Method of Presenting Suggestion Information by Information Presentation System
Next, a method of presenting suggestion information by the information presentation system 100 will be described using the flowchart of
When an operation unit, which is not illustrated, receives an operation of the first user in the home appliance 1 (S101), the operation unit transmits the operation content of the operation to the first information management unit 11a. The first information management unit 11a that has received the operation content from the operation unit records and manages the operation content of the operation received by the operation unit and transmits the operation content to the operation information processing unit 11b. The operation information processing unit 11b that has received the operation content of the operation from the first information management unit 11a performs an operation information processing (S102). The operation information processing is a process of generating operation information representing the operation content of the operation received by the operation unit of the home appliance 1 and transmitting the generated operation information to the server 2 via the first communication unit 10.
After S102, in the server 2, the second information management unit 21a that has received the operation information via the second communication unit 20 records and manages the received operation information and transmits the operation information to the behavior prediction unit 21b. The behavior prediction unit 21b that has received the operation information detects that a specific action has been performed on at least one of the home appliance and the first communication device 3 (S10).
Here, the “specific action” refers to an action performed by a subject user on the home appliance 1 or a subject communication device with a nigh probability that the home appliance will be used after the end of the action. The “specific action” can include an action of gripping and lifting a subject communication device, an action of opening a door of a microwave oven that is an example of the home appliance 1, and the like. Each of the exemplified actions is detected by, for example, an acceleration sensor, a pressure sensor, which are not illustrated, or the like mounted in the home appliance 1, the first communication device 3, and the second communication device 4.
Note that the processing of S103 may be performed, for example, between processing of S104 and processing of S105, which will be described below, or may be performed between processing of S105 and processing of S106, which will be described below.
If a specific action is detected (S103: YES), the behavior prediction unit 21b performs behavior prediction processing on the basis of the operation information, the operating history of the home appliance 1 read from the second information management unit 21a, and the accumulated assessment information (S104). S104 is an example of a behavior prediction step in which the behavior prediction processing is a process of predicting a behavior of the subject user using the home appliance 1. Details of assessment information will be described below.
The operation history of the home appliance 1 specifically refers to an operation history of the home appliance 1 stored for each of the first user and the second user. in the present embodiment, an operation history of the various buttons for cooking accumulated for each of the first user and the second user corresponds to an operation history of the home appliance 1, for example, because the home appliance 1 is a microwave oven. Note that if the home appliance 1 is an air conditioner, an operating history of a temperature setting button accumulated for each of the first user and the second user, example, is an operation history of the home appliance 1. Also, if the home appliance 1 is a television, for example, an operation history of a channel setting button accumulated for each of the first user and the second user is an operation history of the home appliance 1.
The behavior prediction processing by the behavior prediction unit 21b is performed as follows. First, the behavior prediction unit 21b compares the operation information with the operation history of the first user and the second user and identifies, as a subject user, a user who has made more operations of the same content as that of the operation information (hereinafter, referred to as a “reference operation”) included in the operation history. Next, the behavior prediction unit 21b extracts, from the operation history of the subject user, relevant operations related to the reference operation that were performed within a predetermined period of time before and after the performance time point of the reference operation and counts the number of extractions for each different type of relevant operations.
Next, the behavior prediction unit 21b identifies candidate behaviors that are reasonably supposed from the contents of the reference operation and the contents of a predetermined number of highly ranked relevant operations with a higher number of extractions. Identification of candidate behaviors will be described taking an example in which the first user who is a subject user operates an operation unit of a microwave oven which is an example of the home appliance 1 to input “oven,” “600 W,” and “heating time: approximately 2 to 3 minutes.” In this example, “oven,” “600 W,” and “heating time: approximately 2 to 3 minutes” are reference operations together. In a case where, among a plurality of extracted relevant operations, top five relevant operations with a high number of extractions are input of “hamburger,” “meat-stuffed peppers,” “savory egg custard,” “macaroni gratin,” and “beef croquette,” the behavior prediction unit 21b identifies that the first user is going to cook a meat dish using the home appliance 1 as a candidate behavior because three of these top five relevant operations are operations related to meat dishes.
