It is an object of the present invention to provide a method of simplifying a command inputting procedure of a user for updating the content displayed on an output screen (or a monitor) of a terminal by enlarging / reducing / moving.

The present invention as a technical means for solving the above problems is characterized in that at least one identification area which can be defined as an arbitrary partial area of the touch screen is set at an arbitrary position and the input operation of one hand Wherein at least one of the identification areas is set as a drag magnification area (500a) in each of the operation processes corresponding to at least one input signal (contact / contact release / click / drag operation signal) When the drag operation signal is generated by the input operation (630d, 631d, 640d) and the position 420p where the last generated contact signal belongs is within the drag magnification area 500a, the direction of the drag operation signal is referred to as the contact signal 420p, (630d, 631d), the current operation state value is changed to the magnification mode, and when it is the other direction (640d), the operation mode is changed to the movement mode And at least one of the identification regions is set as a drag movement region 410a so that a position 411p at which the last generated contact signal at the time of generating the drag operation signal 620d or 421d belongs to the drag movement An operation procedure for changing the current execution state value to the movement mode in the region 410a is defined in advance and at least two of the identification regions are set as the click expansion region 512a and the click reduction region 511a, And defining an operation procedure for performing a magnification change command when a click signal generated by the input operation is located within the click enlargement area 512a or the click reduction area 511a.

Also, in order to clearly determine an input signal generated when the identification areas are crossed / duplicated with each other by a command required by the user, a priority order is defined in each of the identification areas, and when the current execution state value is a standby mode By selecting and comparing the start position of the input signal generated by the input operation and sequentially comparing and determining the identification region defined in the operation sequence corresponding to the generated input signal according to the priority order, When the current operation state value is not in the standby mode (s710, s720), when the drag operation signal is generated (s700), the corresponding command is executed (s740) ) The command corresponding to the current execution state value is repeatedly executed (S740).

FIG. 3 is an exemplary view showing contents of a touch screen updated as a result of performing a move command and an enlargement / reduction command in an input operation through a touch screen;

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, a display device (hereinafter referred to as " touch screen ") configured to include an input device capable of inputting any one point of a display device by directly touching and / A predetermined input tool capable of pointing at an arbitrary point on the screen of an output device such as a smart phone or a personal computer or the like and / A method of simplifying an input procedure of a command for updating the contents displayed on the touch screen will be described.

That is, the predetermined input tool refers to an input tool capable of generating an input signal by pointing at an arbitrary point on a touch screen (hereinafter referred to as "one-handed rhythm"). For example, a 'mouse' used as one of ordinary input devices of a personal computer may be included in the meaning of the one-handed melody as an input tool.

A preferred embodiment of the present invention is a smart phone having a touch screen device mounted thereon. For example, the smart phone may include an application program that can be implemented in an application program development language of a smartphone operating system, Explanations and examples of detailed source code are omitted. Thus, the term " file " used throughout this specification refers to a set of data stored in a storage device (memory, hard disk) of a computer system.

The description of the present invention will now be given, after describing the individual components (functions) of the present invention with reference to FIG. 1, further describing the correlation between the individual components with reference to FIG. 2, I will explain the purpose.

FIG. 1 illustrates an example of some input operations (touch, click, drag, etc.) caused by one-handed touches that may occur on a touch screen mounted on a smart phone according to an exemplary embodiment of the present invention, An example of expressing the "identification area" for identifying the user command with the type and position of the signal inputted through the screen by defining the area and the width on the touch screen and the example of displaying the display area 100a on the entire Region.

That is, the identification area is an arbitrary partial area on the touch screen that can be defined as a position and a width, and an operation process corresponding to input signals generated in each identification area is defined differently according to each identification area, It is possible to clearly identify the command required by the user by performing the operation process defined in the identification area corresponding to the input signal generated at an arbitrary position on the screen.

In the description of the present invention, the identification areas include a "dragging area" 410a, a "dragging area" 500a, a "click reduction area" 511a and a "click enlarging area" 512a, The definition of the operation process corresponding to the input signal generated in each will be described in detail later.

