BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

Although the first, second, etc. are used to describe various components, it goes without saying that these components are not limited by these terms. These terms are used only to distinguish one component from another. Therefore, it is needless to say that the first component mentioned below may be the second component within the technical spirit of the present invention.

In the present specification, when the same reference numerals are used to denote the same elements even when different reference numerals are used, the same reference numerals are used as much as possible.

It is to be understood that each of the features of the various embodiments of the present invention may be combined or combined with each other partially or entirely and technically various interlocking and driving is possible as will be appreciated by those skilled in the art, It may be possible to cooperate with each other in association.

In the present specification, when any one element 'transmits' data or a signal to another element, the element can transmit the data or signal directly to the other element, and the at least one other element Data or signal can be transmitted to another component.

In this specification, a touch screen refers to a device capable of receiving a signal through a screen by applying a minute current or pressure on the screen.

In this specification, an input is collectively referred to as all kinds of input detected by a touch screen. It is not only that the user physically touches the touch screen with an input tool such as a finger or a stylus, It can also be an input to make electrical contact by approaching.

A gesture input can be applied on a touch screen. In a gesture input, a tab means a method of lightly touching a hand or a stylus pen on a touch screen display to apply an input. , A multiple tap means a method of inputting three or more inputs within a predetermined time, and a long tap means a method of holding an input state for a predetermined period of time or until a specific event occurs, that is, a long tap. Depending on the nature of this gesture input, different events can be implemented to occur in the same application (or in the same mode in the application).

The input on the touch screen can be applied by various input methods. For example, in the case of a capacitive or pressure sensitive input method, the input may be applied only when a finger or a stylus pen touches or is adjacent to the touch screen display. On the other hand, when the electronic device further includes a digitizer panel together with a touch screen display, input through a capacitive or pressure-sensitive input method is applied on the touch screen, and input through a stylus pen interacting with the digitizer panel . That is, different events may be generated when the input through the digitizer panel is applied, such as the left click and right click of the mouse, and when the input by the capacitive or pressure sensitive input method is applied. Further, in addition to the digitizer panel, different events may be generated according to the input method in the same application (or the same mode in the application) through a device capable of sensing input through various sensors and detecting coordinate information.

As used herein, the command input area refers to an area such as a keypad or a touch keyboard for providing convenience to the user, which is displayed on a touch screen in a device having a touch screen or displayed in a designated space so that input is possible.

In this specification, a terminal refers to a device such as a computer having a touch screen, a smart phone, a note pad, a notebook, and a tablet PC, and is not limited to a specific device as long as it is a device implemented to be able to input and output through a touch screen.

Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

1 is a block diagram of an algorithm for controlling an instruction input area on a touch screen according to an embodiment of the present invention.

Referring to FIG. 1, an apparatus 100 for controlling a command input area on a touch screen includes a touch screen 110, a receiver 120, and a controller 130, according to an embodiment of the present invention.

Here, the command input area control device 100 on the touch screen may be included in or connected to a device such as a computer having a touch screen, a smart phone, a note pad, a notebook, and a tablet PC, have.

First, when the touch input is applied through the touch screen 110, the receiving unit 120 receives the input coordinates of the input applied through the touch screen. At this time, the receiving unit 120 can receive a plurality of input coordinates, and in order to control an instruction input region on the touch screen according to the present invention, at least two input coordinates must be received. More specifically, since the command input area is determined by the control unit 130 to be described later on the basis of the distance between the input coordinates received by the receiving unit 120, at least two input coordinates are required, May vary.

For example, an input can be applied to two coordinates based on the thumb and the base of the user's finger, and the input can be applied to five coordinates corresponding to the five finger end points with the palm extended. The user may apply the input to the coordinates of the area where the finger touches the touch screen while holding the terminal in such a manner that the finger touches the touch screen 110 in a scanning manner.

According to an embodiment of the present invention, a distance between coordinates may be detected based on at least one input coordinate input through a touch screen and at least one coordinate on a predetermined touch screen. For example, when the user inputs one input on the touch screen, the distance may be calculated based on an area formed based on a predetermined standard coordinate of an area outside the touch screen display of the terminal. In this case, distance detection may be possible by inputting one coordinate.

When the input coordinate is received by the receiver 120, the controller 130 detects the distance between the input coordinates and determines the command receiving area on the touch screen based on the position of the input coordinate and the maximum distance between the input coordinates. The control unit 130 determines the position based on the direction of the terminal and the display screen, and the reference for determining the maximum distance between the input coordinates includes the maximum distance of the horizontal axis and the maximum distance of the vertical axis, Maximum distance is also included. Further, the maximum distance of the horizontal axis may be the maximum distance of the vertical axis or the maximum distance of the diagonal line depending on the direction in which the input is applied on the touch screen, and the maximum distance of the vertical axis and the maximum distance of the diagonal line may be the maximum distance of the horizontal axis, It can be a relative maximum distance.

