[0011] Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding parts will be denoted by the same reference numerals and will not be repeated in the description.

[0012] Figure 1 is an external perspective view showing the display device 2. An example of the display device 2 is a notebook computer. The display device 2 includes a main unit 4 and a display unit 8. The display unit 8 can be opened and closed relative to the main unit 4 via a hinge 6. The display unit 8 includes a display. The display is provided with a display panel such as an LCD (Liquid Crystal Display), and the display panel is connected to the circuit board of the main unit 4 by a cable or the like.

[0013] Figure 1 shows the display unit 8 in the open position. In the following description, when the display unit 8 of the display device 2 is in the open position, direction X will be described as the direction from left to right in the width direction of the main unit 4. Similarly, direction Y will be described as the direction from the bottom to the top in the vertical direction of the main unit 4. Direction Z will be described as the direction from the front to the rear in the front-to-back direction of the main unit 4.

[0014] Inside the main unit 4 is a circuit board containing electronic components (not shown). Input devices such as a keyboard and touchpad are provided on the top surface of the main unit 4.

[0015] The main unit 4 has a USB (Universal Serial Bus) connector 12 for connecting to a circuit board and an interface unit 14 at its side end. The USB connector 12 connects to the terminals of a USB cable (not shown) or a USB memory device (not shown) for inputting and outputting data. The interface unit 14 is connected to the terminals of a display cable (not shown) or an internet cable (not shown).

[0016] Examples of display cables and their connectors include D-Sub (D-subminiature) 15-pin cables / D-Sub 15-pin connectors, DVI (Digital Visual Interface) cables / DVI connectors, HDMI (High-Definition Multimedia Interface) cables / HDMI (High-Definition Multimedia Interface) connectors, or DISPLAY Port cables / DISPLAY Port connectors.

[0017] Examples of internet cables and their connectors include LAN (Local Area Network) cables / LAN cable connectors, or Ethernet® cables / Ethernet® cable connectors.

[0018] Display device 2 may be a computer device such as a desktop PC or a laptop computer. It may also be a communication device such as a landline telephone, a mobile phone, or a smartphone. It may also be an information terminal equipped with a display.

[0019] The display device 2 can be connected to an overhead display device via a USB cable connected to the USB connector 12 or an internet cable connected to the interface unit 14, and can also be connected to a video conferencing system. Furthermore, the display device 2 can communicate with external terminals described later via a USB cable or an internet cable.

[0020] Next, the details of the display device 2 will be described with reference to Figure 2. Figure 2 is a diagram showing the detailed configuration of the display device 2. As shown in Figure 2, in addition to the display unit 8 described in Figure 1, the display device 2 further includes a communication unit 16, an acquisition unit 18, a storage unit 20, and a control unit 22. The communication unit 16 will be described later in Figure 3.

[0021] The acquisition unit 18 acquires location information of the display device 2. An example of the acquisition unit 18 is the Global Positioning System, i.e., GPS.

[0022] The storage unit 20 stores the content to be displayed on the display unit 8. The storage unit 20 includes a storage device and stores data and computer programs. Specifically, the storage unit 20 includes a main storage device such as semiconductor memory and an auxiliary storage device such as semiconductor memory and / or a hard disk drive. The storage unit 20 may also include removable media.

[0023] The control unit 22 controls the display unit 8, the communication unit 16, the acquisition unit 18, and the storage unit 20, and further controls the operation of each part of the display device 2. Specifically, the control unit 22 includes a processor such as a CPU (Central Processing Unit). The processor of the control unit 22 controls the operation of each part of the display device 2 by executing a computer program stored in the storage device of the storage unit 20.

[0024] In addition, the control unit 22 determines whether or not to convert the content to be displayed on the display unit 8 based on the information acquired from the communication unit 16 or the acquisition unit 18, converts the content to be displayed on the display unit 8 based on the determination, and displays the converted content on the display unit 8. (First typical example) Next, a first typical example of the display device 2 according to this embodiment will be described with reference to Figures 3 to 5(b). Figure 3 is a diagram showing the first typical example of the display device 2. Figure 4 is a diagram showing an example of the display in the first typical example. Figures 5(a) and 5(b) are diagrams showing other examples of the display in the first typical example of the display device 2.

[0025] As shown in Figure 3, the display device 2 is connected to one or more external terminals 24 via a cable 28. There is no limit to one display device 2. Multiple display devices 2 may be connected. External terminals 24A to 24D are shown as examples, but are not limited to these. One external terminal 24 may be connected, or five or more may be connected. Note that unless there is a need to distinguish between external terminals 24A to 24D, they will be referred to simply as external terminal 24.

[0026] The external terminal 24 may be a computer device such as a desktop PC or a laptop computer. It may also be a communication device such as a landline telephone, a mobile phone, or a smartphone. It may also be a video phone system or an overhead display device. It may also be an information terminal equipped with a display.

[0027] External terminals 24A to 24D each include screens 26A to 26D. However, screens 26A to 26D will be referred to as screen 26 unless there is a need to distinguish between them. The descriptions of external terminals 24 and screen 26 apply throughout this application.

[0028] Furthermore, although Figure 3 shows the display device 2 and the external terminal 24 connected by a wired cable 28, they may also be connected wirelessly. The description of the cable 28 and wireless communication applies throughout this application.

[0029] The communication unit 16 of the display device 2 connects the communication between the display device 2 and the external terminal 24. Once communication is established, the control unit 22 of the display device 2 makes the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 share the same display.

[0030] Furthermore, the communication unit 16 communicates with a video conferencing system or other external terminal 24 via the USB connector 12 and the interface unit 14. The communication unit 16 includes a transmitting unit and a receiving unit. An example of a wired communication unit 16 is a LAN (Local Area Network) cable, and an example of wireless communication is wireless LAN, Wi-Fi (Wireless Fidelity), or Bluetooth (registered trademark).

[0031] As shown in Figure 4, the display unit 8 displays the first object 30A. Specifically, the display unit 8 displays images of shortcuts for launching software or applications (hereinafter referred to as "first software 60"), images of files, or images of folders containing files (hereinafter referred to as "first interface image 32A"), as well as word processing software, spreadsheet software, document viewer software, music editing software, or image editing software that are launched when the first interface image 32A is clicked or otherwise accessed.

