Description

  The present invention relates to an information processing system and a terminal, and more particularly, to an information processing system and a terminal that can control multimedia functions of terminals belonging to different categories.

  In recent years, with the progress of networking and the improvement of technology of electronic devices, many proposals regarding electronic classrooms and schools in which student terminals and teacher terminals are connected have been made.

There are three types of such proposals as described below.
1) Each student is in the same classroom and takes classes at the same time (non-remote / group type)
2) Each student is physically separated from the teacher or school, but takes classes at the same time (remote / group type),
3) Each student is physically separated from the teacher or school and takes classes individually (remote / individual).

  In particular, in the case of non-remote / group type, the student terminal is a replacement for a conventional textbook or notebook in that the student terminal is brought to school by the student and used in class in the same way as a conventional textbook or notebook. is there.

  As an example of such non-remote / group-type technology, Patent Document 1 shows a form in which an instructor terminal and a student terminal having a multimedia function are connected to each other via a LAN. Patent Document 2 discloses a form in which a user's system notebook is connected to each other wirelessly.

  On the other hand, in the case of the non-remote / group type, students generally have a name tag in the classroom. For example, Patent Documents 3 and 4 disclose a security system using a name tag. Patent Document 3 discloses a technology in which a transponder that transmits an individual ID is embedded in a name tag, a badge, or the like of a specific user, and the user can recognize the ID just by approaching the computer device, and only the user can operate the computer device. Is disclosed. Patent Document 4 discloses a technology that includes a wireless tag that stores identification data of a person on a name tag, and that the security terminal updates the wireless tag to determine whether to allow or reject the activation of the special function. .

  In the education support system disclosed in Patent Document 1, it is possible to use a multi-window environment by handling multimedia information and controlling the window of the student terminal from the instructor terminal side. However, if the activation of the multimedia function is entrusted to each student, the student may be distracted and not concentrate on the class, or the niece may play the voice without permission and hinder the progress of the class. In addition, since the teacher (teacher) terminal and the student (student) terminal are configured differently, the demand for the teacher terminal is the same as the demand for the student terminal even if such a system is introduced. Since it is generally low, the teacher terminal is expensive.

Further, in the technologies disclosed in Patent Documents 3 and 4, the name tag simply automates authentication (login) and logout.

  Embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

<First Embodiment>
As shown in FIG. 1, the information processing system according to the first embodiment of the present invention includes terminals 101, 102, 103, and 104, an AV amplifier 105, and a speaker 106 that are assumed to be used by teachers and students. The large screen monitor 107 and the communication line 108. In addition, although the number of terminals is four here, it is not restricted to this.

  Referring to FIG. 1, it is assumed that terminals 101, 102, 103, 104, AV amplifier 105, and large screen monitor 107 are connected by a communication line 108. Hereinafter, the communication line 108 is assumed to be wireless, but may be wired. However, wireless connection is preferable in terms of portability and a feeling closer to that of a paper book. The AV amplifier 105 amplifies the input signal and outputs it from the speaker 106.

  In the present embodiment, each teacher and student has terminals 101, 102, 103, and 104 in the kitchen one by one, and is used in the classroom in an energized state. Terminals 101-104 have the same structure.

  In the embodiment of the present invention, the term "student" is used for the side receiving the lesson regardless of the type of educational institution, and the term "teacher" is used for the side performing the class for the student regardless of the type of educational institution. Represented by

  In the following description, it is assumed that the terminal 101 is used by a teacher and the terminals 102, 103, and 104 are used by students. Here, although the number of terminals used by the teacher is one here, this represents only a typical use situation and may be two or more. This is because, in reality, there may be a plurality of terminals used by a teacher, such as when a student is instructed by a plurality of teachers.

  Hereinafter, among the terminals 101 to 104, a terminal used by a teacher may be expressed as a “teacher terminal” and a terminal used by a student may be expressed as a “student terminal”. The teacher terminal will be described as the terminal 101, and the student terminal will be simply described as the terminal 102.

  FIG. 2 shows the hardware configuration of the terminal 101 used by the teacher (hereinafter also referred to as “component”), and FIG. 3 shows the hardware configuration of the terminals 102, 103, and 104 used by the student. In the first embodiment of the present invention, the terminals 101 to 104 have the same structure. However, since there are cases where the teacher terminal and the student terminal will be described later separately, another code is assigned.

  Referring to FIG. 2, the teacher terminal 101 performs data communication via a CPU (Central Processing Unit) 201, a RAM (Random Access Memory) 202, and a communication line 108 that control the entire teacher terminal 101 and perform various arithmetic processes. Communication unit 203, input device 204, start switch 205, display 206, speaker 207, ROM (Read Only Memory) 208, authentication information memory 209, external storage device 210, terminal identification information memory 211, system state memory 212, system state backup Each piece of hardware including a memory 213 is connected by a data bus 214.

  Referring to FIG. 3, the student terminal 102 includes a CPU 301 that controls the entire student terminal 102 and various arithmetic processes, a RAM 302, a communication unit 303 that performs data communication via the communication line 108, an input device 304, and an activation switch. 305, display 306, speaker 307, ROM 308, authentication information memory 309, external storage device 310, terminal identification information memory 311, system state memory 312, system state backup memory 313, each of which is connected by a data bus 314. The

  Hereinafter, in the description of the configuration and operation of the terminals 101 to 104, the terminal 102 will be representatively described. Unless otherwise specified, the description regarding the terminal 102 also applies to the other terminals 101, 103, and 104.

  In this way, by making the teacher terminal and the student terminal have the same configuration, mass production becomes possible, and in particular, the production price of the teacher terminal can be reduced.

  Here, an example of an external view of the terminal 102 is shown in FIG. Here, a portable terminal having an A5 size display 306 is assumed, and all components are housed in a housing 502.

  Note that the present invention is not limited to the form shown in FIG. 4 and may be a form embedded in the desk 601 when used in a classroom as shown in FIG. Even in such a form, if the terminal 102 is structured to be removable from the desk 601, it can be used outside the classroom. In this example, by providing the handle 602 in the terminal 102, the terminal 102 can be easily carried, and the student terminal 102 can be easily attached to and removed from the desk 601. In addition, by providing the notch 603 in the desk 601 and allowing the user to insert a hand from there, the terminal 102 can be easily attached to or removed from the desk 601. In this case, as shown in FIG. 6, it is preferable that the student terminal 102 is configured so that there is no step with the desk 601 when the student terminal 102 is attached. In this way, the user can easily work on the desk 601.

  In this way, by using an electronic terminal that is easy to carry, it is possible to realize the same convenience as a paper textbook that has been popular in the past.

  In the form shown in FIG. 5, a power cable 604 is connected to the desk 601, and the terminal 102 is fed from there. Therefore, a large-capacity battery for classroom operation is not necessary, and the terminal 102 can be made lighter. In addition, the communication line 108 reaches the desk 601. As described above, if the communication line 108 is wired, terminals can be connected by wired communication, and high-speed communication can be performed more reliably than wireless communication.

  In this case, the communication unit 303 may perform either wired communication or wireless communication. For example, the terminal 102 can receive high speed and certainty of wired communication when necessary while performing portability by performing wired communication when embedded in the desk 601 and wireless communication otherwise. Can be realized.

  Next, referring again to FIG. 3, the hardware configuration of the terminal 102 will be specifically described.

  The communication unit 303 can perform wireless data communication via the communication line 108. In addition, the input device 304 receives an instruction input from the user, for example, by selecting a part of the display 306 with a finger. Note that the input device 304 may be a stand-alone keyboard connected to the terminal 102 or a device capable of inputting text by voice.

  The activation switch 305 is a switch having two states, ON and OFF. When the activation switch 305 is switched from the OFF state to the ON state by a user operation, the terminal 102 is activated.

  The authentication information memory 309 is a non-volatile memory that cannot be rewritten by a general user. There may be a privileged “administrator” user who can rewrite the authentication information memory 309, or the authentication information memory 309 may be created by the manufacturer as ordered. Hereinafter, “user” refers to the above-mentioned “general user” who cannot rewrite the authentication information memory 309.

  The authentication information memory 309 is a non-volatile memory that cannot be removed by the user. An example of the contents of the authentication information memory 309 is shown in FIG. User identification information 3701 corresponding to a legitimate user of the terminal 102, a password 3702, and user attribute information 3703 indicating whether the user is a student or a teacher are stored. Here, if the value of the user attribute information 3703 is “0”, the student is indicated, and if “1”, the teacher is indicated. In the example of FIG. 7, for example, the password 3702 of the user having the user identification information 3701 “MATSUMOTO” is “SHINANO”, and the value of the user attribute information 3703 is 0, so that this user is a student. I understand.

  Note that, as an example of the contents of the authentication information memory 309, a combination of user identification information and a password has been described here, but this is not restrictive. For example, a character string that is difficult to guess by a third party may serve as both user identification information and a password. Further, the contents of the authentication information memory 309 may be encrypted and stored in order to protect the system from malicious users.

  The terminal identification information memory 311 is a nonvolatile memory that cannot be rewritten by the user, and stores information for uniquely identifying the terminal. Here, for simplicity of explanation, it is assumed that numbers starting with 1 are assigned to the terminals 101, 102, 103, and 104 as 1, 2, 3, and 4 in order as terminal identification information. This may be expressed as the terminal numbers of the terminals 101 to 104 below. Of course, this is one example of the terminal identification information, and other numbers may be used, and the terminal identification information may not be a number. For example, a character string uniquely assigned to each terminal may be used.

  In the embodiment of the present invention, other well-known techniques are used for other components (such as a power supply) and operations not described.