When the input is applied in such a manner that a finger touches the touch screen in a state where the finger is held while holding the terminal, the control unit 130 similarly controls the input coordinates And determines the maximum distance between the input coordinates including the maximum distance between the horizontal axis and the vertical axis, and the maximum distance between the coordinates at both ends of the diagonal line based on the coordinates of the outermost one of the plurality of coordinates. A criterion for determining the position of the input coordinates and the maximum distance between the input coordinates when the input is applied in such a manner that the finger touches the touch screen in a state in which the finger is held while holding the terminal is scanned, will be described later in detail with reference to FIG.

When the position of the input coordinates and the maximum distance between the input coordinates are detected, the control unit 130 determines the command input area on the touch screen according to a preset value based on the position and the maximum distance. In this case, the predetermined value is a value for determining the command input area based on the coordinate position and the maximum distance, and the maximum distance between the input coordinates and the determined command input area do not necessarily match. More specifically, the maximum distance between the input coordinates and the abscissa of the command input area is not necessarily determined to be equal to each other. The distance is proportional to the maximum distance based on the position and the maximum distance, The area of the command input area can be determined by adding or subtracting.

Figure 2 illustrates a flow diagram of a method for controlling an instruction input region on a touch screen in accordance with an embodiment of the present invention. Will be described with reference to Fig. 1 for convenience of explanation.

First, the receiving unit 120 receives input coordinates of two or more inputs applied to the touch screen 110 (S100). At this time, the input collectively refers to all kinds of input detected by the touch screen. The user not only physically touches the touch screen with an input tool such as a finger or a stylus, but also approaches the proximity distance It is also possible that an electrical contact is made. The problem to be solved by the present invention is to improve the convenience of the user by providing an optimized command input area in the user's hand so that the determination of the command input area must be determined by the size of the user's hand or body part And the command input area can be determined by the inputted input using the input tool.

If two or more input coordinates are received by the receiver 120, the controller 130 detects the position of the input coordinates and the distance between the input coordinates (S110). The control unit 130 detects the distance between the input coordinates and detects the maximum distance between the horizontal axis, the vertical axis and the diagonal line. The reference for determining the maximum distance between the horizontal axis, the vertical axis and the diagonal line is determined as the position of the input coordinate do. 1, the maximum distance of the horizontal axis may be the maximum distance of the vertical axis or the maximum distance of the diagonal line, and the maximum distance of the vertical axis and the maximum distance of the diagonal line may be the maximum Distance and the relative maximum distance corresponding to each.

More specifically, since there is a difference in the size and resolution of the display area according to the user terminal, in determining the maximum distance, the ratio of the maximum distance determines the horizontal and vertical directions of the command input area It can be a standard. For example, if a terminal having a horizontal axis is longer than a vertical axis and a user inputs an input to two input coordinates vertically and vertically on the touch screen, if the command input area is determined to be displayed only vertically long, And the display area may be inefficient. In determining the maximum distance direction of the input coordinates according to the user terminal, the size of the display area of the terminal, the ratio of the horizontal axis to the vertical axis of the display area, And the ratio of the maximum distance of the input coordinates can be a reference for determining the direction.

After detecting the position of the input coordinates and the distance between the input coordinates (S110), the controller 130 determines the command input area based on the position of the input coordinates and the maximum distance between the input coordinates (S120). At this time, when the maximum distance between the input coordinates is less than a preset value, the control unit 130 can determine the command input area as a settable minimum size. If the maximum distance between the input coordinates is equal to or larger than a preset value, It is possible to determine the maximum possible size. The predetermined value is a value for determining the command input area based on the maximum distance as described above with reference to FIG. 1, and is a value that is proportional to the maximum distance based on the maximum distance, or a value obtained by adding or subtracting a certain value to the maximum distance Lt; / RTI >

Herein, when the maximum distance between the input coordinates is less than a predetermined value, the control unit 130 determines that the command input area determined based on the maximum distance is smaller than the minimum size of the command input area settable by the user terminal. If the maximum distance between the input coordinates is equal to or larger than the preset value, the command input area determined based on the maximum distance is determined to be smaller than the maximum size of the command input area settable by the user terminal In this case, the controller 130 may determine the command input area to be the maximum size that can be set.

In addition, the control unit 130 may store one or more determined command input areas according to a user or a designation of a user. For example, when a plurality of users use one terminal, a plurality of users determine a command input area according to the size of each user's hand and store the command input area, It is possible to invoke the setting corresponding to the determined command input area and use it because the size of the command input area required by the user may be different depending on the situation.
