Description

  The present invention relates to a technology for changing a UI (User Interface) using information on skills estimated based on a user operation log.

  2. Description of the Related Art Conventionally, when information such as Web contents is provided to a user via a network, a technology has been proposed in which information is adjusted and provided in an optimal form in response to various requests with various user characteristics ( For example, see Patent Document 1). As described above, when providing information such as Web content, it is required to present a UI according to various user characteristics, and for that purpose, a technology for automatically estimating the user characteristics is required. is there.

  In particular, estimating the skill of the user, which is one of the characteristics of the user, such as how much the user can use ICT (Information and Communication Technology) devices such as PCs, smartphones, and tablets, is based on the presentation of UI according to the characteristics of the user. It is important in doing.

  Conventionally, an index of a skill of how well a user can use an ICT device has been calculated based on data such as the time required for a certain user to achieve a specific task and the number of mistakes. Therefore, estimating the skills, that is, estimating the achievement rate and achievement time of the task.

JP 2005-056151 A

  However, even if the achievement rate and achievement time of the task can be estimated, it is difficult to change the UI appropriately. This is because it is not known what causes the user's trip.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the embodiments described below are merely examples, and the embodiments to which the present invention is applied are not limited to the following embodiments.

(Outline of Embodiment)
For a user to master ICT equipment, for example, the following skills are required.

(1) Positive attitude toward the Internet
(2) Internet experience
(3) Ability to grasp the current location in a system such as a website with a hierarchical structure
(4) Visual search ability to quickly and accurately find the desired information from the information displayed on the screen
(5) Working memory that can temporarily hold targets and displayed information
(6) Exercise Ability to Move the Body Quickly and Accurately In the present embodiment, the skill estimating device estimates each of the above skill levels and presents a UI according to the skill levels. Hereinafter, the contents of the present embodiment will be described in detail.

  In the present embodiment, a user whose skill is to be estimated operates a ICT device having a touch panel (eg, a smartphone, a tablet, etc.) to browse and operate Web contents (Web pages) provided from the Internet. Is assumed, but this is only an example. Devices operated by the user are not limited to ICT devices. The device operated by the user may not be a device having a touch panel. In addition, the target that the user browses is not limited to Web content.

(Device configuration)
FIG. 1 is a configuration diagram of a skill estimation device 100 according to the present embodiment. The skill estimation device 100 is a device that quantitatively and objectively evaluates how much the user has the ICT use skill, and changes the UI accordingly.

  The skill estimation device 100 may be a terminal used by a user for browsing information, or may be a device different from the terminal. In the present embodiment, the skill estimation device 100 It is assumed that the device is different from a terminal used for a user to browse information. The skill estimating apparatus 100 of the present embodiment is, for example, a server provided on a network, and obtains operation logs and the like from a terminal operated by a user via a network to obtain skill estimation, UI change information acquisition, UI Make changes, etc.

  When the skill estimation device 100 is a terminal used by a user to browse information, an operation log acquired by the terminal (skill estimation device 100) is internally transferred to a functional unit corresponding to the skill estimation device 100. Then, skill estimation, UI change information acquisition, UI change, and the like are performed.

  As shown in FIG. 1, the skill estimation device 100 includes a log input unit 101, a log processing unit 102, a log storage unit 103, a skill estimation unit 104, a model storage unit 105, a skill output unit 106, a skill storage unit 107, and a UI processing unit. 108, a UI storage unit 109, and a UI change unit 110. The operation of each unit will be described later. Note that each storage unit illustrated in FIG. 1 may be provided inside the skill estimation device 100 or may be provided on a server such as a database server connected to a network.

  Further, since the skill estimation device 100 is a device that changes the UI, it may be referred to as a user interface change device. Also, since the skill estimation device 100 can output information for changing the UI, this may be referred to as a user interface information providing device. Further, the skill estimation device 100 may not include the UI changing unit 110. In this case, the skill estimation device 100 outputs information for changing the UI to the outside, and the external device or the like performs the same processing as the UI changing unit 110.

  The skill estimation device 100 according to the present embodiment includes, for example, a general-purpose computer system including a CPU, a memory, an external storage device such as an HDD, an input device, and an output device (eg, a smartphone, a tablet, PC etc.) can be used. In this computer system, each function of the skill estimating apparatus 100 is realized by the CPU executing the program loaded on the memory. In addition, the program of the skill estimation device 100 can be stored in a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD-ROM, or can be distributed via a network.

