DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted.

[0012] It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0013] In this disclosure, a technique for displaying an information code (such as a one-dimensional barcode or a QR code (registered trademark)) in which information is stored will be described. In the following embodiment, a case in which a QR code is displayed on a display screen of a cooking appliance will be described. The cooking appliance is an example of a display system in this disclosure.

[0014] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to FIGS.

[0015] [1-1. Configuration] 1 is a perspective view of a cooking appliance 10 according to embodiment 1. Cooking appliance 10 includes a main body 11, a lid 12, a handle 13, and a user interface 20.

[0016] A container for containing an object to be heated is detachably housed inside the main body 11. The container is heated by a heating unit. The lid 12 opens and closes the opening of the main body 11. The handle 13 is grasped to open and close the lid 12.

[0017] The main body 11 contains a control device that controls the heating unit, the user interface 20, etc., and a storage device that stores data used by the control device.

[0018] The user interface 20 outputs information to the user and accepts instruction inputs from the user. An information code 25 and associated information 24 are displayed on the display screen of the user interface 20. The information code 25 and associated information 24 will be described in detail later.

[0019] 2 shows a functional configuration of cooker 10 according to embodiment 1. Cooker 10 includes a heating unit 51, a user interface 20, a control device 60, and a storage device 80.

[0020] The user interface 20 includes a display screen 21, an input unit 22, and a sound output unit 23. The display screen 21 displays a display screen generated by the control device 60. The display screen 21 may include a liquid crystal display device or the like. The input unit 22 transmits an instruction input received from a user to the control device 60. The input unit 22 may include an input device such as a button or a switch. The display screen 21 and the input unit 22 may be implemented by a touch panel or the like. The sound output unit 23 outputs a voice or a buzzer sound generated by the control device 60. The sound output unit 23 may include a speaker or a buzzer such as a piezoelectric buzzer. The buzzer sounds a pulse wave within the audible band generated by the control device 60.

[0021] The storage device 80 stores programs, data, etc. used by the control device 60. The storage device 80 may be a semiconductor memory, a hard disk, etc. The storage device 80 stores character information and associated information stored in an information code. The storage device 80 may be provided outside the control device 60, may be built into the control device 60, or both may be used in combination.

[0022] The control device 60 includes a setting reception unit 61, a heating control unit 62, a display control unit 63, a sound control unit 64, and an information code generation unit 65. These components are realized in hardware by any circuit, a computer CPU, memory, other LSI, etc., and in software by a program loaded into memory, etc., but here, functional blocks realized by the cooperation of these are depicted. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various forms, such as hardware only or a combination of hardware and software.

[0023] The setting reception unit 61 receives settings of heating conditions such as the temperature at which the object to be heated is heated, the heating time, and the type of food to be automatically cooked from the user via the input unit 22.

[0024] The heating control unit 62 controls the heating unit 51 that heats the container or the inside of the container. The heating control unit 62 controls the heating unit 51 in accordance with the settings received by the setting receiving unit 61.

[0025] The display control unit 63 controls the display on the display screen 21. The display control unit 63 displays the information code 25 on the display screen 21 together with associated information 24 different from the information code 25. The display control unit 63 displays at least a part of the associated information 24 on the display screen 21 before the information code 25.

[0026] The sound control unit 64 controls the output of sound from the sound output unit 23. The sound control unit 64 outputs sound from the sound output unit 23 when an instruction input that triggers displaying the information code 25 on the display screen 21 is received by the input unit 22.

[0027] The information code generating unit 65 reads character information to be stored in the information code 25 from the storage device 80 and generates the information code 25 by encoding the character information.

[0028] Fig. 3A shows the configuration of the user interface 20. The user interface 20 includes a display screen 21, an input unit 22, and a sound output unit 23. An operation screen for operating the cooking appliance 10 is displayed on the display screen 21. In the example of Fig. 3A, an operation screen for executing a scan connection function that receives setting information for connecting the cooking appliance 10 to a wireless router from a user's smartphone or the like is displayed.

