  ADVANTAGE OF THE INVENTION According to this invention, the organization activity recording device and organization activity recording method which can implement | achieve the optimal working space for implementing a joint work using various apparatuses, implement | achieving flexibility, openness, and non-concentration And can provide programs.

  Hereinafter, the best mode for carrying out the present invention will be described. FIG. 1 is a diagram for explaining the outline of the organizational activity recording apparatus according to the present embodiment. In FIG. 1, PW is a personal workspace peer, SW is a shared workspace, AP is an access point peer, and α and β are workspaces. The personal workspace peer PW provides the user with a workspace. The access point peer AP connects the work space α and the work space β.

  The organizational activity recording apparatus forms a collaborative work space by integrating work spaces PW recognized to exist in the same time zone and in the same work space. For this reason, the shared workspace SW can be formed ad hoc among a plurality of personal workspace peers PW. Thereby, when working in a certain work space, it is possible to link calculation resources such as documents and application components that can be used in the work space. For example, in a situation where multiple workers are collaborating by moving through various workspaces in the office, the optimum environment for collaborative work using the various computational resources is automatically automated. A system architecture for a ubiquitous computing environment can be provided to assist in set-up.

  FIG. 2 is a diagram for explaining a hybrid peer-to-peer network. The communication network used in the work space of the organizational activity recording apparatus of the present invention is a peer-to-peer (P2P) network. There are two types of P2P networks: “Pure P2P network” and “Hybrid P2P network”.

  A pure P2P network is a configuration in which control messages and contents are directly transmitted and received between peer devices A to E as each component of the network system without going through an index server. The peer devices A to E have the same function. -It is a network form that has roles and performs equal communication. A typical service using this is Gnutella.

  On the other hand, the hybrid P2P network is a network form in which an index server for facilitating the interaction between peer devices such as PCs and mobile communication terminals as components of the network system is arranged. That is, peer devices such as PCs having a content transmission / reception function are systems that can communicate with each other via a network, and have a network configuration in which an index server as a lookup server having content storage information for content search is placed. is there. As a typical service using this configuration, for example, there is Napster. In the present embodiment, as shown in FIG. 2, index access point peers IAP1 and IAP2 having functions of an index server and an access point are arranged in each of the work spaces α and β, and a hybrid P2P network is used.

  FIG. 3 is a diagram for explaining a detection method in the work space. In the work spaces α and β, index access point peers IAP1 and IAP2 are provided. The devices that become the personal workspace peers PWA to PWE include sensors SS1 to SS5, respectively. The devices that become the personal workspace peers PWA to PWE receive infrared rays generated from the infrared ray generators arranged in the work spaces α and β via the sensors SS1 to SS5, and are stretched in the work spaces α and β. The work space is recognized by identifying the obtained ID or by measuring with a position sensor. Thereby, since it is not necessary to provide a sensor on the device side and dispose an expensive sensor in the work environment, it is possible to identify a large number of work spaces as compared with a method in which sensors are disposed in the work space. In the example shown in FIG. 3, the personal workspace peers PWA to PWC recognize the workspace α via the sensors SS1 to SS3, and the personal workspace peer PWD or PWE uses the sensors SS4 to SS5 to define the workspace β. recognize. In addition, a sensor may be provided in a device that becomes a workspace peer to recognize the workspace.

  FIG. 4 is a configuration diagram of a system according to the present embodiment. As shown in FIG. 4, the system 1 includes a workspace peer management server 2, a document management server 3, a portable device 4, a wireless LAN base station 5, an infrared generator 6, an RFID antenna built-in table 8, and a paper document with an RFID tag. 9, an index / access point server 10, a multifunction peripheral (MFP) 11, a scheduler server 12, and an access key issuing server 13. Reference numeral 30 denotes a network.

  FIG. 5 is a diagram showing the configuration of the organization activity recording apparatus. The organization activity recording device 50 includes a workspace peer management server 2, a portable device 4, an index / access point server 10, a scheduler server 12, and an access key issuing server 13.

  The workspace peer management server 2 controls the personal workspace peer PW. As shown in FIG. 5, the workspace peer management server 2 includes a personal workspace providing unit 21, a personal workspace search unit 22, a workspace integration unit 23, and an activity recording unit 24. The personal workspace providing means 21 provides a workspace for each user expressed as a document collection or a desktop space. The personal workspace providing means 21 is preferably operated on a computer that is always operating. As a result, since the workspace providing means 21 can always be accessed from a client such as the portable device 4, it is not a device that is frequently turned ON / OFF like a portable device such as a notebook PC or PDA. It can be operated on a computer that is always in operation.

  The personal workspace search means 22 detects a personal workspace recognized as existing in the same time zone and the same work space. The work space integration unit 23 integrates the work spaces detected by the work space search unit 22 to form a cooperative work space. The activity recording means 24 stores the activity in the collaborative work space in association with time and place.

  Returning to FIG. 4, the document management server 3 is a repository that stores document entities handled on various devices. A document on the document management server 3 can be specified and extracted by a URL. The portable device 4 is, for example, a notebook PC or PDA. The portable device 4 is connected to the network 30 via a wireless LAN base station 5 or a wired network (not shown). The portable device 4 is a “workspace peer PW” as an element constituting the work space. A P2P browser is installed in the portable device 4. A user who has installed a P2P browser becomes a P2P node on the network.

  The portable device 4 includes a wireless LAN antenna. In addition, the portable device 4 is provided in a device serving as a work space peer that performs communication by a hybrid peer-to-peer network, and a personal work space detecting means (infrared light receiving unit) for detecting a work space in which the device exists. 4a is provided. The wireless LAN base station 5 is a wireless LAN base station in the work space. The infrared ray generators 6 arranged in the work areas α and β transmit IDs unique to the work space. By receiving the transmission ID via the personal workspace detection means 4a, the work space where the personal workspace is located is recognized, and the existence of a set of personal workspaces associated with the device is recognized. The personal workspace detection means 4a is not limited to the infrared light receiving unit, but identifies the location of the personal workspace by recognizing the ID stretched in the work space or detecting the position. It may be a thing.

