Further, the present invention can obtain various effects including secondary effects obtained by the basic configuration and control.

  FIG. 1 is a diagram illustrating an example of a use state of the work content confirmation device 1. When the worker performs an operation of moving an article (not shown) from the first place to the second place, the work content confirmation device 1 outputs the work content by display or voice. The article is a thing that can be transported using a hand (human body) or a tool (machine operated by a worker) or the like, and is, for example, a part, a product for sale, a conveyed product, or the like. The first place and the second place are places different from each other, and are, for example, shelves, containers, trays, boxes, sections, collection sites, and the like. The output or presented work content may be a work instruction. The work content confirmation device 1 can also be called a work instruction device.

  The work content confirmation device 1 outputs a question about the work content by display or voice for each work. The work content confirmation device 1 can prompt input of an answer to the question. The work content confirmation device 1 has a function of inputting the answer by an operation of the worker. Further, the work content confirmation device 1 determines whether the answer is correct or not, and outputs the result of the determination, that is, the result according to the correctness of the answer, by display or voice. Specifically, for example, when the answer is a correct answer, the work content confirmation device 1 outputs an output indicating that the answer is correct, and outputs the next work content. On the other hand, if the answer is a wrong answer, the work content confirmation device 1 outputs a display or a voice to indicate that the answer is wrong, and prompts the user to redo the current work content. The work content confirmation device 1 can also be called a work support device.

  In the example of FIG. 1, the work content confirmation device 1 is held by a worker's hand H via a holder 100. The holder 100 includes an accommodating portion 101 that accommodates the work content confirmation device 1 and a belt portion (not shown). The holder 100 is detachably attached to an operator's hand H by a belt portion. The accommodation section 101 is provided with a rectangular opening 101 a, and the opening 101 a is covered with a transparent cover 102. The work content confirmation device 1 has a display screen 30a, a touch panel 20a that covers the display screen 30a, and operation buttons 20b. In a state where the work content confirmation device 1 is housed in the housing unit 101, the worker can visually recognize the display screen 30a via the cover 102. In addition, the operator can operate the touch panel 20a and the operation buttons 20b via the cover 102 with a finger or a stylus or the like. The work content confirmation device 1 acquires data (input data) corresponding to an input operation of the touch panel 20a or the operation button 20b.

  The work content confirmation device 1 is, for example, an electronic device such as a smartphone or a PDA (personal digital assistant). The electronic device functions as the work content confirmation device 1 by operating according to the installed programs (applications and software). The work content confirmation device 1 may be a dedicated device.

  FIG. 2 is a block diagram illustrating an example of a schematic configuration of the work content confirmation device 1. In the example of FIG. 2, the work content confirmation device 1 includes a control unit 10, an input unit 20, an output unit 30, a storage unit 40, and a communication unit 50.

  The control unit 10 is, for example, a CPU (central processing unit). The control unit 10 operates according to a program stored (installed) in the storage unit 40 and read at the time of operation. By operating according to the program, the control unit 10 functions as an instruction output control unit 10a, a question creation unit 10b, a question output control unit 10c, an input control unit 10d, a determination unit 10e, and a result output control unit 10f. The program includes modules corresponding to the instruction output control unit 10a, the question creation unit 10b, the question output control unit 10c, the input control unit 10d, the determination unit 10e, and the result output control unit 10f. Note that at least a part of the control unit 10 may be configured by hardware. In that case, the control unit 10 may include an ASIC (application specific integrated circuit), an FPGA (field programmable gate array), a CPLD (complex programmable logic device), and the like.

  The input unit 20 may be, for example, a microphone (not shown) in addition to the touch panel 20a and the operation buttons 20b as shown in FIG. The input unit 20 may be a key capable of inputting numbers and characters, a keypad, a keyboard, or the like. The input controller 21 controls the input unit 20. Data (input data) input at the input unit 20 is sent to the control unit 10 via the input controller 21. The input controller 21 can also be called an input control unit.

  The output unit 30 is, for example, a display having a display screen 30a as shown in FIG. 1, a speaker (not shown), or the like. The output controller 31 controls the output unit 30. The control unit 10 controls the output unit 30 via the output controller 31 so that predetermined data (output data) is output. The output controller 31 can also be called an output control unit.