Next, the behavior prediction unit 21b identifies a correspondence relation between a series of operations including a reference operation and a relevant operation that serves as a specific basis for the candidate behavior and the accumulated assessment information for each of the series of operations in different types. Then, in a case where there are a predetermined number of pieces of assessment information corresponding to the series of operations or more, the assessment information representing positive assessment, the behavior prediction unit 21b determines the candidate behavior to be a behavior for which suggestion information is preferably presented to the subject user and finally predicts that the candidate behavior is a behavior of the subject user using the home appliance 1.
In the above example, assuming that, the standard number of pieces of assessment information representing positive assessment is two, in a case where the assessment of all of assessment information corresponding to a series of operations including a reference operation and an input of “hamburger,” assessment information corresponding to a series of operations including a reference operation and an input of “meat-stuffed peppers,” and assessment information corresponding to a series of operations including a reference operation and an input of “beef croquette” is positive, the behavior prediction unit 21b finally predicts the candidate action “cooking a meat dish using the home appliance 1” as a behavior of the subject user using the home appliance 1.
On the other hand, if there are a smaller number of pieces of assessment information representing positive assessment than the predetermined number, the behavior prediction unit 21b determines the candidate behavior to be a behavior for which suggestion information may not be presented to the subject user. In this case, the processes from S105 are not performed. The word “positive” will be described below.
The behavior prediction unit 21b transmits information about the candidate behavior predicted as a behavior of the subject user using the home appliance 1 to the suggestion information processing unit 21c after performing the behavior prediction process. On the other hand, if no specific action is detected (S103: NO), the behavior prediction unit 21b performs the process of S103 again.
After S104, the suggestion information processing unit 21c that has received the prediction result from the behavior prediction unit 21b performs suggestion information processing (S105). The suggestion information processing is processing to generate suggestion information such that the suggestion information is presented to the subject user by means of the subject communication device and to transmit the generated suggestion information to the subject communication device. In the example of the flowchart of
Here, “useful information” refers to information that enables, when the information is presented while a behavior is performed using the home appliance 1, the subject user to easily perform the behavior that matches his or her habits or preferences related to the use of the home appliance 1 or behavior of the subject user to be promoted. In the present embodiment, because the home appliance 1 is a microwave oven, for example, if either the first user or the second user preferably cooks a meat dish. the recipe for the meat dish is “useful information” for the user. Also, for example, if the home appliance 1 is a television, a list of television programs in the genre that either the first user or the second user preferentially watches is “useful information” for the user.
The suggestion information processing by the suggestion information processing unit 21c is performed as follows. First, the suggestion information processing unit 21c analyzes the content of assessment information corresponding to the suggestion information presented when a similar behavior to a behavior predicted by the behavior prediction unit 21b was performed in the past. Then, if the number of pieces of assessment information with positive content is greater than or equal to a predetermined value, the suggestion information processing unit 21c generates suggestion information and transmits the suggestion information to the first communication device 3. That is, even if the behavior prediction unit 21b predicts the behavior of the first user, in other words, the subject user, the suggestion information is not necessarily presented to the first user. As a result, the first user is not wastefully presented with suggestion information that is hard to feel useful, and the first communication device 3 can be operated and used smoothly. Note that the meaning of the word “positive” will be described later.
The suggestion information processing unit 21c does not transmit the suggestion information to the second communication device 4, in other words, to a communication device not serving as a subject communication device. As a result, because the suggestion information is not presented to the second user, in other words, the user who is not a subject user, the second user is not wastefully presented with the suggestion information that is little related to him or her, and the second communication device 4 can be operated and used smoothly.
After S105, the presentation unit 33 performs a suggestion information presentation process on the basis of the suggestion information received from suggestion information processing unit 21c via the third communication unit 30 (S106). S106 is an example of a suggestion information processing step. In the example of the “useful information” described above, if the behavior of the first user predicted by the behavior prediction unit 21b is cooking a meat dish, the presentation unit 33 generates an image representing the recipe for the meat dish and displays the image on a display screen. In addition, when the behavior of the first user predicted by the behavior prediction unit 21b is watching a television program, the presentation unit 33 generates an image representing a list of television programs in the genre that the first user preferentially watches and displays the image on the display screen.
After S106, the assessment information processing unit 31b performs an assessment information processing (S107). The assessment information processing is to generate assessment information by receiving, with the operation unit 32 or 42, an operation of inputting the assessment of the subject user with respect to the suggestion information presented by the presentation unit 33 or 43. In addition, the process includes a series of processes of transmitting the generated assessment information to the behavior prediction unit 21b via the third communication unit 30 or 40. In the example of the flowchart of.