  The external storage device 310 stores contents such as text, images, sounds, and moving images. The CPU 301 can read the content stored in the external storage device 310 and output it to the display 306 and the speaker 307. Note that it is not always necessary to play the same content on the teacher terminal and the student terminal. For example, the textbook content is played on the student terminal, and the textbook content containing the explanation for the teacher is played on the teacher terminal. Also good. In addition, a function may be provided in which a user writes a memo or the like in content being played back on the terminal 102.

  As a form of content, for example, it is assumed that the content is divided into pages with numbers, and the pages in the content are sequentially numbered (page numbers) starting from 0. Further, it is assumed that numbers (audio data numbers) starting from 0 are sequentially assigned to audio data in the content. Similarly, it is assumed that numbers (moving image data numbers) starting from 0 are sequentially attached to moving image data in content.

  Such a content configuration is intended for electronic books, but this is merely an example, and other configurations and contents may be used.

  The ROM 308 is divided into seven areas as shown in FIG. In each area, an initial program 901, a teacher terminal program 902, teacher terminal data 903, a student terminal program 904, student terminal data 905, a common program 906, and common data 907 are stored. As a result, as described later, the same terminal 102 can operate as both a teacher terminal and a student terminal.

  The initial program 901 is a program executed on the terminal 102 immediately after the start switch 205 is turned on. The teacher terminal program 902 is a program executed when operating as a teacher terminal. The teacher terminal data 903 is data used by the teacher terminal program 902 and is not used by the student terminal program 904 described later.

  The student terminal program 904 is a program executed when operating as a student terminal. The student terminal data 905 is data used by the student terminal program 904 and is not used by the teacher terminal program 902.

  The common program 906 includes a subroutine called from both the teacher terminal program 902 and the student terminal program 904. The common data 907 is data used by both the teacher terminal program 902 and the student terminal program 904.

  Next, the operation of the terminal 102 at the time of activation by turning on the activation switch 305 will be described with reference to the flowchart of FIG.

  The CPU 301 activates the initial program 901 (step S3601). In accordance with the operation of the initial program 901, user identification information and a password are input by the user from the input device 304 (step S3602). The CPU 301 performs authentication by comparing the input user identification information and password with the authentication information memory 309 (step S3603). If the authentication is successful (YES in step S3603), the CPU 301 further determines whether the user is a teacher or a student with reference to the user attribute information 3703 in the authentication information memory 309 (step S3604). .

  If it is determined in step S3604 that the user is a teacher (YES in step S3604), the CPU 301 executes the teacher terminal program 902 (step S3605). If it is determined in step S3604 that the user is a student (NO in step S3604), the CPU 301 executes the student terminal program 904 (step S3606).

  Further, a modified example of the operation of the terminal 102 at the time of activation will be described using the flowchart of FIG. In this modification, authentication as a teacher is requested, but if that fails, the terminal 102 always operates as a student terminal.

  The CPU 301 activates the initial program 901 (step S2001). In accordance with the operation of the initial program 901, user identification information and a password are input by the user from the input device 304 (step S2002). The CPU 301 compares the input user identification information and password with the authentication information memory 309, and the user password corresponding to the input user identification information is correct, and the user attribute information 3703 in the authentication information memory 309 indicates that the user Is determined to have a value that means teacher (step S2003).

  If the user is determined as a teacher (YES in step S2003), the teacher terminal program 902 is executed (step S2004). In other cases (NO in step S2003), the student terminal program 904 is executed (step S2005).

  In addition, for example, it may be configured to select whether to start as a student terminal or a teacher terminal from a screen as shown in FIG. The screen shown in FIG. 11 is displayed on the display 306 when the activation switch 305 is activated. Here, if the teacher terminal area 2201 is touched, the corresponding character string “operates as a teacher terminal” is highlighted. If the YES button 2203 is touched in this state, it operates as a teacher terminal and this screen is closed. If the student terminal area 2202 is touched, “operate as a student terminal” is highlighted. If the YES button 2203 is touched in this state, the operation as the student terminal is selected. In such a configuration, authentication information is not used for authentication, and therefore the authentication information memory 309 can be omitted. However, since such a configuration makes it possible for anyone to use the teacher terminal, it is not necessarily suitable for any application.

  It should be noted that the category of whether the terminal 102 operates as a student terminal or a teacher terminal may be determined other than at the time of activation. In this case as well, an operation sequence for designating a category may be determined in advance.

  Thus, in the 1st Embodiment of this invention, the structure of a teacher terminal and a student terminal is made common. For this reason, it is not necessary to manufacture and store each terminal separately, and the manufacturing cost and distribution cost of the terminal 102 can be reduced.

  Further, as described above, the information processing system according to the first embodiment of this invention is an information processing system including one or a plurality of terminals, and each terminal is one of a plurality of categories or one of them. It belongs to the above. Which category each terminal belongs to is determined by a user operation.

  Next, referring again to FIG. 1, an image signal is input to the large screen monitor 107 wirelessly. The contents of the data represented by the image signal are the same as the contents input to the display 206 of the teacher terminal 101 and the display 306 of the student terminal 102. However, when the display 206 and the display 306 are vertically long screens and the large screen monitor 107 is horizontally long, the vertically long screen 402 is displayed on the display surface 401 of the large screen monitor as shown in FIG.

  The audio signal is input to the AV amplifier 105 wirelessly. The contents of the data represented by the audio signal are the same as those input to the speaker 207 of the teacher terminal 101 and the speaker 307 of the student terminal 102. The AV amplifier 105 amplifies the input audio signal and reproduces it with the speaker 106.

  Next, a process for controlling the operation of the student terminal 102 in which the teacher terminal 101 belongs to different categories will be described with reference to the flowchart of FIG.

  Referring to FIG. 13, a command for student terminal 102 or another student terminal is input from input device 204 of teacher terminal 101 (step S1401). In the first embodiment, as will be described later, the input command includes terminal identification information of the student terminal 102 or another student terminal as a parameter.

  The CPU 201 transmits the input command from the communication unit 203 to the student terminal 102 via the communication line 108 (step S1402). The student terminal 102 receives the command at the communication unit 303 (step S1403). Next, the student terminal 102 performs an operation according to the received command (step S1404).

  A series of processes from the above steps S1401 to S1404 are repeated each time the user of the teacher terminal 101 performs an operation corresponding to step S1401.

  The physical and logical data format itself used for communication of each command is not essential for understanding the present invention and will be omitted, but information including a command number and parameters is transmitted by command communication. The information to be transmitted may not be the command number itself, but may be information corresponding to the command number on a one-to-one basis (information that can uniquely determine the command number).

  The required parameters differ depending on the command, and are as follows. In the present embodiment, the expression “command number N” may indicate a command corresponding to the command number N.

The command number, [parameter], and [corresponding action] are shown below.
0, [Terminal Identification Information], “Allow audio playback”
1. [Terminal Identification Information], “Prohibit audio playback”
2. [Terminal identification information, audio data number, volume level], “Play specified audio data”
3. [Terminal Identification Information], “Allow video playback”
4. [Terminal Identification Information], “Prohibit video playback”
5. [Terminal identification information, video data number, volume level], “Play specified video data”
6. [Terminal identification information], “Allow audio signal output to AV amplifier 105”
7. [Terminal identification information], “Prohibit output of audio signal to AV amplifier 105”
8. [Terminal Identification Information], “Allow image signal output to large screen monitor 107”
9. [Terminal Identification Information], “Prohibit image signal output to large screen monitor 107”
10, [terminal identification information], “return to the state just before the previous command transmission”
11, [terminal identification information, page number], “display the contents of the Nth page”
12, [terminal identification information, volume level], “specify volume level of sound output from speaker 307”
13. [Terminal Identification Information], “Make students operate freely”
14, [terminal identification information], “Allow AV amplifier 105 to output output contents of speaker 307”
15. [Terminal identification information], “Let the large screen monitor 107 output the output contents of the display 306”
Any terminal identification information may be used as long as it can identify student terminals. Here, the terminal number described in the terminal identification information memory 311 of the terminal 102 is used. As already described, the terminal identification information stored in the terminal identification information memory 311 may not be a terminal number. Further, the terminal identification information included as a parameter in the command may not be in the same format as long as it can be mutually converted with the terminal identification information included in the terminal identification information memory 311. As a typical example, as described above, the terminal identification information memory 311 may be encrypted with terminal identification information.

  A virtual terminal number indicating all student terminals is defined as the terminal number in the command. Here, (-1) is used as such a special number. As a result, it is possible to specify individual terminals, and to specify all students' terminals in the classroom.

  The operation of the terminal 102 in step S1404 when the command is transmitted from the terminal 101 will be described based on the flowchart of FIG.

  The communication unit 303 receives the command (step S701). Note that the processing in step S701 is processing corresponding to step S1403 described above.

  The CPU 301 extracts terminal identification information from the received command (step S702). And it is judged whether a terminal number is (-1) (step S703), and if it is YES, it will progress to step S706. If NO, the CPU 301 determines whether the terminal identification information extracted from the command matches the contents of the terminal identification information memory 311 (step S704). If it does not match the contents of the terminal identification information memory 311 (NO in step S704), the current operation is continued (step S705) and this process is terminated. On the other hand, if it matches the contents of the terminal identification information memory 311 (YES in step S704), the process proceeds to step S706.

  However, the term “match” as used herein may mean that the content of the terminal identification information memory 311 matches as a result of predetermined conversion. That is, it is only necessary that the terminal targeted by each command received by the communication unit 303 can be determined.

