In Step S1705, the control unit 205 reads a record of UID=i from the private information list 241, and describes the read record into the advertisement distribution destination information list 246.
In Step S1706, the control unit 205 judges whether any unprocessed UID remains in the device operation information list 244. When any unprocessed UID does not remain (Step S1706: NO), the processing ends. When any unprocessed UID remains (Step S1706: YES), the control unit 205 proceeds to Step S1707.
In Step S1707, the control unit 205 assigns the remaining unprocessed UID to the variable i, and then proceeds to Step S1702.
Through the above processing, it is possible to extract, as an advertisement distribution destination, a user who is estimated to have wheat allergy based on that the user satisfies the following conditions: although the user owns an automatic bread baker having the wheat flour bread making function, the user has not used the wheat flour bread making function; although the user owns a microwave oven having the okonomiyaki grill function for making okonomiyaki whose raw material is wheat flour, the user has not used the okonomiyaki grill function; and odor of okonomiyaki has not been detected by an air conditioner equipped with an odor sensor owned by the user.
The above explanation has been given on the case where a user who does not prefer wheat flour as a specific material is extracted as an advertisement distribution destination, and a millet flour cake that is made using an alternative (millet flour) to the specific material is determined as an advertisement target product. However, the advertisement target product is not limited to an alternative to the specific material, and any product for avoiding the specific material. In the case where the specific material is for example pollen, the advertisement target product may be a pollen protection mask, and a user with pollen allergy may be extracted as an advertisement distribution destination.
The following explains the advertisement distribution destination information generation processing relating to pollen allergy, with reference to
Processing in Steps S1801 and S1804 to S1806 shown in
In Step S1802, the control unit 205 included in the management server 10 judges whether the device operation information list 244 includes a record in which UID=i, MID=4, time information indicating any of March to May, and device generation information of “ventilation” are described. When the record is described (Step S1802: YES), the control unit 205 proceeds to Step S1805. When the record is not described (Step S1802: NO), the control unit 205 proceeds to Step S1803. The processing in Step S1802 is processing of making a judgment on a condition indicated by condition information described in an extraction rule 921 included in the rule information 902.
In Step S1803, the control unit 205 included in the management server 10 judges whether the device operation information list 244 includes a predetermined number or more of records in which UID=i, MID=4, time information indicating each of January, February, June to December, and device generation information of “ventilation” are described. When the predetermined number or more of records are described (Step S1803: YES), the control unit 205 proceeds to Step S1804. When the predetermined number or more of records are not described (Step S1803: NO), the control unit 205 proceeds to Step S1805. The processing in Step S1803 is processing of making a judgment on a condition indicated by condition information described in an extraction rule 922 included in the rule information 901.
Through the above processing, it is possible to extract, as an advertisement distribution destination, a user who is estimated to have pollen allergy based on that the user prevents intrusion of pollen into a house by not using a ventilating fan for a period in a single year in which an amount of pollen is large (March to May), and uses the ventilating fan for ventilation for a remaining period in the single year.
The following explains the advertisement distribution processing performed by the management server 10 and the purchase terminal 40, with reference to
In Step S1901, the advertisement distribution processing unit 223 included in the management server 10 transmits advertisement information to the purchase terminal 40. The advertisement information is information for advertising an advertisement target product to a user. The advertisement information for example includes the advertisement image 1201. Here, one-to-one association between users and the purchase terminals 40 is described in the purchase terminal list 602. The control unit 305 included in the purchase terminal 40 receives the advertisement information.
In Step S1921, the control unit 305 included in the purchase terminal 40 generates an advertisement image based on the received advertisement information, and causes the display unit 306 to display the generated advertisement image.
In Step S1922, with reference to the advertisement image displayed on the display unit 306, the user determines whether to purchase an advertisement target product appearing on the advertisement image. When determining to purchase the advertisement target product, the user inputs a purchase instruction via the input unit 301 included in the purchase terminal 40. This purchase instruction is input for example by the user pressing the “Purchase” button appearing on the advertisement image. On the other hand, when determining not to purchase the advertisement target product, the user inputs a no-purchase instruction via the input unit 301 included in the purchase terminal 40. This no-purchase instruction is input for example by the user pressing “Not Purchase” button appearing on the advertisement image. The input unit 301 notifies the control unit 305 of the input purchase instruction or no-purchase instruction.
