Deter. The line sensor 515 receives reflected light corresponding to the illumination light from the illumination unit (light source) 521, and outputs a luminance signal (brightness information) corresponding to each of the background portion and the bar portion. The lenticular lens unit 517 guides the reflected light from the barcode of the object illuminated by the light source 521 to the line sensor 515.

  As shown in FIG. 9, the light source (illuminating unit) 521 outputs illumination light so that the line sensor 515 located at a predetermined position of the globe body 503 can receive reflected light from the barcode of the reading target unit. The light source 521 includes, for example, an LED (Light Emitting Diode) array 523 and a protection member 525 that covers and protects the LED array 523 and gives the LED array 523 flexibility. The LED array 523 includes any number of LED elements. The protective member 525 holds individual LED elements, and is useful for outputting illumination light even when the glove body 503 is deformed based on the movement of the wearer's hand or the like due to its own flexibility. .

  The lighting control unit 534 lights one of the light sources 521 of the first and second barcode readers 505 and 507 under the control of the CPU 532.

  The line sensor 515 of the barcode reader on the side corresponding to the light source lit by the lighting control unit 534 receives the light reflected from the barcode of the object, and photoelectrically converts the received light to A− D-converted and output to the image processing unit 535.

  The image processing unit 535 analyzes (encodes) the barcode information subjected to the A / D conversion, and converts the barcode information into a code string (barcode information signal) having a predetermined format corresponding to the barcode information. The image processing unit 535 also supplies the barcode information signal to the information management server 1201 via the communication module 536 and the network NTW.

  The communication module 536 notifies the information management server 1201 or the system controller 1202 of the position of the barcode reader through the network NTW.

  The position detection unit 537 specifies the position of the barcode reader itself based on position information using, for example, GPS (Global Positioning System) or position information using short-range wireless communication such as iBeacon.

  In addition, it is preferable that the signal processing unit 531 has a power source by a battery or a rechargeable battery (secondary battery) at an arbitrary position in the glove body 503 and can operate by the barcode reader 501 alone. Further, the communication module 536 of the signal processing unit 531 may be provided independently of the barcode reader 501, for example, and may be connected to the signal processing unit 531 by wire, for example.

  FIG. 11 shows that when an identified worker wears the wearable terminal shown in FIGS. 2 and 3 and performs the work, the display area of the wearable terminal further wears an electronic device that cooperates with the wearable terminal. It is the schematic which shows the example of a display which displays the information for a wearer's work assistance to be visible on extension of a wearer's eyes | visual_axis. 12 to 15 are diagrams illustrating an example of processing related to the display in FIGS. 11 (a) to 11 (d). 12 is an example of processing related to the display of FIG. 11A, FIG. 13 is an example of processing related to the display of FIG. 11B, and FIG. 14 is an example of processing related to the display of FIG. FIG. 15 shows an example of processing related to the display of FIG.

  As described above, the latest position information of the wearable terminals 1100-1 to 1100-m and the barcode readers 501-1 to 501-p is stored in the information management server 1201 or the system controller 1202. The information management server 1201 cooperates with the wearable terminals 1100-1 to 1100-m using the position information of the wearable terminals 1100-1 to 1100-m and the position information of the barcode readers 501-1 to 501-p. The barcode readers 501-1 to 501-p to be searched are searched.

  The information management server 1201 searches the position information of the wearable terminals 1100-1 to 1100-m and the position information of the barcode readers 501-1 to 501-p. The reader 501-y is determined as an electronic device that cooperates with the wearable terminal 1100-x. As described above, the barcode readers cooperating with the wearable terminals 1100-1 to 1100-m are determined by matching each other's position information.

  When the barcode reader 501-y is determined as an electronic device that cooperates with the wearable terminal 1100-x, the information management server 1201 transmits the attribute information y of the barcode reader 501-y to the wearable terminal 1100-x. The attribute information y includes identification information that can uniquely identify the barcode reader 501-y. The identification information is, for example, the manufacturing number or serial number of the barcode reader 501 -y, or a management number assigned to the barcode reader 501 -y in the system managed by the system controller 1202.

