Patent Application
20200364019
The disclosures herein generally relate to a communication terminal, a management system, a communication system, and a display method.
Communication systems that provide a telephone call, a video conference, and the like via a communication network such as the Internet or a dedicated line have become prevalent in recent years due to a demand for reducing travel costs and time of parties. Such communication systems transmit/receive content data when communication is initiated between communication terminals. This makes communication between locations possible. Moreover, in order to enable smooth communication between locations, a method for sharing stroke data generated based on a handwriting operation as content data between the locations has been proposed.
For example, Patent Document 1 discloses a terminal apparatus in which location information such as an operator is stored in association with location identification information. When such a terminal apparatus receives handwritten data from another terminal apparatus, identification information is attached to the handwritten data and location information associated with the location identification information is obtained. This allows the received handwritten data to be displayed along with location information such as an operator.
However, in a case where communication is made with a communication partner whose name is not managed by a communication terminal, including for example, a first-time communication partner, the name of the communication partner cannot be displayed in association with stroke data when the stroke data is transmitted by the communication partner. Therefore, there is a problem with insufficient flexibility in displaying location information.
According to one embodiment, a communication terminal for communicative connection to at least one other communication terminal via a network includes a receiving part configured to receive stroke data transmitted from the other communication terminal, an obtaining part configured to obtain name information that is associated with a transmission source of the stroke data under management by a management system on the network, and a display control part configured to perform control that displays an image based on the stroke data and an image based on the obtained name information in association with each other.
In the following, embodiments of the present invention will be described with reference to the accompanying drawings.
The communication system 1 allows strokes in which a character, a figure, a symbol, and the like are drawn to be shared between the IWBs (20a, 20b, and 20c).
Moreover, the IWB 20, the relay apparatus 30, and the management system 50 are communicatively connected to one another via a communication network 2 such as the Internet, a mobile phone network, or a local area network (LAN). A single IWB 20 is placed at the locations (A, B, and C), respectively. By using the IWB 20, a video conference between locations can be performed. Also,
Next, a hardware configuration of the present embodiment will be described.
In an input apparatus 300, a signal transmitting apparatus is provided. When the nib of the input apparatus 300 comes into contact with the display surface 222, the signal transmitting apparatus transmits a writing detection signal (contact detection signal), which is a radio signal. When the writing detection signal transmitted by the input apparatus is received by the IWB 20, the display 220 displays characters, figures, and the like written at a coordinate position detected by the touch panel 224. The device storage part 250 stores various devices such as a main body of the IWB 20, for example. In addition, on the top side of the device storage part 250, a keyboard 230 is installed with which an input operation is performed.
Further, both the relay apparatus 30 and the management system 50 have the same external appearance as that of a generic server computer. Therefore, descriptions of the external appearance of the relay apparatus 30 and the management system 50 will be omitted.
Next, referring to
For example, the display 220 includes a liquid crystal display and an organic electroluminescence display for displaying images. Also, the IWB 20 is provided with a signal receiving apparatus 225 that receives a contact detection signal transmitted from the input apparatus 300 and outputs the contact detection signal to the touch panel 224. A touch panel driver, which is a control circuit of the touch panel 224, recognizes an input operation based on the contact detection signal transmitted from the input apparatus 300 and outputs stroke data corresponding to the input operation performed on the input apparatus 300. Once the input operation is recognized, the display 220 built in the IWB 20 superimposes and outputs images based on stroke data output by the touch panel driver or based on stroke data transmitted from another IWB 20 via the communication network 2.
Also, the IWB 20 includes a display I/F 217 for transmitting data output to the display 220 or transmitting data input from the touch panel 224 according to the control of the CPU 201, an external device connection I/F 218 for connecting various external devices to the IWB 20, an alarm lamp 219 for notifying a user of an abnormality of each function of the IWB 20, and a bus line 210 such as an address bus and a data bus for electrically connecting the above-described elements as illustrated in
Further, the IWB 20 may be provided with a hardware configuration that is not illustrated in FIG. 3, depending on the function. Moreover, a part of the hardware configuration illustrated in
The hardware configuration of the relay apparatus 30 is same as the hardware configuration of the management system 50, and thus a description thereof will be omitted.
