Description

  The present invention relates to an information processing apparatus, an information processing method, and an information processing program that output content data in response to a user operation.

  With the development of information communication technology, ICT (Information and Communication Technology) equipment has come to be used in various everyday situations. As the market grows, input interfaces such as mice, keyboards, remote controls, and touch panels are diversifying. In addition, due to the progress of an aging society, ICT devices and services having an interface that takes into account the elderly are also appearing with the rapid increase in the population of the elderly who use the Internet.

  However, there are users who find it difficult to operate ICT equipment. For example, it is difficult for an elderly person who has a sense of fingers or muscle weakness due to aging to operate an interface such as a mouse that requires precise operation as intended by the user. Elderly people have difficulty aiming the mouse pointer at the intended hyperlink due to hand tremors. Also, even if the mouse pointer can be aimed at the intended hyperlink, the mouse may move incorrectly when a click is performed due to excessive force. As a result, an operation error may occur in which a hyperlink different from the intended hyperlink is clicked.

  Countermeasures against this problem are implemented by a technique for reducing the sensitivity of the user's input, a technique for removing the influence of tremors, and a correction instrument that enables operation with less force (see, for example, Patent Document 1). .)

  In addition, the touch panel interface that has been rapidly spreading in recent years is difficult to use even for people with large fingers. When using the web using a touch panel interface, if the hyperlink that the user wants to press is close to the hyperlink that the user does not intend to press, it may be difficult to press only the hyperlink intended by the user.

  For this problem, measures such as the installation of a screen enlargement function and the enlargement of the area of a button that accepts a single input are considered, and an appropriate button size is also being studied (for example, non- (See Patent Document 1).

  In addition, a user who is unaccustomed to using the ICT device may find it difficult to operate. For example, there may be a case where the user cannot understand where the operation target for receiving an input such as a hyperlink is located. Further, there may be a case where the user does not know whether the device is responding to the input.

  For these problems, a technique for returning physical feedback to the user has been proposed (for example, see Patent Document 2).

Nishimura, Seo, Doi, “Relationship between switch components and pointing characteristics in one-touch operation of touch screen”, HIS2010, Sep. 2010.

  However, in any of the above prior art documents, it cannot be said that the difficulty of the user when using the ICT equipment has been completely solved.

  For example, an elderly person may experience a decrease in short-term memory capacity or a decrease in attention function due to a decline in cognitive function with aging. As a result, the elderly person recognizes the target hyperlink and may press another hyperlink even if physical feedback exists.

  Undesired content is displayed due to such a mistake operation. Although the user displays the original content and tries to press the intended hyperlink, the user may press the unintended hyperlink again. As described above, if the intended operation cannot be performed and the operation is repeated many times, a large burden may be imposed on the user.

  In addition, the use of a touch panel interface in which a user's finger is an interface is particularly difficult for elderly people who have finger sensations and muscle weakness due to aging. When operating the web browser of the touch panel information terminal to use the Internet, there is a case where the user presses a hyperlink different from the intended hyperlink repeatedly with the trembling of the finger due to finger sensation and muscle weakness. Even when the intended hyperlink can be pressed correctly, the touch panel may not be able to recognize the intended hyperlink pressed due to problems such as drying of the fingertips associated with aging. As a result, the use of the touch panel interface may cause a large psychological burden.

  Further, the enlargement function and the enlargement of the button size in the touch panel interface also reduce the amount of information that can be displayed on the screen. As a result, the information listability may be lost.

  Accordingly, an object of the present invention is to provide an information processing apparatus, an information processing method, and an information processing program that output content data that prevents a user from making mistakes continuously.

  Next, embodiments of the present invention will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals.

(First embodiment)
An information processing apparatus 1 according to the first embodiment shown in FIG. 1 is an information terminal such as a computer such as a desktop computer or notebook computer, a tablet terminal, or a smartphone. The information processing apparatus 1 includes a storage device 10, a central processing control device 20, an input / output interface 30, an input device 40, a communication control device 50, and an output device 60. By installing an information processing program for realizing a predetermined function in such a general information terminal, the information terminal becomes the information processing apparatus 1 that functions as each unit shown in FIG.

  The input device 40 is a mouse, a keyboard, a touch panel, or the like, and inputs an instruction to the information processing device 1. The embodiment of the present invention is particularly suitable for an information terminal including an input device 40 such as a mouse or a touch panel that can specify arbitrary coordinates on a screen by a user operation. User operations include selection of hyperlinks using a mouse or touch panel, button presses, tap operations on the touch panel, and character input using a keyboard.

  The communication control device 50 connects the information processing device 1 to the content providing device 2 via the communication network 3. The communication network 3 is the Internet or the like, and connects a plurality of information terminals so that they can communicate with each other. The content providing device 2 is a so-called web server, and provides content data to be displayed on the information processing device 1 by a web browser. For example, the content providing apparatus 2 receives a URL (Uniform Resource Locator) from the information processing apparatus 1 and transmits content data identified by the URL to the information processing apparatus 1.

  The output device 60 is a display device, a speaker, or the like, and outputs the processing result of the information processing device 1. The input / output interface 30 is an interface for data input / output between the input device 40, the communication control device 50 and the output device 60, and the central processing control device 20.

  The storage device 10 is a hardware disk, ROM, RAM, or the like. The storage device 10 is storage means for storing data processed by the central processing control device 20. The central processing control device 20 is processing means for processing data stored in the storage device 10 and inputting / outputting data to / from the input device 40, the communication control device 50 and the output device 60 via the input / output interface 30.

  The information processing apparatus 1 according to the first embodiment of the present invention shown in FIG. 1 outputs content data in response to a user operation. The user inputs a URL using a keyboard and performs an operation of selecting a hyperlink associated with the URL and displayed on the screen with a mouse, a touch panel, or the like. The information processing apparatus 1 acquires content data corresponding to the user's operation from the content providing apparatus 2 and displays it on the output apparatus 60. At this time, if the user cannot perform the intended operation on the web browser and an error operation occurs, the information processing apparatus 1 stores the content data so that it is easy to operate an operation object other than the operation object of the user error operation. Modify and display.