[0032] Furthermore, the first interface image 32A may be accompanied by a first character image 34A that represents the content. Hereinafter, the first interface image 32A, the first character image 34A that is displayed in conjunction with the first interface image 32A, and the screen of the opened software will be collectively referred to as the first object 30A.

[0033] The display unit 8 shown in Figure 4 displays the first object 30A. Normally, multiple first objects 30A are displayed on the display unit 8, but for the sake of drawing creation, only one first object 30A is displayed.

[0034] The first object 30A is a first interface image 32A provided by the developer or seller of the first object 30A, a first character image 34A representing character information provided by the developer or seller, or an image of the first software 60, which will be activated when the first interface image 32A or the first character image 34A is instructed.

[0035] However, the user of the external terminal 24 shown in Figures 5(a) and 5(b) may be in a competitive relationship with the developer or seller of object 30. Therefore, if the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared, it may cause problems if the user of the external terminal 24 can view the first object 30A.

[0036] For example, the first interface image 32A shown in Figure 4 is an image provided by, for example, the developer or seller of the first software 60, and therefore may be an image that evokes the developer or seller. For example, if the developer or seller is Company A, it may be an image that is recognizable as "A". Similarly, the first character image 34A may be a character image that evokes Company A, the developer or seller of the first software 60. For example, it may be a character image that is recognizable as "Company A".

[0037] Therefore, the control unit 22 communicates with the external terminal 24 to share the screen 26 of the external terminal 24 and the display unit 8, converts the first object 30A into a second object 30B that does not evoke the first object 30A, and displays the second object 30B on the screen 26 of the external terminal 24.

[0038] Specifically, the control unit 22 determines whether or not to convert the first object 30A displayed on the screen 26 of the external terminal 24 shown in Figure 5(a) to the second object 30B shown in Figure 5(b). Since the display unit 8 of the display device 2 shown in Figure 4 and the screen 26 of the external terminal 24 shown in Figure 5(a) are shared, the first object 30A shown in Figure 5(a) is usually the same as the first object 30A shown in Figure 4.

[0039] In other words, both the first object 30A in Figure 4 and the first object 30A in Figure 5(a) display a first interface image 32A that is recognizable as "A" and a first character image 34A that is recognizable as "A Company".

[0040] Furthermore, the second object 30B is a second interface image 32B that does not evoke the first interface image 32A, a second character image 34B that does not evoke the first character image 34A, or second software 62 in which some or all of the images included in the first software 60 have been erased.

[0041] The software displayed on the screen 26 of the external terminal 24 is identical to the first software 60 displayed on the display unit 8 of the display device 2, but for the sake of explanation, it will be referred to as the second software 62. The second software 62 has some or all of the data displayed in the first software 60 erased.

[0042] The control unit 22 activates the communication unit 16 to determine whether communication has been established between the display unit 8 of the display device 2 and the screen 26 of the external terminal 24. If it is determined that communication has been established, the control unit 22 determines whether or not to convert the first object 30A, which should be displayed on the screen 26 of the external terminal 24, into a second object 30B. If it is determined to convert it into a second object 30B, the control unit 22 reads the second object 30B corresponding to the first object 30A from the storage unit 20.

[0043] In other words, the "B" in the second interface image 32B shown in Figure 5(b) is an image that does not evoke the "A" in the first interface image 32A. Also, the second character image 34B, which is perceived as "〇△□", is a character image that does not evoke "Company A", the developer or seller of the software that is activated by instructing the first object 30A.

[0044] The control unit 22 converts the image of the first object 30A displayed on the screen 26 of the external terminal 24 shown in Figure 5(a) into the image of the second object 30B shown in Figure 5(b). For example, the control unit 22 converts the first interface image 32A, which is perceived as "A", into the second interface image 32B, which is perceived as "B" and does not evoke "A", and displays it on the screen 26. Also, the control unit 22 converts the first character image 34A, which is perceived as "Company A", into the second character image 34B, which is perceived as "〇△□" and does not evoke "Company A", and displays it on the screen 26.

[0045] According to this embodiment, when the display device 2 shares its screen with another person's external terminal 24, object images such as icons and file names that you do not want others to see can be converted into other object images that do not evoke the original object images.

[0046] The display device 2 includes a storage unit 20 that stores the first object 30A and the second object 30B in association with each other.

[0047] Each time the screen 26 of the external terminal 24 and the display unit 8 of the display device 2 are shared, or each time the position of the display device 2 changes in the second typical example described later, it is cumbersome for the user to consider what design the second interface image 32B or the second character image 34B should be for the second object 30B.

[0048] Therefore, the storage unit 20 stores the first object 30A and the second object 30B that the user has set in advance, in association with each other. Specifically, the storage unit 20 includes a table (not shown) that associates the first object 30A and the second object 30B.

[0049] The table stores the first interface image 32A and the first character image 34A as the first object 30A. The first interface image 32A is an image corresponding to icons, files, folders, the first wallpaper (described later), the first software 60, the data displayed in the first software 60, business partners, developers, manufacturers, sellers, and users. The first character image 34A is a character image displayed in conjunction with the first interface image 32A, and is a character image that describes the contents of the files and folders.

[0050] In addition, a second interface image 32B and a second character image 34B are stored as a second object 30B corresponding to the first object 30A. The second interface image 32B includes icons, files, folders, the second wallpaper described later, the second software 62, data displayed in the second software 62, and images corresponding to business partners, developers, manufacturers, sellers, and users.

[0051] The second character image 34B is a character image displayed in conjunction with the second interface image 32B, and is a character image that describes the contents of the files and folders. However, in the storage unit 20, tables are not an essential component.

[0052] According to this embodiment, there is no need to set how to display the second object 30B each time the screen 26 of the external terminal 24 and the display unit 8 of the display device 2 are shared.

[0053] Next, the control unit 22 converts the first object 30A into the second object 30B before either the display unit 8 of the display device 2 or the screen 26 of the external terminal 24 is activated.

[0054] When the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared, if the first object 30A has been converted to the second object 30B on the screen 26 of the external terminal 24 before sharing begins, the user is relieved from the hassle of having to consider whether or not it has been converted to the second object 30B, which is preferable.