  In step S706, the CPU 301 determines whether the command number is 10. If the command number is 10 (YES in step S706), the CPU 301 copies the contents of the system state backup memory 313 to the system state memory 312 (step S707), and proceeds to step S710. The configuration and operation of the system state memory 312 and the system state backup memory 313 will be described later.

  If the command number is 10 (NO in step S706), the CPU 301 copies the contents of the system state memory 312 to the system state backup memory 313 (step S708). Next, the CPU 301 changes the contents of the system state memory 312 and the system state backup memory 313 from the command and parameters included therein, the current contents of the system state memory 312 and the system state backup memory 313 (step S709).

  Next, the CPU 301 changes the system state in accordance with the updated contents of the system state memory 312 (step S710), and ends this process. As a result, the terminal 102 performs an operation according to the content of the command.

  Here, the configuration and operation of the system state memory 312 will be described with reference to the configuration diagram of FIG.

  The system state memory 312 includes an audio reproduction right register 801, a moving image reproduction right register 802, an audio signal output right register 803, an image signal output right register 804, a volume level register 805, a page number register 806, an audio data number register 807, moving image data. It consists of a number register 808, an audio signal output status register 809, an image signal output status register 810, and a data bus 811 connecting these components.

  It is assumed that the system state backup memory 313 has the same configuration. In step S707, the contents of each register in the system state backup memory 313 are copied to the corresponding register in the system state memory 312. Conversely, in step S708, the contents of each register in the system state memory 312 are copied to the corresponding register in the system state backup memory 313.

  The audio reproduction right register 801 takes a value of 0 or 1, and “0” indicates that audio reproduction is permitted and “1” indicates that it is prohibited.

  The moving image reproduction right register 802 takes a value of 0 or 1, and “0” indicates that moving image reproduction is permitted and “1” indicates that it is prohibited.

  The audio signal output right register 803 takes a value of 0 or 1, indicating that “0” is permitted to output an audio signal to the AV amplifier 105 and “1” is prohibited.

  The image signal output right register 804 takes a value of 0 or 1, indicating that “0” is permitted to output an image signal to the large screen monitor, and “1” is prohibited.

  The volume level register 805 takes a value from 0 to 15, for example, and indicates the volume level output from the speaker 307. “0” represents mute (silence), and the volume level increases as the number increases.

  The page number register 806 takes a value from 0 to 65535 and indicates the page number in the currently displayed content.

  The audio data number register 807 takes a value from 0 to 65535, and indicates the number of audio data in the currently displayed content.

  The moving image data number register 808 takes a value from 0 to 65535 and indicates the number of moving image data in the currently displayed content.

  The audio signal output status register 809 takes a value of 0 or 1, and “0” indicates that no audio signal is transmitted to the AV amplifier 105, and “1” indicates that an audio signal is transmitted to the AV amplifier 105. Indicates.

  The image signal output state register 810 takes a value of 0 or 1, and “0” indicates that no image signal is transmitted to the large screen monitor 107, and “1” transmits an audio signal to the large screen monitor 107. Indicates that

  Then, the operations of the CPU 301 and the system state memory 312 in step S709 are as follows.

  If the command number is 0, the CPU 301 sets 0 in the audio reproduction right register 801. If the command number is 1, the CPU 301 sets 1 in the audio reproduction right register 801.

  If the command number is 2, the CPU 301 sets 0 in the audio reproduction right register 801, and the audio data number included in the command in the audio data number register 807 is included in the command in the volume level register 805. Stores the volume level. This indicates a state where audio reproduction is permitted and audio data having a number indicated by the audio data number register 808 is being reproduced at a volume level indicated by the volume level register 805.

  If the command number is 3, the CPU 301 sets 0 in the moving image playback right register 802. If the command number is 4, the CPU 301 sets 1 in the moving image reproduction right register 802.

  If the command number is 5, the CPU 301 sets 0 in the moving image reproduction right register 802, the audio data number included in the command in the moving image data number register 808, and the volume level register 805 includes the command. Stores the volume level. This indicates that the moving image reproduction is permitted and the audio data having the number indicated by the moving image data number register 808 is being reproduced at the volume level indicated by the volume level register 805.

  If the command number is 6, the CPU 301 sets 0 in the audio signal output right register 803. If the command number is 7, the CPU 301 sets 1 in the audio signal output right register 803. If the command number is 8, the CPU 301 sets 0 in the image signal output right register 804. If the command number is 9, the CPU 301 sets 1 in the image signal output right register 804. If the command number is 10, step S709 is not reached.

  If the command number is 11, the CPU 301 sets the page number included in the command in the page number register 806. This indicates a state in which the contents of the Nth page are displayed. If the command number is 12, the CPU 301 sets the volume level included in the command in the volume level register 805.

  If the command number is 13, the CPU 301 stores 0 in the audio reproduction right register 801, 0 in the moving image reproduction right register 802, 0 in the audio signal output right register 803, and 0 in the image signal output right register. This means that the use of the device or function controlled by the four registers is left to the operation of the user of the terminal 102.

  If the command number is 14, the CPU 301 sets 1 in the audio signal output state register 809. If the command number is 15, the CPU 301 sets the image signal output state register 810 to 1.

  In step S710, the CPU 301 changes the state of the terminal 102 in accordance with the contents of the system state memory 312 set as described above. However, for command numbers 0, 3, 6, 8, and 13, the command processing ends when the value is set in the system state memory 312 in step S709, so the processing in step S710 is NOP (no operation). To do. This is because the content of the command permits some operation, and whether the actually permitted operation is performed depends on the subsequent operation of the user of the terminal 102. For command numbers 1, 4, 7, and 9, some operation is prohibited. In step S710, if the corresponding operation is performed, it is stopped.

  For command numbers 2, 5, 10, 11, 14, and 15, some operation is designated, and the CPU 301 changes the state of the terminal 102 so as to achieve such an operation. For example, if the command number is 15, transmitting an image signal to the large screen monitor 107 corresponds to this. Such an operation controls the operation of the terminal 102, particularly an operation that is considered to have a great influence on other users, and the use of a shared device from the terminal 101. In particular, as an operation that has a great influence on other users, it is considered as a typical example to control a multimedia function, for example, an audio output, but the operation control is not limited thereto. The AV amplifier 105 and the large screen monitor 107 are examples in which the use of individual terminals 102 of devices shared by the user is controlled.

  The system state memory 212 and the system state backup memory 213 in the terminal 101 are not particularly used in the first embodiment of the present invention. However, in order to make the hardware configurations of the terminal 101 and the terminal 102 the same. The system state memory 312 and the system state backup memory 313 have the same configuration. Of course, a configuration in which the terminal 102 changes the state of the terminal 101 by transmitting the command described here or another command (for example, a command indicating that the student has a question) to the terminal 101 is also conceivable. In this case, the system state memory 212 is used. Further, the system state backup memory 213 is also used to realize a command for returning the terminal 101 to the previous state, similar to the command number 10 described above.

  An outline of such an operation is as follows. The CPU 201 analyzes the command transmitted from the terminal 102 to the terminal 101, changes the system state memory 212 and the system state backup memory 213, and adjusts to the new state of the system state memory 212. Thus, the CPU 201 changes the state of the terminal 101. Such an operation can be performed by replacing the description of the operation of the terminal 102 and its components in steps S701 to S710 with the corresponding terminal 101 and its components.

  Here, a mobile phone terminal may be used as a terminal constituting the information processing system in the embodiment of the present invention. This is because today's general mobile phone terminals have functions and configurations similar to those of the information terminal shown in FIG. 3, for example, so that the above-described operation can be performed in the same manner using a mobile phone terminal. Because. Further, such an example has a preferable property that the function of the communication unit 303 is originally provided in the apparatus for the original purpose of the device. Of course, the communication unit 303 other than the communication means provided in the mobile phone terminal may be held and exchanged with the teacher terminal and the like.

  In this case, functions such as outgoing call, telephone call, incoming call, ringtone reproduction, speech, software execution, camera shooting, etc. can be considered as control targets in addition to voice output and video playback. For example, during a class, the teacher terminal performs controls to prohibit or permit functions such as playing ringtones on mobile phone terminals, receiving or speaking, executing software such as games that can be played on the terminal, and camera shooting. It is possible.

  Further, as will be described later in the third embodiment of the present invention, the command input itself may be performed from other than the teacher terminal. In this case, the mobile phone terminal can also be controlled from command input means other than the teacher terminal.

  As described above, the terminals in the communication system according to the first embodiment of the present invention belong to different categories depending on the user's operation even if they are the same terminal. In addition, the terminal can perform different operations or possible states depending on the category to which the terminal belongs. More specifically, it can be said that each terminal has different authority depending on the category to which the terminal belongs.

  As an example in which the authority of the terminal differs depending on the category, in the embodiment of the present invention, as will be described later, the teacher terminal can control the function of the student terminal. In addition, devices that can be freely used vary depending on the category to which each terminal belongs. For example, whether or not the student terminal can use the AV amplifier 105 and the large screen monitor 107 is controlled by the teacher terminal, but the teacher terminal itself can freely use such a device. In this example, the teacher terminal 101 has a wider range of devices that can be used freely than the student terminal 102.

  In addition, you may provide the apparatus which a student terminal is never permitted use. For example, the AV amplifier 105 may be configured such that an audio signal can never be output from the student terminal, and the devices that can be used by the student terminal and the teacher terminal may be configured otherwise. In this case, the teacher terminal simply has a wider range of devices that can be used than the student terminal.

  In other words, in this example, the authority given to each terminal determines the functions that can be controlled or used, the devices that can be controlled or used, or the range of other terminals that can be controlled.

