However, the process can proceed recursively.

  Hereinafter, an embodiment in which a host-based information system of the present invention is applied to an information system having a plurality of clients capable of switching and displaying contents will be described with reference to the drawings.

<First Embodiment>
FIG. 1 is a diagram showing an external configuration of an information processing system 1 according to the first embodiment of the present invention. As shown in FIG. 1, the information processing system 1 includes a plurality of clients 10 having a light and thin form such as paper, and a host 20 having a pen-type instruction operation unit.

<Client configuration>
The client 10 includes an instruction connection unit 11, a connection control unit 12, a non-volatile storage unit 13, a processing unit 14, and a storage display 15, which are connected to each other via a bus 16 so as to communicate with each other.
The instruction connection unit 11 is an interface for inputting and outputting information and power between the client 10 and the host 20.

Specifically, the instruction connection unit 11 includes an antenna coil for inputting and outputting power and information corresponding to different instruction input contents, and is provided in an instruction connection unit 21 (described later) of the host 20. By being electromagnetically coupled to the antenna coil, it operates by receiving power from the host 20, receives information superimposed on the induction electromagnetic field, and modulates the induced return carrier wave with information to be transmitted. Thus, information is input to and output from the host 20.
Here, as information input / output between the client 10 and the host 20, the document data of the content to be displayed, the display data, the reaction map, and the tip of the operation instruction unit 28 (described later) of the host 20 are touched. The coordinates of the part, the processing state of various processes, etc. can be mentioned.

The reaction map shows the execution instructions associated with each instruction connection unit 11 and the document elements and dialogue elements (character strings, images, link information, execution instructions) displayed at the respective coordinates of the memory display 15. It is a map to show.
In this embodiment, according to this map, the instruction connection unit 11 at the top of FIG. 1 is associated with the execution instruction of the movement process to the next page, and the second instruction connection unit 11 extracts the character string. Processing execution instructions are associated with each other.

  The connection control unit 12 controls information and power input / output performed via the instruction connection unit 11. That is, the connection control unit 12 rectifies the input from the instruction connection unit 11 that is instructed and activated by the instruction connection unit 21 of the host 20, that is, the instruction connection unit 11 in which the induced power is generated, and extracts the operating power, After the activated instruction connection unit 11 is discriminated by a comparison circuit or the like, a client protocol based on predetermined serial data input / output with the host 20 is executed via the instruction connection unit 11. Thereby, the connection control unit 12 manages input / output to / from the non-volatile storage unit 13 or the processing unit 14. As will be described later, when the connection control unit 22 of the host 20 performs communication using a corresponding host protocol, the client 10 and the host 20 are in a connection state in which input / output can be performed transparently. At this time, the determination result of the activated instruction connection unit 11 can be referred to from the connected host 20.

The non-volatile storage unit 13 is configured by a non-volatile memory such as a flash memory. Information (content document data, display data, and reaction map) input from the host 20 via the instruction connection unit 11, The processing status of various processes to be performed is stored.
The processing unit 14 includes a display execution unit 17 and a reaction extraction unit 18.

  When the display data stored in the non-volatile storage unit 13 is updated, the display execution unit 17 directly controls the storage display 15 and causes the storage display 15 to display the updated display data. Specifically, the display execution unit 17 refers to the display data stored in the non-volatile storage unit 13 and drives the X driver and Y driver of the storage display 15 to thereby render the raster to be drawn. The figure is displayed on the memory display 15. For example, a passive matrix driving method, a TFT (Thin Film Transistor) method, or a D-TFD (Digital Thin Film Diode) method can be adopted as a method for driving the memory display 15.

  The reaction extraction unit 18 stores in the nonvolatile storage unit 13 when a determination result of the instruction connection unit 11 activated from the host 20 or an inquiry based on the coordinates of the portion touched by the tip of the operation instruction unit 28 is input. The execution instruction associated with the corresponding instruction connection unit 11 and the data of the document element and the interaction element displayed on the memory display 15 are extracted from the reaction map and the document data, and the extraction result is obtained. The data is output to the document processing unit 25 (described later) of the host 20 via the instruction connection units 11 and 21 and the connection control unit 22.