(Operation of the skill estimation device 100)
Hereinafter, an operation example of the skill estimation device 100 will be described in detail with reference to flowcharts and the like.

  FIG. 2 is a flowchart showing the overall operation of skill estimation apparatus 100 when skill estimation apparatus 100 estimates the skill of the user and changes the UI based on the estimated skill.

  In step S1, the user starts an operation log collection program in a terminal that holds the user in order to estimate a skill. For example, a program is launched as a browser application of a terminal (eg, a smartphone, a tablet, or the like). At this time, a sensor input provided in the terminal such as a touch sensor of a touch panel is turned on.

  The operation log collection program is a program having a function of collecting operation logs in a terminal used by the user and passing the operation logs to the skill estimation device 100.

  In step S2, a user ID is input to the skill estimation device 100. The user ID input here is, for example, a user account at the time of terminal login, but may be any ID that can identify a user.

  In step S3, the skill estimating unit 104 or the skill output unit 106 refers to the skill storage unit 107 based on the user ID, and determines whether the skill level of the user already exists. If the user already exists, the process proceeds to step S4, in which the skill output unit 106 acquires the skill level of the user from the skill storage unit 107, outputs the acquired skill level to the UI processing unit 108, and proceeds to step S14.

  If the skill level does not exist, the process proceeds to step S5, and the input of the operation log of the user is started. When the user performs an operation, information from a touch panel or a web page is input to the log input unit 101 of the skill estimation device 100. For example, from the touch panel, operation logs such as the touch intensity of the screen and the area of the touch are acquired by the terminal, and the operation logs are input to the log input unit 101.

  As information from the Web page, a history of page transitions and the like are input to the log input unit 101. The “information from the web page” is information on an operation on the web page and display of the web page.

  When the user finishes the operation log collection program on the terminal, or when the operation log acquisition time is longer than the minimum time (for example, 3 minutes or longer), the process proceeds to step S6. The minimum acquisition time may be any value.

  In step S6, for example, the log input unit 101 determines whether the acquisition time of the operation log is 3 minutes or more. If the acquisition time of the operation log is less than 3 minutes, the process proceeds to step S7, where the operation log is The process ends without recording. If the operation log acquisition time is 3 minutes or more, the process proceeds to step S8, where the operation log for 3 minutes is passed to the log processing unit 102 and is shaped. Note that “3 minutes” is merely an example, and a time length other than “3 minutes” may be used.

  The log processing unit 102 performs, for example, a process of calculating an average value of the touch intensity of the screen, a process of calculating the number of displayed pages from a history of page transition, and the like. FIGS. 3 and 4 show examples of the operation log list. FIG. 3 is an example of a list of operation logs that can be obtained from the touch panel, and FIG. 4 is an example of a list of operation logs that can be obtained from the Web page.

  In step S9 of FIG. 2, the log processing unit 102 records the shaped operation log with the ID in the log storage unit 103. FIG. 5 shows an example of the recorded operation log. Although only a part is shown in the example of FIG. 5, the values of all the operation logs shown in FIGS. 3 and 4 are recorded in the log storage unit 103 for each ID.

  In step S10 of FIG. 2, the shaped operation log is passed from the log processing unit 102 to the skill estimation unit 104.

  In step S11, the skill estimating unit 104 refers to the model storage unit 105 and reads models for estimating a plurality of skill levels from the operation log. For example, a model for estimating the skill level of each of attitude, experience, spatial grasping ability, visual search ability, working memory, and athletic ability is read. The “model” read by the skill estimating unit 104 specifically corresponds to a program for performing a process of estimating a skill level.

  In step S12, the skill estimating unit 104 estimates each skill level based on the read model. Details of the process of estimating each skill level will be described later.

  When the estimation in step S12 is completed, the process proceeds to step S13, and each skill level estimated by the skill estimating unit 104 is recorded in the skill storage unit 107. FIG. 6 shows an example of each skill level recorded in the skill storage unit 107. As shown in FIG. 6, the six skill levels described above are recorded for each ID. In the present embodiment, since each skill level is divided into two levels, 0 is recorded for a low skill and 1 is recorded for a high skill. Note that dividing the skill level into two stages is merely an example, and the skill level may be divided into, for example, three stages or four or more stages.

