Description

  The present invention relates to a technique for detecting character input including input of a character string that is not appropriate for collecting information when inputting characters in a wide variety of applications and supporting character input.

  Conventionally, in a search service, when a character string is entered in the search box, a search candidate is added by interpolating the input character string with forward matching and adding words that are likely to co-occur in the entered character string as a search query. Thus, a suggestion function for assisting the user in searching for desired information is used.

  In Patent Document 1, the user's operation proficiency level is determined according to the display time of each screen, the ratio of valid keys (for example, the ratio at which an operation is accepted when an operation surface is instructed), etc., and the proficiency level is low. In this case, an object operation technique of presenting an operation tutorial display is disclosed.

  Further, in Patent Document 2, it is noted that a user who is unfamiliar with the operation of the information processing apparatus may be confused if a plurality of operation methods are prepared. A technique is disclosed in which the proficiency level is associated with the operation method guidance and the operation method is guided when the proficiency level changes.

JP, 2014-016781, A JP 2010-218359 A

  In general, character input operations include various applications and web pages (hereinafter simply referred to as input for creating mail, input for a search engine such as Google (registered trademark), search for a map, etc.). (Also called application).

  For character input operations in such applications, users who are accustomed to character input operations in the application can enter a character string that matches the characteristics of the application. Then, by determining or transmitting, the user can obtain a desired result. However, on the other hand, there is a problem that it is difficult for a user unfamiliar with the operation of the application to input characters according to the application.

  As a method for dealing with such a problem, there is a suggestion function by a search service as described above. However, when there are no candidates that the user desires among the suggested candidates, or when the suggested candidates cannot be displayed because the display screen is small as shown in FIG. 5, the character input operation is performed. An unfamiliar user does not know how to input next and has not solved the problem.

  In addition, as a specific example of a situation that a user unaccustomed to character input operations may face, in the map search as shown in FIG. 6A, when a store name in the input component is input, there are too many suggestion results, Is not fully displayed. In such a state, when the enter or search key is pressed to move to the next screen, a map of the neighborhood using the GPS of the device itself or a map of a wide area is displayed on the screen. It is also conceivable that the situation does not necessarily match the map regarding the store in the desired area. A user who is unfamiliar with the character input operation may not know what operation should be performed thereafter.

  Further, in the web search as shown in FIG. 6B, since the sentence is input to the input component, only the same sentence is displayed as the suggestion result. As described above, when a sentence is input to the input component and the determination or search key is pressed, there is a possibility that information desired by the user cannot be obtained, for example, the result of the suggestion becomes too small.

  Such situations can occur in a wide variety of applications. Such inconvenience must be supported by each service provider, but there is also a problem that it is difficult for others to modify.

  Further, since Patent Document 1 refers only to object operations and does not refer to advice related to linguistic problems, it cannot cope with input that is inappropriate for the user to obtain desired information.

  Further, in Patent Document 2, a tutorial is performed using a change in proficiency as a trigger. Therefore, when inputting characters in a wide variety of applications, erroneous input including input of a character string that is not appropriate for collecting information is included. I can't respond.

  The present invention has been made in view of such circumstances, and detects erroneous input including input of a character string that is not appropriate for collecting information when inputting characters in a wide variety of applications. It is an object of the present invention to provide an input support device, a program, and an input support method that can prompt a user who is unfamiliar with character input operations to perform appropriate input.

  (1) In order to achieve the above object, the present invention takes the following measures. That is, an input support device that supports character input, and based on a user operation, determines an input unit that inputs a character string and a current application type, and characters that are associated with the determined application type in advance. An application type discriminating unit that identifies a column transmission destination, an information collection unit that collects information determined for each application type from the identified character string transmission destination using the input character string, and the collected information And an advice input unit for presenting advice corresponding to the detected erroneous input before and after performing an operation corresponding to the determined application type by the user. And.