When receiving the no-purchase instruction (Step S1922: NO), the control unit 305 transmits purchase result information indicating “No intention to purchase” to the management server 10 (Step: S1923), and ends the processing. On the other hand, when receiving the purchase instruction (Step S1922: YES), the control unit 305 transmits purchase result information indicating “Intention to purchase” to the management server 10 (Step S1924).
Here, the “Purchase” button appearing on the advertisement image 1201 has a URL of a purchase website that is set as a link. When the “Purchase” button is pressed, a web browser of the device is redirected to the website indicated by the URL (Step S1925), and the display unit 306 displays a home page image of the website.
In Step S1926, the user performs purchase processing. Processing of purchasing a product on a purchase website is known, and accordingly explanation thereof is omitted.
The following details the rule information update processing in Step S1407. Upon receiving purchase result information indicating “No intention to purchase” form the purchase terminal 40, the rule information update unit 224 included in the management server 10 estimates that rule information has an error, and performs the rule information update processing.
In the case where there is device generation information: (a) that is collected from a device belonging to a model ID described in the rule information; and (b) that indicates a function other than a function to be detected in any extraction rule included in the rule information, the rule information is updated by adding an extraction rule including condition information describing a condition that “the function indicated by the device generation information has not been used” to the rule information.
The following explains the case where when purchase result information with respect to a user having the user ID “UID1” indicates “No intention to purchase”, the model information list 242 is as shown in
In this case, device generation information that satisfies the above conditions (a) and (b) indicates the pasta boiling function. A user who has used the pasta boiling function is estimated not to purchase a product for users with wheat allergy. Accordingly as shown in
Although the embodiment of the advertisement distribution system relating to the present invention has been explained, the exemplified advertisement distribution system may be modified as follows. The present invention is of course not limited to the advertisement distribution system exactly as explained in the above embodiment.
(1) In the above embodiment, the management server 10 detects an unused function included in each device, and selects an advertisement distribution destination by checking the detected unused function with rule information. However, the server 10 only needs to select a user appropriate as an advertisement distribution destination based on the detected unused function.
For example, the server 10 may not need to use rule information. Specifically, with respect to each of functions included in each device, the management server 10 beforehand makes an association between the function and an advertisement to be transmitted in the case where the function is judged to an unused function. In the case where an unused function is detected with respect to a device and an advertisement that is associated with a function judged to the unused function is an advertisement of an advertisement target product, a user who owns the device may be selected as an advertisement distribution destination.
(2) In the above embodiment, the explanation has been given with use of the pieces of rule information 901 and 902 as the rule information for extracting a user who is appropriate for an advertisement. However, these pieces of rule information are just examples. However, the rule information only needs to be configured such that the management server 10 extracts a user who is appropriate for an advertisement by comparing a detected unused function with the rule information. Also, in the above embodiment, examples of a user who is appropriate for an advertisement include a user with wheat allergy and a user with pollen allergy. However, a user who is appropriate for an advertisement is not limited to these users.
Also, in the above embodiment, the rule information is composed of two or three extraction rules. However, the rule information only needs to be configured such that a user who is appropriate for an advertisement is extracted. The rule information may be for example composed of one extraction rule, or four or more extraction rules.
Also, the rule information does not need to be composed of only a condition to be satisfied by an unused function. Alternatively, the rule information may be composed of a combination of a condition to be satisfied by an unused function and a condition to be satisfied by a used function. For example, the rule information 901 is composed of a combination of the extraction rules 911 and 912, which are conditions to be satisfied by an unused function, and the extraction rule 913, which is a condition (odor of okonomiyaki has not been sensed) to be satisfied by a used function (the odor sensing function).