  In step S14, each skill level (skill level pattern) of the user is acquired by the skill output unit 106, and the skill level is passed from the skill output unit 106 to the UI processing unit 108. In step S15, the UI processing unit 108 reads information indicating a UI changing method corresponding to each skill level (pattern) recorded in the UI storage unit 109. As described later, the read UI change method information is passed from the UI processing unit 108 to the UI change unit 110, but the UI processing unit 108 may output the read UI change method information to the outside. Good.

  FIG. 7 shows an example of information indicating a UI change method recorded in the UI storage unit 109. The example illustrated in FIG. 7 illustrates patterns of six skill levels and a UI changing method corresponding to the patterns.

  The information (pattern) of “skill” in FIG. 7 indicates 0 = low, 1 = high in the order of (attitude, experience, spatial grasping ability, visual search ability, working memory, exercise ability). Also, the information on "UI change method" includes (eliminating technical terms, adding shortcut functions, reducing the level of hierarchy, reducing the amount of information per page, adding memo functions, increasing buttons, summarizing functions, 0 = no change, 1 = change is performed in the order of (insert transition animation).

  Note that the above “eliminating technical terms” is an example of information indicating a viewpoint of UI change, and also an example of association between a skill pattern and a UI change method pattern. Information of a change viewpoint other than the above may be used, and the association between the skill pattern and the UI change method pattern may be another association. In the present embodiment, the number of change viewpoints is eight in total, but the number is not limited to this. It may be less than eight or more than eight.

  However, when the athletic ability is low, a change of “insert a transition animation” is performed. FIG. 8 shows an image of the transition animation. In FIG. 8, when a button with a link set on a certain page is tapped (a), the transition source page is pushed up (b), and the transition destination page appears from below (c). Is shown. In the present embodiment, the type of animation is such that the page moves up and down, but may be an expression that zooms in and out or turns the page of the book. Further, an expression in which a blank page is inserted at the time of transition may be used. It is characterized in that the page is not instantaneously switched from the transition source to the transition destination page, but is switched after some kind of animation or another content is inserted in between.

  According to the research by the inventors, users with low athletic ability tend to tap buttons and links repeatedly because they can not accurately execute taps and clicks, so when a page transitions, the transition source page to the transition destination page Instantaneously, even if the page transition succeeds, the buttons and links located at the same position on the page after the transition are mistakenly pressed, and there is a problem that many transitions to the unintended page occur. know. Furthermore, it has been shown that inserting a transition animation is effective for this problem. Further, it is also shown that for a user having high athletic ability, processing takes time by the amount of the transition animation, and conversely, the satisfaction of the operation decreases. Therefore, in the present embodiment, a transition animation is inserted only when the athletic ability is low.

  When only the attitude is low and the other skills are high for a certain user, the first line in FIG. 7 is matched, and it is determined that the UI of the user is changed to eliminate technical terms. . In addition, when both the spatial grasping ability and the visual search ability are low, it matches the sixth line in FIG. In this case, the effect of the combination is to simply add the third and fourth lines in FIG. 7 and change the UI to make the hierarchy shallower and reduce the amount of information per page. It is decided to implement the UI change in consideration of. However, the method of changing the UI is not limited to this.

  Also, in the present embodiment, a case in which the UI is changed using the estimation results of all six skills will be described. However, the skill to be used is one of the six, or the estimation result of one or more of the two skills. May be. When all six skills are not used for UI change determination, the skill may be estimated for the skills used for UI change determination.

  In the case where all six skills are not used for UI change determination, which skill is used in the present embodiment is one of four skills of attitude, space grasping ability, visual search ability, and working memory. And at least one of the six skills including experience and motor skills is included in the four skills.

  When the UI change method is determined, the process proceeds to step S16, where information on the determined UI change method is passed from the UI processing unit 108 to the UI change unit 110, and the UI change unit 110 changes the UI for the user. , And the process ends. Here, the UI change processing is not limited to a specific method. For example, the UI change unit 110 may notify the terminal of the information on the change method, and may cause the terminal to make the change. The server may make the change.

(Estimation processing for each skill level)
Hereinafter, the skill level estimation processing executed in step S12 shown in FIG. 2 will be described for each skill.

<Estimation of attitude skill level>
FIG. 9 shows a flowchart corresponding to a model for estimating the skill level of the attitude from the operation log. The attitude here means whether or not you have a positive attitude toward the Internet. This model is a decision tree model using the operation log as an explanatory variable, and is classified into high skill / low skill according to a conditional branch.