  The communication unit 50 is, for example, an antenna. The communication controller 51 controls transmission and reception of signals between the communication unit 50 and external devices. The communication controller 51 acquires superimposed data (received data) from the signal received by the communication unit 50 and sends the data to the control unit 10. Further, the communication controller 51 superimposes data (transmission data) acquired from the control unit 10 on a signal, and transmits the signal via the communication unit 50. The communication controller 51 can also be called a communication control unit.

  The storage unit 40 is, for example, a nonvolatile rewritable storage unit such as a hard disk drive (HDD) or a flash memory. The storage controller 41 controls reading or writing of data in the storage unit 40. Further, the storage controller 41 reads out the data stored in the storage unit 40 and sends the data to the control unit 10. Further, the storage controller 41 writes the data received from the control unit 10 into the storage unit 40.

  The storage unit 40 includes input / output control reference data 40a, question creation reference data 40b, work data 40c, history data 40d, and the like. The input / output control reference data 40a is data that the control unit 10 refers to when controlling input or output. The question creation reference data 40b is data that the control unit 10 refers to when creating a question. The work data 40c is data indicating the contents of one or more works. The history data 40d is data indicating the history of work contents, questions, and answers. The control unit 10 adds new data and updates the history data 40d every time a task, a question, or an answer is made.

  The work content confirmation device 1 has a read only memory (ROM), a random access memory (RAM), and the like (both are not shown). Some of the input / output control reference data 40a, the question creation reference data 40b, and the work data 40c may be stored in the ROM. Further, a part of the input / output control reference data 40a, the question preparation reference data 40b, the work data 40c, the history data 40d, and the like may be included in the program, or the communication unit 50, the input unit 20, and the like. The information may be input to the work content confirmation device 1 through the storage unit 40 and stored in the storage unit 40.

  FIG. 3 is a flowchart illustrating a procedure of the arithmetic processing by the control unit 10. First, the control unit 10 functions as the instruction output control unit 10a, and acquires the work data 40c from the storage unit 40 (S1). Next, the control unit 10 functions as the instruction output control unit 10a, and controls the output controller 31 and thus the output unit 30 so that the instruction information corresponding to the work data 40c acquired in S1 is output (S2). In the present embodiment, a case where the instruction information is output for the work data 40c of one work to be performed next in S2 is exemplified. However, the present invention is not limited to this. Instruction information may be output for a plurality of operations to be performed. The output controller 31 and the instruction output control unit 10a are examples of a first output control unit.

  The instruction information is information indicating the content of the work to be performed by the worker, and includes various items in the work, for example, the articles to be moved, the number of articles to be moved, and the location of the articles (the source, The first place), the place to move the goods by the work (destination, the second place), the worker who performs the work, the time and order of performing the work, the work method, tools and devices used in the work, etc. It is information to be shown. The instruction information is indicated by characters or numbers, and may be an identifier, an identification number, or the like. The instruction information may be referred to as work content information.

  FIG. 4 is a front view of the work content confirmation device 1. FIG. 4 shows an example of the instruction information Imi for one work displayed on the display screen 30a of the work content confirmation device 1. The instruction information Imi includes "article number" which is information indicating an article, a place where the article is located, that is, a "shelf" indicating the first place, and a section in the container where the article is moved by work, that is, a second place. “Serving” and “number” of moving articles are included.

  Next, the control unit 10 functions as the question creation unit 10b, creates a question about the content of the work to be performed, and determines the output mode based on the acquired work data 40c (S3). The question is a question about the content (item) of the work to be performed based on the instruction information. For example, the article to be moved, the number of articles to be moved, the place where the article is located (source of movement, first Question) about the location of the goods), the place where the goods are moved by the work (the destination, the second place), the worker who performs the work, the time and order of the work, the work method, tools and devices used in the work, etc. It is. The output mode is a mode of outputting the question in the output unit 30, and is, for example, a position, a size, an order, and the like for outputting the question to the output unit 30. When the question includes an option, the question may include only the option, a word indicating the content of the question, a word prompting an answer, or the like.

