Description

  The present invention relates to a sensing information sharing system, a sensing information sharing method, and a program for storing information obtained by sensing an event so as to be viewable.

  In recent years, sensor devices have become smaller and less expensive, and it has become possible to install a plurality of cameras in a living environment such as an office. Using them, it has become possible to acquire and preserve their own life records. It is also possible to utilize group activity records by sharing the information with the group.

  In order to use life records taken with a camera or the like later, it is necessary to store information on when, where, and what was taken according to the video. For example, Patent Document 1 describes a technique for automatically embedding subject information in a video image taken by a camera device.

  Also, when taking an image, care must be taken not to infringe the portrait rights of others. For example, the photographing system of Patent Document 2 acquires position information from an operation terminal possessed by an operator who is a subject, and calculates a photographing target region based on the position information of the camera unit, the pan / tilt angle, and the zoom magnification. Then, when it is determined that the operation terminal is located within the shooting target area, high-quality shooting is permitted, thereby enabling the operator to take a commemorative photo including the background image without infringing the portrait rights of others.

  In order to share life records with a group, it is convenient to distribute information through a communication network, but protection against leakage of personal information is necessary. Patent Document 3 describes a technology of an information distribution service system in consideration of confidentiality of personal information and security. The information distribution service system of Patent Document 3 compares the position information of the captured image data stored in the buffer unit with the latest position information of the vehicle-side system, and when the difference between the two position information is larger than a predetermined value. The captured image data is transferred from the buffer unit to the video file database.

  Patent Document 4 describes a technique for distributing materials only to participants in a conference even for a conference in which participants have not been determined in advance. When the material distribution system of Patent Document 4 detects a participant's mobile terminal in the conference hall, the server stores the ID of the participant's mobile terminal in the memory, and at the time of distributing the material, the participant mobile terminal ID is included in the conference material. Generate material information with a list attached and send it to the mobile terminal of the prospective participant. When the portable terminal receives the document information from the server, the portable terminal collates the terminal ID of the terminal itself with the terminal ID included in the document information. Save to memory.

  When sharing a personal life record in a group, there is a problem that one's own life record is viewed by another person and his secret information is stolen.

  For example, in the technique of Patent Document 2, no consideration is given to the range in which another person is reflected in the camera image and the operator can observe. For this reason, for example, when the activity of another person in the space divided by a partition near the operator is reflected in the camera, the operator can review the captured camera image later to view the image in the partition. The operation of the other person can be observed, and there is a possibility that the secret information of the other person in the vicinity of the operator can be seen by the operator himself.

  In addition, it is not a material that everyone must browse, such as the distribution of materials at the meeting of Patent Document 4, but only a part of the people know the recorded content of video footage that was filming a part of the conference room. The obtained information is not necessarily information that can be widely disclosed to people around.

  In related technology, there is a method in which a person who exists in a shooting area is specified from meeting attendance information or a relationship between a shooting area of a camera and a person's presence position, and browsing of information recorded and recorded is restricted. However, because he did not consider whether the person actually viewed the material used in the meeting, or whether he was able to know all the information in the captured video, By reviewing it, there is a risk that information that was originally unknown could be newly learned and the confidential information of others could be leaked.

  The present invention has been made in view of the above-described circumstances. When information acquired by a sensor is shared among a plurality of persons, a person who is browsing the information can observe the target of the information. The purpose is to disclose information only when there is.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration example of a sensing information sharing system according to Embodiment 1 of the present invention. The information sharing system 1 includes an event observation unit 11, an observation information storage unit 12, a position / direction detection unit 13, a position / direction information storage unit 14, an event occurrence information storage unit 15, a presence determination unit 16, a browsing range determination unit 17, and It is composed of a browseable person storage unit 18. Hereinafter, the sensing information sharing system 1 is simply referred to as the information sharing system 1.

  The event observation unit 11 is a sensor that acquires information in the installed environment, and there are a plurality of event observation units 11. Then, information obtained by observation is stored in the observation information storage unit 12. The event observation unit 11 includes, for example, a camera that captures an image or video and converts it into digital or analog image data.

  In the present invention, an event refers to any object that can be observed by a person and that can be viewed later on information that records the object. An event includes, for example, a conversation, a conference, a lecture, a demonstration, an experiment, or a phenomenon that a person can observe without using an instrument. The event also includes playing back a board written at a meeting or a lecture, or content including audio or images. Furthermore, it includes a conversation over a communication network, a meeting, a chat with characters, and collaborative creation of document data.

