(First embodiment)
FIG. 1 is a configuration diagram showing a remote work support system including an information presentation apparatus according to the first embodiment of the present invention. In this remote work support system, an information presentation device 100, an information setting device 200, and a setting information database (setting information DB) 24 can be connected via a communication network NW.
The communication network NW is configured by a LAN (Local Area Network) if the system is constructed in, for example, an office or an office. On the other hand, when the system is configured across a plurality of offices or offices, the system is configured by a computer network represented by the Internet.

  In the setting information DB 24, presentation information related to work input by the remote instructor from the data input unit 22 of the information setting device 200 is stored in a plurality of presentation modes (text data, video data, and audio data). . Furthermore, a first presentation information selection table for selecting these presentation information is stored. FIG. 3 shows the configuration of the first presentation information selection table stored in the setting information DB 24. The first presentation information selection table stores a text file name, a video file name, an audio file name, and a top priority selection file name for each projection object.

  The information presentation apparatus 100 is installed at a work site where a field worker is present, and includes an information presentation unit 2 and an environmental condition detection unit 12. In addition, the information presentation apparatus 100 is connected with a camera 1, a projector 6, a speaker 9, an illuminance meter 11, and a sound level meter 16. The camera 1 images a work area including the work object 25, and the projector 6 displays a projection object 27 indicating that presentation information related to the work object 25 exists. As shown in FIG. 1, it is assumed that the imaging range of the camera 1 and the projection range of the projector 6 are adjusted to coincide.

  Further, the speaker 9 outputs a work instruction or the like loudly based on the audio data sent from the information setting device 200. The illuminometer 11 measures the illuminance at the work site, and inputs the measured illuminance value to the information presentation apparatus 100 as illuminance value data. The sound level meter 16 measures the noise level at the work site, and inputs the measured noise level to the information presentation apparatus 100 as noise value data.

  The information presentation unit 2 includes an image storage unit 3, an image processing unit 4, an image transmission unit 5, a display / processing control unit 7, a database search unit (DB search unit) 8, and an output control unit 10. . The image storage unit 3 stores image data obtained by imaging a work area including the work object 25 input from the camera 1. The image processing unit 4 acquires a difference image for each frame from the captured image of the camera 1 stored in the image storage unit 3 and extracts a feature region. Then, the barycentric coordinates of the extracted feature region are calculated.

  Specifically, in order to display the processing content associated with the projection object 27 by the field worker, when the projection object 27 is indicated using the pointing tool 26 such as a laser pointer, the laser pointer is used as a feature region. Only the designated area is extracted, and its barycentric coordinates are detected. Using the barycentric coordinates, the DB search unit 8 searches the setting information DB 24 to display the presentation information associated with the projection object 27. Further, the image transmission unit 5 transmits the image data stored in the image storage unit 3 to the information setting device 200 via the communication network NW.

  The DB search unit 8 accesses the setting information DB 24 and acquires the presentation information related to the projection object 27 identified by the image processing unit 4 in the presentation mode determined by the determination unit 15 described later. If the acquired presentation information is video or text data, the DB search unit 8 inputs the presentation information to the display / processing control unit 7. The display / processing control unit 7 creates projection image data based on the presentation information input from the DB search unit 8, and outputs the created projection image data to the projector 6. The projector 6 projects the presentation information on the work area based on the projection image data. On the other hand, in the DB search unit 8, when the obtained presentation information is audio data, the presentation information is input to the output control unit 10. The output control unit 10 outputs the presentation information, which is audio data, to the speaker 9, and the speaker 9 amplifies and outputs the presentation information based on the audio data.

  The environmental condition detection unit 12 includes an illuminance data acquisition unit 13, an illuminance data storage unit 14, a determination unit 15, a noise data acquisition unit 17, and a noise data storage unit 18. The illuminance data acquisition unit 13 acquires the illuminance value measured by the illuminometer 11 and stores it in the illuminance data storage unit 14 as illuminance value data. The noise data acquisition unit 17 acquires the noise level at the work site measured by the sound level meter 16 and stores it in the noise data storage unit 18 as noise value data.

