Description

  The present invention relates to a system for transmitting information between a plurality of information communication terminals using a communication service function such as IM (Instant Message), for example, and in particular, each information communication terminal stores presence information indicating a user's state with each other. The present invention relates to an information communication terminal and a presence information sharing control program that are used in a system that is shared and selectively transmits information using a communication network according to the presence information.

  In recent years, applications that use communication networks are not limited to public landline telephone networks, but various access network environments such as wired LANs (Local Area Networks), wireless LANs (Local Area Networks), and public wireless data networks, indoors and outdoors Use in various places is assumed. In order to cope with such a wide variety of usage states, it is important for users to share information regarding their own state and convenience with each other.

  Therefore, in a communication application that transmits and receives information between a plurality of user terminals using a communication network, such as IM (Instant Message), information on the communication application and communication network used by the communication partner is displayed. There is an increasing use form in which the situation of a communication partner is known by sharing and information is transmitted / received to / from the communication partner in accordance with the shared information. In order to cope with such a usage pattern, a presence information sharing technique for sharing presence information including a user status and a communication application being used between user terminals has also been proposed (for example, Non-Patent Document 1). See).

  However, the conventional presence information sharing technology recognizes an input operation by a user such as a login operation for a communication service by a user and a selection operation of a communication network by a terminal keyboard, and the recognition result of the input operation is used as presence information. What is shared is mainstream. For this reason, other than simple information such as whether the user terminal is online or offline, the user must manually input the information by operating the keyboard of the communication terminal.

  In a variety of communication network connection forms and surrounding situations, when a user communicates while moving, information on the user's situation varies widely and frequently. For example, when a mobile communication network such as a mobile phone network or a wireless LAN is used, the location and connection destination network frequently change as the user moves. In addition, presence information representing the user's state frequently changes in accordance with changes in the state in which the user is placed, for example, the position, time zone, function and operating state of the communication terminal, mood, session status, and the like.

Under such circumstances, in the conventional technology in which the user himself / herself manually inputs characters and performs selection operation to update presence information,
(1) Since the user feels complicated in the input operation, the convenience of sharing presence information is impaired.
(2) A user's manual input operation cannot respond to a frequently changing surrounding situation, and the shared presence information does not reflect the actual situation, and communication according to the user's condition and convenience becomes difficult.
There is a problem.

  The present invention has been made paying attention to the above circumstances, and its purpose is to enable the presence information to be updated quickly and accurately according to changes in the surrounding situation, thereby reducing the burden of input operations by the user. It is an object to provide an information communication terminal and a presence information sharing control program that can reduce presence and improve the reliability of shared presence information, and can also share presence information that respects the privacy of users.

In order to achieve the above object, the information communication terminal or presence information sharing control program according to the present invention stores in advance when a detection element relating to the state of the user or the information communication terminal used by the user is captured . Based on information indicating a list of information communication terminals that share presence information and privacy requirements, only detection elements that the user has permitted to disclose are selectively captured for each communication partner . Then, it is determined whether or not a change of a predetermined amount or more has occurred in the movement amount or position of the user or the information communication terminal based on the captured detection element. A state element indicating whether or not the user or the information communication terminal is moving is generated, new presence information is generated based on the generated state element, and each time the new presence information is generated In addition, the generated new presence information is transmitted to the information communication terminal of the sharing partner.
Further, when generating the state element, first, it is determined whether or not a detection element indicating the movement amount has been acquired, and when the detection element indicating the movement amount can be acquired, the detection element of the movement amount has a predetermined amount or more. It is determined whether or not a change has occurred. When a change of a predetermined amount or more occurs in the movement amount detection element, a state element indicating that the user or the information communication terminal is moving is generated. On the other hand, if the detection element indicating the movement amount cannot be acquired, it is determined whether the detection element indicating the position has been acquired. If the detection element indicating the position can be acquired, the detection element at the position is determined. It is determined whether the user or the information communication terminal is outdoors or indoors. When it is determined that the user or the information communication terminal is outdoors, a state element indicating that the user or the information communication terminal is moving is generated. In addition, when a change of a predetermined amount or more does not occur in the detection element of the movement amount and when it is determined that the user or the information communication terminal is indoors, the user or the information communication terminal is not moving. A state element is generated.

