Abstract

When a user performs an operation similar to an operation hesitation, the operation procedure until the command execution is guided according to the situation in which the user falls into the operation of the command corresponding to the operation hesitation Provided is a guidance display device that can do this.
Content operated by a user for command execution is detected as a user operation sequence. If the degree of divergence calculated from the user operation sequence up to command execution and the shortest operation sequence when executing the command is greater than a predetermined value, it is determined that the user has lost his or her operation when the command is executed. An operation sequence when it is determined that the user is lost in operation is stored as a lost operation sequence. An execution command corresponding to the lost operation sequence determined to have a high degree of similarity from the user operation sequence and the lost operation sequence is extracted as a predicted command. Guidance information indicating an operation sequence corresponding to the prediction command is displayed.

Description

  The present invention relates to a guidance display device, and more particularly to a guidance display device that provides guidance information to a user who operates an information processing device or the like.

  In recent years, as information processing apparatuses such as AV equipment and car navigation systems have become multifunctional, the operation of these apparatuses has become complicated, and the difficulty of operation has become a problem. For example, as the number of functions increases, the number of operation steps until the user reaches a desired operation increases, and the user is likely to get stuck in the operation.

  As a means for solving such a problem, a technique has been proposed in which a situation in which a user is confused by an operation is detected and predetermined guidance information is provided (see, for example, Patent Document 1). The help information providing apparatus proposed in Patent Document 1 compares a required time for an operation performed by a user with a standard required time, and presents help information (guidance information) according to the comparison result.

This help information providing device detects an operation location that the user seems unfamiliar with using the time required for the operation even in an operation that requires a long step, and provides help information based on the detection result. Since it is presented, the user can efficiently obtain desired help information.
JP 2000-231429 A

  However, although the prior art disclosed in Patent Document 1 can identify where the user has begun to get lost in operation, the user is trapped because the command the user is trying to execute cannot be identified. Depending on the situation, it was not possible to provide guidance on the operation procedure up to command execution.

  The present invention has been made in view of the above problems. In other words, when the user performs an operation similar to the operation hesitation, the operation procedure up to command execution is guided according to the situation in which the user falls into the operation of the command corresponding to the operation hesitation. An object of the present invention is to provide a guidance display device that can be used.

  The present invention is based on a guidance display device that provides guidance information to a user. The present invention provides a user operation sequence detection unit that detects a user operation sequence for command execution as a user operation sequence, a user operation sequence up to command execution detected by the user operation sequence detection unit, and the shortest of the command Compared with the operation sequence, the degree of divergence between the two is calculated, and when the calculated degree of divergence is greater than a predetermined value, a ambiguity determination unit that determines that the user has lost operation when executing the command, and a ambiguity determination unit However, the user operation sequence when the user determines that he / she is lost is stored as a lost operation sequence, the user operation sequence before the execution of the command detected by the user operation sequence detection unit, and the lost operation storage unit Is compared with the confusing operation sequence stored in the table to calculate the degree of similarity between them, and determines whether the calculated degree of similarity is greater than a predetermined value. Comprising a hesitation tendency determination unit which extracts an execution command corresponding to the large and the determined lost operation sequence as a predicted command, and a guidance display control unit for displaying the guidance information corresponding to the predicted command hesitation tendency determination unit is extracted.

  Moreover, it is preferable that a guidance display control part displays the shortest operation sequence corresponding to a prediction command as guidance information.

  Moreover, it is preferable that a guidance display control part displays the operation procedure from the position of the present operation to command execution among the shortest operation series corresponding to a prediction command as guidance information.

  The guidance display control unit preferably displays the guidance information when the user performs an operation from the child side to the parent side of the menu of the tree configuration after the ambiguity determination unit extracts the prediction command.

  In addition, it is preferable that the lost determination unit classifies the lost operation sequence as a child sequence starting from an operation as a starting point, and generates a similar lost operation sequence in which the order of the classified child sequences is changed.

  Moreover, it is preferable that the user operation sequence detection unit manages the detected user operation sequence in two types of status and command execution.

  In addition, the user operation sequence detected by the user operation sequence detection unit preferably does not include a POI information search operation.

  The degree of divergence is preferably the ratio or difference between the number of operations in the user operation sequence and the number of operations in the shortest operation sequence.