  The determination unit 15 compares the illuminance value stored in the illuminance data storage unit 14 and the noise value stored in the noise data storage unit 18 with predetermined threshold values, respectively, and presents the presentation information as text data, video data, or audio. It is determined in which presentation mode of the data the data is presented. Then, the determined presentation mode is output to the DB search unit 8. The threshold value is set in advance for each of the illuminance value and the noise value. The threshold value of the illuminance value is an upper limit value of the illuminance at the work site where the projection image by the projector 6 can be recognized. The threshold value of the noise value is an upper limit value of the noise level at the work site set within a range in which the site worker can recognize the sound output from the speaker 9.

  On the other hand, the information setting device 200 used by the remote instructor includes an image receiving unit 19, a display unit 21, and a data input unit 22. The image receiving unit 19 receives image data sent from the information presentation apparatus 100 via the communication network NW. The display unit 21 is composed of a liquid crystal display (LCD) or the like, and displays the received image data. The data input unit 22 includes an input device such as a keyboard and a mouse (not shown), and receives data input by the remote instructor using these input devices. Data such as presentation information related to work input by the data input unit 22 is stored in the setting information DB 24.

  Next, the operation of the information presentation apparatus 100 configured as described above will be described. FIG. 2 is a flowchart showing a processing procedure of the information presentation operation in the information presentation apparatus 100 and its processing contents. Prior to this, it is assumed that the site worker has performed an operation of presenting presentation information associated with the projection object 27 using the pointing tool 26, for example, text information and video information regarding the work procedure.

  First, in step S <b> 2 a, the illuminance data acquisition unit 13 of the information presentation apparatus 100 measures the illuminance value at the work site with the illuminance meter 11 and stores the input illuminance value in the illuminance data storage unit 14. At the same time, in step S <b> 2 b, the noise data acquisition unit 17 measures the noise level at the work site using the sound level meter 16 and stores the input noise value in the noise data storage unit 18.

  Next, in step S <b> 2 c, the environmental condition detection unit 12 of the information presentation device 100 is preset with the illuminance value and the noise value stored in the illuminance data storage unit 14 and the noise data storage unit 18 in the determination unit 15. Compare with each threshold. In this comparison, first, it is determined in step S2d whether or not the illuminance value is equal to or greater than a predetermined threshold value. If it is determined by the determination of the illuminance value that the illuminance value is equal to or greater than the predetermined threshold value, the process proceeds to step S2h to determine whether or not the noise value is equal to or greater than the predetermined threshold value. If it is determined that the noise level is equal to or higher than the threshold value, the process proceeds to step S2j, and the presentation mode is selected as “text & video & audio” so as to present information regarding the projection target 27 in all presentation modes. To do. Also, in the determination of the noise value in step S2h, if the noise value is less than or equal to the threshold value, the presentation mode is selected as “speech”.

  On the other hand, in the determination of the illuminance value in step S2d, if the illuminance value is less than or equal to the threshold, the process proceeds to step S2e to determine whether or not the noise value is greater than or equal to the threshold. If it is determined that the noise value is equal to or greater than the threshold value, the process proceeds to step S2g and the presentation information is selected as “text & video”. If it is determined in step S2e that the noise value is equal to or lower than the threshold value, the process proceeds to step S2f and the presentation mode is selected as “highest priority selection”.

  The presentation mode selected in this way is input to the DB search unit 8, and the DB search unit 8 selects a file name according to the presentation mode input from the setting information DB 24 from the first presentation information selection table. The presentation information corresponding to the selected file name is read, and if it is text or video, it is output to the projector 6 by the display / processing control unit 7. If it is a voice, it is output to the output control unit 10 and is output loudly from the speaker 9.