[0029] 3A, when the user presses the "OK" button of the input unit 22, the sound control unit 64 outputs an acceptance sound from the sound output unit 23 to notify that the input has been accepted. The information code generation unit 65 generates an information code including a URL for displaying a setting screen for accepting setting information on the user's mobile terminal or the like. The display control unit 63 displays the generated information code on the display screen 21.

[0030] When the cooking appliance 10 has many types of information codes to display on the display screen 21, it is necessary to install a storage device 80 with a large storage capacity in order to store all the information codes as image data in the storage device 80. However, from the viewpoint of reducing the size, weight, manufacturing costs, etc. of the cooking appliance 10, it is desirable that the capacity of the storage device 80 is as small as possible. Therefore, in the cooking appliance 10 of the present embodiment, image data of all the information codes is not stored in the storage device 80 in advance, but only character information is stored in the storage device 80, and the character information is encoded each time an information code is displayed to generate an information code. This makes it possible to reduce the capacity of the storage device 80, and therefore the size, weight, manufacturing costs, etc. of the cooking appliance 10. In addition, when it becomes necessary to change the character information, it is only necessary to replace the character information rather than replacing the image data of the information code stored in the storage device 80, thereby improving maintainability.

[0031] If an information code is generated by encoding character information each time it is displayed, a certain delay occurs between the time the user presses the "OK" button and the time the information code is displayed on the display screen 21. Depending on the performance of the processor used, this can take anywhere from several hundred milliseconds to several seconds. For this reason, the delayed response of the cooking appliance 10 can cause discomfort to the user.

[0032] In order to solve such a problem, in the cooking appliance 10 of the present embodiment, as shown in FIG. 3B, at least a part of the associated information 24 displayed on the display screen 21 together with the information code is displayed on the display screen 21 before the information code. Here, the associated information 24 does not require a complicated generation process as in the case of the information code 25, and therefore can be displayed within, for example, 100 milliseconds after the user presses the "OK" button. While the associated information 24 is displayed on the display screen 21 in advance, the information code generation unit 65 encodes the character information to generate an information code. When the information code is generated, the display control unit 63 displays the information code 25 on the display screen 21 as shown in FIG. 3C.

[0033] In this way, cooking appliance 10 of the present embodiment first displays associated information 24 on display screen 21 immediately after the user presses the "OK" button, and then displays information code 25 on display screen 21 after information code 25 has been generated. This reduces the sense of discomfort felt by the user due to the delay before information code 25 is displayed. Also, because a certain degree of delay before information code 25 is displayed can be made acceptable to the user, there is no need to install an expensive, high-speed processor in cooking appliance 10. This allows the manufacturing cost of cooking appliance 10 to be reduced.

[0034] Since the time required to generate the information code 25 is often several hundred milliseconds to several seconds, if a method is adopted in which a character such as "Please wait" is displayed while the information code 25 is being generated and then the image of the information code 25 is switched to when the information code 25 is generated, the time for which the character such as "Please wait" is displayed may be too short for the user to understand the displayed content, and the user may feel uncomfortable. For example, such discomfort may be noticeable when the time required to generate the information code 25 is less than one second. On the other hand, in order to reduce such discomfort, it may be possible to display "Please wait" for a time that allows the user to understand the displayed content, for example, three seconds, and deliberately delay the display of the information code 25 itself. However, when the information code 25 can be displayed in a short time, making the user wait for a longer time may worsen the user experience. In the cooking appliance 10 of the present embodiment, at least a part of the associated information 24 that is displayed on the display screen 21 immediately after receiving an instruction input that triggers the display of the information code 25 continues to be displayed on the display screen 21 even after the information code 25 is displayed, so that the user can have a sufficient time to view the associated information 24, thereby reducing the sense of discomfort felt by the user. When it takes more than three seconds to generate the information code 25, the following Figs. 7A to 7C may be used. That is, instead of simply displaying the text "Please wait" in its entirety, a temporary image in the shape of the information code 25 or the text "Please wait" is displayed as additional associated information 24 together with the associated information 24 in the place where the information code 25 is originally displayed. In this way, when it takes a long time for the information code 25 to be displayed, the sense of discomfort as described above can be reduced.