  The wearable terminal 1100-x that has received the attribute information of the barcode reader 501-y is an electronic device that cooperates with the wearable terminal 1100-x as shown in FIGS. 11A to 11D based on the received attribute information. A process of displaying information for supporting the work of the wearer who further wears the device (bar code reader 501-y) in the display area 1106 a of the screen 1106 is started.

  FIG. 11A shows, for example, that the wearable terminal 1100-x cooperates in a ready (standby) state in which a specified worker wears the wearable terminal 1100-x and the barcode reader 501-y. This is an example of a display that displays in the display area 1106a of the screen 1106 that the management number of the barcode reader 501-y to be started is “No. 3”.

  Note that the position information of the wearable terminal 1100-x and the position information of the barcode reader 501-y are the same as the ready (standby) state in which the worker wears the wearable terminal 1100-x and the barcode reader 501-y. The information management server 1201 searches the position information of the wearable terminals 1100-1 to 1100-m and the barcode readers 501-1 to 501-p, so that the barcode reader 501-y becomes the wearable terminal 1100-x. The electronic device is confirmed as an electronic device to cooperate with, or the confirmation is expected to be completed promptly.

  FIG. 12A shows an example of processing of the wearable terminal 1100-x in the display example of FIG. Assume that the information management server 1201 determines that the barcode reader 501 -y cooperates with the wearable terminal 1100 -x. With this determination, the information management server 1201 transmits the attribute information of the barcode reader 501-y to the wearable terminal 1100-x. When the wearable terminal 1100-x receives the attribute information y of the barcode reader 501-y by the communication module 305, the light projecting unit 1102 uses the attribute information y of the cooperating barcode reader 501-y to generate a barcode reader. The process for displaying the work support information regarding 501-y in the display area 1106a of the screen 1106 is started (S100).

  The light projecting unit 1102 acquires the received attribute information y of the barcode reader 501-y (S101), and displays information included in the attribute information y, for example, a management number, in the display area 1106a of the screen 1106 ( S102).

  As shown in FIG. 12B, the attribute information z of the barcode reader 501-z that has been saved in the light projecting unit 1102 and cooperated immediately before, and the attribute information y of the barcode reader 501-y. (S113) and only when it is confirmed that the attribute information has changed, information included in the attribute information y of the barcode reader 501-y that starts cooperation, for example, the management number is displayed on the screen 1106. You may display on the display area 1106a (S115).

  FIG. 11B shows, for example, that the wearable terminal 1100-x immediately collaborates in a ready (standby) state in which a specified worker wears the wearable terminal 1100-x and the barcode reader 501-y. Based on the contents of the attribute information z of the activated barcode reader-z, in addition to the fact that the management number of the barcode reader that starts cooperation is “No. 3”, the barcode reader that starts cooperation Is an example of a display that displays in the display area 1106a of the screen 1106 that the barcode has been changed from the barcode reader that cooperated immediately before.

  FIG. 13A shows an example of processing of the wearable terminal 1100-x in the display example of FIG. Assume that the information management server 1201 determines that the barcode reader 501 -y cooperates with the wearable terminal 1100 -x. With this determination, the information management server 1201 transmits the attribute information of the barcode reader 501-y to the wearable terminal 1100-x. When the wearable terminal 1100-x receives the attribute information y of the barcode reader 501-y by the communication module 305, the light projecting unit 1102 uses the attribute information y of the cooperating barcode reader 501-y to generate a barcode reader. Processing for displaying the work support information regarding 501-y in the display area 1106a of the screen 1106 is started (S120).

  The light projecting unit 1102 acquires the attribute information y of the received barcode reader 501-y (S121). In addition, the light projecting unit 1102 acquires the attribute information z of the barcode reader 501-z that has been stored in the light projecting unit 1102 and cooperated immediately before (S122), and compares the attribute information y with the attribute information z. (S123). If they match as a result of the comparison (S124), the light projecting unit 1102 determines that the barcode reader 501-z that cooperated immediately before is the same as the barcode reader-y that will start cooperation from now on, The processing ends without displaying anything in the display area 1106a of the screen 1106 (S126). If they do not match as a result of the comparison, the light projecting unit 1102 determines that the barcode reader 501 -z that cooperated immediately before is not the same as the barcode reader -y that will start cooperation from now on, and in the attribute information y In addition to the fact that the management number of the barcode reader that starts the cooperation is “No. 3” using the information included in the information, for example, the management number, it is changed from the barcode reader that cooperated immediately before Is displayed in the display area 1106a of the screen 1106 (S125).