The memory-type display body 15 is configured by a display device having a high pixel density of A4 size, and displays raster data by displaying pixel data on predetermined pixels under the control of the display execution unit 17. As the memory display 15, for example, an electrophoretic display, a cholesteric liquid crystal display, a display using charged toner, a display using a twist ball, or an electrodeposition display can be employed.
In addition, a coordinate pattern such as an information graphic indicating coordinates on the surface is formed on the surface of the memory display 15 so as to be observable from the host 20, and the coordinates of the designated position are provided to the host 20 (described later).

<Host configuration>
Next, the host 20 includes an instruction connection unit 21, a connection control unit 22, a position detection unit 24, a document processing unit 25, an information service unit, and a power supply 26, which are configured to be communicable via a bus 27. Yes.
The instruction connection unit 21 is an interface for inputting and outputting information and power between the client 10 and the host 20, provided at the tip of the operation instruction unit 28. Specifically, the instruction connection unit 21 includes an antenna coil for inputting and outputting power and information, and is electromagnetically coupled to the antenna coil similarly provided in the instruction connection unit 11 of the client 10. As a result, information and power are input to and output from the client 10.

  The connection control unit 22 controls information and power input / output performed via the instruction connection unit 21. That is, the connection control unit 22 applies an alternating current including a control signal to the antenna coil based on the electric power from the power supply 26 to induce the antenna coil of the instruction connection unit 11 on the client 10 side, and the instruction connection unit 21. By controlling execution of a host protocol based on predetermined serial data input / output to / from the client 10 via the client, the input / output to / from the document processing unit 25 is managed.

When the tip of the operation instruction unit 28 touches the client 10, the infrared light receiving / emitting unit 23 irradiates the touched part with infrared light to receive reflected light, and outputs the light reception result to the position detection unit 24. As a method for detecting that the tip of the operation instruction unit 28 has touched the client 10, for example, a method of providing a switch at the tip of the operation instruction unit 28 or an electromagnetic method can be employed.
The position detection unit 24 includes an observation unit 29 and a calculation unit 30.
The observation unit 29 detects the coordinate pattern of the part touched by the operation instruction unit 28 based on the light reception result output from the infrared light receiving / emitting unit 23, and outputs the detection result to the calculation unit 30.
The calculation unit 30 calculates the coordinates indicated by the detection result (coordinate pattern) output from the observation unit 29 by a process such as decoding an information graphic, and provides the coordinates to the document processing unit 25.

  The document processing unit 25 controls the entire information processing system 1, and reads and executes corresponding processing routines stored in advance according to various processing execution instructions extracted from the client 10 via the instruction connection unit 21. To do. As a specific example, for example, in response to an execution instruction for displaying the next page of a document being displayed, information (processing information) related to the page currently displayed on the memory display 15 and document data are indicated. , 21, obtained from the non-volatile storage unit 13 via the connection control unit 22, executes layout processing for the next page based on the processing information and document data, and generates display data and a reaction map for the next page A series of processing routines of storing in the nonvolatile storage unit 13 via the instruction connection units 11 and 21 and the connection control unit 12 is stored, and this is executed.

Alternatively, in response to an execution instruction for extracting a display character string indicated from the displayed document, the coordinates (start point and end point coordinates of the character string to be extracted) specified in advance by the user from the calculation unit 30 are acquired. A series of processing routines are stored such that the document element displayed at the coordinates is inquired of the reaction extraction unit 18 and the character string data extracted from the reaction extraction unit 18 as output is temporarily stored. This is executed.
The power supply 26 is configured by a primary battery or a secondary battery, and supplies power to each unit (the instruction connection unit 21 of the host 20) of the information processing system 1.

<Operation of information processing system>
Next, the operation of the information processing system of this embodiment will be described.