[0055] Therefore, the control unit 22 activates the communication unit 16 to determine whether communication has been established between the display unit 8 of the display device 2 and the screen 26 of the external terminal 24. If it is determined that communication has been established, the control unit 22 determines whether or not to convert the first object 30A, which should be displayed on the screen 26 of the external terminal 24, into a second object 30B. If it is determined to convert it into a second object 30B, the control unit 22 reads the second object 30B corresponding to the first object 30A from the storage unit 20.

[0056] Before sharing between the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 begins, or before either the display unit 8 or the screen 26 of the external terminal 24 is activated, the control unit 22 converts the first object 30A to be displayed on the screen 26 of the external terminal 24 into a second object 30B.

[0057] The control unit 22 displays the second object 30B on the screen 26 of the external terminal 24 when sharing between the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 begins, or when either of the screens 26 of the external terminal 24 is activated.

[0058] The point at which the control unit 22 converts the first object 30A to the second object 30B may be, for example, when the user's affiliation is confirmed by an email received from the user of the external terminal 24 that shares the first object 30A, or when it is confirmed that the power of the display device 2 or the external terminal 24 has been turned ON.

[0059] According to this embodiment, the user of the display device 2 does not need to consider whether the first object 30A has been converted to the second object 30B on the screen 26 of the external terminal 24 before sharing between the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 begins.

[0060] Furthermore, the user of the display device 2 does not need to consider whether the first object 30A, which should be displayed on the display unit 8 of the display device 2, has been converted to the second object 30B before the display unit 8 of the display device 2 is activated.

[0061] Next, with reference to Figures 6(a) and (b), an example of the second software 62 in which some or all of the images contained in the first software 60 have been erased will be described. Figures 6(a) and 6(b) show further other examples of the first typical example.

[0062] As shown in Figure 6(a), when the control unit 22 is instructed to start the first software 60 by clicking the first object 30A on the display unit 8 of the display device 2, the control unit 22 does not display some or all of the images contained in the second software 62 on the screen 26 of the external terminal 24, as shown in Figure 6(b).

[0063] The first software 60 is activated by the instruction of the first object 30A and is, for example, word processing software, spreadsheet software, or drawing software.

[0064] If the first software 60 is word processing software or spreadsheet software, problems may arise if the data entered into the first software 60 or other images are viewed by interested parties.

[0065] Therefore, corresponding to the first typical example, when the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared, the control unit 22 starts the first software 60 in accordance with the instruction given for the first object 30A displayed on the display unit 8 of the display device 2. Then, the control unit 22 causes the second software 62 to be displayed on the screen 26 of the external terminal 24. At this time, the control unit 22 does not display some or all of the character images contained in the second software 62.

[0066] Specifically, as shown in Figure 6(a), the first software 60 displays a text image 64 indicating that it billed Company A 156,000 yen, Company B 103,000 yen, and Company C 98,000 yen for March.

[0067] As shown in Figure 6(b), the control unit 22 prevents the display of part or all of the character image 66 corresponding to the billing amount included in the second software 62 on the screen 26 of the external terminal 24. However, the part or all of the character image 66 that is not displayed in the second software 62 is not limited to the billing amount portion. It may also be part or all of the character image 66 displayed in the second software 62, such as the company name or individual name.

[0068] According to this embodiment, it is possible to avoid the inconvenience caused by others seeing images displayed in word processing software or spreadsheet software. Furthermore, even if the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared, data from software that you do not want others to see can be converted into an image that does not evoke the original data. In addition, the user of the display device 2 can perform tasks such as inputting, deleting, or converting data on the first software 60 without others seeing it.

[0069] Furthermore, according to this embodiment, when the display device 2 and the external terminal 24 share a screen, the image of the first object 30A, such as an icon, that you do not want the user of the external terminal 24 to see can be converted into a second object 30B that does not evoke the image of the first object 30A. This makes it possible to avoid the inconvenience that would arise from showing the image of the first object 30A to a third party who is in a competitive relationship with the developer or seller of the first software 60 that is activated by instructing the first object 30A.

[0070] Next, corresponding to the first typical example, the control unit 22 converts the second object 30B to the first object 30A after the sharing between the screen 26 of the external terminal 24 and the display unit 8 is completed.

[0071] After ending the sharing between the screen 26 of the external terminal 24 and the display unit 8 of the display device 2, the user of the display device 2 needs to perform the cumbersome task of converting the conversion from the first object 30A to the second object 30B on the external terminal 24, which was controlled by the display device 2, back to the first object 30A.

[0072] Therefore, the control unit 22 controls the external terminal 24 to terminate the sharing of the screen 26 and the display unit 8 of the display device 2. After that, the control unit 22 controls the external terminal 24 to terminate the control of converting the first object 30A to the second object 30B and to convert the second object 30B back to the first object 30A.

[0073] Specifically, the control unit 22 determines, based on the communication unit 16, whether or not the communication connection between the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 has been disconnected. If it is determined that the communication connection has been disconnected, the control unit 22 determines whether or not to convert the second object 30B to the first object 30A.

[0074] If it determines that the object should be converted to the first object 30A, the control unit 22 reads the first object 30A corresponding to the second object 30B from the storage unit 20 and converts the second object 30B to the first object 30A.

[0075] According to this embodiment, the user of the display device 2 does not need to consider returning the second object 30B to the first object 30A after the sharing between the screen 26 of the external terminal 24 and the display unit 8 of the display device 2 has ended.

[0076] Next, the operation of the display device 2 according to the first typical example will be described with reference to Figures 7 and 8. Figures 7 and 8 are flowcharts showing the operation of the display device 2 according to the first typical example. As shown in Figures 7 to 8, the process includes steps S10 to S36. The control unit 22 executes the processes from steps S10 to S36. Specifically, it is as follows.

[0077] As shown in Figure 7, first, in step S10, the control unit 22 starts the display device 2. The process then proceeds to step S12.

[0078] In step S12, the display unit 8 of the display device 2 is activated. The process then proceeds to step S14.

[0079] In step S14, the display unit 8 displays the first object 30A. The process then proceeds to step S16.

