  According to the above-described conventional technology, for example, the user evaluation of the facility is the user's answer to a predetermined questionnaire or the like! It has been performed by using a system that can reflect the user's will and the like represented by buttons and word-of-mouth points. However, in the user evaluation obtained by the input method as described above, it may be difficult to say that the evaluation reflects the true feeling of the user due to, for example, an input error of the user. In addition, there is a case where a user inputs with a relationship or inertia, or an improper act of impersonating an evaluator and giving a high evaluation. If the database reflecting the user evaluation taking the user's subjectivity into account is used in this way, there may be a situation in which the expectation of the visitor who visited the facility with reference to the user evaluation is betrayed.

  In view of such a situation, the present inventor has intensively studied to create a map database that reflects true information on components such as facilities while eliminating the user's subjective elements as much as possible. As a result, it is possible to solve the above-mentioned problem by specifying the status of the component based on information obtained from the wearable device and reflecting the status of the specified component in the map database as information related to the component. I came up with it.

The present invention has been made in view of the above-mentioned problems, and the first aspect is defined as follows. That is,
A receiving unit for receiving an information set including wearable device-derived information and position information;
An extraction unit for extracting an information set related to the component based on the position information of the information set and the position information of the component of the predetermined map;
Based on the wearable device-derived information of the extracted information set, a specifying unit that specifies the status of the component for each component,
A writing unit that writes the status of the identified component into a map database as map data related to the component;
A map database creation device comprising:

  According to the map database creation device of the first aspect thus defined, first, an information set including wearable device-derived information and position information is accepted. And about the component of the map corresponding to this positional information, the condition of this component is specified based on the said wearable device origin information, and the condition of this specified component is reflected in a map database. According to this map database creation device, since the situation of the component is specified based on information that does not allow the user's subjectivity to be called wearable device-derived information, the map database reflecting the true situation of the component Can be created.

Here, the wearable device-derived information may be information obtained from the wearable device, and may be, for example, biological information (third aspect). The biological information is information related to the user's biological body, and examples thereof include pulse, heartbeat, breathing, sweating, blood pressure, electroencephalogram, body temperature, vocalization, head movement, pupil, and eye movement. Another example of the wearable device-derived information is environmental information. The environmental information is information related to the environment in or around the components of the facility, and examples thereof include noise, smell, heat / coldness, brightness, and ultraviolet rays.
The said component is the target object drawn on a map, for example, a facility, a road, and an intersection are mentioned. The status of the component means the state of the user when the component is present. For example, when the above component is a facility, “relax”, “fun”, “noisy”, etc. can be mentioned, and when the above component is a road or an intersection, “close incident” can be mentioned. it can. The status of the component may be obtained by giving a degree to the user state such as “relax” or “near hat” based on the wearable device-derived information.

The second aspect of the present invention is defined as follows. That is,
In the map database creation device defined in the first aspect, comprising a comparison unit that compares the status of the identified component and other map data related to the component in the map database,
The writing unit performs the writing based on the comparison result.

  According to the map database creation device of the second aspect defined as described above, when the situation of the specified component and the other map data related to the component are compared with each other, they match. On the other hand, when the above writing is executed and both are different, the writing can be canceled. According to such an apparatus, for example, due to noise of wearable device-derived information or the like, or due to a mismatch in position information between the wearable device-derived information and the map component, the status of the component is determined. If it is specified by mistake, writing to the map database can be avoided, so that the accuracy of creating the map database can be improved.

The fourth aspect of the present invention is defined as follows. That is,
In the map database creation device defined in the third aspect, a filter unit that filters the extracted information set based on a change in biological information of the information set while a wearable device user is present in the component. Prepare.
According to the map database creation apparatus of the 4th situation prescribed | regulated in this way, the change of the biometric information of a wearable device user while existing in a component can be considered.
The filter unit can filter the information set under a predetermined condition in consideration of changes in biological information. For example, filtering can be performed by setting only the information set satisfying the predetermined condition as the specific target of the situation.