<Basic operation>
The information processing system of this embodiment always operates according to the basic procedure shown in FIGS. 2 and 3A and 3B. The content of the processing corresponds to the determination result of the instruction connection unit 11 and is determined and executed using the coordinates obtained by the host 20 based on the coordinate pattern.
All processes are started by the host 20 instructing the client 10.

  Here, there are two cases of processing depending on whether or not the portion instructed by the host 20 is the instruction connection unit 11 of the client 10. Each can be determined by whether or not communication via the instruction connection unit 11 is activated. That is, when the host 20 detects that the tip of the operation instruction unit 28 has been touched, the connection control unit 22 applies an alternating current including a control signal to the antenna coil based on the power from the power source 26. At this time, if the coil of the instruction connection unit 21 is electromagnetically coupled to the coil provided in the instruction connection unit 11 of the client 10, the instruction connection unit 21 of the host 20 also changes impedance or depends on the client protocol. A connection is detected based on the initial response. On the other hand, if the instruction connecting units 11 and 21 do not approach the predetermined range, no impedance change or initial response occurs, and the connection remains undetected.

If a connection is not detected within a predetermined time, the host 20 performs a single process as shown in FIG. On the other hand, when the connection is detected, the host 20 and the client 10 cooperate with each other while communicating with each other as shown in FIGS.
First, a case where an instruction other than the instruction connection unit 11 is instructed will be described with reference to FIG. In this case, even if the user touches the client 10 at the tip of the operation connection unit 28 and the connection control unit 22 of the host 20 applies an alternating current including a control signal to the antenna coil, the communication is not activated (step S101). .

  In this case, the host 20 performs only position detection and storage thereof. That is, the host 20 irradiates the surface of the client 10 indicated by the tip of the operation connection unit 28 with the infrared light receiving and emitting unit 23, receives the reflected light, and outputs the light reception result to the observation unit 29. The Then, the observation unit 29 outputs a coordinate pattern of the indicated position to the calculation unit 30 as a detection result based on the output light reception result, and the calculation unit 30 calculates the coordinates indicated by the coordinate pattern, and the calculation result Are sequentially stored (steps S102 and S103). When these procedures are completed, the host 20 drives, for example, a vibrator (not shown) to notify the user of the detection completion (step S104), and the processing and the instruction operation are completed (step S105).

  Next, a case where the instruction connecting unit 11 is instructed will be described with reference to FIGS. In this case, when the user touches the instruction connection unit 11 of the client 10 with the tip of the operation connection unit 28 (step S201) and the connection control unit 22 of the host 20 applies an alternating current including a control signal to the antenna coil, the instruction connection is performed. Communication with the unit 11 is activated (steps S202 and S301). Here, the activated instruction connection unit 11 is identified based on the above (step S203), and the host 20 obtains its code. As a result, the document processing unit 25 inquires of the reaction extraction unit 18 about a process execution instruction corresponding to the instruction connection unit 11.

Then, the reaction extraction unit 18 extracts a corresponding process execution instruction from the reaction map based on the inquiry, and outputs the extraction result to the document processing unit 25 via the connection control unit 12 and the instruction connection units 11 and 21. In step S302, the document processing unit 25 starts executing a corresponding processing routine (step S204).
As described above, the document processing unit 25 executes the process based on the process execution instruction. Normally, this process is a process for a document being displayed, and the document processing unit 25 sends information (processing information) on the processing progress of the document currently displayed on the memory display 15 and the document data to the instruction connection unit 11. , 21, obtained from the nonvolatile storage unit 13 via the connection control unit 22, and performs processing based on the processing information and document data (step S 205).