Next, a functional configuration of the present embodiment will be described.
The IWB 20 of the present embodiment includes a transmitting/receiving unit 21, an operation input receiving unit 22, a display control unit 23, and a storage/reading unit 29. Any of the elements illustrated in
Next, each functional configuration of the IWB 20 will be described in detail.
The transmitting/receiving unit 21 is operated by an instruction from the CPU 201 and the network I/F 211. The transmitting/receiving unit 21 transmits/receives various types of data (or information) to/from a terminal, each apparatus, a system, or the like of the other communication partner via the communication network 2.
The operation input receiving unit 22 is operated by an instruction of the CPU 201, the touch panel 224, the power switch 209, and the keyboard 230. The operation input receiving unit 22 receives various types of inputs and various types of selections made by the user.

The relay apparatus 30 includes a transmitting/receiving unit 31 and a storage/reading unit 39. Any of the elements illustrated in
Next, each functional configuration of the relay apparatus 30 will be described in detail.
The transmitting/receiving unit 31 of the present embodiment is operated by an instruction from the CPU 501 and the network I/F 509. The transmitting/receiving unit 31 transmits/receives various types of data (or information) from/to a terminal, each apparatus, a system, or the like of the other communication partner via the communication network 2.

The management system 50 includes a transmitting/receiving unit 51, a session control unit 58, and a storage/reading unit 59. Any of the elements illustrated in
The storage unit 5000 is provided with a terminal management DB 5002 that includes a terminal management table. Table 1 is a conceptual diagram illustrating the terminal management table. In the terminal management table, a communication ID for identifying the IWB 20 of a communication destination is managed in association with a location name. Such a communication ID is not particularly limited and may be any information capable of identifying the IWB 20 of the communication destination. For example, communication IDs include information for identifying an IWB 20, an account name of a user of an IWB 20, and the like. In a case where the communication ID is an account name, the account name transmitted in response to a login request from an IWB 20 to the management system 50 and identification information of the IWB 20, from which the login is requested, may be managed in association with each other in the management system 50. In this way, the management system 50 can identify the IWB 20 by using the account name. Hereinafter, the communication IDs of the IWBs (20a, 20b, and 20c) will be described as being “02a, 02b, and 02c,” respectively. A location name is name information such as a name of a place or a name of a business place, with which the user can identify the other communication partner. Location names in the terminal management table can be updated by the management system 50 in response to a request from the IWB 20 based on the user's operation input.
Next, each functional configuration of the management system 50 will be described in detail.
The transmitting/receiving unit 51 of the present embodiment is operated by an instruction from the CPU 501 and the network I/F 509. The transmitting/receiving unit 51 transmits/receives various types of data (or information) to/from respective terminals, apparatuses, and systems via the communication network 2.
The session control unit 58 is operated by an instruction from the CPU 501. The session control unit 58 controls sessions for transmitting stroke data between IWBs 20. The above-described control includes control for establishing a session, control for causing an IWB 20 to participate in the established session, and control for disconnecting the session.
The storage/reading unit 59 is operated by an instruction from the CPU 501 and the HDD 505. Alternatively, the storage/reading unit 59 is operated by an instruction from the CPU 501. The storage/reading unit 59 performs processing for storing various types of data in the storage unit 5000, or performs processing for extracting the various types of data stored in the storage unit 5000.
Next, processing or operations of the IWB 20, the relay apparatus 30, and the management system 50 of the communication system 1 will be described.
The management system 50 establishes a session for transmitting stroke data via the relay apparatus 30 between the IWBs (20a, 20b, and 20c) according to the control of the session control unit 58. Hereinafter, the processing for transmitting stroke data between the IWBs 20 after the session is established will be described.
When a user of the IWB 20a brings the nib of the input apparatus 300 into contact with the input apparatus 300, the input apparatus 300 transmits a contact detection signal. When the contact detection signal is received by the signal receiving apparatus 225, the touch panel 224 serving as the operation input receiving unit 22 detects coordinates of the contact position and receives an operation input of a stroke (step S101).
