## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to data control, and more particularly, to a data control system that controls data such as documents with a database and presents the controlled data upon a user's request. The present invention further relates to a method of controlling data used in the data control system, a computer program that causes a computer to operate as the data control system, and a program product in which the computer program is stored.
2. Description of the Related Art
Japanese Laid-Open Patent Application No. 2004-56712, for example, discloses a document processing apparatus having push-type copier function, to which a camera for automatically take a picture of an operator of the document processing apparatus. While the operator is operating the document processing apparatus for the creation of a document file, the camera automatically take a picture of the operator thereby to form image data. The image data can be sent to a desired destination with the document file. A receiver of the image data and the document file uses a document control program that indicates the image file as a thumbnail. The receiver can identify the sender before opening the document file.
When displaying a list of documents or a document, a document control system such as an electronic bulletin board, a video conference system, and a workflow system generally indicates not only the title of the document, the text (body) of the document, and the data and time of the document, but also the name or any identification of the writer of the document, for example.
When the receiver would like to contact the sender, the receiver may be able to make a phone call, send an e-mail, originate video conference, or visit the sender. However, the receiver may not know which way is the best to contact the sender.
The conventional document processing apparatus described above allows the receiver to view the image of the sender before opening the document file, which results in preventing the receiver from opening a questionable document file that may be infected with computer virus.
However, in the case of the conventional document processing apparatus described above, the receiver can view the past image of the sender acquired at the time the document file was created, not the current image of the sender. Thus, the receiver cannot know the current status of the sender, and cannot determine which the best way to contact the sender is, that is, making a phone call, sending an e-mail, or originating a video conference.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The preferred embodiments of the present invention are described in detail below.
FIG. 1 is a block diagram showing the configuration of a document viewing system 1 according to an embodiment. The document viewing system 1 includes a network such as a local area network that is operated by an organization such as a company and a local government. Server computers that function as a document management system 3, a current image distribution system 4, and a communication system are connected to the network 2. The server computers operate as a data control system according to an embodiment. Multiple personal computers (PC) 6 are connected to the network 2 as client computers.
FIG. 2 is a block diagram showing the hardware structure of the server computer 3, 4, or 5, and the client computer 6 included in the document viewing system 1. As shown in FIG. 2, these computers include CPU 12 that centrally control other components and memory 13 including various ROM and RAM connected to a bus 14.
The following components are further connected to the bus 14 via interface: a magnetic storage unit 15 such as a hard disk drive, an input unit 16 such as a keyboard and a mouse, a display unit 17, a recording medium reading unit 19 that reads programs and data stored in a recording medium 18 such as an optical disk, and a communication control unit 20 that interfaces communication with the network 2.
The client computer PC 6 has an imaging unit 21 that acquires moving or still image connected to the bus 14. This imaging unit 21 is installed such that it can acquire the image (at least a waist shot) of a user (writer) operating the PC 6 from the display unit side. In the case in which the communication system 5 supports video conference between the client computers PC 6, the client computer PC 6 includes a microphone 22 connected to the bus 14. This microphone 22 is used to collect the voice of the user (writer) of the client computer PC 6.
An example of the recording medium 18 may include an optical disk such as a CD and a DVD, a magneto-optical disk, and a flexible disk. The recording medium reading unit 19 may be an optical disk drive, a magneto-optical disk drive, and a flexible disk drive corresponding to the type of the recording medium 18.
Each of the server computers and the client computers reads a computer program 23 stored in the recording medium 18, and installs the read computer program 23 in the magnetic storage unit 15 for realizing the specific function of each computer. The computer program 23 may be downloaded through a network such as the Internet, and installed in the magnetic storage unit 15. The installed computer program 23 allows each of the server computers and the client computers to perform predetermined steps to be described below. The computer program 23 may be executed on an operating system (OS). The computer program according to an embodiment of the present invention corresponds to the computer program 23 installed in the document management system 3.
The operation of the document viewing system 1 is described below.
FIG. 3 is a block diagram showing the function of the document viewing system 1 according to an embodiment. The document management system 3 controls a document database (DB) 31 built in the magnetic storage unit 15. A number of data items (document data, in this case) can be registered to the document database 31. In response to a request from a client PC 6, a document list display unit 32 presents the list of documents registered to the document database 31, and a document display unit 33 presents the contents of at least one of the documents registered to the document data base.
An example of the contents of the documents registered to the document database 31 includes the title of the document, the data and time of registration, the writer of the document as well as the text (body) of the documents. The identification information (writer ID) is also registered being related to each document to indicate who the writer of the document is.
The identification of the client PC 6 (device ID) and the writer ID of a user (writer) who uses the client PC 6 are registered to the current image distribution system 4 being related to each other. In response to receipt of a writer ID from the document list display unit 32 and/or the document display unit 33 of the document management system 3, the current image distribution system 4 identifies a device ID registered in connection with the writer ID. The current image distribution system 4 acquires the image data of a still picture or moving picture (current image) captured by the imaging unit 21 of the client PC 6 identified by the device ID, and transmits the image data to the document management system 3. As described above, the writer ID and the device ID can be used as identification of the imaging unit 21 provided to each client PC 6.
When presenting the contents of a document registered to the document database 31, the document display unit 33 acquires the writer ID of the document to be presented, and transmits the writer ID to the current image distribution system 4. The image distribution system 4 acquires the image data of the current image from the client PC 6 corresponding to the writer ID, and transmits the acquired image data to the document display unit 33. The document display unit 33 presents the current image with the contents of the registered document.