  Depending on the processing executed here, data of coordinate detection results sequentially stored in the host 20 is used. For example, this corresponds to the case where the user sequentially instructs the document elements related to the processing on the memory display 15 and then touches the instruction connection unit 11 to instruct the processing contents. At this time, when processing the coordinate data, the document processing unit 25 inquires about the search for information corresponding to the reaction extraction unit 18 and refers to the document element output as a result. That is, in the process executed by the document processing unit 25, for example, when the document element displayed at the coordinate pointed to immediately before is set as the processing target, the document processing unit 25 sets the coordinate point pointed to immediately before. The value is referred to from the stored coordinate detection data, and the reaction extraction unit 18 is inquired about the document element displayed at the corresponding position by the coordinate value. Based on the inquiry, the reaction extraction unit 18 extracts a corresponding document element or dialogue element from the reaction map stored in the nonvolatile storage unit 13, and returns the extraction result to the document processing unit 25.

Various results can be considered as a result of the processing related to the document being displayed as described above, but when generalized, some change occurs in the display state after processing. In addition, when the display state is changed, the reaction process to be executed in response to the instruction is also updated. That is, the document processing unit 25 outputs an updated reaction map and display data as necessary as a result of the processing. The output display data and the reaction map are stored in the nonvolatile storage unit 13 via the instruction connection units 21 and 11 and the connection control unit 12 (steps S206, S207, S208, S209, S303, and S304). At this time, the display execution unit 17 sequentially displays the display data stored in the nonvolatile storage unit 13 on the storage type display 15 (step S305).
When these procedures are completed, the host 20 drives, for example, a vibrator (not shown) to notify the user of the detection completion (step S210), and the processing and the instruction operation are completed (steps S211 and S306).

<Page turning action>
Next, a page turning operation will be described as a specific processing example along the above basic operation. This operation is executed in response to an operation instructing the instruction connecting unit 11 that designates the movement to the next page or the instruction connecting unit 11 that designates the movement to the previous page. Hereinafter, a case will be described in which the user touches the uppermost instruction connection unit 11 of FIG. 1 to which movement to the next page is assigned with the tip of the operation instruction unit 28.

  In this example, in order to instruct the instruction connection unit 11, communication is activated as shown in FIGS. 3A and 3B based on the above (steps S201, S202, and S301). The activated instruction connection unit 11 is identified based on the above (step S203), and the host 20 obtains its code. Subsequently, the document processing unit 25 inquires of the reaction extraction unit 18 about a process execution instruction corresponding to the instruction connection unit 11.

  Then, the reaction extraction unit 18 extracts a corresponding process execution instruction from the reaction map based on the inquiry. In this example, an execution instruction for displaying the next page is extracted, and the extraction result is output to the document processing unit 25 via the connection control unit 12 and the instruction connection units 11 and 21 (step S302). A corresponding processing routine is executed (steps S204 and S205). By this processing routine, information (processing information) on the page currently displayed on the memory display 15 and document data are acquired from the nonvolatile storage unit 13 via the instruction connection units 11 and 21 and the connection control unit 22. The next page layout process is executed based on the processing information and the document data, and the next page reaction map is generated and stored in the nonvolatile storage unit 13 via the instruction connection units 21 and 11 and the connection control unit 12. (Reaction map is rewritten). Further, after the reaction map is rewritten, display data for the next page is generated and stored in the nonvolatile storage unit 13 via the instruction connection units 21 and 11 and the connection control unit 12 (steps S206, S207, S208, S209, S303, S304).

Then, the display execution unit 17 displays the display data stored in the nonvolatile storage unit 13 on the storage type display 15 (steps S305, S210, S211, and S306).
In the case of this processing, the procedure for extracting elements from the coordinates is not necessary.

<Character string extraction operation>
Next, a character string extraction operation will be described as another specific processing example in accordance with the above basic operation. This operation is executed according to a series of operations in which the user first designates the start point and end point of the displayed character string to be extracted and then instructs the instruction connecting unit 11 for designating character string extraction. Shall be.

  First, in order to specify a target character string, when the user touches the start point (memory display 15) of the character string to be extracted with the tip of the operation instruction unit 28, in this case, as shown in FIG. Communication is not activated (step S101). Therefore, the infrared ray receiving / emitting unit 23 irradiates the touched pixel with infrared rays and outputs a light reception result to the observation unit 29. The observation unit 29 outputs the coordinate pattern of the pixel as a detection result to the calculation unit 30 based on the output light reception result, and the calculation unit 30 calculates the coordinate indicated by the coordinate pattern, and the calculation result. Is stored (steps S102 and S103), and the procedure is completed (steps S104 and S105).