  As shown in FIG. 13B, even if the barcode reader 501 -z and the barcode reader 501 -y that cooperated immediately before are not changed (S 134), the barcode reader -y that starts the collaboration does not change. Using the information included in the attribute information y (= attribute information z), for example, the management number, a message indicating that the management number of the barcode reader that starts cooperation is “No. 3” is displayed in the display area 1106a of the screen 1106. (S136) may be performed.

  FIG. 11C shows, for example, that the wearable terminal 1100-x cooperates in a ready (standby) state in which a specified worker wears the wearable terminal 1100-x and the barcode reader 501-y. In addition to the fact that the management number of the barcode reader 501-y to be started is “No. 3”, the management number “No. 1” of the barcode reader exists around the wearable terminal 1100-x. 6 is an example of a display displayed on a display area 1106a of a screen 1106.

  As described above, the information management server 1201 searches the position information of the wearable terminals 1100-1 to 1100-m and the position information of the bar code readers 501-1 to 501-p. The barcode reader 501 -y to be used is determined as an electronic device that cooperates with the wearable terminal 1100 -x. After being determined as the cooperating electronic device, the information management server 1201 can also search for and extract a barcode reader existing around the wearable terminal 1100-x. The information management server 1201 that has searched and extracted a barcode reader existing around the wearable terminal 1100-x, in addition to the attribute information y of the barcode reader 501-y that cooperates with the wearable terminal 1100-x. The attribute information of the barcode reader extracted as a barcode reader existing in the vicinity is also transmitted. The wearable terminal 1100-x that has received the attribute information y of the barcode reader 501-y and the attribute information of the barcode reader existing in the vicinity is arranged around the wearable terminal 1100-x as shown in FIG. The management number of the existing barcode reader is also displayed in the display area 1106a of the screen 1106.

  FIG. 14A shows an example of processing of the wearable terminal 1100-x in the display example of FIG. The processing of FIG. 14A is the same as the processing of FIG. 13A, the processing of acquiring attribute information of the barcode reader existing in the vicinity from the sent attribute information (S142), and the acquisition A process (S146) for displaying the attribute information of the barcode reader existing in the vicinity on the display area 1106a of the screen 1106 using the information is added. Similarly, the process of FIG. 14B is similar to the process of FIG. 13B, in which the attribute information of the barcode reader existing in the vicinity is acquired from the sent attribute information (S152), A process (S156 / S157) for displaying the attribute information of the barcode reader existing in the vicinity on the display area 1106a of the screen 1106 using the acquired information is added.

  As shown in FIG. 14B, the attribute information z of the barcode reader-z that has been stored in the light projecting unit 1102 and cooperated immediately before and the attribute information y of the barcode reader 501-y are stored. Even if it does not change (S154), management of the barcode reader that starts cooperation using information included in the attribute information y (= attribute information z) of the barcode reader-y that starts cooperation, for example, a management number The fact that the number is “No. 3” and the presence of the barcode reader having the management number “No. 1” in the vicinity may be displayed in the display area 1106a of the screen 1106 (S157).

  In the examples of FIGS. 11A to 11C described above, the barcode readers 501-1 to 501-p are examples in which any wearable terminal 1100-1 to 1100-m can cooperate. . However, depending on the wearable terminal, only a specific barcode reader is allowed to cooperate. In such a case, the system controller 1202 can individually set a barcode reader that permits cooperation for each of the wearable terminals 1100-1 to 1100-m.

  FIG. 16 is a list of bar code readers permitted to cooperate with each of the wearable terminals 1100-1 to 1100-m. Information managed in the list of bar code readers permitted to cooperate is based on attribute information of the wearable terminals 1100-1 to 1100-m and bar code readers 501-1 to 501-p. In the example of the list of FIG. 16, the managed information is the management assigned to the wearable terminals 1100-1 to 1100 -m and the barcode readers 501-1 to 501-p in the system managed by the system controller 1202. This is the case where numbers are managed. A list of bar code readers allowed to cooperate is managed by the system controller 1202 and updated as needed. A list of barcode readers permitted to cooperate is transmitted from the system controller 1202 to the wearable terminals 1100-1 to 1100-m at least at the update timing.