Therefore, according to the present invention, the detection element related to the movement amount or position of the user or the information communication terminal used by the user is automatically captured from the sensor, and the user or the information is detected based on the captured detection element. A new state indicating whether or not the communication terminal is moving is recognized and reflected in the presence information. This eliminates the need for the user to manually input information corresponding to the detection element, thereby reducing the burden on the user and improving convenience. In addition, since presence information is automatically updated depending on whether the user is moving or not , the contents of the presence information can always be kept up-to-date, and using this presence information is always optimal. Network access is possible.

Furthermore, according to the above invention, among the various state elements of the user or the information communication terminal, only the state element that the user has permitted to disclose for each communication partner is reflected in the presence information. Therefore, it is possible to edit various contexts related to the user's situation into an information form that reflects personal circumstances while protecting privacy, and share this as presence information with others.
Furthermore, only the detection element that the user has permitted to disclose for each communication partner is selectively fetched from the sensor, and the state element indicating whether the user or the information communication terminal is moving based on the fetched detection element , And generating new presence information based on the generated information element, it is possible to reduce the processing amount of the detection element acquisition process and the condition determination process from the sensor, As a result, it is possible to shorten the time required to generate the presence information and extend the battery life by reducing the power consumption of the user terminal.

Further, the present invention selectively selects operation input information corresponding to privacy requirements set in advance corresponding to the user from among a plurality of operation input information related to the state of the user or the information communication terminal used by the user. The information processing apparatus further includes a capturing unit, and generates a state element indicating a movement amount or position of the user or the information communication terminal based on the captured operation input information and the detection element captured from the sensor. .

Therefore, according to the present invention , it becomes possible for the user to manually input information that cannot be detected by the sensor as needed, and presence information reflecting the manually input information is generated. For this reason, the contents of the presence information can be made more fulfilling in which the user's context is widely reflected.

  As the detection element to be captured, the detection element regarding the movement state, the detection element regarding the position, the detection element regarding the physical condition or the operation state, and the detection element regarding the state of the surrounding environment of the user or the information communication terminal used by the user Can be given. Thereby, it is possible to selectively reflect various detection elements relating to the state of the user or the terminal in the presence information.

  Examples of the operation input information to be captured include information indicating the current state or mood of the user, and information indicating the user's action schedule. This makes it possible to selectively reflect the current state or mood of the user and the action schedule in the presence information.

  In short, in the present invention, a detection element relating to the state of the user or the information communication terminal used by the user is captured, and a state element representing the state of the user or the information communication terminal is generated based on the captured detection element. The presence information is generated based on the generated state element. In addition, when generating the presence information, the privacy requirements of the user are taken into consideration.

  Therefore, according to the present invention, presence information can be updated promptly and accurately according to changes in surrounding conditions, thereby reducing the burden of input operations by the user and improving the reliability of the presence information shared. It is possible to provide an information communication terminal and a presence information sharing control program that enable sharing of presence information that is possible and respects the privacy of the user.

The communication device group 40 includes a plurality of communication devices 41 to 4k necessary for accessing the access networks NW1, NW2,.

  Presence information includes, for example, an IETF SIP for Presence draft specification, (1) a list of application names that can respond to calls, and how to call them (address information and numerical values that indicate the priority of calls) (2) Location information of the user (geographic information such as latitude / longitude and address) is included.

  In addition to the above elements, (1) a list of terminals owned by the user, (2) a list of network connection communication devices included in each terminal, (3) processing capability of the user terminal, (4 ) User terminal network connection status and available network resources, (5) User terminal position information (geographic information), (6) Information associated with the user's body movement (eg blood pressure, heart rate, walking) (State), (7) information around the user (eg ambient noise and brightness), (8) the state the user wants to express (eg “now busy”, “working”), (9) user's Current and near future schedules, (10) the status of the user (eg “meeting”, “going out”, “moving by train”, “working”), etc. Is considered.

  Each element (the user or the state element of the user terminal) constituting the presence information is connected to the operating information of the OS 10 in the user terminal TM1, the storage information of the memory 20, and the terminal in the presence information generation function 50. It can be generated by appropriately processing sensor information (detection elements) acquired from various sensors.