  As described above, the information presentation apparatus 100 includes the information presentation unit 2 and the environmental condition detection unit 12, and the illuminance meter 11, the noise level meter 16, the projector 6, and the speaker 9 are connected to each other. Then, the determination unit 15 compares the measured value input from the illuminometer 11 and the sound level meter 16 with a predetermined threshold value, and presents a presentation information presentation mode (text, video, or audio data) according to the work site. Or a combination) is selected. The selected presentation mode is input to the DB search unit 8, and the DB search unit 8 acquires the presentation information associated with the projection object 27 from the setting information DB 24 according to the input presentation mode. Then, the information presentation unit 2 outputs the obtained presentation information to the work space by the projector 6 or the speaker 9.

  Therefore, according to 1st Embodiment, the information presentation apparatus 1 can detect the environmental condition of a work site, and can present the information regarding a work target in the suitable presentation mode according to the detected environment. It becomes. As a result, for example, in a bright place that is exposed to direct sunlight, information on the work object is output by voice. On the other hand, if the noise level at the work site is high, the work object is output by text or video. Information about the object is presented. For this reason, the remote instructor can easily and reliably transmit the work instruction to the field worker, and work efficiency can be improved.

  In the first embodiment, the illuminance meter 11 and the noise meter 16 are used to select the presentation mode for the illuminance value and the noise value measured from them. A vibration meter may be provided to select the presentation mode according to the vibration level. In this way, when vibration is large, it is possible to present work instructions and the like by voice.

(Second Embodiment)
FIG. 4 is a block diagram showing a remote operation support system provided with an information presentation device according to the second embodiment of the present invention. In this remote work support system, the information presentation device 100A, the information setting device 200, and the setting information DB 24A can be connected via a communication network NW. In the figure, the same parts as those in FIG.

  In the setting information DB 24A, similar to the first embodiment, the presentation information related to the work input by the remote instructor from the data input unit 22 of the information setting device 200 includes a plurality of presentation modes (text data, video data, and Audio data). In addition, the setting information DB 24A stores simplified presentation information for each presentation mode that includes only work instruction points and outlines, and a second presentation information selection table for selecting these presentation information. ing. FIG. 9 shows the configuration of the second presentation information selection table stored in the setting information DB 24A. In addition to the text file name, video file name, audio file name, and top priority selection file name for each projection object, the second presentation information selection table includes a simplified text file name and a simplified video image. It consists of a file name and a simplified audio file name.

  100 A of information presentation apparatuses are provided with the worker condition detection part 36 in addition to the information presentation part 2 and the environmental condition detection part 12A. The worker situation detection unit 36 includes a tag data acquisition unit 30, a tag data storage unit 31, an identification unit 32, a work time measurement unit 33, a work frequency measurement unit 34, and an identification table unit 35.

  By the way, an RFID tag (Radio Frequency IDentification) 28 is attached to each field worker. Each RFID tag 28 stores a unique worker identification ID, and the RFID tag 28 transmits a radio signal including the worker identification ID. On the other hand, the RFID reader 29 is connected to the information presentation apparatus 100A, receives the radio signal transmitted from the RFID tag 28, and recognizes the worker identification ID from the received radio signal. The tag data acquisition unit 30 acquires the recognized worker identification ID from the RFID reading unit 29 and stores it in the worker data storage unit 31.

  The identification table unit 35 stores a work history information table and a skill level identification table. The work history information table stores the work history of each worker, and stores the number of operations and the average work time in association with the worker identification ID. FIG. 11 shows an example of the configuration of the work history information table. As shown in FIG. 10, the skill level identification table includes a skill level ID, the number of operations, an average work time, and a type, and is used to identify the skill level based on the number of operations and the average work time.

  The identification unit 32 acquires the skill level ID of the worker from the worker identification ID stored in the worker data storage unit 31, the work history information table and the skill level identification table stored in the identification table unit 35. To do. The identification unit 32 inputs the acquired skill level ID of the worker to the determination unit 15A. Further, the work time measuring unit 33 measures the work time from the start time and the end time of the work by the worker. The work start time is the time when the presentation of information associated with the projection object 27 by the projector 6 or the speaker 9 is started, and the work end time is, for example, the remote instructor inputs the end time using the data input unit 22. Shall. An average work time is newly calculated from the measured work time and the average work time stored in the work history information table, and the calculated average work time is stored. When the end of work is detected, the work number measuring unit 34 counts up the number of work times in the worker history information table.