  In the work spaces α and β, RFID antennas 8a (sensors) for recognizing non-contact type IC cards (RFID cards) are arranged in the table 8 in the work spaces α and β. The RFID antenna 8a is connected to an access point server 10 disposed in each work space. RFID tags are affixed to the portable device 4 carried by the user, the user's ID card, and the paper document. These are recognized by the RFID antenna 8a disposed in the work spaces α and β.

  The index / access point server 10 transmits information about the devices existing in the work spaces α and β to other computers existing in the work spaces α and β via the network. As shown in FIG. 5, the index / access point server 10 includes multipoint work space connection means 42, area-specific work space information provision means 43, and linkage target index means 44. The multipoint work space connection means 42 mediates a connection relationship with a work space existing at a point different from the work space. The work space information providing unit 43 by area holds information on each work space by area and provides information on each work space upon request.

  The linkage target index means 44 maintains the current position of the personal workspace peer and collectively manages information regarding the location of each personal workspace. The personal workspace search means 22 can detect the position of the personal workspace and other personal workspaces existing in the same work space at the same time zone by making an inquiry to the cooperation target index means 44. A connection interface is exchanged with these personal workspace peers to form a collaborative workspace among the personal workspaces. For this reason, personal workspaces operating on various devices can be connected in an equal relationship.

  A multifunction peripheral (MFP) 11 prints a paper document 9 in response to a request from a personal workspace peer PW or the like. The scheduler server 12 can make a reservation for use of the work space. The scheduler server 12 manages a schedule table, and a user logs in to the schedule management mechanism in advance and registers in advance for a conference to participate in, for example. At this time, information on the venue and time zone is registered in the schedule item of the conference.

  The access key issuing server 13 issues an access key according to the context of the work space. The functions provided by the document management server 3, the portable device 4, and the index / access point server 10 are realized on JavaServlet (Java: registered trademark). Communication between these servers is realized by exchanging messages in XML (Extensible Markup Language) format. The index / access point server 10, the portable device 4, and the document management server 3 are independent, and messages can be exchanged between arbitrary servers. In various devices, a peer-to-peer framework represented by JXTA or the like is executed. This makes it possible to form a peer-to-peer network between various devices. Further, by communicating with each other between the peers, the information held by each peer can be synchronously shared between the peers. In other words, peer-to-peer file sharing can be performed.

  Next, the structure of data processed by the software of this embodiment will be described. First, the data structure in the personal workspace peer will be described. 6 and 7 are diagrams showing a data structure in the personal workspace peer. The software operating on the personal workspace peer holds the “personal workspace 131” data having the structure shown in FIGS. 6 and 7, and performs processing of a procedure described later. The personal workspace 131 includes a peer ID, a current location ID, an owner, and a current access point.

  FIG. 8 is a diagram showing a data structure in the index access point. The software operating on the index / access point peer IAP holds the “index / access point 141” data having the structure shown in FIG. The index access point 141 includes a peer ID, an address, a current position ID, an access point name, and a connection destination designation UI address.

  Next, a message flow for detecting a peer in the same work space will be described. FIG. 9 is a flow for detecting peers in the same work space. It is assumed that personal workspace peers PWA to PWE exist in the work space α. The RFID antenna 8a installed so as to be embedded in the table 8 in the work space α is in a state of waiting for recognition of an RFID tag attached to a notebook PC, ID card, or paper document carried by the user. When an RFID tag is detected by the RFID antenna 8a, or when a tag that has existed until then is not detected, the personal workspace peer PWA sends an “object detection message 161” having a format as shown in FIG. Generate. This “object detection message 161” is detected by “message ID (messageid)”, “transmission date / time (datetime)”, “source access point peer ID (originated)”, “detection / non-detection flag (status)”. And “object ID (objectid)”. The “detected / non-detected flag (status)” is set to “detected” when a new object is detected, and “undetected” when no new object is detected.

  The personal workspace peer PWA sends an object detection message 161 to the personal workspace peer PWB. The personal workspace peer PWB generates an “object detection transfer request message 162” having the format shown in FIG. Here, the “object detection transfer request detection message 162” includes “message ID (messageid)”, “transmission date / time (datetime)”, “source access point peer ID (originated)”, “detection / non-detection flag (status) ””, “Object ID (objectid)” regarding the object detected by the source access point peer. The personal workspace peer PWB sends the generated object detection transfer request message 162 to the personal workspace peer PW3. In contrast, the personal workspace peers PWB and PWC generate a cooperative peer response message and send it to the personal workspace peer PWA.

  Also, when the personal workspace peer PWA sends the object detection message 161 to the personal workspace peer PWD, the personal workspace peer PWD generates an object detection transfer request message 162 and sends it to the personal workspace peer PWE. Upon receiving the object detection transfer request message 162, the personal workspace peer PWE generates a coordinated peer response message and sends the coordinated peer response message to the personal workspace peer PWA. As a result, the personal workspace peers PWA to PWE are detected in the work space α.

  Next, a message flow relating to connection with a remote location will be described. FIG. 12 shows a message flow regarding connection with a remote location. Assume that an index access point peer IAP1 and personal workspace peers PWA and PWB exist in the workspace α, and an index access point peer IAP2 and personal workspace peers PWC and PWD exist in the workspace β. The RFID antenna 8a installed in the form embedded in the table 8 of each work space α, β is in a state of waiting for recognition of the RFID tag attached to the notebook PC, ID card, or paper document carried by the user. When an RFID tag is detected by the RFID antenna 8a or when a tag that has existed until then is no longer detected, the index access point peer IAP1 in the work space α has a format as shown in FIG. An object detection message 161 "is generated.

  The index access point peer IAP1 performs “object detection message 161” transmission processing, and the “remote access point peer reference” held in the “remote access point peer reference set” held by the index access point peer IAP1 described above. The “object detection transfer request message 162” shown in FIG. 11 is generated for the access point peer AP2 in which “true” is set in the “state” of “”.