Similarly, when the user touches the end point of the character string to be extracted with the tip of the operation instruction unit 28, similarly, communication is not activated as shown in FIG. 2 (step S101), the infrared light receiving / emitting unit 23, The observation unit 29 and the calculation unit 30 store the coordinates of the end point in the calculation unit 30, and the procedure is completed (steps S102 to S105).
Finally, when the user touches the instruction connection unit 11 in the second stage of FIG. 1 to which execution of character string extraction is assigned with the tip of the operation instruction unit 28, the instruction connection unit 11 causes the instruction connection unit 11 of FIGS. As described above, communication is activated in the same manner as the page turning operation (steps S201, S202, and S301). The activated instruction connection unit 11 is identified based on the above (step S203), and the host 20 obtains its code. Subsequently, the document processing unit 25 inquires of the reaction extraction unit 18 about a process execution instruction corresponding to the instruction connection unit 11.

  Then, the reaction extraction unit 18 extracts a corresponding process execution instruction from the reaction map based on the inquiry. In this example, an execution instruction for extracting a character string is extracted, and the extraction result is output to the document processing unit 25 via the connection control unit 12 and the instruction connection units 11 and 21 (step S302). Thus, the corresponding processing routine is executed (steps S204 and S205). When the document processing unit 25 executes this processing routine, the coordinates sequentially instructed from the calculation unit 30 are acquired, the document element displayed at the coordinates is inquired to the reaction extraction unit 18, and the reaction extraction unit 18 is output as an output. The character string data extracted from is stored in the host 20 and the procedure is completed (steps S206 to S211, S303, S304 to S306). The document element is extracted by describing a reference instruction for document data in the reaction map and extracted by the reaction extraction unit 18 referring to the document data, or in a form accompanied by the document element in the reaction map. Either an extraction instruction is described and extracted without referring to the document data. In this process, the display data and the reaction map are not updated.

(1) As described above, in the information processing system 1 of the present embodiment, the client 10 stores the document data and the reaction map, and the document data displayed on the client 10 that has become communicable is transmitted from the client 10. The processing routine that is acquired and associated with the instruction connection unit 11 touched by the tip of the operation instruction unit 28 in the reaction map is executed on the document data. Therefore, for example, even if an operation assumed when using the plurality of clients 10 such as leaving the display contents as it is for a while and holding the display contents for a while and continuing the work later or giving it to another user is performed. By instructing the operation instruction unit 11 of the client 10 with the operation instruction unit 28, it is possible to execute appropriate processing based on the reaction map stored in the client 10, and while referring to the processing state and document data, The process can be performed recursively.

In addition, for example, when the client 10 is transferred to another user, there is no problem even if the host 20 that executes the process changes, and it is easy to transfer or rent to another user.
Further, the reaction extraction unit 18 of the client 10 extracts an execution instruction and document data from the reaction map and document data, and transmits the extraction result to the host 20. Therefore, the reaction extraction process via the instruction connection units 11 and 21 can be executed efficiently.

(2) In addition, the indication position of the operation instruction unit 28 is detected, and the character string extraction operation is performed based on the detection result. Therefore, for example, by instructing the displayed character string to be extracted by the operation instruction unit 28, an appropriate process can be executed based on the character string.
(3) Further, the coordinate pattern printed at the designated position of the operation instruction unit 28 is detected by the observation unit 29 of the host 20, and the coordinates are detected by the calculation unit 30 of the host 20 based on the detection result. did. Therefore, the client 10 does not need to operate at all, can provide an extremely inexpensive system, and can promote multiple use.