  Here, the “operation target” is an object that constitutes a screen output to the output device 60 and is an operation target by the input device 40. Specifically, the operation target is a hyperlink, a button, a scroll bar, or the like displayed on the web browser. “Miss operation” is to input an operation different from the intended operation that was input by mistake while trying to perform the operation intended by the user. In the embodiment of the present invention, it is determined whether or not the operation input from the user is a miss operation with a predetermined logic.

  The information processing apparatus 1 sequentially stores operations input by the user on the web browser. When a predetermined user operation occurs within a predetermined time from an arbitrary user operation, the information processing apparatus 1 determines that the arbitrary user operation is a miss operation. At this time, the information processing apparatus 1 according to the embodiment of the present invention determines that the operation target displayed near the operation target in which the error operation has occurred is the intended operation target. The information processing apparatus 1 modifies the content data so as to easily operate the operation target other than the operation target in which the error operation has occurred, and outputs the content data to the output device 60.

  In particular, the information processing apparatus 1 according to the first embodiment modifies content data so that it cannot be operated on an operation target in which a mistake operation has occurred. For example, the information processing device 1 deletes a hyperlink in which a mistake operation has occurred, and modifies the content data so that a display without a hyperlink is provided. As a result, the user cannot operate the operation target in which the miss operation has occurred, and thus the information processing apparatus 1 can avoid the user from inducing the miss operation again.

  For example, the information processing apparatus 1 first displays the screen shown in FIG. The screen shown in FIG. 2 is a browser screen displayed on the display unit 100 of the output device 60.

  The display unit 100 includes a content display unit 101, a return button B101, and a function switching button B102. The content display unit 101 is provided with three links L1 to L3 that are to be operated by the user. The user can select an arbitrary position of the content display unit 101 of the web browser using the input device 40. When the user selects the first link L1, the information processing apparatus 1 displays the content data “A test” on the content display unit 101. When the user selects the second link L2, the information processing apparatus 1 displays the content data “B test” on the content display unit 101. When the user selects the third link L3, the information processing apparatus 1 can display the content data “C test” on the content display unit 101.

  The return button B101 is a button for displaying the content displayed immediately before the currently displayed content. The return button B101 is effectively processed if an operation such as clicking on a hyperlink is input in the previously displayed content. For example, even before the display of new content is completed, the information processing apparatus 1 can cancel the click of the hyperlink and display the previous content.

  Here, when the user presses the first link L 1, the information processing apparatus 1 displays the content data “A test” on the output device 60. However, when the first link L1 is not the intended hyperlink, the user presses the return button B101 again to press the intended hyperlink. In the first embodiment, when the information processing apparatus 1 repeats the pressing of an arbitrary hyperlink and the pressing of the return button B101 a predetermined number of times within a predetermined time, the information processing apparatus 1 misses the pressing of the first link L1. Judge as operation. The information processing apparatus 1 modifies the content data so as not to provide the first link L1 that is accidentally pressed.

  Specifically, the information processing apparatus 1 displays the screen shown in FIG. The content display unit 102 of the screen shown in FIG. 3 deletes the hyperlink attached to the “A test” that is accidentally pressed by the user, and displays the first character string M1 of “A test”. In this way, since the hyperlink of “A test” that is operated by the user by mistake is deleted, the user does not click “A test” on the screen shown in FIG. Thereby, the information processing apparatus 1 according to the first embodiment makes it easy to select an operation target intended by the user.

  The function switching button B102 is a button for canceling the modification performed by the information processing apparatus 1. As illustrated in FIG. 3, when the user presses the function switching button B <b> 102 while the content data from which the “A test” hyperlink is deleted is displayed, the information processing apparatus 1 displays the screen illustrated in FIG. 2. indicate. The screen shown in FIG. 2 is a screen in which a hyperlink “A test” is provided and “A test” can be clicked.

(Information processing method)
With reference to FIG. 4, an information processing method according to an embodiment of the present invention will be described. FIG. 4 illustrates processing of the information processing device 1 when the information processing device 1 displays a web browser on the output device 60.

  First, the information processing apparatus 1 displays content data including a plurality of operation targets on the output device 60 on the output device 60. The screen displayed here is, for example, the screen shown in FIG.

  In step S1, when the user operates any of the operation targets of the content being displayed via the input device, in step S2, the information processing apparatus 1 acquires an identifier of the user operation target. At this time, the information processing apparatus 1 stores the identifier of the operation target of the user and the time in the operation record data 11 in association with each other.

  Here, the operation target of the content is the first link L1 to the third link L3 in the example shown in FIG. For example, when the user performs an operation of clicking the first link L1, the information processing apparatus 1 displays “first line <a href=“Atest.html”> A test </ The operation content data of “click a>” is stored in association with the time. The information processing apparatus 1 records the operation content every time the user operates the input device 40. The operation target identifier is an identifier for identifying a plurality of operation targets included in the content data.

  Next, in step S3, the information processing apparatus 1 determines whether or not the operation in step S1 is a miss operation. The information processing apparatus 1 reads the operation record data, and determines that the operation of the arbitrary user is a mistake operation when the operation of the predetermined user occurs within a predetermined time from the operation of the arbitrary user. The process for determining a miss operation will be described in detail later.

  In step S4, if the result of determination in step S3 is that the user operation is a mistake operation, in step S5, the information processing apparatus 1 modifies the content displayed in step S1. This modification is a modification for facilitating operation of an operation object other than the operation object of the mistake operation.

  On the other hand, if the user operation is not a mistake operation in step S4, in step S6, the information processing apparatus 1 acquires new content data in accordance with the operation in step S1. Specifically, the information processing apparatus 1 acquires content data corresponding to a hyperlink that is a user's operation target. Here, when the storage device 10 does not store the content corresponding to the hyperlink to be operated by the user as a cache, the information processing device 1 acquires content data from the content providing device 2. On the other hand, when the storage device 10 stores content corresponding to a hyperlink that is a user's operation target as a cache, the information processing device 1 acquires content data from the storage device 10.

  In step S <b> 7, the information processing apparatus 1 displays new content data on the output device 60. When there is a mistake operation, the information processing apparatus 1 outputs the content data modified in step S5. If there is no mistaken operation, the information processing apparatus 1 outputs the content data acquired in step S6.