  Moreover, it is preferable that a guidance display control part displays guidance information, when a user requests | requires.

  Moreover, it is preferable that a guidance display control part displays the name of the command corresponding to the lost operation memorize | stored in the lost operation storage part as a list as guidance information.

  As described above, according to the present invention, when the user performs an operation similar to the operation ambiguity, the command is operated according to the situation in which the user falls into the operation of the command corresponding to the operation ambiguity. It is possible to provide a guidance display device that can provide guidance on operation procedures up to execution.

  The guidance display device of the present invention will be described below with reference to the drawings. In each drawing, components not related to the present invention are omitted. In the present embodiment, description will be made assuming that the guidance display device is a car navigation system attached to a vehicle.

  Note that the guidance display device of the present invention detects the “stuck” with respect to the menu operation of the user and stores the operation history at this time (learning function), and the same in the past when the user is lost in the operation. It has two functions of a function (guidance function) for presenting an appropriate guidance based on an operation history when he / she is lost in various situations.

  The learning function is intended to memorize the operations that the user is not good at, and the guidance function is intended to provide appropriate guidance according to the situation in which the user is in trouble when the user is lost. To do.

  FIG. 1 is a block diagram showing an overall configuration of a guidance display device 10 according to an embodiment of the present invention. A guidance display device 10 according to the present embodiment includes an input unit 1, a display unit 2, a control unit 3, a user operation sequence detection unit 4, a hesitation determination unit 5, a hesitation operation storage unit 6, and a guidance display control unit 7. .

  The input unit 1 is, for example, an operation panel for receiving an input of a command or the like. Here, as an example, it is assumed that the touch panel is formed on the display unit 2. Note that the present invention is not limited to the touch panel, and may be a keyboard, a mouse, a joystick, a remote control, a voice input microphone, or the like, and may be provided with a plurality of types of input devices.

  The display unit 2 is, for example, a display that displays various types of information. Here, in particular, guidance information is displayed. The control unit 3 is, for example, a CPU that controls the entire guidance display device 10.

  The user operation sequence detection unit 4 detects a user operation at the input unit 1 and temporarily stores the operation sequence. Specifically, a history of pressing a menu button on the touch panel by the user is temporarily stored in a memory such as a RAM (Random Access Memory) and managed.

  Here, in a general information processing apparatus, the menu operated by the user is designed in a hierarchical manner, and the user's operation includes a “state” for reaching a desired command operation and finally a desired command. There are two types of “command execution” to be executed. The user operation sequence detection unit 4 classifies user operations into the above two types based on whether the attribute of the menu button pressed by the user corresponds to command execution.

  Hereinafter, the above-described two types of operations will be described by taking the operation of car navigation as an example. Here, it is assumed that the user desires to check the currently set route and performs a car navigation operation.

  First, when the user selects the “destination” button on the screen shown in FIG. 2 (menu screen A), the car navigation screen changes to the screen shown in FIG. 3 (menu screen B). In this operation, the command for confirming the route desired by the user is not executed, and the user narrows down the command candidates in order to reach the command for confirming the route (narrowing operation).

  Next, when the user performs an operation of selecting “route confirmation” from the menu button shown on the menu screen B, a command for displaying a screen showing route information is executed (command execution).

  Here, the above-described state is not limited to the operation that narrows down the candidates correctly, and includes, for example, an operation that is performed when the user is confused and is performing trial and error. For example, in the above example, the user presses the “navigation setting” button instead of pressing the “destination” button, which is the optimal operation for reaching the “route confirmation” on the first menu screen A, and FIG. If the user notices an error and presses the “Return” button on the menu screen C, the operations are also classified as narrowing operations. That is, the state corresponds to all operations other than command execution.

  However, in the state, as in the case where the user uses a function for searching POI information such as surrounding facilities installed in the car navigation system (for example, a specific facility is displayed on the menu screen shown in FIG. 5). Search)), it does not include operations that move forward and backward through trial and error. Specifically, when it is detected that the search for POI information is started (for example, when the “search for department store” button is pressed on the “search for nearby facilities” screen), a command execution related to POI search is executed at that time. It is assumed that subsequent operations for retrieving specific POI information are not temporarily stored.