  Thus, based on the user's operation, a character string is input, the current application type is determined, a character string transmission destination previously associated with the determined application type is specified, and the input character string is used. Before and after executing the operation corresponding to the application type determined by the user by detecting the user's erroneous input based on the collected information, collecting information determined for each application type from the specified character string transmission destination Since the advice corresponding to the detected erroneous input is presented, the application characteristics are determined before the user decides or executes the input operation for the erroneous input by the user or before the second execution after the first execution. It is possible to present an advice according to the user, and to prompt a user who is unfamiliar with the character input operation to input an appropriate character string. As a result, it is possible to collect appropriate information desired by the user, and to improve the skill of the user's own character input operation.

  (2) Further, in the input support device of the present invention, the erroneous input detection unit detects an input as an erroneous input when a character string that is not appropriate for collecting information is input.

  As described above, when a character string that is not appropriate for collecting information is input, the erroneous input detection unit detects the input as an erroneous input. When a character string that does not match is input, or when a character string that is inappropriate for efficiently obtaining the information that the user wants is input, it is detected as an erroneous input, and it depends on the characteristics of each application. It is possible to provide advice on character input operations.

  (3) Further, in the input support device of the present invention, the information collection unit collects the information via a database or a network that stores information collected in advance.

  In this way, the information collection unit collects information via a database or network that stores pre-collected information, so information collected when a character string input by the user is determined or executed. Collecting in advance, detecting an erroneous input according to the characteristics of each application, it becomes possible for the user to present advice before completing the input operation of the character string.

  (4) Further, in the input support device of the present invention, the erroneous input detection unit is configured such that the number of input character strings is less than or equal to a first threshold and the number of collected information is greater than or equal to a second threshold. In some cases, it is detected as an erroneous input.

  As described above, the erroneous input detection unit detects an erroneous input when the number of input character strings is equal to or less than the first threshold and the number of collected information is equal to or greater than the second threshold. By presenting advice to the user to increase the number of character strings to be performed, it is possible to prevent an excessive amount of collected information due to an insufficient number of input character strings and efficiently collect and provide appropriate information desired by the user It becomes like this.

  (5) Further, in the input support device of the present invention, the erroneous input detection unit is configured such that the number of input character strings is greater than a first threshold and the number of collected information is less than a second threshold. In some cases, it is detected as an erroneous input.

  Thus, the erroneous input detection unit detects an erroneous input when the number of input character strings is greater than the first threshold and the number of collected information is less than the second threshold. By presenting the advice to the user so as to reduce the number of input character strings, it is possible to prevent the collected information from being insufficient due to the excessive number of input character strings and to collect and provide appropriate information desired by the user.

  (6) Further, in the input support device of the present invention, the erroneous input detection unit detects an erroneous input when the input character string length is equal to or greater than a third threshold value.

  As described above, when the input character string length is greater than or equal to the third threshold value, the erroneous input detection unit detects an erroneous input, so the input character string is segmented into short segments such as phrases or words instead of sentences. By presenting the advice to the user for input, it is possible to prevent the collected information from being insufficient due to the redundancy of the input character string, and to appropriately collect and provide the user as desired.

  (7) Moreover, in the input support device of the present invention, the erroneous input detection unit is configured such that the input character string length is equal to or greater than a third threshold value, and the number of clauses of the character string is equal to or greater than a fourth threshold value. In some cases, it is detected as an erroneous input.

  Thus, the erroneous input detection unit detects an erroneous input when the input character string length is equal to or greater than the third threshold and the number of clauses of the character string is equal to or greater than the fourth threshold. Even when a sentence containing a word with many characters is input, it is possible to reduce the redundancy of the input string by presenting advice to the user so that the input character string is divided into short phrases and words instead of sentences. Therefore, it is possible to prevent the collected information from being insufficient, and to collect and provide appropriate information desired by the user.

  (8) Further, in the input support device of the present invention, the erroneous input detection unit relates to at least the number of input character strings, the character string length, the number of phrases, the part of speech, the number of collected information, and erroneous input detected in the past. A feature extracted from any of the history information is used as a feature amount, and an erroneous input is detected from the feature amount.