  FIG. 11D shows a barcode that is permitted to cooperate in a ready (standby) state in which, for example, a specified worker wears the wearable terminal 1100-x and the barcode reader 501-y. When it is determined from the reader information that the barcode reader 501-y worn by the worker is not permitted to cooperate, the wearable terminal 1100-x displays the fact in the display area 1106a of the screen 1106. It is an example of the display to perform.

  FIG. 15 shows an example of processing of the wearable terminal 1100-x in the display example of FIG. Assume that the information management server 1201 determines that the barcode reader 501 -y cooperates with the wearable terminal 1100 -x. With this determination, the information management server 1201 transmits the attribute information of the barcode reader 501-y to the wearable terminal 1100-x. When the wearable terminal 1100-x receives the attribute information y of the barcode reader 501-y by the communication module 305, the light projecting unit 1102 uses the attribute information y of the cooperating barcode reader 501-y to generate a barcode reader. Processing for displaying the work support information regarding 501-y in the display area 1106a of the screen 1106 is started (S160).

  The light projecting unit 1102 acquires the attribute information y of the received barcode reader 501-y (S161). In addition, the light projecting unit 1102 acquires information on a list of barcode readers that are already stored in the light projecting unit 1102 and permitted to cooperate (S162). Based on the list of bar code readers permitted to cooperate, it is determined whether or not the bar code reader 501 -y having received the attribute information in S 161 is permitted to cooperate with the wearable terminal 1100 -x. (S163). If it is determined that the bar code reader 501 -y worn by the operator is not permitted to cooperate with the wearable terminal 1100 -x, the light projecting unit 1102 is appropriately used. Is displayed on the display area 1106a of the screen 1106 (S164).

  The process for displaying the work support information related to the barcode reader 501 -y in FIGS. 12 to 15 on the display area 1106 a of the screen 1106 of the wearable terminal 1100 -x is the wearable terminal 1100-1 as described above. Processing for determining ~ 1100-m and the barcode readers 501-1 to 501-p cooperating therewith is the processing in the information management server 1201. However, the wearable terminals 1100-1 to 1100-m sequentially receive the attribute information including the position information of the barcode readers 501-1 to 501-p from the information management server 1201, so that the wearable terminals 1100-1 to 1100- As a process in m, it is also possible to determine the cooperating bar code reader by comparing the received bar code readers 501-1 to 501-p with the own position information.

  FIG. 17 is a schematic diagram illustrating a basic concept of a detection system according to an embodiment that uses light leaked from a light source unit of a wearable terminal. That is, the position of the wearable terminal (wearer) and the state of the wearer can be detected by using the leaked light from the wearable terminal shown in FIGS.

  The detection system illustrated in FIG. 17 includes one or more wearable terminals 1100 (−1 to −m), one or more sensor wireless chips 1204 (−1 to −n), and one system controller 1202. In addition, they can exchange information by communication between them. The communication between each other may be either wired or wireless. For example, short-range wireless communication, particularly Bluetooth (Bluetooth) is preferable. More preferably, they cooperate with each other by short-range wireless communication, so that they are not affected by free movement (or change of arrangement location) of wearable terminal 1100 (or sensor wireless chip 1204), and cooperated operation and processing Is possible.

  In the detection system of the embodiment, wearable terminal identification information (hereinafter referred to as terminal ID) is used to identify individual identification information, that is, an arbitrary number of wearable terminals 1100 in the light 1108 output from the light source unit 1104 of the wearable terminal 1100. The signal is intermittently modulated using information including (The light 1108 emitted from the light source unit 1104 is modulated with an information signal including a terminal ID.) That is, in the detection system of the embodiment, the wearable terminal 1100 is used as an “information transmission source” using the leaked light 1118. To do. As described above, the wearable terminal 1100 can be multi-functionalized by providing the information transmission function in addition to the display function widely known. Thereby, the diversity of the system including the wearable terminal 1100 can be achieved.