For example,
(1) The list of terminals held by the user includes information input by the user's setting operation and distance information between the user and the terminal using a short-range data communication device mounted on the user terminal. It can be generated by obtaining.
(2) A list of network connection communication devices 41 to 4k included in the user terminal TM1 can be obtained through the OS 10.
(3) The processing capability of the user terminal can also be acquired from the OS 10.

(10) For the situation in which the user is placed (for example, “meeting”, “going out”, “moving by train”, “working”), the user inputs characters directly or various sensors Can be generated based on the sensor information acquired from the above, or based on a schedule management application operating on the user terminal TM1.

  By the way, the constituent elements of the presence information to be shared do not necessarily include all the above elements from the viewpoint of user privacy protection. The presence information generation function 50 selects an element permitted to be disclosed by the user for each communication partner in accordance with a preset privacy logic and a list of communication partners (Buddy List), and presence information including only the selected element. Is generated.

  FIG. 2 is a functional configuration diagram for explaining the generation process of presence information that satisfies the privacy requirements in the presence information generation function 50. The presence information generation function 50 includes a sensor information reception interface 510, a plurality of condition determination script modules 521 to 52i, a privacy logic execution parent script 530, a privacy logic 540, an information disclosure partner list (Buddy List) 550, information Output script modules 561 and 562.

  Among them, the privacy logic 540 is information describing what information is output as presence information according to the state of the user, and is input and set in advance by the user. The information disclosure partner list (Buddy List) 550 is information indicating a list of communication partners sharing the presence information, and this is also input and set in advance by the user.

  The sensor information reception interface 510 receives sensor signals SS1 to SSj from various sensors S1 to Sj installed outside the terminal via a short-range data communication line such as a communication cable or Bluetooth (registered trademark), for example. Then, the received sensor signals SS1 to SSj are converted into sensor information SD1 to SDj having a predetermined data format, and the sensor information SD1 to SDj is accumulated.

  The condition determination script modules 521 to 52i determine whether or not a change of a predetermined amount or more has occurred in the state of the user or the user terminal TM1 based on the sensor information SD1 to SDj. When a change of a predetermined amount or more is detected, information for notifying the communication partner of the change is generated as one component of presence information.

For example, when determining whether or not the user is moving, the condition determination script modules 521 to 52i execute the following processing. FIG. 3 is a flowchart showing the processing procedure and processing contents.
That is, first, in step 3a, sensor information representing the amount of movement and sensor information representing the position information are read from a movement sensor such as a pedometer (registered trademark) and a position information sensor such as a GPS receiver, respectively. If sensor information representing the movement amount can be acquired from the movement sensor, the process proceeds from step 3b to step 3c, where it is determined whether or not the movement amount is equal to or greater than a predetermined amount. If the amount of movement is greater than or equal to the predetermined amount as a result of this determination, character information indicating “moving” is generated as a component to be included in the presence information in step 3d.

  On the other hand, when the sensor information indicating the movement amount cannot be acquired from the movement sensor, the process proceeds from step 3b to step 3e, where it is determined whether the position information can be acquired from the position information sensor. If the position information can be acquired, it is determined in step 3f based on the acquired position information whether the user is currently indoors. As a result of the determination, if it is determined that the user is outdoors, the process proceeds to step 3d to generate character information indicating “moving”.

On the other hand, if it is determined in step 3c that the amount of movement is less than the predetermined amount, or if it is determined in step 3f that the user is currently indoors, the process proceeds to step 3h, where “ The character information “not moving” is generated as a component to be included in the presence information.
If it is determined in step 3b that sensor information indicating the amount of movement cannot be acquired, and it is determined in step 3e that position information cannot be acquired, the process proceeds to step 3g to change the user's movement state. Does not generate character information to represent.

  The privacy logic execution parent script 530 selectively calls the condition determination script module corresponding to the sensor information specified by the privacy logic 540 from the condition determination script modules 521 to 52i, and authenticates the information according to the sensor information. Make a decision. Then, the information output script modules 561 and 562 are executed according to the determination result.

  The information output script modules 561 and 562 include only components satisfying the privacy requirements among the components generated by the condition determination script modules 521 to 52i based on the determination result by the privacy logic execution parent script 530. Presence information PD is generated. Then, the generated presence information PD is output to the presence information sharing function 60.

