Abstract

A system for announcing a user of the fact that the user has left behind a thing because of interruption or a change of situation. An interruption is detected from environment information representing the position or state of a thing or interruption information. The name of the thing that the user had immediately before the detection of an interruption is determined and recorded in a left-behind thing candidate list. Referring to action information on the position and posture of the user, response of the user to the interruption or reversion of the user from the handling of the interruption is detected, and the name of the thing that the user had during the time from the response till the reversion and before the response is deleted from the left-behind thing candidate list. After the reversion of the user from the handling of the interruption, the user is announced about the thing of which the name is recorded in the left-behind thing candidate list as a left-behind thing.

Description

Description Lost and found service system, processing method and program

The present invention relates to a lost item service system that notifies a user of a lost item when the user forgets the item due to an interruption or a change in circumstances that occur around him, and a process executed by the lost item service system. The present invention relates to a method and a program for causing a computer to execute the processing method. Background art

At present, a system has been proposed that executes various services that support a user's life using an environment realized by ubiquitous network technology. In a ubiquitous environment, the network functions as a so-called “Kuroko”, and it is possible to provide a variety of services by combining the functions of home appliances (appliances) that have communication functions and are connected to the network.

When considering services that support a user's life, there is a “forgettable” problem that occurs daily in the user's home. Forgotten items are things that should be brought in but are forgotten, or those items that have been forgotten. There are two main situations in which lost items occur, as follows.

As the first situation, for example, consider a situation in which a handkerchief is forgotten. In the morning, when the user is preparing to go to work, talking to family members interrupts the preparation and forgets the handkerchief they should have.

As the second situation, for example, consider a situation in which a “entrance certificate card (entrance pass)” is forgotten. Suppose you had an entry pass on the table the night before to make it easier to find. Looking at the clock while preparing for work in the morning, I noticed that it was almost time to be late, so I left the house in a hurry and interrupted my preparations from that point on, so I had to pass the entrance pass, which was what I needed to have. Forget it.

As in the first situation, there was an “unexpected interruption” to the user, It is thought that the situation change around the user, as in the second situation, could cause lost items. (Reference: Noriko Aragaki et al., "Why do people lose things? Examination of Human Cognitive Process in the Environment ”, Human Interface Symposium (HIS) 2003, Human Interface Society.

It would be very useful for users if they could provide such a life support service that notifies them of leftovers that occur daily in the home.

Thus, the present invention provides a lost item service that determines and notifies what is left behind in order to remind the user of an unexpected interruption around the user or a lost item caused by a change in situation. It aims to provide a system and a processing method program. Disclosure of the invention

In order to achieve the above object, a first invention is a lost item service system for notifying a user of a lost item caused by interruption. 1) Environmental information indicating the position and state of an object; A distributed database that stores motion information indicating the position and orientation and interaction information indicating the interaction between the user and the human or the user and the object; 2) an interface that detects an interruption from the environmental information or the interaction information 3) Based on the interaction information, acquire an object that has caused an interaction with the user in a situation immediately before the detection of the interaction, and A user status storage means for recording; and 4) an interrupt of the user using the operation information. In response to the interruption or the return from the interruption, the interruption corresponding to the situation from the response to the return and deleting the thing existing within the predetermined range of the user from the forgotten thing candidate list. · Return detection means, and 5) in the situation after the return, a lost article notification means for notifying an item recorded in the lost article candidate list as a lost article.

The system according to the first invention includes environmental information indicating the position and state of the user's object, operation information indicating the position and posture of the user, and interaction between the user and the human or the user and the object. A distributed database for storing interaction information indicating an operation is provided. Environment information, operation information, and interaction information of the distributed database are obtained from sensor information of sensor appliances connected to a ubiquitous network installed in the home. Objects are things that users can carry or use.

Then, the interruption detecting means detects the interruption from the environment information or the interaction information of the distributed database. An interruption is an interruption caused by a change in an object or environment occurring around a user, or by a human. Then, based on the interaction information, the user situation storage means obtains, based on the interaction information, the object that has interacted with the user in the state immediately before the detection of the interruption, that is, the thing that the user has or uses, and obtains the information. Record the object in the list of lost objects.