  Such a configuration in which the authority varies depending on the category can be said to be particularly suitable for use in a group having a clear instruction system such as a classroom or a company. In the above example, there are two categories of teacher terminals / student terminals. However, another terminal category such as a guard terminal used by parents or a staff terminal used by school staff other than teachers is provided or added. Also good. Also in this case, similarly to the above, by performing authentication corresponding to the category of each terminal, it is possible to operate one type of terminal as a terminal belonging to a plurality of categories.

  Such categories are intended for school use, and of course there may be other ways in other usage situations. For example, in the case of a company, it is conceivable that categories of terminals used by general employees and terminals used by managers are provided to increase the latter authority. In this case, in using the terminal used by the manager, the same method as the authentication as the teacher terminal described with reference to FIGS. 7 and 10 is used.

  Depending on the purpose, the authority of each category may be configured in a hierarchy, and the authority may be increased for higher categories. For example, it may be configured such that there are many items that can be controlled by terminals belonging to other categories, or there are many types of devices that can be used.

  In addition, it is not always desirable to configure authority in a hierarchical manner. For a certain device or function, a terminal belonging to a certain category has a large authority, but for another device or function, a terminal belonging to another category. It is also possible to configure such that has a large authority. For example, in the case of a company, this configuration is effective when devices or functions that are familiar with handling differ depending on individual departments.

  In the first embodiment, communication from the teacher terminal to the student terminal is mainly performed in order to mainly control the student terminal from the teacher terminal. Of course, communication from the student terminal to the teacher terminal is used. It is good also as performing. As an example of a main application that can be achieved by doing so, a student's answer is transmitted from the student terminal to the teacher terminal, and the teacher scores the student's answer.

  In addition, student terminals may communicate with each other via the communication unit 303. As main applications that can be achieved by doing so, for example, students exchange each other's answers and messages.

  Further, as another example of a command for controlling the student terminal from the teacher terminal, reproduction of content other than the currently specified content or content may be prohibited. For example, reproduction of mathematics textbooks during English classes is prohibited, or reproduction other than history textbooks and supplementary readers is prohibited during history classes.

  As described above, in the information processing system according to the first embodiment, a terminal belonging to at least one category can control functions of terminals belonging to at least one other category. Therefore, it is possible to replace paper textbooks by enabling control that prevents inappropriate use for group classes while providing functions unique to electronic terminals.

  The teacher terminal may have a general remote control function such as controlling the volume and sound quality of the AV amplifier 105 and controlling the image quality of the large screen monitor 107.

<Second Embodiment>
The configuration of the information processing system in the second embodiment of the present invention is the same as the configuration of the information processing system shown in the first embodiment. Therefore, description of the configuration will not be repeated. In the present embodiment, description will be made using the terminal 102 as a representative of the terminals 101 to 104. Further, description will be made assuming that the terminal 101 indicates a teacher terminal and the terminal 102 indicates a student terminal.

  In the second embodiment, the parameters of commands transmitted from the teacher terminal 101 to the student terminal 102 in the first embodiment are different. In the second embodiment, user identification information for identifying a user of the student terminals 102 to 104 is input as a parameter of a command generated from the teacher terminal 101 instead of specifying the terminal identification information of the student terminals 102 to 104. .

  Hereinafter, a different part from the 1st Embodiment of this invention is demonstrated.

  As shown in FIG. 16, the ROM 208 is divided into eight areas. Similar to the ROM 308 shown in FIG. 8, each area includes an initial program 901, a teacher terminal program 902, a teacher terminal data 903, a student terminal program 904, student terminal data 905, a common program 906, and common data. 907 is stored, and the conversion table 1101 is further stored in the second embodiment.

  A configuration example of the conversion table 1101 is shown in FIG. In Embodiment 2, the conversion table 1101 is a table in which user identification information 1102 and terminal identification information 1103 are associated with each other. The user identification information 1102 indicates user names of the terminals 101 to 104, and the terminal identification information 1103 indicates terminal numbers that are terminal identification information of the terminals 101 to 104. “ANY_USER” is a virtual user name indicating all users, and the corresponding terminal identification information (−1) indicates all student terminals. This is the same as (-1) being used as a virtual terminal number indicating all student terminals in the first embodiment of the invention.

  In the second embodiment of the present invention, the correspondence table is on the ROM 208 and cannot be dynamically updated in accordance with the usage status of the student terminals 102 to 104. Therefore, the user identification information 1102 corresponds to the assumed users of the terminals 101 to 104, and does not reflect whether such users are actually using the terminals 101 to 104. .

  If terminal identification information 1103 (terminal number) is uniquely obtained from user identification information 1102 (user name), different user identification information 1102 (user name) corresponds to the same terminal identification information 1103 (terminal number). Also good. This particularly increases the versatility of the conversion table 1101 when the conversion table 1101 as described here is realized by the ROM 208.

  Here, the user identification information 1102 is an uppercase alphabet, but it is of course possible to store it in kanji, hiragana, katakana or other language characters, or other information such as an attendance number. Note that the terminal numbers listed here are not the only examples of the terminal identification information 1103 as described above.

  Next, operations of the teacher terminal 101 and the student terminal 102 will be described with reference to the flowchart of FIG. The user of the terminal 101 inputs a command including the user identification information 1102 as a parameter from the input device 204 (step S1501). The system operation in step S1501 is almost the same as the system operation in step S1401 shown in FIG. 13, except that user identification information is used instead of terminal identification information as a parameter included in the command.

  The CPU 201 refers to the conversion table 1101 and converts user identification information 1102 included as a parameter in the command into terminal identification information 1103 (step S1502). Then, the CPU 201 transmits a command including the converted terminal identification information 1103 from the communication unit 203 to the terminal 102 (step S1503). The operation of the system in step S1503 and subsequent steps is the same as the operation in step S1402 and subsequent operations of the information processing system according to the first embodiment. This is because, in step S1502, the command has the same format as that used in the information processing system of the first form, including the terminal identification information as a parameter. The terminal 102 receives the command at the communication unit 303 (step S1504). Next, the terminal 102 performs an operation according to the received command (step S1505).

  So far, the application of the teacher terminal to the identification of the student terminal has been mainly described, but the same method may be used for the identification of the student terminal and the teacher terminal.

  In the second embodiment of the present invention, when there are a plurality of terminals and there are users associated with each of the terminals, the associated user is identified by the user instead of specifying the terminal by the terminal identification information. By designating with information, it is particularly easy to control terminals used by other users. Note that the user identification information can also be used to specify a terminal used by the user.

  In this way, the terminal identification information is generally difficult to see and memorize for each user, but the user identification information for specifying the user who uses the terminal is affected even if the terminal is replaced. There is a merit that it is not received. In addition, since the user's own information is easy to store and is supposed to be stored, other terminals can be easily controlled.

<Third Embodiment>
The configuration of the information processing system in the third embodiment of the present invention is the same as the configuration of the information processing system shown in the first embodiment and the second embodiment. Therefore, description of the configuration will not be repeated. In the present embodiment, description will be made using the terminal 102 as a representative of the terminals 101 to 104. Further, description will be made assuming that the terminal 101 indicates a teacher terminal and the terminal 102 indicates a student terminal.

  In the third embodiment, the conversion table to terminal identification information existing in the ROM 208 in the second embodiment is configured to be placed in the RAM 202. As a result, the conversion table can be configured to be rewritable.

  Hereinafter, the operation of the terminal 102 immediately after the terminal is activated by operating the activation switch 205 and the activation switch 305 will be described with reference to the flowchart of FIG.

  Referring to FIG. 19, the CPU 301 executes an initial program 901 (step S1601). In accordance with the operation of the initial program 901, user identification information and a password are input by the user from the input device 304 (step S1602). The CPU 301 performs authentication by comparing the input user identification information (user name) and password with the authentication information memory 309 (step S1603). If the authentication is successful (YES in step S1603), the teacher terminal program 902 is executed (step S1604), and the process ends.

  On the other hand, if the authentication fails (NO in step S1603), the CPU 301 sends the user identification information (user name) input in step S1602 to the teacher terminal 101 as a pair with the content of the terminal identification information memory 311 ( Step S1605). Next, the CPU 301 executes the student terminal program 904 (step S1606).

  The terminal 101 receives the user name and terminal identification information transmitted from the terminal 102 by the communication unit 203 (step S1607). Next, the CPU 201 adds the received pair of the user name and the terminal identification information to the conversion table 1101 on the RAM 202 (step S1608), and ends this process.

  Of course, every time a new user or terminal participates in the information processing system according to the third embodiment of this invention, the processing from step S1601 is repeated.

  The use of the conversion table 1101 is as described in the description of the second embodiment of the invention, particularly in steps S1501 to S1505.

  In addition, if an operation sequence of the terminal 102 corresponding to logoff is determined, the content added to the conversion table 1101 in step S1607 can be deleted when such an operation is performed.

  As described above, the third embodiment of the present invention is different from the second embodiment in that the conversion table 1101 is on the RAM 202 and can be dynamically updated according to the usage status of the student terminals 102 to 104. Therefore, the user identification information 1102 indicates that such a user is actually using the terminals 102 to 104.

  As described above, the correspondence between the terminal identification information and the user identification information is dynamically obtained, and based on the correspondence, the user identification information is converted into the terminal identification information. In addition to the merits described in the embodiment, that is, the merits of being able to control other terminals more easily, the students can freely lend and borrow terminals, etc., and can freely replace faulty terminals. It is done.

  Heretofore, description has been made assuming that the input device 204 of the terminal 101 is used as means for inputting each command. However, the command input device 2109 is independent from the teacher terminal 101 as means for inputting commands as shown in FIG. It doesn't matter.

<Fourth embodiment>
FIG. 21 shows the configuration of an information processing system according to the fourth embodiment of the present invention.