Also, the rule information may includes, as an extraction rule, a condition to be satisfied by a material that is extracted based on detection results and measurement results that are respectively obtained through execution of a detection function and a measurement function included in the device, in addition to a condition to be satisfied by an unused function. The extraction rule here for example indicates that “Unused material is wheat flour”.
Also, the management server 10 may collect, as device generation information of each device, measurement results obtained through execution of a measurement function such as temperature, humidity, and luminous intensity around the device, an amount of oil used for cooking, sensing results obtained through execution of a taste sensing function, and so on, in addition to the sensing results obtained through execution of the odor sensing function. Also, the management server 10 may collect, from a device relating to cooking, detection results of a used ingredient, weight measurement results of a dish and a food product, and so on.
(3) In the above embodiment, the management server 10 detects, as an unused function, a function which has not been used at all in each device. Alternatively, a function that has been used at an extremely lower frequency than other functions may be detected as an unused function. In this case, it is possible to detect, as an unused function, a function that can be estimated to have been used by a user only a small number of times out of necessity but not to be positively hoped by the user to be used.
(4) In the above embodiment, the management server 10 detects, as an unused function, a function which has not been used at all in a single year. Alternatively, a function that has not been used only for a certain period in the single year may be detected as an unused function. In this case, it is possible to extract, an advertisement distribution destination, a user who is appropriate for an advertisement for a particular period in the single year such as a particular season.
Further alternatively, a function that has not been used only for a particular period in a single day may be detected as an unused function. In this case, it is possible to extract, an advertisement distribution destination, a user who is appropriate for an advertisement for a particular period in the single day such as an evening period. For example, in the case where a user who has not used a cooking function in the in the evening, the user is estimated to frequently eat out. Accordingly, it is possible to generate advertisement information on a restaurant for eating out and transmit the advertisement information to the user.
(5) In the above embodiment, the management server 10 detects an unused function with use of all pieces of device operation information which are collected from each device. However, all the collected pieces of device operation information may not need to be used. Alternatively, the unused function may be detected with use of only pieces of device operation information that have been collected for the most recent predetermined period for example. In this case, it is possible to select an advertisement distribution destination in reflection of the most recent preference of a user.
Assume a case, for example, where an advertisement distribution destination is extracted with use of pieces of device operation information that have been collected for the most recent one month. In this case, it is possible to exclude, from an advertisement distribution destination, a user who had been a certain allergy one month before but has got over the allergy for the most recent one month.
(6) In the above embodiment, the management server 10 extracts a user with wheat allergy. However, a user to be extracted is not limited to this. Alternatively, a user with other allergy such as egg allergy and dairy allergy may be extracted. Further alternatively, a user may be extracted who cannot take a specific food for reasons of thought, religion, and so on, irrespective of whether the user is allergic to a specific material. Yet alternatively, a user may be extracted who avoids a specific material (for example, oil) for reasons of calorie concern, diseases, and so on, irrespective of whether the user is allergic to a specific material.
(7) In the above embodiment, the management server 10 detects an unused function with use of pieces of device operation information collected from each device. Alternatively, the management server 10 may detect a material that has not been used in execution of the function (hereinafter, referred to as unused material) with use of the collected pieces of device operation information, and determines the unused material as a specific material.
The following explains an example of procedure of detecting an unused material. The management server 10 stores therein beforehand a material information list shown in
First, the control unit 205 included in the management server 10 extracts an unused function in the procedure explained in the above embodiment (procedure 1). Next, the control unit 205 refers to the material information list to extract one or more materials that are associated with the extracted unused function (procedure 2). Finally, the control unit 205 extracts, as a specific material, a material that is not associated with another function that has been executed by a device among the extracted materials (procedure 3).