  The user operation sequence detection unit 4 stores the transition of the menu screen when managing the operation sequence of the state. As in the above example, when the user selects the “destination” button on the menu screen A and transitions to the menu screen B, and selects the “route confirmation” button here to execute the command, the “menu screen A series of “A” → “menu screen B” → “route confirmation command execution” is stored. Here, “menu screen A” and “menu screen B” stored by the user operation sequence detection unit are “states”.

  The hesitation determination unit 5 detects hesitation in the user's operation based on the user's operation sequence. The hesitation determination unit 5 includes two hesitation determination means, ie, a hesitation determination means in the learning function and a hesitation determination means in the guidance function.

  The hesitation determination in the learning function is performed as follows. When the user operation sequence detection unit 4 detects that the user has executed the command, the hesitation determination unit 5 compares the operation sequence operated until the user actually executes the command with the shortest operation sequence of the command. The degree of divergence between them is calculated. If the calculated degree of divergence is greater than a predetermined value, it is determined that the user has lost operation when the user executes the command.

  The degree of divergence is, for example, the ratio of the number of operations up to command execution in the user operation sequence and the number of operations up to command execution in the shortest operation sequence. Here, the divergence degree is a value obtained by dividing the number of operations up to command execution in the user operation series by the number of operations up to command execution in the shortest operation series, and the divergence degree is a predetermined value (here, 2 It is determined that the user is lost in operation.

  With reference to FIG. 6, the operation of the determination of the doubt in the learning function of the determination unit 5 will be described. In FIG. 6, when executing the command A, the user operation sequence matches the shortest operation sequence, and the number of operations up to command execution in the user operation sequence and the number of operations up to command execution in the shortest operation sequence are Both are 2 (state a, state b). Therefore, the divergence degree is 1, and the hesitation determination unit 5 determines that the user is not at a loss.

  On the other hand, in the operation of the command B, the number of operations until the command execution in the user operation sequence is 7, the number of operations until the command execution in the shortest operation sequence is 3, and the divergence exceeds 2, so the determination is lost. The unit 5 determines that the user is lost in operation. As described above, the hesitation determination unit 5 detects a user's hesitation by monitoring the user's operation sequence and obtaining the degree of deviation from the shortest operation sequence.

  In the above example, the degree of divergence used by the ambiguity determination unit 5 is a value obtained by dividing the number of operations up to command execution in the user operation sequence by the number of operations up to command execution in the shortest operation sequence. However, the method of calculating the divergence is not limited to this method, and any method may be used as long as the degree of divergence between the user operation sequence and the shortest operation sequence is indicated.

  For example, the difference in the number of operations between the user operation sequence and the shortest operation sequence may be used. Further, the time taken for the operation may be used for calculating the degree of deviation. For example, the actual operation time may be compared with the standard operation time for the corresponding operation, and when the deviation is large, the degree of deviation may be determined to be large.

  The lost operation storage unit 6 stores a user operation sequence and a shortest operation sequence for the operation that the lost determination unit 5 determines to have lost. In the example of FIG. 6, the user operation sequence for the command B execution for which the operation determination is detected by the determination determination unit 5 and the shortest operation sequence corresponding to the command B execution are stored in the determination operation storage unit 6. The lost operation storage unit 6 is realized by a nonvolatile memory such as an HDD. In the following, the user operation sequence when the user is lost in operation is referred to as a lost operation sequence.

  As illustrated in FIG. 7, the lost operation storage unit 6 stores the lost operation sequence in association with the lost operation sequence in association with each command lost by the user. Hereinafter, the lost operation sequence and the shortest operation sequence corresponding to the lost operation sequence N (N is an integer) in FIG. 7 are referred to as the lost operation sequence N and the shortest operation sequence N, respectively.

  Next, a description will be given of the determination of the tendency to be lost in the guidance function, which is another function of the determination unit 5. The hesitation determination unit 5 compares the user operation sequence detected by the user operation sequence detection unit 4 with the hesitation operation sequence stored in the hesitation operation storage unit 6 when the user is performing an operation. Calculate similarity. If the calculated degree of similarity is greater than a predetermined value, it is determined that the user tends to be confused about an operation in the same manner as trying to execute a command that has been confused with an operation in the past.