  On the other hand, in addition to the illuminance value acquired from the illuminance data storage unit 14 and the noise value acquired from the noise data storage unit 18, the determination unit 15A of the environmental condition detection unit 12A is further input from the identification unit 32. Based on the skill level ID of the operator, an optimum presentation mode is selected from text data, video data, audio data, simplified text data, simplified video data, and simplified audio data. Then, the determined presentation mode is output to the DB search unit 8.

  The operation of the information presentation apparatus 100A configured as described above will be described. FIG. 5 to FIG. 8 are flowcharts showing the processing procedure of the information presentation operation and the processing content in the information presentation apparatus 100A. Prior to this, it is assumed that the field worker has performed an operation of presenting information associated with the projection object 27 using the pointing tool 26.

  Then, in step S5a of FIG. 5, first, the worker status detection unit 36 of the information presentation apparatus 100A uses the tag data acquisition unit 30 to set the worker identification ID issued by the RFID tag 28 attached to the site worker to the RFID. The worker identification ID acquired from the reading unit 29 is stored in the worker data storage unit 31. In step S5b, the worker history information (the number of operations and the average work time) is acquired from the work history information table stored in the identification table unit 35 by the worker ID stored in the worker data storage unit 31. .

  Next, the identification unit 32 of the worker status detection unit 36 acquires the skill level ID of the worker by collating the acquired history information with the skill level identification table stored in the identification table unit 35 in step S5c. To do. That is, the skill level ID of the worker is determined as follows. First, the skill level ID of the worker is determined based on the AND condition of the acquired number of operations and average operation time. If this condition is not met, first, after searching for the corresponding skill level by the number of operations, it is determined whether the acquired average work time exceeds the average work time set for the searched skill level. To do. If it is determined that the average work time is exceeded, the skill level is lowered by one level. On the other hand, even if the average work time is equal to or less than the average work time set in the skill level, the skill level remains unchanged. For example, even if the skill level ID is “01 (intermediate worker)” in the number of operations, if the average work time exceeds the average work time of the beginner worker, the skill level is lowered by one step and the skill level ID is set to “ 00 (Beginner) ”.

  In addition, in step S5d, the environmental state detection unit 12A of the information presentation device 100A acquires an illuminance value and a noise value in the same procedure as in the first embodiment. Then, the determination unit 15A of the environmental state detection unit 12A selects the presentation mode of information associated with the projection object 27 as follows. First, in step S5e, determination based on the acquired skill level ID is performed.

  When it is determined that the skill level ID is “00 (beginner worker)”, the process proceeds to step S6a in FIG. 6 to determine the acquired illuminance value and a predetermined threshold value. If the illuminance value is smaller than the threshold value, the process proceeds to step S6b, and further the determination of the acquired noise value and the predetermined threshold value is performed. If these determinations indicate that both the illuminance value and the noise value are smaller than the respective threshold values, the process proceeds to step S6c to select “Video & Audio”. If it is determined in step S6b that the noise value is greater than or equal to the threshold value, the process proceeds to step S6d and “video” is selected.

  On the other hand, if it is determined in step S6a that the illuminance value is equal to or greater than the threshold value, the process proceeds to step S6e to determine the noise value and the predetermined threshold value. If it is determined that the noise value is smaller than the threshold value, the process proceeds to step S6f, and “speech (specified number of times)” for repeatedly outputting the sound data a predetermined number of times is selected. This specified number of times is preset when the remote instructor inputs presentation information from the information setting device 200, and is stored in the setting information DB 24A. If it is determined in step S6e that both the illuminance value and the noise value are equal to or greater than the respective threshold values, the process proceeds to step S6g, and “video & text & voice” presented in all presentation modes is selected.