The display area 100a is an area on a touch screen in which components recorded in an arbitrary file or / and data are displayed in a display method desired by the user.

Therefore, it is preferable that the content displayed in the display area 100a is displayed in a picture format if the data structure of the file to be displayed is a format in which the image is recorded, and in a character format if the format is text format.

Hereinafter, in order to explain the structure of the present invention smoothly, a part or all of the elements in a data file (hereinafter referred to as an "image file") including pixel information data in which image information is recorded, Quot; exposed area "to display on the touch screen, thereby explaining the gist of the present invention. That is, a method of accessing the positions of the respective components by a two-dimensional or three-dimensional area coordinate system regardless of the data format recorded in the data file will be described.

For example, in a plane coordinate system, the position coordinate value of the first pixel element of the image file can be expressed as '0, 0', and the position coordinate value of the last element can also be expressed as 'x, y' And a value corresponding to x and y may be changed according to the size of the image file.

The exposed region is a data set in which elements are recorded in the image file for display in the display area 100a. That is, the exposed portion may be all or a part of the components of the image file.

The "area frame" is information of one area defined by the area coordinate system. Therefore, by defining / changing the information of the area frame, the exposed part can be selected as the elements belonging to the area frame among the elements of the image file converted into the area coordinate system.

That is, the elements of the image file converted into the area coordinate system belonging to the inner left determination values of the area defined by limiting the size (range / area) of the area frame and by setting the center coordinates as the reference point, You can select by size or position.

Accordingly, the "magnification change command" can be obtained by multiplying or dividing the current magnitude of the region frame by a predetermined magnification value, without changing the current center left reference value, which is the reference of the region frame, It is a command to select the enlarged / reduced size.

In addition, the "movement command" is an instruction to change the current center coordinate value of the area frame to the coordinate value of another position in order to change the position of the previously selected exposed part.

'Z00' and 'z01' in FIG. 3 are scaled by displaying the content of the area frame including the changed exposure area by scaling the magnification change command (enlargement / reduction) (Enlargement / reduction) of the image 100a.

M00 'in FIG. 3 is an example of displaying an existing selected exposed part in the image display area,' m01 'indicates the contents of the area frame including the exposed part changed by the movement command, The display area is updated by scaling the display area.

Examples of the type / form of the 'input signal' include a 'touch operation' for generating a 'touch signal' by an operation of attaching a one-handed touch to the touch screen, Quot; contact release operation "for releasing the one-handed touch on the touch screen after a predetermined period of time after the generation of the touch signal to generate a" contact release signal ", a position of the one- Quot; click action " that generates a "click signal" at the moment when the one-hand touch is released and the one-hand touch is released within the predetermined time without touching the other touch "And so on.

The number of times of the drag signal that can be generated by one drag operation by one hand on the touch screen may vary depending on the length of the drag operation.

Therefore, it is not preferable that all of the generated drag signals are judged to be a user command because the fine positional change of the drag signal generated during the drag operation may not be a drag signal generated according to the user's intuitive input operation.

Therefore, a drag signal corresponding to the number of times the remainder becomes " 0 "by dividing the cumulative number of the drag signals generated while the drag operation continues from the position where the contact signal is generated by the one- The structure of the present invention will be described.

For example, the predetermined constant may be defined as a different value depending on whether the current command requested by the user is a move command or a magnification change command, and the arrows 620d, 631d, 640d are examples of the number and position of the number of times the drag operation signal is generated by the number of dashed lines. For example, an arrow 630d drawn with a dashed line in FIG. 1 is an example in which five drag operation signals are generated.

1, an operation process corresponding to an input signal that may occur on a touch screen is divided into a drag movement area 410a, a drag magnification area 500a, a click reduction area 511a, And the identification areas are set at an arbitrary position on the touch screen by the touch panel 512a.

Each of the identification regions may be defined as an area in which one identification region intersects with another identification region or is included in another identification region. 1 shows an example of a case where the drag magnification area 500a is defined as an area where the click reduction area 511a and the click enlargement area 512a and the drag movement area 410a are intersected and included with each other Lt; / RTI >

In addition, it is preferable that each of the identified identification regions is further defined to be another size or the same size at another position on the touch screen, if necessary.