  Hereinafter, the above-described similarity calculation method will be described in detail. In general, when the operation system has a hierarchical menu structure, the relationship between each state and command execution is represented by a tree structure as shown in FIG. The hesitation determination unit 5 calculates the similarity based on the state of the operation sequence in the tree configuration.

  In such a tree-like menu structure, the operation is performed in the shortest time when the state of all operations is changed from the parent side to the child side of the tree. For example, in FIG. 7, when the command B is executed from the state c, the state changes from the parent side to the child side as “state c” → “state f” → “state j” → “command B execution”. The case is the shortest procedure. The menu structure shown in FIG. 8 corresponds to the operation sequence shown in FIG.

  On the other hand, when the user is confused about the operation, not only the operation from the parent side to the child side but also the operation from the child side to the parent side is generally included. Taking the lost operation sequence 1 in FIG. 7 as an example, as is clear from FIG. 8, the operation from state d to state c and from state e to state c is an operation from the child side to the parent side. is there.

  Here, when the lost operation sequence 1 is divided by the operation from the child side toward the parent side, as shown in FIG. 9, “state c” → “state d”, “state c” → “state e”, “state c” ”→“ state f ”→“ state j ”→“ command B execution ”. These child sequences are operation sequences starting from the state c. As described above, when an operation from the child side to the parent side is included, there is one or a plurality of states serving as a starting point of the operation.

  Here, if the child sequence 3 leading to the execution of the command B is excluded, the child sequences starting from the same starting point c (the child sequence 1 and the child sequence 2) are the same even if the execution order is reverse. It can be considered that he is lost. Therefore, as shown in FIG. 10, the lost operation sequence 1 ′ in which the child sequence 1 and the child sequence 2 of the lost operation sequence 1 are interchanged can be regarded as a lost operation sequence for the command B execution. Hereinafter, an operation sequence in which the order of child sequences of the original lost operation sequence is changed is referred to as a similar lost operation sequence.

  For the reasons described above, the confusing determination unit 5 decomposes the original confusing operation sequence into child sequences starting from one or a plurality of starting points, and determines the order of other child sequences excluding the child sequence leading to command execution. The replaced similar lost operation sequence is generated, and the generated similar lost operation sequence is added as a lost operation sequence corresponding to command execution. Typically, this process is executed when the learning function is detected and the similar operation sequence is stored in the operation storage unit 6 together with the original operation sequence. When a plurality of the same child series exist as a result of extracting the child series, only one of the overlapping child series may be used for generating the similar lost operation series.

  In addition, regarding the child sequence at the top of the original user operation sequence among the child sequences, the start of the child sequence is not always the starting point of the operation. For example, the confusing operation sequence 2 in FIG. 7 is decomposed into child sequences as shown in FIG. 11, and the child sequence 21 at the top of the sequence is the head of the operation starting from “ It is desirable to consider the child sequence 21 as an operation sequence starting from “state d” when generating a similar lost operation sequence by changing the order of the child sequences instead of “state c”.

  In order to cope with such a situation, the ambiguity determination unit 5 has a state in which the child sequence at the head of the original user operation sequence starts from another child sequence (state d in the above example). Is included, the previous state (state c in the above example) is deleted. In the above example, assuming that the lost operation sequence is an operation sequence as shown in FIG. 12, a similar lost operation sequence is generated.

  The hesitation determination unit 5 determines the similarity based on, for example, the number of consecutive user operation sequences and the hesitation operation sequence (including the similar hesitation operation sequence) (the number of consecutive matches). Here, when the number of consecutive matches between the user operation sequence and the lost operation sequence is 5 or more, it is determined that the user is similarly lost with respect to the same command that was lost in the past.

  The ambiguity determination unit 5 extracts a command corresponding to the ambiguity operation sequence whose similarity exceeds a predetermined value as a prediction command. The prediction command is a command predicted from the past history that the user desires an operation.

  With reference to FIG. 13, the operation of predictive command extraction in the ambiguity determination unit 5 will be described. In FIG. 13, when the user operation sequence is compared with the lost operation sequence, the number of the similar lost operation sequences 1-1 in which the states continuously match is 5, which satisfies the above-described determination criteria. Therefore, the command B corresponding to the similar lost operation sequence 1-1 is extracted as a predicted command.

