FIG. 1 is a diagram illustrating an example of a system configuration of an information processing system.
The information processing system includes a smart glass 100, a camera 110, and a microphone 120. The smart glass 100, the camera 110, and the microphone 120 may be configured as a single device, or may be configured as separate devices that are communicably connected via a wired or wireless connection. In the embodiment described below, processing will be described using an example in which an operator who wears a smart glass 100 picks a product in a warehouse such as a distribution center. It is assumed that a plurality of products 200 with barcodes 210 are present in the warehouse. The smart glass 100 is an example of a wearable device. The smart glass 100 is also an example of an information processing device and a computer. In the following description, a configuration in which the CPU 10 of the smart glass 100 performs information processing including various determinations is described. However, the smart glass 100 functions as a display for displaying various information and can communicate with the smart glass 100. The information processing including various determinations may be performed.

FIG. 2 is a diagram illustrating an example of a hardware configuration of the smart glass 100. The smart glass 100 includes a processor such as a CPU 10, a memory 11, a camera I / F 12, a microphone I / F 13, a display 14, and a communication I / F 15. Each component is connected via a bus or the like. However, some or all of the components may be configured by separate devices that are communicably connected via wire or wirelessly.
The CPU 10 controls the entire smart glass 100. The CPU 10 executes processing based on a program stored in the memory 11 to realize processing shown in the flowchart of FIG. The memory 11 stores a program, data used when the CPU 10 executes processing based on the program, and the like. For example, the program may be stored in a non-transitory recording medium and read into the memory 11 via the input / output I / F. The camera I / F 12 is an interface for connecting the smart glass 100 and the camera 110. The microphone I / F 13 is an interface for connecting the smart glass 100 and the microphone 120. The display 14 is a display for realizing AR (Augmented Reality). The communication I / F 15 is an interface for communicating with another device, for example, a server device or the like via wire or wireless.
The camera 110 captures a barcode or the like attached to the product based on a request from the smart glass 100. The microphone 120 inputs the worker's voice to the smart glass 100 as voice data, or outputs the voice in response to a request from the smart glass 100.

FIG. 3 is a flowchart illustrating an example of main information processing of the information processing system.
In S10, the CPU 10 acquires a picking list that is a list of products to be picked. The CPU 10 acquires the picking list by photographing the barcode 310 of the list 300 printed on the paper or the like shown in FIG. Further, the CPU 10 may acquire a picking list from a server device that can communicate via a network. The picking list is an example of list information regarding products to be processed.
In S11, the CPU 10 substitutes 1 for the variable n.
In S12, the CPU 10 sets the nth product in the acquired picking list as a product to be processed. In the example of FIG. 4, location number: 100-100, product code: 123456789, product name: rucksack (black), number: 1 product is the product to be processed.
In S <b> 13, the CPU 10 displays the product to be processed on the display 14. FIG. 5 is a diagram illustrating an example in which information on a product to be processed (picked) is displayed on the display 14. An operator can perform picking based on information displayed on the display 14.
In S <b> 14, the CPU 10 determines whether or not the worker has arrived at the storage location of the product to be processed. For example, the CPU 10 determines that the worker has arrived at the storage location of the product to be processed when a predetermined voice input is made by the worker via the microphone 120. The predetermined voice input is, for example, “OK. Arrival”. If the CPU 10 determines that the worker has arrived at the storage location of the product to be processed (YES in S14), the CPU 10 proceeds to S15 and determines that the worker has not arrived at the storage location of the product to be processed ( NO in S14), the process of S14 is repeated.
Here, the CPU 10 requests the operator to input the location number of the storage location of the product to be processed by voice or the like, and based on whether the input location number is the location number of the product to be processed, the operator It may be determined whether or not the product has arrived at the storage location of the product to be processed.

In S <b> 15, the CPU 10 displays a message on the display 14 to read the barcode of the product to be processed. FIG. 6 is a diagram illustrating an example of a barcode reading message. As shown in FIG. 6, a message for reading a barcode is displayed on the display 14 together with information on the product to be processed. Based on this message, the worker picks the product to be processed. When the bar code of the product is read, the CPU 10 may notify that the bar code has been read via the microphone 120, for example, “Pipip!” As shown in FIG. Good.
In S <b> 16, the CPU 10 reads the barcode of the product selected by the operator, which is taken by the camera 110, and acquires the product code indicated by the barcode. The product barcode or the product code indicated by the barcode is an example of product identification information.
In S17, the CPU 10 determines whether the product code acquired in S16 is the product code to be processed based on whether or not the product code acquired in S16 matches the product code of the product to be processed in S12. Determine whether or not. If the CPU 10 determines that the product code is the product code of the processing target (YES in S17), the process proceeds to S19. If the CPU 10 determines that the product code is not the product code of the processing target (NO in S17), the process proceeds to S18.
In S <b> 18, since the CPU 10 is not a barcode of the product to be processed, the CPU 10 displays a message to read the code again on the display 14.

