[0013] The control unit 11 is composed of a CPU and a ROM, executes the program stored in the storage unit 13, and controls the management terminal 1. For example, a RAM is used as the main memory 12. The main memory 12 is a work area of the control unit 11. The storage unit 13 is a storage area for storing programs and data. The control unit 11 performs arithmetic processing based on the program read from the main memory 12, the program stored in an external storage medium, and the data input by the input unit 14.

[0014] The display unit 15 has a display screen. The control unit 11 outputs a video signal for displaying an image on the display screen according to the result of the arithmetic processing.

[0015] The communication interface 16 can be connected to the communication network 4 wirelessly or by wire, and can transmit and receive data to and from the server device 2 via the communication network 4. The data received via the communication interface 16 is loaded into the main memory 12 and becomes the object of arithmetic processing by the control unit 11.

[0016] The server device 2 can store the program used in the handy terminal 3 that is created or updated according to the operation of the management terminal 1. The program stored in the server device 2 is downloaded by the handy terminal 3.

[0017] Figure 3 is a block diagram showing the configuration of the server device according to an embodiment of the present invention. The server device 2 includes a control unit 21, a main memory 22, a storage unit 23, and a communication interface 24, which are respectively connected by a bus.

[0018] The control unit 21 consists of a CPU and ROM, and executes programs stored in the storage unit 23 to control the server device 2. The control unit 21 also has an internal timer for timing. The main memory 22 is the work area of ​​the control unit 21. The storage unit 23 is a storage area for saving programs and data. The control unit 21 performs program execution processing based on programs read from the main memory 22, programs stored on external storage media, and information received from the management terminal 1.

[0019] The communication interface 24 can be connected to the communication network 4 wirelessly or via a wired connection, and can send and receive data with the management terminal 1 or handheld terminal 3 via the communication network 24. The data received via the communication interface 24 is loaded into the main memory 22 and subjected to calculation processing by the control unit 21.

[0020] The handheld terminal 3 is not particularly limited as long as it is a computer device that can be carried by a person. The handheld terminal 3 is a concept that includes, for example, conventional mobile phones, tablet terminals, and smartphones, and may also be a portable terminal used for business purposes. The user who operates the handheld terminal 3 is not particularly limited. The user who operates the handheld terminal 3 may be the same as or different from the user who operates the management terminal 1.

[0021] Figure 4 is a block diagram showing the configuration of a handheld terminal according to an embodiment of the present invention. The handheld terminal 3 comprises a control unit 31, a main memory 32, a storage unit 33, an input unit 34, a display unit 35, a communication interface 36, a reading unit 37, and an imaging unit 38, all of which are connected by a bus. Note that the handheld terminal 3 only needs to have at least the control unit 31, the main memory 32, the storage unit 33, and the communication interface 36, and does not need to have all of these.

[0022] The control unit 31 consists of a CPU and ROM, and executes programs stored in the storage unit 33 to control the handheld terminal 3. The main memory 32 is the work area of ​​the control unit 31. The storage unit 33 is a storage area for saving programs and data. The control unit 31 performs calculations based on programs read from the main memory 32, programs downloaded from the server device 2, data input from the input unit 34, data received from the server device 2, data read by the reading unit 37, and / or data read and encoded by the imaging unit 38.

[0023] The display unit 35 has a display screen. The control unit 31 outputs a video signal for displaying an image on the display screen according to the result of the calculation processing. The display screen may be a touch panel equipped with a touch sensor. In this case, the touch panel functions as an input unit 34.

[0024] The input unit 34 is not particularly limited as long as it is capable of inputting data. For example, it may be capable of inputting data via operation buttons, a touch panel, or voice input.

[0025] The communication interface 36 can connect to the communication network 4 wirelessly and can send and receive data with the server device 2 via the communication network 4. The communication interface 36 can also send and receive data via short-range wireless communication (e.g., Bluetooth®). Data received by the server device 2 via the communication interface 36 is loaded into the main memory 32 and processed by the control unit 31.

[0026] The reading unit 37 is capable of reading data from the RF tag. The data read by the reading unit 37 is loaded into the main memory 32 and becomes the subject of calculation processing by the control unit 31.