  As a method for modulating the light emission amount of the light source unit 1104, for example, a chopper type modulation method that reduces the light emission amount to zero is not used, and a modulation method that can ensure a light emission amount equal to or greater than a predetermined amount even when the light emission amount is low is adopted. Thereby, the burden with respect to a wearer's eyes can be reduced. As the modulation method, for example, a DSV (Digital Sum Value) -free modulation method (that is, a modulation method in which a DSV of a signal after modulation is always calculated and a bit inversion code can be inserted as appropriate so that a direct current component is zero) is employed. Thereby, it is possible to suppress a change in the light emission amount in a relatively long range (macroscopic change in the light emission amount can always be zero), and the burden on the wearer's eyes can be further reduced.

  Since the human eye can recognize a change of about 0.02 seconds, setting the reference frequency of the modulation to 10 Hz or higher, for example, 20 Hz or higher, more preferably 60 Hz or higher, reduces the burden on the wearer's eyes. An effect is also born. On the other hand, since the LED used for the light source unit 1104 has an internal impedance and a connection capacitance, the accurate modulation frequency is preferably less than 100 MHz, preferably 10 MHz or less. Therefore, the reference frequency of the light source unit 1104 used in the detection system of the embodiment is preferably 10 Hz to 100 MHz, and more preferably 10 Hz to 10 MHz.

  In the detection system of the embodiment, leaked light 1118 that is diverging light from the light source unit 1104 is used. As a result, the amount of light detected by the sensor wireless chip 1204 changes according to the distance δ between the wearable terminal 1100 and the sensor wireless chip 1204. By using this phenomenon, the distance between the wearable terminal 1100 and the sensor wireless chip 1204 (or the direction of the wearable terminal 1100 with respect to the sensor wireless chip 1204) can be predicted.

  By using divergent light as the leaked light 1118 from the light source unit 1104, the above light can be detected in a relatively wide range. As a result, it is possible to detect the position of the wearable terminal 1100 (distance between the wearable terminal 1100 and the sensor wireless chip 1204) and the direction (sensor wireless) only by installing a relatively small number of sensor wireless chips 1204 (-1 to -n). The direction of wearable terminal 1100 with respect to chip 1204) can be detected. Thereby, the installation cost required in order to install a detection system can be reduced.

  The light amount information of the leakage light 1118 (transmitted light 1158) from the light source unit 1104 detected by the sensor wireless chip 1204 is transmitted from the sensor wireless chip 1204 to the system controller 1202 (or information management server 1201) at a predetermined timing. The system controller 1202 analyzes information from the sensor wireless chip 1204 collected by the system controller 1202 (or collected in the information management server 1201). Thereby, it is possible to estimate an arbitrary wearable terminal 1100 (−1 to −m), that is, the position of the wearer and the state of the wearer.

  In the embodiment shown in FIG. 17, the sensor wireless chip 1204 is fixed on a work table 1206 (rack or work space A01 to Axy, B01 to Bxy, C01 to Cxy,..., X01 to XYxy in FIG. 1). The wearable terminal 1100 is movable. However, the present invention is not limited to this, and the sensor wireless chip 1204 (and the work table 1206) may be movable. In that case, the distribution state of the sensor wireless chip 1204 (and the work table 1206) may be read by the wearable terminal 1100 arranged at a fixed position (fixed position).

  FIG. 18 is a schematic diagram illustrating a specific usage example of the system for recognizing an electronic device according to the embodiment.

  18 illustrates an example in which the system (work area 1001 in FIG. 1) managed by the system controller 1202 is divided into two sections 1210-1 and 1210-2. Sections 1210-1 and 1210-2 may be, for example, truncated partitions.

  In FIG. 18, wearable terminals 1100-1 (first wearer) and 1100-2 (second wearer) move in section 1210-1, and wearable terminal 1100-3 (third wearer) moves. Consider the case of being located at a predetermined position in section 1210-2 (mainly staying at a constant position). It is assumed that four sensor wireless chips (position information transmitting units) 1204-1 to 1204-4 are installed in the section 1210-1. The amount of light (leakage light 1118) from any wearable terminal 1100 (-1 to -3) in section 1210-1 is detected by each sensor wireless chip 1204-1 to 1204-4. Each of the sensor wireless chips 1204-1 to 1204-4 performs AD (Analog-Digital) conversion on the amount of light (leakage light 1118) detected in each of them to obtain light amount information corresponding to the amount of light at a predetermined timing. And transmitted to the system controller 1202 by short-range wireless communication.