  First, the skill estimating unit 104 reads an operation log in step S1-1. In step S1-2, it is determined whether the time interval between touches is less than 2955.9. The units of numerical values in the description of the skill level estimation process are the units shown in FIGS.

  In step S1-2, if the time interval between touches is not less than 2955.9, the process proceeds to step S1-3, where it is determined that the skill is low, and the process ends. If it is less than 2955.9 in step S1-2, the process proceeds to step S1-4, it is determined that the skill is high, and the process ends.

  In the model for estimating the skill level of the attitude in the present embodiment, the time interval between touches is used as an explanatory variable, and the value of the branch criterion is 2955.9. However, the value of the branch criterion is an example, and is not limited thereto. .

  First, the skill estimating unit 104 reads an operation log in step S2-1. In step S2-2, it is determined whether the total number of displayed pages is 0.191 or more.

  In step S2-2, if the total number of displayed pages is not 0.191 or more, the process proceeds to step S2-3, where it is determined that the skill is low, and the process ends. In step S2-2, if it is 0.191 or more, the process proceeds to step S2-4, it is determined that the skill is high, and the process ends.

  In the model for estimating the skill level of experience in the present embodiment, the total number of displayed pages is used as an explanatory variable, and the value of the branch criterion is set to 0.191. However, the value of the branch criterion is merely an example. Absent.

  The experience is defined in advance by a method that can evaluate the experience, such as the evaluation result of a questionnaire on the Internet experience (years of use and frequency of use), and the skill level standard is higher or lower than the median score. Has been set.

<Estimation of skill level of spatial grasping ability>

  In step S3-2, if the total number of displayed pages is not 0.208 or more, the process proceeds to step S3-3, where it is determined that the skill is low, and the process ends. If it is 0.208 or more in step S3-2, the process proceeds to step S3-4, where it is determined that the skill is high, and the process ends.

  In the model for estimating the skill level of the spatial grasping ability in the present embodiment, the total number of displayed pages is used as an explanatory variable, and the value of the branch criterion is set to 0.208. However, the value of the branch criterion is an example. is not.

  The spatial grasping ability is defined in advance by a method that can evaluate the spatial grasping ability, such as the result of a mental rotation test (a test in which two three-dimensional figures rotate to determine whether they are the same figure that matches and a different figure that does not match). The skill level criterion is set to be higher or lower than the median score.

<Estimation of skill level of visual search ability>
FIG. 12 shows a flowchart corresponding to a model for estimating the skill level of the visual search ability from the operation log. Here, the visual search ability is the ability to quickly and accurately find desired information from information displayed on the screen. This model is a decision tree model using the operation log as an explanatory variable, and is classified into high skill / low skill according to a conditional branch.

  First, the skill estimating unit 104 reads an operation log in step S4-1. In step S4-2, it is determined whether the contact time is less than 267.6.

  In step S4-2, if the contact time is not shorter than 267.6, the process proceeds to step S4-3, where it is determined that the skill is low, and the process ends. If it is less than 267.6 in step S4-2, the process proceeds to step S4-4, where it is determined that the skill is high, and the process ends.

  In the model for estimating the skill level of the visual search ability in the present embodiment, the contact time is used as an explanatory variable, and the reference value of the branch is set to 267.6, but the reference value of the branch is an example, and is not limited thereto. .

  In addition, as the explanatory variable used for estimation, an operation log other than the contact time may be used. For example, using the time interval of the touch, if the value is less than 2498.8, it may be determined that the skill is low, and if the value is less than 2498.8, it may be determined that the skill is high. However, also in this case, the reference value of the branch is not limited to this. Furthermore, using both the contact time and the touch time interval, for example, if at least one of the skill level determined by the contact time and the skill level determined by the touch time interval is a high skill, the skill is high. May be determined.

  The visual search ability is defined in advance by a method that can evaluate the visual search ability, such as the result of a visual search task (a task of searching for a target figure from various colors and shapes). The criterion is set to be higher or lower than the median score.

<Estimation of working memory skill level>
FIG. 13 shows a flowchart corresponding to a model for estimating the skill level of the working memory from the operation log. The working memory here refers to the ability to temporarily hold the target and the displayed information. This model is a decision tree model using the operation log as an explanatory variable, and is classified into high skill / low skill according to a conditional branch.