[0035] As described above, the technology of the present embodiment is particularly effective when the time required to generate the information code 25, i.e., the delay time from when an instruction input that triggers display of the information code 25 is received until the information code 25 is displayed, is so short that the user may not be able to understand the content displayed on the display screen 21 during that time, for example, about a few seconds. The delay time may be, for example, less than 3 seconds, less than 2.5 seconds, less than 2 seconds, less than 1.5 seconds, less than 1 second, less than 0.9 seconds, less than 0.8 seconds, less than 0.7 seconds, less than 0.6 seconds, or less than 0.5 seconds.

[0036] The trigger for displaying the information code 25 is not limited to an instruction input via the input unit 22, but may be an instruction from another device received via a communication means such as Bluetooth (registered trademark) or infrared communication, or the fulfillment of a preset condition, etc. Also, in this example, the input unit 22 has a button arranged outside the display screen 21, but it may also be an electrostatic touch panel arranged on the display screen 21.

[0037] The information code 25 may include a one-dimensional code, a two-dimensional code, a combination of a one-dimensional code and a two-dimensional code, etc. The one-dimensional code may be a one-dimensional barcode, etc. The two-dimensional code may be a matrix code such as a QR code or a CP code, or may be a stack code in which multiple one-dimensional barcodes are stacked.

[0038] The associated information 24 may be information related to the character information stored in the information code 25, or may be information that is not related to the character information. The associated information 24 may be characters, character strings, symbols, figures, images, moving images, etc. The associated information 24 may be one piece of information, or may include multiple pieces of information.

[0039] When character information is commonly stored in a plurality of information codes 25, the associated information 24 may be an information code that stores the common character information. For example, as in the example described later in relation to Figs. 5A, 5B, and 5C, when displaying an information code 25 that stores URLs for displaying detailed information on recipes for a plurality of dishes, the protocol and domain name of each URL are common, so that the information code that stores the protocol and domain name may be stored in advance in the storage device 80 in the form of image data, for example. When displaying the information code 25 that stores the URLs for displaying detailed information on recipes for the dishes, the display control unit 63 reads out the information code that stores the protocol and domain name from the storage device 80 and displays it as the associated information 24 first, as shown in Fig. 4A. The information code generation unit 65 generates an information code 25 that stores a directory path name and a file name unique to each dish. The display control unit 63 displays the generated information code 25 as shown in Fig. 4B. The information code 25 may be an information code that combines a plurality of information codes, such as a stacked barcode, a composite symbol, or a linked QR code. This makes it possible to reduce the amount of character information stored in the information code 25, thereby reducing the delay time until the information code 25 is displayed. Also, the processing load can be reduced.

[0040] When generating a QR code as the information code 25, the information code generation unit 65 generates multiple QR codes by encoding the same character information multiple times, evaluates each of the multiple generated QR codes from the viewpoint of low reading error, etc., and designates the best QR code as the information code 25. Since the character information to be stored in the information code 25 is predetermined in the cooking appliance 10, a generation algorithm or parameters may be used that ensures that the QR code evaluated as the best is generated as described above. This makes it possible to omit the procedure of generating multiple QR codes and evaluating the best QR code, thereby shortening the time required to generate the information code 25.

[0041] The timing at which the sound control unit 64 outputs the acceptance sound from the sound output unit 23 may be immediately after accepting the input of the "OK" button, or when a predetermined time, for example 100 milliseconds, has elapsed after accepting the input of the "OK" button, or when the accompanying information 24 is displayed on the display screen 21, or when the information code 25 is displayed on the display screen 21.