  18, the wearable terminal 1100-1 moves in the direction of the sensor wireless chip 1204-1 in accordance with the movement of the wearer, and at the same time, the direction of the wearable terminal 1100-2 is an arbitrary operation of the wearer, such as swinging (nodding) Consider a case where the head changes temporarily according to the turning of the head. FIG. 19 shows changes in detection information in time series in the system controller 1202 at this time.

  FIG. 19 illustrates an example in which an intermittent time change method is used as a modulation method of leaked light 1118 (transmitted light 1158) from each light source unit 1104 of wearable terminals 1100-1 to 1100-3. That is, in each of the wearable terminals 1100-1 to 1100-3, the modulation timing is shifted (the modulation period of each wearable terminal is shifted).

  As shown in FIG. 19, for the first wearable terminal 1100-1, the ID modulation period 1304 of the wearable terminal is intermittently set, and in other periods, the non-modulation period 1302 is entered. Within the ID modulation period 1304 of the first wearable terminal 1100-1, the synchronization signal SYNC (FIG. 19 (l)) and wearable terminal identification information (identification, hereinafter referred to as terminal ID) constitute one set (one pair). 1). The set is repeated a plurality of times (in the example shown in FIG. 19, a multiple of 4 in accordance with the number (n) of the sensor wireless chips 1204 (−1 to −n)).

  At the same time as the first wearable terminal 1100-1 enters the non-modulation period 1302, the ID modulation period 1306 of the second wearable terminal 1100-2 starts. Similarly, at the same time as the second wearable terminal 1100-2 enters the non-modulation period 1302, the ID modulation period 1308 of the third wearable terminal 1100-3 starts.

  In the ID modulation period 1306 of the second wearable terminal 1100-2 and in the ID modulation period 1308 of the third wearable terminal 1100-3, the synchronization signal SYNC (FIG. 19 (l)) and the individual wearable terminals 1100 The identification information (terminal ID) is repeatedly modulated. As described above, by putting identification information (terminal ID) of each wearable terminal 1100 in the modulated signal, the identification information (terminal ID) can be detected in the system controller 1202. Thereby, the system controller 1202 can confirm the identification information (terminal ID) of the wearable terminal in parallel with the detection timing, so that the identification accuracy of the wearable terminal is improved.

  In the above example, the modulation timings of wearable terminals 1100-1 to 1100-3 are time-division (intermittent). However, in the detection system of the embodiment, for example, it is assumed that all wearable terminals 1100-1 to 1100-3 are continuously modulated, and each modulation reference of wearable terminals 1100-1 to 1100-3 is used. The frequency may be changed. In addition, each frequency spectrum characteristic at the time of spectrum spreading may be changed.

  As shown in FIGS. 19D to 19G, the information communication period 1310 from the sensor wireless chip is finely divided into time. In each of the sensor wireless chips 1204-1 to 1204-4, the communication timing with the system controller 1202 is shifted from each other. This communication timing is managed by the system controller 1202.

  In FIG. 18, at the initial time, a part of the leaked light 1118-1 from the light source unit 1104 of the wearable terminal 1100-1 reaches the sensor wireless chip 1204-4. Therefore, at the initial time, as shown in FIG. 19 (k), the sensor wireless chip 1204-4 detects the modulated leakage light 1118-1 from the light source unit 1104 of the wearable terminal 1100-1. However, as wearable terminal 1100-1 moves toward sensor wireless chip 1204-1, modulation of leaked light 1118-1 from light source unit 1104 of wearable terminal 1100-1 detected by sensor wireless chip 1204-4 is detected. The signal amplitude decreases (FIG. 19 (k)). On the other hand, the modulation signal amplitude of the leaked light 1118-1 from the light source unit 1104 of the wearable terminal 1100-1 detected by the sensor wireless chip 1204-1 increases with time. As described above, the wearable terminal 1100 (−1 to −−), which is the detection target, is compared in the system controller 1202 by comparing the time variation of the modulation signal amplitude detected by each sensor wireless chip 1204 (−1 to −n). The time change (movement state) of the position of m) can be estimated.