In addition, the interruption detecting / return detecting means detects the user's response to the interruption or the return from the interruption by using the operation information of the distributed database. Then, in the situation from the response of the interruption to the return, the item that has interacted with the user, that is, the item possessed or used by the user is deleted from the lost item catching list. Then, in the situation after returning from the interruption, the item recorded in the lost item candidate list is notified as the lost item by the lost item notification means.

In this way, for example, by responding to an interruption such as talking to someone, the user can be made aware of a lost item that has been forgotten when returning to the original situation. .

Further, the second invention is a lost object service system for notifying a user of a lost object caused by a change in a situation, and 1) operation information indicating a position and a posture of the user and information of a user, an object, or an environment. A distributed database that stores unique information indicating attributes and interaction information indicating the interaction between the user and the object; and2) detecting a change in the user's situation from the operation information described above, and based on the unique information. A situation change detecting means for determining whether or not the changed situation is a habitual situation; and 3) when the changed situation is a habitual situation, from the interaction information, A possession comparison means for acquiring the necessary items that the user should normally possess and the items currently possessed by the user, and comparing the required items with the currently possessed items; 4) And a forgotten thing notification means for notifying the necessary thing, which is not currently possessed, as a forgotten thing as a result of the comparison.

As described above, the system of the second invention includes, as described above, motion information indicating the position and orientation of the user, unique information indicating the attributes of the user, the thing, or the environment, and interaction information indicating the interaction between the user and the thing. And a distributed database for accumulating the information. Proprietary information is information about the attributes of a user, object, or environment, such as the nature, behavior, and habits.

The situation change detection means detects a change in the situation of the user from the operation information of the distributed database. Furthermore, based on the unique information, it is determined whether the changed situation is a habitual situation.

For example, if the situation changes from “having breakfast” to “being at the front door”, the user's habits recorded as unique information “Weekday to work at home around 8 am The change is judged to be a habitual situation (commuting).

Then, based on the interaction information of the distributed database, the belongings comparison means and the things that the user needs in a habitual situation, that is, the things that the user should have when going to work, and the things that the user currently has, that is, the things that the user currently has And compare the necessary items with the items currently possessed.

As a result of the comparison, a lost item is identified by a lost item notifying device, and the lost item is notified as a lost item.

This allows the user to have a forgotten thing that he or she should have when the changed situation is a habit, such as going to the door to leave the house after having breakfast. The user can be made aware of it.

Further, the third invention is a lost item service system for notifying a user of a lost item caused by a change in a situation, and 1) indicating operation information indicating a position and a posture of the user and attributes of the user, object, or environment. Distributed data that stores unique information that stores unique information and interaction information that indicates the interaction between a user and an object 2) a situation change detecting means for detecting a change in the situation of the user from the operation information; and 3) an object held by the user in the situation immediately before the changed situation from the interaction information. A property comparison means for acquiring the property possessed by the user in the current situation, and comparing the property possessed with the property currently possessed, 4) a result of the comparison, And a forgotten item notifying unit for notifying the owned item and the item not currently owned as a lost item.

As described above, the system according to the third aspect includes, as described above, motion information indicating the position and orientation of the user, unique information storing unique information indicating attributes of the user, the thing, or the environment, and an interaction between the user and the thing. And a distributed database that stores interaction information indicating

Then, the status change detecting means detects a change in the user's status from the operation information of the distributed database. Here, it is assumed that the change in the situation is a change from “going out of the entrance” to “coming home and being at the entrance”.

Then, based on the interaction information in the distributed database, the possession comparing means uses the interaction information of the distributed database to identify the object (eg, bag, umbrella) owned by the user in the situation immediately before the change and the object owned by the user in the current situation (eg, For example, a bag) is acquired, and the items possessed are compared with the items currently possessed. Then, as a result of the comparison, a lost item (umbrella) that is possessed but not currently possessed is notified by the lost item notification means.

As a result, the user can be made aware of, for example, a lost item that the user had in the previous situation but not currently, for example, a lost item on the go. Brief Description of Drawings

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the best mode for carrying out the present invention will be described.

The lost item service system 1 is a data processing system that executes a service of analyzing a lost item caused by an interruption and notifying a user based on predetermined information obtained by accessing the distributed database 2.