  As described above, the erroneous input detection unit is extracted from at least the number of input character strings, the length of the character string, the number of phrases, the part of speech, the number of collected information, and history information regarding erroneous input detected in the past. Since the erroneous input is detected from the feature amount, the accuracy of the user's erroneous input detection can be improved.

  (9) Further, in the input support apparatus of the present invention, the advice presenting unit presents advice using history information regarding erroneous input detected in the past.

  As described above, the advice presenting unit presents the advice using the history information regarding the erroneous input detected in the past, so that the advice can be provided with reference to the past similar erroneous input detection results. As a result, it can be understood that the user should input in the same manner as in the past, and the skill of the user's input operation can be improved.

  (10) In the input support device of the present invention, when the erroneous input detection unit acquires skill information indicating a user's input skill and the input skill indicated by the skill information is equal to or less than a fifth threshold value. , And detecting as an erroneous input.

  As described above, the erroneous input detection unit acquires skill information indicating the user's input skill, and detects the erroneous input when the input skill indicated by the skill information is equal to or less than the fifth threshold. When the skill is high, it is excluded from detection of erroneous input, and when the user's input skill is low, it is possible to perform character input support by detecting erroneous input and presenting advice.

  (11) The program of the present invention is a program of an input support device that supports character input, and determines a process of inputting a character string and a current application type based on a user operation, and the determination A process of identifying a character string transmission destination previously associated with the application type, a process of collecting information determined for each application type from the specified character string transmission destination using the input character string, A process for detecting a user's erroneous input based on the collected information and a process for presenting advice corresponding to the detected erroneous input before and after the user performs an operation corresponding to the determined application type. And causing a computer to execute a series of processes.

  Thus, based on the user's operation, a character string is input, the current application type is determined, a character string transmission destination previously associated with the determined application type is specified, and the input character string is used. Before and after executing the operation corresponding to the application type determined by the user by detecting the user's erroneous input based on the collected information, collecting information determined for each application type from the specified character string transmission destination Since the advice corresponding to the detected erroneous input is presented, the application characteristics are determined before the user decides or executes the input operation for the erroneous input by the user or before the second execution after the first execution. It is possible to present an advice according to the user, and to prompt a user who is unfamiliar with the character input operation to input an appropriate character string. As a result, it is possible to collect appropriate information desired by the user, and to improve the skill of the user's own character input operation.

  (12) The input support method of the present invention is an input support method for an input support apparatus that supports character input, and the step of inputting a character string and the current application type are determined based on a user operation. And identifying the character string transmission destination previously associated with the determined application type, and collecting information determined for each application type from the identified character string transmission destination using the input character string And a step of detecting an erroneous input of the user based on the collected information, and an advice corresponding to the detected erroneous input before and after executing an operation corresponding to the determined application type by the user. And at least a step of presenting.

  Thus, based on the user's operation, a character string is input, the current application type is determined, a character string transmission destination previously associated with the determined application type is specified, and the input character string is used. Before and after executing the operation corresponding to the application type determined by the user by detecting the user's erroneous input based on the collected information, collecting information determined for each application type from the specified character string transmission destination Since the advice corresponding to the detected erroneous input is presented, the application characteristics are determined before the user decides or executes the input operation for the erroneous input by the user or before the second execution after the first execution. It is possible to present an advice according to the user, and to prompt a user who is unfamiliar with the character input operation to input an appropriate character string. As a result, it is possible to collect appropriate information desired by the user, and to improve the skill of the user's own character input operation.

  According to the present invention, even a user who is unfamiliar with the character input operation is presented with advice according to the characteristics of each application for the input character string, so that an appropriate character string can be input. . As a result, it is possible to collect appropriate information desired by the user, and to improve the skill of the user's own character input operation.

It is a block diagram which shows schematic structure of the input assistance apparatus which concerns on this embodiment. It is a flowchart which shows the operation example of the input assistance apparatus which concerns on this embodiment. It is the figure which showed an example of the structure of application classification DB. It is a figure which shows the example which presented the advice. It is a figure which shows the example of a suggestion of a search engine. It is a specific example of the problem in the search within an application.