  On the other hand, when wearable terminal 1100-2 is facing the direction of sensor wireless chip 1204-3 at the initial time, the modulation signal amplitude obtained from leaked light 1118-2 from the light source is sensor wireless chip 1204-. The detection amount at the sensor wireless chip 1204-3 is larger than the detection amount at 2. At this time, for example, consider a case where the wearer swings his head and temporarily faces the sensor wireless chip 1204-2. Then, the detection output (of the wearable terminal 1100-2) output by the sensor wireless chip 1204-2 is temporarily corresponding to the leaked light 1118-2 ′ from the light source unit 1104 as shown in FIG. 19 (i). Increase (decrease afterwards). On the other hand, the detection output (of the wearable terminal 1100-2) output from the sensor wireless chip 1204-3 temporarily corresponds to the leaked light 1118-2 ′ from the light source unit 1104 as shown in FIG. After it decreases, it increases again.

  In this way, by comparing the time change of the modulation signal amplitude detected by each sensor wireless chip 1204 in the system controller 1202, the direction of the wearable terminal 1100 (-1 to -m) (to be detected) is determined. Time change can also be estimated.

  The detection example described above shows an example in which the movement of the wearer is movement of the wearer or swinging of the wearer. However, the present invention is not limited to this, and various other actions of the wearer may be used. For example, the leakage light 1118-2 from the light source unit 1104 may be temporarily blocked by movement of the wearer's hand or intentional twist of the upper body (by the wearer). In this case, in all the sensor wireless chips 1204-1 to 1204-4, the modulation signal amplitude temporarily decreases in common (in the same time zone). In this way, by comparing the relevance of changes in the modulation signal amplitudes of all the sensor wireless chips 1204-1 to 1204-4, it becomes possible to identify different behavior patterns of the user.

  By using the above method, it is possible not only to grasp the user's behavior but also to communicate the user's intention to the system controller 1202. As a result, not only unilaterally receiving information from the system controller 1202 but also bidirectional information transmission between the user and the system controller 1202 is possible.

  As described above, information for supporting the work of the wearer who wears the wearable terminal worn by the worker and the electronic device cooperating with the wearable terminal is displayed on the display function of the wearable device worn by the worker. As a result, it is possible to present to the worker information relating to the electronic device that cooperates with the wearable terminal to be mounted in real time, and the working efficiency of the worker can be improved.

  For example, an operator generally removes a wearable terminal that has been worn and a barcode reader that cooperates with the wearable terminal during a break. When the worker resumes work after the break time, when the worker again wears the wearable terminal and the barcode reader that cooperates with the wearable terminal to work, as shown in FIG. Can visually check the management number of the attached barcode reader displayed in the display area 1106a of the screen 1106 of the wearable terminal in real time. Thereby, the worker can receive support for work and work efficiency can be improved.

  Further, when the combination of the wearable terminal worn by the operator and the barcode reader is different before and after the break, as shown in FIG. 11B, the management number of the attached barcode reader In addition, the bar code reader attached after the break is displayed on the display area 1106a of the screen 1106 of the wearable terminal to indicate that the bar code reader attached after the break is different from the bar code reader attached before the break. Reader confirmation can be made easier.

  Furthermore, as shown in FIG. 11 (c), not only the management number of the attached barcode reader, but also the numbers of barcode readers existing in the vicinity thereof are displayed on the screen 1106 of the wearable terminal. By displaying in the area 1106a, it is possible to make the wearer confirm whether there is a mistake in taking the barcode reader, and the work accuracy can be improved.

  Furthermore, by determining in advance a barcode reader that can cooperate with the wearable terminal, as shown in FIG. 11 (d), when there is a mistake in taking the barcode reader after a break, the attached barcode is By making it possible to visually check the management number of the reader in real time, it is possible to eliminate in advance the adverse effects on subsequent work due to mistakes.