  If it is determined in step S8 that the function switching button B102 in FIG. 3 has been pressed, the process proceeds to step S9. The function switching button B102 is a button that is enabled when the content data modified in step S5 is displayed. When the function switching button B102 is pressed, the process proceeds to step S9, and the information processing apparatus 1 cancels the modification in step S5 and displays the content data before the modification on the output device 60. If the function switching button B102 is not pressed, the process returns to step S1 to wait for an operation on the content data being displayed.

(Information processing device)
With reference to FIG. 1, functions implemented in the information processing apparatus 1 will be described in detail.

  The storage device 10 stores operation record data 11, miss operation data 12, content accumulation data 13, and modified content data 14. Each means mounted on the central processing control device 20 stores the operation record data 11, the miss operation data 12, the content accumulation data 13 and the modified content data 14 in the storage device 10 for reference.

  The central processing control device 20 includes an operation acquisition unit 21, an operation recording unit 22, a mistake operation determination unit 23, a content acquisition unit 24, a content modification unit 25, and a content output unit 26.

  The operation acquisition unit 21 acquires the identifier of the operation target of the user. Specifically, when the output device 60 displays content data including a plurality of operation targets, and the user operates one of the plurality of operation targets via the input device 40, the operation acquisition unit 21 displays the user's operation data. Get the identifier of the operation target. User operations acquired by the operation acquisition unit 21 include character input, hyperlink selection, scroll button movement, and the like by keyboard input, mouse click, touch panel tap operation, and the like.

  The operation recording unit 22 associates the identifier of the user's operation target acquired by the operation acquisition unit 21 with the time, and stores them in the operation record data 11. Here, the “time” is the time when the user operates the operation target, and is the time acquired from the clock function (not shown) built in the information processing apparatus 1 when the user operates.

  The operation record data 11 is, for example, operation log data as shown in FIG. The operation recording unit 22 generates a record associating the URL of the operation, the operation data of the user, and the data of each item of time each time the user operates. The operation recording unit 22 inserts the generated record into the operation record data 11.

  The “URL where the operation has occurred” item is an identifier of content data to be operated by the user. In the example shown in FIG. 5A, the content data displayed by the output device 60 is identified by the data of the “URL where the operation has occurred” item. “Time” is data of time operated by the user.

  The “user operation data” item is data for specifying a user operation. In the example shown in FIG. 5A, the user's operation data item is set to “input URL http://www.example.net/index.html”. This indicates that the user has entered “http://www.example.net/index.html” as the connection destination URL from the keyboard in the text box. When the user operates a predetermined hyperlink in the content data, the operation data item of the user sets data including the identifier of the hyperlink to be operated and the operation content. As the user operation data item, for example, as shown in the first line of FIG. 5B, “click first line <a href=“Atest.html”> A test </a>” is set. When the user further presses the return button, the user's operation data item is set to “click [return on browser]” as shown in the third line of FIG. 5C, for example.

  The miss operation determination means 23 reads the operation record data 11 and determines whether or not the user operation is a miss operation. When a predetermined user operation occurs within a predetermined time after an arbitrary user operation, the miss operation determination unit 23 determines that the arbitrary user operation is a misoperation. When it is determined that the operation is a miss operation, the miss operation determination unit 23 stores the identifier of the operation target of the miss operation in the miss operation data 12. The miss operation determination unit 23 may include an identifier of content data in which a miss operation has occurred, such as a URL, in the miss operation data 12.

  Here, the “arbitrary operation” is an operation that is a target for determining whether or not the miss operation determination unit 23 is a miss operation. The “arbitrary operation” is an operation related to display of new content data, update of content data, and the like. Specifically, in the example illustrated in FIG. 2, the “arbitrary operation” is a click on the first link L <b> 1 to the third link L <b> 3 of the content display unit 101. The “predetermined user operation” is an operation performed by the user with the intention of canceling the previous operation. The “predetermined user operation” is, for example, an operation such as clicking the “return” button, scrolling up or down the scroll bar.

  In the first embodiment, the miss operation determination unit 23 continuously repeats the operation of the user clicking the hyperlink and the operation of pressing the “return” button M times within a predetermined time N seconds. If this happens, the operation of clicking this hyperlink is determined to be a miss operation. Here, N seconds is a numerical value larger than 0 such as “5 seconds”, for example, and is data held in advance by the error operation determination unit 23. M times is a numerical value of a natural number such as “2 times”, for example, and is data held in advance by the miss operation determination means 23. For example, when an operation of “clicking on the A test in the first row” and an operation of pressing the “return” button are performed twice within 5 seconds, the miss operation determination means 23 determines the “A test It is determined that “click” is a mistake operation. Here, it may be mentioned as one of the requirements for determining that it is a mistake operation that other operations such as scrolling and clicking on another hyperlink are not sandwiched between repeated operations.

  As described above, when it is determined that a miss operation has occurred, the miss operation determination unit 23 stores the data of “A test on the first row” in the storage device 10 as the miss operation data 12 as an identifier of the miss operation.

  With reference to FIG. 6, the mistake operation determination process by the mistake operation determination means 23 which concerns on 1st Embodiment is demonstrated.

  First, in step S51, the miss operation determination unit 23 determines whether or not the latest operation content data is a press of a “return” button. When it is not a return button, it progresses to step S55 and the mistake operation determination means 23 determines with the last operation not being a mistake operation.

  When the latest operation content data is the “return” button, in step S52, the miss operation determination unit 23 determines whether or not the operation immediately before pressing the “return” button is an error operation from the operation record of the operation record data 11. Determine whether. In step S52, the miss operation determination unit 23 determines whether the same operation as that immediately before the “return” button is pressed and whether the “return” button is pressed M times within N seconds. When M times are not continued within N seconds, the process proceeds to step S55, and the miss operation determination unit 23 determines that the immediately preceding operation is not a miss operation.

  On the other hand, in the case where M operations are continued M times within N seconds without interposing another operation, in step S53, the miss operation determination unit 23 determines that the immediately preceding operation is a miss operation. In step S54, the miss operation determination unit 23 stores the identifier of the immediately preceding operation in the storage device 10 as the miss operation data 12.