For example, an image displayed as “GOOD/BAD” may be displayed on the display screen of the presentation unit 33. In this case, when the first user touches or hovers the portion of the display screen on which “GOOD” of the image is being displayed, assessment information (for example, a point with “+1”) representing positive assessment on the suggestion information presented by the presentation unit 33 is generated. “Positive” in the present specification refers to a case in which the subject user feels that the presented suggestion information was helpful or a good reference. On the other hand, “negative” refers to a case in which the subject user feels that the presented suggestion information was less helpful or the presentation hindered the operation or use of the subject communication device.
The behavior prediction unit 21b that has received the assessment information of the first user from the assessment information processing unit 31b via the second communication unit 20 and the second information management unit 21a accumulates, stores, and manages the received assessment information in a memory, which is not. illustrated. Note that the behavior prediction unit 21b does not necessarily need to accumulate, store, and manage the assessment information, and the second information management unit 21a, example, may accumulate, store, and manage the assessment information. Each of the processes from S101 to S107 described above is performed, and thereby the presentation of the suggestion information by information presentation system 100 is completed.
Next, a modified example of the information presentation system 100 according to an embodiment of the disclosure will be described using
For example, a first control device 11 of a home appliance 1 may be provided with the behavior prediction unit 21b and the suggestion information processing unit 21c. In other words, as illustrated in
In the case of the modified example illustrated in
For example, the behavior prediction unit 21b and the suggestion information processing unit 21c may be provided in each of the third control devices 31 and 41 of the first and second communication devices 3 and 4. In other words, as illustrated in
In the case of the modified example illustrated in
In other words, an information presentation system according to an aspect of the disclosure may include at least one home appliance having a communication function and a plurality of communication devices, and may be controlled by at least one control device that performs the behavior prediction processing and the suggestion information processing. The “plurality of communication devices” include a server, in addition to a terminal device such as a smart phone or a tablet terminal. Also, the “at least one control device” may be mounted in a home appliance or any one of the plurality of communication devices or may be mounted on neither a home appliance nor the plurality of communication devices.
Next, in the information presentation system 100 according to an embodiment of the disclosure, each of the presentation units 33 and 43 of the first and second communication devices 3 and 4 may be a speaker, which is not illustrated. Alternatively, either of the presentation units 33 and 43 may be a speaker and the other may be a display unit.
In this modified example, for example, third control devices 31 and 41 may include an uttered sentence generation unit, which is not illustrated, that receives suggestion information and generates an uttered sentence representing the content of the suggestion information, and the content of the uttered sentence generated by the uttered sentence generation unit may be output in the form of sound from the speaker served by the presentation unit 33 and/or 43. The above likewise applies to the information presentation systems 200 and 300 according to the modified examples of the embodiment of the disclosure.
In other words, the communication devices configuring the information presentation system according to an aspect of the disclosure may present, a subject user, suggestion information received from the control device that performs the behavior prediction processing and the suggestion information processing in the suggestion information presentation process using any method.
Next, in the information presentation system 100 according to the embodiment of the disclosure, the second control device 21 of the server 2, specifically the behavior prediction unit 21b of the second control device 21, may not perform the process of S103 (detection of specific operations) in the flowchart of
In other words, the information presentation system according to one aspect of the disclosure may present suggestion information to a subject user by performing at least the behavior prediction process and the suggestion information processing.
Next, in the information presentation system 100 according to the embodiment of the disclosure, the second control device 21 of the server 2, specifically the behavior prediction unit 21b of the second control device 21, may infer changes in a behavior of the subject user on the basis of the operation information and the operation history during the execution of the behavior prediction processing. In this modified example, the behavior prediction unit 21b predicts a behavior of the subject user using the home appliance 1 to improve a concern by matching the concern assumed to be the inferred change of the behavior.
Specifically, the behavior prediction unit 21b identifies the time or the like at which the subject user operated the home appliance 1 from the operation information and compares a plurality of reference operations in the operation history with the time or the like at which the reference operation has been performed. The behavior prediction unit 21b also identifies the period from the operation of the subject user from which the operation information was generated to the reference operation performed just before the operation.