The operation input receiving unit 22 that has received the operation input of the stroke generates stroke data indicating the stroke entered and also generates position information indicating the position of the stroke on the display surface 222 (step S102). The position information is not particularly limited, and may be coordinates of a starting point and coordinates of an ending point of the stroke. Alternatively, when the stroke is assumed to be an object, the position information may be coordinates of an upper edge, a lower edge, a right edge, a left edge, or a center point of the object.
The transmitting/receiving unit 21 transmits the stroke data and the position information generated in step S102 and also transmits the communication ID of the IWB 20a, which is of the same terminal, to the relay apparatus 30 (step S106). Because the session between the IWB 20a and the relay apparatus 30 has already been established, as long as the relay apparatus 30 can identify the transmission source of the stroke data without receiving the communication ID, the IWB 20a is not required to transmit the communication ID in step S106.
Further, the transmitting/receiving unit 21 of the IWB 20 of an embodiment may at any time transmit, to the relay apparatus 30, the stroke data generated before the operation input is completed in step S101, that is, while the operation input receiving unit 22 is receiving the operation input. In this case, the location name can be displayed on the display surface 222 at a point at which the user starts the input (starts the writing). This enhances usability.
The transmitting/receiving unit 21 of the IWB 20 of another embodiment may transmit the stroke data to the relay apparatus 30 after the operation input is completed in step S101. In this case, the position information about the completed stroke can be transmitted to the relay apparatus 30. Therefore, in the later processing, it is possible to avoid the entire display of the stroke from overlapping with the display of the location name on the display surface 222. This enhances legibility of the stroke or the location name.
The storage/reading unit 39 of the relay apparatus 30 generates an image management table in which the communication ID, the stroke data, and the position information received are associated with one another, and the storage/reading unit 39 of the relay apparatus 30 stores the image management table in the storage unit 3000 (step S108). Table 2 is a conceptual diagram illustrating the image management table generated by the relay apparatus 30. Also, the storage/reading unit 39 may record identification information (ID) of stroke data or a file name of stroke data in the stroke data field of the image management table, and may store the corresponding stroke data in any other storage space of the storage unit 3000.
The transmitting/receiving unit 31 of the relay apparatus 30 transmits the stroke data, the position information, and the communication ID transmitted from the IWB 20a, and requests the management system 50 for a location name of the IWB 20a (step S110).
In the management system 50 that has received the request for the location name, the storage/reading unit 59 searches the terminal management table (see Table 1) with the communication ID included in the request for the location name as a search key, and reads the location name corresponding to the communication ID (step S112).
The storage/reading unit 59 generates an image management table in which the communication ID, the stroke data, and the position information included in the request for the location name and the location name read in step S112 are associated with one another, and the storage/reading unit 59 stores the image management table in the storage unit 5000 (step S114). Table 3 is a conceptual diagram illustrating the image management table generated by the management system 50. The storage/reading unit 59 may record identification information (ID) of stroke data or a file name of stroke data in the stroke data field of the image management table, and may store the corresponding stroke data in any other storage space of the storage unit 5000.
As a response to the request for the location name, the transmitting/receiving unit 51 of the management system 50 transmits the communication ID of the IWB 20a and the location name read in step S112 to the relay apparatus 30, which is the source of the request (step S116).
In the relay apparatus 30 that has received the response, the transmitting/receiving unit 31 transmits the stroke data, the position information, and the communication ID transmitted from the IWB 20a and also the location name included in the response to the respective IWBs (20a, 20b, and 20c) participating in the session for transmitting the stroke data (steps S118-1, S118-2, and S118-3).
The respective display control units 23 of the IWBs (20a, 20b, and 20c) perform control that displays an image on the display 220 based on the stroke data, the position information, and the location name transmitted from the relay apparatus 30 (steps S120-1, S120-2, and S120-3). In this case, the display control unit 23 performs control that displays the stroke based on the stroke data at a position on the display surface 222 indicated by the position information. Also, the display control unit 23 performs control that displays the location name at a position on the display surface 222 corresponding to the above-described position information. For example, a position corresponding to position information includes a position of coordinate values that are calculated by adding or subtracting a given value to or from the coordinate values indicated by the position information or by 5 multiplying or dividing a given value by the coordinate values indicated by the position information. Accordingly, the location name is displayed near the stroke.