The distributed database 2 is a distributed database system that accumulates various information generated from sensor information of a sensor appliance connected to a ubiquitous network installed in a user's living space. The sensor information is data acquired by the sensor appliance, such as image data, audio data, pressure transition data, and ID tag data.

The distributed database 2 includes an environment information database 21, an operation information database 22, and an interaction database 23.

The environment information database 21 stores environment information indicating the location and state of an object. Environmental information is information about the environment, such as loud noises, changes in objects such as lighting, lighting of toasts, and environmental changes. Here, it is assumed that the object is an article that can be carried around by the user and an object to be used. An object has a meaning that includes not only the physical existence of an object, but also the state of the object.

The environmental information (position, state) of an object is provided with an ID tag that stores identification information for non-contact radio wave identification, such as an RFID (Radio Frequency Identification) tag, and an RFID tracker (sensor appliance). Measured by It is generated based on the obtained sensor information. Note that it may be generated based on sensor information from a plurality of cameras (sensor appliances).

The motion information database 22 stores motion information indicating the position and posture of the user. The motion information is information on the motion of the human, such as the position and posture of the human including the user. The operation information may be generated based on sensor information from a plurality of cameras (sensor appliances).

The interaction database 23 stores interaction information indicating an interaction between a user and a human or between a user and an object. Interaction refers to the interaction between humans and humans or between humans and objects. Interaction information is information about interactions, such as the effect that a human talks to a human (user) and the effect that a human (user) has an object. The interaction is specified by, for example, the positional relationship between the human and the object, the usage status, and the like.

The lost item service system 1 includes an interruption detection unit 11, a user status storage unit 12, interruption correspondence / recovery detection unit 13, a lost item candidate list 14, a lost item notification unit 15, and an evaluation writing unit 16. , And a service history database 17.

The interruption detecting unit 11 is processing means for detecting an interruption occurring around the user from the environment information of the environment information database 21 or the interaction information of the interaction database 23.

Interruptions are changes in the environment or things that occur around the user, interruptions of people, and so on. For example, a change in the environment such as “loud sound”, a change in an object such as “toast burned”, or an interaction such as “a human talks”.

When an interruption is detected by the interruption detecting unit 11, the user situation storage unit 12 communicates with the user in a state immediately before the detected interruption based on the interaction information of the interaction database 23. This is a processing means for acquiring a thing in which an interaction has occurred within a predetermined range, and recording the acquired thing in a lost item candidate list 14. Here, "within the predetermined range" means that This is the case where a certain distance is within a certain range, the interaction between a human and an object is calculated as energy, and the energy is more than a certain value.

That is, in the situation immediately before the occurrence of the interruption, the user status storage unit 12 stores the user identification information (user ID) and the identification information (thing ID) of the thing the user had or used. Is recorded in the lost item candidate list 14 together with the time stamp. This is because the thing that the user has immediately before the occurrence of the interruption is likely to be forgotten.

The return detection unit 13 detects the response to the user's interruption or the return from the interruption by referring to the operation information database 22. In the situation from the response to the interruption, the return detection unit 13 This is a processing means to delete items existing within the range of from the lost and found list 14. Specifically, the interruption detection / return detection unit 13 uses the operation information of the operation information database 22 to detect the interruption of the user when the interruption detection unit 11 detects the interruption. If the user responds to the interruption or returns from the interruption and determines that the user has responded to the interruption and has returned from the interruption and has returned to the state before the interruption, the interaction database 23 is interpreted. This is a processing means for referring to the user's current possession and deleting from the forgotten property list 14 the possession currently owned by the user and possessed before the response.

If the user does not respond to the interruption, there is no change in the user's situation, so it is unlikely that the user forgets. Conversely, when the user responds to the interruption, the operation being performed by the user is interrupted or the environment changes, so that it is easy for the user to forget something. In addition, a thing that is interacting with the user corresponding to the interruption and is a lost object candidate means that the user keeps or uses the thing even after the response. Such a thing will not be forgotten.

The lost item capture list 14 is storage means for storing, for each user, the identification information or the name of a thing that is a lost item candidate. The lost item notification unit 15 is a processing means for taking out an item recorded in the lost item candidate list 14 and notifying it as a lost item when the user detects that the user has returned from the interruption correspondence / return detection unit 13. is there.