  Next, the control unit 10 functions as the input control unit 10d, and waits for an input indicating the end of the work, that is, an input indicating that the work by the worker has been completed (S4). At S4, the control unit 10 controls the output controller 31 and the output unit 30 so that the input area image Imp indicating the input area corresponding to the end of the work is output to the display screen 30a as shown in FIG. ing. In the example of FIG. 4, the input area image Imp is a button displayed as “Picking completed”.

  After S4, the control unit 10 determines whether an end condition (first end condition) is satisfied (S5). In S5, for example, the control unit 10 compares the elapsed time from the start of the standby state in S4 with a first threshold time (for example, several hours), and the elapsed time exceeds the first threshold time. In this case (Yes in S5), the flow of FIG. 3 ends. In this case, the termination condition (first termination condition) is that the elapsed time from the start of the standby state in S4 exceeds the first threshold time.

  If No in S5, that is, if the termination condition is not satisfied, the control unit 10 functions as the input control unit 10d, and determines whether an input indicating the end of the work has been input (S6). In the example of FIG. 4, the area of the touch panel 20a that overlaps the input area image Imp is the input area. Therefore, in S6, the input control unit 10d determines whether or not there is an input indicating the end of the work, that is, whether or not there is an input operation such as a contact or a press in the input area overlapping the input area image Imp. If there is an input indicating the end of the work (Yes in S6), the process proceeds to S7, and if there is no input indicating the end of the work (No in S6), the process proceeds to S5.

  FIG. 5 is a front view of the work content confirmation device 1 and shows a state where an image different from that of FIG. 4 is displayed. When there is an input indicating the end of the work (Yes in S6), the control unit 10 functions as a question output control unit 10c, and, for example, as shown in FIG. 5, deletes the content of the question determined by the question creation unit 10b in S3. , S3, the output controller 31 and thus the output unit 30 are controlled so as to output in the mode determined by the question creating unit 10b (S7). The question output control unit 10c and the output controller 31 are examples of a second output control unit.

  FIG. 5 shows an example of the question information Imq about one work output on the display screen 30a of the work content confirmation device 1 in S7. In the example of FIG. 5, the option image Ims of the question “number” of the moving articles is output as the question information Imq. The option image Ims includes an option image Ims of one correct answer R and an option image Ims of a plurality of incorrect answers F. In the example of FIG. 5, four display areas (display positions P1 to P4) for displaying the option image Ims on the display screen 30a are set. In the case of FIG. 5, in S3, the control unit 10 functions as the question creating unit 10b and outputs the option images Ims (in this case, the correct answer R is “5”, and the incorrect answers F are “7” and “4”). , And "2") and the display positions P1 to P4 of the option images Ims. The control unit 10 functions as the question output control unit 10c in S7, and the output controller 31 and the output unit 30 so that the option image Ims determined in S3 is displayed at the display positions P1 to P4 determined in S3. Control. The question creating unit 10b is an example of a display position determining unit. In addition, the question creating unit 10b may be referred to as an output mode determining unit.

  Regarding the question output in S7 of FIG. 3, the question creating unit 10b can determine an incorrect answer F (options) by using the following methods (1) to (8) alone or in combination in S3. The question creator 10b sets one or more alternatives of the wrong answer F different from the correct answer R, and sets a plurality of alternatives of the wrong answer F when setting a plurality of alternatives of the wrong answer F. Set.

  (1) The question creating unit 10b can randomly select an option of the incorrect answer F from a plurality of candidates for the incorrect answer F. In the example of FIG. 5, for example, the question creating unit 10b uses a random number from among a plurality of numerical values (candidates and integers equal to or more than 1) excluding “5” as the correct answer R, and selects the incorrect answer F as an option. , “7”, “4”, and “2”.

  (2) The question creating unit 10b can select an option of the incorrect answer F from a numerical value range of candidates set corresponding to the correct answer R. For example, consider a case where the numerical value range of the option of the incorrect answer F is set to “1” or more and “9” or less, corresponding to the correct answer R that is “1” or more and “9” or less. In this case, for example, when the correct answer R is “5”, the question creating unit 10b selects candidates (“1” or more and “9” or less and included in the numerical range excluding “5” of the correct answer R). Integer of 1 or more), that is, the choice of wrong answer F from among “1”, “2”, “3”, “4”, “6”, “7”, “8”, and “9” can do. Therefore, the question creating unit 10b can relatively easily set the option of the incorrect answer F.