  The present inventor notices that a user who is not accustomed to a character input operation cannot obtain the information desired by the user because the user does not understand the input operation or an erroneous input resulting from an inappropriate input for the user to obtain desired information. In addition, by detecting user's whisper according to the characteristics of each application and providing advice on input operation, it is possible to collect appropriate information desired by the user, and further, the user's own character input operation skills It has been found that improvement can be achieved, and has led to the present invention.

  That is, the input support device of the present invention is an input device that supports character input, and based on a user operation, determines an input unit that inputs a character string and a current application type, and determines the determined application type. An application type discriminating unit that identifies a character string transmission destination associated in advance, and an information collecting unit that collects information determined for each application type from the identified character string transmission destination using the input character string And an erroneous input detection unit that detects an erroneous input of the user based on the collected information, and an advice corresponding to the detected erroneous input before and after performing an operation corresponding to the determined application type by the user And an advice presenting section for presenting.

  As a result, the present inventor can input an appropriate character string even for a user who is unfamiliar with the character input operation by presenting advice according to the characteristics of each application to the input character string. Made possible. As a result, it is possible to collect appropriate information desired by the user, and further improve the skill of the user's own character input operation. Embodiments of the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a block diagram illustrating a schematic configuration of the input support apparatus according to the present embodiment. This input support apparatus includes a control unit 1, an input unit 3, an input character string storage unit 5, an application type DB 7, an application type determination unit 9, a character string transmission unit 11, an information collection unit 13, an information reception unit 19, an erroneous input detection Unit 21, advice generation unit 23, and advice presentation unit 25.

  The control unit 1 controls each component. The input unit 3 inputs a key (application selection or character) corresponding to the coordinates based on the input coordinates touched by the user. The input character string storage unit 5 stores the character string input by the input unit 3.

  The application type DB 7 holds at least a condition indicating a plurality of application types such as a URL, an application name, or an image of the application, and a character string transmission destination corresponding to each application type. For each application type, the character string transmission destination may be held in a one-to-one correspondence manner or may be held in a N-to-M correspondence manner. An example of the configuration of the application type DB 7 will be described later.

  The application type determination unit 9 acquires information on the selected application from the input unit 3, and determines the currently active application type using the acquired information. Information on the application type determined to be currently active is acquired from the application type DB 7 and transmitted to the character string transmission unit 11.

  The character string transmission unit 11 transmits the character string acquired from the input character string storage unit 5 to the character string transmission destination acquired from the application type determination unit 9.

  According to the transmission method acquired from the application type discriminating unit 9, the information collecting unit 13 receives information determined for each application type such as the number of searches and the number of suggestions for the search engine via the DB 17 or the network 15 as an input character string. The character string acquired from the storage unit 5 is collected, and if necessary, a shaping process is performed and transmitted to the information receiving unit 19. The information receiving unit 19 acquires information collected by the information collecting unit 13.

  The erroneous input detector 21 detects an erroneous input based on the information acquired by the information receiver 19, the input character string, and the application type. Here, erroneous input includes input of a character string that is not appropriate as a character string for collecting information, in addition to erroneous input by a user.

  The advice generation unit 23 generates advice in association with the erroneous input detected by the erroneous input detection unit 21. The advice presentation unit 25 presents the advice generated by the advice generation unit 23 to the user.

  FIG. 2 is a flowchart showing an operation example of the input support apparatus according to the present embodiment. First, it is determined whether or not a character string has been input (step S1). In step S1, if no character string is input, this determination is repeated. If a character string is input in step S1, the input is detected (step S2), and the character string being input is stored in the input character string storage unit (step S3).

  Information regarding the application type in which the character string is input is transmitted to the application type determination unit, and the application type is determined (step S4). It is determined whether information regarding the determined application type exists or does not exist in the application type DB (step S5). In step S5, when there is no information regarding the application type or when the application type cannot be determined, the process proceeds to step S1. In step S5, if information related to the application type exists in the application type DB, information associated with the application type is transmitted to the character string transmission unit.