Also, the identification areas defined on the touch screen may be displayed on the touch screen to guide the user's input operation. However, when the identification areas are defined in the image display area, it is preferable not to display them.

The user performs an operation corresponding to the input signal generated in the identification area to which the start position (contact signal / click signal) of the generated input signal belongs by performing the input operation by one-handed rhythm through the touch screen, Can be input.

Each of the identification regions can perform a processing procedure corresponding to an input signal generated only when an operation process in the corresponding region receives a predefined input signal. For example, if the generation position of the click signal belongs only to the drag movement region 410a, the process proceeds to the next step without performing any processing.

The "performance state" has a value of a state of a command that the current user is requesting, and the state value may be changed according to an input signal generated by the input operation of the one-handed rhythm.

That is, the status value that the execution status can have is only described for the status values for the "magnification mode", "moving mode", and "standby mode" in the description of the present specification. Among these status values, the standby mode is a value indicating a state in which a command requested by the user is a terminated state and a state in which a new command is simultaneously waiting.

If the current execution state is not the standby mode, a command (movement command or magnification change command) corresponding to the execution state is repeated every time a drag operation signal is generated.

Further, when a contact release signal or contact signal is generated, the current execution state is changed to the standby mode.

Each of the click enlargement area 512a and the click reduction area 511a may be configured to previously define an operation process corresponding to the click signals 521c and 522c generated in the identification area, .

For the sake of reference, the meaning of 'applying the magnification constant value' means that when the magnification change command is executed, the horizontal and vertical magnitude values of the area frame are multiplied or divided by the magnification constant value to change the size / area of the area frame. The 'magnification constant value' can be divided into a 'click magnification value' and a 'drag magnification value' which will be described later in detail.

For reference, the click signal generated in the click enlargement region reduces the size / width of the region frame when performing the magnification change command, and the click signal generated in the click enlargement region 511a enlarges the size / width of the region frame It is desirable to define.

The 'condition', which can be changed from a state in which the current execution state is the standby mode to another value, can be defined as a case where the drag operation signal is generated for the first time in the state of being in the standby state in the drag movement region or / have. At this time, by performing an operation process corresponding to the input signal defined in the identification area to which the start position of the drag operation signal that occurred first (i.e., the position where the last generated contact signal is generated) belongs, The value of the state can be changed from the standby mode to another value (magnification mode or moving mode).

That is, when the last position 411p of the contact signal belongs to the dragging region 410a, the operation to change the current performing state to the moving mode is performed in the dragging region 410a Is defined in advance as an operation process corresponding to the input signal generated by the input operation of the one-handed melody (411p) started from the one-handed melody.

If the last position 420p of the touch signal belongs to the drag magnification area 500a in the 'condition', the position of the drag operation signal signal currently generated based on the position of the touch signal s420 (630d, 631d) if it is determined to be in a predetermined direction (enlargement / reduction direction), the process of changing the current execution state to the magnification mode and the other mode to the movement mode is performed in the drag magnification area 500a The operation process corresponding to the input signal generated by the input operation of the one-handed melody that has been started (420p) is defined in advance.

That is, when the drag operation signal is generated in the state where the current operation state value is in the standby mode, an operation process corresponding to the contact signal defined in advance in the identification region (drag movement region or drag magnification region) The execution state is changed and a corresponding instruction is executed. Thereafter, every time a drag operation signal is generated, the user instruction corresponding to the current execution state is repeated.

The direction of the drag operation signal which is based on the contact signal 420p and / or the generation position of the immediately preceding input signal is 26 seconds The direction of the drag operation signal in which the direction of the drag operation signal is less than 35 seconds and the direction of the drag operation signal is in the enlargement direction 630d and in the opposite direction (between 55 seconds and 60 seconds and 5 seconds) can be defined as the reduction directions 631d and 632d .