FIG. 4 illustrates an exemplary screen of the display unit 17 of the client PC 6. The screen shown in FIG. 4 includes the current image 105 as well as the title 101 of the document, the date 102 of the document, the writer 103 of the document, and the text (body) 104 of the document.
When the document list display unit 32 presents the list of documents registered to the document database 31 to a requesting client PC 6, the document list display unit 32 obtains the writer ID's of the documents to be listed, and transmits the writer ID's to the current image distribution system 4. The image distribution system 4 acquires the image data of the current image from each client PC 6, the device ID of which has been received, and transmits the acquired image data to the document list display unit 32. The document list display unit 32 presents the current image with the contents of each registered document included in the list.
FIG. 5 illustrates an exemplary screen displayed by the display unit 17 of the client PC 6 in this case. The screen shown in FIG. 5 includes the current image 105 of each registered document as well as the title 101, date 102 of registration, writer 103 of each document.
As described above, the document viewing system 1 allows the user (viewer) to view the current image 105 of the writer of the registered document or the list of registered documents when presenting the registered document or the list of registered documents. Therefore, if the user (viewer) wants to contact the writer, the user can determine how to appropriately contact the writer by checking the current image. For example, if the current image 105 shows that the writer is present at his/her desk, the user can select real time communication with the writer by telephone or video conference, for example. The user may visit the writer. If the current image 105 shows that the writer is not present at his/her desk, the user can send an e-mail message to the writer, for example. Alternatively, the user may wait for a while and check again the current image to determine that the writer has come back to his/her desk, and use telephone and/or video conference.
The user may contact the writer of the document through the communication system 5 after checking the current image of the writer of the document with the current image 105. The communication system 5 may be embodied as a video conference system, an e-mail system, and a chat system, for example. The user can contact the writer through video conference, e-mail, and/or chat.
In the case shown in FIG. 3, since the communication system 5 is a video conference system, the clients PC6 can communicate by video conference via the communication system 5. In this case, when the user clicks a button “video conference” 106 in the screen shown in FIG. 4 (see FIG. 6 for the case in which the list of registered documents is presented), the document display unit 33 transmits the writer ID of the registered document to the communication system (video conference system) 5. The writer ID is registered to the video conference system 5 being related to the device ID of the client PC 6. The communication system 5 establishes video conference between the client PC 6 having the device ID corresponding to the received writer ID and the client PC 6 of the user who has viewed the registered document.
FIG. 7 is a block diagram showing the document viewing system 1 in the case in which the communication system 5 is an e-mail system. As shown in FIG. 7, the document management system 3 includes a user management database (DB) 34. The e-mail address of each user and the writer ID of the user are registered and related to each other. When the viewer of the registered document clicks a button “e-mail” 107 (see FIGS. 8 and 9), an e-mail creation screen (not shown) is opened on the client PC 6. The viewer of the registered document can write an e-mail message to the writer of the registered document using the e-mail creation screen. In response to receipt of the writer ID of the registered document, the document display unit 33 retrieves the e-mail address related to the writer ID. The e-mail message is sent to the retrieved e-mail address.
FIG. 10 is a block diagram showing the document viewing system 1 in the case in which the communication system 5 is the chat system. When the viewer of the registered document clicks a button “chat” 108 in the screen displayed on the client PC 6 (see FIGS. 11 and 12), the document display unit 33 activates the chat system 5. The viewer of the registered document can contact the writer of the registered document through chat (or instant message).
As shown in a block diagram of FIG. 13, the document management system 3 may not include the communication system 5, but include a document registration unit 35 that allows the viewer of the registered document to create a return document as a response to the registered document. The viewer can create the return document by clicking a button “return” 109 shown in the screen of the client PC 6. The document registration unit 35 acquires the document ID of the registered document viewed by the viewer from the document display unit 33. The document registration unit 35 registers the return document to the document database 31, the return document being related to the registered document viewed by the viewer. Specifically, the registered document and the return document to the registered document may be viewed using the client PC 6 in the similar manner as a document management system known as an electronic bulletin board.
As shown in the block diagram of FIG. 16, multiple types of communication system 5 and the document registration unit 35 may be provided at the same time. That is, the viewer of the registered document may contact the writer of the registered document through video conference, e-mail, and/or chat using the multiple communication systems 5 that are the video conference system, the e-mail system, and/or the chat system described above. The viewer of the registered document can register the return document to the document database 31 as described above. In this case, all buttons 106-109 are displayed on the screen of the client PC 6 as shown in FIG. 17. A command selection unit 36 provided in the document management system 3 selectively activates one of the multiple communication systems 5 and the document registration unit 35 in dependence on the button 106-109 selected by the viewer of the registered document.
In summary, if an imaging unit is provided to the client PC of each user of the document viewing system according to an embodiment, and enables image data of each user to be acquired, the document viewing system allows a user (viewer) who views a document written by another user (writer) to easily determine which (telephone, video conference, e-mail, or visiting, for example) the most appropriate way to contact the writer is by checking the image data of the writer acquired by the imaging unit.
The document viewing system allows the viewer to understand the current status of the writer through the viewing process of the data and feel familiar with the writer.
The preferred embodiments of the present invention are described above. The present invention is not limited to these embodiments, but variations and modifications may be made without departing from the scope of the present invention.
