Title: The system and the method for giving contents in the smart phone

Description:
TECHNICAL FIELD 
     The present disclosure relates to a system and method configured to provide information within a text service of a smartphone and, more particularly, to a system and method that may provide a method of an operation command capable of providing various programs or content as well as information within the text message service. 
     BACKGROUND ART 
     A touch screen or touch panel refers to a user interface device that allows a user to directly touch text or a specific position on a screen with his or her finger or any optional operation means without using a keyboard, so as to detect the touched position and process an operation of the touched position through prestored software. As an example, touch panel types include: a resistive overlay type, a surface acoustic wave type, a capacitive overlay type, an infrared beam type, etc. 
     In addition, due to such various types of touch input devices as described above, a desired operation command may be directly executed on a display, and in practice, as functions of text services diversify, the role of the input function through such a touch screen or touch panel is growing. 
     However, since a lot of information is interrelated on a display of a today&#39;s terminal, a detailed method for effectively displaying the information different from and interrelated with other information currently displayed on the display is not yet proposed. 
     That is, in Korean Patent Application Publication No. 10-2017-0029466, “A method for providing content realized by a computer”, there is provided the method for providing the content, the method including: registering the content in a form of a conversation according to a time flow by receiving data input in a form of a timeline from a terminal of a first user, matching each piece of the data with corresponding time information, and storing the data; receiving a request for access to the content from a terminal of a second user providing a messenger chat interface between a messenger account of the second user and a messenger account that is related to the content according to the request for the access; and providing the content so that the data included in the content may be sequentially reproduced over time on a screen of the terminal of the second user in an order of the time flow corresponding to the matched time information through the messenger chat interface. 
     In addition, in Korean Patent Application Publication No. 10-2017-0138682, “A content management method of a messenger server that manages DRM (Digital Right Management) content in connection with a DRM server”, there is provided a method for managing the content including: establishing a messenger chat session between an account of a first user and an account of a second user, who are registered as members; checking whether the content received from an electronic device of the first user is the DRM content managed in association with the DRM server according to content upload through the messenger chat session of the first user, changing user identification information of a license included within the DRM content from identification information for the first user to identification information for the second user through association with the DRM server when the uploaded content is the DRM content; and providing the DRM content in which the user identification information has been changed, so as to be shared with the second user through the messenger chat session. 
     However, it is not that the above patented technologies suggest the method of effectively providing various content and information, which are provided by a text service, and various programs provided by a smartphone. 
     Therefore, when users use the text service, there is an urgent need to develop a system and method that effectively provides various content and information, which are provided by the text service, and various programs provided by the smartphone. 
     Related Art 1: Korean Patent Application Publication No. 10-2017-0029466 (published on Mar. 15, 2017) 
     Related Art 2: Korean Patent Application Publication No. 10-2017-0138682 (published on Dec. 18, 2017)

     Hereinafter, exemplary embodiments according to the present disclosure will be described in detail with reference to the accompanying views. The configuration of the present disclosure and the effects thereof will be dearly understood through the following detailed description. 
     In addition, detailed descriptions of well-known technical configuration may be omitted. 
     In the present disclosure, a “stepwise operation command” is executed within a text service of a smartphone, so as to provide various content and information, which are provided by the text service, and various programs provided by the smartphone. 
       FIG. 1  is a view illustrating a configuration of a smartphone connected to a server through a wired/wireless Internet. 
     A server  100  in a communication system is a device constituting a system that operates various types of information provision services over the wired/wireless Internet. The server  100  includes: an input part  103  configured to allow a manager or operator of the server  100  to input and manage information; an output part  105  configured to output or display the information (i.e., the output part includes a connection port, a printer, and the like for outputting the information); a database  104  for storing various types of information and information related to the operation of services; and an interface part  102  capable of transmitting and receiving data to and from an accessing user over the Internet or a communication network. Meanwhile, the information refers to all types of information including an image, a video, text, etc. 
     In addition, a smartphone  110  (or portable terminal) is a terminal capable of transmitting and receiving various types of information over the wired/wireless Internet (or communication network). 
     Therefore, the smartphone  110  is configured to include: a central processing unit (CPU)  20 ; a display  30  for displaying various types of information; a memory part  21  for storing various types of the information; an input device  28  for inputting the information; and a data input/output part  10  for inputting/outputting data or the information. 
       FIG. 2  is a block diagram illustrating the server in more detail. 
     A controller  101  is configured in the server  100 , and includes a data search part  111  configured to search for data, a data processing part  112 , and a site operation part  113  configured to manage and operate Internet-accessing users or Internet members.

     In addition, the above-described controller  101  and the database  104  are merely examples, and it may be considered that any conventional controller for performing all algorithms for server operation and any conventional database for storing all types of information may be included in the exemplary embodiment of the present disclosure. 
     Meanwhile, in the controller  101  of the server  100 , the site operation part  113  determines information about an accessing user (or smartphone) and information about memberships and use of content, the data search part  111  searches the database  104  for information that matches the information transmitted from the accessing user (or smartphone), and the data processing part  112  transmits the results of performing the algorithms and the retrieved data to the accessing user through the interface. 
       FIG. 3  is a view illustrating a block diagram of a portable smartphone. 
     In the view, the central processing unit  20  is a control means for controlling the entire operation of a portable smartphone (that is, generally, a portable display device, a smartphone, or a computer) used in the exemplary embodiment of the present disclosure. In addition, read only memory (ROM)  21   a  that is present in the memory part  21  (or  21   a,    21   b,  or  21   c ) controls execution programs of the display device, random access memory (RAM)  21   b  stores data generated during the execution of the programs, and electrically erasable programmable ROM (EEPROM)  21   c  stores data required by a user and data required to process the data required by the user. 
     A radio frequency (R/F) part  24  is configured to tune to an RF channel with a radio frequency, amplify various types of input signals, and convert the RF signals received through an antenna into required frequency signals. The input/output part  10  includes an input part and an output part, wherein the input part includes various types of information input devices, numeric keys, menu keys, and selection keys, and the output part includes a speaker, a vibrating device, or the like. 
     There is provided a display driving circuit  25  for receiving signals output from the central processing unit  20  and driving the display, wherein the display driving circuit outputs the signals capable of driving a display  30 . 
     In addition, the central processing unit controls the input device  28  through an input device driving part  27 . That is, when information is input through the input device  28 , the input device driving part transmits the input information to the central processing unit. 
     Meanwhile, the portable smartphone of the present disclosure may include a portable display device, a smartphone, a tablet PC, etc. 
       FIG. 4  is a view schematically illustrating a conventional input device and an input device driving part. 
       FIG. 4  is the view schematically illustrating a sectional view of the input device, wherein  FIG. 4(A)  is a view showing a capacitive type input device and  FIG. 4(B)  is a view showing a resistive film type input device. 
     That is, in  FIG. 4(A) , an electrode plate  29   a  coated with a transparent electrode is provided under a protective plate  28   a,  and the electrode plate  29   a  is composed of one or two sheets of films, each coated with the transparent electrode. 
     In addition, in  FIG. 4(B) , two films  29   a  and  29   b,  each coated with the transparent electrode, are provided on an upper part of the protective plate  28   a  so as to face each other in a state of maintaining a predetermined distance spaced apart from each other, and an external protective plate (or a decorative plate)  28   b  may be further provided on an upper end of the input device  28 . In addition, a coating having a desired pattern is applied to the protective plate  28   b.    
     In addition,  FIG. 4  illustrates an example of the input device  28  that is conventionally and widely used, but the present disclosure is not an invention for the input device  28 . Therefore, any conventional input device  28  capable of inputting information on the display may be applicable to the present disclosure. 
     In this case, the term “on the display” means that information may also be able to be input in a state where no pressure or contact is applied to the surface of the display. 
     In addition, the exemplary embodiment of the present disclosure may be applied to a device in which an input device and a display are integrated with each other. 
     Meanwhile, as long as information may be input by distinguishing steps from each other even through an image change or motion change, such an image change or motion change may be applicable to the exemplary embodiment of the present disclosure. 
       FIG. 4(C)  illustrates an exemplary embodiment of the input device driving part.  FIG. 4(C)  is a view merely illustrating an exemplary embodiment, and the present disclosure may use any type of conventional input device driving part. 
     A touch input driving part  50  according to the exemplary embodiment of the present disclosure includes a calibration function execution part  51 , an average value detection count adjustment part  52 , an average value detection part  43 , a panel signal generation part  54 , etc. 
     In addition, it may be considered that the input device driving part of the present disclosure is merely an exemplary embodiment and a conventional input device driving part is included in the configuration of the present disclosure. 
     The calibration function execution part  51  performs calibration on the coordinate values of the touch input part  72  when a device is initially operated. In accordance with this calibration function, panel signals corresponding to the coordinate values of an actual position that is touched on the touch input part  72  are selected. That is, the signals of the touch input part  72  corresponding to coordinate values are selected according to the resolution of a touch display  74 , and the selected signals are provided to a controller  30 . 
     Accordingly, the controller  30  stores and manages the coordinate values corresponding to the panel signals. The average value detection count adjustment part  52  adjusts an average value detection count of the panel signals output from the touch input part  72  on the basis of screen resolution information of the touch display  74 , the screen resolution information being provided from the controller  30 . When the screen resolution is changed to high resolution, the average value detection count is adjusted to a value greater than the value that is previously set. Conversely, when the screen resolution is changed to low resolution, the average value detection count is adjusted to a value less than the previously set value. 
     An average value detection part  53  detects an average value of the panel signals transmitted from the touch input part  72  on the basis of the average value detection count adjusted by the average value detection count adjustment part  52 . In addition, the average value detection part  53  transmits the detected average value to the panel signal generation part  54 . 
     The panel signal generation part  54  generates the panel signals by using the changed screen resolution, provided from the controller  30 , of the touch display  74 , or by using the average value of currently input panel signals and the position information, changed by a virtual scroll, of the display screen. 
     When a user touches a certain point with one or two fingers or with any operation means, the touch input driving part  50  configured in this way continuously detects the position information of the touched point a predetermined number of times, and then outputs the average value of the detected values as the final position information. 
       FIG. 5  is a view illustrating an exemplary embodiment in which a stepwise operation command is executed through the input device. 
     As shown in the exemplary embodiment of  FIG. 5 , the stepwise operation command is executed by using a small bar or using fingers on the display  30 . 
     That is, the stepwise operation command is input by selecting information displayed on the display through the input device  28 . As shown in  FIG. 5 , the stepwise operation command is executed by a method of reducing or increasing a distance between points selected by using two fingers (or bars). 
       FIG. 6  is a view illustrating another exemplary embodiment of executing the stepwise operation command through the input device. 
     By using fingers (or bars) as in  FIG. 6 , an upper end of the display  30  is selected in the smartphone  110 , and the length of holding time after selecting is adjusted, whereby the stepwise operation command is executed. 
     For example, an area within the display  30  where the stepwise operation command may be executed is referred to as a selection area  32 , and the selection area  32  occupies some of the entire area of the display  30 . In addition, the selection area  32  is selected by using fingers (or bars), and the length of holding time after selecting is adjusted, thereby executing the stepwise operation command. 
     In this case, the selection means that the fingers (or bars) are used to touch the display  30 . In addition, since the input device  28  is substantially provided on the display  30 , touching the display  30  means touching the input device  28 . Naturally, the method of contact may not necessarily be used depending on the type of the input device. 
     Meanwhile, in the present disclosure, as long as a method is able to determine a step, various methods other than the methods using the movement distance and the length of holding time may be used. 
     That is, after tapping on the display  30  or tapping in a selection area, the step may be divided by the number of the tapping, or the step may be divided by the shapes of finger images after defining the finger images. 
     Exemplary Embodiment of Step Movement by Time 
     1) A step is determined by a value of holding time. 
     For example, when the holding time is maintained for 0.5 seconds, a step is moved by one step, when the holding time is maintained for one second, the step is moved by two steps, and when the holding time is maintained for 1.5 seconds, the step is moved by two steps. 
     2) The value of holding time becomes a boundary value of step movement. 
     For example, when the holding time is maintained for less than or equal to 0.5 seconds, the step is moved by one step, and when the holding time is maintained for greater than or equal to 0.5 seconds, the step is moved by two steps. When the holding time is maintained for less than or equal to one second, the step is moved by two steps, and when the holding time is maintained for greater than or equal to one second, the step is moved by three steps. 
     That is, when the holding time is maintained for less than or equal to a predetermined time T value, the step is moved by J steps, and when the holding time is maintained for greater than or equal to the predetermined time T value, the step is moved by J+1 steps. Alternately, when the holding time is maintained for less than or equal to a predetermined time T 1  value, the step is moved by J steps, and when the holding time is maintained for greater than or equal to the predetermined time T 1  value and less than or equal to a predetermined time T 2  value, the step is moved by J+1 steps. (Where J is a value greater than or equal to one and less than or equal to K−1, and K is a value of the highest level). 