In other words, in defining the predetermined direction, each direction can be defined as a range in which the enlargement direction and the reduction direction can not intersect with each other, but it is preferable to define them in the opposite directions.

In addition, when the current execution state value is not the standby mode, the direction of the drag operation signal currently generated during the drag operation of the one-hand rhythm can be determined based on the position of the drag operation signal generated immediately before. For example, it can be judged that the drag operation in the downward direction is a drag operation at the position where the drag operation 630d in the enlargement direction changes to the opposite direction 632d.

As described above, each of the identification areas can be defined by being intersected with each other at an arbitrary position on the touch screen or included in another identification area. Particularly, in the drag magnification area 500a and the drag movement area 410a, Contact signal, drag operation signal) are predefined.

Therefore, in order to process an input signal generated at an arbitrary position of the touch screen image in which two or more identification areas are overlapped with each other and / or intersected with each other to determine a command required by the user, It is possible to clearly determine the user command by defining the priority order of each identification area for judging a defined identification area and comparing / judging in order and performing the operation procedure defined in the corresponding identification area.

For example, when a drag operation signal is generated when the current execution state value is in the standby mode, the determination order of the identification region to which the position of the immediately preceding contact signal belongs is compared / compared in the order of the drag magnification region 500a and the drag movement region 410a. The execution state can be clearly changed by performing only an operation process corresponding to an input signal that is predefined in the corresponding identification region.

Referring to the operation procedures corresponding to the input signal defined in each of the identification regions described above, each of the click and drag operations of the one-handed rhythm can cause a magnification change command. At this time, it is preferable that, in performing each of the magnification change commands generated by the click operation or the drag operation, different magnification values are applied, and the magnification change command corresponding to each magnification change command is changed to change the exposed part.

For example, as described above, the one-hand click action 522c within the click enlargement area 512a performs a magnification change command irrespective of the current execution state value. At this time, the magnification change command for changing the magnification The drag operation signal generated when the current run state value is in the scaling mode may also lead to the execution of the scaling change command. In this case, the size of the area frame is defined as " 2 " (Hereinafter referred to as "drag magnification value"), the size of the area frame changed to the magnification change command to which the drag magnification value is applied is set to be relatively precise do.

FIG. 2 is a flowchart showing an organic operation process of some of the configurations described with reference to FIG.

For reference, as described above, the configuration of the present invention can be explained as a process of configuring an application program executable in a smart phone. Therefore, the subject related to the input / output / storage (memory) etc. is a part which can be explained within the scope of a normal software development method (source code creation) of the terminal, and the detailed description of the subject blurs the essence of the following explanation I will not include it within the limit. For example, a memory-related subject means a main memory or similar information storage device that corresponds to a computer configuration, not a human head.

Hereinafter, with reference to the flowchart of FIG. 2, a description will be given of a process of determining a command requested by a user by performing an operation process corresponding to an input signal generated by an input operation of a one-handed rhythm to update a display area .

In the start step (s100), the position and the width of each of the identification areas are defined on the touch screen, and the content (information) of the area frame capable of including the exposure part to be output in the display area is scaled and displayed. In addition, the initial value of the execution state is set to the standby mode, and the flow advances to the next step (s200).

For reference, the identification areas may be defined in any area of the touch screen outside the display area. However, in the example of the drawings (FIG. 1) referred to in the present invention, it is understood that the identification areas are defined inside the display area have.

The next step (s200) is a step of monitoring a user input signal that may occur in the touch screen by the input operation of one-handed rhythm, and holds the input signal standby s200 until the end signal s900 occurs.

The touch signal s400, the touch release signal s500, the click signal s600, and the drag operation signal s600 according to the result of analyzing the signals generated by the input operation of one-handed rhythm in the input signal standby state s200 s700). < / RTI >

At this time, it is preferable that the 'condition' of the drag operation signal s700 is set differently from the condition for identifying the drag operation signal depending on whether the current operation state value is the movement mode or the magnification mode.