  The index access point peer AP1 sends an object detection message 161 to the personal workspace peers PWA and PWB, and sends a workspace peer detection transfer request message 162 to the index access point IAP2 in the workspace β. When receiving the “object detection transfer request message 162” from the index access point peer AP1, the index access point peer AP2 generates an “object detection message 161” including the object ID included in the message, The generated “object detection message 161” is transmitted to all the personal workspace peers PWC and PWD representing the devices that are recognized as the remote access point peer existing in the same workspace. As a result, the personal workspace peers APA to APD are detected in the work spaces α and β.

[Discover peers to be linked]
FIG. 13 is a processing flowchart of discovery of a peer to be linked. Each room is provided with an infrared transmitter 6 that transmits the ID of the current position using infrared rays. The infrared light receiving unit incorporated in the portable device 4 serving as the personal workspace peer PW receives the current position ID and recognizes the current position (step S101). In each user's personal workspace peer PW, the ID of the detected current position is registered in the “current position ID” of the personal workspace peer, and the index / access point server 10 existing in each work space The peer ID is notified (step S102). Here, the network address of the index / access point server 10 to be notified is managed as an address specified by the current position ID. For example, the position ID is expressed as an IP address.

  The index access point server 10 holds the “current peer set” of the index access point 141 with the information on the peer ID reported above. In the personal workspace peer PW, a new “shared document history 134” is generated in the “shared document history set”, the date and time at that time are registered as “start date and time”, and the ID of the current position is registered as “position ID”. (Step S104). The personal workspace peer PW searches the personal workspace peer PW existing in the same workspace by making an inquiry to the index / access point server 10 existing in the workspace (step S105).

  At this time, the personal workspace peer PW registers the peer ID of the corresponding personal workspace peer in the “cooperative personal workspace set” of the personal workspace (step S106). The search is a P2P type search. That is, first, all peers on the subnet are searched, other subnets connected by the gateway peer are searched, and those found are reported to the search request source.

[Workspace creation and document sharing]
FIG. 14 is a process flowchart in document sharing. FIG. 21 is a personal workspace user interface 201. The personal workspace UI 201 is shared between the “personal document file list 203” for displaying a list of files personally owned by the user and other personal workspace peers PW existing in the same place. The “shared document file list 204” is a list of documents to be processed. Here, the file group listed in the “personal document file list 203” is stored on the document management server 103.

  When a file displayed on the “personal document file list 203” is selected on the personal workspace UI 201 and dragged and dropped onto the “shared document file list 204” (step S201), the document is shared. The address of the document is registered as a document in the shared document space (step S202). As a result, new shared document 135 data is generated and registered in the “shared document set” of the current shared document history 134 (step S203). At this time, the address (URL) of the shared document and the document type of the shared document are registered.

  Simultaneously with the above processing, information on the shared document is shared in real time with the personal workspace peer PW held by the personal workspace peer PW in the “collaborative personal workspace set” (peer-to-peer In the personal workspace peer PW that has received the shared document information, information related to the shared document is stored in the “shared document set” of the current shared document history 134. The data of the new shared document 135 is generated and registered.

  When an RFID tag attached to a paper document or electronic paper is recognized by the RFID antenna 8a placed in the work spaces α and β, it is stored in advance on the document management server 3 corresponding to the ID tag. Take out the electronic document and register it as a shared document. This correspondence relationship is that the document to be printed is automatically saved in the storage in the multifunction device 11 when copying or a print is instructed via the network, and the same ID as the output document is assigned. It is realized by doing. The assigned ID includes the stored address of the multifunction machine 11, and an electronic document is acquired using the address.

[Connection with remote location]
FIG. 15 is a processing flowchart when connecting to a remote location. An access point server 10 representing each work space is installed in each work space α, β. The personal workspace peer PW searches the P2P network for a “current access point” related to the current workspace in which the personal workspace peer PW exists (step S501). A user interface (Java applet (Java: registered trademark)) for specifying a connection destination provided by the current access point is called (step S502). A connection destination is selected from the past connection destination list held in the personal workspace 131 of the user (step S503). When a connection destination is specified, the result is added to the local connection list history of the personal workspaces of all users existing in the work space.

  When the user selects a connection destination or inputs a new connection destination URI, the access point server 10 corresponding to the connection destination is searched on the network 30 (step S504). The access point server 10 searches the P2P network at regular intervals, and holds peers (personal workspaces that currently exist in the work space covered by the access points) that are found in the same context.

  When sharing a document, the personal workspace peer PW shares information about the shared document with a peer held by another access point connected to the current access point as a peer under the same context (step S505). Specifically, change information is propagated between the access point servers 10.

[Access to documents based on context]
FIG. 16 is a processing flowchart when accessing a document based on a context. The user can associatively retrieve a document through the personal workspace UI 201 shown in FIG. In the personal workspace UI 201, past contexts stored in the shared document history set stored in the personal workspace peer PW are listed in the “context list 206” in time series (step S601). When an arbitrary context is selected from these (step S602), information on the corresponding context is displayed (step S603). Here, the information related to the context includes the date and time, the place, the document set related to the selected context, the participant set at that time, and the like.

  On the other hand, when a document shared in the past context is accessed on the personal workspace UI 201 through the above procedure, the date and time of accessing the document and the email address of the accessing user are registered as an access history. (Step S604). Thereby, privacy is maintained. The access history for each document can be displayed by calling up the access history list view.

[Human Network View Display]
FIG. 17 is a flowchart of a human network view display process. FIG. 22 is a diagram showing a human network display user interface 301. When “personal network diagram 212” is selected from the pop-up menu of the context history list of the personal workspace UI 201 shown in FIG. 21 (step S701), based on the user set stored in the shared document history 134, the past time The frequency of the collaborative work per unit is measured, and the strength between users is calculated based on the frequency (step S702). The result is displayed as a human network view 302 in which a face photograph icon as shown in FIG. 22 is looked down like a network (step S703). FIG. 22 shows that the stronger the strength, the shorter the link length.