     Exemplary Embodiment of Step Movement by Pressure 
     A function for recognizing the intensity of pressure may be further added to the input devices  28 - 1  and  28 - 2  of the present disclosure. The input device capable of recognizing pressure follows a conventional method. 
     In the case of the input devices  28 - 1  and  28 - 2  to which the pressure function is added, it is possible to execute a stepwise operation command as follows. 
     1) A step is divided according to the intensity of pressure, such as Step  1  pressure, Step  2  pressure, Step  3  pressure, Step K pressure, or the like. 
     2) Within the Step  1  pressure, the step is further divided by time. That is, the step is divided by the time, such as Step  1  time, Step  2  time, Step  3  time, Step K time, or the like. 
     3) The number of cases in the step are as follows. 
     Within the Step  1  pressure, there are Step  1  time, Step  2  time, Step  3  time, or Step K time. 
     Within the Step  2  pressure, there are Step  1  time, Step  2  time, Step  3  time, or Step K time. 
     Within the Step  3  pressure, there are Step  1  time, Step  2  time, Step  3  time, or Step K time. 
     Within the Step K pressure, there are Step  1  time, Step  2  time, Step  3  time, or Step K time. 
       FIG. 7  is a view illustrating an exemplary embodiment for describing the stepwise operation command. 
     Two points are determined by using two fingers (or two bars) and a movement distance traveled by each point is classified by each step, so that the operation command that enables a command to be recognized according to each step is referred to as the “stepwise operation command”. In addition, when the stepwise operation command is executed, a piece of information corresponding to each step is displayed on a screen of a display  30  of a smartphone. The step has a finite number N of at least two steps or more. Too many steps are not preferable, so 10 or five steps or fewer are appropriate. 
     In addition, to summarize the steps, description is as follows. 
     1) Steps are determined as Step  1 , Step  2 , Step  3 , and Step N, and a distance or holding time, which are recognized as a single step, is predetermined. Alternatively, a pressure value corresponding to one step applied to a selected point is predetermined. 
     2) The maximum number of recognizable steps is predetermined. The maximum recognizable distance (or time, or pressure) is also predetermined. 
     3) A stepwise operation command has a positive (+) direction and, in some cases, has a negative (−) direction as well. 
     4) When the stepwise operation command is executed, an error range is present. 
     5) For each step, a piece of information corresponding to each step is present. 
     Referring to  FIG. 7 , guiding lines  50  and  51 , which are movement paths between two points, are indicated. As shown in  FIG. 7(A) , the respective steps  50   a,    50   b,    50   c,    50   d,  and  50   e  are indicated on the guiding line. (In  FIG. 7(B) , the steps are respectively  51   a,    51   b,    51   c,    51   d,  and  51   e ). 
     Here, in the case of  FIG. 7(A)  in which a distance between the two selected points become closer to each other, 
     Step  1  is  50   a,  Step  2  is  50   b,  Step  3  is  50   c,  Step  4  is  50   d,  and Step  5  is  50   e.    
     In addition, in the case of  FIG. 7(B)  in which the distance between the two selected points increases, 
     Step  1  is  51   a,  Step  2  is  51   b,  Step  3  is  51   c,  Step  4  is  51   d,  and Step  5  is  51   e.    
     In addition, when a distance for moving one step is preset to 10 mm, in a case where a point is moved 20 mm by a stepwise operation command, two steps of movement is made. Since the whole step exists up to Step  5 , the maximal movement distance becomes 50 mm. 
     Naturally, the distance is not necessarily the same for each step. For example, it is possible that the distance from Step  1  to Step  2  may be set to 10 mm and the distance from Step  2  to Step  3  may be set to 12 mm. The distance for each step is predetermined. 
     In addition, when a program is executed by determining an algorithm, the distance for each step may also be variably changed. For example, although a movement distance from Step  1  to Step  2  is 10 mm, the movement distance between the steps may be manually or automatically changed to 12 mm before the stepwise operation command is executed. 
     In addition, when two points selected by the input device become closer to each other, negative (minus, −) movement is made, whereas when the two points become far away from each other, positive (plus, +) movement is made. (Conversely, when the two points become closer to each other, the positive (+) movement may be determined, whereas when the two points become far away from each other, the negative (−) movement may be determined). 
     In addition, when a program is executed by determining an algorithm, the distance for each step may also be variably changed. For example, although a movement distance from Step  1  to Step  2  is 10 mm, the movement distance between the steps may be manually or automatically changed to 12 mm before the stepwise operation command is executed. 
     In addition, when two points selected by the input device become closer to each other, negative (minus, −) movement is made, whereas when the two points become far away from each other, positive (plus, +) movement is made. (Conversely, when the two points become closer to each other, the positive (+) movement may be determined, whereas when the two points become far away from each other, the negative (−) movement may be determined). 
     In addition, in the present disclosure, when it is desired to execute a stepwise operation command, guiding lines  50  and  51 , on which scales for respective steps are indicated, may be allowed to be displayed on the screen of the display  30 , as shown in the exemplary embodiment of  FIG. 6 . 
     In the present disclosure, the “guiding lines  50  and  52 ” is one method by which each step and a distance and direction of each step are displayed on the display screen, so as to allow the stepwise operation command to be conveniently executed. Naturally, the guiding lines  50  and  52  are not necessarily displayed on the screen. 
     As such guiding lines are displayed, it is possible to visually provide information about the movement distance for each step. That is, the points are respectively moved distances corresponding to the scales indicated on the guiding lines  51  and  52 , thereby enabling a desired stepwise operation command to be executed. 
     In  FIG. 7 , the corresponding pieces of information for each step are “ 50   a - 1 ,  50   b - 1 ,  50   c - 1 ,  50   d - 1 , and  50   e - 1 ” and “ 51   a - 1 ,  51   b - 1 ,  51   c - 1 ,  51   d - 1 , and  51   e - 1 ”. 
     That is, in  FIG. 7(A) , information corresponding to Step  1  “ 50   a ” is “ 50   a - 1 ”, and in  FIG. 7(B) , information corresponding to Step  1  “ 51   a ” is “ 51   a - 1 ”. 
     In addition, the exemplary embodiments described above in clauses 1) to 5) may be applied as it is to examples of dividing the steps by the length of holding time (or pressure) as well. 
       FIG. 8  is a view illustrating yet another exemplary embodiment of an operation command through the input device. 
       FIG. 8(A)  is a view illustrating an exemplary embodiment in which one point selected by a finger or a bar through the input device is moved, and  FIG. 8(B)  is a view illustrating an exemplary embodiment describing an angle that is moved by a rotational motion. In addition, a command in a positive (+) step may be determined when a point moves upward or rotates counterclockwise, and a negative (−) direction may be determined opposite to the direction set to be positive (+) direction. 
     Meanwhile, as yet another exemplary embodiment of the present disclosure, each step may be determined by determining an upward and downward direction and a leftward and rightward direction. That is, the steps may be determined in such a way that an upward movement is Step  1 , a rightward movement is Step  2 , and a downward movement is Step  3 . In addition, such directions may be further subdivided into several directions. That is, starting in a clockwise direction, the entire direction may also be divided into nine steps by dividing the angle of the entire direction by 40 degrees. For example, when a point is moved clockwise at an angle of 80 degrees, the point is moved by two steps, thereby becoming Step  2 . 
     The movement of the step according to the stepwise operation command may be centered on a selection area  32  or a single point, and may be executed on the entire screen without particularly determining the selection area. 
       FIGS. 9 and 10  are views illustrating an exemplary embodiment in which each summary corresponding to each step is displayed in the stepwise operation command. 
       FIG. 9  is a view illustrating an example of a stepwise operation command in which a straight line distance is present, the straight line distance is divided into steps, and each summary content corresponding to each step is displayed. 
       FIG. 9  is a view illustrating that a movement distance (i.e., upward movement is positive (+) movement, and downward movement is negative (−) movement) is divided into steps, and then characteristics of information (i.e., content of information) in each step may be displayed on the screen. For example, Step  1  is “ 52   a ”, and Step  2  is “ 52   b ”. In addition, Step  1  summary information is “ 52   a - 1 ” and Step  2  summary information is “ 52   b - 1 ”. Accordingly, on the screen of the display  30 , the numerals indicating respective steps and the content of pieces of summary information corresponding to the respective steps may be displayed. 
     That is, in the exemplary embodiment of  FIG. 9 , numerals indicating steps are displayed on a guiding line  50 , and pieces of summary information corresponding to the respective steps are displayed. For example, the summary information corresponding to Step  1   52   a  is “Brief mobile phone specification”, and the summary information corresponding to Step  2   52   b  is “Detailed mobile phone specification”. Therefore, when Step  2  is selected, information for the detailed mobile phone specification is displayed on the screen of the display. 
     Data about the design of a guiding line and summary information displayed on the guiding line according to the exemplary embodiment of  FIG. 9  may be stored in the memory part  21  of the smartphone  110  and may also be stored in the database  104  of the server  100 . 
     In addition, when a stepwise operation command is selected (i.e., user&#39;s selection), the central processing unit  20  of the smartphone displays information on a guiding line and summary information, which are stored in the memory part  21 , on the display  30  on the basis of a selection signal of the stepwise operation command. 
     Meanwhile, when the selection signal for the stepwise operation command is transmitted to the server under the control of the central processing unit  20 , the controller  101  of the server searches the database  104  for the guiding line information and summary information, which are stored in the database, and transmits the retrieved information to the smartphone. In addition, the central processing unit  30  of the smartphone  110  displays the received information on the display  30 . In addition,  FIG. 10  is a view illustrating that a moved angle may be divided into steps, and the respective steps and the characteristics of information (i.e., summary information) for the respective steps may be displayed on the screen. 
     That is, on the guiding line  50 , steps  53   a,    53   b,    54   c,    54   d,  and  54   e  are displayed and summary information  53   a - 1 ,  53   b - 1 ,  54   c - 1 ,  54   d - 1 , and  54   e - 1  are also displayed. 
     —Method of Displaying Information Corresponding to Step on Display— 
     The execution process according to the exemplary embodiment of the stepwise operation command in the present disclosure is as follows: 
     1) When a point is selected (i.e., a finger or bar may be used to select the point) through the input device  28  of the smartphone, the input device driving part  27  outputs a position value (i.e., coordinates) of the selected point. In addition, when the point is moved, the input device driving part  27  outputs a movement value (i.e., coordinates) of the point. In this case, each value (i.e., coordinates) may be a number or a symbol. 
     2) The central processing unit  20  determines the output position and the movement value (i.e., coordinates) of the point, determines a movement step by using a designated algorithm, and determines a selected final step. 
     For example, when a current step is Step  2  and a point is moved in the positive (+) direction by two steps, the selected final step becomes Step  4 . 
     3) When the selected final step is determined, the central processing unit  20  selects information corresponding to the final step from the memory part  21  (or  21   a,    21   b,  or  21   c ), and displays the selected information on the display  30 . That is, the central processing unit outputs a driving signal that enables the selected information to be displayed on the display. 
     In this case, the final step is transmitted to the server  100 , and the controller  101  of the server may search the database  104  for the information corresponding to the final step and transmit the retrieved information to the smartphone. Then, the smartphone displays, on the screen of the display, the information that is received from the server and corresponding to the final step. 
     That is, when the final step is Step  3 , the central processing unit  20  of the smartphone  110  displays the information stored in Step  3  on the display  30 , the information being stored in the memory part  21  of the smartphone or the database  104  of the server. 
     In addition, the degree to which the smartphone itself is shifted or moved may also be divided into steps. 
     Meanwhile, the movement on an upper end of the display is allowed to be recognized by an image element, and a signal output from the image element is determined by using an algorithm, so that the degree of movement may be divided into steps. In this case, the shape of a finger, the shape of an eye, or the shape of another image may be used to divide and determine the steps. 
     That is, like the stepwise operation command, when the steps may be distinguished, divided, and selected, by using any input method on the smartphone, the information corresponding to the final step after executing the stepwise operation command may be displayed on the screen of the display. 
     —Information Stored in Database of Server and Memory Part of Smartphone— 
     1) Database information of the server is displayed on the display. 
     The smartphone  110  may be connected to the server via the wired/wireless Internet or a communication network so that a stepwise operation command may be executed. That is, when the stepwise operation command is input through the input device  28  of the smartphone  110 , the input information is transferred to the server through the communication network, the server selects information corresponding to the stepwise operation command from the database to transmit the selected information to the smartphone, and the smartphone may display the received new information on the screen of the display  30 . 
     2) Memory information of the smartphone is displayed on the display. 
     In addition, the information corresponding to the stepwise operation command may be displayed on the screen of the display by using the central processing unit  20  and the memory part  21  of the smartphone. 
     Meanwhile, at that time, the smartphone may receive the information on the steps from the server. This case may have the following order. 
     First, when a program capable of executing a stepwise operation command is executed, or a step capable of executing the stepwise operation command is displayed on the display, the central processing unit of the smartphone transmits, to the server, the execution of the program capable of executing the stepwise operation command. 