  The change in the biological information can be considered by various methods such as a change amount, a change rate, and a change maintenance time. The greater the change amount, the greater the change rate, and the longer the change maintenance time, the more reliable the situation specified based on the biological information. As a method of considering the amount of change when the biological information is a pulse, for example, based on the pulse rate when a wearable device user enters a certain facility and the pulse rate after a certain time has passed in the facility The difference is set as a change amount, and when the change amount is equal to or greater than a predetermined threshold, the biological information can be set as the specific target of the situation. In addition, as a method of considering the rate of change, for example, in the above-described user's pulse, when the absolute value of the amount of change in the pulse rate per unit time from the time of entering a certain facility to the time when the pulse is stable is greater than or equal to a predetermined threshold value The biological information can be the specific target of the situation. This rate of change can be paraphrased as the rate of change of biological information. In addition, regarding the method of considering the maintenance time of the change, in the pulse of the user, from the time when the pulse changed and started to stabilize (or from the start of change), based on the time that the pulse stable state was sustained, When the maintenance time is equal to or longer than a predetermined threshold, the biological information can be set as the specific target of the situation. The filter unit may be based on one of the changes in the biological information, or may be filtered by combining two or more changes in the biological information.

(A) is an example of map data relating to components stored in the map database 5, and (B) is a diagram illustrating an example of a situation expected corresponding to a genre stored in the genre information database 35. FIG. It is a block diagram which shows the structure of the map database production apparatus 41 of other embodiment of this invention. It is a block diagram which shows the hardware constitutions of the map database creation apparatus 21 of other embodiment of this invention.

A map database creation device according to an embodiment of the present invention will be described.
FIG. 1 shows a schematic configuration of the map database creation device 1.
As shown in FIG. 1, the map database creation device 1 includes a map database 5, a receiving unit 7, an extracting unit 9, a specifying unit 11, and a writing unit 13. Further, the map database creation device 1 creates a map database using information obtained by the wearable device 3.

  The wearable device 3 is a device that can be worn by the user, and examples thereof include a wristwatch type, a spectacle type, and a head-mounted type device. The device can acquire various types of information. Examples of the acquired information include biological information of a wearable device user and environmental information of a place where the user exists. Examples of the biological information include pulse, heartbeat, breathing, sweating, blood pressure, electroencephalogram, body temperature, vocalization, head movement, pupil, and eye movement. In addition, the environmental information includes noise, smell, hot and cold, brightness, and the like. In the present specification, the information acquired by the wearable device 3 may hereinafter be described as wearable device-derived information and WD-derived information. Such WD-derived information is acquired and stored together with the position information from which the WD-derived information is acquired. Further, time information may be associated with these pieces of information.

The map database 5 stores various map data related to components for drawing on a map. For example, the name and position information of the component are stored as map data related to the component. In addition, attribute information such as a genre may be stored as the map data. Examples of the constituent elements include facilities, roads, and intersections.
The receiving unit 7 receives from the wearable device 3 an information set including WD-derived information and position information corresponding to the WD-derived information. The accepting method can be performed from the wearable device 3 through a wireless network or wired.

The extracting unit 9 refers to the map database 5 and the receiving unit 7, the positional information of the received information set, and the constituent elements stored in the map database 5 and determined in advance. Based on the position information, an information set related to the component is extracted. The extraction unit 9 may extract one information set corresponding to the position information, or may extract two or more information sets.
Based on the WD-derived information of the information set extracted by the extraction unit 9, the specification unit 11 specifies the status of the component for each component. The specific method is not particularly limited, and is “relaxed” when the pulse is below a predetermined value, “nearly closed” when the heartbeat is above a predetermined value, and “noisy” when the noise value is above a predetermined value. Environment "and the like.