  When the mistake operation determination unit 23 according to the first embodiment repeats the operation of clicking the hyperlink and the operation of pressing the “return” button continuously M times within a predetermined time N seconds, The operation of clicking this hyperlink is determined as a miss operation. Here, N = 5 and M = 2. In the example shown in FIG. 5D, the operation of “clicking A test” and the operation of clicking the return button are repeated twice within 5 seconds. Accordingly, the miss operation determination unit 23 determines that the operation of “click A test”, which is the process immediately before pressing the “return” button, is a miss operation, and updates the miss operation data 12.

  The content acquisition unit 24 acquires content data requested by a user operation and inputs the content data to the content output unit 26 when the mistake operation determination unit 23 does not determine that the operation is a mistake. The content acquisition unit 24 acquires content data requested by the user from the content providing device 2 via the communication control device 50 and stores it in the content storage data 13 as a cache. Here, when content data is requested by a user operation, the content acquisition unit 24 first searches the content storage data 13 and may request the content data from the content providing apparatus 2 if it is not stored in the cache. .

  The content modification unit 25 generates modified content data 14 by modifying the content data so that the operation target other than the operation target of the mistake operation is easily operated, and stores the modified content data 14 in the storage device 10. In particular, the content modification unit 25 according to the first embodiment generates the modified content data 14 so that the operation target of the mistake operation cannot be operated. The content modification unit 25 generates the modified content data 14 by deleting the hyperlink that is the target of the mistake operation or invalidating the button.

  The content data before modification and the modified content data 14 will be described with reference to FIG. FIG. 7A shows a part of the content data before modification, which is content data for displaying the screen of FIG. FIG. 7B is a part of the modified content data 14 and is content data for displaying the screen of FIG.

  In FIG. 7A, a hyperlink tag <a href="Atest.html"> and a corresponding tag </a> are provided in the display of “A test”. A hyperlink tag <a href="Btest.html"> and a corresponding tag </a> are provided in the display of “B test”. In the display of “C test”, a hyperlink tag <a href="Ctest.html"> and a corresponding tag </a> are provided. The information processing apparatus 1 displays the screen shown in FIG. 2 on the output device 60 using the content data before modification.

  On the other hand, in FIG. 7B, hyperlinks are provided for “B test” and “C test”, respectively. However, the hyperlink tag <a href="Atest.html"> and the corresponding tag </a> provided in “A test” have been deleted. In this way, the content modifying means 25 disables the click on the “A test” to be operated, so that the hyperlink tag <a href="Atest.html"> and the corresponding tag </a> Is deleted, and the modified content data 14 is generated.

  With reference to FIG. 8, the process of the content modification means 25 is demonstrated. First, in step S <b> 101, the content modification unit 25 acquires content data in which an error operation has occurred from the content accumulation data 13. The content modifying means 25 refers to the operation record data 11 and reads a record determined to be a mistake operation, and acquires data in the “URL where the operation occurred” column of the read record. In the example shown in FIG. 5D, since “click A test” is a mistake operation, the content modification means 25 uses “http://www.example.net/index. Get html ”. Further, the content modifying means 25 acquires content data corresponding to this “http://www.example.net/index.html” from the content accumulation data 13.

  In step S102, the content modifying unit 25 modifies the content data acquired in step S101 by deleting the link to be operated on by mistake. As shown in FIGS. 7A and 7B, the content modifying means 25 uses the hyperlink tag <a href = "Atest. Delete html "> and the corresponding tag </a>.

  In step S <b> 103, the content modifying unit 25 stores the data after deleting the hyperlink tag in step S <b> 102 in the storage device 10 as modified content data 14.

  In the embodiment of the present invention, the case where web content source data is modified and modified content data is output will be described. However, the present invention is not limited to this method. For example, the content modification unit 25 may modify the content data by a method other than the change of the HTML source code, such as a change of CSS (Cascading Style Sheets).

  The content output means 26 outputs content data to the output device 60 based on a user operation. When the content data is expressed in HTML or the like, the content output means 26 renders the content data and outputs it to the output device 60 in a format that can be viewed by the user.

  Here, the content output device 60 outputs the modified content data 14 generated by the content modification means 25 to the output device 60 when a mistake operation is determined. On the other hand, when the mistake operation is not determined, the content data acquired by the content acquisition unit 24 according to the user operation, specifically, the content data that has not been modified is output to the output device 60. When the function switching button B102 is pressed after outputting the modified content data 14, the content output device 60 outputs the content data in which the modification of the modified content data 14 is eliminated to the output device 60.

  As described above, the information processing apparatus 1 according to the first embodiment of the present invention modifies and displays the content data so that it cannot be operated on the operation target of the mistake operation. Thereby, it can avoid that a user repeats the same mistake operation.

  In the example illustrated in FIG. 2, the hyperlink “A test” is not a link intended by the user, but a hyperlink in the vicinity thereof is considered to be a link intended by the user. When the user operates the link intended by the user, the user may accidentally operate “A test” again. According to the information processing apparatus 1 according to the first exemplary embodiment of the present invention, even if the user erroneously selects “A test” again, the hyperlink is deleted, so the screen is changed to any screen by the operation. Does not occur. Therefore, the user can easily perform an intended operation on the screen shown in FIG.

  As described above, the information processing apparatus 1 according to the embodiment of the present invention detects a user's erroneous operation and modifies the display of the screen on which the erroneous operation has occurred. Thereby, the information processing apparatus 1 can reduce the occurrence rate of the problem that the user repeats an erroneous operation.

(Second Embodiment)
The second embodiment differs from the first embodiment in the processing of the content modification means 25. In the first embodiment, the content modification unit 25 modifies the content data so that it cannot be operated on the operation target of the mistake operation. On the other hand, in the second embodiment, the content modification unit 25 modifies the modified content data so that the display position of the operation target of the mistake operation is separated from the display position of the operation target in the vicinity of the operation target determined to be the mistake operation. 14 is generated. In the second embodiment, in particular, the modified content that changes the display position of the operation target determined to be the miss operation so that the operation target determined to be the miss operation is displayed at a position away from the nearby operation target. Data 14 is generated.