     When the program capable of executing the stepwise operation command is executed, the Step  1  information is normally displayed on the display, but depending on the termination status of the previous program, the Step  1  information is not necessarily displayed on the display. 
     Second, the controller of the server retrieves information corresponding to the steps from the database and transmits the information to the smartphone. 
     In this case, information on all steps may be transmitted from the server to the smartphone, but only information on some steps among the whole step may be transmitted from the server to the smartphone. 
     For example, when Steps  1  to  7  exist, the server may transmit all of the information on Steps  1  to  7  to the smartphone, but the server may transmit only some information on Steps  1  to  7  to the smartphone. 
     When only some steps are transmitted, the step information of adjacent steps currently displayed on the display is transmitted from the server to the smartphone. 
     Third, the central processing unit  20  of the smartphone stores the received information in the memory part  21 . 
     Fourth, when the final step is determined as a result of executing the stepwise operation command, information corresponding to the final step is selected from the information that is received from the server and stored in the memory part, and then the selected information is displayed on the display. 
     3) Mixed use 
     When information on the step corresponding to a time at which the stepwise operation command is started is displayed on the display, or when the final step is determined as a result of the stepwise operation command and the corresponding information is displayed on the display, the information displayed on the display may be information stored in the memory part  21  or information stored in the database  104  of the server. 
     That is, the information stored in the memory part  21  may be displayed on the display  30  for the Step  1  information, and the information stored in the database  104  may be displayed on the display  30  for the Step  2  information. 
     In addition, it is apparent that connection to the server or execution of an algorithm in the smartphone itself may be determined at each time depending on the type of each corresponding program and information. In addition, such determination may be performed by means of a program or by the selection of a user. 
     Further, it is apparent that in order to display the information corresponding to the steps of the stepwise operation command on the screen of the display, pieces of information corresponding to the respective steps should be classified and stored for each step in the database of the server or the memory part of the smartphone. 
       FIGS. 11 to 13  are views illustrating an exemplary embodiment in which a selection area exists in a text message service. 
     That is, the selection area  32  is present in a text message service, and a stepwise operation command may be executed for the selection area  32 . 
     Referring to  FIG. 11 , the selection area  32  is positioned on the sides of boxes of text  1  and  2 . That is, the selection area  32  is positioned on the side of the box of received text  1 , or on the side of the box of transmitted text  2 . 
     In addition, the selection area  32  is present in an area between transmitted/received text, or the selection area may be separated from the transmitted/received text as well, but the selection area  32  may also be attached to the transmitted/received text. 
       FIG. 12  is an exemplary embodiment in which the selection area  32  is present between the transmitted text  1  and the received text  2 . 
       FIG. 13  is a view illustrating an exemplary embodiment in which the boxes of transmitted/received text  1  and  2  and the selection area  32  are attached to each other. 
     In this case, the method in which the boxes of the transmitted/received text  1  and  2  and the selection area  32  are attached to each other may vary depending on the shape or design method of the selection area  32 . 
     As a result,  FIGS. 11 to 13  illustrate the exemplary embodiment in which the selection area  32  may be present in the area generated between the transmitted/received text  1  and  2 , or the transmitted text or received text and the selection area may be attached to each other. 
     In addition, in the display  30 , two or more selection areas existing between the transmitted/received text  1  and  2  are applicable as well. 
     —Characteristics of Information and Selection Area Existing Between Transmitted/Received Text— 
     First, the types of Step  1  information while being a selection area are as follows: 
     1) When transmitted/received text  1  and  2  are displayed, the information displayed between the transmitted/received text is the Step  1  information. 
     2) A stepwise operation command may be executed for the Step  1  information displayed between the transmitted/received text. 
     In this case, there may exist a selection area where the stepwise operation command may be separately executed. 
     3) The Step  1  information is information in which a box exists and text or an image is displayed in the box. 
     4) The Step  1  information is information in which a box does not exist, but only text or an image is present. 
     5) The Step  1  information is information that exists as a video. In this case, the video may or may not exist in the box. 
     6) The box does not necessarily mean a rectangle. Depending on the type of information or the design, various forms such as a shape of a circle are possible. 
     Second, characteristics of information on Step  2  or higher are as follows: 
     1) The information on Step  2  or higher is information displayed on the display as a result of executing a stepwise operation command on the Step  1  information. 
     2) From Step  2  or higher, a selection area may or may not be the selection area in which the stepwise operation command may be executed. 
     In addition, when there may be provided a selection area in which the stepwise operation command may be executed, the selection area in which the stepwise operation command may be separately executed may exist 
     3) The information on Step  2  or higher is not necessarily displayed between the transmitted/received text  1  and  2 . 
     The information on Step  2  or higher may be displayed between the transmitted/received text  1  and  2 , but may be displayed by being overlapped with the transmitted/received text  1  and  2 . 
     While a menu is displayed at the upper end of the display, the information on Step  2  or higher may be displayed on the entire screen of the display. 
     While the menu is displayed at the upper end of the display, the information on Step  2  or higher may be displayed on a partial area of the screen of the display. 
     4) The information is displayed as text, image, or video. 
       FIG. 14  is a view illustrating an exemplary embodiment of information displayed for each step. 
       FIG. 14 ( 1 ) is a form of an image as a form of the Step  1  information. Naturally, the information is not necessarily limited to image information. The general characteristics of the Step  1  information are in accordance with the clauses described in the “Characteristics of Information and Selection Area Existing Between Transmitted/received Text” described above. 
     In addition,  FIGS. 14 ( 2 ) to  14 ( 7 ) illustrate the form of information on Step  2  or higher. In addition, the form and characteristics of the information on Step  2  or higher are in accordance with the clauses described in “Characteristics of Information and Selection Area Existing Between Transmitted/received Text” described above. 
     In this case,  FIG. 14 ( 3 ) is text information on the appearance of a design shape. 
     In addition, in  FIG. 14 ( 4 ), information on steps is displayed as at least two or more table of contents  71 . In addition, when one of the table of contents  71  is selected, additional information about the selected table of contents  71  may be displayed on the display. 
     Meanwhile,  FIG. 14 ( 5 ) is information that may be linked to other functions,  FIG. 14 ( 6 ) is information that may be linked to other programs, and  FIG. 14 ( 7 ) is information that may be linked to knowledge information. 
     In addition, when the information corresponding to the exemplary embodiment of the above example is displayed on the display  30 , audio information (or voice information) may also be output together. The audio information is output through a speaker provided in the smartphone  110 . 
     Exemplary Embodiment of Information Displayed for Each Step According to FIG.  14   
     Step  1 : Image information is displayed on the display  30 . It is possible to execute a stepwise operation command. 
     Step  2 : The video or text information is displayed on the display  30 . It may or may not be possible to execute the stepwise operation command. 
     Step  3 : The video or text information is displayed on the display  30 . It may or may not be possible to execute the stepwise operation command. 
     Step  4 : One of items of “other functions”, “other programs”, or “knowledge information” is selected and displayed on the display  30 . It may or may not be possible to execute the stepwise operation command. 
       FIGS. 15 to 17  are views illustrating the exemplary embodiment of information displayed on the display in each step. 
       FIG. 15  is a view illustrating an exemplary embodiment in which names of other functions are displayed as a table of contents and displayed as information on arbitrary steps. In addition, when one item is selected from the table of contents of  FIG. 15 , the selected other functions are executed. 
     In this case, other functions refer to as different functions provided within the text service. In the meantime, the text service provides a phone function (i.e., Voice Talk), provides news information or shopping information, and also provides a setting function, so as to enable the text service environment to be changed. Naturally, a friend list is also provided. That is, other functions in the exemplary embodiment of  FIG. 15  refer to as various functions provided within the text service. 
       FIG. 15(A)  illustrates information  70  in which the names of other functions are displayed in the form of a table of contents. That is, the information  70  on the other functions is provided in the form of the table of contents  71 . For example, when Voice Talk is selected from the table of contents of  FIG. 15(A) , a link is established so that Voice Talk (i.e., phone) is usable. That is, it is possible to follow a procedure for executing Voice Talk that is a function provided by the text message service. 
     Naturally, in the table of contents of  FIG. 15(A) , it is possible to follow the procedure in which when a friend list is selected, the friend list is displayed, when a text list is selected, the text list is displayed, and when text (not shown in the exemplary embodiment of  FIG. 15(A) ) is selected, transmission of the text is possible(in the text message service). 
     —Display Reflecting Priority in Table of Contents— 
     In this case, a priority may be determined. That is, in various functions provided by the text message service capable of executing the stepwise operation command of the present disclosure, the priority of functions among the functions frequently used by a user who uses the text message service may be determined. 
     For example, when the Voice talk is used the most frequently, a first priority is Voice talk, and when the friend list display is used the second most frequently, a second priority is the friend list display, and when the text list display is used the third most frequently, a third priority is the text list display. 
     Then, as shown in  FIG. 15(A) , when displayed in the form of the table of contents, the names of functions corresponding to the first, second, and third priorities described above (for example, Voice Talk, friend list, or text list, etc.) are displayed in the table of contents. Naturally, in some cases, fourth, fifth, and higher priorities may also be displayed. In addition, when one of the table of contents indicating the names of the functions is selected, the selected function is executed. For example, when a voice talk function is selected from the table of contents of  FIG. 15(A) , the voice talk function may be performed, and when the friend list is selected, the friend list is displayed on the display  30 . 
       FIG. 15(B)  is a view illustrating an exemplary embodiment in which only one of other functions  74  is displayed. In this case, when the one of other functions is selected, the selected function is executed. In this case, one function having a higher priority may be displayed as the one of other functions  74 . 
       FIG. 16  is a view illustrating an exemplary embodiment in which names of other programs are displayed as a table of contents, which are information on arbitrary steps. In addition, when one item is selected from the table of contents of  FIG. 16 , the selected other program is executed. 
     In this case, the other programs mean other programs or applications provided within the smartphone  110 . In the meantime, even within the smartphone  110 , various programs are performed in the form of applications in addition to the programs originally provided in the smartphone  110 . 
     For example, in addition to programs such as text messages, phone calls, text lists, and the Internet, which are originally provided in the smartphone, various programs such as games, portal sites, maps, shopping, and the like are provided through applications, and it may be seen that  FIG. 16  illustrates the meaning in which these programs are displayed as the table of contents. 
       FIG. 16  is a view illustrating information  90  in which the names of other programs are displayed in the form of a table of contents. For example, when the phone is selected from the table of contents of  FIG. 16 , a link is established so as to allow a phone call to be usable. In this case, the phone function is not a voice communication function (i.e., Voice Talk) provided within the text message service (i.e., application program) according to the present disclosure, but a phone program provided by the smartphone itself through a communication service provider. 
     In addition, when the text is selected from the table of contents of  FIG. 16 , a link is established so that the text message service is usable. In this case, the text message function is not a text message service provided within the text message service (i.e., application program) of the present disclosure, but a text message delivery program provided by the smartphone itself through the communication service provider. 
     That is, it is possible to follow a procedure in which the program provided in the smartphone may be executed. 
     Naturally, when the camera is selected from the table of contents of  FIG. 16 , a link is established so as to execute a camera program, and when the map is selected, a link is established so as to execute a map program that is an application. 
     —Display Reflecting Priority in Table of Contents— 
     In this case, a priority may be determined. That is, in various programs (i.e., applications and programs provided by the smartphone are included, and all functions are included when not provided within the text message service of the present disclosure. In other words, the programs are provided separately from the text message service of the present disclosure) provided in a smartphone capable of executing the stepwise operation command of the present disclosure, priorities may be determined among the programs frequently used by a user who uses the programs. 
     For example, when a phone program of a communication service provider is the most frequently used, the first priority is the phone program of the communication service provider, and when a text message program of the communication service provider is second most frequently used, the second priority is the text message program of the communication service provider, and when an Internet program of the communication service provider is third most frequently used, the third priority is the Internet program of the communication service provider. 
     Then, as in the example of  FIG. 16 , when displayed in the form of the table of contents, the names of functions respectively corresponding to the first, second, and third priorities (e.g., phone, text message, Internet, or the like) are displayed in the table of contents. 
     Naturally, in some cases, fourth, fifth, and higher priorities may also be displayed. In addition, when one of the table of contents indicating the names of the functions is selected, the selected function is executed. For example, in the table of contents of  FIG. 16 , when the phone is selected, the phone program may be executed, and when the text message is selected, the text message program may be executed. 
     Meanwhile, the time of use may also be included in the priority. In other words, the frequency of use and the time of use are reflected in the priority. For example, although the frequency of use is small, when once used with a lot of time, the priority may become higher. 
     However, determining of how many weights should be applied to each of the frequency of use and the time of use may vary depending on an algorithm of the program. 
     —Recommended Table of Contents— 
     Items existing in the table of contents  70 ,  80 , and  90  may be generated by a predetermined algorithm. For example, “user&#39;s search word” and “user&#39;s input word” may be analyzed to generate the items in the table of contents. In addition, the items in the table of contents may be generated by the recommendation of an operator who operates the content of the present disclosure. 