  The writing unit 13 writes the status of the component specified by the specifying unit 11 in the map database as map data related to the component. For example, the writing unit 13 can perform the writing when a predetermined number or more of the same situation is specified for one component as a result of the specifying. In addition, when the status of the component specified by the device 1 has already been written in the map database 3, the writing unit 13 can function as follows. If the situation specified based on the new information from the wearable device 3 is the same as the situation already written, the writing unit 13 counts the specified number of times and combines the number of times. The evaluation value may be increased according to the number of times. In addition, if the situation specified based on the new information is different from the situation already written, the situation specified based on the new information may be written together, or the situation already written It can be written instead.

An example of the operation of the map database creation device 1 shown in FIG. 1 will be described with reference to FIG.
The following example demonstrates the case where a component is made into an intersection and WD origin information is made into biometric information.
In step 1, the receiving unit 7 receives an information set (WD-derived information and position information) from the wearable device 3.
In step 3, the extraction unit 9 is a component stored in the map database 5 from the information set extracted in step 1, and is associated with position information corresponding to the position information of the predetermined component. Extract information set. In this example, the component is an intersection X and has position information Px. The extracted information set is information set 1 (WD1, P1) having position information P1 corresponding to Px.

In step 5, the specifying unit 11 specifies the situation of the intersection X based on the WD-derived information (WD1) of the information set 1 extracted in step 3. In this example, the WD-derived information is a heart rate. That is, when the heart rate (WD1) of the information set 1 extracted in step 3 is equal to or greater than a value (first threshold) that is an index of a tight state (near-miss state) (step 7: Yes), the situation Is identified as a “near-miss state” (step 9), and the process proceeds to step 11.
In step 11, the writing unit 13 writes the situation specified in step 9, that is, “near-miss” state, as map data of the intersection X in the map database. That is, a map database is created in which the intersection name, location information, and map data of “near-missed state” are associated with the intersection X.

  In addition to the above example, a map database can be created by specifying the situation in the library using the component as a library and the WD-derived information as environmental information. In this case, based on the noise value as the environmental information, information such as “quiet environment” or “noisy environment” can be written in the map database as map data.

FIG. 3 shows a map database creation device 21 according to another embodiment. 3, the same elements as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is partially omitted.
FIG. 3 shows a map database creation device 21 that can avoid writing the situation in the map database when the situation of the identified component is determined to be invalid. That is, the apparatus 21 further includes a comparison unit 23 in the apparatus 1 shown in FIG. 1 and includes a writing unit 25 instead of the writing unit 13.
In this example, in the map database 5, in addition to the name and position information of the component, attribute information such as a genre of the component is stored as the map data, and the genre of the component includes the genre. Is associated with the expected situation. For example, when the constituent element is a facility, examples of the genre include “restaurant”, “massage store”, and “haunted house”. In addition, the situations expected for the above genre include “delicious”, “bright”, “fun” for the genre “restaurant”, “relaxed”, “comfortable”, “sleepy” for “massage store” “Haunted house”, “Scared”, “Sounding” and the like. An example of map data stored in the map database 5 is shown in FIG.

The comparison unit 23 refers to the map database 5 and the specifying unit 11 to compare the status of the specified component with other map data related to the component in the map database. As the comparison method, for example, it can be compared whether or not the status of the identified component corresponds to any one of the other map data associated with the component. The other map data can be, for example, a situation expected for the genre. Specifically, the comparison unit 23 compares whether or not the situation of the identified component corresponds to any of the situations expected for the genre associated with the genre of the component.
The writing unit 25 performs the writing based on the comparison result of the comparison unit 23. That is, as a result of the comparison, when the status of the identified component corresponds to any of the other map data associated with the component, the writing is performed, and when none of the map data is associated, Writing is cancelled.

  As a specific example of the device 21, description will be made below by taking as an example the case where the facilities are the “curse house Y”, the genre “haunted house”, the situation “scared” and “pounding” expected for the genre “haunted house” To do. In this example, when the status of the component is specified as “feeling good”, the writing to the map database is canceled. In other words, the situation “feeling good” of the identified component does not correspond to any of the situations “scary” and “pounding” expected for the genre “haunted house”. On the other hand, if the status of the specified component is “scary”, the status is written in the map database as map data of the facility “curse hall Y”.