In S <b> 19, the CPU 10 displays a voice input request message on the display 14. FIG. 7 is a diagram illustrating an example of a voice input request message. As shown in FIG. 8, the display 14 displays a voice input request message to read out the last three digits of the product code. Based on this message, the operator reads out the last three digits of the product code of the product to be processed. In the example of FIG. 8, the product code in which the last three digits of the product code requesting voice input are hidden is displayed on the display 14.
In S <b> 20, the CPU 10 acquires audio data input via the microphone 120. Both or either of S19 and S20 is an example of a reception process that accepts input of all or part of product identification information.
In S21, the CPU 10 analyzes the last three digits of the product code as a result of analyzing the acquired audio data and the last three digits of the product code represented by the barcode read by the camera 110 (that is, in S17). It is determined whether or not the product code of the product code determined to be processed matches the last three digits of the product code. If CPU 10 determines that they match (YES in S21), it proceeds to S23, and if it determines that they do not match (NO in S21), it proceeds to S22.
In S22, the CPU 10 displays a message prompting re-input on the display 14, as shown in FIG. Further, the CPU 10 may notify that the last three digits of the read product code does not match the last three digits of the product code of the product to be processed via the microphone 120. Good. After the process of S22, the CPU 10 returns to the process of S20 and acquires the audio data again. The CPU 10 may return to the process of S19 after the process of S22.
In S23, as shown in FIG. 10, the CPU 10 sends a message indicating that the last three digits of the read product code matches the last three digits of the product code of the processing target product. This is displayed on the display 14. Further, the CPU 10 may notify the fact that the last three digits of the read product code matches the last three digits of the product code of the processing target product via the microphone 120. Good.

In S <b> 24, the CPU 10 determines whether or not processing has been performed for all the products in the picking list. If the CPU 10 determines that processing has been performed for all products on the picking list (YES in S24), the processing of the flowchart shown in FIG. 3 is terminated, and processing has not been performed on all products on the picking list. If determined (NO in S24), the process proceeds to S25.
In S25, the CPU 10 increments the value of the variable n by one. Then, the CPU 10 returns to the process of S12.
The processing shown in FIG. 3 is an example, and if the CPU 10 determines YES in the processing of S21, it further requests input of the number of products and determines whether or not the correct number of products has been picked. You may make it do. If the CPU 10 determines that the correct number of products has been picked, the CPU 10 proceeds to the processing of S23, and if it is determined that the correct number of products has not been picked, an error message may be displayed. . Further, the input of the product code is not limited to the lower 3 digits, but may be the upper 3 digits, or the lower 4 digits and the upper 4 digits. Further, the product code may be input every other digit, or not limited to a part, but may be all. In addition, the input of the product code is not limited to voice input, and may be input by gesture or other input via some input device. Further, the code is not limited to a barcode, and may be a two-dimensional code, an RFID tag or the like in which a product code is stored.

  As mentioned above, although preferable embodiment of this invention was explained in full detail, this invention is not limited to the specific embodiment which concerns.

According to the processing of the above-described embodiment, it is possible to appropriately determine whether the read content is appropriate.
This point will be described in more detail as follows.
Conventional infrared barcode readers cannot be read unless they are close to each other, so it is considered that unintended products will not be read in the first place. If a reading error occurs, the barcode itself is damaged. It was limited to such a case.
However, in the case of the method of reading the barcode with the camera provided in the smart glass as in the present embodiment, when trying to read the barcode of the product to be picked as the performance of the camera increases, for example, FIG. As shown in Fig. 3, there are cases where multiple products are captured in the camera's field of view, and the barcode of the product placed next to the pick target enters the camera's field of view and is unintentionally read. It is possible to do.
For this reason, even if there is an automatic collation function that determines whether or not the item is to be picked, in order to confirm whether or not the bar code of the product that the operator intended to read has been read, Error checking is becoming increasingly important. This is effective in the following cases, for example.
If the picking instruction is to pick the product code “123456789” as shown in FIG. 5, it is assumed that the operator starts the operation by misunderstanding that the product code “123456788” must be picked.
Therefore, when trying to pick the product code “123456788” (when trying to read it with the camera), the operator unintentionally reads the product code “123456789” of the product stacked next to it with the camera. Suppose.
Here, since the object of the picking instruction is the product code “123456789”, an error does not occur even when the above-described automatic matching function is provided.
However, if the work progresses while the product code that the operator thinks has been read differs from the product code that has actually been read, the worker will receive a pick instruction again for the product that should have been picked. There may be confusion in picking work, such as feeling that it is.
Therefore, according to the processing of the present embodiment, as described above, the actually read product code (product code read by the camera) and the product code that the operator thinks read (product code read out by voice) , It is possible to prevent the occurrence of confusion in the subsequent picking operation.
In addition, the present invention includes a configuration in which barcodes of a plurality of products are read at a time and the suitability of reading is continuously confirmed. For example, if there are two products to be picked and the product codes to be read are “123456789” and “123456788”, the operator reads two product codes at a time, The last three digits of the product code “789” and “788” are sequentially input by voice with a predetermined time interval, and the operator reads the two actually read product codes (product codes read by the camera). It may be configured to continuously determine whether or not two product codes that are considered to be the same (a product code read out by voice) match.
Moreover, according to the process of embodiment mentioned above, the determination process in the smart glass 100 can be processed more rapidly. Moreover, according to the process of each embodiment mentioned above, the process of an information processing system can be performed more efficiently. In addition, according to the processing of each embodiment described above, it is possible to appropriately determine the suitability of the read content by simpler information processing than in the past, so the CPU utilization rate and usage rate of the smart glass 100 are lowered. be able to.