  The event observation unit 11 can use anything as long as it can record the above-described event in a form that can be browsed later. The event observation unit 11 includes, for example, a microphone, a camera, or a sensor that measures temperature, humidity, or weather data. The event observation unit 11 includes a board written at a meeting or a lecture, an agent that captures content reproduced at a meeting or a lecture, or a meeting or chat via a communication network, or document data created jointly. Also includes agents that capture and record.

  The event observation unit 11 stores data such as observed video images in the observation information storage unit 12 at regular intervals. At that time, the observed information storage unit 12 records the data such as the observed video images by assigning unique identification information to each of them.

  FIG. 2 shows an example of information for identifying the observed information. When the event observation unit 11 stores the observed information (hereinafter referred to as observation information) in the observation information storage unit 12, as shown in FIG. 2, the observation information number (information number) and the identification code of the event observation unit 11 ( (Observation means ID), the observation start date and time and the observation end date and time of the observed information are stored in association with each other. Information obtained by observing an event is stored in the observation information storage unit 12 and specified by an information number. The observation means ID is a code that identifies which observation means has observed the observation information of the information number. The event observation unit 11 sends the observed fact to the presence determination unit 16.

  For example, it is assumed that the event observation unit 11 whose observation means ID is S1 has shot an image on the east side of the room A during the period of 15:00 to 15:25 on August 1, 2009. In addition, it is assumed that the imaged area is a place that can be seen from other than the east side of room A. Then, it is assumed that the captured video is stored in the observation information storage unit 12 with the information number D1. For this information number D1, information of observation means ID = S1, observation start date / time = 2009/8/1 15:00, observation end date / time = 2009/8/1 15:25 is shown in the second line of FIG. ing. The event observation unit 11 with the observation means ID = S1 sends a signal to the presence determination unit 16 that observation has started at the point of time when observation of data to be newly recorded starts.

  The event occurrence information storage unit 15 holds information (event occurrence information) indicating how far the event observed by the event observation unit 11 can be observed spatially and temporally. If the event record is audio, it is within the range where the sound can be heard. Further, when the event record is an image, it is a range in which the event can be seen. When an event is displayed on the screen, it is a range where the screen can be visually recognized. The time when an event can be observed is the time when the event occurs. When an event is a conversation, a conference, a lecture, a demonstration, etc., it is the time when these events take place, but in reality it is the time to record the event. Further, when the event is content playback, it is the time when the content is played back.

  As the event occurrence information, a range of places where an expected event can be observed when the event observation unit 11 is installed is set. The time of the event occurrence information may be given as a schedule of the event observation unit 11, or a signal indicating that the event observation unit 11 is operating is output, and the start / end times are stored. Also good. When the event is content reproduction, a range in which the content to be reproduced can be observed is set in advance from the position of the device that reproduces the content. Then, the time of reproduction is stored as event occurrence information corresponding to the content. The time range of the event occurrence information may be stored along with the observation information. In that case, the event occurrence information may be only information on the range of the place where the event can be observed.

  The position / direction detection unit 13 detects information for identifying a person who is in a range where an event observed by the event observation unit 11 can be observed. For example, a position / direction information detecting device such as a GPS or an electronic compass is held at the position of the head or neck of the person, and the position of the held person and the direction in which the person is facing are measured. When a space in which an event can be observed is partitioned, such as a conference room or a lecture hall, the position of a person may be specified by detecting entry / exit with the ID card or the like. Furthermore, in order to detect the direction of the line of sight of the person, the direction of each person's head may be determined from an image taken in the hall. When the observation information of the event is not limited to the direction in which sound or temperature, humidity, etc. can be observed, there is no need to have information on the direction of the line of sight of the person present there.

  The position / direction detection unit 13 stores information for identifying the detected person in the position / direction information storage unit 14. FIG. 3 shows an example of position / direction information. For example, as shown in FIG. 3, the position / direction detection unit 13 associates the terminal ID, the person ID, the date / time, the position information, and the direction information, and stores them in the position / direction information storage unit 14. In the example of FIG. 3, the terminal identified by the terminal ID (which constitutes the position / direction detection unit 13) is held by the person identified by the person ID, and the terminal detects the position of the person and the orientation of the head. Assumes that

  Referring to FIG. 3, for example, a person with a person ID = n1 holding a terminal with terminal ID = T1 is on the east side of Room A at the date and time = 2009/8/1 15:00 and faces east. Is remembered. The date and time information may be the time when the position / direction information is received from the terminal. In addition, the terminal may detect a value of coordinates as position information, and may convert the value into a name or code for specifying a location from the coordinates in the information sharing system 1 that has received the value.