  In step S6h, according to the presentation mode selected as described above, text and video data are output from the projector 6, and audio data is output from the speaker 9. In step S6i, the work time measuring unit 33 of the worker situation detecting unit 36 measures the work time from the start to the end of the presentation of the presentation information. In step S6j, the average work time is calculated based on the measured work time, and the average work time in the work history information table stored in the identification table unit 35 is updated with the calculated average work time. . In step S6k, the number of operations in the operation history information table is increased by 1.

Next, the case where the identification unit 32 identifies the skill level ID “01 (intermediate worker)” will be described. If it is determined in step S5e that the skill level ID is “01 (intermediate worker)”, the process proceeds to step S7a in FIG.
First, in step S7a of FIG. 7, the illuminance value and a predetermined threshold value are determined. When the illuminance value is smaller than the threshold value, the process proceeds to step S7b, and the acquired noise value and a predetermined threshold value are further determined. If these determinations indicate that both the illuminance value and the noise value are smaller than the respective threshold values, the process proceeds to step S7c to select “text & voice”. If it is determined in step S7b that the noise value is equal to or greater than the threshold value, the process proceeds to step S7d and “text” is selected.

  On the other hand, if it is determined in step S7a that the illuminance value is equal to or greater than the threshold value, the process proceeds to step S7e to determine the noise value and the predetermined threshold value. As a result of this determination, when the noise value is smaller than the threshold value, “sound” that repeatedly outputs the sound data a predetermined number of times is selected. If it is determined in step S7e that both the illuminance value and the noise value are equal to or greater than the respective threshold values, the process proceeds to step S7g to select “video & text & voice” to be presented in all presentation modes. Thus, after the presentation mode is selected on the condition of the skill level of the intermediate worker and the environmental condition (illuminance value and noise value), the processes of steps S6h to S6k in FIG. 6 are performed.

Finally, a case where the identification unit 32 identifies the skill level ID “02 (advanced worker)” will be described. If it is determined in step S5e that the skill level ID is “02 (advanced worker)”, the process proceeds to step S8a in FIG.
First, in step S8a of FIG. 8, the illuminance value and a predetermined threshold value are determined. When the illuminance value is smaller than the threshold value, the process proceeds to step S8b, and further the determination of the acquired noise value and the predetermined threshold value is performed. If both the illuminance value and the noise value are smaller than the respective threshold values as a result of these determinations, the process proceeds to step S8c to output “text (summary) & voice (summary)” for outputting simplified text data and simplified voice data. select. If it is determined in step S8b that the noise value is greater than or equal to the threshold value, the process proceeds to step S8d and “text (outline)” is selected.

  On the other hand, if it is determined in step S8a that the illuminance value is equal to or greater than the threshold value, the process proceeds to step S8e to determine the noise value and the predetermined threshold value. As a result of this determination, if the noise value is smaller than the threshold value, “sound (outline)” that repeatedly outputs the sound data a predetermined number of times is selected. If it is determined in step S8e that both the illuminance value and the noise value are equal to or greater than the respective threshold values, the process proceeds to step S8g, and “video & text & voice” to be presented in all presentation modes is selected. In this way, after the presentation mode is selected on the condition of the work skill level and the environmental situation (illuminance value and noise value) for the senior worker, the processing of steps S6h to S6k in FIG. 6 is performed.

  As described above, the information presentation apparatus 100A according to the second embodiment further includes the worker situation detection unit 36. The worker status detection unit 36 identifies the worker from the RFID tag attached to the worker, and reads the work history information of the worker identified from the identification table unit 35. Further, the work skill level is acquired from the read work history information. In addition, the environmental condition detection unit 12A acquires the illuminance value and the noise value as in the first embodiment. The determination unit 15A selects a presentation mode suitable for the situation on the condition of the acquired work skill level of the worker, an illuminance value, and a noise value, and the projection object 27 is selected in the selected presentation mode. The information associated with is presented.

  Since it is such a structure, since the said information presenter only attaches a wireless tag and attribute information is acquired from this wireless tag, the effort and time which input attribute information can be saved.

