint coordinates C as a starting point. A second trajectory vector 302 parallel to the first trajectory vector 301 and having the same size as that of the first trajectory vector 301 may be generated.

Then, the third vector generator 121 may generate a third trajectory vector 303 that is symmetrical to the second trajectory vector 302 based on the midpoint coordinate C, as shown at 340. have.

When generation of the second trajectory vector 302 and the third trajectory vector 303 is completed, the trajectory calculator 117 moves the first point of the midpoint coordinate C based on the direction and the magnitude of the second trajectory vector 302. The trajectory may be calculated, and the second movement trajectory of the midpoint coordinate C may be calculated based on the direction and the magnitude of the third trajectory vector 303.

In this case, the size adjusting unit 118 may adjust the size of the screen based on the calculated first movement trajectory and the calculated second movement trajectory based on the midpoint coordinate C. FIG.

In the embodiment of FIG. 3, the size adjusting unit 118 is based on the midpoint coordinate C and the second trajectory vector 302 and the third trajectory vector based on the calculated first and second movement trajectories. The screen size corresponding to the size of the second trajectory vector 302 and the third trajectory vector 303 may be enlarged in the direction of 303.

As a result, the touch screen device 110 according to an embodiment of the present invention enlarges the screen based on the trajectory of the first touch input, but does not enlarge the screen based on the first touch input. The screen may be enlarged based on the midpoint between the touch input and the second touch input, thereby providing a screen magnification technique in consideration of user convenience.

In the above, the process of adjusting the size of the screen by the touch screen device 110 according to an embodiment of the present invention has been described in detail. Hereinafter, the structure of the touch screen device 110 according to an embodiment of the present invention will be described with reference to FIG. 1.

According to an embodiment of the present invention, the determination unit 112 may determine whether the detection of the first touch input and the detection of the second touch input through the detection unit 111 are stopped on the touch screen. .

In this case, when it is determined that the detection of the first touch input and the detection of the second touch input are interrupted on the touch screen, the event generator 113 may generate an event associated with stopping the resizing of the screen. have.

In other words, while the first touch input and the second touch input are sequentially detected on the touch screen, and the screen size is being adjusted, the determination unit 112 detects the first touch input and the second touch. If it is determined that the detection of the input is stopped, the event generator 113 may generate an event to stop the resizing of the screen, thereby preventing the screen from being resized.

In operation S410, a first touch input on the touch screen is detected.

In operation S420, when the first touch input is detected on the touch screen, it is determined whether the second touch input is sequentially detected on the touch screen after the first touch input is detected.

If it is determined in step S430 that the second touch input is not sequentially detected after the first touch input is detected on the touch screen, the step ( In S440, a command according to the first touch input is executed.

However, when it is determined in step S430 that the second touch input is sequentially detected after the first touch input is detected on the touch screen, step S450. ) Generates an event related to the resizing of the screen displayed through the touch screen.

At this time, according to an embodiment of the present invention, in step S420, the second touch is sequentially made after a predetermined time in a state in which the first touch input is maintained after the first touch input is detected on the touch screen. It may be determined whether an input is detected.

In this case, when it is determined in step S450 that the second touch input is sequentially detected after the predetermined time after the first touch input is detected on the touch screen, an event related to the resizing of the screen is generated. You can.