  When the event observation unit 11 acquires information, the presence determination unit 16 uses the information from the position / direction information storage unit 14 and the event occurrence information to identify persons who existed in the area where the target of the acquired information can actually be observed. The determination is made with reference to the information stored in the storage unit 15. From the information in the event occurrence information storage unit 15 and the direction information in the position / direction information storage unit 14 with respect to the person determined to exist by the presence determination unit 16, the browsing range determination unit 17 determines the event that the person is the target of observation information. It is determined whether it was actually observable. That is, it is determined from the position and direction of the person whether the person is facing the target event. The browsing range determination unit 17 stores the determined result in the browsing person storage unit 18 as browsing person information.

  FIG. 4 shows an example of event occurrence information. As shown in FIG. 4, the event occurrence information storage unit 15 includes information on the region observed by each event observation unit 11 and information on an observable region where a person can actually observe the observed event. Is remembered. For example, the observation means observation detailed area of the observation means ID number S1 in the event occurrence information storage unit 15 is “Room A East”, and the observable area is Room A.

  The presence determination unit 16 determines whether a person is present in the area that is displayed in the observable region of the event occurrence information storage unit 15 based on information from the position / direction information storage unit 14, and the event observation unit 11 The person who exists in the range which can observe the phenomenon which is observing is determined.

  FIG. 5 shows an example of observer information as a result of the presence determination. In the case of the information number D1, since the observation means ID is S1, the person who was present in the room A is determined using the position measurement system. Each time the existing person changes, the list is updated with time information. As shown in FIG. 5, when a person whose presence person ID is n1 has been in the room A for a period of 15:00 to 15:25 on August 1, 2009, all the determination results of n1 in FIG. Become.

  The presence determination unit 16 associates the result of determining the person existing in the range where the observation target event of the observation information can be observed with the information number and the observation means ID, and as shown in FIG. Create a table list with information. Then, the created table list is sent to the browsing range determination unit 17.

  FIG. 6 shows an example of browseable person information. Based on the table list of the presence determination results sent from the presence determination unit 16, the browsing range determination unit 17 and the direction information on the person in the position / direction information storage unit 14 and the event occurrence information storage unit 15 With reference to the information, it is determined whether or not a person who exists in the observable region can actually observe the event observed by the event observation unit 11. The browsing range determination unit 17 displays information of a person who is present in an area where the event observed by the event observation unit 11 can actually be observed and is directed toward the event as an information number as shown in FIG. And a table list divided by time zone in association with the observation means ID. The browsing range determination unit 17 can update the presence determination result information as illustrated in FIG. 5 to create the browseable person information illustrated in FIG. 6.

  For example, when the presence person ID = n1 is taken as an example, it can be seen from the table list (FIG. 5) created by the presence determination unit 16 that the person n1 is always present in the room A during the recording period of the information number D1. . However, there is a case where the content of the video moving to the information number D1 cannot be known because it is actually facing the west side of the room. Therefore, the browsing range determination unit 17 uses the information in the position / direction information storage unit 14 to determine whether the person n1 is actually facing the east side of the room A. Then, a list of determination results is created as a table list as shown in FIG. In the example of FIG. 6, since it was determined that the person n1 did not face the east side of the room between 15: 05-15: 10 on August 1, 2009, it is “x”. In this way, the browsing range determination unit 17 stores the determined result in the browsing person storage unit 18.

  In addition, when the observation information of an event does not limit the direction in which sound, air temperature, humidity, etc. can be observed, the viewing range determination unit 17 may be omitted. In that case, the determination result of the presence determination unit 16 is stored in the browsable person storage unit 18 as browsable person information.

  When a request to disclose the observation information in the observation information storage unit 12 is received using the browsable person information, the disclosure availability of the observation information is compared with the person who has requested the disclosure and the browsable person information. It is possible to determine whether information disclosure is possible. In the case of the browseable person information shown in FIG. 6, if there is no person who can observe the event other than the existence person in FIG. 6, the person other than n1 to n10 is requested to browse the observation information with the information number 1. If it is, it can be determined that it cannot be disclosed. Moreover, when the viewer information is included as an observer in a short time, it can be determined that the observation information can be disclosed.