FIG. 4 shows a map database creation device 31 according to another embodiment. 4, the same elements as those in FIGS. 1 and 3 are denoted by the same reference numerals, and the description thereof is partially omitted.
FIG. 4 shows a map database creation device capable of avoiding writing of the situation to the map database when it is determined that the situation of the identified component is not valid, as with the device 21 shown in FIG. 31. That is, the apparatus 31 further includes a genre information database 35 in the apparatus 21 illustrated in FIG. 3, and includes a comparison unit 33 instead of the comparison unit 23.
In the genre information database 35, a genre corresponding to the genre stored in the map database 5 and a situation expected for the genre are stored in association with each other. For example, as shown in FIG. 5B, a table in which “delicious”, “bright”, “fun”, and the like are associated with the genre “restaurant” is stored.
The comparison unit 33 refers to the map database 5, the identification unit 11, and the genre information database 35, and compares the status of the identified component with other map data related to the component in the map database. To do. As the comparison method, for example, it can be compared whether or not the status of the identified component corresponds to any one of the other map data associated with the component. The other map data can be the genre, for example. For example, when the constituent elements are the facility “curse house Y” and the genre “haunted house”, the comparison unit 33 refers to the genre information database 35 and is expected to be associated with the genre “haunted house”. Reads "Scared", "Sounding" etc. Then, the read “scary”, “pounding” or the like is compared with the situation specified by the specifying unit 11, for example, “pounding”, and the specified situation is included in the expected situation. Compare whether or not.

FIG. 6 shows a map database creation device 41 according to another embodiment. In FIG. 6, the same elements as those in FIGS. 1, 3, and 4 are denoted by the same reference numerals, and description thereof is partially omitted.
FIG. 6 shows a map database creation apparatus 41 that can create the map database in consideration of changes in biological information of wearable device users while existing in the components. That is, the device 41 further includes a filter unit 43 in the device 1 shown in FIG.
In this example, when extracting the information set related to the component from the receiving unit 7, the extraction unit 9 is an information set corresponding to the positional information of the component, and is a series that is temporally continuous. Extract information set. Further, the WD-derived information included in the information set is biometric information acquired by the wearable device.

The filter unit 43 refers to the extraction unit 9 and filters the extracted information set based on a change in the biological information of the information set while the wearable device user exists in the identified component. . In the series of information sets, when the difference between the biological information when it is determined that the vehicle has entered the facility and the biological information after a predetermined time has elapsed is equal to or greater than a predetermined threshold, the series of information sets This is done by sending to the specifying unit 11. On the other hand, when the difference is less than the predetermined threshold, that is, when the change in the biological information in the facility is small, the information set is excluded from the situation specifying target. As another example of the filtering, changes in biological information such as a change rate of biological information and a maintenance time after the change can be used.
In this example, the specifying unit 11 not only specifies the status of the component, but also performs a multi-step evaluation such as a five-step according to the value of the amount of change in the biological information, and the writing unit 13 It is good also as writing the said evaluation in the said map database as map data with the condition of a component. The same applies to the rate of change, the maintenance time after the change, and the like.

  As a specific example of the device 41, a case where the component is a facility “relaxation Z” and a genre “massage shop” will be described below as an example. Based on the location information of the facility “relaxation Z” stored in the map database 5, the extraction unit 9 extracts a series of information sets having location information corresponding to the location information. For example, the biological information included in the information set is a pulse rate. For example, when the maintenance time when the pulse rate is equal to or less than a predetermined value is equal to or greater than a predetermined threshold, the filter unit 43 sends the information set to the specifying unit 11 based on a series of temporal pulse rates. This is because the longer the maintenance time of the biological information, the more reliable the situation specified based on the biological information.