The processing performed when the input of the stroke is received by the IWB 20a has been described above. When the IWB 20b receives an input of a stroke, the same processing as that of the IWB 20a is performed, except that the description of the IWBs (20a, 20b, and 20c) is changed to the IWBs (20b, 20c, and 20a). Therefore, a detailed description thereof will be omitted. Similarly, when the IWB 20c receives an input of a stroke, the same processing as that of the IWB 20a is performed, except that the description of the IWBs (20a, 20b, and 20c) is changed to the IWBs (20c, 20a, and 20b). Therefore, a detailed description thereof will be omitted.
The processing of the above-described steps S101 through S120-1, S120-2, and S120-3 is performed each time a stroke is input into the IWBs (20a, 20b, and 20c). Such a series of processing allows the respective IWBs (20a, 20b, and 20c) to display a location name in association with the stroke input into the IWB 20.
Next, a first variation of the embodiment will be described.
By referring to
The transmitting/receiving unit 21 of the IWB 20a transmits, together with the stroke data and the position information generated in step S102, in addition to the communication ID of the terminal, the sign information generated in step S104A to the relay apparatus 30 (step S106A).
The transmitting/receiving unit 31 of the relay apparatus 30 transmits, to the management system 50, the stroke data, the position information, the communication ID, and the sign information transmitted from the IWB 20a, and requests the management system 50 for a location name (step S110A)
The session control unit 58 of the management system 50 determines whether the sign information included in the request for the location name matches sign information managed in the terminal management table (see Table 4) in association with the communication ID included in the request for the location name (step S115A). In this case, the session control unit 58 may calculate the matching rate of the two pieces of sign information. The session control unit 58 may determine that the two signs match when the matching rate exceeds a predetermined threshold, and may determine that the two signs do not match when the matching rate is equal to or less than the predetermined threshold. In step S115A, when the two signs are determined to match, the transmitting/receiving unit 51 transmits a response that includes the location name read in step S112 to the relay apparatus 30 (step S116). In step S115A, when the two signs are determined not to match, the transmitting/receiving unit 51 transmits a response that does not include the location name to the relay apparatus 30 (step S117A).
The transmitting/receiving unit 31 of the relay apparatus 30 transmits, to the IWBs (20a, 20b, and 20c), the stroke data, the position information, and the communication ID transmitted from the IWB 20a (steps S118A-1, S118A-2, and S118A-3). When the location name is included in the response transmitted from the management system 50, the transmitting/receiving unit 31 of the relay apparatus transmits the location name included in the response, together with the above-described stroke data, the position information, and the communication ID.
The respective display control units 23 of the IWBs (20a, 20b, and 20c) perform control that displays a stroke based on the stroke data and the position information transmitted from the relay apparatus 30 (steps S120A-1, S120A-2, and S120A-3). When the location name is transmitted together with the stroke data and the position information from the relay apparatus 30, the display control unit 23 performs control that displays the location name at a position corresponding to the position information. Accordingly, the location name associated with the stroke can be displayed only when an authorized user inputs a sign.
Next, a second variation of the embodiment will be described.
By referring to
The transmitting/receiving unit 21 of the IWB 20a transmits, together with the stroke data and the position information generated in step S102, in addition to the communication ID of the terminal, the sign information generated in step S104B to the relay apparatus 30 (step S106B).
The transmitting/receiving unit 31 of the relay apparatus 30 transmits, to the management system 50, the stroke data, the position information, the communication ID, and the sign information transmitted from the IWB 20a, and requests the management system 50 for a location name (step S110B)
The session control unit 58 of the 15 management system 50 determines whether the sign information included in the request for the location name matches sign information managed in the terminal management table in association with the communication ID included in the request for the location name (step S115B).
In step S115B, when the sign information transmitted via the relay apparatus 30 from the IWB 20a is determined to match the sign information managed in the terminal management table, the transmitting/receiving unit 51 transmits a response that includes the location name read in step S112 and also includes the sign information transmitted from the IWB 20a to the relay apparatus 30 (step S116B). In step S115B, when the two pieces of sign information are determined not to match, the transmitting/receiving unit 51 transmits a response that does not include either the location name or sign information to the relay apparatus 30 (step S117B).