  Referring to FIG. 21, the information processing system according to the fourth embodiment includes terminals 101, 102, 103, and 104, AV amplifier 105, speaker 106, and large screen monitor 107 shown in FIG. Server 1209 is included. These components are connected by a communication line 108. Since the configuration other than the server 1209 is the same as that of the first to third embodiments, description of the operation and configuration of other components will not be repeated. In the present embodiment, description will be made using the terminal 102 as a representative of the terminals 101 to 104. Further, description will be made assuming that the terminal 101 indicates a teacher terminal and the terminal 102 indicates a student terminal.

  The fourth embodiment of the present invention is configured such that, in the third embodiment, the conversion table existing in the RAM 202 is placed on the shared server 1209 instead of the teacher terminal 101. Therefore, only differences from the third embodiment will be described below. Note that a basic configuration will be described as compared with Embodiment 1 as appropriate.

  As shown in FIG. 22, the server 1209 includes a CPU 1301, RAM 1302, ROM 1303, external storage device 1304, input device 1305, display 1306, communication unit 1307, and a data bus 1308 connecting them. A communication unit 1307 is connected to the communication line 108 and exchanges data. As the input device 1305, a keyboard and a mouse that are normally used are assumed here, but other configurations may be used.

  Hereinafter, operations of the terminal 102 and the server 1209 immediately after the terminal is activated by the ON operation of the activation switch 305 will be described with reference to the flowchart of FIG.

  Referring to FIG. 23, CPU 301 executes initial program 901 (step S1701). In accordance with the operation of the initial program 901, user identification information (user name) and a password are input by the user from the input device 304 (step S1702). The CPU 301 performs authentication by comparing the input user identification information (user name) and password with the authentication information memory 309 (step S1703). If the authentication is successful (YES in step S1703), the teacher terminal program 902 is executed (step S1704), and this process ends.

  On the other hand, if the authentication fails (NO in step S1703), the CPU 301 sends the user identification information (user name) input in step S1702 to the server 1209 as a pair with the contents of the terminal identification information memory 311 (step S1703). S1705). Next, the CPU 301 executes the student terminal program 904 (step S1706).

  The server 1209 receives the user identification information (user name) and the terminal identification information transmitted from the student terminal 102 by the communication unit 1307 (step S1707). Next, the CPU 1301 adds the received pair of user identification information (user name) and terminal identification information to the conversion table 1101 on the RAM 1302 (step S1708).

  Note that if an operation sequence of the terminal 102 that is to be logged off is determined, the contents added to the conversion table 1101 in step S1707 can be deleted when such an operation is performed.

  Next, a method of using the conversion table 1101 will be described with reference to the flowchart of FIG. The same steps as those in FIG. 18 of the second embodiment are denoted by the same step numbers.

  The user of the terminal 101 inputs a command including the user identification information 1102 as a parameter from the input device 204 (step S1501). The CPU 201 transmits a command including user identification information 1102 (step S3901). The server 1209 receives a command including the user identification information 1102 through the communication unit 1307 (step S3902).

  Next, the CPU 1301 of the server 1209 converts the user identification information 1102 into the terminal identification information 1103 with reference to the conversion table 1101 of the RAM 1302 (step S3903). Then, the server 1209 transmits a command including the terminal identification information 1103 from the communication unit 1307 to the terminal 102 (step S3904).

  Then, the terminal 102 receives a command including the terminal identification information 1103 at the communication unit 303 (step S1504). Next, the terminal 102 performs an operation according to the received command (step S1505).

  Thus, the fourth embodiment of the present invention is essentially the same in operation as the third embodiment except for the physical location of the conversion table 1101.

  In the above description, the conversion table 1101 has been described so as to be physically concentrated in one place. However, in a situation where each terminal is connected in a network, each of the terminals distributed in the terminals 102 to 104 is distributed. The terminals 102 to 104 may have a pair of terminal identification information of a terminal and user identification information corresponding to a user who is currently using each terminal. In this way, it is possible to operate by assuming that there is a table called the conversion table 1101 by collectively referring to data distributed on the network.

  The difference between the third embodiment and the fourth embodiment is simply the difference in where the conversion table 1101 is physically located. Further, the means for converting the user identification information into the terminal identification information is not limited to the table format such as the conversion table 1101, but may be any other format as long as the correspondence can be obtained. As described above, the means for converting the user identification information into the terminal identification information can be placed on the server 1209, the terminal 101, or the terminal 102 in a distributed form as long as it can be accessed. Good.

  Furthermore, for example, a means for inputting each command and a means for determining a terminal targeted by each command. Can be ignored wherever they are physically located. As will be seen later in the eighth embodiment of the invention, there is no particular problem if the name tag worn by the student operates as a conversion table, and such name tag is connected by a communication line.

  For example, although the means for inputting each command has been described so far as being included in the terminal 101, the command may be input from the input device 1305 of the server 1209.

  In addition, in the above description, the determination of the terminal targeted by each command has been performed by each terminal 102 to 104. For example, such a determination may be performed by the server 1209 or the like. In this case, each terminal 102 receives the result by the communication unit 303.

  Heretofore, the conversion table has been used as the identification information conversion means for converting the user identification information and the terminal identification information. However, the conversion table may be converted using the following method, for example. The user identification information is represented by a prime number, the terminal identification information is represented by another prime number, and the product is recorded in the RAM 1302 of the server 1209 in the form of an array. Here, it is assumed that a set of prime numbers used for terminal identification information and user identification information is determined so as not to overlap.

  The operation of the server 1209 as the identification information conversion means at this time will be described based on the flowchart of FIG. Hereinafter, an array of user identification information and terminal identification information is represented by P [i] (i = 0, 1,...).

  The CPU 1301 of the server 1209 initializes the array index i to 0 (step S3801). Next, it is checked whether P [i] is divisible by the input user identification information (step S3802). If it is divisible (YES in step S3802), P [i] is divided by the input user identification information and converted to terminal identification information (step S3803). Then, the converted terminal identification information is output (step S3804), and the process ends.

  On the other hand, if P [i] is not divisible by the input user identification information in step S3802 (NO in step S3802), the CPU 1301 increments the array index i (step S3805). The CPU 1301 determines whether or not the array index i matches the array length (N) (step S3806).

  If the array index i matches N in step S3806 (YES in step S3806), a value of (−1) representing an error is substituted as terminal identification information (step S3807). This is because i indicates that none of P [i] matches. In a normal state, as long as the correspondence between each terminal identification information and the user identification information is unique, there is only one i for which P [i] is divisible by the input user identification information. Note that it always exists. Therefore, since i may not match any of P [i], a problem such as a change in the contents of the RAM 1302 by a malicious user, which will be described later, can be considered. I decided to assign it to the information. Of course, the value (−1) is an example, and other values may be used as long as they can be distinguished from normal terminal identification information. Further, it may be sufficient if the error end can be transmitted to another component by means other than the value of the terminal identification information.

  As a merit of such a form, by taking two prime numbers sufficiently large, it is very difficult to know the other without knowing at least one of the terminal identification information and the user identification information from the product, so the RAM 1302 Even if a malicious user can read the contents of the above, it may be difficult to misuse such as changing the correspondence between the terminal identification information and the identification information. In this example, as described above, even if the value of the RAM 1302 is changed, if it is not a product of prime numbers, an error occurs at the time of conversion to terminal identification information.

<Fifth embodiment>
The configuration of the information processing system in the fifth embodiment of the present invention is the same as the configuration of the information processing system shown in the first to third embodiments. Therefore, description of the configuration will not be repeated. In the present embodiment, description will be made using the terminal 102 as a representative of the terminals 101 to 104. Further, description will be made assuming that the terminal 101 indicates a teacher terminal and the terminal 102 indicates a student terminal.

  In the fifth embodiment, the conversion table 1101 is referred to when the student terminal 102 receives a command. Hereinafter, differences from the second embodiment of the invention will be described.

  Hereinafter, the operations of the teacher terminal 101 and the student terminal 102 will be described with reference to the flowchart of FIG. The same operations as those shown in FIG. 18 are denoted by the same step numbers.

  The user of the teacher terminal 101 inputs a command including user identification information from the input device 204 (step S1501). The CPU 201 transmits a command including the input user identification information from the communication unit 203 to the student terminal 102 (step S1802). The student terminal 102 receives a command including user identification information at the communication unit 303 (step S1803). Next, the student terminal 102 performs an operation according to the received command (step S1804). As can be seen from the above description, conversion of user identification information included as a parameter in the command into terminal identification information is not performed until step 1803 is reached.

  The operation of the student terminal 102 in step S1804 will be described based on the flowchart of FIG.

  The communication unit 303 receives the command (step S1901). Note that the process of step S1901 is a process corresponding to step S1803.

  The CPU 301 extracts user identification information from the received command (step S1902). The CPU 301 converts the user identification information extracted in step S1902 into terminal identification information using the conversion table 1101 (step S1903).

  The CPU 301 determines whether or not the terminal identification information obtained in step S1903 is (−1) (step S1904). If the terminal identification information is (−1) (YES in step S1904), the process proceeds to step S1907.

  On the other hand, if the terminal identification information is not (−1) (NO in step S1904), the CPU 301 compares the terminal identification information extracted from the command with the contents of the terminal identification information memory 311 (step S1905). If they do not match (NO in step S1905), the current operation is continued (step S1906) and the process ends.

  In addition, since the terminal identification information (−1) is included in the conversion table 1101 as corresponding to the user identification information “ANY_USER”, the terminal identification information (−1) can also appear in step S1904. Be careful.