At the time of notification, the lost item notification unit 15 may refer to the information in the distributed database 2 and notify the name of the lost item and the place where the item is located.

In addition, the forgotten item notification unit 15 retrieves, from the forgotten item list 14, items that had a high degree of interaction with the user in the situation immediately before the detection of the interruption, that is, items that were worn by the user. Notify as.

Also, the lost item notification unit 15 may be configured to notify a lost item only when an inquiry about the lost item is received from the user. This is because when there is an inquiry from the user, it is a case where the user has recognized that the user has left something behind, and the probability of the occurrence of the lost item is high.

Further, the lost item notification unit 15 may refer to the environmental information database 21 and notify the lost item and the location of the lost item. This is because it is convenient for the user to know where the lost item is.

In addition, when notifying a user of a lost item, the lost item notification unit 15 may refer to the evaluation of the service history database 17 and specify an item to be lost. The purpose is to improve the accuracy of notifications by referring to the evaluation of previous notifications, because there are situations in which each user is likely to forget or lose something. The evaluation writing unit 16 is a processing unit that writes the user's evaluation of the notification of the lost item in the service history database 17.

The evaluation writing unit 16 evaluates that the lost item notification unit 15 has determined that the notification was correct (successful) when the user obtained the thing that was notified as the lost item, and when the user did not obtain it. If it is determined that the notification was incorrect (failed), the evaluation is written to the service history database 17.

Also, the evaluation writing unit 16 evaluates the notification as a success when the lost item notification unit 15 receives a response that acknowledges the lost item from the user, and transmits the notification when the lost item notification unit 15 receives a response that does not recognize the lost item. If a failure is assessed, one of the assessments will be serviced. Write to the history database.

FIG. 2 is a diagram showing a processing flow of the lost item service system 1.

The interruption detecting unit 11 of the lost item service system 1 waits for the detection of the interruption, and detects the interruption based on the information of the environment information database 21 or the interaction database 23 (step S10). ). The user situation storage unit 12 refers to the belongings of the situation immediately before the user specified by the interaction information between the user and the object in the interaction database 23, obtains the thing to be forgotten, and obtains the user name (ID ), The object is recorded in the lost item candidate list 14 together with the time stamp (step S11).

The return detection unit 13 determines whether or not the user has responded to the interruption detected in the processing of step S10 based on the operation information of the operation information database 22 (step S1). 2). If it is determined that the user did not respond, of the items recorded in the lost item candidate list 14, the items that the user had before correspondence were deleted from the lost item candidate list 14 (step S 13). If it is determined that the user has responded to the interruption, the interruption detecting 'return detection unit 13 determines whether the user has returned from the interruption and has returned to the same state (step S14). If it is determined that the user has returned from the interruption and has returned to the same state, the process returns to step S10. On the other hand, if it is determined that the user has returned from the intervention and has not returned to the same state, the lost item notification unit 15 determines whether there is an inquiry about the lost item from the user (step S15). If there is an inquiry from the user about the lost item, the item recorded in the lost item trap list 14 is notified as a lost item (step S16). If there is no inquiry about the lost item from the user, the process returns to step S10.

After that, the evaluation writing unit 16 evaluates that the service is “successful” when the user picks up the notified object, and evaluates that the service is “failed” when the user does not pick up the notified object. These evaluations are recorded in the service history database 17 (step S17), and the process returns to step S10. Note that the lost item notification unit 15 may notify the lost item in the process in step S16 without performing the determination process in step S15.

Hereinafter, a specific example will be described.

It is assumed that user U 1 is drinking coffee in the living room before going to work. It is assumed that the user has already finished dressing up, for example, wearing a watch, but the entrance pass has been placed on a nearby table to be put in his pocket.

In this situation, environmental information indicating the position and state of each of the coffee cup, clock, and entrance pass is recorded in the environmental information database 21. In addition, motion information indicating the position and orientation of the user U 1 is recorded in the motion information database 22. Also, there is an interaction between user U1 and the coffee cup, clock, and entrance pass. This interaction information is not recorded in the interaction database 23.

Here, let's say that a loud noise can be heard from the children's room. In the distributed database 2, this event is added to the environment information database 21. Therefore, the interruption detecting unit 11 detects an interruption (change in environment), and the user status storage unit 12 stores the interaction information. Record “Coffee cup, clock, admission pass” in the lost item list 14.