[0027] The imaging unit 38 is capable of capturing images of the real world. It can capture images of the real world and acquire still or moving images. These image data can be stored in the storage unit 33 of the handheld terminal 3 or transmitted to the server device 2. Furthermore, if there are codes such as one-dimensional codes or two-dimensional codes in the real world, the imaging unit 38 can capture these codes. The captured image data is encoded and converted into data such as URLs or text.

[0028] Next, the program creation process will be explained. Figure 5 is a flowchart of the program creation process according to an embodiment of the present invention. The management terminal 1 accesses the server device 2 and launches an application for creating or updating a program to be executed on the handheld terminal 3 (step S1). Once the application is launched, the management terminal 1 may be operated to select which of the multiple tasks the program for will be created or updated.

[0029] Next, the user operates the input section 14 of the management terminal 1 to select an instruction to be executed on the handheld terminal (step S2). An instruction is a unit of command that causes the handheld terminal to perform a process. In step S2, when selecting an instruction, multiple instructions are provided as pre-selected options, and the user can choose from these.

[0030] Instructions are not particularly limited, but examples include "display information," "checkboxes," "radio buttons," "arithmetic operations," "photo capture," "voice input," "QR code reading," "Bluetooth connection," "RF tag reading," "data acquisition," and "query execution." A program is created by combining these multiple instructions in the appropriate order.

[0031] "Information Display" is an instruction for displaying characters and symbols on the display screen of the handheld terminal 3. "Checkbox" is an instruction for selecting an item from multiple options displayed on the display screen of the handheld terminal 3. "Variable Input" is an instruction for prompting the input of a variable to the handheld terminal 3. "Arithmetic Operations" is an instruction for performing arithmetic operations based on a certain numerical value. "Photography" is an instruction for capturing images of the real world with the imaging unit 38. "Voice Input" is an instruction for inputting voice using the input unit 34. "QR Code Reading" is an instruction for reading a QR code using the imaging unit 38. "Bluetooth Connection" is an instruction for connecting via Bluetooth to other devices and equipment with communication functions using the communication interface 36. "RF Tag Reading" is an instruction for reading an RF tag using the reading unit 37. "Data Acquisition" is an instruction for acquiring data from the server device 2 using the handheld terminal 3. "Execute query" is an instruction to access server device 2 from handheld terminal 3 and update the data on server device 2.

[0032] Next, the user operates the management terminal 1 to input elements for customizing the instructions (step S3). The elements for customizing the instructions may differ for each instruction. Some elements may be specific to a particular instruction, while others may be required (or available) for input in any type of instruction.

[0033] To give a specific example of the elements unique to the instructions, "Information Display" is an instruction for displaying characters and symbols on the display screen of the handheld terminal 3. As an element for customization, it is possible to input characters and symbols to be displayed on the display screen.

[0034] "Variable Input" is an instruction that prompts the user to input a numerical value by operating the operation buttons (numeric keypad) of the handheld terminal 3. As a customization element, it is possible to input which item the input value will be treated as data for. For example, by inputting as a customization element that the input result should be output as the item "Quantity of Products," the input numerical value can be stored in association with the item "Quantity of Products" in the handheld terminal 3 or server device 2 and used as the target of calculation processing in other instructions.

[0035] For "basic arithmetic operations," you can input formulas that specify which data items to use and how to perform the arithmetic operations as a customization element. For example, if the program you are creating is for "inventory management," you can calculate the "inventory valuation" item from the formula "quantity of goods" × "unit price of goods."

[0036] For "data acquisition," one customization option is to input which item in the database on the storage unit of server device 2 the data should be retrieved from. By operating the handheld terminal 3 and inputting the item "product type," the numerical value of the item "unit price of product" corresponding to the item "product type" can be retrieved from server device 2.

[0037] If you select "QR code (registered trademark) reading," you can input which item the reading result should be treated as data for. For example, by inputting that the result of reading the QR code (registered trademark) should be output as the item "product identification code," the code read by the QR code (registered trademark) can be stored in association with the item "product identification code" in the handheld terminal 3 or server device 2, and can then be used for calculation processing in other instructions.

[0038] In any type of instruction, elements that require input include, for example, "the action to be taken by the user," "line number," "next action upon success," and "next action upon failure."