[0080] In step S16, the control unit 22 instructs the communication unit 16 to establish a communication connection between the display device 2 and the external terminal 24. The process then proceeds to step S18.

[0081] In step S18, the control unit 22 determines whether or not to convert the first object 30A on the screen 26 of the external terminal 24 to the second object 30B. If it is determined not to convert to the second object 30B (No in step S18), the process proceeds to step S30 shown in Figure 8. If it is determined to convert to the second object 30B (Yes in step S18), the process proceeds to step S20.

[0082] In step S20, the control unit 22 identifies the first object 30A to be converted into the second object 30B (Figure 5(a)). The process then proceeds to step S22.

[0083] In step S22, the control unit 22 reads the second object 30B corresponding to the first object 30A from the storage unit 20. The process then proceeds to step S24 shown in Figure 8.

[0084] In step S24 shown in Figure 8, the control unit 22 converts the first object 30A to be displayed on the screen 26 of the external terminal 24 into a second object 30B. The process then proceeds to step S26.

[0085] In step S26, the control unit 22 controls the communication unit 16 to start sharing between the display unit 8 of the display device 2 and the screen 26 of the external terminal 24. The process then proceeds to step S28.

[0086] In step S28, the control unit 22 displays the second object 30B on the screen 26 of the external terminal 24. The process then proceeds to step S30.

[0087] In step S30, the control unit 22 controls the display unit 8 of the display device 2 and the screen of the external terminal 24. Determine whether or not to terminate sharing with 26. If it is determined not to terminate sharing (No in step S30), repeat the determination in step S30. If it is determined to terminate sharing (Yes in step S30), proceed to step S32.

[0088] In step S32, the control unit 22 controls the communication unit 16 to disconnect communication between the display device 2 and the external terminal 24. The process then proceeds to step S34.

[0089] In step S34, the control unit 22 shuts down the power supply to the display unit 8. The process then proceeds to step S36.

[0090] In step S36, the control unit 22 shuts down the power supply to the display device 2. Then the process ends.

[0091] (Second typical example) Next, a second typical example of the display device 2 according to this embodiment will be described with reference to Figures 9(a) and 9(b), and Figures 10(a) and 10(b). Figures 9(a) and 9(b) are diagrams showing an overview of the second typical example of the display device 2. Figures 10(a) and 10(b) are diagrams showing display examples in the second typical example.

[0092] In the second typical example, the display device 2 comprises an acquisition unit 18, a display unit 8, and a control unit 22, as described in Figure 2. The acquisition unit 18 acquires the location information of the display device 2. The display unit 8 displays a first object 30A, or a second object 30B that does not evoke the first object 30A. Based on the location information of the display device 2, the control unit 22 converts the first object 30A to the second object 30B, or converts the second object 30B to the first object 30A, and displays them on the display unit 8.

[0093] As shown in Figure 9(a), when a user of the display device 2 leaves the area owned by the user's organization or visits a business partner, the first object 30A displayed on the display device 2 may be seen by someone who does not belong to the user's organization.

[0094] Other individuals who do not belong to the same organization as the user of display device 2 may be in competition with the developer or seller of the software corresponding to the first object 30A (Figure 4), and showing the first object 30A to such individuals may cause them inconvenience.

[0095] Therefore, the acquisition unit 18 acquires the position information of the display device 2.

[0096] The control unit 22 determines, based on the location information, whether or not to leave the first area 40. The first area 40 is, for example, the area owned by the organization to which the user of the display device 2 belongs. If the control unit 22 determines that the display device 2 has left the first area 40, it determines whether or not to convert the first object 30A displayed on the display unit 8 of the display device 2 into a second object 30B.

[0097] Figure 10(a) shows the first object 30A displayed on the display unit 8 of the display device 2. The first object 30A displays a first interface image 32A that is visually recognizable as "A" and a first character image 34A that is displayed together with the first interface image 32A and is visually recognizable as "A Company".

[0098] When the control unit 22 determines that the first object 30A should be converted to the second object 30B, it reads the second object 30B corresponding to the first object 30A from the storage unit 20. The control unit 22 converts the first object 30A to the second object 30B.

[0099] In other words, the control unit 22 converts the first interface image 32A, which is perceived as "A," into a second interface image 32B, which is perceived as "B" and does not evoke "A," and displays it on the display unit 8. Also, the control unit 22 converts the first character image 34A, which is perceived as "Company A," into a second character image 34B, which is perceived as "〇△□" and does not evoke "Company A," and displays it on the display unit 8.

[0100] Even if the display device 2 or display unit 8 is not activated, the control unit 22 may, based on the position information, convert "A" to "B" or "Company A" to "Company B" when the display device 2 leaves the first area 40. The control unit 22 may perform a similar conversion before the display device 2 leaves the first area 40. The control unit 22 may also perform a similar conversion before the display device 2 or display unit 8 is activated.

[0101] Next, as shown in Figure 9(b), the control unit 22 determines whether the display device 2 enters the second region 42 based on the position information of the display device 2 acquired by the acquisition unit 18. The second region 42 is, for example, a business partner that is in a competitive relationship with the developer or seller of the first software 60 corresponding to the first object 30A.

[0102] When the display device 2 determines that it has entered the second area 42, the control unit 22 determines whether or not to convert the first object 30A displayed on the display device 2 into a second object 30B. If it determines to convert the first object 30A into a second object 30B, the control unit 22 reads the second object 30B corresponding to the first object 30A from the storage unit 20.

[0103] The control unit 22 converts the first object 30A into the second object 30B. The control unit 22 displays the second object 30B on the display unit 8. The display configuration of the first object 30A and the second object 30B is the same as that described in Figures 10(a) and 10(b).

[0104] Furthermore, as explained in Figure 6(a), the control unit 22 may convert and display the display of the first software 60 related to the first object 30A displayed on the display unit 8 of the display device 2, and the display of the second software 62 related to the second object 30B, as shown in Figure 6(b), based on the position information acquired by the acquisition unit 18.

[0105] According to this embodiment, based on the position information of the display device 2, the image of the first interface image 32A associated with the first object 30A that the user does not want others to see, and the first character image 34A associated with the first object 30A, can be converted into a second object 30B that does not evoke the first object 30A.