However, if the user U 1 does not respond to this interruption, there is no change in the operation information of the user U 1. Therefore, the interruption correspondence / return detection unit 13 indicates that the user U 1 did not correspond to the interruption. As an example, “Coffee cup, clock, admission pass” is deleted from the lost item candidate list 14.

Suppose that after a while, the child's room is heard by user U2 calling user U1. In the distributed database 2, the environment information is added by this event, and the interruption detecting unit 11 detects the interruption (occurrence of the interaction). The user situation storage unit 12 records “coffee cup, clock, entrance pass” in the lost item candidate list 14 in the same manner as described above.

User U1 responds to this call with his coffee cup and admission pass to the children's room and talks to user U2. Since the operation information and interaction information of the user U1 change, the interruption correspondence It detects that the user U1 has responded to the interruption based on the operation information. In addition, the information “coffee cup, clock, admission pass” owned by the user U 1 in this situation is detected from the interaction information.

Thereafter, it is assumed that the user U1 leaves the child room and returns to the living room with the coffee cup and the entrance pass in the child room. Since the operation information of the user U1 changes, the interruption correspondence / return detection unit 13 detects that the user U1 has returned from the interruption and returned to the same state based on the operation information database 22. To detect. In addition, by referring to the operation information database ^{2 2} and interaction databases 2 3, those around the user U 1 (those possessed) Get the "clock", is forgotten object candidate list 1 4 " Coffee cup, clock, admission pass. " Then, the object “clock” which the user U 1 currently has and has before the correspondence to the intervention is deleted from the lost item candidate list 14.

When the lost item notification unit 15 receives a question from the user U1 such as "Is it forgotten?", It looks at the items recorded in the lost item candidate list 14 and finds, for example, "Coffee power and entrance pass. Is converted to audio data and notified to user U1.

Here, it is assumed that the user U1 returns to the child's room and picks up only the entrance pass. The evaluation writing unit 16 evaluates the notification of “coffee cup” as failure and the notification of “entrance pass” as success, and records this evaluation in the service history database 17. In this way, the lost item notification unit 15 refers to the evaluation of the service history database 17 when identifying a lost item in the same situation, and a “coffee cup” is included in the lost item trap list 14. Make sure that coffee cups are not forgotten even if they are recorded.

FIG. 3 is a diagram showing a configuration example of a lost item service system according to the second and third inventions.

The lost item service system 3 is a data processing system that executes a service of analyzing a lost item caused by a change in a situation and notifying a user based on predetermined information obtained by accessing the distributed database 2.

Distributed database 2 is similar to distributed database 2 shown in FIG. It consists of an information database 22, an interaction database 23, and a unique information database 24. The environmental information database 21 and the interaction database 23 are the same as the databases shown in FIG.

The unique information database 24 accumulates unique information relating to attributes such as characteristics of humans, objects, and environments, behavioral tendencies, and habits.

The lost item service system 3 includes a situation change detection unit 31, a belongings comparison unit 32, a lost item notification unit 33, an evaluation writing unit 16, and a service history database 17.

The situation change detection unit 31 detects a change in the situation of the user from the operation information in the operation information database 22, and based on the unique information in the unique information database 24, the changed situation is a habitual situation. It is a processing means for determining whether or not.

The possession comparison unit 32 acquires the necessary items that the user should normally possess in the habitual situation and the items currently possessed from the interaction information in the interaction database 23, and obtains the necessary items and the current items. This is a processing means to compare with the possessed item.

The forgotten item notification unit 33 is a processing means for notifying the user of an item that is necessary and not currently possessed as a lost item.

For example, if a user changes from a living room to a front door to go to work, information about the user's habits recorded as unique information ("Leave a house around 8:00 am on weekdays") And so on), it is determined that this situation change is a habitual situation that occurs repeatedly, and in this situation, the things that the user should normally have are acquired as the necessary things and the things that the user should have By notifying the user of items that he does not have at the moment, the user can be made aware of what is left behind.