(Third embodiment)
FIG. 12 is a block diagram showing a remote operation support system including an information presentation device according to the third embodiment of the present invention. In this remote work support system, the information presentation device 100B, the information setting device 200, and the setting information setting information DB 24A can be connected via a communication network NW. In the figure, the same parts as those in FIG. 4 in the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The information presentation device 100B includes an audio processing unit 42 in addition to the information presentation unit 2 and the environmental condition detection unit 12B, and a microphone 37 is connected to the information presentation device 100B. The site worker instructs the presentation mode of information associated with the projection object 27 by voice. The microphone 37 collects the emitted voice, and the collected voice is input to the voice receiving unit 38.

  The voice processing unit 42 includes a voice receiving unit 38, a voice recognition unit 39, a recognition result storage unit 40, and a voice command database (voice command DB) 41. The voice receiving unit 38 digitally converts the voice of the field worker inputted from the microphone 37 and then inputs the voice data to the voice recognition unit 39 as voice data. In the voice command DB 41, voice commands (for example, “text mode”, “video mode”, “voice mode”) representing each presentation mode are stored in advance. The voice recognition unit 39 compares the input voice data with a voice command representing the presentation mode stored in the voice command DB 41, recognizes the presentation mode instructed by the field worker, and the recognition result. Is stored in the recognition result storage unit 40.

  The operation of the information presentation apparatus 100B configured as described above will be described. FIG. 13 to FIG. 16 are flowcharts showing the processing procedure of the information presentation operation and the processing content in the information presentation device 100B. Prior to this, it is assumed that the field worker performs an operation of presenting information associated with the projection object 27 by using the pointing tool 26 and instructs a presentation mode for presenting this information by voice.

  Then, in step S13a of FIG. 13, first, the voice processing unit 42 of the information presentation apparatus 100B accepts the presentation mode designated by the voice from the microphone 37 by the voice reception unit 38 by the field worker. The received voice is digitally converted by the voice receiver 38 and input to the voice recognizer 39 as voice data. The voice recognition unit 39 compares the voice data of each presentation mode stored in the voice command DB 41 with the voice data, and stores the recognized presentation mode in the recognition result storage unit 40.

  Next, in step S13b, the worker status detection unit 36 of the information presentation device 100B obtains a worker identification ID in the same procedure as in the second embodiment, using the RFID tag 28 attached to the site worker. To do. In step S13c, the illuminance value and the noise value are acquired in the same procedure as in the first embodiment. And the determination part 15B of the environmental condition detection part 12B selects the presentation mode of the information linked | related with the projection target object 27 as follows. First, in step S13d, determination based on the recognized presentation mode is performed.

  When it is determined that the presentation mode is “text mode”, the process proceeds to step S14a in FIG. 14 to determine the acquired illuminance value and a predetermined threshold value. When the illuminance value is smaller than the threshold value, the process proceeds to step S14b, and the determination based on the acquired skill level ID is performed. If it is determined by this determination that the skill level ID is “00 (beginner worker)” or “01 (intermediate worker)”, the process proceeds to step S14c and “text” is selected. If it is determined in step S14b that the skill level ID is “02 (advanced worker)”, the process proceeds to step S14d and “text (outline)” is selected.

  On the other hand, if it is determined in step S14a that the illuminance value is equal to or greater than the threshold value, the process proceeds to step S14e to determine the acquired noise value and the predetermined threshold value. In this determination, if the noise value is smaller than the threshold value, the process proceeds to step S14f, and determination based on the skill level ID is performed. If the skill level ID is “00 (beginner)” as a result of the determination in step S14f, the process proceeds to step S14g, and “speech (specified number)” for repeatedly outputting the sound data a predetermined number of times is selected. Is done. In the case of “01 (intermediate worker)”, “voice” is selected in step S14h. If it is determined in step S14f that the skill level ID is “02 (advanced worker)”, “voice (outline)” is selected in step S14i.