The 'condition' is, for example, a 'constant value' for dividing the cumulative number of generated drag signals, which is mentioned in the content of the definition of 'drag operation signal' in the description with reference to FIG. 1, Can be set to be different from each other.

If the input signal generated on the touch screen is the contact signal s400 and / or the contact release signal s500, the current execution state is initialized (s410) to end the current instruction, and the current execution state is changed to the standby mode do.

Hereinafter, for the sake of a better understanding of the explanation, the "click magnification area" is defined as either the "click reduction area" 511a or the "click enlargement area" 512a of the identification areas. Therefore, the input signal generated in the click magnification area is an input signal generated in either the click magnification area () or the click enlargement area 511a.

If the click signal has occurred, it is determined whether the generated position is within the click magnification areas 511a and 512a (s610). If the click signal is generated, the current execution state is changed to the standby mode (s410) The magnification change command is applied with the click magnification value applied (s740).

When a drag operation signal is generated on the touch screen (s700), the exposed region can be changed by executing an instruction corresponding to the current execution state value (s710 or s720) (s740).

At this time, when the corresponding command is a magnification change command, it is preferable to apply a magnification change command by applying a drag magnification value.

However, when there is no instruction currently being executed when the drag operation signal s700 is generated, that is, when the current execution state is the standby mode, the value of the current execution state for determining the instruction corresponding to the drag operation signal is changed (s730) And then executes an instruction corresponding to the current execution state value (s740).

At this time, the execution of the instruction corresponding to the execution state value (s740) is the execution of the magnification change instruction or the movement instruction to change the exposed region, and the content of the changed region frame is displayed And scales the area to update the display area.

As described above with reference to FIG. 1, the 'condition', which can be changed from a state in which the current execution state is the standby mode to another value, is a state in which the current state is set in the drag movement region or / and the drag magnification region, It can be defined as when a drag operation signal occurs.

If the 'condition' occurs, as described above with reference to FIG. 1, by performing an operation process corresponding to the input signal defined in one identification area to which the position of the immediately preceding contact signal s400 belongs, The current execution state can be changed to a value corresponding to the requested command (S730).

In the step of performing the command corresponding to the request of the user inputted through the touch screen in the input operation of the one-handed rhythm (s740), the instruction corresponding to the click signal S600 or corresponding to the current execution state is judged, Command / move command is executed (S740).

When the current execution state value is the standby mode and the start position (position of the contact signal) of the first generated drag operation signal does not belong to the drag magnification area 500a and the drag movement area 410a, In step s730, the current execution state is not changed, and in the step of performing the corresponding instruction in the next step (s730), the process advances to step s750 of updating the display area without performing any processing.

For reference, in the example of FIG. 1, an area between 500L and 511L is an area where the drag moving area and the click magnification area intersect.

In the step of updating the display area (s750), it is preferable to determine whether the information of the area frame has been changed, and to update the display area by scaling the configuration information of the area frame in the display area only when the information is changed.

The contact release signal s500, the click signal s600, and the drag operation signal s700 as well as the contact signal s400 memorize the position and the input pattern generated after performing the corresponding operation process (s760) If necessary, it can be used as a criterion to compare with the current input signal that has occurred again.

The current value of the execution state is maintained until the next contact signal s400 or the contact release signal s500 is generated and the corresponding command is repeated when the current value of the execution state is not in the standby mode every time the drag operation signal s700 is generated (S740).

If the input signal generated on the touch screen is the drag operation signal s700 and the current execution state value is the movement mode s710, the movement command is executed in the next step s740. At this time, it is preferable to determine a direction based on the position of the immediately preceding input signal (s760) and to perform a movement command to change the center point left turn mark value of the area frame to a direction opposite to the determined direction.

When the drag operation signal s700 is generated on the touch screen, if the current operation state value is the magnification mode s720, the size / size of the area frame is determined based on the position of the input signal generated immediately before (s760) And performs a magnification change command to enlarge or / or reduce the width. That is, according to the enlargement / reduction direction determined based on the position of the immediately preceding input signal s760 as described with reference to FIG. 1, a magnification change command is applied to apply the drag magnification value, do.