     That is, when there are six total items in the table of contents, four items thereof are generated by reflecting priorities by time or frequency, and the remaining two items thereof may be generated by the algorithm determined above or at the operator&#39;s recommendation. 
     —Number of Items in Table of Contents— 
     The number of items in the table of contents does not necessarily have to be plural. When there is more than one item, the embodiment of the present disclosure may be performed. 
       FIG. 17  is a view illustrating information of an exemplary embodiment describing knowledge information. 
     In the present disclosure, the knowledge information  90  is referred to as knowledge information related to news, weather, stories, shopping, sports, and the like. 
     In addition, the exemplary embodiment shown in  FIG. 17  is also in accordance with the exemplary embodiments shown in  FIGS. 15 and 16 . That is, the knowledge information  90  is displayed as a table of contents  91 , and when one item is selected from the table of contents  91 , information corresponding to the selected table of contents  91  is displayed on the display  30 . 
     In addition, in the knowledge information  90 , a method of priority in which the tables of contents are displayed is also in accordance with the exemplary embodiments of  FIGS. 15 and 16 . 
     —Selection and Execution of Table of Contents— 
     The process of selection and execution of the table of contents in  FIGS. 15 to 17  is as follows. 
     1) A selection area is selected through the input device  28  and a stepwise operation command is executed. 
     2) The central processing unit  20  determines a movement step determined according to the result of execution of the stepwise operation command, and determines the final step. 
     In this case, the final step is a step reflected by adding or subtracting the movement step from the initial step. (refer to the previous exemplary embodiment of the present disclosure) 
     3) The central processing unit  20  selects the information corresponding to the final step from the memory part  21 , or receives the information from the server, thereby displaying the information on the display  30 . 
     In this case, the central processing unit  20  transmits a value of the final step through the R/F part  24  and the communication network, and the controller  101  of the server selects the information corresponding to the final step from the database  104  and transmits the information to the smartphone  110 . 
     Naturally, the central processing unit of the smartphone  110  may receive the information corresponding to each step in advance from the server and store the information in the memory part  21 . 
     4) When the information corresponding to the final step is a table of contents, the central processing unit  20  displays the information corresponding to the final step on the display  30  in the form of the table of contents. 
     5) When one item is selected from the table of contents through the input device  28 , the central processing unit  20  may display the knowledge information about the selected table of contents on the display  30 , execute the program for the selected table of contents, or perform other functions for the selected table of contents. 
     In this case, the central processing unit  20  may proceed with the result for the selected table of contents through the algorithm or the information stored in the memory part  21 , and may also receive the information from the server or is connected to the server, thereby processing the result for the selected table of contents. 
     —Group Item Representing One Item and One Group Item— 
     In  FIGS. 15, 16, and 17 , there are group items  72 ,  82 , and  92 . In addition, when the group item is selected, another table of contents is generated. 
     That is, in the exemplary embodiments of  FIGS. 15, 16, and 17 , when an item in the table of contents is selected, other functions or programs corresponding to the selected item are executed, or the knowledge information is displayed. However, when the group item  72 ,  82 , and  92  is selected, another table of contents is displayed. 
     Accordingly, when the information corresponding to the step is displayed on the display  30 , an item and a group item may be displayed together. 
     Meanwhile, the exemplary embodiments of the group items  72 ,  82 , and  92  are as follows: 
     1) There are cases where the group items, such as a group item  72  marked with “#” and group items  82  and  92  marked with “•”, are not indicated as words but are indicated as symbols, and when the group items  72 ,  82 , and  92  are selected, a separate window  97  (i.e., a window displayed in the form of a box on the display) is generated and information in the form of the table of contents is displayed in the separate window. 
     For example, when the group item  72  marked with “#” is selected, items such as “Friend Search”, “Notification”, “Remittance”, “Security”, and “Version Information” may be displayed as the table of contents in a separate window. 
     2) Words may be displayed in the group items  72 ,  82 , and  92 . For example, when a word “Game” is displayed in the group item  82  representing the program, and when an item marked as “Game” is selected, game items such as “StarCraft”, “Diablo”, “Tetris”, and the like may be displayed as the table of contents in a separate window. 
     That is, in a case where the words of a category concept is displayed as group items  72 ,  82 , and  92 , when the group items  72 ,  82 , and  92  are selected, the items respectively corresponding to the words are displayed as the table of contents in the separate window. 
     In this case, it may be said that the concept of a hierarchical structure of words is used. 
     3) When the group table of contents  72  marked with “#” and the group items  82  and  92  marked with “•” are selected, a low priority table of contents may be displayed in a separate window. 
     For example, in the examples of  FIGS. 15, 16, and 17 , when items displayed in the table of contents have high priorities, the items displayed in the table of contents displayed in the separate window are items of low priorities. 
     Meanwhile, in  FIGS. 15, 16, and 17 , it has been described that the table of contents is displayed separately for other functions, other programs, and knowledge information, but as the items in the same table of contents, it is not necessary that only other functions exist, only other programs exist, or only knowledge information exist. For example, other programs, other functions, or knowledge information may exist together as respective items in the same table of contents. 
       FIG. 18  is a view illustrating an exemplary embodiment in which a group item is selected. 
     When there are group items  72 ,  82 , and  92  within the table of contents  70 ,  80 , and  90 , respectively, and when one of the group items  72 ,  82 , and  92  is selected, the selected items  72   a,    82   a,  and  92   a  are displayed separately from the unselected group items  72 ,  82 , and  92 . That is, the group items are distinguished by color, thickness of a line, brightness, and the like, or are displayed to be visually distinguished by flickering. 
     In addition, as for additional information on the selected items  72   a,    82   a,  and  92   a,  new items  97   a  are displayed as a table of contents in a separate window  97 . 
     —Display of Separate Window— 
     1) There are items and group items in the table of contents. 
     The table of contents may be composed only of items, or the table of contents may be composed of only group items. In addition, both items and group items may exist in the table of contents together. 
     2) When any item  71 ,  81 , or  91  in the table of contents  70 ,  80 , and  90  is selected, information on the selected item is displayed in the separate window  97 . The exemplary embodiment of  FIG. 18  describes a case in which group items  72 ,  82 , and  92  are selected in the table of contents, but the exemplary embodiment of  FIG. 18  is also applied to a case where items  71 ,  81 , and  91  are selected in the table of contents  70 ,  80 ,  90 . 
     Meanwhile, when an item or a group item is selected, the corresponding information may be displayed in the separate window  97 , but it is possible that the corresponding information is displayed on the entire screen of the display. However, even when the corresponding information is displayed on the entire screen of the display, the selection menu, control menu, and the like are displayed together. (Here, menu refers to the commonly used menu displayed at the upper end of the screen or a part of the screen). 
     3) The order of displaying the separate window is as follows: 
     One item  71 ,  81 , and  91 , or one group item  72 ,  82 , and  92  is selected from among the table of contents  70 ,  80 , and  90  through the input device  28 . 
     The input device outputs the selected position value to the central processing unit, and the central processing unit determines which item  71 ,  81 , and  91  or which group item  72 ,  82 , and  92  is selected. 
     The central processing unit  20  displays information corresponding to the selected item or group item on the display. 
     The information corresponding to the selected item or group item may be stored in the memory part  21 . Alternately, the information corresponding to the selected item or group item may be the information transmitted from a server. 
     When information is the information stored in the memory part, the central processing unit selects the information corresponding to the selected item or group item from the memory part and displays the selected information on the display. 
     When information is the information to be received from the server, the central processing unit  20  transmits the status (i.e., a specified code may be used) of the selected item or group item to the server, and the controller  101  of the server selects the information corresponding to the selected item or group item from the database  104  and transmits the selected information to the smartphone through the communication network. Then, the central processing unit  20  of the smartphone displays the information received from the server on the display. 
     Meanwhile, in the present disclosure, items and group items are distinguished from each other in the table of contents, and are described as examples for expression of description, but in an actual exemplary embodiment, the items and group items are not used separately. 
       FIGS. 19 to 21  are views illustrating an exemplary embodiment for describing a concept of a hierarchical structure. 
       FIG. 19  is a view illustrating an exemplary embodiment of the hierarchical structure.  FIG. 19  is the view illustrating the exemplary embodiment, assuming that “Shopping” is selected in the table of contents of  FIG. 17 . When the “Shopping” is selected in the table of contents of  FIG. 17 , items related to shopping are displayed in a separate window  97 . In addition, in the present disclosure, for convenience of description, the table of contents that is first displayed in the separate window is referred to as a first layer. 
     In the first layer  60 , items from No. 1 “Fashion Brand” to No. 9 “Household living products” exist. In addition, a second hierarchical structure is composed of nine tables of contents. In addition, the number of tables of contents in third hierarchical structure is present as much as the number of all items existing in the table of contents of the second hierarchy structure. 
     Meanwhile, in the above example, the description that the items are nine is for merely one exemplary embodiment, and it is possible that the number of items may be one or more. 
     That is, in the second hierarchical structure, the table of contents is a lower layer of the item “1. Fashion Brand” among the table of contents of the first layer  60 . In addition, in the second hierarchical structure, the table of contents  61 - 9  is a lower layer of the item “9. Household living products” among the table of contents of the first layer  60 . 
     In addition, in the third hierarchical structure, the table of contents  61 - 1 - 1  is a lower layer of the item “1-1. Women&#39;s clothing fashion” among the table of contents of the second layer  61 - 1 . In addition, in the third hierarchical structure, the table of contents  61 - 9 - 10  is a lower layer of the item “10. 000 0000 00” among the table of contents of the second layer  61 - 9 . 
     That is, when one item is selected from among the items in the table of contents of the first layer, information corresponding to the selected item appears in the table of contents, and this table of contents becomes the second layer, and other items exist in a table of contents of the second layer. 
     In addition, when one item is selected from among the items in the table of contents of the second layer, information corresponding to the selected item appears in the table of contents, and this table of contents becomes the third layer, and other items exist in a table of contents of the third layer. Accordingly, in this way, the fourth layer and the fifth layer may also exist. 
     For example, when the item “Newspaper” is selected, a new table of contents with items such as Newsweek, New York Times, and Washington Post is displayed. In addition, when the item “Internet” is selected, a new table of contents with items such as Google, Yahoo, and Naver is displayed. 
     In addition, when the item “Messenger” is selected, a new table of contents with items such as KakaoTalk, Telegram, Line, and WeChat is displayed, and when Telegram is selected from among the items, a link to Telegram is established. 
       FIG. 20  is a view illustrating an exemplary embodiment in which the first layer is displayed in a separate window  97  on the display  30 . In addition,  FIG. 21  is a view illustrating an exemplary embodiment in which the second layer is displayed in an additional separate window  97   a.    
     Consequently, the table of contents is determined by reflecting priorities, input words, recommendations, etc., but is also determined by the concept of the hierarchical structure. 
     —Stepwise Operation Command— 
     In the present disclosure, there are steps ranging from the lowest step, that is Step  1 , to the highest step, that is Step K. A stepwise operation command, which is a movement method from current Step N (i.e., Step N is any one step from Step  1  to Step K) to any step, will be described. In addition, in  FIGS. 5 to 10  of the present disclosure, various exemplary embodiments of the stepwise operation command have been described. 
     The stepwise operation command is a method capable of moving two or more steps from the current step by using the stepwise operation command. In addition, as moving from Step  1  to Step  3 , there is provided a stepwise operation command that enables current step to be moved in a higher step direction (i.e., Step K direction). In addition, as moving from Step  3  to Step  1 , there is provided a stepwise operation command that enables current step to be moved in a lower step direction (i.e., Step  1  direction). 
     In this case, when a stepwise operation command is executed by a method such as distance movement or angle movement, both movement in the higher step direction and movement in the lower step direction are possible. However, when a stepwise operation command is executed by a method of holding time (or a method of determining steps by the intensity of pressure), it is possible to move in the higher level direction, but it is not easy to move in the lower level direction. Therefore, the present disclosure is intended to present a more various stepwise operation commands. 
     1) Moving to a higher step executes a stepwise operation command by the method of holding time (or the method of applying pressure, but moving to a lower step performs a stepwise operation command by the method of the distance movement or angle movement. 
     Moving to the higher step is possible with the stepwise operation command by the method of the exemplary embodiment in  FIG. 6 , and moving to the lower step is possible with the stepwise operation command by the method shown in  FIG. 5 or 8 . 
     For example, when moving from Step  1  to Step  3 , the stepwise operation command is executed by the method of holding time of one second, and when moving from Step  3  to Step  1 , the stepwise operation command is executed by the method of movement by 2 cm or movement by 30 degrees. 
     2) In Step  1 , it is possible to move more than two steps, but after Step  2 , the stepwise operation command may not be executed. 
     Alternatively, only one step movement may be possible after Step  2 , or one step movement in the lower step direction (i.e., Step  1  direction) may be possible after Step  2 . 
     Naturally, when adjusting the method of the step that is moved by the stepwise operation command after Step  2 , the step for movement is not limited to two steps. From Step  3  or higher, a step movement rule of the clause 2) may be applied, and from any Step N, the step movement rule of the clause 2) may be applied. 