(4) In addition, the display execution unit 17 of the client 10 is made to rewrite the display state of the storage display 15 based on the display data stored in the nonvolatile storage unit 13 of the client 10. Therefore, it is possible to cause the client 10 to rewrite its own memory display body 15 and to efficiently perform display via the instruction connection units 11 and 21.
(5) Furthermore, since the reaction map stored in the nonvolatile storage unit 13 of the client 10 that has become communicable is rewritten with the reaction map generated by the host 20, the response map stored in the client 10 is used. And appropriate processing can be executed.

(6) Moreover, after rewriting the reaction map memorize | stored in the non-volatile memory | storage part 13, rewriting of the display state of the memory | storage display 15 of the client 10 was started. Therefore, for example, during rewriting of the display state, a user who has seen a part of the rewritten display content does not wait for the rewriting to end, and the operation connection unit 11 is newly instructed by the instruction connection unit 11 according to the display content. When this is done, it is possible to execute an appropriate process suitable for the user's intention.

(7) Further, the client 10 is operated by receiving power from the power supply 26 of the host 20. Therefore, since the host 20 can communicate with and operate only the necessary client 10 without a prior connection operation, wasteful procedures can be eliminated to the limit.
In the present embodiment, an example is shown in which all display data and reaction maps generated by the host 20 are output to the client 10, but the present invention is not limited to this. For example, only the changed part of the display data or the reaction map may be output to the client 10. This is preferable because the amount of information output from the host 20 to the client 10 can be reduced.

Specifically, the display data is generated separately from the display data generated immediately before and the update data, and only the update data is output from the host 20 to the client 10, and is stored in the nonvolatile storage unit 13 of the client 10. Only update data is additionally stored sequentially. Then, the display execution unit 17 partially drives (rewrites) the memory display 15 based on the update data.
Moreover, the update process which reflects update data in the display data memorize | stored in the non-volatile memory | storage part 13 may be performed, and the whole memory | storage display body 15 may be driven based on the display data after the reflection.

Further, in the reaction map, the reaction map and the update map generated immediately before are generated separately, and only the update map is output from the host 20 to the client 10, and the nonvolatile storage unit 13 of the client 10 stores the update map. Only the update map is additionally stored sequentially. When the character string extraction process is performed by the document processing unit 25, the latest update map is used with priority.
Alternatively, the update map may be updated by reflecting the update map in the reaction map stored in the client 10, and the updated response map may be used.

Furthermore, in the above, other methods can be used to determine whether or not the instruction connection unit 11 has been instructed. For example, a coordinate pattern similar to that on the surface of the memory display 15 is provided on the instruction connection unit 11. First, the host 20 acquires the coordinate value, and if it is within a predetermined range, the instruction is displayed. It may be determined that the connection unit 11 and the communication may be activated. If it does in this way, it is not necessary to try coil induction for every indication, and it can be set as a power-saving structure.
In addition, even when it is determined that the instruction connection unit 11 has been instructed, the coordinate value based on the coordinate pattern can also be used for the processing. For example, when the area of the instruction connection unit 11 is larger than the tip of the instruction connection unit 21, the instruction position in the range of the instruction connection unit 11 may be further determined.

  Moreover, although the example which extracts and outputs only required information in the reaction extraction part 18 of the client 10 was shown, it is not restricted to this. For example, not only document data but also the entire reaction map may be output from the client 10 to cause the host 20 to extract necessary information. At this time, document data and reaction maps may be cached so as to be held in the host 20 under predetermined conditions in preparation for processing the same client 10 continuously.

Second Embodiment
Next, a second embodiment of the host-based information system of the present invention will be described.
The second embodiment is different from the first embodiment in that information input / output between the client 10 and the host 20 is performed using infrared rays instead of coils.
Specifically, as shown in FIG. 4, the instruction connection unit 11 of the client 10 includes an infrared light receiving and emitting unit (optical communication module 19) instead of a coil for inputting and outputting information. In addition, the instruction connection unit 21 of the host 20 includes an infrared light receiving / emitting unit (light emitting unit = light transmitting / illuminating unit 31, light receiving unit = light receiving / imaging unit 32) instead of a coil for input / output of information.

