[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 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] 4 is a block diagram showing the configuration of a handheld terminal according to an embodiment of the present invention. The handheld terminal 3 includes 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 is only required to include at least the control unit 31, the main memory 32, the storage unit 33, and the communication interface 36, and is not required to include all of these components.

[0022] The control unit 31 is composed of a CPU and a ROM, and executes programs stored in the storage unit 33 to control the handheld terminal 3. The main memory 32 is a work area for the control unit 31. The storage unit 33 is a memory area for saving programs and data. The control unit 31 performs arithmetic processing 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 arithmetic processing. The display screen may be a touch panel equipped with a touch sensor. In this case, the touch panel functions as the input unit 34.

[0024] The input unit 34 is not particularly limited as long as it is capable of inputting data, and may, for example, be capable of inputting data using an operation button, a touch panel, or voice input.

[0025] The communication interface 36 can be connected to the communication network 4 wirelessly, and can transmit and receive data to and from the server device 2 via the communication network 4. The communication interface 36 can also transmit and receive data via short-range wireless communication (for example, Bluetooth (registered trademark)). Data received by the server device 2 via the communication interface 36 is loaded into the main memory 32 and becomes the subject of arithmetic processing 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 is subjected to arithmetic processing by the control unit 31.

[0027] The imaging unit 38 is capable of capturing images of the real space. By capturing images of the real space, still images or moving images can be acquired. These image data can be stored in the storage unit 33 of the handy 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 space, the imaging unit 38 can capture images of these codes. The captured image data is encoded and converted into data such as a URL or text.

[0028] Next, the program creation process will be described. Fig. 5 is a diagram showing 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 by the handy terminal 3 (step S1). When the application is launched, it may be possible to operate the management terminal 1 to select which of a plurality of tasks a program for is to be created or updated.

[0029] Next, the user operates the input unit 14 of the management terminal 1 to select an instruction to be executed by the handheld terminal (step S2). An instruction is a unit of command for causing the handheld terminal to execute a process. When selecting an instruction in step S2, multiple instructions are provided as options in advance, and the user can select one of them.

[0030] There are no particular limitations on the instructions, but examples include "display information," "checkboxes," "radio buttons," "arithmetic operations," "photographing," "voice input," "QR code (registered trademark) reading," "Bluetooth (registered trademark) connection," "RF tag reading," "data acquisition," "query execution," etc. A program is created by combining these multiple instructions in an appropriate order.

[0031] "Information display" is an instruction for displaying characters and symbols on the display screen of the handheld terminal 3. "Check box" 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 requesting input of a variable into the handheld terminal 3. "Arithmetic operation" is an instruction for performing arithmetic operations based on a certain numerical value. "Photography" is an instruction for capturing an image of the real world using the imaging unit 38. "Voice input" is an instruction for inputting voice using the input unit 34. "QR code (registered trademark) reading" is an instruction for reading a QR code (registered trademark) using the imaging unit 38. "Bluetooth (registered trademark) connection" is an instruction for establishing a Bluetooth (registered trademark) connection with other devices or equipment equipped 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 to the handheld terminal 3. "Query execution" is an instruction for accessing the server device 2 from the handy terminal 3 and updating the data in the 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 each instruction, while other elements may be required to be input (or may be inputtable) for any type of instruction.

[0033] Here is a specific example of an element specific to an instruction: "Information display" is an instruction to display characters and symbols on the display screen of the Handy Terminal 3, and as an element for customization, you can input characters and symbols to be displayed on the display screen.

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

[0035] For "arithmetic operations," you can input the formula for which data items to perform arithmetic operations as a customization element. For example, if the program you are creating is for "inventory management," you can calculate the "inventory valuation amount" item from the formula "quantity of product" x "unit price of product."

[0036] In the case of "data acquisition," as a customization element, it is possible to input which item in the database in the storage unit of the server device 2 data should be acquired from. By operating the handy terminal 3 and inputting the item "product type," it is possible to acquire from the server device 2 the numerical value of the item "product unit price" corresponding to the item "product type."

[0037] In the case of "QR Code (registered trademark) reading", it is possible to input which item of data the reading result will be treated as. For example, by inputting that the result of reading with QR Code (registered trademark) will be output as the item "product identification code", the code read with QR Code (registered trademark) can be stored in association with the item "product identification code" in the handheld terminal 3 or the server device 2, and can be used for calculation processing in other instructions.

[0038] Elements that require input in either type of instruction include, for example, "action required of user," "line number," "next action if successful," and "next action if unsuccessful."

[0039] "Actions required of user" is information to be displayed on the front screen of the handheld terminal 3 as an action required of the user. For example, in the case of "Read QR code (registered trademark)", information such as "Please read the QR code (registered trademark) of the product" is entered.

[0040] "Line number" is identification information for identifying the instruction selected in step S2. "Next action if successful" is information for identifying the next instruction to be executed after the instruction has been executed. For example, the "line number" of the next instruction to be executed can be entered as "next action if successful." "Next action if unsuccessful" is information for identifying the next instruction to be executed if the instruction cannot be executed for some reason. For example, the "line number" of the next instruction to be executed can be entered as "next action if unsuccessful."

[0041] In this way, by specifying which instruction to execute next in the event of success or failure, the order in which instructions are executed can be determined, and multiple instructions can be combined.

[0042] Elements that can be input according to the instruction include a "message to display when successful" and a "message to display when unsuccessful." The user can choose whether or not to input these elements. Also, different messages can be input for each instruction. For example, in the case of "Read QR Code (registered trademark)," if reading the QR Code (registered trademark) fails, an error message such as "Failed to read QR Code (registered trademark)" can be displayed.