  In the above-described example, the similarity used in the ambiguity determination unit 5 is a number in which the user operation sequence and the ambiguity operation sequence are continuously matched. However, the similarity calculation method is not limited to this method. Any method may be used as long as the degree of similarity between the user operation sequence and the lost operation sequence is indicated.

  For example, the ratio of the number of operations in which the user operation sequence and the lost operation sequence are continuously matched may be used. Further, instead of using the number or ratio of the user operation series and the lost operation series that are continuously matched, the number or ratio of matching the user operation series and the child series of the lost operation series may be used. In addition, the number of matches or the percentage of matches between the number of operations of the user operation sequence and the lost operation sequence actually operated by the user may be used without using the concept of the child sequence.

  The guidance display control unit 7 causes the display unit 2 to display a guidance on the operation method of the prediction command extracted by the determination unit 5. Typically, the shortest operation sequence corresponding to the target operation sequence is presented to the user through a video demonstration.

  For example, as shown in FIG. 14, a moving image in which a button to be selected next is pressed with a finger-shaped icon is displayed in order. Thereby, when the user forgets the operation procedure up to the execution of the command that has been operated in the past, the user can be specifically taught the operation procedure, so that the command can be easily executed. Furthermore, by showing a specific operation procedure as an image with a moving image, the user can more easily store the operation, and the possibility of getting lost in the operation from the next time is reduced.

  In addition, when the shortest operation sequence is shown as a video, if the menu screen state at the time of guidance presentation is not the first state of the shortest operation sequence but in the middle, the command execution procedure from the current state is shown. Guidance may be displayed.

  For example, when the shortest sequence of operations is “state x” → “state y” → “state z” → “command Z execution”, when the current state is state y, the state y goes to command Z Guidance display of the operation sequence.

  The guidance display may be presented when the user performs an operation from the child side to the parent side of the tree structure after detecting the prediction command. When moving from the parent side to the child side, there is a possibility that the desired command execution can be reached as it is, and no guidance is displayed even if a predicted command is extracted. When the user performs an operation from the child side toward the parent side (when it is confirmed that he / she is lost), the corresponding guidance is displayed for the first time.

  Further, the guidance may be displayed when the determination of the learning function is made. As a result, the user can immediately confirm the correct operation method for the operation lost immediately before, and can store the operation method more strongly.

  The guidance display is not limited to the moving image display as described above, and any guidance display may be used as long as it explains the operation method for the predicted operation. Alternatively, a button that can execute the predicted command as it is may be arranged and executed using the button.

  In addition, when a plurality of commands are detected as a predicted command for a certain user operation sequence, a list of predicted commands may be displayed and a user may select from the list, or guidance for commands with higher similarity may be provided. You may make it display.

  Next, the operation in the learning function of the guidance display device according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

  First, when the user starts an operation using the input unit 1, the user operation sequence detection unit 4 detects the user's operation (step S1) and determines whether the operation performed by the user is command execution (step S2). ). Here, the start of the user's operation is the next operation after the execution of the previous command, that there is more than a predetermined time from the previous operation, and the current state is operated by the user such as the top of the menu hierarchy. It is detected by the menu screen that starts.

  In step S2, if the operation performed by the user is not command execution, detection of the user operation is continued.

  On the other hand, when it is detected in step S2 that the user has performed a command execution operation, the ambiguity determination unit 5 compares the user operation sequence with the shortest operation sequence for the executed command (step S3), A divergence degree is calculated, and it is determined whether or not the calculated divergence degree is larger than a predetermined value (step S4).

  In step S4, when the divergence degree is larger than a predetermined value, it is determined that the user has lost the operation when executing the command, and the user operation sequence at that time (the lost operation sequence) and the shortest operation corresponding to the command are determined. The series is stored in the lost operation storage unit 6 as a lost operation corresponding to the command (step S5).

Further, the hesitation determination unit 5 generates a similar hesitation operation sequence by decomposing the user operation sequence at that time into child sequences (step S6). Then, the confusing determination unit 5 stores the generated similar confusing operation sequence as the confusing operation sequence corresponding to the command in the confusing operation storage unit 6 (step S7), and ends the processing of the learning function.