[0106] Next, relating to the second typical example, the control unit 22 converts the second object 30B to the first object 30A based on the position information of the display device 2.

[0107] The user of display device 2 must perform the cumbersome task of changing the second object 30B displayed on the display unit 8 of display device 2 back to the first object 30A after leaving the territory owned by the organization they are visiting, or after returning to the territory owned by the organization to which the user belongs.

[0108] Therefore, the acquisition unit 18 acquires the position information of the display device 2. Based on the position information, the control unit 22 controls the display device 2 to convert the second object 30B back to the first object 30A.

[0109] Specifically, the control unit 22 activates the acquisition unit 18 to acquire location information. Based on the location information, the control unit 22 determines whether the display device 2 has entered the first area 40 (Figure 9) or has left the second area 42.

[0110] When the display device 2 determines that it has entered the first area 40 or exited the second area 42, the control unit 22 determines whether or not to convert the second object 30B to the first object 30A. If it is determined that it should be converted to the first object 30A, the control unit 22 reads the first object 30A corresponding to the second object 30B from the storage unit 20 and converts the second object 30B to the first object 30A.

[0111] According to this embodiment, the user of the display device 2 does not need to consider returning the second object 30B to the first object 30A after leaving the territory owned by the organization they visited, or after returning to the territory owned by the organization to which the user belongs.

[0112] Furthermore, the control unit 22 may convert the first object 30A to the second object 30B based on location information indicating that the display device 2 is within the first region 40, or based on participant information.

[0113] Specifically, when the display device 2 is located within the first area 40 and the display unit 8 of the display device 2 must be shown to a third party other than the developer or seller of the first object 30A, the control unit 22 determines whether or not to convert the first object 30A to the second object 30B based on participant information obtained from the domain name of the email, etc.

[0114] When the control unit 22 determines that the first object 30A should be converted to the second object 30B, it reads the second object 30B corresponding to the first object 30A from the storage unit 20. The control unit 22 converts the first object 30A to the second object 30B. The control unit 22 displays the second object 30B on the display unit 8.

[0115] Furthermore, the control unit 22 may convert the second object 30B to the first object 30A based on location information indicating that the display device 2 is within the first region 40, or based on participant information.

[0116] In other words, when the display device 2 is within the first area 40, and a meeting has ended or for some other reason a third party other than the developer or seller of the first object 30A no longer needs to see the display unit 8 of the display device 2, the control unit 22 converts the second object 30B back to the first object 30A based on the participant information and displays it on the display unit 8.

[0117] Specifically, the acquisition unit 18 acquires the location information of the display device 2. Based on the location information, the control unit 22 determines whether or not the display device 2 is within the first region 40. If the display device 2 is within the first region 40, the control unit 22 determines, based on the participant information, whether or not to convert the second object 30B to the first object 30A.

[0118] When the control unit 22 determines that it is appropriate to convert to the first object 30A, it reads the first object 30A corresponding to the second object 30B from the storage unit 20. The control unit 22 converts the second object 30B to the first object 30A. The control unit 22 displays the first object 30A on the display unit 8.

[0119] According to this embodiment, when the display device 2 is within the first region 40, the image of the first interface image 32A associated with the first object 30A that one does not want others to see, and the first character image 34A associated with the first object 30A, can be converted into a second object 30B that does not evoke the first object 30A.

[0120] Furthermore, according to this embodiment, when the display device 2 is within the first area 40, if the user no longer needs to show the second object 30B to another person, the user does not need to return the second object 30B to the first object 30A.

[0121] Next, the operation of the display device 2 according to the second typical example will be described with reference to Figures 11 and 12. Figures 11 and 12 are flowcharts showing the operation of the display device 2 according to the second typical example. The process shown in Figures 11 and 12 is the process when the display device 2 leaves the first area 40, as shown in Figure 9(a). As shown in Figures 11 to 12, the process includes steps S40 to S68. The control unit 22 executes the process from steps S40 to S68. Specifically, it is as follows.

[0122] As shown in Figure 11, first, in step S40, the acquisition unit 18 acquires the location information of the display device 2. Based on the location information, the control unit 22 determines whether or not the display device 2 leaves the company area (first area 40). If it is determined that the display device 2 does not leave the first area 40 (No in step S40), the control unit 22 repeats the process in step S40. If it is determined that the display device 2 leaves the first area 40 (Yes in step S40), the process proceeds to step S42.

[0123] In step S42, the control unit 22 determines whether or not to convert the first object 30A displayed on the display unit 8 of the display device 2 into a second object 30B. If it is determined not to convert it into a second object 30B (No in step S42), the control unit 22 repeats the process in step S42. If it is determined to convert it into a second object 30B (Yes in step S42), the process proceeds to step S44.

[0124] In step S44, the control unit 22 identifies the first object 30A (Figure 10(a)) to be converted into the second object 30B in the display unit 8. The process then proceeds to step S46.

[0125] In step S46, the control unit 22 reads the second object 30B corresponding to the first object 30A from the storage unit 20. The process then proceeds to step S48.

[0126] In step S48, the control unit 22 converts the first object 30A to the second object 30B before the display device 2 leaves the first area 40. The process then proceeds to step S50.

[0127] In step S50, the control unit 22 starts the display device 2. The process then proceeds to step S52.

[0128] In step S52, the control unit 22 activates the display unit 8. The process then proceeds to step S54.

[0129] In step S54, the control unit 22 causes the display unit 8 to display the second object 30B (Figure 10(b)). The process then proceeds to step S56, as shown in Figure 12.

[0130] In step S56, the control unit 22 determines whether to terminate the use of the display device 2 and shut down the power supply to the display device 2. If it is determined that the power supply to the display device 2 should not be shut down (No in step S56), the control unit 22 repeats the process in step S56. If it is determined that the power supply to the display device 2 should be shut down (Yes in step S56), the process proceeds to step S58.

[0131] In step S58, the control unit 22 first shuts down the power supply to the display unit 8. The process then proceeds to step S60.

[0132] In step S60, the control unit 22 determines whether or not to convert the second object 30B of the display unit 8 to the first object 30A. If it is determined not to convert to the first object 30A (No in step S60), the process proceeds to step S68. If it is determined to convert to the first object 30A (Yes in step S60), the process proceeds to step S62.