[0042] When a plurality of display screens 21 are provided, the associated information 24 and the information code 25 may be displayed on the same display screen 21, or on different display screens 21. In the former case, the information code 25 is displayed at a position where it does not overlap with at least a part of the associated information 24. That is, at least a part of the associated information 24 is displayed on the display screen 21 together with the information code 25 even after the information code 25 is displayed. This can improve the visibility of the associated information 24. In the latter case, the information code 25 is displayed so as not to overlap with the associated information 24, so that the associated information 24 is displayed on the display screen 21 together with the information code 25 even after the information code 25 is displayed.

[0043] Fig. 5A shows an operation screen for displaying an instruction manual. When the user presses the "OK" button on the operation screen shown in Fig. 5A, the display control unit 63 displays, on the display screen 21, associated information 24 indicating that an information code 25 for displaying the instruction manual will be displayed in advance, as shown in Fig. 5B. The information code generation unit 65 generates the information code 25 by encoding the URL for displaying the instruction manual. When the information code 25 is generated, the display control unit 63 displays the generated information code 25 on the display screen 21, as shown in Fig. 5C.

[0044] Fig. 6A shows an operation screen for selecting a dish to be automatically cooked by cooker 10 from a menu of dishes that cooker 10 can automatically cook. When a user presses the "OK" button on the operation screen shown in Fig. 6A, display control unit 63 displays accompanying information 24 indicating that information code 25 for displaying details of the recipe of the selected dish will be displayed on display screen 21 in advance, as shown in Fig. 6B. Information code generation unit 65 generates information code 25 by encoding a URL for displaying detailed information of the recipe. When information code 25 is generated, display control unit 63 displays the generated information code 25 on display screen 21, as shown in Fig. 6C.

[0045] FIG. 7A shows an operation screen similar to FIG. 6A. When the user inputs the "OK" button on the operation screen shown in FIG. 7A, the display control unit 63 displays, on the display screen 21, the associated information 24 indicating that the information code 25 for displaying the details of the recipe of the selected dish is to be displayed and the associated information 26 indicating that the information code 25 is waiting to be displayed, as shown in FIG. 7B. The associated information 26 is displayed at a position where the information code 25 is to be displayed. The information code generating unit 65 generates the information code 25 by encoding the URL for displaying the detailed information of the recipe. When the information code 25 is generated, the display control unit 63 replaces the associated information 26 displayed at the position where the information code 25 is to be displayed with the information code 25, as shown in FIG. 7C. This improves the degree of freedom in displaying the associated information 24, 26 and the information code 25. In this case, the associated information 26 becomes invisible when the information code 25 is displayed, so it may be information that does not cause any problems even if the user cannot understand the contents. The display size of the associated information 26 may be different from that of the information code 25. When it takes 2 to 3 seconds or more to display the information code 25, if only the associated information 24 is displayed, the user may feel uncomfortable as if the display process of the information code 25 has been interrupted. In such a case, by displaying the associated information 26, the user can recognize that the process is ongoing, thereby reducing the sense of discomfort. The associated information 24 is displayed on the display screen 21 together with the information code 25 even after the information code 25 is displayed.

[0046] [1-2. Operation] The operation and function of cooker 10 configured as above will be described below. A user grasps handle 13 to open lid 12 and places an object to be heated, such as food ingredients, in the container. The user closes lid 12, sets heating conditions such as temperature, heating time, and type of food to be automatically cooked via user interface 20, and issues a command to start heating. Heating control unit 62 of cooker 10 controls heating unit 51 according to the set heating conditions, and heats the object to be heated placed in the container.

[0047] When the information code 25 is displayed on the display screen 21 of the user interface 20, the display method according to the first embodiment is executed. FIG. 8 is a flowchart showing the procedure of the display method according to the first embodiment. When an instruction input that triggers the display of the information code 25 on the display screen 21 of the user interface 20 is received by the input unit 22 (S10), the sound control unit 64 outputs a reception sound from the sound output unit 23 (S12). The display control unit 63 reads the associated information 24 from the storage device 80 and displays it on the display screen 21 (S14). The information code generation unit 65 reads character information from the storage device 80 and encodes the character information to generate the information code 25 (S16).