     Meanwhile, in any Step N, only J-step movement may be necessarily enabled, where N is from 2 or more to K, and J is 2 or more. The J-step movement may be performed either in the higher step direction or the lower step direction. 
     3) Moving to the higher step executes a stepwise operation command by the method of dividing the length of holding time into steps (or the method of dividing steps by the intensity of pressure), but a stepwise operation command is possible to be executed by selecting a specific mark (i.e., operation mark  34   a  in  FIG. 22 ) for the lower step. 
       FIG. 22  is a view illustrating an exemplary embodiment describing the method of the exemplary embodiment of the clause 2). 
       FIG. 22(A)  is a view illustrating Step  1  in which a stepwise operation command is executable, and corresponds to the selection area  32  in the previous exemplary embodiment of the present disclosure. In  FIG. 22(A) , Step  1  information is shown as an image, but it may be text information, video information, or the like. 
     The image (in Step  1 ) of  FIG. 22(A)  is selected through the input device  28 , and depending on the selected length of holding time,  FIG. 22(B) , which is Step  2  (reference numeral  34 ), may be displayed on the display  30 , and  FIG. 22(C) , which is Step  3 , may be displayed on the display  30 . 
     However, there are difficulties in using the method of dividing the length of holding time into steps (or method of dividing the steps by the intensity of pressure), in order to move from Step  3  to Step  1  or  2 , or to move from Step  2  to Step  1 . 
     That is, in the present disclosure, a method of the stepwise operation command for moving in the lower step direction (i.e., Step  1  direction) is provided in various exemplary embodiments below. 
     1) When touched once, a step moves only one step in the lower step direction (i.e., Step  1  direction). 
     2) When an exit button conventionally used on smartphones is selected, the step moves only one step in the lower step direction (i.e., Step  1  direction). 
     3) When an operation mark  34   a  in  FIG. 22  is selected, the step moves in the lower step direction (i.e., Step  1  direction). 
     That is, in  FIG. 22 , when Step  1  (reference numeral  32 ), Step  2  (reference numeral  34 ), or Step  3  (reference numeral  36 ) is selected and a stepwise operation command is executed, the step is moved in the higher step direction. 
     However, when the operation mark  34   a  is selected and the stepwise operation command is executed, the step is moved in the lower step direction. Moving to the lower step means moving from Step  3  to Step  1 . 
     Here, the fad that the steps  32 ,  34 , and  36 , or the operation mark  34   a  is selected means that a selection area where the steps  32 ,  34 , and  36 , or the operation mark  34   a  is displayed is selected on the display through the input device. 
       FIG. 23  is a view illustrating another exemplary embodiment of information that may be expressed as steps. 
     In  FIGS. 14 to 18 , various exemplary embodiments of information that may be displayed as steps have been described. In addition,  FIG. 24  illustrates yet another exemplary embodiment of information that may be displayed as steps. 
     Referring to the exemplary embodiment of  FIG. 23 , a search window  95  is displayed on the display  30  as information corresponding to an arbitrary Step N (where N is any N from 1 or more to K or less), a word search window  95   a  may exist within the search window  95 , and a voice search window  95   a  may exist. It is apparent that an image search window may additionally exist. 
     Meanwhile, through the search window, information may be searched for, other functions may be searched for, and other programs may be searched for. 
     In addition, when other functions are searched for and selected, the other functions are performed or linked. In addition, when other programs are searched for and selected, the other programs are performed or linked. 
       FIG. 24  is a view illustrating an exemplary embodiment in which text is a selection area. 
     As shown in  FIG. 24 , when the received text  1  and  32  are selected as selection areas, and when a stepwise operation command is executed for the received text  1  and  32 , which are selected, the information corresponding to Step  2  or Step  3  (reference numeral  34  or  36 ) is displayed on the display  30 . 
     In addition, according to the method for embodiment, information corresponding to Step  4 , Step  5 , or higher steps are also displayed on the display  30 . 
     Meanwhile, even when the transmitted/received text  1  and  2  respectively become selection areas and each stepwise operation command is executed, the method of the exemplary embodiment of the present disclosure is applied as it is. 
     For example, when the transmitted/received text  1  and  2  respectively become selection areas  32  and each stepwise operation command is executed for the transmitted/received text  1  and  2 , the information corresponding to Step  2 , Step  3 , or Step N is displayed on the display  30 . 
     Then, a search window as the information corresponding to an arbitrary Step N may be displayed on the display  30 . In addition, various searches such as keyword search, friend list search, and phone number search may be performed through the search window. 
     In this case, the keyword search may include: a search through the Internet network, a word search within text transmitted and received, a search for other functions, or a search for other programs within a smartphone. 
       FIG. 25  is an exemplary diagram in which a stepwise information provision method is applied to an emoticon service used in the text service. 
       FIG. 25(A)  is a view illustrating information provided by a service operator. That is, a selection window  40  is displayed, and selection items  41  exist in the selection window  40 . In addition, one item is selected from among the selection items  41 . That is, it may be said that the principle in use in the present disclosure is similar to selecting one emoticon image from among the emoticon images provided in a typical text message service. 
     In addition, when a step input  42  is selected in  FIG. 25(A) , an input window  45  is displayed as shown in  FIG. 25(B) . That is,  FIG. 25(B)  shows a new method that does not exist in the conventional emoticon service. 
     As shown in  FIG. 25(B) , the input window  45  includes: an input space  47  configured to input information, a step display  46  configured to display a step of input information, and an attachment mark  48  configured to attach other data (i.e., text, image, or video). Here, the step display  46  indicates what step information is the information currently input in the input space  47 . That is, when “Step  3 ” is displayed on the step display  46 , the information input to the input space  47  is Step  3  information. 
     In addition, although not shown in  FIG. 25(B) , it is natural that an input mark for inputting information and an additional step input mark for inputting an additional step may also exist. 
     In this case, when the input mark is selected, the information input in the input space  47  is stored. (The information may be stored in the memory part  21 , and may be transmitted to the server so as to be stored in the database  104  of the server). 
     In addition, when the additional step input mark is selected, the information of the next step may be allowed to be input. A new input window  45  is displayed and information of the new step may be input into the input window  45 . That is, when the information input to the current input window  45  is Step  3  (or Step N), the information input into the new input window  45  is Step  4  (or Step N+1). 
       FIG. 26  is a view illustrating the exemplary embodiment of  FIG. 25  and illustrates a case where the exemplary embodiment is applied to an emoticon. 
       FIG. 26 ( 1 ) is a view illustrating Step  1 , which is a selection area  32  and an image,  FIG. 26 ( 2 ) is a view illustrating Step  2  (reference numeral  34 ) information as a video,  FIG. 26 ( 3 ) is a view illustrating Step  3  (reference numeral  36 ) information, and  FIG. 26 ( 4 ) is a view illustrating Step  4  (reference numeral  38 ) information. (In this case, Step  1  and  2  information is not limited to images or videos. Text data or data in which text and an image are mixed are also possible, and data in which text and a video are mixed is also possible. In addition, the same is also true for the data constituting other step information). 
       FIG. 27  is a view illustrating an exemplary embodiment in which the present disclosure is applied to text retransmission. 
     Conventionally, it is possible to retransmit (or forward) the received text  1 . In this case, in the present disclosure, a step input function is further added. When “step input” is selected from a retransmission menu  2   b  of the exemplary embodiment of  FIG. 27 , an input window  45  for inputting information according to steps is displayed, and information about the steps is input. 
     In this case, the input window  45  may be displayed in a text input window  2   a,  which is an area where text is normally input when using a text service. 
       FIGS. 28 and 29  are views illustrating an exemplary embodiment describing a method for inputting information for each step. 
     As shown in  FIG. 28 , an input mark  2   c  is present in the text input window  2   a,  and the input mark  2   c  has no significant difference in function from the input mark used in general text content. Accordingly, the input mark  2   c  may be selected through the input device  28 . 
       FIG. 29  is a view illustrating an exemplary embodiment describing a method in which the input mark  2   c  is displayed on the display  30  when selected through the input device  28 . That is, as shown in  FIG. 29(A) , when the input mark  2   c  is selected, a selection window  2   d  is displayed in the text input window  2   a  or on the display  30 . In addition, in the selection window  2   d,  several items that are selectable are displayed as a table of contents. 
     In addition, a step input item  2   e  exists in the above various items, and other input item  2   f  also exist. Naturally, in  FIG. 29 , a description of the other input item  2   f  is omitted. 
     In this case, when the step input item  2   e  is selected through the input device  28 , the input window  45  is displayed on the display  30  as shown in  FIG. 29(B) . Then, information about the step is input through the input window  45 . 
     Meanwhile, the method of the exemplary embodiment of  FIG. 25  of the present disclosure is applied to the method of inputting information through the input window  45 . In the exemplary embodiment of  FIG. 25 , the information on some steps is simply provided by an operator, but in the exemplary embodiments of  FIGS. 28 and 29 , all information from Step  1  (i.e., the lowest step) to Step K (i.e., the highest step) is input through the smartphone  110 . That is, a user who uses the present disclosure inputs all information from Step  1  (i.e., the lowest step) to Step K (i.e., the highest step). 
     In addition, when all information on the steps is input, the input information is transmitted to the server or stored in the memory part  21 . 
     Meanwhile, being transmitted to the server may mean that the information of the input step is transmitted as text to the other smartphone that is connected, via the text service, to the smartphone of the present disclosure. Naturally, the information may be transmitted in a method for other content service other than the text service. 
       FIG. 30  is a view illustrating an exemplary embodiment for describing a block diagram when the other smartphone capable of inputting steps is connected to the server. 
       FIG. 30  is a view illustrating the other smartphone  110 - 1  in which the stepwise information provision method of the present disclosure is performed. In addition, it may be seen that the step input is input from the other smartphone  110 - 1 . In this case, the other smartphone  110 - 1  or portable terminal is substantially the same as or has the same characteristics as the smartphone  110  or portable terminal described in the present disclosure. Therefore, all exemplary embodiments of the present disclosure are also applied to the other smartphone  110 - 1 . 
     —Sequence for Step Input— 
     1) The step input is selected through the input device  28 - 1  of the other smartphone  110 - 1 . At this time, the other smartphones  110 - 1  may be two or more. 
     2) When the step input is selected, the central processing unit  20 - 1  of the other smartphone  110 - 1  displays the input window  45  on the display  30 . 
     3) When step information is input through the input device  28 - 1 , the central processing unit  20 - 1  of the other smartphone  110 - 1  transmits the step information about the input step to the server. 
     4) The controller of the server transmits the information on the input step to the smartphone  110  through the communication network. Meanwhile, the controller of the server may store the information on the above step in the database. 
     5) When the information display for the step is selected through the input device  28  in the smartphone  110  that has received the information about the step, the central processing unit  20  of the smartphone  110  displays the information about the step on the display  30 . 
     In this case, the exemplary embodiment described in the present disclosure is applied to the method of displaying the information about the step on the display. 
       FIG. 31  is a view illustrating an exemplary embodiment for describing still another exemplary embodiment of the present disclosure. 
       FIG. 31(A)  is a view illustrating an exemplary embodiment in which a password input window is displayed on the display  30 . For example, when a password is set for information about a certain step, only after entering the password, the information about the step is displayed on the display  30 . 
     That is, in a case where information of Step N, which is any one step in a range from Step  2 , Step  3 , and Step  4  (reference numerals are  34 ,  36 , and  38 ) or Step  1  (i.e., the lowest step) to Step K (i.e., the highest step), is displayed on the display  30 , and when a password is set in the information on Step N, the password input window  5  is displayed on the display  30  as shown in  FIG. 31(A) . 
     In addition, when the password is input in the password input window  5  and the input password matches the preset password, the central processing unit  20  or the controller  101  of the server displays the information about the step on the display  30 . A conventional method is used as the method in which the controller of the server determines whether the password matches or not and displays the information on the display. 
       FIG. 31(B)  is a view illustrating an exemplary embodiment describing a method in which step information is automatically displayed. 
     In the exemplary embodiment of the present disclosure, when a user inputs step information, the user may use an automatic step information display setting function. That is, when the user inputs the step information and selects the automatic step information display, an automatic setting window  6  is displayed. 
     In addition, automatic display may be specified or may not be specified in the automatic step information display  6   a.  In the automatic step information display  6   a  of  FIG. 31(B) , when “Y (yes)” is selected, the automatic display is set, and when “N (no)” is selected, the automatic display is not set. 
     In addition, when the automatic display is set, it is possible to designate a step that is automatically displayed on the display. For example, in a case where the entire step is from Step  1  to Step  5 , when Step  1  is designated as a start step in the step setting window  6   b,  and when Step  4  is designated as an end step in the step setting window  6   b,  the step information is automatically displayed only from Step  1  to Step  4 . In addition, the Step  5  information is not automatically displayed on the display, but is displayed on the display only when the stepwise operation command is executed. 