  The character string transmission unit transmits the character string transmission destination, which is one of information acquired from the application type determination unit, and the input character string acquired from the input character string storage unit to the information collection unit (step S6). The information collection unit collects information related to the input character string acquired from the input character string storage unit from the character string transmission destination acquired from the character transmission unit (step S7). The information receiving unit receives the information collected by the information collecting unit (step S8).

  Based on the received information, an erroneous input detection unit detects an erroneous input (step S9). An example of erroneous input detection timing will be described later.

  The erroneous input detection is confirmed (step S10). As a result, if no erroneous input is detected, the process proceeds to step S1. If an erroneous input is detected in step S10, advice corresponding to the erroneous input is generated (step S11), and the generated advice is presented (step S12).

(Determination of application type)
A method for determining the application type will be described. Here, for the sake of simplicity, the OS is Android (registered trademark), and the application type determination target is a mail application, a map application, and a web search application. An example in which the application type is determined from the keyboard application for an application whose transmission method is defined as DB in the determination DB will be described.

  In the OS, by using Activity Manager, the name of the application being input can be acquired from another application, so that the application type can be determined. In addition, by using Text View, it is related to the type of input component being input on the currently active application (for example, whether the search key is “search”, “line feed”, “next”, etc.) Information can also be obtained. Therefore, it is also possible to determine that erroneous input detection is performed only when the input component type target is a search.

  In addition, in the OS described above, there is a technique for determining the type of application or website based on the capture screen and the database.

  As an application type determination method, an example of determination from the keyboard application is given. However, the application type can be similarly determined on the web browser application or the OS. That is, if it is an application type on the web browser application, it is possible to determine the currently active page and easily acquire information. If the application type is determined on the OS, it can be obtained more easily.

  FIG. 3 is a diagram showing the configuration of the application type DB. The application type DB stores at least information on the application type, the application name corresponding to the application type, the transmission method, and the transmission destination. Based on the application type determined by the above-described determination method and information stored in the application type DB, a transmission destination for transmitting character string information (also referred to as an input character string) in the input component is determined.

(Information collection)
Next, an information collection method will be described. The character string input to the input component is transmitted to the information collection unit to be transmitted. As an example of the information collection method, a case where information related to a character string is collected using GET METHOD will be described.

  This is one of the types of requests sent from a client (web browser or the like) to a web server using HTTP communication, and is for requesting transmission of a file specified by a URL. Thereby, although it depends on the destination, the upper search results, the total number of searches, the suggestion contents, and the like can be acquired.

(Error detection and advice generation)
Next, processing related to erroneous input detection and advice generation will be described. An erroneous input is detected based on the character string input to the input component, the application type, and the collected information. Here, the erroneous input includes an input of a character string that is not appropriate as a character string for collecting information, in addition to an erroneous input component character string.

  The timing for detecting an erroneous input is “determined” or “transmitted” as the input component type when a certain period of time has elapsed since the last character was input to the input component, or when an erroneous input is detected at a certain interval. Suggestions before selecting "". The timing for detecting an erroneous input is not limited to these two. Hereinafter, other erroneous input detection timings will be described as detection examples.

[Detection Example 1]
When the number of character strings (hereinafter also referred to as items) separated by spaces is N (first threshold) or less and the collected results are M (second threshold) or more for the input character strings In addition, an advice to add a keyword is generated.

[Detection Example 2]
When the number of input items is more than N (first threshold) and the collection result is less than M (second threshold), advice to reduce keywords is generated.

[Detection Example 3]
Morphological analysis is performed on the input items, and if the number of particles / auxiliary verbs is greater than or equal to N (third threshold value, fourth threshold value), advice is generated that the input is divided into words.

[Detection Example 4]
Perform morphological analysis or syntactic analysis on the input item, send only the noun phrase again to the information collection unit, obtain the collected information result (here, the suggest result), and collect N or more collected information results In the case of, an advice to add a keyword is generated.