Here, the procedures 1 to 3 are supplemented with use of a specific example. Assume a case, for example, where the wheat flour bread making function is extracted as an unused function in the procedure 1. Also, collected pieces of device operation information are assumed to include respective pieces of device generation information indicating the rice flour bread making function and the mochi making function as executed functions. In this case, materials including wheat flour, salt, sugar, butter, . . . are extracted in the procedure 2, as materials that are associated with the unused function extracted in the procedure 1. Here, materials including salt, sugar, butter, . . . are associated with the rice flour bread making function and/or the mochi making function among the materials including wheat flour, salt, sugar, butter, . . . which are extracted in the procedure 2. This results in that the control unit 205 extracts wheat flour as the unused material in the procedure 3.
(8) In the above Modification (7), a material that has not been used at all is detected as an unused material. Alternatively, a material whose amount that has been used is a predetermined amount or less, or a material that has been used at a predetermined frequency or less may be detected as an unused material.
The following explains an example where a material, specifically salt, whose amount that has been used is a predetermined amount or less is detected as an unused material. As shown in
First, with respect to pieces of device operation information that have been collected from a device for the most recent one month, the control unit 205 included in the management server 10 judges whether respective pieces of device generation information included in the collected pieces of device operation information are each described in the point table. When judging the piece of device generation information is described in the point table, the control unit 205 adds the use point that is associated with the piece of device generation information in the point table. In the case where the condition described in the rule information shown in
Then, in the case where the unused material (salt in the present modification) is determined as a specific material, the management server 10 transmits an advertisement of an advertisement target product that is targeted for users who do not prefer this specific material to a user who owns the device with respect to which salt is detected as the unused material.
(9) In the above embodiment and modifications, the explanation has been given on the examples where a user with food allergy and a user with pollen allergy are extracted. However, it is only necessary to extract a user with allergy to a specific material. For example, the specific material may be a specific material used for clothes (such as chemical fiber). In this case, the management server 10 judges whether pieces of device operation information that have been collected from a washing machine that is one of devices owned by a user indicate a function to be used for clothes made of a specific material (such as a washing function and a drying function in accordance with a washing procedure dedicated for the specific material). When judging that the collected pieces of device operation information do not indicate the function to be used for clothes made of the specific material, the management server 10 judges that the user who owns the washing machine is allergic to the specific material.
(10) In the above embodiment, an advertisement of a product is distributed to an advertisement distribution destination. Alternatively, an advertisement of service may be distributed. For example, in the case where a user who has not used a function of making dishes using oil is extracted as an advertisement distribution destination, an advertisement of a food item made using little oil as an advertisement target product may be distributed to the user. Alternatively, an advertisement of a restaurant or an accommodation that serves dishes made using little oil as an advertisement target service may be distributed to the user.
(11) In the above embodiment, the management server 10 stores therein pieces of device operation information separately for each device. However, it is only necessary to store the pieces of device operation information such that an unused function is detected. For example, respective pieces of device operation information received from a plurality of device that belong to the same model may be stored as pieces of device operation information of one device without distinction between the devices.
(12) In the above embodiment, an advertisement distribution destination is selected in units of users. Alternatively, an advertisement distribution destination may be selected in units of groups such as families and corporations. In this case, a list of information on a representative of a group such as a family and a corporation may be used, instead of the above private information list.
(13) In the above embodiment, a user, who shows intention to purchase a product, purchases the product on a purchase website indicated by a URL set in an advertisement image displayed on a purchase terminal owned by the user. However, the user only needs to be able to purchase the product. For example, the management server 10 may function as the purchase website.
(14) In the above embodiment, rule information is updated as follows. In the case where there is device generation information: (a) that is collected from a device belonging to a model ID described in the rule information; and (b) that indicates a function other than a function to be detected in any extraction rule included in the rule information, the rule information is updated by adding an extraction rule including condition information describing a condition that “the function indicated by the device generation information has not been used” to the rule information. However, this update procedure is just as an example. Alternatively, the rule information may be updated by another update procedure according to which the rule information is updated with use of device generation information and an unused function, and the updated extraction rule is used to increase a possibility that the extracted user is appropriate as an advertisement distribution destination.
(15) In the above embodiment, each device is disposed inside a home of a user who owns the device. However, disposition location of the device does not need to be limited, and the device only needs to be capable of communicating with the management server 10. Also, communication between the device and the management server 10 does not necessarily need to be performed via the router 50, and alternatively may be performed directly.