  When the viewable person information corresponding to the requested observation information includes the ID of the requested person, whether or not the observation information can be disclosed is determined by the ratio of the person's observable time to the observation time. It is also possible to do. For example, in the case of the browseable person information shown in FIG. 6, the presence person ID = n10 is not observable only during 15: 00-15: 02, but is observable for the remaining time. May be disclosed. In addition, the presence person ID = n7 can be observed only between 15: 02-15: 05, and cannot be observed at other times, so it may be determined that the observation information cannot be disclosed.

  FIG. 7 is a flowchart illustrating an example of an operation for generating browsable person information according to the first embodiment. FIG. 7 shows a case where one event is observed. When the event observation unit 11 observes the event and starts acquiring observation information (step S11), the position / direction detection unit 13 detects a person in the observable region and stores it in the position / direction information storage unit 14 ( Step S12). Until the observation is finished (step S13; NO), the person detection in the observable area is continued (step S12).

  When it is time to end the observation (step S13; YES), the acquisition of the observation information is ended (step S14), and the observation information is stored in the observation information storage unit 12. The presence determination unit 16 determines a person in the observable area based on the information in the position / direction information storage unit 14 and the event occurrence information, and sends the result to the viewing range determination unit 17 (step S15). The browsing range determination unit 17 refers to the direction information that the person is facing in the position / direction information storage unit 14 and the information in the event occurrence information storage unit 15, so that the person present in the observable region is the event observation unit 11. It is determined whether or not the observed event is actually observable (step S16). Then, the generated browseable person information is stored in the browseable person information storage unit 18 (step S17), and the process ends.

  In the present embodiment, as described above, the person who wants to browse the information acquired by the event observation unit 11 exists at the site where the event observation unit 11 has acquired information, and directly observes the event. Is determined from the position information of the person acquired in advance and stored. Therefore, when the event observation unit 11 acquires information on a specific event and shares the information among a plurality of persons, only for a person who can observe the event when the event occurs, It becomes possible to disclose information.

  Furthermore, the information of the direction in which the person who was in the range where the event was observable was stored, and whether the event was observable including the direction of the person was determined so that the person who requested the viewing was watching. It is possible not to disclose the observation information of the missing event to the person.

(Embodiment 2)
FIG. 8 is a block diagram showing a configuration example of a sensing information sharing system according to Embodiment 2 of the present invention. In the second embodiment, when the identification information (ID) of a person who has requested browsing of observation information is included in the viewer information of the observation information, the observation information is disclosed to the person who has requested browsing.

  The information sharing system 1 according to the second embodiment includes a browsing request input unit 19, an information disclosure determination unit 20, and an information presentation unit 21 in addition to the configuration of the first embodiment. Other configurations are the same as those in the first embodiment, and the processes until the observation information and the viewer-accessible information are stored are the same as those in the first embodiment.

  A device that is actually operated in the browsing request input unit 19 and a device that displays information in the information presentation unit 21 may be configured by a terminal near the person who requests browsing. In that case, the main body including the observation information storage unit 12 and the browsable person storage unit 18 of the information sharing system 1 is configured by a server connected to a communication network (not shown). Then, a browsing request is input from the terminal via the communication network, and the observation information is displayed on the terminal via the communication network.

  The browsing request input unit 19 receives a browsing request from a person who wishes to browse observation information. The browsing request includes identification information of a person who requests browsing and information for specifying observation information for which browsing is requested. The identification information of the person who requests browsing may be input by logging into the information sharing system 1. The information specifying the observation information may be inputted by displaying a list of information for identifying the observation information as shown in FIG. 2 and selecting from the list.

  When there is a request to view observation information, the information disclosure determination unit 20 refers to the viewable person information corresponding to the observation information requested to be browsed, and the ID of the person who requested the observation information to be viewed and the requested observation information. Compare browseable person information corresponding to. Then, if the ID of the person who requested browsing is included in the browseable person information, it is determined that the observation information requested to be browsed can be disclosed.

  The information presenting unit 21 presents the observation information determined to be disclosed by the information disclosure determining unit 20 to the person who has requested browsing. The observation information is presented by displaying it on a device adapted to the media. For example, an image is presented by being displayed on a display device. If the observation information is voice, it is presented by playing it through a speaker.

  In the case of the browseable person information shown in FIG. 6, if there is no person who can observe the event other than the existence person in FIG. 6, the person other than n1 to n10 is requested to browse the observation information with the information number 1. If it does, it will be judged that it cannot be disclosed. When the viewer information is included as an observer in a short time, it can be determined that the observation information can be disclosed.