[0043] The user operates the management terminal 1, for example, by pressing the confirm button, to confirm the contents of the instructions entered in steps S2 and S3 (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 is possible to create a program that can cause the handheld terminal 3 to realize desired functions while linking the handheld terminal 3 and the server device 2.

[0044] For example, when creating a program for inventory registration of purchased products, it is possible to combine a "QR Code (registered trademark) Read" to read the QR Code (registered trademark) attached to the product and identify the product type, a "Variable Input" to input the product quantity, and a "Query Execution" to register the identified product type and quantity in the database of the server device 2. In this way, by operating the handy terminal 3, it is possible to newly register the quantity in association with the product type in a table set in the database of the server device 2. It is also possible to update data registered in the database of the server device 2 by combining instructions.

[0045] Furthermore, for example, when querying the database of the server device 2 to check the quantity of a product that has already been registered in stock, it is possible to combine a "check box" for selecting the type of product the user wants to check, a "data acquisition" for acquiring data on the quantity corresponding to the selected type of product from the server device 2, and an "information display" for displaying the acquired data. In this way, the handheld terminal 3 can be operated to access the inventory management table of the server device 2, and the number of stock quantities corresponding to the type of product selected by the user can be displayed on the handheld terminal 3.

[0046] By repeatedly executing steps S2 to S4 and inputting multiple required instructions, a program that reflects the contents of these instructions is generated (step S5). When the user has finished inputting multiple instructions, he or she can proceed to step S5 by operating the handy terminal 3 and pressing a button that requests the generation of a program.

[0047] The generation of the program in step S5 is executed by the server device 2. The generation of the program is executed, for example, by the following method. Incomplete source code for each instruction is pre-registered in the server device 2. By adding elements for customizing the instructions input in step S3 to this incomplete source code, it is possible to obtain source code (program) that can be used on the handy terminal.

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

[0049] Next, the program update process will be described. Fig. 6 is a diagram showing a flowchart of the program update process according to the embodiment of the present invention. The program update process can be carried out by executing the same process as the program creation process. For example, steps S11 and S12 to S15 are executed by executing the same process as steps S1 and S2 to S5, respectively.

[0050] First, the management terminal 1 accesses the server device 2 and starts an application for creating or updating a program to be executed by the handheld terminal 3 (step S11). Next, the input unit 14 of the management terminal 1 is operated to select an instruction that needs to be changed from among instructions that have been input in the past (step S12).

[0051] Next, the management terminal 1 is operated to input elements for customizing the instructions (step S13). The management terminal 1 is operated to, for example, press the confirm button to confirm the contents of the instructions input in steps S12 and S13 (step S14). Steps S12 to S14 can be executed repeatedly. By repeatedly executing steps S12 to S14, multiple instructions can be modified. Furthermore, it is also possible to add new instructions separately from steps S12 to S14.

[0052] Steps S12 to S14 are repeatedly executed to input a plurality of necessary instructions, and then a program reflecting the contents of these instructions is generated (step S15). The generation of the program in step S15 is executed by the server device 2.

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

[0054] The program creation process of steps S1 to S6 or the program update process of steps S11 to S16 described above involves creating or updating a program to be executed on the handheld terminal 3, but similar processes can also be used to create or update a program to be executed on the server device 2.

[0055] Next, the program execution process will be described. Fig. 7 is a diagram showing a flowchart of the program execution process according to the embodiment of the present invention. The user operates the handy terminal 3 to start an application for executing the program stored in the server device 2 on the handy 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 every time the application is launched. It is preferable that the program be downloaded automatically. By downloading the program every time the application is launched, it becomes possible to download the updated program even if the program has been updated since the last time it was downloaded. It is also possible to have the user choose whether or not to download the program before starting to download the program.

[0057] Before proceeding from step S21 to step S22, it may be possible to select in advance which of a plurality of operations to download a program for. Next, the downloaded program is executed (step S23). The downloaded program (source code) is converted line by line into machine language by an interpreter and executed, or is executed based on the corresponding machine language preset 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. By executing steps S21 to S23, the program execution process is completed.

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

[0059] Next, a specific example of the process performed when a downloaded program is executed will be described. For example, the execution of a program for registering purchased products in inventory will be described. Here, the following instructions will be combined: "Read QR Code (registered trademark)" for reading the QR code (registered trademark) attached to the product and identifying the product type; "Input variable" for inputting the product quantity; and "Execute query" for registering the identified product type and quantity in the database of the server device 2.

[0060] FIG. 8 is a diagram showing a flowchart of product inventory registration processing according to an embodiment of the present invention. FIG. 9 is a diagram showing a product management table according to an embodiment of the present invention. First, a message requesting the user to read a QR code (registered trademark) attached to a product is displayed on the display screen of the handheld terminal 3 (step S31). The displayed message is the information entered as the "action requested of 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 capable of identifying the type of product (product identification information) (step S33).

[0061] Next, a message requesting the user to input the quantity of the product is displayed on the display screen of the handheld terminal 3 (step S34). The message displayed here is the information input as the "action required of the user" in step S3. The user operates the handheld terminal 3 to input the quantity of the product (step S35).

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

[0063] Next, as a specific example of processing when a program is executed, a case where a program for checking product inventory is executed will be described. Here, a case where instructions are combined: "checkboxes" for selecting the type of product the user wants to check, "data acquisition" for acquiring quantity data corresponding to the selected type of product from the server device 2, and "information display" for displaying the acquired data will be described.