For example, in a case where the operation time of the operation of the subject user from which the operation information was generated is earlier for a predetermined period of time or longer than the operation time of the plurality of reference operations, the behavior prediction unit 21b infers that the subject user has intentionally operated the home appliance 1 earlier than usual. Here, the memory of the behavior prediction unit. 21b or the second information management unit 21a stores the user's concerns in a data table format, and the behavior prediction unit 21b selects a concern reasonably supposed from a change of the inferred behavior of the subject user from the data table. The data table may be a data table listed with concerns common to the first user and the second user or may be a data table listed with different concerns for the first user and the second user.
A “concern” refers to a matter which the first user and the second user are troubled with on their daily lives and can be improved by the users' own behaviors. Concerns can include “time excess/time shortage,” “hot/cold,” “fatigue,” “obesity,” “household chore,” and the like.
In a case where the inputs of an operation of the subject user and a reference operation from which the operation information was generated are “oven,” “600 W,” and “heating time: approximately 2 to 3 minutes,” the behavior prediction unit 21b supposes that the reason that the subject user intentionally operated the home appliance 1 earlier than usual is time excess of the subject user and selects “time excess” from the data table.
Then, the behavior prediction unit 21b predicts a behavior of using the home appliance 1 to solve the concern “time excess.” In this case, the behavior prediction unit 21b predicts that the subject user may perform cooking for a long period of time using the home appliance 1 because a long cooking time can be ensured. The suggestion information processing unit 21c that has received the result of the prediction generates a list cooking recipes that take a long period of time, for example, as suggestion information.
Also, for example, in a case where the period from the operation of the subject user from which the operation information was generated to the reference operation performed just before the operation is longer than or equal to a predetermined period of time, the behavior prediction unit 21b infers that the subject user intentionally has not performed a behavior using the home appliance 1 for a period of time. In the example of the inputs “oven,” “600 W,” and “heating time: approximately 2 to 3 minutes,” the behavior prediction unit 21b supposes that the reason that the subject user intentionally has not performed cooking using the home appliance 1 for a period of time is that the subject user feels cooking annoying and selects “household chore” from the data table.
Then, the behavior prediction unit 21b predicts a behavior of using the home appliance 1 to solve the concern “household chore.” In this case, the behavior prediction unit 21b predicts that the subject user may use the home appliance 1 to cook a simple cuisine because the subject user can cook a simple cuisine without feeling cooking annoying. The suggestion information processing unit 21c that has received the result of the prediction generates a list of recipes of cuisines, for example, easy-to-cook cuisines, as suggestion information. The behavior prediction processing of the behavior prediction unit 21b and the suggestion information processing of the suggestion information processing unit 21c described above can also be applied to the information presentation systems 200 and 300 according he modified examples of the embodiment of the disclosure.
A control block (in particular, the behavior prediction unit 21b and the suggestion information processing unit 21c) of the second control device 21 according to the embodiment may be realized by a logic circuit (hardware) formed of an integrated circuit (IC chip) and the like, or by software.
In the latter case, the second control device 21 includes a computer that executes commands of a program that is software for realizing functions. The computer includes, for example, at least one processor (control device) and includes at least one computer-readable recording medium storing the program. Then, the computer achieves the objective of the disclosure due to the processor reading the program from the recording medium and executing the program.
For example, a central processing unit (CPU) can be used as the processor. As the recording medium, a “non-transitory tangible medium,” for example, a tape, a disk, a card, a semiconductor memory, and a programmable logic circuit may be used, in addition to a read only memory (ROM). In addition, a random access memory (RAM) in which the program is loaded may be further included. Further, the program may be supplied to the computer via any transmission medium (a communication network, a broadcast wave, or the like) capable of transmitting the program. Note that an aspect of the disclosure may be implemented in a form of data signals embedded in a carrier wave, which is embodied by electronic transmission of the program.
A control device (the second control device 21) according to a first aspect of the disclosure is a control device configured to control an information presentation system (100, 200, 300) including at least one home appliance (1) having a communication function and a plurality of communication devices (the first communication device 3 and the second communication device 4), the control device including a behavior prediction unit (21b) configured to perform behavior prediction processing to predict a behavior using the at least one home appliance of a subject user who is a user of one of the plurality of communication devices operating the at least, one home appliance on the basis of operation information representing the operation content of an operation received by the at least one home appliance and an operation history of the at least one home appliance accumulated for each user of the plurality of communication devices, and a suggestion information processing unit (21c) configured to perform suggestion information processing to generate suggestion information useful for the subject user to performs the behavior predicted by the behavior prediction unit such that the suggestion information is presented to the subject user using a subject communication device