In addition, the instruction | indication connection parts 11 and 21 are provided with the coil (electromagnetic coupling part (power transmission part / power reception part) for electric power feeding) for performing transmission / reception of electric power similarly to the said 1st Embodiment.
Thus, in the information processing system 1 of the present embodiment, information input / output between the client 10 and the host 20 is performed by infrared rays. Therefore, high-speed (16 Mbps, etc.) communication is possible with low power. In addition, when an electromagnetic coupling unit is provided to supply power to the client 10, the influence on communication is minimal. Furthermore, if the light transmitting / illuminating unit 31 and the light receiving / imaging unit 32 are also used in the illumination and imaging unit of the infrared light receiving / emitting unit 23 for optically reading the coordinate pattern (position information code) of the client 10, the components The number of points can be reduced, the cost can be reduced, and the operation instruction unit 28 can be downsized.

<Third Embodiment>
Next, a third embodiment of the host-based information system of the present invention will be described.
Conventionally, in a host-based information system, the host 20 is generally located at a remote location, and the host 20 performs a plurality of processes simultaneously by multitask / multithread processing. Displaying 10 information is not performed.
However, since the host 20 is in the vicinity of the client 10 and the processing is performed by switching the client 10 to be processed with a relatively coarse time granularity such as facing the client 10, it is possible to present specific processing information in the host 20. Is desirable.

  Therefore, in the third embodiment, as shown in FIG. 5, an information display unit 33 is provided in the operation instruction unit 28 of the host 20 so that the identification ID of the client 10 touched by the tip of the operation instruction unit 28 is displayed. I made it. Therefore, when a plurality of clients 10 are used, it is useful for the confirmation work by the user. Note that a method for discriminating the client 10 can be realized by differentiating the coordinate pattern and the ID for discriminating the instruction connection unit 11 for each client 10. In addition, a station ID may be assigned and exchanged during communication.

If the display status of the display data and reaction map to the client 10 and the transfer direction at that time (from the host 20 to the client 10 or from the client 10 to the host 20) are displayed on the information display unit 33, This is useful for grasping the progress of the operation by the user, and can prevent an unintended operation such as separating the tip of the operation instruction unit 28 from the client 10 during transfer. Furthermore, regarding the client 10 in operation, displaying information such as when the previous process was performed is useful for grasping and recollecting the operation history.
These information display requests are generated only for a short period of time, and thus are not suitable for the memory display 15, but are suitable for the host 20 without such problems.
In the present embodiment, the example in which the information display unit 33 is provided in the operation instruction unit 28 of the host 20 has been described. However, the present invention is not limited to this. For example, it may be provided in the main body of the host 20.

  As described above, in the above-described embodiment, the memory display 15 of FIG. 1 constitutes the display device described in the claims. Similarly, the nonvolatile storage unit 13 of FIG. 1 constitutes a map storage means and a display data storage means, the instruction connection unit 11 in FIG. 1 constitutes a client side connection means, the instruction operation unit 28 in FIG. 1 constitutes a host side connection means, and the position detection unit in FIG. 24, the observation unit 29 and the calculation unit 30 constitute position detection means, the document processing unit 25 in FIG. 1 constitutes document data acquisition means, the document processing part 25 in FIG. 1 constitutes processing execution means, and FIG. The processing unit 14 and the display execution unit 17 constitute display state rewriting means.

The host-based information system, the client, the host, the information system, the display terminal, and the control device of the present invention are not limited to the contents of the above-described embodiment, and are appropriately changed without departing from the spirit of the present invention. Is possible.
For example, conventionally, a host-based system has been expected to function as a network terminal independent of the client 10. Therefore, each client 10 needs to be equipped with relatively high-level independent functions such as a user interface processing function and a network terminal function, and the manufacturing cost and the management cost cannot be sufficiently reduced.
Therefore, for example, an information service (data store, network communication) that can be used from the document processing unit 25 of the host 10 may be provided. By doing so, the application of the document processing unit 25 can perform various and advanced processes relatively easily.