  When an icon of an arbitrary user is designated on the overhead view, a conference context list view 303 in which the user has participated is displayed (step S704), and when a context is designated from the conference context list view 303, the personal workspace UI 201 shown in FIG. The information regarding the designated context is displayed (step S705).

[Display Group Awareness]
FIG. 18 is a flowchart of group awareness display processing. FIG. 23 shows a group awareness user interface 401. When the “member activity status list 207” button of the personal workspace UI 201 shown in FIG. 21 is selected (step S801), the member registered in “group member 133” held by the personal workspace peer PW becomes the owner. An overhead view as shown in FIG. 23 is displayed from the “current position” of the existing personal workspace (step S802). This makes it possible to grasp the work status of other users.

[Context exchange by e-mail]
FIG. 19 is a flowchart of context exchange processing by electronic mail.
FIG. 24 shows an e-mail transmission user interface. When the shared document history 134 is generated, a Web page corresponding to the shared document history 134 is automatically generated (step S901), and can be accessed via a Web browser.

  When a context is designated from the context list 206 on the personal workspace UI 201 shown in FIG. 21 and “E-mail 211” is selected from the pop-up menu, the address of the generated Web page is changed to the text as shown in FIG. An e-mail message window 501 included therein is displayed, and the user sends this mail sheet (step S902). The recipient can access the corresponding Web page by displaying the URL included in the received mail sheet (step S903).

[End of collaborative work]
FIG. 20 is a flowchart of the end processing of the cooperative work. When the work space recognized by the sensor incorporated in the portable device 4 changes, it is recognized as the end of the context (step S1001). Context fragments are generated as Web pages and output on the Web server (step S1002). Login to the scheduler, and the address of the Web page output to the Web server in the corresponding time zone on the scheduler is registered (step S1003). If there is already a reservation, add it to the comment field. If there is no reservation, create a new entry and add it.

  FIG. 25 is a diagram showing a user interface 701 on the calendar system. When “calendar 210” is selected on the “context history menu” on the service activation user interface 220 shown in FIG. 21, a calendar view 701 as shown in FIG. 25 is displayed. On the calendar view 701, past contexts are displayed on the calendar based on the “date and time” field and the “location” field in the “context” data. The left half of the calendar view 701 is a “monthly view 702” displayed in units of months, and the right half is a “daily view 703” displayed in units of days. When the user selects a context displayed on the daily view 703, the date / time, shared document, participant, venue, and captured video information related to the context of the selected date / time is in a format as shown in FIG. By selecting a participant or a shared document, detailed information about them can be obtained.

  When “e-mail 211” is selected on the “context history menu” on the service activation user interface 220 shown in FIG. 21, an e-mail message window 501 as shown in FIG. 24 is displayed. In the body part of this message, the URL of the context snapshot (stored in the “snapshot” field of “context”) that was previously output in HTML format on the Web server is automatically written in the message body. The user inputs the destination and the title of the message and presses the send button to send the message to the destination.

  On the other hand, on the receiving side of the message, by clicking on the URL of the context fragment written in the message main pair, information related to the context can be viewed and the shared document can be taken out.

[Workspace sharing process that connects remote workspaces]
The access point peer AP1 installed in the work space α has the appearance as shown in FIG. 26 for setting the work space sharing with the work space existing in the remote place such as the work space β. A destination setting screen 801 "is provided. In this screen, a set of remote access point peer APs as connection candidates held in “connection destination 142” of “access point 141” having the data structure shown in FIG. It is displayed on the "list" and "on the connection destination list", and the user specifies the connection destination that shares the work space, and when the "connect button" is pressed, the specified "remote access point peer reference" True is set in the “connection state” of “medium” and stored as a connection destination.

  Further, when the connection target is not displayed on the list, when “add” is selected on the pop-up menu on the “connection destination list”, a “remote connection destination registration window 901” as shown in FIG. 26 is displayed. Through the window, the “location”, “workspace name”, and “connection destination” of the access point peer that is a connection candidate are registered.

  Further, the organizational activity recording apparatus 50 shown in FIG. 5 has the following functions other than those described above.

[Diversity of workspaces]
First, the diversity of workspaces will be described. The workspace managed by the personal workspace providing means 21 is, for example, a personal desktop environment. The desktop environment of each personal workspace peer is divided into an area operated by an individual user and an area shared among a plurality of other users existing in the same time zone and the same work space. The workspace integration means 23 constitutes a shared desktop environment in which operations can be shared among a plurality of personal workspace peers. As a result, data and operations on the shared area are shared with other workers in real time. Therefore, a collaborative work environment can be formed by synthesizing a desktop environment brought by a plurality of users in an actual work environment.

The workspace managed by the personal workspace providing means 21 is, for example, a set of files managed by the individual. A file set managed by a personal workspace peer is composed of a document file group owned by the individual user and a document group shared among a plurality of other users existing in the same time zone and in the same work space. . The workspace integration means 23 constitutes a shared file set that can share files among a plurality of personal workspace peers. As a result, information on the shared document group is shared with other users in real time. Therefore, it is possible to form a space for sharing a document group brought by a plurality of users in an actual work environment.
[Recognition of personal workspace in workspace]

  Next, recognition of the personal workspace in the work space will be described. The personal workspace peer is associated with an identifier that can be recognized by a sensor such as a device ID or ID card. The RFID antenna 8a detects the ID of the personal workspace peer PW. The personal workspace detector 41 of the access point server 10 connected to the RFID antenna 8a passes the network where the personal workspace peer PW is detected with respect to the personal workspace peer PW specified by the detected ID. Notify at. Each personal work space peer PW receives the location information sent from the access point server 10 and recognizes the work space in the real space where each work space currently exists. Thereby, a target object can be identified reliably.