[0048] Until the generation of the information code 25 is completed (N in S18), the information code generation unit 65 continues to generate the information code 25. When the generation of the information code 25 is completed (Y in S18), the display control unit 63 displays the generated information code 25 on the display screen 21 (S20).

[0049] [1-3. Effects, etc.] As described above, in the present embodiment, cooking appliance 10, which is an example of a display system, includes display screen 21 and display control unit 63 that displays information code 25 on display screen 21 together with associated information 24 that is different from information code 25. Display control unit 63 displays at least a part of associated information 24 on display screen 21 before information code 25. This reduces the sense of discomfort felt by the user due to the delay until information code 25 is displayed. Furthermore, the capacity of storage device 80 can be reduced, thereby reducing the size, weight, manufacturing costs, and the like of cooking appliance 10.

[0050] In this embodiment, the information code 25 is displayed at a position that does not overlap with at least a part of the associated information 24. This makes it possible to improve the visibility of the associated information 24.

[0051] In this embodiment, the information code 25 is displayed by replacing at least a part of the associated information 24. This improves the degree of freedom in displaying the associated information 24 and the information code 25. Even if it takes 2 to 3 seconds or more to display the information code 25, it is possible to reduce the sense of incongruity that the display process of the information code 25 has been interrupted.

[0052] In the present embodiment, cooking appliance 10 includes input unit 22 for receiving an instruction input from a user, sound output unit 23 for outputting sound, and sound control unit 64 for outputting sound from sound output unit 23 when an instruction input that triggers displaying information code 25 on display screen 21 is received by input unit 22. This makes it possible to reduce the discomfort felt by the user due to the delay between when a reception sound is sounded to notify that an instruction input that triggers displaying information code 25 on display screen 21 has been received and when information code 25 is displayed on display screen 21.

[0053] In the present embodiment, the information code 25 is a two-dimensional barcode. This makes it possible to reduce the discomfort felt by the user due to the delay in displaying the two-dimensional barcode, which takes time to generate.

[0054] In the present embodiment, cooking appliance 10 includes an information code generation unit 65 that encodes character information to generate information code 25. This reduces the discomfort felt by the user due to the delay in generating and displaying information code 25.

[0055] In this embodiment, the display method includes a step of displaying at least a part of the associated information 24 on the display screen 21 prior to the information code 25 when displaying the information code 25 together with associated information 24 different from the information code 25 on the display screen 21, and a step of displaying the information code 25 on the display screen 21. This reduces the sense of discomfort felt by the user due to the delay until the information code 25 is displayed. Furthermore, the capacity of the storage device 80 can be reduced, thereby reducing the size, weight, manufacturing costs, etc. of the cooking appliance 10.

[0056] In this embodiment, the display program causes the computer to function as a display control unit 63 that displays the information code 25 together with associated information 24 different from the information code 25 on the display screen 21, and the display control unit 63 displays at least a part of the associated information 24 on the display screen 21 prior to the information code 25. This reduces the sense of discomfort felt by the user due to the delay until the information code 25 is displayed. Furthermore, the capacity of the storage device 80 can be reduced, thereby reducing the size, weight, manufacturing costs, etc. of the cooking appliance 10.

[0058] The technology of the present embodiment is not limited to cooking appliances, but can also be applied to home appliances, mobile terminals, information devices, amusement devices, cash registers, and the like. For example, in a cash register, when an information code for payment is displayed on a display screen, accompanying information including the payment amount and the like may be displayed on the display screen before the information code. Also, in an amusement device, when an information code in which a URL for displaying special information, effects, and the like is stored is displayed on a display screen, accompanying information including a character string or an image that stimulates the expectation of the special information, effects, and the like may be displayed on the display screen before the information code. In this case, the information code may be displayed on the display screen when it is generated, or may be displayed on the display screen after a further delay until a predetermined time has passed to increase the expectation of the player.