  For example, consider the case where the user operates “A test” on the screen shown in FIG. When the user's “A test” operation is determined to be an error operation by the error operation determination unit 23, the information processing apparatus 1 displays the screen shown in FIG. The content display unit 103 of the screen illustrated in FIG. 9 provides the first link L1 in the “A test” that is the operation target of the mistake operation, as in FIG. However, the display position of “A test” is right-justified in FIG. 2, whereas the display position of “B test” is left-justified.

  With reference to FIG. 10, the content modification process by the content modification unit 25 according to the second embodiment will be described. First, in step S <b> 201, the content modification unit 25 acquires content data in which an error operation has occurred from the content accumulation data 13. The content modifying means 25 refers to the operation record data 11 and reads a record determined to be a mistake operation, and acquires data in the “URL where the operation occurred” column of the read record.

  In step S202, the content modification unit 25 modifies the content data acquired in step S201 by moving the link that is the target of the mistake operation to a position away from the nearby operation target.

  In step S203, the content modification unit 25 stores the data after the link is moved in step S202 in the storage device 10 as the modified content data 14.

  The content modification unit 25 according to the second embodiment, when a mistake operation is determined, calculates the coordinates of each operation target when output to the output device 60 based on the content data in which the mistake operation has occurred. To do. Furthermore, the content modification unit 25 identifies an operation target in the vicinity of the operation target of the mistake operation. The content modification means 25 modifies the content data so that the operation target that is the target of the mistake operation is displayed at a position away from the nearby operation target.

  Here, there are various methods for modifying the display so as to display the mistake operation target at a position away from the nearby operation target. For example, in the example illustrated in FIG. 2, the first link L <b> 1 that is the operation target of the mistake operation is located on the right side of the content display unit 101. In addition, the second link L2 and the third link L3 are located in the vicinity of the first link L1 to be operated by the mistake operation. Therefore, the content modifying unit 25 modifies the content data so that the first link L1 is displayed in the opposite direction to the nearby links. Specifically, as shown in FIG. 11, the content modification unit 25 converts <a href="Atest.html"> A test </a> corresponding to the first link L1 to <div align = "left Enclosed by “> and </ div>, the modified content data 14 is generated. As shown in FIG. 9, the information processing apparatus 1 displays the first link L1 on the left side and displays it at a position away from the second link L2 and the third link L3, as shown in FIG. can do. The position where the operation target of the miss operation moves may be arbitrarily determined.

  In the second embodiment, a case where web content source data is modified and the modified content data 14 is output will be described. However, the present invention is not limited to this method. For example, in the second embodiment, as in the first embodiment, the content modification unit 25 may modify the content data by a method other than the change in the HTML source code, such as a change in CSS. good.

  As described above, the information processing apparatus 1 according to the second embodiment of the present invention modifies and displays the content data so that the operation target of the mistake operation is displayed at a position away from the nearby operation target. Thereby, it can avoid that a user repeats the same mistake operation.

  In the example illustrated in FIG. 2, the hyperlink “A test” is not a link intended by the user, but an operation target in the vicinity thereof is considered to be a link intended by the user. According to the information processing apparatus 1 according to the second embodiment of the present invention, when the link intended by the user is operated again, the “A test” that was erroneously operated last time is at a position away from the intended operation target. Since it is displayed, the intended operation can be facilitated.

(Third embodiment)
The third embodiment differs from the first embodiment in the processing of the content modification means 25. In the first embodiment, the content modification unit 25 modifies the content data so that it cannot be operated on the operation target of the mistake operation. On the other hand, in the third embodiment, the content modification unit 25 is configured so that the display area of the operation target of the mistake operation is smaller than the display area of the operation target in the vicinity of the operation target determined to be the miss operation. The modified content data 14 is generated. In the third embodiment, in particular, the modified content data that reduces the display area of the operation target determined to be an error operation so that the operation target determined to be an error operation is smaller than the display area of the nearby operation target. 14 is generated.

  For example, consider the case where the user operates “A test” on the screen shown in FIG. When the user's “A test” operation is determined to be an error operation by the error operation determination means 23, the information processing apparatus 1 displays the screen shown in FIG. The content display unit 104 of the screen shown in FIG. 12 provides the first link L1 in the “A test” that is the operation target of the mistake operation, as in FIG. However, the display area of “A test” shown in FIG. 12 is smaller than the display areas of “B test” and “C test”.

  The content modification unit 25 changes the operation target display area of the miss operation so that the display area of the operation target of the miss operation is smaller than the display area of the operation target of the miss operation when the miss operation occurs. Then, it can be considered that the modified content data 14 is generated. For example, when the user operates “A test” on the screen shown in FIG. 2 and this operation is determined to be a mistake operation, the information processing apparatus 1 displays the screen shown in FIG. The display area of “A test” shown in FIG. 12 is smaller than the display area of “A test” shown in FIG.

  With reference to FIG. 13, the content modification process by the content modification unit 25 according to the third embodiment will be described. First, in step S <b> 301, the content modification unit 25 acquires content data in which an error operation has occurred from the content accumulation data 13. The content modifying means 25 refers to the operation record data 11 and reads the record of the operation determined to be a miss operation, and acquires the data in the “URL where the operation occurred” column of the read record.

  In step S302, the content modification unit 25 modifies the content data acquired in step S301 so as to reduce the mistake operation target.

  In step S <b> 303, the content modification unit 25 stores the data that has been reduced in step S <b> 302 in the storage device 10 as modified content data 14.

  Here, there are various methods for modifying the mistake operation target so as to be displayed small. For example, in the example shown in FIG. 2, the first link L1 that is the target of the mistake operation is displayed in the same character size as the second link L2 and the third link L3 in the vicinity thereof. Therefore, the content modifying unit 25 modifies the content data so that the first link L1 is displayed small. Specifically, as shown in FIG. 14, the content modifying unit 25 performs <a href="Atest.html"> A test </a> corresponding to the first link L1 with <font size = "1 The modified content data 14 is generated by enclosing it with “>” and “</ font>”. As shown in FIG. 12, the information processing apparatus 1 displays the first link L1 in a small size, and the second link L2 and the third link L3 as the first link L1. It can be displayed relatively larger. The size of the operation target of the miss operation may be arbitrarily determined.

  In the third embodiment, a case where web content source data is modified and modified content data is output will be described. However, the present invention is not limited to this method. For example, also in the third embodiment, as in the first embodiment, the content modifying unit 25 modifies the content data by a method other than the change of the HTML source code, such as a change of CSS. good.