  Instead of the RFID antenna 8a, a biosensor installed in each work space may be used. The work space provided by the personal work space providing means 21 is associated with each user. The biometric sensor sends the user's biometric features such as each user's fingerprint, face, retina pattern, voiceprint, hand shape, and face temperature distribution to the personal workspace detection means. The personal workspace detection means 41 recognizes the existence of the personal workspace peer associated with the feature quantity on each user's living body based on the feature quantity on the living body, and the personal workspace peer is detected. Notify the location via the network. The personal workspace peer receives the location information sent from the personal workspace detection means 41 and recognizes the work space in the real space where the respective workspace currently exists. Thereby, it is possible to identify a work space associated with a human without carrying around an ID card or a portable device.

  The location of the workspace provided by the personal workspace providing means 21 can be identified by the user by explicitly specifying the location to the personal workspace search means 22. Therefore, since it is not necessary to arrange the sensor in the work space, an inexpensive configuration is possible and the sensor can be used even in a place where it is difficult to install the sensor.

  The location of the workspace provided by the personal workspace providing means 21 is associated with the location of the device. The user explicitly specifies the existence of other devices existing at the same location to the personal workspace search means 22. For example, the user designates a device for which a linkage relationship is to be set by selecting a device to be linked from a list. Information regarding personal workspace peers existing in the same workspace is shared and propagated between the personal workspace peers, and a group of personal workspace peers existing in the same workspace can be recognized. Thereby, since it is not necessary to arrange | position a sensor in a work space, while being able to comprise an inexpensive structure, it can utilize also in the place where it is difficult to install a sensor.

[Collaboration and synthesis of security-safe workspaces]
The access key issuing server 13 issues a unique access key corresponding to each context. When the personal workspace is recognized by the personal workspace search means 22, an access key corresponding to each context issued by the access key issuing server 13 is sent to the personal workspace providing means 21 of the personal workspace. . The workspace integration unit 23 performs management as a collaborative work space that collates access keys and integrates personal workspaces. As described above, the setting of the linkage relationship is limited only to the workspace management mechanism recognized in the same work space (including a case where the remote workspaces are connected). Workspaces that exist in the same workspace because access keys (credentials) associated with contexts (the same workspace in the same time zone) are issued to each workspace management mechanism and collated when setting up the linkage It is possible to perform secure cooperation by limiting the cooperation to the only person.

  The scheduler server 12 is used by a user to log in in advance and make a work space reservation. The scheduler server 12 manages the schedule table. A user logs in to the scheduler server 12 in advance and registers in advance for a conference to be attended. Information on the venue and time zone is registered in the meeting schedule table. When the workspace is recognized by the personal workspace search unit 22, the workspace integration unit 23 makes an inquiry to the scheduler server 12 by the owner of the recognized personal workspace and uses the time zone and the workspace. Check if you have a reservation. The workspace integration unit 23 integrates the personal workspace only when the user reserves the use of the time zone and the work space. Therefore, by reserving the time zone and place to be used in advance, integration with unscheduled personal workspaces can be suppressed and a secure collaborative workspace can be formed.

  The work space integration means 23 issues a password relating to the use of the work space in the time zone scheduled in advance by the user. For example, a one-time password associated with time and place is issued to the prospective participants. The work space providing means 21 holds the password. When the workspace is recognized by the personal workspace search unit 22, the workspace integration unit 23 checks the password held by the recognized personal workspace providing unit 22, and if there is no problem, the personal workspace is searched. To form a collaborative work space. For this reason, a password that is valid only at the reserved time and location that is associated with the time zone and location to be used is issued, so it is possible to suppress cooperation with unplanned workspaces and secure cooperation Can be done.

The workspace integration means 23 calculates and holds the reliability between the workspaces based on the past integration history of the workspaces. The workspace integration unit 23 does not perform authentication processing when linking with a personal workspace having a reliability level equal to or higher than a threshold value, and performs authentication processing when integrating with a workspace having a reliability level equal to or lower than the threshold value. To do. As a result, based on the trust relationship established based on the results of past collaborative work, authentication is omitted for linkage with a personal workspace with a strong trust relationship, and between personal workspaces with weak trust relationships. It is possible to prevent the user from requiring excessive authentication processing by performing authentication for the cooperation in.
[Effective linkage setting]

  The workspace integration unit 23 holds, in the cache, the address of the workspace peer related to the workspace integrated in the past for each work space. When the personal workspace is authenticated by the personal workspace search unit 22, the workspace integration unit 23 checks the address held in the cache and searches for the workspace peer to be linked before searching the network. Check the address of. Thereby, since it is not necessary to search for personal workspaces in which a cooperative relationship is frequently set in the work space on the network every time they are linked, the cooperative relationship can be set at high speed.

The workspace integration means 23 holds the address of the personal workspace peer related to the workspace integrated in the past in association with the features of the context (member structure, date / time, location). When the workspace is authenticated by the personal workspace search unit 22, the workspace integration unit 23 checks the address held in association with the context before searching the network and searches for the personal work to be linked. Check the address of the space peer and set the linkage. As a result, in the case of daily connection between multiple workspaces, or in situations where users frequently use workspaces, personal workspace peers that are frequently linked under a certain context Since there is no need to search on the network every time, the linkage relationship can be set at high speed.
[Workspace connection interface format]

The workspace providing means 21 describes the workspace connection interface as an attribute relating to an input / output channel composed of video input / output, audio input / output, and operation event. The workspace integration unit 23 integrates workspaces by performing protocol conversion and format conversion based on the workspace connection interface. For this reason, wide-area and open collaborative workspaces can be formed by connecting video and audio communications on personal workspaces and operation events on collaborative workspaces according to a unified connection format.
[Context segmentation]

  The personal workspace search means 22 treats the time zone in which each individual workspace peer was present in the workspace as the context start / end time for the personal workspace peer. That is, the personal workspace search means 22 treats each workspace as a context from the time when it enters the workspace and is recognized until the exit time. For this reason, since only the time when the workspace existed in the workspace can be treated as the context for each, the context cutout can be managed individually, and the members can be switched in a long meeting. However, each user can extract and manage only the context of the part related to him. The activity recording means 24 records the history of the context for each user by using the detected context as a unit.