(16) In the above embodiment, the explanation has been given on the example where the first device 30-1 to the third device 30-3 are respectively an automatic bread baker, a microwave oven, and an air conditioner equipped with an odor sensor, and the fourth device 30-4 and the fifth device 30-5 are each a ventilating fan. However, these devices each only need to be a home appliance that is capable of communicating with the management server 10 and transmitting device generation information to the management server 10. The first device 30-1 to the fifth device 30-5 each may be for example, instead of the above home appliances, a smartphone, a ceiling light, a television, a BD player, a facsimile machine, an air conditioner, an oven stove, a body composition analyzer, a rice cooker, a washing machine, a recording/playback device for video and audio, a vacuum cleaner, an air cleaner, a printer, an electric pot, a coffee maker, a phone, a mobile phone, and an alarm clock. Note that the function execution units 304 for achieving the functions of the respective devices differ in configuration between these devices.
(17) In the above embodiment, the management server 10 is embodied as one computer. However, the management server 10 only needs to be configured to achieve the functions explained on the management server 10 in the above embodiment. For example, the management server 10 may be embodied as a cloud that is composed of a plurality of computers, storage devices, and so on.
(18) It is possible to record the following control program in a recording medium or distribute the control program via various types of communication paths. The control program is composed of program codes in a machine language or a high-level language for causing the respective processors included in the management server 10 and the first device 30-1 to the fifth device 30-5, and various types of circuits that are connected to the processors to perform the processing, which is explained in the above embodiment, including the device operation information collection processing, the advice information display processing, the advertisement distribution target information acquisition processing, the rule information acquisition processing, the advertisement distribution destination information generation processing, the advertisement distribution processing, and the rule information update processing. Examples of such a recording medium include an IC card, a hard disk, an optical disc, a flexible disc, a ROM, and a flash memory. The distributed control program is stored in a memory or the like that is readable by a processor for use, and the functions explained in the above embodiment are achieved by the processor executing the control program. Instead of executing the control program, the processor may execute the control program after compile or use an interpreter.
(19) The following functional elements explained in the above embodiment may be embodied as a circuit for achieving the function thereof, or may be embodied through execution of a program by one or more processors, such as the input unit 201, the communication unit 202, the storage unit 203, the clock unit 204, the control unit 205, the advice information generation unit 221, the advertisement distribution destination information generation unit 222, the advertisement distribution processing unit 223, the rule information update unit 224, the information processing unit 225, the input unit 301, the communication unit 302, the storage unit 303, the function execution unit 304, the control unit 305, and the display unit 306.
Note that the above functional elements may be representatively embodied as an LSI that is an integrated circuit. These functional elements may be separately integrated into a single chip, or integrated into a single chip including part or all of the functional elements. Furthermore, the LSI may be called an IC, a system LSI, a super LSI, and an ultra LSI, depending on the integration degree. A method of circuit integration is not limited to LSIs, and may be realized by a dedicated circuit or a general processor. Furthermore, it may be possible to use an FPGA (Field Programmable Gate Array) programmable after manufacturing LSIs or a reconfigurable processor in which connection and setting of a circuit cell inside an LSI is reconfigurable after manufacturing LSIs. Furthermore, when a new technology for forming integrated circuits that replaces LSIs becomes available as a result of progress in semiconductor technology or semiconductor-derived technologies, functional blocks may of course be integrated using such technology. One possibility lies in adaptation of biotechnology.
(20) The present invention may be any partial combination of the above embodiment and modifications.
The following further describes configuration of an advertisement distribution method and an advertisement distribution system as one embodiment of the present invention, and modifications and effects thereof.