[Detection Example 5]
When the application type is map search, the case where proper nouns such as store names are included is detected by performing morphological analysis on the input item, and the place name is added when there are N or more suggestion results Generate advice to do so.

As features used for the discrimination described above,
-Number of items entered (number of strings separated by spaces)
-Character string length, number of morphemes, type of morpheme (or more roughly or subdivided information) for each item
・ Sentence form of item (whether it is a noun phrase or a sentence)
-Top search results-There are information such as the content of the suggestion, the total number, etc. However, it is not limited to the type as long as it can be acquired besides these information.

In addition, the above is based on the current character input, collection result information, and features based on application type.
・ Past trends (the above information in multiple FEP (Front End Processor) inputs)
・ Advice history contents detected in the past and the number of times ・ History information such as advice status in other applications (for example, the web search is properly performed but the map application is not successful) may be used.

  Further, not only the rule base as described above but also a classifier (SVM, CRF, etc.) learned from the feature vector used above and the erroneous input label corresponding thereto may be used.

(Presentation)
Next, presentation of advice will be described. When an erroneous input is detected, advice is generated and presented when the following conditions are satisfied.
・ Every erroneous input detection ・ When a certain time interval elapses after the same or any wrong input was detected in the past ・ The number of erroneous inputs detected since the same or any wrong input was detected in the past When exceeded

Here, the time interval and the number of detections may be constants, or may be a function F (N) of the time interval and the number of detections as shown in Equation (1), for example.
F (N) = 2N−1 (1)
N: Number of advices

  FIG. 4 is a diagram illustrating an example in which advice is presented. FIG. 4A is an image diagram in which advice is given to add place name information because there are too few items in the input character string to the input component. FIG. 4B is an image diagram in which advice is presented so that the input character string to the input component is a sentence, so that the input is divided into words. The advice may be displayed superimposed on the search screen as shown in FIG. 4 or may be presented by launching another area on the screen or another screen.

(Considering skill discrimination)
About said advice presentation, you may detect as an incorrect input only when a user's input skill is a certain fixed value or less. Alternatively, when the skill is defined in multiple stages, a threshold for detecting erroneous input (fifth threshold) may be set according to the skill.

There is no limitation on the method for determining the input skill. For example, as a web search skill, there is a method of classifying into N stages in terms of human or machine learning based on the following feature amounts.
[Feature value]
-Number of morphemes included per item-Number of items-Input string length-Number of determinations or searches included in the same item-Number of search results

For simple character input skills, there are methods for determining several stages according to the input speed WPM (Word Per Minute) and the error rate from the start of input of the first character until the last character is input. Supposing that the input speed that is a reference for a certain i stage is WPMi and the input speed acquired by the user operation is wpm,
WPMi ≤ wpm ≤ WPMi + 1
There is a method for discriminating from i-stage skills satisfying the above.

(Generate advice based on history information)
In the above example, a case has been described in which erroneous input is detected for a certain application and independent advice is generated for each erroneous input detection. However, advice may be generated based on erroneous input / input history information. . For example, if similar input is classified into a certain category and erroneous input A and erroneous input B in the same category have been performed, when erroneous input C is detected, “ It is also possible to generate advice such as “Please”.

(Other examples)
Although an erroneous input is detected and advice is generated and presented before the user actually performs a search operation, the timing of advice presentation is not limited to this. For example, the advice may be presented after the search operation is performed so that it can be appropriately input at the next operation, the advice may be presented at the next operation, or at any timing.

  In the embodiment of the present invention, a touch panel operation on a smartphone is exemplified as an example, but an operation using a hard key may be used, and the operation is not limited to a smartphone, but may be a PC or a wearable terminal such as a smartphone.

  As described above, according to the present embodiment, even a user who is unfamiliar with the character input operation is presented with advice according to the characteristics of each application for the input character string. Can be entered. As a result, it is possible to collect appropriate information desired by the user, and to improve the skill of the user's own character input operation.