  The personal workspace search means 22 calculates a time period from the time when any personal workspace peer is first recognized in the workspace until all the personal workspace peers are not recognized, to the personal workspace. Treated as context start / end time. That is, the personal workspace search means 22 treats from the time when the detection target (personal workspace) first enters the room to the time until the user who finally leaves as one context. For this reason, even if a user leaves in the middle, he can share the context until all other members leave. The activity recording means 24 records the history of the context with the detected context as a unit.

  The scheduler server 12 is for a user to make a use reservation in advance. The personal workspace search means 22 collates the time when the personal workspace is recognized in the work space with the time zone registered in the scheduler server 12, and there is a large difference between the scheduled participant and the detection start time and the detection end time. When it is not seen, the time zone registered in the scheduler server 12 is treated as the context start time and end time for the personal workspace. In this way, by using the start time and end time related to the work space registered in the schedule item in the schedule table registered in advance when the context is cut out, the entry / exit time of the user is somewhat Even if there is a difference, the start time and the end time of the context can be corrected according to the time registered in the schedule table. The activity recording means 24 records the history of the context with the detected context as a unit.

  The personal workspace search means 22 cuts out a time zone at the time when a large change is seen in the workspace recognized in the workspace, and handles it as the context start and end times for the workspace. That is, the personal workspace search means 22 recognizes that it is the context switching time when a certain change occurs, and starts and ends the context based on the change of the user set and the component set. Is identified. For this reason, even if some members overlap in a continuous meeting, if a situation in which the majority of participants' members are replaced is detected, the user can It can be recognized as another context without leaving. The activity recording means 24 records the history of the context with the detected context as a unit.

The personal workspace search means 22 records personal workspaces recognized in the workspace in detail, and hierarchically structures events such as conference start / end, device use start / end, and participant movement. And save it as a context for the personal workspace. In this way, contexts are segmented hierarchically based on events that occur, and contexts are organized hierarchically based on presenter switching, document switching, participant entry / exit, and the like. The work history is carefully extracted based on these hierarchical contexts. For this reason, when searching for a shared document, a participant, or the like based on the history of the context later, it is possible to take out a change in the detected small context as a clue. The activity recording unit 24 records the history of the context with the context detected in this way as a unit.
[Extract abstract context]

  The personal workspace detection means 41 determines the formal degree of the meeting from the number of participants, the organization to which the participant belongs, and the position detected in the workspace, and adds it as additional information constituting the context information. Using this information, a past context is searched from the context history. For this reason, when searching for a past context from the context history, it is possible to search using the formal degree of the conference.

  The personal workspace detection means 41 discriminates the meeting body (management meeting, management board, etc.) from the date and time, the place of the meeting, the number of participants, the organization to which the participant belongs and the position detected in the workspace, and the context information. Is added as additional information that constitutes. Using this information, a past context is searched from the context history. For this reason, when searching for a past context from the context history, it is possible to search using the name of the conference body.

  The personal workspace detection means 41 combines information recognized in the actual workspace (participants, places, etc.) and information recognized in the digital world (documents used, software, etc.) Extract context about detailed activities. Using this information, a past context is searched from the context history. For this reason, when searching for past contexts from the context history, more detailed activity content is detected by combining information detected as real-world events with information detected by computer operations. The result can be used for context search. For example, a keyword vector is extracted from the content in the electronic document being used to grasp the content of the meeting, the participants are associated with the keywords, and a link is set between similar contexts.

[Formation of work space between multiple remote locations]
Next, the formation of a work space between a plurality of remote locations will be described. The multipoint work space connection means 42 mediates a connection relationship with other work spaces. The workspace integration unit 23 exchanges identification information (address or ID) related to the workspace recognized in the workspace with the other workspaces in the connection relation through the multipoint workspace connection unit 42. Integrate workspaces as if they were in the same workspace. Specifically, when a device existing in each work space is connected to the access point server 10 in each work space, information on the personal work space existing in the work space via the multipoint work space connection means 42. Are shared in real time, and the user's workspace existing in the workspace is integrated to form a collaborative workspace. For this reason, a plurality of work spaces existing at remote locations are connected to form a virtual work space, and the work recognized in the work space as if it were in the same work space. Space can be integrated.

  The work space information providing unit 43 by area holds information on each work space by area and provides information on each work space. The workspace integration unit 23 makes an inquiry to the area-specific workspace information providing unit 43 based on the connection destination workspace name specified as a hierarchically structured name, and sets the other workspace as the connection destination. Identify the corresponding workspace integration means, exchange identification information (address or ID) on the workspace recognized in the remote workspace, and collaborate the workspace by integrating the personal workspace between multiple remote locations Form. As a result, a plurality of work spaces that exist in remote locations are connected to form a virtual work space, and the work recognized in the work space as if it existed in the same work space. Space can be integrated. The workspace name is managed with a hierarchical name corresponding to the location range, and there is a peer (a function similar to a name server) that caches information related to the peer group in each location range. Sometimes, peers that exist in remote locations are identified by querying those workspace peers.

  The workspace integration means 23 and the multipoint work space connection means 42 are linked with an existing communication system such as a telephone or a TV conference system. In this communication system, the connection of the communication line with the communication partner starts. The personal workspace identification information (address or ID) is exchanged between the connected workspaces via the workspace connection means, and one or a plurality of personal workspace peers existing at remote locations are exchanged. As well as cooperating as if they existed in the same workspace, information on documents shared between the personal workspaces in the connection relationship is sequentially exchanged and shared via the multipoint workspace connection means 42 .