[0039] "Actions expected from the user" is the information displayed on the front screen of the handheld terminal 3 as the action expected from the user. For example, in the case of "QR code (registered trademark) scanning," information such as "Please scan the product's QR code (registered trademark)" would be entered.

[0040] The "Line number" is identification information used to identify the instruction selected in step S2. The "Next action on success" is information used to identify the next instruction to be executed after the previous instruction has been completed. For example, you can enter the "Line number" of the next instruction to be executed as the "Next action on success." The "Next action on failure" is information used to identify the next instruction to be executed if the previous instruction could not be executed for any reason. For example, you can enter the "Line number" of the next instruction to be executed as the "Next action on failure."

[0041] In this way, by identifying which instruction to execute next in the event of success or failure, it is possible to determine the order in which instructions are executed and to combine multiple instructions.

[0042] Furthermore, elements that can be entered according to the instructions include "message to display on success" and "message to display on failure." Users can choose whether or not to enter these elements. In addition, different messages can be entered for each instruction. For example, in the case of "QR code (registered trademark) reading," if the reading of the QR code (registered trademark) fails, an error message such as "QR code (registered trademark) reading failed" can be displayed.

[0043] By operating the management terminal 1, for example by pressing the confirmation button, the contents of the instructions entered in steps S2 and S3 are confirmed (step S4). Steps S2 to S4 can be executed repeatedly. By repeatedly executing steps S2 to S4, multiple instructions can be registered, and by combining these multiple instructions, it becomes possible to create a program that enables the handheld terminal 3 to implement desired functions while linking the handheld terminal 3 and the server device 2.

[0044] For example, when creating a program to register purchased goods as inventory, one can combine "QR code reading" to read the QR code (registered trademark) attached to the product and identify the product type, "variable input" to input the quantity of the product, and "query execution" to register the identified product type and quantity in the database of server device 2. In this way, by operating the handheld terminal 3, it is possible to register a new quantity in association with the product type in a table set up in the database of server device 2. It is also possible to update the data registered in the database of server device 2 by combining instructions.

[0045] Furthermore, for example, when querying the database of server device 2 to check the quantity of already registered inventory items, a "checkbox" for the user to select the type of item they want to check, "data acquisition" to retrieve the quantity data corresponding to the selected item type from server device 2, and "information display" to display the acquired data can be combined. In this way, by operating the handheld terminal 3, the user can access the inventory management table of server device 2 and display the inventory quantity corresponding to the item type selected by the user on the handheld terminal 3.

[0046] Steps S2 to S4 are repeated, and multiple required instructions are entered to generate a program that reflects the content of these instructions (step S5). Once the user has finished entering multiple instructions, they can proceed to step S5 by operating the handheld terminal 3 and pressing the button to request program generation.

[0047] The program generation in step S5 is performed on server device 2. Program generation is performed, for example, by the following method: Server device 2 has incomplete source code pre-registered for each instruction. By adding the elements for customizing the instruction entered in step S3 to this incomplete source code, source code (program) usable on the handheld terminal can be obtained.

[0048] The generated program is stored in server device 2 (step S6). Steps S1 to S6 complete the program creation process.

[0049] Next, the program update process will be explained. Figure 6 is a flowchart of the program update process according to an embodiment of the present invention. The program update process can be carried out by performing the same processes as the program creation process. For example, steps S11, S12 to S15 each execute the same processes as steps S1, S2 to S5 each.

[0050] First, the management terminal 1 accesses the server device 2 and launches an application to create or update a program to be executed on the handheld terminal 3 (step S11). Next, the management terminal 1 operates the input section 14 to select the instruction that needs to be changed from the previously entered instructions (step S12).

[0051] Next, the user operates the management terminal 1 to input elements for customizing the instructions (step S13). By operating the management terminal 1, for example, pressing the confirmation button, the user confirms the contents of the instructions entered in steps S12 and S13 (step S14). Steps S12 to S14 can be repeated. By repeatedly executing steps S12 to S14, modifications can be made to multiple instructions. In addition, it is possible to add new instructions separately from steps S12 to S14.

[0052] Steps S12 to S14 are repeated to input multiple necessary instructions, and then a program reflecting the content of these instructions is generated (step S15). The program generation in step S15 is performed on server device 2.