  (3) When the answer is a numerical value, the numerical range of the option candidate of the incorrect answer F can be variably set according to the numerical value of the correct answer R. For example, when the correct answer R is equal to or more than "1" and equal to or less than "9", the numerical value range of the candidates for the incorrect answer F is set to "1" or more and "9" or less (excluding the correct answer R), When the correct answer R is equal to or more than "10" and equal to or less than "19", the numerical range of the option candidates of the incorrect answer F may be set to "10" or more and "30" or less (excluding the correct answer R). . As described above, the smaller the correct answer R, the narrower the numerical value range of the candidate for the incorrect answer F, and the larger the correct answer R, the wider the numerical range of the candidate for the wrong answer F. The question creating unit 10b selects the option of the incorrect answer F from the numerical range of the candidate of the incorrect answer F. If the value of the option of the incorrect answer F deviates from the value of the correct answer R, the correct answer R becomes easier to understand, that is, the difficulty level of the question decreases, and the effect of setting the question may be reduced. In this regard, according to the present embodiment, since the option of the incorrect answer F is selected from a numerical range relatively close to the correct answer R, it is possible to prevent the difficulty of setting the question from being reduced and the effect of setting the question from weakening. sell.

  (4) The question creating unit 10b can include the correct answer R in the question of another work in the past in the option of the incorrect answer F. For example, the question creating unit 10b refers to the past work data 40c, and, in the past work, corrects the correct answer R (but not the correct answer R of the question of the current work) in the same type of question item in the past work. Can be adopted as an option. Specifically, for example, the correct answer R of the question of the number of moving articles in the current work is “2”, and the same question in the past work, that is, the correct answer R of the number of moving articles is “3”. In this case, “3” can be adopted as an option of the incorrect answer F to the question of the number of moving articles in the current work. In addition, the question creating unit 10b adopts the correct answer R in the same kind of question item as an option of the incorrect answer F in a relatively close past work, for example, in the work from the previous one to five times (predetermined times). Can be.

  (5) The question creator 10b sets, as an option of the incorrect answer F, the frequency at which the correct answer R in a plurality of past work questions among the correct answers R in the past different work questions is a first threshold (predetermined value). Higher than the threshold value of the threshold value). For example, the question creating unit 10b refers to the past work data 40c and finds the correct answer R (but not the correct answer R of the question of the current work) in the same type of question item in a predetermined number of works in the past. Of the values (candidates), a value (candidate) having a frequency of correct answers R at a predetermined number of times higher than a first threshold (for example, 30%) can be adopted as an option of the incorrect answer F this time. Specifically, for example, the correct answer R of the question of the number of moving articles in the current work is “2”, and the same question in the past work, that is, the correct answer R of the number of moving articles, is “3” and “ "4", "3" is the correct answer R twice in the past five operations (that is, the frequency is 40%), and "4" is the correct answer R once in the past five operations (that is, the frequency). 20%), the frequency at which “3” was the correct answer R in the past five operations is higher than the first threshold value of 30%, and the frequency at which “4” was the correct answer R is the first threshold. Lower than the threshold value of 30%. In this case, the question creating unit 10b can adopt “3” as an option of the incorrect answer F to the question of the number of moving articles in the current work.

  (6) The question preparing unit 10b sets the frequency of the correct answer R in a plurality of past work questions to another value (candidate) among the correct answers R in the past different work questions among the alternatives of the incorrect answer F. Higher ones can be included. For example, the question creating unit 10b refers to the past work data 40c and finds the correct answer R (but not the correct answer R of the question of the current work) in the same type of question item in a predetermined number of works in the past. Of the plurality of values (candidates), the one that has a higher frequency of correct answers R in a predetermined number of times than other values (candidates) can be adopted as an option of the incorrect answer F this time. Specifically, for example, the correct answer R of the question of the number of moving articles in the current work is “2”, and the same question in the past work, that is, the correct answer R of the number of moving articles, is “3” and “ "4", "3" is the correct answer R twice in the past five operations (that is, the frequency is 40%), and "4" is the correct answer R once in the past five operations (that is, the frequency). 20%), the frequency at which “3” was the correct answer R in the past five operations is higher than the frequency at which “4” was the correct answer R. In this case, the question creating unit 10b can adopt “3” as an option of the incorrect answer F to the question of the number of moving articles in the current work.