  If it is determined in step S14e that both the illuminance value and the noise value are equal to or greater than the respective threshold values, the process proceeds to step S14j, and “video & text & voice” to be presented in all presentation modes is selected. As described above, after the presentation mode is selected for the “text mode” on the condition of the work skill level and the environmental situation (illuminance value and noise value), the processing of steps S6h to S6k in FIG. 6 is performed.

Next, a case where the presentation mode is recognized as “video mode” will be described. If it is determined in step S13d that the presentation mode is “video mode”, the process proceeds to step S15a in FIG.
First, in step S15a in FIG. 15, the illuminance value and a predetermined threshold value are determined. When the illuminance value is smaller than the threshold value, the process proceeds to step S15b, and determination based on the skill level ID is performed. If it is determined by this determination that the skill level ID is “00 (beginner worker)” or “01 (intermediate worker)”, the process proceeds to step S15c to select “video”. If it is determined in step S15b that the skill level ID is “02 (advanced worker)”, the process proceeds to step S15d and “video (outline)” is selected.

  On the other hand, if it is determined in step S15a that the illuminance value is equal to or greater than the threshold value, the process proceeds to step S15e to determine the acquired noise value and the predetermined threshold value. In this determination, when the noise value is smaller than the threshold value, the process proceeds to step S15f, and determination based on the skill level ID is performed. If it is determined in step S15f that the skill level ID is “00 (beginner worker)”, the process proceeds to step S15g and “voice (specified number of times)” is selected. In the case of “01 (intermediate worker)”, “voice” is selected in step S15h. If it is determined in step S15f that the skill level ID is “02 (advanced worker)”, “voice (outline)” is selected in step S15i.

  If it is determined in step S15e that both the illuminance value and the noise value are equal to or greater than the respective threshold values, the process proceeds to step S15j, and “video & text & voice” to be presented in all presentation modes is selected. As described above, after the presentation mode is selected for the “video mode” on the condition of the work skill level and the environmental situation (illuminance value and noise value), the processing of steps S6h to S6k in FIG. 6 is performed.

Finally, a case where the presentation mode is recognized as the “voice mode” will be described. If it is determined in step S13d that the presentation mode is “voice mode”, the process proceeds to step S16a in FIG.
First, in step S16a of FIG. 16, the noise value and a predetermined threshold value are determined. When the noise value is smaller than the threshold value, the process proceeds to step S16b, and determination based on the skill level ID is performed. As a result of this determination, if the skill level ID is “00 (beginner worker)”, the process proceeds to step S16c, where “voice (specified number of times)” is selected. In the case of “01 (intermediate worker)”, “voice” is selected in step S16d. If it is determined in step S16f that the skill level ID is “02 (advanced worker)”, “voice (outline)” is selected in step S16e.

  On the other hand, if it is determined in step S16a that the noise value is equal to or greater than the threshold value, the process proceeds to step S16f to determine the acquired illuminance value and a predetermined threshold value. In this determination, when the illuminance value is smaller than the threshold value, the process proceeds to step S16g, and determination based on the skill level ID is performed. If it is determined in step S16g that the skill level ID is “00 (beginner worker)”, the process proceeds to step S16h and “video” is selected. In the case of “01 (intermediate worker)”, “text” is selected in step S16i. If it is determined in step S16f that the skill level ID is “02 (advanced worker)”, “text (outline)” is selected in step S16j.

  If it is determined in step S16f that both the illuminance value and the noise value are equal to or greater than the respective threshold values, the process proceeds to step S16k, and “video & text & voice” presented in all presentation modes is selected. In this way, after the presentation mode is selected for the “voice mode” on the condition of the work skill level and the environmental situation (illuminance value and noise value), the processing of steps S6h to S6k in FIG. 6 is performed.

  As described above, the information presentation apparatus 100B according to the third embodiment further includes the audio processing unit 42. The voice processing unit 42 recognizes the presentation mode by comparing the voice data including the presentation mode designated by the field worker with the voice command representing each presentation mode stored in the voice command DB 41. Moreover, the environmental condition detection part 12B acquires a worker's skill level ID, an illuminance value, and a noise value as in the second embodiment.