[0053] The generated program replaces the original program and is stored in server device 2 (step S16). The program modification process is completed by executing steps S11 to S16.

[0054] In the program creation process described in steps S1 to S6, or the program update process described in S11 to S16, a program is created or updated to be executed on the handheld terminal 3. However, it is also possible to create or update a program to be executed on the server device 2 using the same process.

[0055] Next, the program execution process will be explained. Figure 7 is a flowchart of the program execution process according to an embodiment of the present invention. The user operates the handheld terminal 3 to launch an application for executing a program stored in the server device 2 on the handheld terminal 3 (step S21).

[0056] When the application is launched, the program created by the program creation process or updated by the program update process is downloaded from the server device 2 and installed (step S22). It is preferable to download the program stored in the server device 2 each time the application is launched. It is preferable that the program download is performed automatically. By downloading the program each time the application is launched, it is possible to download the updated program even if the program has been updated since the last download. It is also possible to allow the user to choose whether or not to download the program before the program download starts.

[0057] Before proceeding from step S21 to step S22, it may be possible to pre-select which of several tasks the program for which task will be downloaded. Next, the downloaded program is executed (step S23). The downloaded program (source code) is converted into machine code line by line by the interpreter and executed, or it is executed based on the corresponding machine code pre-configured in the interpreter. By executing the downloaded program, the instructions set in steps S2 to S4 or S12 to S14 are executed according to the set execution order. After executing steps S21 to S23, the program execution process is completed.

[0058] In this example, in step S23, the program is executed using machine code corresponding to the source code via an interpreter. However, it is also possible to generate a compiled program in step S15, and then download and execute this compiled program in steps S22 and S23.

[0059] Next, we will explain the process when you run the downloaded program, using a specific example. For example, we will explain the case when you run a program to register purchased goods in inventory. Here, we will explain a case where the instructions combine "QR code reading" to read the QR code (registered trademark) attached to the product and identify the type of product, "variable input" to input the quantity of the product, and "query execution" to register the identified product type and quantity in the database of server device 2.

[0060] Figure 8 is a flowchart of the inventory registration process for a product according to an embodiment of the present invention. Figure 9 is a diagram of the product management table according to an embodiment of the present invention. First, a message requesting the user to read the QR code (registered trademark) attached to the product is displayed on the display screen of the handheld terminal 3 (step S31). The message displayed here is the information entered as "action to be taken by the user" in step S3. The user operates the handheld terminal 3 to read the QR code (registered trademark) attached to the product (step S32). The handheld terminal 3 analyzes the read QR code (registered trademark) and converts it into information that can identify the type of product (product identification information) (step S33).

[0061] Next, a message prompting the user to enter the quantity of goods is displayed on the screen of the handheld terminal 3 (step S34). The message displayed here is the information entered in step S3 as the "action to be taken by the user". The user operates the handheld terminal 3 to enter the quantity of goods (step S35).

[0062] Next, the product identification information identified by the QR code (registered trademark) and the quantity of the product entered are transmitted from the handheld terminal 3 to the server device 2 (step S36). When the server device 2 receives the product identification information and the quantity of the product (step S37), the product management table 40 of the server device 2 is updated (step S38). The product management table 40 stores the quantity of the product 42 in association with the product identification information 41, and when the product identification information and the quantity of the product are received in step S37, the received product identification information and the quantity of the product are registered in the product management table 40. Steps S31 to S38 complete the product inventory registration process.

[0063] Next, as a concrete example of the processing that occurs when a program is executed, we will explain the case of executing a program to check product inventory. Here, we will explain a case in which the instructions combine a "checkbox" for the user to select the type of product they want to check, "data acquisition" to obtain quantity data corresponding to the selected product type from server device 2, and "information display" to display the acquired data.

[0064] Figure 10 is a flowchart showing a product inventory confirmation process according to an embodiment of the present invention. First, a checkbox for selecting one product from several types of products is displayed on the display screen of the handheld terminal 3 (step S41). When the user operates the handheld terminal 3 to check the checkbox and select a product (step S42), a request to transmit the quantity of the product, along with product identification information corresponding to the selected product, is sent to the server device 2 (step S43).