  In step S1907, the CPU 301 determines whether the command number is 10. If the command number is 10 (YES in step S1907), the CPU 301 copies the contents of the system state backup memory 313 to the system state memory 312 (step S1908), and proceeds to step S1911.

  If the command number is not 10 (NO in step S1907), the CPU 301 copies the contents of the system state memory 312 to the system state backup memory 313 (step S1909).

  Next, the CPU 301 changes the contents of the system state memory 312 and the system state backup memory 313 from the current contents of the command and parameters included therein, the system state memory 312 and the system state backup memory 313 (step S1910). The process proceeds to step S1911.

  In step S 1911, the CPU 301 changes the system state in accordance with the updated contents of the system state memory 312. This process is completed.

  If the fact that the user identification information is included in the command received by the communication unit 303 is used, the following configuration is also possible. That is, if the terminal 102 itself holds user identification information corresponding to the user currently in use, the command is compared with the user identification information included in the received command, so that the command targets itself. Therefore, the conversion table 1101 can be omitted.

  However, in such a configuration, if there are two terminals having the same user identification information because the same user uses a plurality of terminals, it becomes impossible to distinguish and control the two terminals. . On the other hand, if there is the conversion table 1101, even in such a case, for example, in the conversion table 1101, a warning that the terminal identification information cannot be uniquely obtained from the user identification information is transmitted from the student terminal 102 to the teacher terminal 101. You may do it. Also, only in such a case, each terminal identification information is displayed on the teacher terminal 101, and the user is made to input again which one to select, or a warning sound is output from the speaker 307 of each terminal having the same user identification information. It is more preferable in that an operation such as generation is possible.

  Note that the conversion table 1101 may be placed physically away from the student terminal 102, such as a server, as in the fourth embodiment. Thus, where the conversion table 1101 physically exists is not important in the operation of the information processing system according to the fifth embodiment.

<Sixth Embodiment>
FIG. 28 shows the configuration of the information processing system according to the sixth embodiment of the present invention. The information processing system according to the sixth embodiment includes terminals 101, 102, 103, 104, AV amplifier 105, speaker 106, large screen monitor 107, name tags 2308, 2309, 2310, and space attribute information. Transmitters 2311 and 2312 are provided. These components are connected by a communication line 108.

  The operations of the constituent elements of the sixth embodiment of the invention are the same as those of the first to third embodiments except for the name tags 2308, 2309, and 2310, and the space attribute information transmitters 2311 and 2312. The description of the operation and configuration of the components will not be repeated. In the present embodiment, description will be made using the terminal 102 as a representative of the terminals 101 to 104. Further, description will be made assuming that the terminal 101 indicates a teacher terminal and the terminal 102 indicates a student terminal.

  In the sixth embodiment, when the student terminal 102 is used, name tags 2308 to 2310 for identifying the student are used for controlling and using the student terminal 102. That is, as will be described in detail later, the terminal 102 is automatically logged in using personal information in the name tags 2308 to 2310. In this embodiment, “login” includes permission to use a terminal.

  The name tags 2308, 2309, and 2310 are assumed to be carried by the user of the student terminals 102, 103, and 104 at a rate of one per user. In the sixth embodiment, the student terminals 102, 103, 104 and the name tags 2308, 2309, 2310 are described as three, but other numbers may be used. Also, the number of space attribute information transmitters 2311 and 2312 is two here, but other numbers may be used.

  In the following, “personal information” includes name, grade, title, etc. displayed on a traditional name tag.

  The space attribute information transmitters 2311 and 2312 transmit space attribute information indicating the place where the space attribute information transmitters 2311 and 2312 are installed. Hereinafter, the configurations of the spatial attribute information transmitter 2311 and the spatial attribute information transmitter 2312 are the same except for the content of the spatial attribute information to be transmitted. Therefore, the description regarding the spatial attribute information transmitter 2311 is the spatial attribute information unless otherwise specified. The transmitter 2312 is also applicable.

  An example of the space attribute information transmitted by the space attribute information transmitter 2311 is shown in FIG. This is an example assuming use in a school. Hereinafter, unless otherwise specified, “class” is used in the meaning of “class” without grade information, for example, “Class B” of “Class B”.

  The space attribute information transmitted by the space attribute information transmitter 2311 includes class identification information 3001, grade identification information 3002, and school identification information 3003. However, the class identification information 3001 and the grade identification information 3002 are empty when the space attribute information transmitter 2311 is installed in a (physical) space that does not correspond to a specific class or grade. If there is a space that does not correspond to a specific class but corresponds to a specific grade (a space shared by each class of the same grade), a space attribute information transmitter 2311 installed in such a space In the space attribute information transmitted by, only the class identification information 3001 is empty.

  When the space attribute information transmitter 2311 is installed in a space that does not belong to any school (a space other than the school), the school identification information 3003 is also empty in addition to the two.

  In order to prevent “spoofing” and the like, the spatial attribute information transmitter 2311 may encrypt and transmit the spatial attribute information, and the name tag 2308 may decrypt it after receiving it.

  Next, a configuration example of the name tag 2308 is shown in FIG. The name tag 2308 includes a CPU 2401, a personal information memory 2402, a communication unit 2403, a display 2404, a display switch 2405, a RAM 2406, and a data bus 2407 for connecting those components. Each component of the name tag 2308 is connected to a communication line via the communication unit 2403. The display 2404 can perform full dot display. Note that in this embodiment, the RAM 2406 is not necessarily provided and may not be provided.

  The configuration of the name tag 2309 and the name tag 2310 and the operation of each component are the same as those of the name tag 2308 except for the contents of the personal information memory 2402. Therefore, unless otherwise specified, the description regarding the name tag 2308 also applies to the name tag 2309 and the name tag 2310.

  A display based on the contents of the personal information memory 2402 is performed on the display 2404. FIG. 31 is a diagram for explaining the configuration of the personal information memory 2402.

  FIG. 31A illustrates the types of data stored in the personal information memory 2402. Here is an example that assumes use in school. In the personal information memory 2402, first name 2801, last name 2802, first title 2803, second title 2804, class identification information 2805, grade identification information 2806, school identification information 2807, and name readings are hierarchical information of the individual user. 2810, last reading 2811, user identification information 2808, and password 2809 are stored.

  A specific example of data stored in the personal information memory 2402 is shown in FIG. For example, “○ 郎” is stored as the name 2801, “Δ River” as the surname 2802, “Animal Protection Committee” as the first title 2803, and “Nissao” as the second title 2804. Also, “Class B” as class identification information 2805, “1 year” as grade identification information 2806, “☆ Yamanaka school” as school identification information 2807, “TARO” as user identification information 2808, “RIVE” as password 2809, name “•• Lou” is stored as the reading 2810, and “••” is stored as the last reading 2811.

  Note that the example shown in FIG. 31 is schematic, and how the information shown here is actually stored in the personal information memory 2402 is not essential to the present invention. Don't go into details.

  FIG. 32 shows a display example on the display 2404 when the example of the personal information memory 2402 shown in FIG. 31 is used.

  FIG. 32A shows a first name 2801 and a last name 2802, in which “Δgawa ○ ro” is displayed. This is mainly intended to be used when the user wearing the name tag 2308 is in the classroom indicated by the class identification information 2805. That is, the attributes other than the first name 2801 and the last name 2802 are clearly well known to surrounding humans, and therefore have little meaning to display. Therefore, only the first name 2801 and the last name 2802 are displayed. As can be seen from a comparison with FIG. 32B later, FIG. 32A uses a small amount of information to display, and displays using a large font. By doing so, it can be made easier to see. Here, the fact that the display 2404 can perform full dot display is utilized. Note that such a display 2404 is not necessarily required to perform full dot display.

  FIG. 32B displays first name 2801, last name 2802, class identification information 2805, and school year identification information 2806. This is mainly intended to be used when the user wearing the name tag 2308 is outside the classroom indicated by the class identification information 2805 but is in the school 2807 facility such as the school building or school ground of the school 2807. Yes. In this case, the class to which the user belongs belongs to the user's last name and first name, and is not always well known to the people around him. It is what.

  FIG. 32C is an example of display outside the school to which the user who wears the name tag 2308 is mainly intended to use when the user is outside the facility indicated by the school identification information 2807. In this case, the information of the school to which the user belongs is important, and conversely, what grade and class the user belongs to is important for people who meet outside the school, at least in normal circumstances. Low. Also, displaying personal names and the like is not always desirable from the viewpoint of personal information protection. Therefore, only the school identification information 2807 is displayed, and “☆ Yamanaka school” is displayed. Also in this case, the visibility is improved by enlarging the font as in FIG.

  The user identification information 2808 and password 2809 are not used to display the name tag 2308, but their roles will be described later. The first title 2803 and the second title 2804 will also be described later.

  For example, the user's first name 2801 and last name 2802 may be displayed outside the facility indicated by the school identification information 2807, or vice versa.

  Further, an example of a personal information memory other than that shown in FIG. 31 may be used. For example, the first name 2801 and the last name 2802 may not be separated.

  The display switching as exemplified in FIGS. 32A, 32B, and 32C can be performed by the user using the display switch 2405. FIG. However, in order to make it more effective, in the sixth embodiment of the present invention, such display switching is automatically performed based on the space attribute information transmitted from the space attribute information transmitter 2311.

FIG. 33 is a flowchart showing the operation of the name tag 2308 configured as described above. Here, as shown in FIG. 32, three types of display for in-class use, in-school use, and out-of-school use are distinguished.
The CPU 2401 receives the space attribute information described above from the communication unit 2403 (step S2901).

