2.2 Display of Home Screen FIG. 5 is a diagram showing a screen display example of the display device of the present invention. The control unit 20 of the display device 200 generates the home screen 500 based on the application stored in the storage unit 40. The home screen 500 is the most basic screen in which a plurality of pages are prepared as screen displays. The control unit 20 displays the home screen 500 on both the first display unit 31a and the second display unit 31b as one screen or on only one of them.

  Home screen 500 includes a list of applications stored in storage unit 40. In this embodiment, various applications can be displayed in the form of a widget 520, a window 510, and a button 530. The widget 520, the window 510, and the button 530 are shown in the example of the home screen 500 in FIG. As shown, the tiled design is displayed without overlapping each other.

  The widget 520 is a single-function application that has been reduced in size so that it can be installed on the home screen 500, and can always be started in a form that can be viewed on the home screen 500. For example, a widget 520 that displays the date and time is displayed.

  The window 510 is a small rectangular display area prepared independently in the display screen, and displays an image or document in the display area with the application open. . In the present embodiment, on a home screen 500, a plurality of applications windows 510 are simultaneously displayed in a multi-window format with a plurality of applications activated simultaneously. As shown in FIG. 5, in the present embodiment, the control unit 20 performs a “message in the warehouse” window 510a corresponding to the product management application 41a in the warehouse, a “message message” window 510b corresponding to the message message application 41b, and a memo. A “memo” window 510c corresponding to the application 41c and a “Todo” window 510d corresponding to the Todo application 41d are simultaneously displayed. At this time, for example, the control unit 20 displays the product whose expiration date is approaching in the “Marumi in storehouse” window 510a, displays the newest message message in the “message message” window 510b, and displays the newest note in the “memo” ”Window 510c and the current schedule is displayed in“ Todo ”window 510d.

  An application that is not activated is displayed in the form of a button 530 that is a rectangular object.

  When the widget 520, the window 510, and the button 530 are selected by the user on the home screen 500, the control unit 20 displays only the screen of the application corresponding to the selection as the first display unit 31a and the second display unit 31b. Are displayed on the entire display screen of either or both. For example, when any of the windows 510a, 510b, 510c, 510d displayed in the multi-window format is selected, the display screen is changed from the home screen 500 to screens 540a, 540b, 540c, It switches to 540d.

2.3 Home Screen Display Change FIG. 6 is a flowchart of screen display control according to the present invention. 7 to 10 are diagrams showing display examples of the screen, where (a) shows before change and (b) shows after change. While the power is turned on, the display device 200 sends product information, message messages, memos, and information on ToDo in the refrigerator 100 to the server 700 via the input unit 10 for a certain period (for example, 5 minutes). Request) and obtain (at step S601). For example, a list of all products in the refrigerator 100, a list of message messages, a list of memos, and a list of ToDo included in the in-store product DB 71a, message message DB 71b, memo DB 71c, and Todo DB 71d held by the server 700, respectively. get. The control unit 20 stores the acquired information in the storage unit 40. The product information acquired from the server 700 includes, for example, at least product name, purchase date or date of receipt, and expiration date information.

  The control unit 20 determines whether or not the subject that is the user has been imaged by the imaging unit 11 within a predetermined range (for example, within 1 m) from the refrigerator 100 (step S602). If the subject is not imaged (No in step S602), it is determined that there is no person near the refrigerator 100, and a screen saver is displayed on the first display unit 31a and the second display unit 31b instead of the home screen 500. (Step S614).

  When the subject is imaged (Yes in step S602), the control unit 20 determines whether the subject is tall (step S603). For example, the height is measured by detecting the position of the face of the subject. If the height is less than 140 cm, it is determined that the height is not high (No in step S603), and the position of the window 510 is changed. For example, as illustrated in FIG. 7, the positions of the widget 520, the window 510, and the button 530 are inverted so that the window 510 is displayed at the bottom of the screen. This makes it easy to see the window 510 even when the height is low (such as a child).

  Based on the product information acquired in step S601, the control unit 20 determines whether there is a product with a near expiration date in the warehouse (step S605). For example, if there is a product whose expiration date is within two days from today, it is determined that there is a product with an expiration date close to the warehouse (Yes in step S605), and the size of the “Marumi in the warehouse” window 510a is changed (step). S606). Specifically, each window 510 is provided with a flag indicating that no change is made to increase the size in the case of “0” and that the change is made to increase the size in the case of “1”. , The flag corresponding to the “Marumi in the warehouse” window 510a is changed from “0” to “1”.

  The control unit 20 determines whether there is a new message message based on the information about the message message acquired in step S601 (step S607). For example, if there is a message message whose creation date is within 24 hours, it is determined that there is a new message (Yes in step S607), and the size of the “message message” window 510b is changed (step S608). Specifically, the flag corresponding to the “message message” window 510b is changed from “0” to “1”.