  As described above, when the user calls the other party using the telephone or the TV conference system, or when the user calls the other party, the access point of the transmission source (workspace connection The connection relationship between the access points is automatically set between the access point and the destination access point, and information on shared documents is shared in real time between personal workspaces at remote locations via the access point. By doing this (when there is a change, the result is notified), it is possible to form a collaborative work space connecting a plurality of personal work spaces existing in remote locations. Thus, at the start of connection with a remote location, using the function of the access point, even if the connection relationship with the remote access point is not explicitly set, the connection partner is called with a telephone or a TV conference system. Alternatively, a cooperative work space can be formed between work spaces by being called.

  The multipoint work space connection means 42 is linked with an existing communication system such as a telephone or a TV conference system, and the multipoint work space connection means 42 at the connection point is linked from the time when communication with this communication system starts. Form. Each multi-point work space connection means 42 is used to connect the ID set of the personal workspace peer existing in the work space targeted by each multi-point work space connection means 42 with the remote work space connection means in connection relation. Share in real time (if there is a change, the result will be notified). In addition, each multipoint workspace connection means 42 includes IDs of personal workspace peers existing in remote workspaces that are connected to each other in the workspace targeted by the multipoint workspace connection means 42. Notify your personal workspace peers (notify whenever changes occur). Furthermore, the workspace integration means 23 possessed by each individual workspace peer is based on the set of IDs related to the remote personal workspace peers notified from the multipoint workspace connection means 42 and the remote personal workspace peers. Exchange and share information about shared documents directly.

  As described above, when the user calls the other party using the telephone or the TV conference system, or when the user calls the other party, the access point of the transmission source (workspace connection The connection relationship between the access points is automatically set between the access point and the destination access point, and information on the set of personal workspace peers existing in each workspace is shared in real time. Information about the personal workspace at a remote location is notified to the personal workspace peer in the workspace covered by each access point or to the personal workspace index. As a result, when starting a connection with a remote location, even if the connection relationship with the remote access point is not explicitly set, the connection partner is called or called by the telephone or the TV conference system. Collaborative work spaces can be formed between spaces.

  The multipoint work space connection means 42 holds a history of the multipoint work space connection means that have become connection destinations in the past, and displays a list of the past connection destinations at the time of connection and selects connection destinations. Enable. Thus, the user can immediately specify a work space with a high frequency of joint work without checking the name or address of the connection point as the connection destination.

  The multipoint work space connection means 42 is a group of users recognized in the joint work space when the joint work is performed by connecting to a remote place. A multi-point work space corresponding to the work space in which the current location of users with strong relationships (users who have collaborated frequently) is searched and found on the network. A list of connection means can be presented and designated as a connection destination. As a result, the user can immediately specify the work space as the connection destination without checking the name or address of the connection point as the connection destination.

  The activity recording means 24 associates an image written on a whiteboard, a video taken by a still camera, a video camera, an audio recorded by a microphone, and the like in a work space with a shared context (date and time and place). Record. It can be accessed later from the context history. For this reason, information newly generated using a device installed in the work space, a conversation, or the like is associated with a context, stored as a shared document, and can be reused by searching from the context history.

  The activity recording unit 24 records annotations on a document edited on an information processing apparatus such as a PDA or a notebook PC in association with a personal context in the work space, and can be accessed later from the history of the context. . As a result, information newly generated using a device possessed by the user, conversation, and the like can be associated with the context, stored as a private document, and reused.

  The activity recording means 24 records the document scanned by the scanner in association with the personal context in the work space, and makes it accessible later from the history of the context. Accordingly, the scan image of the book or document input from the scanner is associated with the context, stored as a private document, and can be reused by searching from the context history.

  The activity recording unit 24 stores information disclosed by an information presentation device (bulletin board, reception of destination, etc.) installed in the work space in association with a private context. The visual information presentation device transmits an ID related to the information being presented, acquires the ID, puts the ID in the workspace (individual workspace or shared workspace), and the current date and time (context). The data can be stored in association with each other, and can be accessed later by the user based on the stored date and time. Thereby, the information displayed on the information bulletin apparatus installed in the work space is associated with the context, stored as a private document, and can be reused by searching from the context history.

  Paper documents and electronic paper hold readable IDs. The ID or address of the electronic document associated with the paper document or electronic paper is assigned to this ID at the time of printing. When the ID is recognized in the work space, the activity recording unit 24 records the electronic document corresponding to the ID in association with the context at that time. As a result, paper documents or electronic paper are recognized in the work space, and electronic documents corresponding to them are saved as shared documents under the context, and can be reused by searching from the context history. Can do.

  The workspace integration unit 23 sets mutually fixed links for users and documents existing in the same context (same time zone and same work space). Users can access information on documents and users associatively by following these links. Thus, since a link is automatically set between the document and the user, it is possible to promote contact with other users later using the document as a key.

[Promoting access to and reuse of activity-based activities]
Access and reuse of activities is promoted as follows. The activity recording means 24 displays, as a user interface for searching the context history, a list of thumbnails of documents shared on the workspace at that time for each context. Thereby, when searching for a context to be accessed from the context history, it is possible to assist visually recalling a group of documents used under the same context from the document layout.

  The activity recording means 24 displays, as a user interface for searching the context history, a list of the participant's face photograph at that time or the seat arrangement in the work space for each context. This assists in recalling the target context from the face image of the participant when searching the context to be accessed from the context history.

  The activity recording unit 24 displays, as a user interface for searching the context history, a photograph of the work space at the place where the work is performed or a photograph taken during the work for each context. This assists in recalling the target context from the image in the workspace when searching for a context to be accessed from the context history.

  The activity recording means 24 provides a search function that allows a set of events accumulated during collaborative work to be displayed and viewed as a hierarchical relationship as a user interface for searching the context history. A search is performed based on a set of events accumulated in a hierarchical manner, and a target material is specified. For example, if presenters and speakers at the podium are recorded in detail, it is possible to search based on those events. As a result, when searching for a context to be accessed from the context history, it is supported to recall a target context based on various events that occur during the detectable work.