[0133] In step S62, the control unit 22 identifies the second object 30B to be converted to the first object 30A in the display unit 8. The process then proceeds to step S64.

[0134] In step S64, the control unit 22 reads the first object 30A corresponding to the second object 30B from the storage unit 20. The process then proceeds to step S66.

[0135] In step S66, the control unit 22 converts the second object 30B of the display unit 8 into the first object 30A. The process then proceeds to step S68.

[0136] In step S68, the control unit 22 shuts down the power supply to the display device 2. Then the process ends.

[0137] Next, other operations of the display device 2 according to the second typical example will be described with reference to Figures 13 and 14. Figures 13 and 14 are flowcharts showing other operations of the display device 2 according to the second typical example. The processes shown in Figures 13 and 14 are the processes that occur when the display device 2 enters the second region 42, as shown in Figure 9(b). As shown in Figures 13 and 14, the processes include steps S80 to S110. The control unit 22 executes the processes from steps S80 to S110. Specifically, it is as follows.

[0138] As shown in Figure 13, first, in step S80, the acquisition unit 18 acquires location information of the display device 2. Based on the location information, the control unit 22 determines whether the display device 2 enters, for example, the premises of a business partner (second area 42). If it is determined that the display device 2 does not enter the second area 42 (No in step S80), the control unit 22 repeats the process of step S80. If it is determined that the display device 2 enters the second area 42 (Yes in step S80), the process proceeds to step S82.

[0139] In step S82, the control unit 22 determines whether or not to convert the first object 30A, which is to be displayed on the display unit 8 of the display device 2, into a second object 30B. If it is determined not to convert it into a second object 30B (No in step S82), the process ends. If it is determined to convert it into a second object 30B (Yes in step S82), the process proceeds to step S84.

[0140] In step S84, the control unit 22 identifies the first object 30A (Figure 10(a)) to be converted into the second object 30B in the display unit 8. The process then proceeds to step S86.

[0141] In step S86, the control unit 22 reads the second object 30B corresponding to the first object 30A from the storage unit 20. The process then proceeds to step S88.

[0142] In step S88, the control unit 22 converts the first object 30A to the second object 30B before the display device 2 enters the second area 42. The process then proceeds to step S90.

[0143] In step S90, the control unit 22 starts the display device 2. The process then proceeds to step S92.

[0144] In step S92, the control unit 22 activates the display unit 8. The process then proceeds to step S94.

[0145] In step S94, the control unit 22 displays the second object 30B (Figure 10(b)) on the display unit 8. The process then proceeds to step S96 shown in Figure 14.

[0146] In step S96 shown in Figure 14, the control unit 22 activates the acquisition unit 18. The acquisition unit 18 acquires the position information of the display device 2. Based on the position information, the control unit 22 determines whether or not the display device 2 has left the second area 42. If it is determined that the display device 2 has not left the second area 42 (No in step S96), the control unit 22 repeats the process in step S96. If it is determined that the display device 2 has left the second area 42 (Yes in step S96), the process proceeds to step S98.

[0147] In step S98, the control unit 22 determines whether or not to convert the second object 30B of the display unit 8 to the first object 30A. If it is determined not to convert to the first object 30A (No in step S98), the process proceeds to step S106. If it is determined to convert to the first object 30A (Yes in step S98), the process proceeds to step S100.

[0148] In step S100, the control unit 22 identifies the second object 30B (Figure 10(b)) to be converted into the first object 30A in the display unit 8. The process then proceeds to step S102.

[0149] In step S102, the control unit 22 reads the first object 30A corresponding to the second object 30B from the storage unit 20. The process then proceeds to step S104.

[0150] In step S104, the control unit 22 converts the second object 30B into the first object 30A. The process then proceeds to step S106.

[0151] In step S106, the control unit 22 determines whether to terminate the use of the display device 2 and shut down the power supply to the display device 2. If it is determined that the power supply to the display device 2 should not be shut down (No in step S106), the control unit 22 repeats the process in step S106. If it is determined that the power supply to the display device 2 should be shut down (Yes in step S106), the process proceeds to step S108.

[0152] In step S108, the control unit 22 first shuts down the power supply to the display unit 8. The process then proceeds to step S110.

[0153] In step S110, the control unit 22 shuts down the power supply to the display device 2. Then the process ends.

[0154] Below, with reference to Figures 1 to 14, specific examples or variations of the first and second typical examples will be explained using further figures. Note that each specific example or variation can be classified into those corresponding only to the first typical example, those corresponding only to the second typical example, and those applicable to both the first and second typical examples. Therefore, in the explanation of each specific example or variation, it will be explained as appropriate which typical example it corresponds to.

[0155] (First example) The first specific example will be explained with reference to Figure 15. Figure 15 is a diagram showing the first specific example of the display device 2. The first specific example corresponds to the first typical example. In the first specific example, the control unit 22 converts the first object 30A to the second object 30B, or the second object 30B to the first object 30A, for each external terminal 24, each user of the external terminal 24, or each organization to which the user belongs.

[0156] As shown in Figure 15, the display device 2 and multiple external terminals 24 are connected via a cable 28. The display unit 8 of the display device 2 is shared with each of the screens 26 of the external terminals 24.

[0157] For example, when the display unit 8 shares the screens 26 of multiple external terminals 24, the organizations to which the external terminals 24 belong, the users of the external terminals 24, or the organizations to which the users belong may include stakeholders of the first software 60 relating to the first object 30A displayed on the display unit 8.

[0158] Therefore, the control unit 22 determines, based on information about the external terminal 24, the user, or the affiliated organization, whether to display the first object 30A or the second object 30B for each external terminal 24A to 24D.

[0159] As shown in Figure 15, the control unit 22 determines whether the user or organization of the external terminal 24A is a stakeholder of the first software 60. The control unit 22 determines that the user or organization of the external terminal 24A is not a stakeholder of the first software 60, and determines whether or not to display the first object 30A on the screen 26A of the external terminal 24A.

[0160] When the control unit 22 determines that the first object 30A should be displayed, it reads the first object 30A from the storage unit 20 and displays the first object 30A on the display unit 8.