  Next, the CPU 2401 determines whether or not the space attribute information has been successfully received (step S2902). If the space attribute information has not been successfully received (NO in step S2902), the CPU 2401 displays for off-campus use as shown in FIG. 32C (step S2903), and the process ends. In many cases, the failure to receive the spatial attribute information means that the spatial attribute information transmitter that is transmitting the spatial attribute information is not installed nearby, so there is a possibility of being outside the school. This is because it is considered high. Therefore, the display that assumes the most general group is performed.

  If reception is successful in step S2902 (YES in step S2902), CPU 2401 compares school identification information 3003 included in the received space attribute information with school identification information 2807 included in personal information memory 2402 ( Step S2904). If they do not match (NO in step S2904), the CPU 2401 displays for off-campus use as shown in FIG. 32C (step S2903) and ends. This is because the user wearing the name tag 2308 indicates that he / she is in a different school from which he / she belongs.

  If they match at step S2904 (YES at step S2904), CPU 2401 compares grade identification information 3002 included in the received spatial attribute information with grade identification information 2806 contained in personal information memory 2402 (step S2905). ). If they do not match (NO in step S2905), the CPU 2401 displays the in-school display as shown in FIG. 32B (step S2906) and ends.

  If they match at step S2905 (YES at step S2905), CPU 2401 compares class identification information 3001 included in the received space attribute information with class identification information 2805 included in personal information memory 2402 (step S2907). ). If they do not match (NO in step S2907), the CPU 2401 performs a school display as shown in FIG. 32B (step S2906) and ends.

  On the other hand, if the two match at step S2907 (YES at step S2907), the CPU 2401 displays the in-class display as shown in FIG. 32A (step S2908) and ends.

  If the concept of displaying personal attributes other than surnames and first names, such as titles, only when they are meaningful, control is possible using the same concept as last names and first names. For example, the first title 2803 and the second title 2804 indicating the members appointed in the class are meaningful to display when the person is in the classroom indicated by the class identification information 2805. Since it seems that there is no point in displaying it in a normal situation outside the school, it should be controlled in that way. FIG. 34 (a) shows a display example within a class on the assumption of the above. Of course, if the first title and the second title are meaningful outside the class and within the school, such display may be performed for the school. An example of such a display is shown in FIG.

  Here, “Nissho”, which is a temporary role that is difficult to display with a name tag in a normal sense, is also displayed. This is also one of the advantages of the name tag 2308 of the present invention over the name tag in the normal sense.

  Such a configuration is possible if, for example, the personal information memory 2402 is configured to be rewritable, and if a certain command is received from the communication unit 2403, the CPU 2401 can rewrite the personal information memory 2402.

  If the operation of the name tag 2308 is generally expressed, the personal information is displayed efficiently by using the following properties 1 to 5 of personal information, and unnecessary personal information is not displayed. By protecting the information and displaying only the information necessary for the surrounding people, it is possible to display personal information that is easier to see, such as displaying in larger characters.

1. There is a hierarchy of inclusion relationships among multiple groups to which an individual belongs,
2. Depending on the situation at an individual point in time, the group to which the person belongs should be known to the surrounding people or a natural assumption. Therefore, there is information that does not need to be displayed again,
3. For humans who do not belong to the same group as the person, information on which group the person belongs to below a certain level of the inclusive hierarchy is not necessary under normal circumstances.
4). For people who do not belong to the same group as the person, there are personal attributes that are not necessary under normal circumstances,
5. A group often has a corresponding physical space.

  For example, the example shown in FIG. 32 is based on the premise of an inclusive relationship of a class school year school school as a human group. In other words, the group called class indicated by the class identification information 2805 is in a lower hierarchy than the group called grade indicated by the grade identification information 2806, and the group called grade indicated by the grade identification information 2806 is a group called school indicated by the school identification information 2807. It is in a lower hierarchy.

  Therefore, it is well-known that the users wearing the name tag 2308 belong to the same class as the users who are taking classes in the same classroom as the users wearing the name tag 2308 and who are performing daily activities together. Therefore, it is not necessary to display the class to which the user belongs to such surrounding people. This is the reason why it is useful to perform the display as shown in FIG. That is, the properties described in 1 and 2 above are used. In FIG. 32B, the school identification information is not displayed.

  Further, as shown in FIG. 32 (c), the fact that only the school identification information is displayed without displaying the family name and the first name outside the school is based on the characteristics described in the above 3 and 4.

  In addition, the above-mentioned control is possible because there is a corresponding physical space, such as a classroom for a group, a school building, and a school building for a group of school members. This is because the group can be discriminated by. Thus, the property described in 5 is used.

  Expressing the above in more general terms, the name tag 2308 adapts to contents or forms that are of high interest, high importance, or easier to understand for the surrounding people depending on the situation of the user wearing it. That is, the personal information of the user is displayed.

  As another example of displaying more easily understandable contents, when the grade identification information received by the name tag 2308 indicates a lower grade, the name reading 2810 and the name reading 2811 in the personal information memory 2402 2801 and surname 2802 may be displayed instead. That is, in this case, it is displayed in hiragana. In the same way, it is possible to display in Roman letters, katakana, etc. if the configuration of the personal information memory 2402 is so configured.

  In addition, the name tag 2308 in the sixth embodiment of the present invention uses the above-mentioned general properties of personal information, so that it can be widely applied in addition to the use in schools as described above. Is possible. Here, an example is given in which a school student is assumed as a user, but the application range of the name tag for performing such display is not limited to this. If the personal information to be displayed differs depending on the user's situation, the name tag 2308 as described here can be applied.

  FIG. 35A shows an example of a personal information memory 2402 that is assumed to be used in a company, for example. In the personal information memory 2402, first name 3201, last name 3202, first title 3203, second title 3204, section identification information 3205, division identification information 3206, company identification information 3207, and user identification information, which are user hierarchy information, are stored. 3208 and a password 3209 are stored.

  The first title 3203 and the second title 3204 indicate job titles in the company. As a group to which humans belong, the premise is an inclusive relationship of section-division-company. Here, section corresponds to "section" and division corresponds to "department". In the present embodiment, the meaning and the number of levels in the hierarchy are not limited.

  FIG. 35B shows a specific example of the personal information memory 2402 assumed to be used in a company. For example, “Oro” is stored as the name 3201, “Δ River” as the surname 3202, “section manager” as the first title 3203, and “in-house beautification committee” as the second title 3204. The section identification information 3205 is “development first section”, the division identification information 3206 is “development department”, the company identification information 3207 is “☆ yama industry”, the user identification information 3208 is “TARO”, and the password 3209 is “ “RIVER” is stored.

  Hereinafter, it is assumed that the space attribute information transmitter 2311 is appropriately placed in a company facility such as each section or a common space. Also, exactly as described in the school example, the content of the space attribute information transmitted from the space attribute information transmitter 2311 can be compared with the content of the personal information memory 2402, and the CPU 2401 can be used by the user wearing the name tag 2308. It is assumed that the location of can be determined.

  FIG. 36 shows an example of the contents of the spatial attribute information transmitted from the spatial attribute information transmitter 2311 that is assumed to be used in the company. The spatial attribute information transmitted by the spatial attribute information transmitter 2311 includes section identification information 3401, division identification information 3402, and company identification information 3403.

  FIG. 37 is a diagram showing a display example on the display 2404 when the personal information memory 2402 described in FIG. 35 is used.

  FIG. 37A shows a display example when the user wearing the name tag 2308 is in the section to which the user belongs, and only the first name 3201, the last name 3202, the first title 3203, and the second title 3204 are displayed. FIG. 37B is a display example when the same user is in the division to which the user belongs, and in addition to the above, section identification information 3205 is displayed.

  FIG. 37 (c) is a display example when the same user is in the company outside the division to which the user belongs, and division identification information 3206 is displayed in addition to the above. FIG. 37D shows a display example when the same user is outside the company, and only the surname 3202 and the company identification information 3207 are displayed.

  FIG. 38 is a flowchart showing the operation of the name tag 2308 configured to perform the display as shown in FIG.

  The CPU 2401 receives the space attribute information described above from the communication unit 2403 (step S3501). Next, the CPU 2401 determines whether or not the space attribute information has been successfully received (step S3502). If the space attribute information has not been successfully received (NO in step S3502), the CPU 2401 displays for external use as shown in FIG. 37 (d) (step S3503), and the process ends. In many cases, the failure to receive the spatial attribute information means that the spatial attribute information transmitter that is transmitting the spatial attribute information is not installed nearby, so it may be outside the company. This is because it is considered high. Therefore, the display that assumes the most general group is performed.

  If the reception is successful in step S3502 (YES in step S3502), the CPU 2401 compares the company identification information 3403 included in the received space attribute information with the company identification information 3207 included in the personal information memory 2402 ( Step S3504). If they do not match (NO in step S3504), the CPU 2401 displays information for external use as shown in FIG. 37D (step S3503), and the process ends. This is because the user wearing the name tag 2308 is in a different company from the one to which he belongs.

  If they match at step S3504 (YES at step S3504), CPU 2401 compares division identification information 3402 included in the received space attribute information with division identification information 3206 included in personal information memory 2402 (step S3505). ). If they do not match (NO in step S3505), the CPU 2401 displays an in-house display as shown in FIG. 37C (step S3506), and the process ends.

  If they match at step S3505 (YES at step S3505), CPU 2401 compares section identification information 3401 included in the received space attribute information with section identification information 3205 included in personal information memory 2402 (step S3507). ). If they do not match (NO in step S3507), the CPU 2401 performs display for the division as shown in FIG. 37B (step S3508) and ends.

  On the other hand, if the two match in step S3507 (YES in step S3507), the CPU 2401 displays the section for use as shown in FIG. 37A (step S3509), and the process ends.