     In this case, the automatic displaying of the step information means that the step information is automatically displayed from Step  1  to Step  4  in sequence. In addition, when the time is designated in parentheses of the step setting window  6   b,  the time at which each step is displayed when the step information is sequentially and automatically displayed is designated. 
     Meanwhile, it is apparent that the automatic setting may be set not only by the user of the smartphone  110 , but also by the server operator. In addition, it is also possible to cancel the automatic display setting. That is, when the user, who desires the step information for which the automatic display setting is designated to be displayed on the display  30 , cancels the designation of the automatic display setting, the step information is not displayed automatically. 
       FIG. 32  is a view illustrating an exemplary embodiment in which speed is reflected so as to execute the stepwise operation command. 
     That is, in a case where information of Step N, which is any one step in a range from Step  1 , Step  2 , Step  3 , and Step  4  (reference numerals are  32 ,  34 ,  36 , and  38 ) or Step  1  (the lowest step) to Step K (the highest step), is displayed on the display  30 , a stepwise operation command may be executed in the direction of the arrows shown in  FIG. 32 . 
     That is, in  FIG. 32 , when the step information displayed on the display is selected and a selection point is moved in the direction of the left arrow, the step moves by one step in the lower direction (i.e., Step  1  direction). Then, when the step information displayed on the display is selected and the selection point is moved in the direction of the right arrow, the step moves by one step in the higher direction (i.e., Step K direction). 
     Meanwhile, the movement speed may be reflected. That is, when moving in the direction of the arrows, when the contact time is long (i.e., speed is slow), more steps may be moved. For example, when the time in which the selection point is moved in the direction of the arrows is 0.5 seconds or less, the step moves by one step (in the lower direction or higher direction), and when the time in which the selection point is moved in the direction of the arrows is one second, or greater than or equal to 0.5 seconds, or less than or equal to one second, the step is moved by two steps (in the lower direction or higher direction). 
     In this case, various exemplary embodiments (i.e., circular movement, angular movement, etc.) of the present disclosure are applied to the method by which the selected point is moved, and the exemplary embodiment of the present disclosure is also applied to the step movement according to a predetermined time or a predetermined range. 
     In addition, as in the exemplary embodiment of the present disclosure, even though the selection point is moved in the direction of the arrows, the step does not move further by Step  1  or less, and does not move further by Step K or more. 
       FIGS. 33 to 35  are views illustrating an exemplary embodiment in which a stepwise operation command is possibly executed in two different ways for the same selection area. 
     Referring to  FIG. 33(A) , the selection area  32  is selected, and a stepwise operation command may be executed in the method of the exemplary embodiment of  FIG. 5 . Naturally, the stepwise operation command may also be executed in the method of the exemplary embodiment of  FIG. 7 . 
     In addition, when the selection area  32  is selected and the stepwise operation command is executed as shown in  FIG. 33(B)  (as shown in Step  1  of  FIG. 33(B) , the stepwise operation command is executed in the upward and downward direction (i.e., arrow direction)), and Step  2  information  36  is displayed on the display  30 . In  FIG. 33(B) , although the Step  2  information is shown in the form of four boxes, it is not necessarily limited to the number of four. Any N number is applicable. 
     In addition, when one of four pieces of Step  2  information in  FIG. 33(B)  is selected and a stepwise operation command is executed in the leftward and rightward direction (indicated by the arrows in the leftward and rightward direction in the view), the Step  3  information is displayed on the display  30 . Similarly, in the views, the Step  3  information is indicated as three boxes, but the number is not limited to three. Any N number is applicable. 
     In addition, when one of three pieces of Step  3  information is selected, 
     the information indicated by arrows in the upward and downward direction in Step  3  of  FIG. 33(B)  is displayed, and when the stepwise operation command is executed, the Step  4  information is displayed on the display  30  as shown in  FIG. 33(C) . 
       FIG. 34  is a view illustrating an exemplary embodiment in which a stepwise operation command is executed by the method of the exemplary embodiment of  FIG. 6 . That is, by the method of the exemplary embodiment of  FIG. 33 , the selection area  32  in which the stepwise operation command is executable is selected. Then, according to the degree to which the selection area is selected and maintained for a predetermined time, the information on Step  2 , Step  3 , and higher step is displayed on the display  30 , (or the steps are divided by the magnitude of the applied pressure). 
     Consequently, for the same selection area  32 , the information “displayed on the display (hereinafter, displayed on the display by Method A) when a stepwise operation command in which the step is divided by a movement distance (or angle) is executed”, and the information “displayed on the display (hereinafter, displayed on the display by Method B) when a stepwise operation command in which the step is divided by holding time is executed” are different from each other. 
       FIG. 35  is a view illustrating an exemplary embodiment by Method A and an exemplary embodiment by Method B, which are different from each other. As an example, the Step  2  (reference numeral  34 ) information displayed on the display when Step  2  is reached by Method A, and the Step  2  (reference numeral  34 ) information displayed on the display when Step  2  is reached by Method B are different from each other for the same selection area  32  that is Step  1 . That is, when the method of executing the stepwise operation command is different, the same pieces of Step  2  (reference numeral  34 ) information are also different from each other. 
     Exemplary Embodiment When Method of Stepwise Operation Command is Different 
     1) When executing stepwise operation commands of different methods for the same selection area  32 , the pieces of information  39  of Step N, which is any one step in a range from Step  2  that is the next step of the lowest step to Step K that is the highest step, are different from each other. 
     That is, although pieces of N Step information are the same, when the methods of the stepwise operation command are different, the pieces of Step N information  39  are different from each other. 
     2) In the information displayed as a result of the method of clause 1) above, all the information on Step  2  through Step K are all not different. 
     That is, from Step  2  to Step K, when the methods of the stepwise operation command are different, there are at least one or more of steps having the information different from each other even in the same step. 
     3) In the exemplary embodiment of  FIGS. 33 to 35 , when the methods of the stepwise operation command are different, two different methods are used, but in practice, two or more different methods may be used. 
     4) The sets exist. 
     In the present disclosure, the information from the Step  1  information to the Step N information is defined as one set (where Step N is any one step from Step  2  to Step K) 
     When the stepwise operation command is executed by Method A, information from the Step  1  information to the Step N information is a first set  39   a,  and when the stepwise operation command is executed by Method B, information from the Step  1  information to the Step N information is a second set  39   b.    
     Similarly, when the stepwise operation command is executed in Method C, information from the Step  1  information to the Step N information is a third set. 
     In addition, in the first set, the second set, and the third set, the Step  1  information (i.e., Step  1  selection area)  32  is all the same. However, when the sets are different, there are at least one or more of steps having pieces of information different from each other in a range from Step  2  to Step K. Naturally, when the sets are different, the information from Step  2  to Step K may all be different (as in the view of  FIG. 35 ). 
     5) The place where the sets are stored is the memory part  21  of the smartphone, and also the database  104  of the server. 
     Accordingly, when information in the set  39   a  and  39   b  is displayed on the display  30  of the smartphone, the central processing unit  20  of the smartphone selects the information from the memory part  21  of the smartphone or displays the information received from the server on the display  30 . 
     6) An example of the method of the stepwise operation command is as follow. 
     First exemplary embodiment Method A is a method in which a point is selected and moved. Method B is a method in which a step is determined by holding time. 
     Second exemplary embodiment Method A provides upward and downward movement (i.e. one point or two points are selected). Method B provides leftward and rightward movement. In addition, Method C is a method in which the step is determined by holding time. 
     Third exemplary embodiment Method A is a method in which a point is selected and moved. Method B is a method in which a step is determined by angle so as to be moved. In addition, Method C is a method in which the step is determined by holding time. 
     Fourth exemplary embodiment Method A is a method in which two points are selected and the selected points are narrowed or widened. Method B is a method in which a step is determined by holding time. 
     Other than the methods above, other methods exist, including: a method in which a step is determined by the shape of a finger image; and a method in which a step is determined by the number of tapping of a selected area. 
     That is, there are cases in which various exemplary embodiment methods are present other than the above-described methods of the exemplary embodiment. 
       FIG. 36  is another example in which the stepwise operation command is executed in two methods with respect to the same selection area. 
       FIG. 36(A)  is a case in which a stepwise operation command is executed by the method of the exemplary embodiment of  FIG. 5 or 8  of the present disclosure. 
     When Step  1  (reference numeral  32 ) is “Newspaper” information, and when the stepwise operation command is executed in Step  1 , the newspaper company information appears as the Step  2  (reference numeral  34 ) information (i.e., table of contents). That is, “New York Times” and “Washington Post” are displayed on the display as items in the table of contents. 
     When one newspaper company (i.e., item) is selected from the Step  2  (reference numeral  34 ) information (i.e., table of contents) on the newspaper company and a stepwise operation command is executed, the Step  3  (reference numeral  36 ) information (i.e., table of contents) is displayed on the display. That is, classification information of news within a newspaper company is displayed as items such as “Main News”, “Weather”, and “Economy”. 
     In addition, although not shown in the view of  FIG. 36 , when the item “Weather” or “Main news” is selected in (Step  3 ) of  FIG. 36(A) , the selected information “Weather” or the detailed information on “Main news” is displayed on the screen of the display, or is linked to an Internet site where the selected information is displayed. 
       FIG. 36(B)  is a case in which a stepwise operation command is executed by the method of the exemplary embodiment of  FIG. 6  of the present disclosure. That is, information different from the method of  FIG. 36(A)  is displayed on the display. 
     In addition, the content or type of information displayed in each step in  FIG. 36(B)  is in accordance with the method of the exemplary embodiment of the present disclosure. 
     —Sequence of Stepwise Operation Command Displayed in Multiple Dimensions— 
     1) An example of a stepwise operation command displayed in multiple dimensions is illustrated as a case in  FIG. 36(A) . Step  1  information (i.e., selection area)  32  is selected and a stepwise operation command is executed. 
     2) When the Step  1  information (i.e., selection area)  32  is selected and the stepwise operation command is executed, a Step  2  table of contents (i.e., information)  34  is displayed. 
     The number of items in the table of contents displayed in Step  2  is related to a movement distance of a point selected in order to execute the stepwise operation command on Step  1  selection area. 
     For example, in the exemplary embodiment of  FIG. 33(B) , when moving from Step  1  to Step  2 , four items in the Step  2  table of contents (i.e., information)  34  are displayed in (Step  2 ) of  FIG. 33(B) . However, depending on the distance (i.e., the distance the point selected by the stepwise operation command moves) moved in the direction of the arrows (displayed in the upward and downward direction in the view) indicated in (Step  1 ), only two items or six items may be displayed. 
     In addition, in a case where the Step  2  table of contents (i.e., information)  34  consisting of four items in (Step  2 ) of  FIG. 33(B)  is displayed on the display, when a stepwise operation command is executed in the above state (i.e., the stepwise operation command is executed to move the selection points in the direction of the arrows indicated in the upward and downward direction in the view), the four items displayed above are increased to five items or more. (i.e., Naturally, the number of items are increased only by the maximum specified number). In addition, when the stepwise operation command is executed in the opposite directions of the arrow directions, the displayed four items may be reduced up to one item according to the movement distance of the selected point. 
     For example, when the stepwise operation command is executed in the direction in which the selected two points are widened, the number of items in the Step  2  table of contents (i.e., information)  34  increases (Naturally, the number of items is not increased more than the predetermined number). Meanwhile, when the stepwise operation command is executed in the direction in which the selected two points are narrowed, the number of items in the Step  2  table of contents (i.e., information)  34  is reduced up to one item. Naturally, the number of items to be increased or the number of items to be reduced is determined according to the predetermined movement distance. 
     3) When any one item from among the Step  2  table of contents  34  is selected and the stepwise operation command is executed, the Step  3  table of contents (i.e., information)  36  is displayed. 
     In this case, the number of items generated in Step  3  table of contents (i.e., information)  36  depends on the method in which Step  2  table of contents (i.e., information) is displayed. 
     4) When any one item of Step N table of contents is selected and the stepwise operation command is executed, Step N+1 table of contents (i.e., information) is displayed. 
     In this case, the number of items generated in the Step N+1 table of contents (i.e., information)  36  depends on the method in which the Step  2  table of contents (i.e., information) is displayed. 
     5) The “stepwise operation command displayed in multiple dimensions” is an expression that mimics the example of mathematics that displays two dimensions, three dimensions, and four dimensions. 
     That is, the “direction of the stepwise operation command” increasing the number of items in Step  1  is different from the “direction of the stepwise operation command” increasing the number of items in Step  2 . That is, the “direction of the stepwise operation command” increasing the number of items in Step N is different from the “direction of the stepwise operation command” increasing the number of items in Step N+1. 
     6) When the Step  2  information (i.e., table of contents) is selected and a stepwise operation command (i.e., the direction in which the selected point is moved) is executed in the upward and downward direction, the number of items in the Step N information (i.e., table of contents) is increased or decreased. In this case, when one item is selected from the Step N information (i.e., table of contents) and a stepwise operation command (i.e., the direction in which the selected point is moved) is executed in the leftward and rightward direction, the lower step information (i.e., lower level information in the hierarchical structure example of  FIG. 19 ) about the selected item is displayed as Step N+1 information (i.e., table of contents). In addition, the Step N+1 information (i.e., table of contents) is displayed with two or more items (i.e., as a very exceptional case, only one item is possible). 