[0161] Next, the control unit 22 determines whether the user or organization of the external terminals 24B to 24D is a stakeholder of the first software 60. If the control unit 22 determines that the user or organization of the external terminals 24B to 24D is a stakeholder of the first software 60, it determines whether or not to display the second object 30B on the screens 26B to 26D of the external terminals 24B to 24D.

[0162] When the control unit 22 determines that it is appropriate to display the second object 30B, it reads the second object 30B corresponding to the first object 30A from the storage unit 20 for each external terminal 24B to 24D. The control unit 22 then displays the second object 30B for each screen 26B to 26D.

[0163] The control unit 22 determines, for example, which screen 26 of the external terminal 24 to display the first object 30A or the second object 30B, based on the location information of each external terminal 24, the name of the organization to which the external terminal 24 is registered, the user name of the organization determined from the facial recognition system, the IP address of the external terminal 24, and the domain name of the contact person's email address. The control unit 22 may also read this information from the storage unit 20.

[0164] The control unit 22 causes the display unit 8 of the display device 2 to display a first object 30A which includes a first interface image 32A that is visually recognizable as "A" and a first character image 34A that is visually recognizable as "A Company".

[0165] For the external terminal 24A, the control unit 22 causes the first object 30A to be displayed on the screen 26A of the external terminal 24A.

[0166] With respect to the external terminal 24B, the control unit 22 determines from the location information of the external terminal 24B that it is a terminal belonging to a different organization from the user and is a stakeholder of the first software 60 relating to the first object 30A. The control unit 22 reads the second object 30B from the storage unit 20, which includes, for example, a second interface image 32B that is visually recognizable as "B" and a second character image 34B that is visually recognizable as "XXX", and displays it on the screen 26B of the external terminal 24B.

[0167] Similarly, with respect to the external terminal 24C, the control unit 22 determines from the name of the organization to which the external terminal 24C is registered and the name of the user of that organization that the terminal belongs to a different organization than the user. For example, it reads a second object 30B from the storage unit 20 that includes a second interface image 32B that is visually recognizable as "C" and a second character image 34B that is visually recognizable as "YYY", and displays it on the screen 26C of the external terminal 24C.

[0168] Similarly, with respect to the external terminal 24D, the control unit 22 estimates from the IP address of the external terminal 24D and the domain name of the contact person's email address that it is a terminal belonging to a different organization from the user. For example, it reads a second object 30B from the storage unit 20 that includes a second interface image 32B that is visually recognizable as "D" and a second character image 34B that is visually recognizable as "ZZZ", and displays it on the screen 26D of the external terminal 24D.

[0169] According to this embodiment, it is possible to select an external terminal 24, person in charge, or organization that may experience inconvenience if the first object 30A is viewed, and convert the first object 30A into a second object 30B.

[0170] (Second specific example) The second specific example will be explained with reference to Figures 16(a) to 17(b). Figures 16(a) and 16(b) show the second specific example of the display device 2. Figures 17(a) and 17(b) show other examples of the second specific example of the display device 2. The second specific example corresponds to the first typical example.

[0171] In the second specific example, the display unit 8 of the display device 2 indicates that the second object 30B is being displayed on the screen 26 of the external terminal 24.

[0172] When the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared, as shown in Figures 16(a) and 16(b), the first object 30A is displayed on the display unit 8 of the display device 2 and the second object 30B is displayed on the screen 26 of the external terminal 24.

[0173] However, the user of display device 2 may not realize that the first object 30A has been converted and displayed as the second object 30B on the screen 26 of the external terminal 24. Also, the user of display device 2 may forget that the data in the first software 60 is data that should not be seen by others, even though the first object 30A has been converted and displayed as the second object 30B on the screen 26 of the external terminal 24. As a result, the user of display device 2 may inadvertently point to the first object 30A displayed on the display unit 8 and open the first software 60.

[0174] Therefore, if the data of the first software 60 is data that should not be seen by others, it may be preferable for the user if the display device 2 informs the user that the first object 30A has been converted to a second object 30B and is being displayed on the screen 26 of the external terminal 24.

[0175] Therefore, the control unit 22 determines whether the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared. If it determines that they are shared, the control unit 22 determines whether or not to convert the first object 30A to the second object 30B on the screen 26 of the external terminal 24.

[0176] When the control unit 22 determines that it is time to convert to the second object 30B, it reads the second object 30B corresponding to the first object 30A from the storage unit 20. Furthermore, the control unit 22 reads the indicator 50 for display on the display unit 8 of the display device 2 from the storage unit 20. The control unit 22 displays the second object 30B on the screen 26 of the external terminal 24. Furthermore, the control unit 22 displays the indicator 50 together with the first object 30A on the display unit 8 of the display device 2.

[0177] As shown in Figure 16(b), the second object 30B is displayed on the screen 26 of the external terminal 24. In Figure 16(a), the control unit 22 displays the first interface image 32A and the first character image 34A included in the first object 30A, as well as the indicator 50, on the display unit 8. The indicator 50 indicates that the first object 30A, which includes the first interface image 32A and the first character image 34A, has been converted and displayed as the second object 30B on the screen 26 of the external terminal 24.

[0178] The indicator 50 is not limited to an arrow as shown in Figure 16(a). The indicator 50 may be modified to show the first interface image 32A or the first character image 34A with a dotted line, as shown in Figure 17(a). Alternatively, the indicator 50 may display the first interface image 32A or the first character image 34A with a pattern image added.

[0179] The indicator 50 shown in Figure 16(a) may flash an image of a graphic. Furthermore, the indicator 50 may also display a warning such as, "This object has been converted into another object and is being displayed on the external terminal 24." In other words, it is sufficient that the user of the display device 2 recognizes that the first object 30A has been converted into the second object 30B and is being displayed on the screen 26 of the external terminal 24.

[0180] Furthermore, the first interface image 32A or the first character image 34A may be displayed transparently or semi-transparently, as shown by the dotted line in Figure 17(a). The first interface image 32A or the first character image 34A may blink.

[0181] According to this embodiment, the user of the display device 2 can recognize on the display unit 8 which of the first objects 30A displayed on the display unit 8 has been converted into a second object 30B on the screen 26 of the external terminal 24.