  As described above, the information processing apparatus 1 according to the third embodiment of the present invention modifies and displays the content data so that the operation target of the mistake operation is displayed small. Thereby, it can avoid that a user repeats the same mistake operation.

  In the example illustrated in FIG. 2, the hyperlink “A test” is not a link intended by the user, but a hyperlink in the vicinity thereof is considered to be a link intended by the user. When the user operates the link intended by the user, the user may accidentally operate “A test” again. According to the information processing apparatus 1 according to the third embodiment of the present invention, since the display of “A test” is smaller than that in FIG. 2, the possibility of selecting the operation target of “A test” Becomes lower. In the screen shown in FIG. 12, the nearby operation target is displayed relatively large, so that the user can easily operate the operation target intended by the user.

(Fourth embodiment)
The fourth embodiment differs from the first to third embodiments in the object to be modified. The information processing apparatus 1 according to the first to third embodiments has modified the content data so that it becomes difficult to operate the operation target of the mistake operation. On the other hand, the information processing apparatus 1 according to the fourth embodiment modifies the operation target in the vicinity of the operation target of the mistake operation.

  A mistake operation occurs when an intended operation target is operated and the operation is performed erroneously. Therefore, the information processing apparatus 1 according to the fourth embodiment specifies a candidate for an operation target intended by the user from the operation targets for the miss operation. Furthermore, the information processing apparatus 1 modifies the content data so that the specified operation target candidate can be easily operated.

  For example, consider the case where the user operates “A test” on the screen shown in FIG. When the user's “A test” operation is determined to be a mistake operation by the mistake operation determination unit 23, the information processing apparatus 1 performs the “B test” of the second link L2 near the operation target of the “A test”. "Is a candidate for an operation target. In this case, the information processing apparatus 1 displays the screen shown in FIG. The content display unit 105 of the screen shown in FIG. 15 displays the “A test” that is the operation target of the mistake operation in the same size as the screen shown in FIG. However, the content display unit 105 in FIG. 15 displays the “B test” that is the operation target candidate larger than the other operation targets “A test” and “C test” shown in FIG.

  The content modification means 25 is configured such that the display area of the operation target (operation target candidate) in the vicinity of the operation target determined to be an error operation is larger than the display area of the operation target candidate when the error operation occurs. It is also conceivable to generate the modified content data 14 by changing the display area of the candidate operation target. For example, if the user operates “A test” on the screen shown in FIG. 2 and this operation is determined to be a mistake operation, the information processing apparatus 1 uses the second link in the vicinity of the operation target of “A test”. The “B test” of L2 is set as an operation target candidate. In this case, the information processing apparatus 1 displays the screen shown in FIG. The display area of “B test” shown in FIG. 15 is larger than the display area of “B test” shown in FIG.

  In the example illustrated in FIG. 15, the operation target candidate is only the second link L2 of “B test”, but is not limited to this example. The information processing apparatus 1 may also output the third link L3 of “C test” as an operation target candidate.

  With reference to FIG. 16, an information processing apparatus 1 according to the fourth embodiment will be described. The information processing apparatus 1 according to the fourth exemplary embodiment is different from FIG. 1 in that the operation candidate specifying unit 27 is provided.

  The operation candidate specifying unit 27 specifies an operation target candidate that may be an operation target that the user originally intended to operate when the user makes a mistake. The operation target candidate is a modification target when the content modification unit 25 generates modified content data.

  When a mistake operation is determined, the operation candidate specifying unit 27 calculates the coordinates of each operation target when output to the output device 60 based on the content data in which the mistake operation has occurred. Furthermore, the content modification unit 25 specifies an operation target in the vicinity of the operation target of the mistake operation as an operation target candidate.

  The content modifying unit 25 modifies the display area of the operation target candidate specified by the operation candidate specifying unit 27 to generate the modified content data 14. Particularly in the fourth embodiment, the modified content data is generated by modifying the candidate operation target to be large.

  With reference to FIG. 17, the content modification process by the content modification unit 25 according to the fourth embodiment will be described. First, in step S <b> 401, the content modification unit 25 acquires content data in which an error operation has occurred from the content accumulation data 13. The content modifying means 25 refers to the operation record data 11 and reads a record determined to be a mistake operation, and acquires data in the “URL where the operation occurred” column of the read record.

  In step S402, the operation candidate specifying unit 27 calculates the coordinate position of each operation target when the content data is output to the output device 60. Further, in step S403, the operation candidate specifying unit 27 specifies an operation target within a predetermined distance R from the coordinates of the operation target of the miss operation as an operation target candidate. Here, the distance R is a numerical value larger than 0 such as “5 mm”, for example, and is data stored in advance by the operation candidate specifying unit 27.

  In step S404, the content modifying unit 25 modifies the content data acquired in step S401 to increase the operation target candidate.

  In step S <b> 405, the content modifying unit 25 stores the data that has been increased in step S <b> 404 in the storage device 10 as modified content data 14.

  The operation candidate specifying unit 27 can appropriately determine the operation target candidate by appropriately changing the distance R when determining the operation target candidate. For example, R may be set large for people who have many errors in input operations or for elderly people.

  Here, there are various methods for modifying the neighboring operation target candidates so as to be displayed larger. For example, in the example illustrated in FIG. 2, the second link L2 is displayed in the vicinity of the first link L1 that is the operation target of the miss operation, and thus the second link L2 is an operation target candidate. Therefore, the content modifying unit 25 modifies the content data so that the second link L2 is displayed large. Specifically, as shown in FIG. 18, the content modifying means 25 performs <a href="Btest.html"> B test </a> corresponding to the second link L2 with <font size = "5 The modified content data 14 is generated by enclosing it with “>” and “</ font>”. With such modified content data 14, the information processing apparatus 1 can display a large second link L2 in the vicinity of the first link L1 subject to the error operation, as shown in FIG. The size of the operation target candidate may be arbitrarily determined.

  In the fourth embodiment, a case where web content source data is modified and modified content data is output will be described. However, the present invention is not limited to this method. For example, also in the fourth embodiment, as in the first embodiment, the content modification means 25 may modify the content data by a method other than the change of the HTML source code, such as a change of CSS. good.