     In addition, although the lower level information is displayed, information other than the lower level information may be displayed. 
     7) The direction in which the stepwise operation command is executed in any Step N or Step N+1 does not need to be particularly limited. 
     8) A method for using stepwise operation command displayed in multiple dimensions is exemplified. 
     A stepwise operation command in which the number of items in the table of contents increases and decreases by a movement distance to which the selected point is moved is executed. 
     In addition, when the stepwise operation command in which a step is determined by the time for which one item is selected and maintained in the table of contents is executed, an item having information different from the information of the selected item is displayed. (Alternatively, an item having information of a lower layer (refer to the exemplary embodiment of  FIG. 19 ) of the information of the selected item is displayed). 
     9) When there is only one item in the selection area (i.e., table of contents), the “method in which a stepwise operation command is executed by a movement distance” and the “method in which a stepwise operation command is executed by holding time” may be used interchangeably. 
     Exemplary Embodiment Where Two Methods of Stepwise Operation Commands are Executed for Same Selection Area 
     In the exemplary embodiment below, Method A and Method B are selected from among methods including: a method of dividing a step by time that a selected point is maintained; a method of dividing a step by a magnitude of pressure applied to the selected point; and a method of dividing a step by a distance or an angle at which the selected point moves. 
     1) First Exemplary Embodiment 
     (a) When a stepwise operation command of Method A is executed, 
     as in Step  1 , Step  2 , and Step  3 , the amount of data displayed on the display increases as the step increases. 
     When the data is increased, the amount of data is increased in a state that data existing in the previous step exists. 
     Information of the same layer (in the hierarchical structure example of  FIG. 19 ) is increased. 
     For example, the more the step increases, the more the number of items or table of contents increases. 
     For example, according to the exemplary embodiment of  FIG. 33 , “London Times” exists in Step  1 , but when a stepwise operation command is executed, “New York Times”, “Washington Post”, Korea Times”, and the like will additionally appear as Step  2 . 
     (b) When the stepwise operation command of Method A is executed, 
     as in Step  1 , Step  2 , and Step  3 , the information displayed on the display becomes different as the step increases. 
     For example, the Step N+1 information does not include the Step N information. 
     Information of the lower layer (in the hierarchical structure example of  FIG. 19 ) is displayed. 
     2) In a case where a subject of a selection area is a phone number list, 
     (a) when a stepwise operation command of Method A is executed, 
     one item (i.e., name, title, or number) is selected from the phone number list (i.e., table of contents), and a stepwise operation command is executed for the selected item. In addition, as the step increases, the data of information related to the phone number increases. 
     The phone number is additionally displayed. 
     Information related to the selected name is additionally displayed. Other phone numbers, e-mail addresses, addresses, memos, and the like are additionally displayed. 
     Information editing, and the like are additionally displayed. 
     A text function is displayed. 
     (b) When a stepwise operation command of Method B is executed, 
     A link is established for programs or content in which text and mails may be used. 
     Other programs or a table of contents other than the phone appears. 
     3) In a case where a subject of the selection area is a map, 
     (a) when a stepwise operation command of Method A is executed, 
     additional information about the map is displayed. 
     The detail level of the map is increased. 
     When a certain point (i.e., shop or restaurant) is selected on the map and a stepwise operation command is executed, information about additional shops or restaurants is displayed. 
     For example, in a case where there is a plurality of shops or restaurants at a point (which may be generally a building or a place), when a stepwise operation command is executed, the number of shops or restaurants displayed on the display increases. 
     (a) In a case where a stepwise operation command of Method B is executed, 
     when a specific point (i.e., shop or restaurant) is selected on the map and a stepwise operation command is executed, additional information about the selected point is displayed. 
     The additional information above is the products or menus handled by the above-mentioned stores or restaurants. 
     A window for ordering the products or menus is displayed. 
     A window for payment for the products or menus is displayed. 
     A window for transmitting a message to the stores or restaurants is displayed. 
     A window for sending an e-mail to the stores or restaurants is displayed. 
     4) In a case where a subject of the selection area is an icon, 
     the icon is in accordance with the “method for executing the multi-dimensionally displayed stepwise operation command”, the method being described in the previous exemplary embodiment of the present disclosure. 
       FIG. 37  is a view illustrating an exemplary embodiment illustrating a stepwise operation command having a two-dimensional step. 
       FIG. 37(A)  is a view illustrating an exemplary embodiment in which each step of information is shown in a two-dimensional method or a three-dimensional method. 
     An initial Step  1  (i.e., Step  1 - 1 ) is present, and Step  2 , Step  3 , Step  4 , or Step N is displayed according to the magnitude of the applied value. 
     In addition, in Step  1 , Step  1 - 1 , Step  1 - 2 , Step  1 - 3 , step  1 - 4 , or step  1 -N is present 
     In addition, in Step  2 , Step  2 - 1 , Step  2 - 2 , Step  2 - 3 , Step  2 - 4 , or step  2 -N is present as well. 
     Similarly, even in Step N, Step N- 1 , Step N- 2 , Step N- 2 , step N- 4 , or step N-N is present. 
     The method of the stepwise operation command by which the step is moved to Step  1  (Step  1 - 1 ), Step  2  (Step  2 - 1 ), Step  3  (Step  3 - 1 ), Step  4  (Step  41 ), or Step N (Step N- 1 ) may be called Method A. In addition, the method of the stepwise operation command by which the step is moved to Step N- 1 , Step N- 2 , Step N- 3 , Step N- 4 , or Step N-N may be called Method B. 
     In addition, the method used as the stepwise operation command in the present disclosure includes pressure, time, distance movement, angle movement, and the like. 
     Therefore, as a first exemplary embodiment, Method A may be a method of applying the intensity of pressure, and Method B may be a method of applying holding time. 
     In addition, as a second exemplary embodiment, Method A may be a method of the holding time, and Method B may be a method of distance movement. 
     In addition, as a third exemplary embodiment, Method A may be a method of applying speed, and Method B may be a method of the distance movement. 
     In addition, as a fourth exemplary embodiment, Method A may be a method of “distance movement in a rightward (or leftward) direction, i.e., horizontal direction”, and Method B may be a method of “distance movement in a downward (or upward) direction, i.e., vertical direction”. 
     That is, a combination of the numbers of various cases is possible so that Method A and Method B are not the same. 
     In addition, the result of the stepwise operation command is as follows. 
     When a step is moved by two steps in Method A and the step is moved by three steps in Method B, the icon of Step  2 - 3  is displayed on the display. 
     As another example, when a step is moved by N steps in Method A and the step is moved by N steps in Method B, the icon of the Step N-N is displayed on the display. 
     In addition, the characteristics (or summary) of information of each step is displayed in the icon of Step  2 - 3  or Step N-N. The descriptions of characteristics (or summary) of information are described in the exemplary embodiments of  FIGS. 9 and 10  of the present disclosure. 
     In addition, when a user desires to check the information of Step  2 - 3  or Step N-N in more detail, the user may select the icon of Step  2 - 3  or Step N-N, (i.e., selecting on the display through an input device) 
       FIG. 37(B)  is a view illustrating another exemplary embodiment in which each step of information is shown in a two-dimensional method or a three-dimensional method. 
     In Step  1 , when a selection area  32  is selected on the display through an input device, a guiding line is displayed on the display, and the guiding line  50  indicates the characteristics (or summary) of information for each step. 
     In addition, when a stepwise operation command is input by the guide of the guiding line  50 , information corresponding to the final step (i.e., Step  2 ,  3 ,  4 , or N) generated by the stepwise operation command is displayed in a separate window  97 . 
     Even at this time, Method A and Method B described in the exemplary embodiment of  FIG. 37(A)  exist, so as to allow the information of Step N-N to be displayed in a separate window. 
     Meanwhile, when executing the stepwise operation command, Method A or Method B may be displayed on the display. 
     —Step of Three Dimensions— 
     Even in Step  1 - 1  (Step  1 - 1 - 1 ), Step  1 - 1 - 2 , Step  1 - 1 - 3 , Step  1 - 1 - 4 , or Step  1 - 1 -N is present. 
     In addition, in Step  2 - 2  (Step  2 - 2 - 1 ), Step  2 - 2 - 2 , Step  2 - 2 - 3 , Step  2 - 2 - 4 , or Step  2 - 2 -N is present. 
     Similarly, in Step N-N, Step N-N- 1 , Step N-N- 2 , Step N-N- 3 , Step N-N- 4 , or Step N-N-N is present. 
     That is, when a step movement in a one-dimensional direction is called Method A, and a step movement in a two-dimensional direction is called Method B, a step movement in a three-dimensional direction may be called Method C. A stepwise operation command in Method C may also be executed in accordance with the method of the stepwise operation command of Method A and Method B. 
     In addition, when viewed hierarchically, it may be said that when information movement in the same layer is called Method A and information movement in a direction lower by one layer is called Method B, information movement in a direction lower by two layers may be called Method C. The description of the hierarchical structure is in accordance with the exemplary embodiments of  FIGS. 19 and 20  of the present disclosure. 
       FIGS. 38 and 39  are views illustrating an exemplary embodiment in which two or more displays are provided. 
     As shown in  FIG. 38 , a first display  30 - 1  and a second display  30 - 2  are provided, and first and second display driving circuits  25 - 1  and  25 - 2  are also provided. 
     In addition, a first input device  28 - 1  is provided in the first display, and a second input device  28 - 2  is provided in the second display. In addition, first and second input device driving parts  27 - 1  and  27 - 2  for driving the input devices are provided. 
     In this case, the two displays  30 - 1  and  30 - 1  and the two input devices  28 - 1  and  28 - 2  are controlled by a single central processing unit  20 . 
       FIG. 39  is a view showing an exemplary embodiment in which a stepwise operation command is displayed on two displays. That is, when a stepwise operation command is executed on the first display  30 - 1 , the results of the execution are displayed on the second display  30 - 2 . Naturally, when a stepwise operation command is executed on the second display, the results of the execution may be displayed on the first display. 
     For example, when a selection area (i.e., current Step  1 ) is selected on the first display  30 - 1  and is moved by two steps through the stepwise operation command, the final step is Step  3 , and information corresponding to Step  3  is displayed on the second display  30 - 2 . 
     The function of  FIG. 39  may be executed on the central processing unit of the smartphone (or the controller of the server) by an algorithm stored in the memory part of the smartphone (or the database of the server). That is, information corresponding to the final step, selected as a result of executing the stepwise operation command input through the first input device  28 - 1  provided in the first display, is displayed on the second display. 
     Meanwhile, when step information input is selected through the first display  30 - 1 , the input window  45  is displayed on the second display  30 - 2 , so that the user of the present disclosure uses the smartphone  110 , whereby information corresponding to the step may be input. That is, the information corresponding to the step is input into the input window  45 . 
     In addition, when the step input  42  is selected through the first display  30 - 1 , the selection window  40  is displayed as shown in the exemplary embodiment of  FIG. 25(A) . 
     As in the previous description, when a step is increased, data may be increased or decreased compared to a previous step, new data not present in the previous step may be added, or information of the new step may be displayed only with information that did not exist in the previous step. In addition, each step is displayed on the display through the stepwise operation command, and even though the stepwise operation command is executed, each step may not proceed further lower than the lowest step or higher than the highest step. 
     The present disclosure provides a wide variety of exemplary embodiments. In addition, the smartphone, the server, and the method of the stepwise operation command, which are the basis for implementing the exemplary embodiment, may be applied to each other in each exemplary embodiment. 
     Providing one or two examples, in the present disclosure, the selection region is an area in which a stepwise operation command may be executed, and the area may use only a part of the entire screen as a target area or the area may use the entire screen (except for areas where menus, and the like are displayed, even in the entire screen) as the target area. Then, the concept of the selection area is applied to all exemplary embodiments of the present disclosure. 
     In addition, when there is a concept that “the initial Step  1  should be a selection area, but from Step  2  to Step K that is the highest step, there is no selection area and Step N (i.e., any one step from Step  2  to Step K) in which only the information of the corresponding step is displayed also exists”. the above concept is also applied to all exemplary embodiments of the present disclosure. 
       FIG. 40  is a view illustrating an exemplary embodiment in which the present disclosure is applied to a map. 
       FIG. 40  is a view illustrating an exemplary embodiment in which the first display and the second display exist. Alternatively, in the exemplary embodiment of  FIG. 40 , one display is divided into two areas so that the display may be applied as it is even when there are the first area and the second area. 
     A map is displayed on the first display  30 - 1  (or the first area), and a selection area  32  exists in the map. The selection area may be a shop, a station, or a specific place of a building in the map. 
     In addition, the selection area  32  is then selected and a stepwise operation command is executed. Then, the execution result of the stepwise operation command is displayed on the second display  30 - 2  (or the second area). 