  The control unit 20 determines whether there is a new memo based on the information about the memo acquired in step S601 (step S609). For example, if there is a memo whose creation date is within 24 hours, it is determined that there is a new memo (Yes in step S609), and the size of the “memo” window 510c is changed (step S610). Specifically, the flag corresponding to the “memo” window 510c is changed from “0” to “1”.

  The control unit 20 determines whether there is today's schedule based on the information regarding ToDo acquired in step S601 (step S611). If there is a schedule for today (Yes in step S611), the size of the “Todo” window 510d is changed (step S612). Specifically, the flag corresponding to the “Todo” window 510d is changed from “0” to “1”.

  The control unit 20 displays the home screen 500 using both the first display unit 31a and the second display unit 31b or on either one (step S613). At this time, the size of the window 510 is changed and displayed based on the flag indicating the size change. For example, when it is determined that the height is high and only the flag corresponding to the “Marumi in the warehouse” window 510a is “1”, the window 510, the widget 520, and the button 530 are displayed as shown in FIG. The position is left as it is, and only the size of the “Marumi in the interior” window 510a is increased, and the sizes of the other windows are decreased so as not to overlap each other. As another example, when it is determined that the height is high and the flags corresponding to the “message message” window 510b and the “memo” window 510c are “1”, as shown in FIG. While maintaining the positions of the widget 520 and the button 530, the “message message” window 510b and the “memo” window 510c are increased in size, and the sizes of the other windows are decreased. As another example, when it is determined that the height is not high and only the flag corresponding to the “message message” window 510b is “1”, the position of the widget 520 remains as shown in FIG. Thus, the positions of the window 510 and the button 530 are reversed upside down, and only the size of the “message message” window 510b is increased.

  When the number of flags indicating “1” is large, all of the windows 510 corresponding to the flag indicating “1” cannot be displayed in an enlarged manner, and thus the number of windows 510 that can be enlarged and displayed is limited. For example, in this embodiment, the enlarged display of the window 510 is limited to two. The third and subsequent windows that cannot be enlarged are displayed, for example, in a blinking manner so as to prompt the operation. At this time, the priority order of the window 510 to be enlarged and displayed is set in advance, and when three or more flags indicate “1”, the window 510 to be enlarged and displayed is selected based on the priority order. The priority order may be set by the user via the input unit 10 or may be set by the control unit 20. The control unit 20 may set the priority order of the window 510 to be enlarged based on the result of the height of the subject in step S603. For example, when it is determined that the height is high, it is considered that the person is an adult, so the priority order is in the order of “Marumi in the warehouse” window 510a, “Todo” window 510d, “Memo” window 510c, and “Message message” window 510b. If it is determined that the height is not high, it is considered that the child is a child, so the “message message” window 510b, the “memo” window 510c, the “Todo” window 510d, and the “Marumi in the warehouse” window 510a Set priority in order.

  At least the window 510 changed to increase the size is displayed so that the latest information can be visually recognized. For example, if the “Marumi in the storehouse” window 510a is enlarged in step S606, the control unit 20 displays at least the product with the closest expiration date so that it can be visually recognized in the “Marume in store” window 510a. Similarly, for the windows 510b, 510c, and 510d, the control unit 20 displays at least the newest message message in the “message message” window 510b and the latest message in the “memo” window 510c, respectively. Is displayed in the “Todo” window 510d so that it can be seen. At this time, in accordance with the size of the window 510, the product, message message, memo, and today's schedule displayed in the window 510 may be enlarged or reduced. When the size of the window 510 is small, the product, the message, the memo, and a part of today's schedule may be visible or may not be visible at all. A window that displays a list of all items in the refrigerator 100, a list of message messages, a list of notes, and a list of ToDo, as well as items that are nearing their expiration date, the latest message message, the latest note, and the current schedule. The image may be enlarged and reduced in accordance with the size of 510.

3. Summary As described above, the refrigerator 100 of the present embodiment includes the display device 200, and the size and / or position of the application window 510 is determined based on predetermined conditions (steps S602, S603, S605, S607, S609, and S611). In other words, a plurality of application windows 510 are simultaneously displayed on the home screen 500 of the display device 200. Thereby, the latest information can be obtained on the home screen 500 of the display device 200 with good visibility without requiring any user operation.

4). Modification The size and position of the window 510, the widget 520, and the button 530 may be changed, or any of the window 510, the widget 520, and the button 530 may be changed. It may be impossible. For example, in the above embodiment, the size of the window 510 on the home screen is changed based on the predetermined condition.