The transmitting/receiving unit 31 of the relay apparatus 30 transmits, to the IWBs (20a, 20b, and 20c), the stroke data, the position information, and the communication ID transmitted from the IWB 20a (steps S118B-1, S118B-2, and S118B-3).
When the location name and sign information are included in the response transmitted from the management system 50, the transmitting/receiving unit 31 of the relay apparatus 30 transmits the location name and the sign information included in the response, together with the above-described stroke data, the position information, and the communication ID.
The respective display control units 23 of the IWBs (20a, 20b, and 20c) perform control that displays a stroke based on the stroke data and the position information transmitted from the relay apparatus 30 (steps S120B-1, S120B-2, and S120B-3). When the location name and the sign information are transmitted together with the stroke data and the position information from the relay apparatus 30, the display control unit 23 performs control that displays the location name and the sign information, namely a name, at a position corresponding to the position information.
Next, a third variation of the embodiment will be described.
By referring to
The storage unit 5000 of the management system 50 is provided with a user management DB 5011 that includes a user management table. Table 5 is a conceptual diagram illustrating the user management table. In the user management table, user IDs of IWB 20 users, address information of users, and user information that identifies users and that can be output from the IWB 20 are managed in association with one another. The user information includes text information such as user names or image information such as icons and thumbnails. In the user management table, names of text information files and image information files are also managed. The files identified by file names may be stored in a different storage space from the user management table of the storage unit 5000. Information managed in the user management table can be updated by the storage/reading unit 59 of the management system 50 in response to a request from the IWB 20 based on the user operation.
The transmitting/receiving unit 21 of the IWB 20a transmits, together with the stroke data and the position information, in addition to the communication ID of the terminal, address information indicating the address selected in step S105C to the relay apparatus 30 (step S106C).
The storage/reading unit 39 of the relay apparatus 30 generates an image management table in which the communication ID, the stroke data, the position information, and the address information transmitted from the IWB 20a are associated with one another, and stores the image management table in the storage unit 3000 (step S108C). Table 6 is a conceptual diagram illustrating the image management table generated in step S108C.
The transmitting/receiving unit 31 of the relay apparatus 30 transmits, to the management system 50, the stroke data, the position information, the communication ID, and the address information transmitted from the IWB 20a, and requests the management system 50 for a location name (step S110C)
In the management system 50 that has received the request for the location name, the storage/reading unit 59 searches the user management table (see Table 5) with the address information included in the request for the location name as a search key, and reads the user information corresponding to the search key (step S113C).
The storage/reading unit 59 generates an image management table in which the communication ID, the stroke data, the position information, and the address information included in the request for the location name, and the location name and the user information read in the respective steps (S112 and S113C) are associated with one another, and stores the image management table in the storage unit 5000 (step S114C). Table 7 is a conceptual diagram illustrating the image management table generated in step S114C.
As a response to the request for the location name, the transmitting/receiving unit 51 of the management system 50 transmits the communication ID of the IWB 20a and the location name and the user information read in the respective steps (S112 and S113C) to the relay apparatus 30, which is the source of the request (step S116C).
In the relay apparatus 30 that has received the response, the transmitting/receiving unit 31 transmits the stroke data, the position information, and the communication ID transmitted from the IWB 20a and also transmits the location name and the user information included in the response to the respective IWBs (20a, 20b, and 20c) participating in the session for transmitting the stroke data (steps S118C-1, S118C-2, and S118C-3).
The respective display control units 23 of the IWBs (20a, 20b, and 20c) perform control that displays a stroke based on the stroke data and the position information transmitted from the relay apparatus 30 (steps S120C-1, S120C-2, and S120C-3). Also, the respective display control units 23 perform control that displays the location name at a position on the display surface 222 indicated by the position information. Further, the respective display control units 23 perform control that displays an image based on the user information at a position on the display surface 222 corresponding to the position information. Accordingly, the image based on the location name and the user information is displayed near the stroke.