  First, the skill estimating unit 104 reads an operation log in step S5-1. In step S5-2, it is determined whether the touch area (moment) is less than 0.123.

  In step S5-2, if the area (moment) of the touch is not less than 0.123, the process proceeds to step S5-3, and it is determined whether the time interval of the touch is less than 2463.6.

  If it is not less than 2463.6 in step S5-3, the process proceeds to step S5-4, it is determined that the skill is low, and the process ends. If it is less than 2463.6 in step S5-3, the process proceeds to step S5-5, where it is determined that the skill is high, and the process ends. If it is less than 0.123 in step S5-2, the process proceeds to step S5-5, where it is determined that the skill is high, and the process ends.

  In the model for estimating the skill level of the working memory in the present embodiment, the area of the touch (instantaneous) and the time interval of the touch are used as explanatory variables, and the reference values of the branches are 0.123 and 2463.6, respectively. Is an example, and is not limited to this.

  The working memory is defined in advance by a method that can evaluate the working memory, such as the result of a reading span test (a test of a double task in which words in a sentence are memorized at the same time as reading a sentence). , Higher or lower than the median score.

<Estimation of athletic skill level>
FIG. 14 shows a flowchart corresponding to a model for estimating the skill level of the athletic ability from the operation log. Athletic ability here refers to the ability to move the body quickly and accurately.

  In step S6-2, if the time interval between touches is not less than 2463.6, the process proceeds to step S6-3, and it is determined whether the area (moment) of the touch is 0.133 or more.

  If it is not 0.133 or more in step S6-3, the process proceeds to step S6-4, where it is determined that the skill is low, and the process ends. If it is 0.133 or more in step S6-3, the process proceeds to step S6-5, where it is determined that the skill is high, and the process ends. If it is less than 2463.6 in step S6-2, the process proceeds to step S6-5, where it is determined that the skill is high, and the process ends.

  In the model for estimating the skill level of athletic ability in the present embodiment, the time interval of the touch and the area of the touch (instantaneous) are used as explanatory variables, and the reference values of the branch are 2463.6 and 0.133, respectively. Is an example, and is not limited to this.

  Motor skills are defined in advance by a method that can evaluate motor skills, such as the result of a test that applies Fitts' law (the task of sequentially tapping objects of various sizes and distances). Is set to be higher or lower than the median score. In addition to the definition using a test for evaluating athletic ability, a user who exhibits the above-mentioned phenomenon of “low hitting of a button or the like and a transition to an unintended page” which is a characteristic of a user having low athletic ability, etc. May be defined as a user having a low skill level, and the others may be defined as a user having a high skill level. “Buttons and the like” are examples of operation targets on the screen.

  Then, for example, the data of many user operation logs that "the button is repeatedly hit and the page transitions to an unintended page" is collected, and from the data, "the button is repeatedly hit and the page is transitioned to an unintended page. The feature of the operation log of the user may be extracted, a model (flow) as shown in FIGS. 9 to 14 may be created and stored in the model storage unit 105. Thereby, in step S12 in the flow of FIG. 2, the skill level of the athletic ability can be determined from the operation log based on the definition focusing on the phenomenon that “the buttons are hit repeatedly and the page transitions to an unintended page”.

(Other examples of operation logs)
In the examples described so far, various skill levels are specified using the operation log related to the operation of the touch panel, but this is an example. For example, various skill levels may be estimated using a mouse operation or an operation log on a pen tab (stylus).

  For example, when a log of mouse operation is used, the “touch time interval” on the touch panel corresponds to the time interval at which the mouse is clicked. When the operation log of the pen tab is used, the “time interval of touch” corresponds to an interval of time when the pen is pressed. Furthermore, when the operation log of the interface having the button is used, the “time interval of touch” corresponds to an interval of the time when the button is pressed.

  For example, when using a log of mouse operation, the “contact time” on the touch panel corresponds to the length of time from the time when the mouse is started to be pressed to the time when the mouse is stopped. When the operation log of the pen tab is used, the “contact time” corresponds to the length of time from the time when the pen tab starts to be pressed to the time when the pen is stopped being pressed. Further, when the operation log of the interface having the button is used, the “contact time” corresponds to the length of time from the time when the button is started to the time when the button is released.

  Further, for example, when the operation log of the pen tab is used, the “touch area” on the touch panel corresponds to the contact area when the pen is pressed with the pen tab.