(1) One aspect of the present invention provides an advertisement distribution method that is executed by an advertisement distribution system that distributes an advertisement of a product to a user among a plurality of users who is expected to purchase the product, the advertisement distribution method comprising: a collecting step of collecting, from each of one or more of home appliances that are owned by each of the users, one or more pieces of execution information each indicating a function that has been executed by the home appliance; a detecting step of, with respect to each of the users, detecting an unused function that has not been used in each of the home appliances owned by the user by analyzing the pieces of execution information collected from the home appliance and functions included in the home appliance; and a transmitting step of extracting the user who is expected to purchase the product based on a result of the detection performed by the detection step, and transmitting the advertisement to one or more of the home appliances owned by the extracted user.
According to this configuration, it is possible to determine an advertisement distribution destination of a product that has a low direct relevance to pieces of execution information collected from each home appliance. Note the execution information is equivalent to the device generation information in the above embodiment.
(2) Also, the product may be targeted for users who do not prefer a specific material, and in the transmitting step, with respect to each of the home appliances owned by each of the users, the user who owns the device with respect to which the unused function using the specific material is not detected may be extracted as the user who is expected to purchase the product.
According to this configuration, it is possible to extract, as the advertisement distribution destination of the product that has a low direct relevance to the pieces of execution information collected from each of the home appliances, a user who does not prefer a specific material.
(3) Also, the advertisement distribution method may further comprise a displaying step of displaying that the home appliance with respect to which the unused function is detected includes the unused function, on one or more of the home appliances owned by the user who owns the home appliance with respect to which the unused function is detected.
According to this configuration, with respect to a function included in a home appliance detected as an unused function, it is possible to increase a possibility that the function has not been used not because a user has not recognized that the function is included in the home appliance but because the user has hoped not to use the function despite of that the user has recognized that the function is included in the home appliance.
(4) Also, the product may be useful for a particular period in a single year, and in the detecting step, a function that has not been used for the particular period is detected as the unused function.
According to this configuration, it is possible to extract a user who is appropriate for an advertisement of a product that is useful for a specific period in a single year such as seasonal goods.
(5) Also, in the detecting step, a function indicated by a predetermined number or less of pieces of execution information may be detected as the unused function.
According to this configuration, it is possible to detect, as an unused function, even a function that has been used by a user at a low frequency out of necessity but is not positively hoped by the user to be used. This allows to add such a user to an extraction target, thereby more appropriately extracting a user who do not prefer a specific material.
(6) Also, in the detecting step, the pieces of execution information that have been collected for a last predetermined period may be used.
According to this configuration, it is possible to more appropriately extract a user who is estimated to purchase a product among a plurality of users, based on the user's last operations made on a home appliance owned by the user.
(7) Also, the product may be targeted for users who do not prefer a specific material, and in the transmitting step, the user who has used the specific material at a low frequency may be extracted based on the unused function as the user who is expected to purchase the product.
According to this configuration, it is possible to add, as an extraction target, even a user who has used a specific material at a low frequency out of necessity but does not positively hope to use the specific material. This allows to more appropriately extract such a user who does not prefer the specific material.
(8) One aspect of the present invention provides an advertisement distribution system that distributes an advertisement of a product to a user among a plurality of users who is expected to purchase the product, and includes a server and one or more home appliances that are owned by each of the users, wherein the server comprises: a collection unit configured to collect, from each of one or more of home appliances that are owned by each of the users, one or more pieces of execution information each indicating a function that has been executed by the home appliance; a detection unit configured to, with respect to each of the users, detect an unused function that has not been used in each of the home appliances owned by the user by analyzing the pieces of execution information collected from the home appliance and functions included in the home appliance; and a transmission unit configured to extract the user who is expected to purchase the product based on a result of the detection performed by the detection step, and transmit the advertisement to one or more of the home appliances owned by the extracted user.
According to this configuration, it is possible to determine an advertisement distribution destination of a product that has a low direct relevance to pieces of execution information collected from each home appliance.
The advertisement distribution method relating to the embodiment of the present invention allows to extract an advertisement distribution destination of a product that has a low direct relevance to pieces of execution information collected from each home appliance. Therefore, the advertisement distribution method is suitable for a system for selecting a more number of appropriate advertisement distribution destinations and distributing an advertisement to the selected advertisement distribution destinations.