Next, main effects of the above-described embodiment will be described. An IWB 20 (an example of a communication terminal) is communicatively connected to at least one other IWB 20 via the communication network 2. The transmitting/receiving unit 21 (an example of a transmitting part) of the IWB 20 receives stroke data transmitted from the at least one other IWB 20. Also, the transmitting/receiving unit 21 (an example of an obtaining part) of the IWB 20 obtains a location name (an example of name information) that is associated with a communication ID of the other IWB 20, which is the transmission source of the stroke data, under management by the management system 50 on the communication network 2. The display control unit 23 (an example of a display control part) is configured to perform control that displays a stroke (an example of an image) based on the stroke data and the location name (an example of an image based on the name information) in association with each other. Accordingly, even without a name of a communication partner being managed by the IWB 20, it is possible to display the name in association with the stroke of the stroke data transmitted from the communication partner.
The operation input receiving unit 22 (an example of an operation input receiving part) of the IWB 20 receives an operation input by a user. The transmitting/receiving unit 21 (an example of a transmitting part) of the IWB 20 transmits the stroke data based on the above-described operation input to the at least one other IWB 20 via the relay apparatus 30. The transmitting/receiving unit 21 can transmit the stroke data while the operation input is being received. In this case, the location name can be displayed on the display surface 222 on the other communication partner side at a point at which the user starts the input (starts the writing). This enhances usability.
The transmitting/receiving unit 21 may transmit the stroke information after the operation input of the stroke is completed. In this case, the completed stroke can be transmitted to the relay apparatus 30. Therefore, in the later processing, it is possible to avoid the entire display of the stroke from overlapping with the display of the location name on the display surface 222. This enhances legibility of the stroke or the location name.
For respective communication IDs of IWBs 20, which are transmission sources of stroke data, the terminal management DB 5002 provided in the storage unit 5000 (an example of a managing part) of the management system 50 manages location names (an example of the name information) in association with the respective communication IDs. When the stroke data is transmitted to the above-described IWB 20 from another IWB 20, the storage/reading unit 59 (an example of an extracting part) reads (extracts) name information associated with the communication ID of the other IWB 20 from the terminal management DB 5002. The transmitting/receiving unit 51 (an example of a transmitting part) of the management system 50 transmits the extracted location name to the IWB 20. Accordingly, the above-described IWB 20 can obtain the location name of the transmission source of the stroke data.
For respective communication IDs of IWBs 20, which are transmission sources of stroke data, the terminal management DB 5002 manages sign information (first sign information) indicating signs of users in association with the respective communication IDs. When sign information (second sign information) is transmitted together with stroke data from another IWB 20, the session control unit 58 (an example of a determining part) determines whether the sign information transmitted from the other IWB 20 matches sign information managed in the terminal management DB 5002 in association with the communication ID of the other IWB 20.
When the session control unit 58 determines that the two pieces of sign information match, the transmitting/receiving unit 51 (an example of the transmitting part) of the management system 50 transmits the location name read by the storage/reading unit 59 to the IWB 20. Accordingly, the location name can be displayed on the IWB 20 when an authorized user inputs a stroke.
For respective pieces of address information of transmission sources of stroke data, the user management DB 5011 provided in the storage unit 5000 of the management system 50 manages user information (an example of user information) in association with the respective pieces of address information. When the address information is transmitted from another IWB 20, the storage/reading unit 59 of the management system 50 reads (extracts) user information associated with the address information transmitted from the other IWB 20 from the user management DB 5011. The transmitting/receiving unit 51 transmits the extracted user information to the IWB 20. Accordingly, in addition to the location name of the transmission source of the stroke data, the above-described IWB 20 can also obtain the user information of the user who is using the other IWB 20.
Each program for the IWB 20 and the 25 management system 50 may be recorded in a computer-readable recording medium (such as the recording medium 206) in an installable form or in an executable form, and may be distributed. Also, other examples of the above-described recording medium include Compact Disc-Recordable (CD-R), a digital versatile disc (DVD), and a Blu-ray disc. Further, the above-described recording medium or the HD 504 storing these programs may be provided as a program product domestically or abroad.