  The activity recording means 24 records, as a user interface for searching the context history, the position of the participant (sitting position, podium position, etc.) in the work space, the position of the screen on which the material is presented, and the like. Later, when the user searches for a context, the relationship is displayed along with a temporal change in association with a diagram of the workspace. As a result, when searching for a context to be accessed from the context history, the purpose is based on information on the spatial position of the participant, such as the position of the participant's seat at the time of collaborative work, and the presentation position of the material. Can assist in recalling the context.

  The activity recording means 24 can list the history of the context in the form of a schedule table as a user interface for searching the context history. The user can select a context displayed in the schedule table and access various information related to the context. As a result, the context history is displayed in time series as a calendar, and it is supported to recall the target context based on the user's temporal memory.

  The activity recording unit 24 outputs the fragment of the context on the Web server in the HTML format, and in the existing schedule management system that the user uses on a daily basis, as a schedule item corresponding to the date and time of the context, The URL of the output HTML document is automatically registered, and information related to the context can be accessed from the schedule management system. As a result, the information related to the context in the actual work space can be accessed from the existing schedule management system, so that the user does not switch the schedule management system used so far to another system, Can be used.

  For each target (document, user, work space, etc.), the activity recording means 24 holds a context corresponding to the date and time when the target existed, and displays a list of contexts related to the selected target. indicate. By selecting a context from the list, it is possible to access various information related to the context. Thereby, the related past information can be associatively extracted by extracting the context history given to the object.

  The activity recording means 24 calculates the strength of the relationship between users based on the frequency of collaboration between users in the workspace, the frequency of document exchange, the direction of document provision / provided relationship, etc. Display it as a human network view. Furthermore, when a user is designated on the overhead view display, a history of past contexts in which the selected user is involved is displayed, and various information related to the contexts can be accessed. As a result, the activity status in the organization can be grasped based on the relationship between users, and the reuse of information resources can be promoted as a memory held and managed by the entire organization.

  The activity recording unit 24 obtains a distance of similarity between the contexts based on a keyword set included in a document group handled in each context, and displays a bird's-eye view, thereby allowing access to contexts with high relevance. As a result, it is possible to grasp the situation related to activities in which the same activity is performed in the organization based on the similarity between documents, and to promote the reuse of information resources as a memory held and managed by the entire organization.

  The activity recording means 24 outputs the context fragments to the Web server in the HTML format, records important contexts (predetermined contexts) as a set of bookmarks, and can call them immediately when necessary. . Thereby, it is possible to call a frequently referred context in the context recorded / stored in the context history by a simple operation and to access information related to the context.

  The activity recording unit 24 outputs the context fragment to the Web server in the HTML format, and outputs the context fragment output on the server to the ID of the electronic paper or paper document having the writable ID. The past context can be called by associating and recognizing the address. As a result, among the contexts recorded and stored in the context history, the frequently referred contexts can be carried around in the form of printed materials that do not require power consumption, or can be instantly targeted using the readability of paper documents. In addition to being able to identify the context to be performed, information on the context can be immediately accessed.

  The activity recording means 24 is based on a set of users in the current context (time and place) or feature quantities (keyword set etc.) extracted from the shared document, work place, date and time (day of week, time zone, etc.). List similar contexts and access various information about them. As a result, past contexts in the same situation as the current one can be easily accessed, so in the case of a meeting that is held by the same member at the same time in a regular case, the context related to the previous meeting is immediately searched without searching. It can be taken out.

[Awareness of activities beyond the organizational framework]
The activity recording means 24 outputs the context fragment to the Web server in the HTML format, and allows the address (URL) of the context fragment to be exchanged by transmitting / receiving as an email of the electronic mail system. As a result, information related to the context can be exchanged and accessed among many users, including users who have not participated in the work under the context.

  The activity recording means 24 generates topics on the bulletin board system and discussion threads of an asynchronous discussion system for the context stored in the context history, and performs an asynchronous conversation related to the context, Allows registration of materials. As a result, after the discussion conducted in real time, the discussion can be performed asynchronously and follow-up, or the minutes and related materials can be added.

  The activity recording means 24 automatically associates the participating user with the communication means for the participating user in relation to any past context stored in the context history, and automatically clicks the user to click the communication means. Can be called. Thus, by designating a participating user, a mail sheet of the e-mail system is automatically opened, and an e-mail can be transmitted or a telephone conversation can be automatically made.

  The activity recording unit 24 displays information regarding the current context regarding a set of users registered in advance or a set of highly related users, or when there is a change in the context. As a result, it is possible to obtain awareness regarding the current work situation regarding the member to which the user is related.

  The activity recording unit 24 automatically sets or cancels the cellular phone held by the user to the answering machine mode according to the context. Thereby, it is possible to prevent the conference from being interrupted by telephone when the conference is in progress.

  The activity recording means 24 warns an alarm when there is a discrepancy between the current group and a member of the same group. Thereby, for example, when a meeting to be attended has been forgotten, it is possible to call attention to the user.

The activity recording means 24 extracts feature values by keywords from a group of documents shared in each context, forms a transition vector of a time-series keyword set, and compares them among a plurality of contexts, so that future interests can be obtained. The group that seems to be common can be noticed each other. As a result, it is possible to obtain an awareness of the existence of other members handling similar contents.
[Privacy Management]

  The personal workspace providing means 21 designates the disclosure range when the personal workspace is published on the network in advance as a set of users, and restricts the use to only the designated users. In this way, for each user, the range in which his / her presence is disclosed can be set individually by the user. Furthermore, it can be set in association with each context. As a result, it is possible to prevent privacy related infringement by accessing information on the location and activities of individual users by an unspecified number of users or unexpected users.

  The work space providing means 21 retains information on the user who has accessed the work space as a history, and browses or displays the access record at a time required by the user. A history of access by other users to the location of the user or the document provided by the user is maintained, and the user can check the access history at any time. When accessed, the fact is fed back to the user in real time. Thereby, it is possible to know whether the information provided / disclosed by the user is not accessed by an unexpected user, and the disclosure range can be grasped to some extent.