  In the fourth embodiment, a case has been described in which, when a miss operation occurs, the coordinates of the operation target of the content data in which the miss operation has occurred are calculated, but the present invention is not limited to this. For example, when the operation recording unit 22 updates the operation record data 11, the coordinates of each operation target may be calculated and recorded in the operation record data 11 in association with each operation. In that case, the operation record data 11 has an item of coordinates as shown in FIG. When the operation acquisition unit 21 acquires the coordinates specified by the user with the input device 40 from the input device 40, the operation recording unit 22 sets the coordinates specified by the user acquired from the input device 40 in the operation record data 11. May be set.

  As described above, the information processing apparatus 1 according to the fourth exemplary embodiment of the present invention modifies and displays content data so as to display a large candidate for an operation target intended by the user. Thereby, it can avoid that a user repeats the same mistake operation.

  In the example illustrated in FIG. 2, the hyperlink “A test” is not a link intended by the user, but a hyperlink in the vicinity thereof is considered to be a link intended by the user. When the user operates the link intended by the user, the user may accidentally operate “A test” again. According to the information processing apparatus 1 according to the fourth embodiment of the present invention, the display of “B test” in the vicinity of “A test” is larger than that in FIG. It becomes easy to select the operation target. In the screen shown in FIG. 15, the operation target candidates are displayed in a large size, so that the user can easily operate the link intended by the user.

(Fifth embodiment)
The information processing apparatus 1 according to the fifth embodiment is different from the fourth embodiment in a method for specifying an operation target candidate. In the fourth embodiment, the operation target in the vicinity of the operation target that has been mistakenly operated is specified as the operation target candidate. On the other hand, in the information processing apparatus 1 according to the fifth embodiment, the input device 40 is assumed to be a touch panel, for example. The information processing apparatus 1 according to the fifth embodiment specifies the operation target touched by the user's finger in addition to the operation target of the mistake operation as the operation target candidate intended by the user when the mistake operation occurs. To do.

  Compared with the information processing apparatus 1 according to the fourth embodiment described with reference to FIG. 16, the information processing apparatus 1 according to the fifth embodiment has a data structure of the input device 40 and the operation record data 11, The processing of the operation acquisition unit 21 and the operation candidate specifying unit 27 is different.

  The input device 40 according to the fifth embodiment is a device that can select a plurality of operation targets by a single operation of the user, and is, for example, a touch panel. When the user operates the touch panel with a finger, the user may touch a plurality of operation targets. When the user operates on a plurality of operation targets, the input device 40 recognizes the operation target with the highest detection level as the operation target operated by the user. In addition, the input device 40 recognizes the other operation target as an operation target only touched by the user. The input device 40 inputs the operation target identifier recognized as operated by the user and the operation target identifier just touched to the operation acquisition unit 21 via the input / output interface 30. When the user touches only one operation target, the input device 40 inputs only the operation target identifier to the operation acquisition unit 21.

  The operation acquisition unit 21 acquires information on the identifier of the operation target and the identifier of the operation target just touched from the input device 40.

  The operation recording unit 22 stores the operation target identifier acquired by the operation acquisition unit 21, the operation target identifier just touched, and the time in the operation record data 11.

  The operation record data 11 is operation log data as shown in FIGS. 20 and 21, for example. The operation recording unit 22 generates a record associating the URL of the operation, the operation data of the user, and the data of each item of time each time the user operates. The operation recording unit 22 inserts the generated record into the operation record data 11.

  The operation record data 11 according to the fifth embodiment includes an item “operation object touched by a finger” as compared with the operation record data according to the first embodiment described with reference to FIG. 5. Is different. The “URL where the operation has occurred” item, the “user operation data” item, and the “time” item are the same as those in FIG.

  The operation recording unit 22 sets the identifier of the operation target input from the input device 40 in the “user operation data” item. Further, the operation recording unit 22 sets the identifier of the operation target just touched, which is input from the input device 40, in the item “operation target touched by the finger”.

  Each of the data shown in FIGS. 20A to 20C and FIG. 21 corresponds to the data shown in FIGS. 5A to 5D. In the “operation object touched by finger” field, an identifier of the operation object just touched, which is input from the input device 40 during each operation, is set. The operation target touched by the finger may be set with a plurality of operation target identifiers, or may not be set with a single operation target identifier.

  Based on the user operation data in the operation record data 11, the miss operation determination unit 23 determines whether or not a miss operation has occurred based on whether or not a predetermined user operation has occurred within a predetermined time. Further, the error operation determination means 23 performs an error operation depending on whether the operation target identifier is included in the item “operation target touched by a finger” or the number of operation target identifiers included. It may be determined whether or not there is.

  The operation candidate specifying unit 27 specifies an operation target touched by a finger as an operation target intended by the user when a mistake operation occurs. The operation candidate specifying unit 27 reads the operation record data 11 and the miss operation data 12 from the storage device 10. The operation candidate specifying unit 27 acquires the operation target identifier of the miss operation from the miss operation data 12, and acquires from the operation record data 11 the record that executed the operation target of the miss operation. The operation candidate specifying unit 27 outputs the identifier of the operation target set in the item “operation target touched by a finger” of the acquired record as an operation target candidate.

  Here, when a specific operation is repeated, the miss operation determination unit 23 identifies the repeated operation as a miss operation. Therefore, the operation record data 11 may include a plurality of records related to the operation target of the mistake operation. In this case, the operation candidate specifying unit 27 may use, as the operation target candidate, the identifier of the operation target set in each item of “the operation target touched by the finger” of the plurality of records. For example, the operation candidate specifying unit 27 may set an operation target touched by a finger on all records as an operation target candidate, or set an operation target touched by a finger on a predetermined number or more records as an operation target candidate. Also good.

  The content modifying unit 25 modifies the operation target candidate specified by the operation candidate specifying unit 27 to generate the modified content data 14. The content modification unit 25 changes the display position of the operation target candidate so as to increase the operation target candidate or to increase the distance from the operation target of the mistake operation. In addition, the content modification unit 25 may change the display position of the operation target candidate so as to increase the display area of the operation target candidate and increase the distance from the operation target of the mistake operation.