  On the other hand, if the divergence degree is equal to or less than a predetermined value in step S4, it is determined that the user has not lost his or her operation when executing the command, and the process of the learning function is terminated as it is.

  Next, the operation of the guidance function of the guidance display device according to the present invention will be described with reference to the flowchart of FIG.

  First, when a user starts an operation using the input unit 1, the user operation sequence detection unit 4 detects the user's operation (step S11), and determines whether the operation performed by the user is command execution (step S12). ).

  In step S12, when the user executes a command, the guidance function processing is terminated.

  On the other hand, in step S12, when the operation performed by the user is not command execution, the hesitation determination unit 5 compares the user operation sequence with the hesitation operation sequence stored in the hesitation operation storage unit 6 (step S13). And the similarity between them is calculated and it is determined whether the calculated similarity is larger than a predetermined value (step S14).

  In step S14, when the similarity is equal to or less than a predetermined value, the detection of the user operation is continued.

  On the other hand, if the degree of similarity is greater than a predetermined value in step S14, it is determined that the user is confused with the operation, guidance for executing the corresponding command is displayed (S15), and the guidance function processing is performed. finish.

  As described above, the learning function and the operation of the guidance function of the guidance display device according to the present invention have been described separately, but in the actual operation, the operations for both functions are performed simultaneously. The overall operation of the guidance display device according to the present invention will be described with reference to the flowchart of FIG.

  First, when the user starts an operation using the input unit 1, the user operation sequence detection unit 4 detects the user's operation (step S21), and determines whether the operation performed by the user is command execution (step S22). ).

  In step S22, when the operation performed by the user is not command execution, the hesitation determination unit 5 compares the user operation sequence with the hesitation operation sequence (step S23). Then, the similarity between them is calculated, and it is determined whether or not the calculated similarity is a predetermined value or more (step S24).

  If the similarity is greater than or equal to a predetermined value in step S24, guidance is displayed (step S25).

  On the other hand, if it is smaller than the predetermined value in step S24, detection of the user operation is continued. That is, when the operation performed by the user is not command execution, an operation corresponding to the guidance function is performed.

  On the other hand, in step S22, when the operation performed by the user is command execution, the hesitation determining unit 5 compares the user operation sequence with the shortest operation sequence for the executed command (step S26). Then, a divergence degree between them is calculated, and it is determined whether or not the calculated divergence degree is a predetermined value or more (step S27).

  In step S27, when the degree of divergence is equal to or greater than a predetermined value, the ambiguity determination unit 5 stores the shortest operation sequence corresponding to the command (step S28). Then, the ambiguity determination unit 5 generates a similar ambiguity operation sequence (step S29), and stores the generated similar ambiguity operation sequence in the ambiguity operation storage unit (step S30).

  On the other hand, if the divergence degree is smaller than the predetermined value in step S27, the process is terminated as it is. That is, when the operation performed by the user is command execution, an operation corresponding to the learning function is performed.

  As described above, when the user performs an operation similar to the operation hesitation, the operation procedure until the command execution is performed according to the situation in which the user falls into the operation of the command corresponding to the operation hesitation. A guidance display device that can provide guidance can be provided.

  In the above example, the guidance display is presented when it is detected that the user is confused with the operation. However, the guidance display may be presented when requested by the user. For example, it is presented when a user presses a predetermined button for calling a guidance presentation function.

  In this case, the history that the user has lost in the past is displayed as a list as shown in FIG. At this time, based on the user operation sequence operated until the user requests the guidance presentation, the similarity with the lost operation sequence may be calculated and displayed so as to be arranged from the highest similarity to the top of the list. . When the user selects a desired history (command) from the displayed list, the corresponding guidance is displayed on the display unit 2. Alternatively, the selected command may be executed as it is.

  By displaying the user's operation history in this way, it is possible to easily call up the operation guidance or execute the operation when it is desired to perform a poor operation with a memory that has been lost in the past. it can.

  The configuration described in the above embodiment is merely a specific example and does not limit the technical scope of the present invention. Any configuration can be employed within the scope of the effects of the present application.

  The guidance display device of the present invention is useful as an information processing device such as a car navigation device installed in a vehicle.