  (7) The question creator 10b may include, in the options of the incorrect answer F, among the answers to the questions of the other work in the past, those having the input frequency higher than the second threshold (predetermined threshold). it can. For example, the question creating unit 10b refers to the past history data 40d and, in a predetermined number of past works, answers to questions of the same kind (but not the correct answer R of the question of the current work). Of the values (candidates), the value (candidate) whose frequency input at a predetermined number of times is higher than a second threshold value (for example, 30%) can be adopted as an option of the incorrect answer F this time. Specifically, for example, the correct answer R of the question of the number of moving articles in the current work is “2”, and the same question in the past work, that is, “3” as the answer of the question of the number of moving articles and “4” has been input, “3” has been input as a response twice in the past five operations (ie, frequency of 40%), and “4” has been input as a single response in the past five operations. In the case where the frequency is “20%”, the frequency at which “3” is input as an answer in the past five operations is higher than the second threshold value of 30%, and the frequency at which “4” is input as an answer. Is lower than the second threshold of 30%. In this case, the question creating unit 10b can adopt “3” as an option of the incorrect answer F to the question of the number of moving articles in the current work.

  (8) The question creator 10b can include, in the choices of the incorrect answer F, those in which the frequency of input (selection) as an answer in a past question of another work is higher than other values (candidates). . For example, the question creating unit 10b refers to the history data 40d, and in a predetermined number of past operations, among a plurality of values (candidates) input as answers in the same type of question item, the answer is input as a predetermined number of times. Those with a higher frequency than other values (candidates) can be adopted as alternatives for the incorrect answer F this time. Specifically, for example, the correct answer R of the question of the number of moving articles in the current work is “2”, and the same question in the past work, that is, “3” and “4” as the answers of the number of moving articles. "Has been input," 3 "has been input as a response twice in the past five operations (i.e., a frequency of 40%), and" 4 "has been input as a single response in the past five operations (i.e., in the past five operations). In this case, the frequency of inputting "3" as a response in the past five operations is higher than the frequency of inputting "4" as a response. In this case, the question creating unit 10b can adopt “3” as an option of the incorrect answer F to the question of the number of moving articles in the current work.

  In the above (1) to (8), the case where the option (answer) is an integer of 1 or more is illustrated, but the answer is not limited to this, and may be a numerical value other than an integer. It may be other than a numerical value. Options other than numerical values include, for example, characters, images, and the like. The options may include a question (item), a number (identification number) for identifying each option, characters, abbreviations, symbols, images, colors, patterns, and the like. When the option is not a numerical value, the question creating unit 10b assigns a numerical value (for example, an integer) to each of the plurality of options, and calculates the incorrect answer F by the same arithmetic processing as the above (1) to (8). Can be determined.

  Regarding the question output in S7 of FIG. 3, the question creating unit 10b can determine the output mode of the correct answer R and the incorrect answer F (options) in S3. For example, when the output unit 30 is a display (display output unit), the question creating unit 10b determines the number (four in the example of FIG. 5) and the display position (four in the example of FIG. 5) of the option images Ims for a plurality of questions. P1 to P4) are set to the same (common). In addition, the question creating unit 10b performs the display so that the display position of the option image Ims of the correct answer R (and the incorrect answer F) at the common display position (P1 to P4) for a plurality of questions changes randomly for each question. Determine the position. In this case, for example, the question creating unit 10b randomly selects a numerical value from random numbers (for example, 1 to 4) assigned to a plurality of display positions (P1 to P4) using random numbers, and determines the order of the numerical values. By doing so, the display position of the option image Ims of the correct answer R (and the incorrect answer F) can be determined. When the output unit 30 is a speaker (voice output unit), the question creating unit 10b sets the number of options for a plurality of questions to be the same (common) and outputs the options of the correct answer R by voice, for example. Can be changed randomly.