[0182] (Third specific example) Next, a third specific example will be described with reference to Figures 18(a) to 21(b). Figures 18(a) and 18(b) show a third specific example of the display device 2. Figures 19(a) and 19(b) show another third specific example of the display device 2. Figures 20(a) and 20(b) show yet another third specific example of the display device 2. The third specific example can correspond to both the first and second typical examples.

[0183] In the first typical example, when the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared, the first wallpaper is displayed on the display unit 8 as the first object 30A, as shown in Figure 18(a). The first wallpaper is displayed across the entire surface of the display unit 8, along with the name of the developer, manufacturer, or seller of the first software 60, such as "Theta System," and a design that represents the first software 60, such as spreading rays of light.

[0184] However, unlike the first object 30A (Figure 10(a)), the first wallpaper is displayed across the entire surface of the display unit 8. Therefore, users of the display device 2 may not realize that it would be inconvenient if others saw the first wallpaper, which is the first object 30A.

[0185] Therefore, for a user who does not want others to see their first wallpaper, it may be preferable for the screen 26 of the external device 24 to display a second wallpaper that does not evoke the first wallpaper.

[0186] Therefore, the control unit 22 converts the first object 30A into the second object 30B and displays the second wallpaper, which does not evoke the first wallpaper, on the screen 26 of the external terminal 24. The second wallpaper is a design in which multiple rings overlap and expand. Here, the first wallpaper displayed on the display unit 8 of the display device 2 is referred to as the first object 30A, and the second wallpaper, which does not evoke the first wallpaper, is referred to as the second object 30B.

[0187] Furthermore, corresponding to the second typical example, the first wallpaper is displayed as the first object 30A on the display unit 8 of the display device 2. Based on the position information acquired by the acquisition unit 18, the control unit 22 converts and displays the first wallpaper shown in Figure 18(a) and the second wallpaper shown in Figure 18(b). The procedure for determination and processing by the control unit 22 is as described in the second typical example.

[0188] Next, the first object 30A shown in Figure 19(a) includes a first interface image 32A, which is an interface for launching first software 60 (Figure 6(a)), such as a spreadsheet program, and a first character image 34A, such as "E Company Document," which indicates the name of a document created using the spreadsheet program.

[0189] Corresponding to the first typical example, when the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared, the control unit 22 causes the display unit 8 of the display device 2 to display a first object 30A including a first interface image 32A and a first character image 34A. Then, the control unit 22 converts the first object 30A into a second object 30B and displays it on the screen 26 of the external terminal 24. The procedure for determination and processing by the control unit 22 is as described in the first typical example.

[0190] In other words, the first interface image 32A is converted into a second interface image 32B with a design that does not evoke the first interface image 32A, and is displayed on the screen 26 of the external terminal 24. Also, the first character image 34A is converted into a second character image 34B with a design that does not evoke the first character image 34A, such as "E Company document", such as "〇△□×", and is displayed on the screen 26 of the external terminal 24.

[0191] Furthermore, corresponding to the second typical example, the control unit 22 causes the display unit 8 of the display device 2 to display a first object 30A including a first interface image 32A and a first character image 34A, as shown in Figure 19(a). Based on the position information acquired by the acquisition unit 18, the control unit 22 converts the first object 30A, including the first interface image 32A and the first character image 34A shown in Figure 19(a), into a second object 30B including the second interface image 32B and the second character image 34B shown in Figure 19(b), and displays it on the display unit 8.

[0192] Furthermore, based on the position information acquired by the acquisition unit 18, the control unit 22 converts the second object 30B, which includes the second interface image 32B and the first character image 34A shown in Figure 19(b), into the first object 30A, which includes the first interface image 32A and the first character image 34A shown in Figure 19(a), and displays it on the display unit 8.

[0193] Next, the first object 30A shown in Figure 20(a) includes a first interface image 32A showing a file created by launching the first software 60, and a first character image 34A showing a document name such as "F Company Document" which displays the contents of the file. Furthermore, the first object 30A includes a first interface image 32A showing a folder containing one or more files, and a first character image 34A showing a document name such as "F Company Document" which displays the contents of the folder.

[0194] The determination and processing procedures of the control unit 22 corresponding to the first typical example and the determination and processing procedures of the control unit 22 corresponding to the second typical example are the same as those described in Figures 19(a) and 19(b), so redundant explanations will be omitted.

[0195] (Fourth specific example) Next, the fourth specific example will be described with reference to Figures 21(a) and 21(b). The fourth specific example corresponds to the first typical example.

[0196] When the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared, the user of the display device 2 may open the first software 60, as shown in Figure 21(a), even though the user of the external terminal 24 is in a competitive relationship with the developer or seller of object 30.

[0197] Therefore, as shown in Figure 21(a), even if the first software 60 is opened on the display unit 8 of the display device 2, as shown in Figure 21(b), it is preferable that the user's instruction is rejected on the screen 26 of the external terminal 24, the first software 60 is not opened, and the second object 30B continues to be displayed.

[0198] In the fourth specific example, the control unit 22 controls the display unit 8 so that the first software 60 does not start even if the first object 30A is indicated.

[0199] Corresponding to the first typical example, when the display unit 8 of the display device 2 and the screen 26 of the external terminal 24 are shared, the control unit 22 detects that a first object 30A, which includes a first interface image 32A and a first character image 34A displayed on the display unit 8 of the display device 2, has been instructed.

[0200] The control unit 22 determines whether or not to start the first software 60 corresponding to the first object 30A. If the control unit 22 determines to start the first software 60, it starts the first software 60 and displays the first software 60 on the display unit 8, as shown in Figure 21(a).

[0201] The control unit 22 determines whether or not to launch and display the second software 62, which corresponds to the first software 60, on the screen 26 of the external terminal 24. The control unit 22 determines that the second software 62 should not be launched, and as shown in Figure 21(b), it does not display the second software 62 on the screen 26 of the external terminal 24, and instead displays the second object 30B.

[0202] According to this embodiment, in the first typical example, even if the user of the display device 2 inadvertently points to the first object 30A on the display unit 8 of the display device 2 and starts the first software 60, the second software 62 is not started on the screen 26 of the external terminal 24, so that the data displayed on the second software 62 cannot be seen by others.