In addition, the possession comparison unit 32, based on the interaction information in the interaction database 23, identifies the object possessed by the user in the situation immediately before the changed situation and the article possessed by the user in the current situation. Acquire each one and compare the items you had in the last situation with the items you currently have. Then, the forgotten item notification unit 33 forgets the items that the user has but does not currently have. Notify you

For example, when a situation change occurs, such as when the user returns home and enters the entrance, the user has possession in the situation immediately before (the morning, he is at the entrance to work), but the current situation By identifying and notifying the items that the user does not have (at home and at the entrance), the user can be made aware of, for example, lost items outside.

Note that the evaluation writing unit 16 and the service history database 17 in FIG. 3 are the same processing units as the processing units with the same numbers shown in FIG.

FIG. 4 and FIG. 5 are diagrams showing the processing flow of the lost item service system 3.

The situation change detector 31 of the lost item service system 3 detects a change in the situation of the user from the operation information of the operation information database 22 (step S20). Further, based on the unique information, it is determined whether or not the changed situation is a habitual situation (step S21). If the changed situation is a habitual situation, the process proceeds to step S22. If the changed situation is not a habitual situation, the process proceeds to step S31 in FIG.

The possession comparison unit 32 refers to the unique information database 24 and the interaction database 23, and when the changed situation is a habitual situation, the user usually possesses the object that was normally possessed in the habitual situation. Is acquired as a necessary object (step S22), the object possessed by the user in the current situation is acquired (step S23), and the necessary object is compared with the object currently possessed. (Step S2 4). Then, the lost item notification unit 33 notifies the user of items that are necessary and are not currently possessed as lost items (step S25).

After that, the evaluation writing unit 16 evaluates that the service is “successful” when the user picks up the notified object, and evaluates that the service is “failed” when the user does not pick up the notified object. These evaluations are recorded in the service history database 17 (step S26), and the process returns to step S20.

In the process in step S21, if the changed situation is not a habitual situation, the possession comparing unit 32 reads the last situation from the interaction database 23. Then, the object owned by the user and the object owned by the user in the current situation are acquired (step S31), and the object possessed in the immediately previous situation is compared with the object currently possessed. (Step S32). Then, the lost item notification unit 33 notifies an object which was possessed in the previous situation but is not currently possessed as a lost item outside (step S33).

Thereafter, the evaluation writing unit 16 evaluates that the service has been “successful” when the user has acknowledged the forgotten item, and has determined that the service has “failed” when the user has rejected the forgotten item. The evaluation is recorded in the service history database 17 (step S34), and the process returns to step S20.

Hereinafter, a specific example will be described.

It is assumed that the user U1 has gone from the living room to the entrance to work. The situation change detection unit 31 detects this situation change from the operation information. In addition, based on information about the user's habits recorded as unique information (such as "leaving home around 8 am on weekdays"), it is determined whether the detected changed situation is a habitual situation of the user. I do.

The possession comparison unit 32 acquires, from the interaction information, what the user had in the same situation, for example, “bag, car key, entrance pass, etc.” as necessary belongings. Then, by acquiring the “bag, car key” as the current item, and comparing them, it can be seen that the item that was always possessed but not currently possessed is the “entrance pass”. Therefore, the lost item notification unit 33 notifies the user U1 of the lost item by voice data such as "I forgot the entrance path."

It is assumed that user U 1 has returned home and entered the entrance. The situation change detection unit 31 detects this change in the situation from the operation information.

The possession comparison unit 32 acquires, for example, “bag, car key, entrance pass, umbrella, etc.” from the interaction information as the last situation, that is, what the user had when he went out in the morning. Then, they obtain “bags, car keys, entrance passes, etc.” as the items they currently have, and compare them to find that the items they had when they went out, but they do not have now are “umbrellas”. You can see that there is. Therefore The lost item notification unit 33 notifies the user U1 of the lost item outside by voice data such as "I forgot the umbrella."

Although the system according to the present invention has been described above, the present invention can also be realized as a program for causing a computer to execute the processing method executed by the system described as the embodiment.

The program according to the present invention can be stored in a computer-readable recording medium, provided by being recorded on such a recording medium, or provided by transmission / reception using various communication networks via a communication interface. Is done. Industrial applicability

INDUSTRIAL APPLICABILITY As described above, the present invention is suitable for a system that provides various services that support a user's life using a ubiquitous network environment.