  When the viewable person information corresponding to the requested observation information includes the ID of the requested person, whether or not the observation information can be disclosed is determined by the ratio of the person's observable time to the observation time. May be. For example, in the case of the browseable person information shown in FIG. 6, the presence person ID = n10 is not observable only during 15: 00-15: 02, but is observable for the remaining time. May be disclosed. In addition, the presence person ID = n7 can be observed only between 15: 02-15: 05, and cannot be observed at other times, so it may be determined that the observation information cannot be disclosed.

  FIG. 9 is a flowchart illustrating an example of an information disclosure operation according to the second embodiment. The browsing request input unit 19 receives a browsing request for observation information (step S21, step S22; NO). When a browsing request is input (step S22; YES), the browsing request input unit 19 acquires the identification information of the person ID and observation information requested for browsing (step S23).

  The information disclosure determination unit 20 refers to the browseable person information of the observation information requested to be browsed (step S24), and checks whether or not the person ID requested to be browsed is included in the browsable person information (step S25). If the person ID requested to be browsed is included in the browsable person information (step S25; YES), it is determined that the observation information requested to be browsed can be disclosed, and the observation information is presented via the information presentation unit 21 (step S25). S26). As described above, whether or not the observation information can be disclosed may be determined by the ratio of the observable time of the person to the observation time.

  When the person ID requested to be browsed is not included in the browseable person information (step S25; NO), it is determined that the observation information requested to be browsed cannot be disclosed, and “observation information cannot be disclosed” is presented (step S27). . In both cases where the observation information is presented and not presented, the process returns to a new browsing request input and the process is repeated.

  As described above, according to the information sharing system 1 of the second embodiment, whether or not the ID of the person who has received the browsing request for the observation information and requested to browse is included in the browsable person information of the observation information. Only when the information sharing system 1 determines and is included in the browsable person information, the observation information is disclosed to the person who requested the browsing.

(Embodiment 3)
FIG. 10 is a block diagram showing a configuration example of a sensing information sharing system according to Embodiment 3 of the present invention. In the third embodiment, when the identification information (ID) of the person who requested viewing of the observation information is included in the viewable person information of the observation information, only the observation information of the portion of the time when the person was observable Is disclosed to the person who requested to view the observation information.

  The information sharing system 1 according to the third embodiment includes a disclosure range editing unit 22 in addition to the configuration of the second embodiment. Other configurations are the same as those of the second embodiment. The process until the observation information and the browseable person information are stored is the same as that in the first embodiment. Further, the process until receiving the browsing request and determining whether or not the observation information can be disclosed is the same as in the second embodiment.

  When the disclosure disclosure editing unit 22 determines that the observation information can be disclosed by the information disclosure determination unit 20, only the portion of the observation information requested to be browsed by which the person who requested browsing can observe the target event. To edit. For example, in the case of the browseable person information shown in FIG. 6, when browsing of the observation information with the information number 1 is requested by a person whose existing person ID is n1 to n10, Then, edit the observation information only in the part marked with “○”.

  When the observation information is a combination of audio and video, the result of presence determination in FIG. 5 is “◯”, but in the viewable person information in FIG. 6, the portion of “×” (for example, 15 of the presence person ID = n1). : 05-15: 10), the person was in an observable area at that time, but was not facing the event, so only the video of that part may be deleted and the audio may be left. . That is, in the reproduction of the portion, only the sound may be reproduced while the immediately preceding image is displayed.

  The information presentation unit 21 presents the observation information edited by the disclosure range editing unit 22 to the person who has requested browsing. The presentation of the observation information is performed by displaying on the device adapted to the media, as in the second embodiment.

  FIG. 11 is a flowchart showing an example of the operation of information editing disclosure according to the third embodiment. Steps S31 to S35 and S38 in FIG. 11 are the same as steps S21 to S25 and S27 in FIG.

  The information disclosure determination unit 20 checks whether or not the person ID requested to be browsed is included in the browsable person information (step S35). When the person ID requested to be browsed is included in the viewable person information (step S35; YES), the disclosure range editing unit 22 can observe the target event of the person requested to browse among the observation information requested to be browsed. Editing is performed only on the part (step S36). Then, the information presentation unit 21 presents the observation information edited by the disclosure range editing unit 22 (step S37).

  When the person ID requested to be browsed is not included in the browseable person information (step S35; NO), it is determined that the observation information requested to be browsed cannot be disclosed, and “observation information cannot be disclosed” is presented (step S38). . In both cases where the observation information is presented and not presented, the process returns to a new browsing request input and the process is repeated.