     In the exemplary embodiment of  FIG. 40 , a menu is displayed, and a view of an exemplary embodiment in which an order may be placed through the menu is illustrated. 
     In this case, the stepwise operation command may be executed for the entire first display  30 - 1  (or the first area). In the present disclosure, the described method is a method of dividing a distance into steps. In this case, the execution result of the stepwise operation command is displayed on the first display  30 - 1  (or the first area) as it is. 
     However, the stepwise operation command may be executed on the selection area  32  existing in the first display  30 - 1  (or the first area). The stepwise operation command is a method of dividing the length of time into steps or dividing the magnitude of pressure into steps. In this case, the result of the stepwise operation command is displayed on the second display  30 - 2  (or the second area). 
     In addition, a selection area  34   a  may exist in the second display  30 - 2  (or the second area). When the stepwise operation command is executed on the selection area  34   a  existing in the second display  30 - 2  (or the second area), the result may be again displayed on the first display  30 - 1  (or the first area). 
     When the stepwise operation command is executed on the first display  30 - 1  (or the first area), the results may appear on the first display (or the first area), and the results may appear on the second display (or the second area). In addition, when the stepwise operation command is executed on the second display  30 - 2  (or the second area), the results may appear on the second display (or the second area), and the results may appear on the first display (or the first area). 
     In the case where the stepwise operation command is executed on the first display  30 - 1  (or the first area), when the stepwise operation command is executed in Method A, the results is displayed on the first display  30 - 1  (or the first area), and when the stepwise operation command is executed in Method B, the results is displayed on the second display  30 - 2  (or the second area). 
     In addition, when the stepwise operation command is executed for all information displayed on the first display  30 - 1  (or the first area), the result is displayed on the first display  30 - 1  (or the first area). Then, when the stepwise operation command is executed on the selected area displayed on the first display  30 - 1  (or the first area), the result is displayed on the second display  30 - 2  (or the second area). 
     That is, the central processing unit  20  displays the result on the first display and the second display according to the algorithm (i.e., method) described in the exemplary embodiment of  FIG. 40 . Alternatively, the central processing unit  20  displays the result on the first and second areas of the display  30  according to the algorithm (i.e., method) described in the exemplary embodiment of  FIG. 40 . 
       FIGS. 41 to 42  are views illustrating another exemplary embodiment using two displays. 
     Meanwhile, the exemplary embodiments of  FIGS. 41 and 42  may be applied as it is even when the first area and the second area are displayed on one display. 
     The exemplary embodiment is for a case where any initial information (i.e., a map in the exemplary embodiment of  FIG. 41 ) is displayed over the entire two displays  30 - 1  and  30 - 2  (or when displayed on one display  30 ), and the embodiment method is as follows. 
     (1) For initial information (i.e., a map in the exemplary embodiment of  FIG. 41 ) displayed on the two displays  30 - 1  and  30 - 2  (or one display  30 ), when a stepwise operation command that divides a distance into steps or a stepwise operation command that divides an angle into steps is executed, the result of the stepwise operation command is displayed on the two displays  30 - 1  and  30 - 2  (or one display  30 ). 
     (2) In a case where the selection area (i.e., the shop, restaurant, or building in the map in the exemplary embodiment of  FIG. 41 ) exists in the initial information (i.e., the map in the exemplary embodiment of  FIG. 41 ) displayed across the two displays  30 - 1  and  30 - 2  (or one display  30 ), when the stepwise operation command is executed for the selected area, the result is displayed as in the exemplary embodiment of  FIG. 40 . 
     The steps includes: Step  1  in which a selection area within the initial information displayed across the two displays  30 - 1  and  30 - 2  (or one display  30 ) is selected as a point through the input device, so as to execute a stepwise operation command for the selection area; 
     Step  2  in which a position of a point is output from the input device to the central processing unit; 
     Step  3  in which the central processing unit determines a final step that is moved from a current step of the selection area; and 
     Step  4  in which the central processing unit causes the initial information to be displayed on the first display  30 - 1  (or the first area) and the second display  30 - 2  (or the second area) displays the information on the final step of the selection area determined in Step  3  above. (In the exemplary embodiment of  FIG. 40 , it may be said that the result of Step  4  is displayed on the second display  30 - 2  (or the second area)). 
     Thus, the above-described steps are included. 
     Naturally, the initial information is allowed to be displayed on the second display  30 - 2  (or the second area), and the information on the final step of the selection area determined in Step  3  may be displayed on the first display  30 - 1  (or the first area). 
     In this case, in Step  3 , the central processing unit determines the final step that is moved from the current step by means of the time for which a point of Step  1  is maintained or the intensity of the pressure applied through the point. 
     In addition, in Step  4 , when a stepwise operation command is executed, the stepwise operation command dividing a distance or an angle into steps for information displayed on the second display (or second area) (refer to the view of the exemplary embodiment of  FIG. 40 ), the result of the stepwise operation command is displayed on the second display (or second area). 
     Meanwhile, in Step  4 , when the selection area exists in the information displayed on the second display (or second area) and the stepwise operation command is executed on the selected area, the result is displayed on the first display (or the first area) (refer to the exemplary embodiment of  FIG. 42 ). 
     That is, in  FIG. 42 , a table of contents for food is displayed. In addition, an item (“Chicken salad” in the exemplary embodiment of  FIG. 42 ) among the table of contents for the food may be the selection area. Then, when the stepwise operation command for dividing time or pressure into steps is executed for the item (“Chicken salad” in the exemplary embodiment of  FIG. 42 ), the result is displayed on the first display (or first area). 
       FIGS. 43 to 48  are views illustrating examples of a foldable smartphone. 
     That is, in the folded state of a smartphone, an external display  30 - 3  is present outside, and in the unfolded state of the smartphone, the internally unfolded display  30  (or the first display and the second display) is present. 
     In addition, the method of controlling the external display  30 - 3  by the central processing unit  20  is the same as the method of controlling the display  30  and the first and second displays  30 - 1  and  30 - 2 . 
     (1) For initial information (i.e., a map in the exemplary embodiment of  FIG. 44 ) displayed on the external display  30 - 3 , when a stepwise operation command that divides a distance into steps or a stepwise operation command that divides an angle into steps is executed, the result of the stepwise operation command is displayed on the external display  30 - 3 . 
     (2) In the case where the selection area exists in the initial information (i.e., the map in the exemplary embodiment of  FIG. 44 ) displayed on the external display  30 - 3 , when a stepwise operation command is executed for the selection area, a screen is divided and displayed. In addition, the steps are as follows: 
     Step  1  in which a selection area in initial information is selected by a point through an input device, and a stepwise operation command is executed on the selection area; 
     Step  2  in which a position of the point from the input device is output to the central processing unit; 
     Step  3  in which a central processing unit determines a final step moved from a current step of the selection area; and 
     Step  4  in which the central processing unit causes the initial information (i.e., the map in the exemplary embodiment of the present disclosure) to be displayed on a part of the external display  30 - 3 , and causes the information on the final step of the selection area determined in Step  3  to be displayed on another part of the external display  30 - 3  (i.e., a separate window  30   d - 1  in the exemplary embodiment of  FIG. 48 ). 
     Thus, the above-described steps are included. 
     In this case, in Step  3 , the central processing unit  20  determines the final step that is moved from the current step by means of the time for which a point of Step  1  is maintained or the intensity of the pressure applied through the point. 
     Meanwhile, when the smartphone is unfolded, there is a display therein (refer to the exemplary embodiment of  FIG. 45 ), and the display  30  inside is divided, so that the initial information (i.e., a map in the exemplary embodiment of the present disclosure) and the Information on the final step of the selection area determined in Step  3  are simultaneously displayed. (i.e., the exemplary embodiment of  FIG. 46 ). 
     Another Application of Exemplary Embodiment of FIG.  46   
     The exemplary embodiment of  FIG. 46  may be applied as it is even when the first display  30 - 1  and the second display  30 - 2  exist. 
     That is, when a foldable display in which an external display  30 - 3  exists is unfolded, a first display and a second display may exist therein. 
     That is, when the smartphone is unfolded, the initial information (i.e., the map in the exemplary embodiment of the present disclosure) is displayed on the first display (or second display), and the information on the final step of the selection area determined in Step  3  is displayed on the second display (or the first display). (i.e., the exemplary embodiment of  FIG. 46 ). 
     —Describing Process in Steps— 
     (1) When the foldable smartphone is unfolded, the display  30  is present inside the smartphone. For the initial information (i.e., the map in the exemplary embodiment of  FIG. 45 ) displayed on the display  30 , when a stepwise operation command that divides a distance into steps or a stepwise operation command that divides an angle into steps is executed, the result of the stepwise operation command is displayed on the display  30  that is unfolded. 
     (2) In the case where the selection area exists in the initial information (i.e., the map in the exemplary embodiment of  FIG. 45 ) displayed on display  30  that is unfolded, when a stepwise operation command is executed for the selection area, a screen is divided and displayed. For example, as shown in  FIG. 47 , the pieces of information is respectively displayed in the first area  30   a  (or the first display) and the second area  30   b  (or the second display). In addition, the execution steps are as follows: 
     Step  1  in which a selection area in initial information (i.e., a map in the exemplary embodiment of  FIG. 45 ) is selected as a point through an input device, and a stepwise operation command is executed for the selected area; 
     Step  2  in which a position of the point from the input device is output to a central processing unit; 
     Step  3  in which the central processing unit determines a final step moved from a current step of the selection area; and 
     Step  4  in which the central processing unit causes the initial information to be displayed on a part (i.e., first area  30   a  of the display  30 ) (or first display) that is unfolded, and causes the information on the final step of the selection area determined in Step  3  to be displayed on another part (i.e., second area  30   b  of the display  30 ) (or second display) that is unfolded. (The result of Step  4  may refer to the exemplary embodiment of  FIG. 46 ). 
     Thus, the above-described steps are included. 
     In this case, in Step  3 , the central processing unit determines the final step that is moved from the current step by means of the time for which a point of Step  1  is maintained or the intensity of the pressure applied through the point. 
     In addition, the exemplary embodiment of  FIG. 47  may be implemented. That is, information on the final step of a selection area determined in Step  3  is displayed on the second area  30   b  (or the second display), the selection area exists in the second area  30   b  (or the second display), and when a stepwise operation command is executed on the selected area, a new window  34 - 1   a  is generated, so that the execution result of the stepwise operation command is displayed in the new window  34 - 1   a.    
     That is, the case is the exemplary embodiment of  FIG. 47 . In  FIG. 46 , a table of contents for food is displayed in the second area  30   b  (or the second display). In addition, an item (“Chicken salad” in the exemplary embodiment of  FIG. 46 ) among the table of contents for the food may be the selection area. Then, when the stepwise operation command for dividing time or pressure into steps is executed for the item (i.e., selection area), the result is displayed in a new window  34 - 1   a  (refer to the exemplary embodiment of  FIG. 47 ). 
     —Case Where Two Displays Exist Inside Foldable Display— 
     When a smartphone of the present disclosure is unfolded, two displays  30 - 1  and  30 - 2  appear. In addition, when the smartphone of the present disclosure is folded, an external display  30 - 3  is present. That is, the external display  30 - 3  exists outside the smartphone (refer to the exemplary embodiment of  FIG. 43 ), and two displays  30 - 1  and  30 - 2  exist inside the smartphone. 
     In addition, when the stepwise operation command for dividing a distance or an angle into steps is executed for the initial information (i.e., the map in the exemplary embodiment of  FIG. 44 ) displayed on the external display  30 - 3 , the result is displayed on the external display  30 - 3 . In addition, when the stepwise operation command for dividing time or pressure into steps is executed for the selected area  32  in the initial information (i.e., the map in the exemplary embodiment of  FIG. 44 ), a separate window  30   d - 1  is generated and the result of the stepwise operation command dividing the time or pressure into the steps is displayed on the separate window  30   d - 1 . 
     In addition, when the smartphone is unfolded, the central processing unit causes the initial information to be displayed on the first display  30 - 1 , and the information displayed on the separate window  30   d - 1  is displayed on the second display  30 - 2 . 
     Meanwhile, the previous exemplary embodiment of the present disclosure as it is applied to the method of displaying information on the two displays  30 - 1  and  30 - 2  that appear when the smartphone is unfolded. 
     Conversely, in the unfolded state of the smartphone, the pieces of information is respectively displayed on the two displays  30 - 1  and  30 - 2 . When the smartphone is folded (i.e., closed), the central processing unit causes the information displayed on the first display  30 - 1  to be displayed on some area of the external display  30 - 3 , and causes the information displayed on the second display  30 - 2  to be displayed on the separate window  30   d - 1 . (refer to the exemplary embodiment of  FIG. 48 ). 
     The method of displaying information on the first display and the second display, or the method of displaying the information by dividing the screen into the first area and the second area in one display, which are applied in the present disclosure, uses conventional methods. That is, the present disclosure uses the conventional methods of displaying the information on two displays, or the conventional methods of displaying the information by dividing the display screen.