  After S7 in FIG. 3, the control unit 10 functions as the input control unit 10d, and waits for input of an answer by the operator (S8). At S8, the control unit 10 controls the output controller 31 and the output unit 30 so that the option image Ims of the correct answer R and the incorrect answer F is output to the display screen 30a as shown in FIG. In the example of FIG. 5, the option image Ims is a button labeled “5” as the correct answer R and “7”, “4”, and “2” as the incorrect answers F.

  After S8, the control unit 10 determines whether the termination condition is satisfied (S9). In S9, for example, the control unit 10 compares the elapsed time from the start of the standby state in S8 with a second threshold time, and when the elapsed time exceeds the second threshold time (Yes in S9). , The flow of FIG. In this case, the termination condition is that the elapsed time from the start of the standby state in S8 exceeds the second threshold time.

  If No in S9, that is, if the termination condition is not satisfied, the control unit 10 functions as the input control unit 10d and determines whether or not an input indicating an answer has been input (S10). In the example of FIG. 5, an area of the touch panel 20a overlapping the option image Ims is an input area. In this case, in S10, the input control unit 10d determines the presence or absence of an input indicating an answer, that is, the presence or absence of an operation in an input area overlapping the option image Ims. When there is an input indicating an answer (Yes in S10), the process proceeds to S11, and when there is no input indicating an answer (No in S10), the process proceeds to S9.

  When an answer is input (Yes in S10), the control unit 10 functions as the determination unit 10e, and determines whether the answer is correct, that is, in the example of FIG. It is determined whether an input area overlapping with Ims has been operated (S11). Specifically, the determination unit 10e determines whether the input data is data corresponding to a correct answer.

  As a result of the determination in S11 by the determination unit 10e, when the answer is correct, that is, in the example of FIG. 5, the operator has operated the input area overlapping the option image Ims corresponding to the correct answer R (that is, "5"). In this case (Yes in S12), the control unit 10 functions as the result output control unit 10f, and controls the output controller 31 and, consequently, the output unit 30 so that the output according to the correct answer, that is, the output at the time of the correct answer is performed (S13). . Specifically, the result output control unit 10f outputs an output controller 30 such that, for example, a correct answer notification image (not shown) in the form of a character string “work was performed correctly” is output on the display screen 30a. The control unit 31 controls the output unit 30.

  After S13, the control unit 10 determines whether the scheduled work has been completed (S15). When all the scheduled work is completed (Yes in S15), the flow in FIG. 3 ends. On the other hand, if all scheduled work has not been completed (No in S15), the process proceeds to S1 for the next work. That is, the control unit 10 executes the procedures of S1 to S15 for the next work.

  FIG. 6 is a front view of the work content confirmation device 1 and shows a state where an image different from those in FIGS. 4 and 5 is displayed. As a result of the determination in S11 by the determination unit 10e, if the answer is incorrect, that is, in the example of FIG. 5, the operator responds to the incorrect answer F (that is, "7", "4", or "2"). When the input area overlapping with the option image Ims is operated (No in S12), the control unit 10 functions as the result output control unit 10f, and performs an output according to an incorrect answer, that is, an output at the time of an incorrect answer. The output controller 31 and thus the output unit 30 are controlled (S14). Specifically, for example, as shown in FIG. 6, the result output control unit 10f outputs the wrong answer notification image Imr in the form of “the number is different” on the display screen 30a. , The output controller 31 and the output unit 30. After S14, the same operation as before proceeds to S2.

  FIG. 7 is a front view showing a work content confirmation device 1A according to a modification. The work content confirmation device 1A has the same function as the work content confirmation device 1 and can operate in the same manner. However, the work content confirmation device 1A has two display screens 30a and 30b (output unit 30, see FIG. 2). The question information Imq is displayed on the display screen 30b, and the option image Ims and the input area image Imp are displayed on the display screen 30a. In this case, the option image Ims may be a plurality of pseudo buttons displayed on the display screen 30a, or may be displayed for each of a plurality of (four in the example of FIG. 7) input buttons as hardware. Is also good. The work content confirmation device 1A may include a body having the display screen 30a and a body having the display screen 30b.