  The presence information sharing function 60 receives the generated new presence information PD from the information output script modules 561 and 562 each time new presence information PD is generated by the presence information generation function 50. Then, the new presence information PD is transmitted to the communication terminal of the sharing partner using an available communication application and communication device. At the same time, the presence information sharing function 60 receives presence information transmitted by the communication terminal of the sharing partner using the communication application and the communication device, and stores it in the memory 20.

  The presence information processing function 70 determines the status of the user who is the communication partner and the terminal in accordance with the presence information stored in the memory 20. Then, an optimum access network is selected for communication with the communication partner.

  As described above, in this embodiment, the user terminals TM1 to TMn are provided with the presence information generation function 50. In the presence information generation function 50, sensor information is acquired from the plurality of sensors S1 to Sj provided outside the terminal by the sensor information reception interface 510, and the condition determination script module 521 is based on the acquired sensor information. The state of the user or the terminal is determined by ~ 52k, and information representing the determination result is generated. Then, of the generated information, information specified by the privacy logic 540 set in advance is selected, presence information including only the selected information is generated, and the generated presence information is shared with the other party. Is sent to other communication terminals.

  Therefore, according to this embodiment, the detection information indicating the state of the user or the terminal is automatically captured from the sensors S1 to Sj, and a new user or information communication terminal is added based on the captured detection information. The situation is determined and reflected in the presence information. This eliminates the need for the user to manually input information representing his / her new situation, thereby reducing the burden on the user and improving convenience. In addition, since presence information is automatically updated according to changes in the user's situation, it becomes possible to keep the contents of the presence information up to date at all times. By using this presence information, an optimal access network is always available. Can be selected.

  Furthermore, only the components that satisfy the privacy requirements among the components generated by the condition determination script modules 521 to 52i are reflected in the presence information. That is, among various state elements representing the user's situation, state elements relating to the user's privacy are automatically excluded. For this reason, it becomes possible to share a user's context with others, protecting a user's privacy.

  The present invention is not limited to the above embodiment. For example, as a method for selecting an element that satisfies the privacy requirement, all sensor information is acquired from the sensors S1 to Sj, and the elements are generated by the condition determination script modules 521 to 52i based on the sensor information. The element specified by the privacy logic 540 is selected from a plurality of elements and reflected in the presence information, and only the sensor information specified by the privacy logic 540 is acquired and the acquired sensor information is used as the basis. It is conceivable to create an element in and reflect it in the presence information. By adopting the latter method, it is possible to reduce the processing amount of sensor information acquisition processing and condition determination processing, thereby shortening the time required to generate presence information and reducing the power consumption of the user terminal. Battery life can be extended.

  In the above embodiment, the sensor information is captured from the sensors S1 to Sj, and the presence information is generated based on the captured sensor information. However, the context information input by the user from the operation input unit is captured, Presence information may be generated based on the captured context information and the sensor information. For example, the user inputs his / her schedule information, information indicating the current situation, and the like using the key input unit. The user terminal captures the schedule information input by the key input means, information indicating the current situation, and the like, and generates presence information based on the captured context information and the sensor information.

  In this way, the user can manually input information that cannot be detected by the sensor as necessary, and presence information reflecting the manually input information is generated. For this reason, the contents of the presence information can be made more fulfilling in which the user's context is widely reflected.

  In addition to the key input means, the operation input means includes a writing input means and a voice input means, and further, for example, context information created by a user input on another personal computer, such as a magnetic disk or a memory card. Means for using the storage medium or taking in via a signal cable compatible with USB or the like is also included.

  In addition, when there are a plurality of the operation input means, the operation input means for inputting information designated by the privacy logic 540 is selected, and the input information is obtained only from the selected operation input means. The input information may be reflected in the presence information. In this way, it is possible to reduce the amount of input information acquisition processing and condition determination processing, thereby reducing the time required to generate presence information, reducing the power consumption of the user terminal, and reducing the battery life. Can be extended.

  In addition, the types and number of access networks, the types of information communication terminals, the types and number of state elements that make up presence information, the processing procedure and contents of presence information, and the generated presence information are shared with other terminals The processing procedure and contents for making it possible, the type of context information of the user to be detected, etc. can be variously modified and implemented without departing from the gist of the present invention.

  In short, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