  Here, an example has been described so far in which the spatial attribute information is obtained by transmission of the spatial attribute information transmitter 2311. However, sufficient accuracy can be secured, and the output result and correspondence between the school, class, company, department, etc. If it is, it is conceivable to obtain spatial attribute information using GPS. In any case, it is only necessary to have a means for acquiring spatial attribute information that can be used to determine what display should be performed based on the contents of the personal information memory 2402.

  In the application example at school described above, for the lower grades, in the same way as displaying the first name kana 2810 and the last name kana 2811 instead of the first name 2801 and the last name 2802, the notation of characters in different languages May be stored in the personal information memory 2402 and the display may be switched depending on the office where the user is located. Such display switching is considered effective in, for example, a multinational company. In this case, for example, the name tag 2308 of the same Japanese user displays the first name and the last name in Roman letters in the US office and in Chinese letters in the Japanese office based on the acquired space attribute information. This is also possible by configuring the personal information memory 2402 of the name tag 2308 as such. At that time, the layout of the display may be slightly changed so that the names are displayed in the order of first name and last name in the US office, and in the order of first name and last name in the Japanese office.

  In the sixth embodiment, as described above, the terminal 102 is automatically logged in using the personal information on the name tag 2308. Here, how the name tag 2308 is used for authentication of the terminal 102 will be described.

  FIG. 39 is a flowchart showing authentication processing in the terminal 102. Hereinafter, the operation of the terminal 102 will be described with reference to FIG.

  The CPU 301 activates the initial program 901 (step S2601). The CPU 301 requests the name tag 2308 to transmit user identification information 2808 and password 2809 included in the personal information memory 2402 (step S2602).

  The CPU 301 receives the user identification information 2808 and the password 2809 transmitted from the communication unit 2403 by the communication unit 303 (step S2603).

  Next, the CPU 301 performs authentication by comparing the user identification information 2808 and the password received in step S2603 with the contents of the authentication information memory 309 (step S2604). If the authentication is successful (YES in step S2604), the student terminal program 904 is executed (step S2605). If authentication fails (NO in step S2604), the process ends.

  As described above, in the sixth embodiment, it is possible to automatically log in to the terminal 102 using the information included in the personal information memory 2402 of the name tag 2308. Thereby, the burden of a user's operation can be reduced.

  Here, the description has been made with the use at school in mind, but the present invention can be applied to authentication of a general terminal even if it is not a student terminal. This case is also realized by performing the same processing as in steps S2601 to S2605.

  In addition, although the configuration for authenticating the terminal by the pair of the user identification information and the password has been described here, of course, this is only an example, and the name tag 2308 transmits user authentication information as user authentication information transmission means. Other methods may be used as long as they function. For example, as another example, a character string that is very long and difficult to be guessed by a third party may also serve as user identification information and a password. Also in this case, since the input of such a character string is automatically performed, a character string that is difficult to input by hand can be used as the user authentication information.

  Further, not only automation of login by authentication but also automation of logout may be performed using the name tag 2308. For example, when the CPU 301 communicates between the communication unit 303 and the communication unit 2403 of the name tag 2308 at regular time intervals and the communication is not successful, the CPU 301 considers that the user has logged out. This is because if the communication is interrupted, it is considered that the user has moved away from the terminal. When the user logs out and uses the user again, authentication is performed again according to the procedure shown in steps S2601 to S2605. In this way, when a user leaves the terminal 102, it is possible to prevent an unauthorized user from using the terminal.

  Thus, by automatically performing login and logout, a wider age group can use the terminal. In addition, in a large group, it is difficult to grasp whether all users are surely logging out of the terminal. Therefore, management can be facilitated by automating logout.

  Further, the name tag used in the sixth embodiment can select and display personal information for display from a plurality of personal information based on the space attribute information and the user hierarchy information. Thereby, it is possible to display personal information according to the surrounding situation.

<Seventh embodiment>
The configuration of the information processing system in the seventh embodiment of the present invention is the same as the configuration of the information processing system shown in the sixth embodiment. Therefore, description of the configuration will not be repeated. Hereinafter, description will be made with reference to the drawings used in the sixth embodiment. In the present embodiment, description will be made using the terminal 102 as a representative of the terminals 101 to 104. Further, description will be made assuming that the terminal 101 indicates a teacher terminal and the terminal 102 indicates a student terminal. Further, description will be made using the name tag 2308 as a representative of the name tags 2308 to 2310.

  In the seventh embodiment, in addition to the display control in the sixth embodiment, the name tag 2308 performs control for switching display according to the contents of the personal information memory of other name tags.

  Referring to FIGS. 28 and 30, name tag 2308 is configured to be able to transmit the contents of personal information memory 2402 from communication unit 2403. The name tag 2308 switches display according to the contents received from the other name tags 2309 and 2310. Hereinafter, description will be made using a name tag 2309 as a representative of other name tags.

  As described in the sixth embodiment, the name tag 2308 performs display control based on the space attribute information transmitted from the space attribute information transmitter 2311. For example, the name tag 2308 receives personal information including hierarchical information from another name tag 2309. In other words, if another name tag 2309 is nearby, display control is further performed according to the contents.

  For example, assuming a usage example in a school, if the hierarchy information received by the name tag 2308 from another name tag 2309 is the same class identification information 2805 as the user, display for the class is performed. If the hierarchy information received from the other name tag 2309 is different from the grade identification information 2806, but is the same school identification information 2807, the display for school use is performed.

  In addition, each name tag may store a priority order for hierarchical information in advance, and select personal information for display according to the priority order. For example, the priority order is set for the grade identification information 2806, and the grade identification information 2806 received from the other name tag 2309 displays the lower grade more preferentially than the grade identification information 2806 of the name tag 2308.

  Even in the case of a multinational company or the like, the same control can be performed by changing the configuration of the personal information memory 2402 of the name tags 2308 to 2310. In this case, for example, when the hierarchical information transmitted from the name tag 2309 of the surrounding user indicates that the user is a foreigner, the last name, the first name, etc. are displayed in the notation of Roman characters or other appropriate foreign language characters. It is good.

<Eighth Embodiment>
The configuration of the information processing system in the eighth embodiment of the present invention is the same as the configuration of the information processing system shown in the sixth embodiment. Therefore, description of the configuration will not be repeated. Hereinafter, description will be made with reference to the drawings used in the sixth embodiment. In the present embodiment, description will be made using the terminal 102 as a representative of the terminals 101 to 104. Further, description will be made assuming that the terminal 101 indicates a teacher terminal and the terminal 102 indicates a student terminal. Further, description will be made using the name tag 2308 as a representative of the name tags 2308 to 2310.

  In the eighth embodiment of the present invention, the name tag 2308 described in the sixth embodiment also functions as a conversion table 1101 that converts user identification information 1102 into terminal identification information 1103. As described in the fourth embodiment, this is a form in which the conversion table 1101 is distributed. If a user of another terminal is designated, an operation for designating the terminal can be performed.

  As described in the fourth embodiment, as long as each component is connected by the communication line 108, the physical location of the conversion table 1101 is not a problem, and thus such an operation can be performed. Hereinafter, differences between the configuration and operation of the sixth embodiment of the invention will be briefly described.

  Referring to FIG. 39, after successful authentication in step S2604, the student terminal program 904 executed in step S2605 transmits the contents of the terminal identification information memory 311 to the name tag 2308. Further, it is assumed that the CPU 2401 stores the received contents of the terminal identification information memory 311 in the RAM 2406 in pairs with the user identification information 2808 included in the personal information memory 2402.

  With this configuration, where the name tags 2308, 2309, and 2310 already exist, the advantage of the fourth embodiment of the invention can be obtained without adding special hardware.

  Here, a method of using the conversion table 1101 will be described with reference to the flowchart of FIG. The same operations as those in FIG. 24 of the fourth embodiment are denoted by the same step numbers.

  The user of the terminal 101 inputs a command including the user identification information 1102 as a parameter from the input device 204 (step S1501). The CPU 201 transmits a command including user identification information 1102 (step S3901). Then, the name tag 2308 receives a command including the user identification information 1102 at the communication unit 2403 (step S4002).

  Next, the CPU 2401 of the name tag 2308 refers to the conversion table 1101 of the RAM 2406 and converts the user identification information 1102 into the terminal identification information 1103 (step S4003). Then, the name tag 2308 transmits a command including the terminal identification information 1103 from the communication unit 2403 to the terminal 102 (step S4004).

  Then, the terminal 102 receives a command including the terminal identification information 1103 at the communication unit 303 (step S1504). Next, the terminal 102 performs an operation according to the received command (step S1505).

  Further, the terminal identification information 1103 to which the user is currently logged in may be displayed on the display 2404 of the name tag 2308. In this embodiment, the contents of the terminal identification information memory 311 are stored in the RAM 2406, which is possible. By doing so, the user himself can easily know the terminal he is currently using. In addition, even if there is no automatic logout mechanism as described in the sixth embodiment of the invention, forgetting to log out or forgetting that you are already logged in, you can log in to another terminal. Can be prevented and contribute to efficient use of the system.

  This is because the name tag 2308 is often worn by the user or placed in a handy place. Therefore, if such information is displayed on the display 2404, the user and the people around him can now see the name tag 2308. This is because it is considered difficult to overlook that there is a terminal where the user is logged in. Such a configuration is considered to be particularly effective in the form in which automatic logout is not used as described in the sixth embodiment of the invention.

  Note that such a configuration in which the terminal identification information to which the user is currently logged in is displayed on the name tag 2308 does not require the name tag 2308 to function as identification information conversion means, and the terminal used by the user. The name tag 2308 only needs to hold the terminal identification information.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