  As described above, in the work content confirmation devices 1 and 1A, the question creation unit 10b creates a question of the work content based on the work data 40c, and outputs the question output control unit 10c and the output controller 31 (second controller). An output control unit) controls the output unit 30 so that the question is output. The determination unit 10e determines whether the data input by the input unit 20 is data corresponding to a correct answer to the question, and the result output control unit 10f and the output controller 31 (third output control unit) The output unit 30 is controlled so that a result is output based on the determination result. Therefore, according to the work content confirmation devices 1 and 1A of the present embodiment, for example, the worker can confirm the content of the performed work, so that the reliability of the work of moving the article can be improved. In addition, for example, since a worker is given an answer to a question about the work content in addition to performing the work, a decrease in the concentration of the worker can be suppressed, and the reliability of the work can be improved.

  Further, in the work content confirmation devices 1 and 1A, the question creating unit 10b creates a question including alternatives of the correct answer R and the incorrect answer F. Therefore, for example, an operator can answer a question by a simpler operation than in a case where an answer is directly input.

  In the work content confirmation devices 1 and 1A, the question creating unit 10b (display position determining unit) displays the choice image Ims at a plurality of display positions P1 to P4 common to a plurality of questions set on the display screen 30a. Thus, the display positions P1 to P4 of the option image Ims are determined. Therefore, for example, the operator can easily input the answer as compared with the case where the display positions P1 to P4 of the option image Ims change for each question.

  In the work content confirmation devices 1 and 1A, the question creating unit 10b (display position determining unit) determines whether the display position (any one of P1 to P4) where the option image Ims of the correct answer R is displayed is random for a plurality of questions. Is determined, the display position of the option image Ims is determined. Therefore, for example, the operator cannot easily select the correct answer R as compared with the case where the options of the correct answer R are displayed at the same display position. Therefore, the concentration of the worker can be prevented from being reduced.

  In the work content confirmation devices 1 and 1A, when the answer to the question is correct, the instruction output control unit 10a and the output controller 31 (first output control unit) perform the next work (second work). The output unit 30 is controlled so that the content is output. If the answer to the question is incorrect, the question output control unit 10c and the output controller 31 (second output control unit) The output unit 30 is controlled so as to output the question about the operation (1). Therefore, for example, it is suppressed that the next operation is performed when the current operation content is incorrect.

  In the work content confirmation devices 1 and 1A, the question creating unit 10b can randomly select an option of the incorrect answer F from a plurality of candidates for the incorrect answer F. Therefore, for example, a situation where only specific options are fixedly set for a plurality of questions can be avoided, and the options can be automatically set relatively easily.

  Further, in the work content confirmation devices 1 and 1A, the question creating unit 10b can select an option of the incorrect answer F from a numerical range of candidates set corresponding to the correct answer R. Therefore, the question creating unit 10b can relatively easily set, for example, the option of the incorrect answer F.

  Further, in the work content confirmation devices 1 and 1A, the numerical range of the option candidates of the incorrect answer F can be variably set according to the numerical value of the correct answer R. Therefore, for example, since the option of the incorrect answer F is selected from a numerical range relatively close to the correct answer R, it is possible to suppress a decrease in the difficulty of the question and a decrease in the effect of setting the question.

  Further, in the work content confirmation devices 1 and 1A, the question creating unit 10b can include, among the correct answers R in the past questions, those whose frequency of being the correct answer R is equal to or more than the first threshold. In addition, the question creating unit 10b can include, among the plurality of alternatives of the incorrect answer F, a candidate whose frequency of being the correct answer R in the past question is higher than other candidates among the plurality of alternatives of the incorrect answer F. . In addition, the question creating unit 10b can include, in the choices of the incorrect answer F, an answer to the past question whose input frequency is equal to or more than the second threshold. In addition, the question creating unit 10b can include, in the options of the incorrect answer F, a plurality of options of the incorrect answer F that have a higher frequency of being selected as an answer in the past question than other candidates. . Therefore, for example, the operator can easily select the incorrect answer F as an answer, and the difficulty of the question is prevented from lowering. Therefore, the effect of setting the question can be suppressed from being reduced.