  With reference to FIG. 22, the process of the content modification means 25 which concerns on 5th Embodiment is demonstrated. First, in step S <b> 501, the content modification unit 25 acquires content data in which an error operation has occurred from the content accumulation data 13. The content modifying means 25 refers to the operation record data 11 and reads a record determined to be a mistake operation, and acquires data in the “URL where the operation occurred” column of the read record.

  In step S <b> 402, the operation candidate specifying unit 27 specifies an operation target touched by a finger when an error operation occurs, which is specified by the item “operation target touched by a finger”, as an operation target candidate.

  In at least one of steps S503 and S503a, the content modifying unit 25 modifies the operation target candidate for the content data acquired in step S501. Specifically, the content modification unit 25 increases the operation target candidate or increases the distance from another operation target.

  In step S504, the content modification unit 25 stores the data modified in step S503 in the storage device 10 as modified content data 14.

  With reference to FIG. 23, the screen which the information processing apparatus 1 which concerns on 5th Embodiment outputs is demonstrated. 23, in the screen shown in FIG. 2, the operation of the first link L1 of “Test A” by the user is determined to be a mistake operation. , The modified web page when the third link L3 of “Test C” is touched. In the example illustrated in FIG. 23, the content display unit 106 displays the second link L2 and the third link L3 that have been touched by the finger at a position away from the first link L1 that is the operation target of the mistake operation.

  Since the content modification means 25 displays the second link L2 and the third link L3 as the operation target candidates at positions separated from the first link L1 as the operation target of the mistake operation, the content modification unit 25 is illustrated in FIG. The content data is modified to the content data shown in FIG.

  As shown in FIG. 24, the content modifying unit 25 inserts </br> </br> before each of the operation target candidates “B test” and “C test”, and performs “B test” and “C test”. A line break is intentionally placed before “test”. Thereby, the information processing apparatus 1 can display the operation target candidate at a position away from the mistake operation target candidate.

  Further, as shown in FIG. 25, the content modification unit 25 may generate the modified content data 14 so that the operation target candidates “B test” and “C test” are displayed large. As shown in FIG. 26, the content modifying means 25 displays the modified content so that the operation target candidates “B test” and “C test” are displayed large and apart from the operation target “A test” of the mistake operation. Data 14 may be generated.

  As described above, the information processing apparatus 1 according to the fifth embodiment specifies the operation target actually touched as an operation target candidate when an error operation occurs, so that the operation target candidate can be easily operated. Modify content data. This makes it easier for the user to operate with the modified content data even if the user cannot operate it.

(Sixth embodiment)
The sixth embodiment differs from the first to fifth embodiments in the processing of the error operation determination unit 23. In the first to fifth embodiments, as described with reference to FIG. 6, the error operation determination means, when the “return” button is operated based on the operation record data 11, A miss operation is determined with reference to the past operation record. The miss operation determination means determines that a miss operation has occurred when an arbitrary operation and a predetermined operation are repeated a predetermined number of times within a predetermined time. This predetermined operation is, for example, pressing of a “return” button or each of the scroll bar up scroll and down scroll operations. Further, the miss operation determination unit 23 may determine that a miss operation has occurred when the up scroll and the down scroll are repeated a predetermined number of times as a series of operations.

  For example, the operation record data 11 shown in FIG. 27 will be described. The operation record data 11 shown in FIG. 26 indicates that, as a predetermined operation, when the successive operations of “up scroll” and “down scroll” of the browser are repeated three times within 3 seconds, the operation immediately before that is missed. It is an example to determine. In the example shown in FIG. 27, after the operation of “click <a href="Atest.html"> A test </a> on the first line" occurs, the browser “up scroll” and “ The continuous operation of “down scroll” is repeated three times. Accordingly, the miss operation determination unit 23 determines that the operation of “click on the first line <a href="Atest.html"> A test </a>" is a miss operation.

  With reference to FIG. 28, the process of the mistake operation determination means 23 which concerns on 6th Embodiment is demonstrated. First, in step S61, when the miss operation determination unit 23 detects that an arbitrary operation has occurred, in step S62, the miss operation determination unit 23 measures the time since the occurrence of the arbitrary operation in step S61. Next, when a new operation is recorded in the operation record data 11, in step S63, the miss operation determination means 23 determines whether or not the operation has occurred within a predetermined time (N seconds) from the arbitrary operation in step S61. Determine whether. If N seconds have elapsed, the process proceeds to step S67, and it is determined that the arbitrary operation detected in step S61 is not a mistake operation.

  On the other hand, when a new operation is input within the predetermined time in step S63, the process proceeds to step S64. In step S <b> 64, the miss operation determination unit 23 determines whether or not the new operation is a predetermined operation such as pressing of the “return” button or the scroll bar up scroll and down scroll operations. If it is not a predetermined operation, the miss operation determination means 23 returns to step S63 and waits for a new operation to be input.

  On the other hand, when the new operation is a predetermined operation in step S64, in step S65, the miss operation determination unit 23 determines that the operation generated in step S61 is a miss operation. In this case, the miss operation determination unit 23 updates the miss operation data 12 in step S66.

In the embodiment of the present invention, when a predetermined user operation occurs within a predetermined time from an arbitrary user operation, the erroneous operation determination unit 23 determines that the arbitrary user operation is a misoperation. Various methods are conceivable as the error operation determining means 23 for determining the error operation, as shown in the first embodiment and the sixth embodiment, as described above. Although described according to the first embodiment to the sixth embodiment, it should not be understood that the description and drawings constituting a part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples, and operational techniques will be apparent to those skilled in the art.

  For example, the examples described in the first embodiment to the sixth embodiment may be appropriately combined and implemented. For example, the information processing apparatus 1 has a display area that is smaller than an operation target display area in the vicinity of the operation target that is determined to be the erroneous operation, and the display position is the vicinity of the operation target of the mistake operation. The screen may be displayed so as to be away from the display position of the operation target. In this case, the content modification unit 25 generates the modified content data 14 so that the operation target determined to be a mistake operation has a display area smaller than that of a nearby operation target and is displayed at a distant position.

  It goes without saying that the present invention includes various embodiments not described herein. Therefore, the technical scope of the present invention is defined only by the invention specifying matters according to the scope of claims reasonable from the above description.
