[0062] In the virtual mobile client terminal container group 100' shown in Figure 4, three virtual mobile client terminals are configured. Thus, in one embodiment of system 1, the server 10 may configure the same number of virtual mobile client terminals as the number of mobile client terminals 100 connected to the server 10.

[0063] As shown in Figure 4, for example, multiple users can be invited to the server 10 by configuring multiple virtual mobile client terminals on a single server 10. As shown in Figure 4, operations / text inputs from each mobile client terminal 100 are transmitted to the server 10. When the server 10 receives operations / text inputs from each mobile client terminal 100, it configures a screen to be displayed on the display unit 110 of each mobile client terminal 100 according to the respective operations / text inputs. Next, the server 10 transmits the screen data to be displayed on the display unit 110 of each mobile client terminal 100 to each mobile client terminal 100. When each mobile client terminal 100 receives the screen data to be displayed on the display unit 110, it can display a screen based on the received data on its respective display unit 110.

[0064] Here, the server 10 can receive different operations / text inputs from multiple mobile client terminals 100, generate different screen data for each, and send it to each mobile client terminal 100. In one embodiment, each time a user starts using each mobile client terminal 100, the server 10 starts the corresponding virtual mobile client terminal and sends its contents to each mobile client terminal 100.

[0065] If the above operations can be completed on server 10, server 10 may control each mobile client terminal 100 by communicating with each mobile client terminal 100. Alternatively, as shown in Figure 4, a separate management server 200 may be used to centrally manage the virtual mobile client terminals of all mobile client terminals 100.

[0066] In System 1 shown in Figure 4, each mobile client terminal 100 simply transmits the data it has operated / input to the server 10, and displays the screen based on the data transmitted from the server 10 on its respective display unit 110. Therefore, in System 1 according to one embodiment, it is possible to construct a thin client system that reduces the processing load on the mobile client terminal 100 used by the user and concentrates most of the main processing on the server 10.

[0067] On the other hand, in System 1 as shown in Figure 4, various problems may occur if the settings related to the predetermined devices equipped on each mobile client terminal 100 are not properly configured according to various circumstances. In other words, problems may occur if the mobile client terminal 100 is operated in the same way as a general thin client system. The following describes these possible problems and countermeasures.

[0068] For example, as shown in Figure 5A, we can consider a scenario where text input by a user is detected on a mobile client terminal 100.

[0069] Figure 5A shows an example of a scenario in which an application, such as an internet browser, is launched on a mobile client terminal 100, and a string of characters to be searched for in a search engine is entered by the user. As shown in Figure 5A, the display unit 110 of the mobile client terminal 100 displays the application display area AD. Here, the application display area AD may be the display area of ​​the screen that is displayed based on the launch or execution of various applications. The application display area AD also includes a character input area TA. Here, the character input area TA may be an area (for example, a text box) in the application display area AD where the process or result of the user's character input is displayed. The character input area TA may be not limited to a text box, but may also be an input form, for example. In the scenario shown in Figure 5A, the user is prompted to enter characters into this character input area TA.

[0070] In the situation shown in Figure 5A, the mobile client terminal 100 provides a means for user text input, either automatically or based on user operation. Software keyboards are a widely used means of text input in mobile devices. A software keyboard is a term used in contrast to a hardware keyboard, and it is a means of detecting user text input operations on a keyboard displayed on the screen using a touch panel (touch sensor) or the like.

[0071] Generally, software keyboards tend to be placed near the bottom edge of the device (near the bottom edge of the display screen) for ease of use by the user. When a software keyboard is displayed in a situation like that shown in Figure 5A, the situation may be as shown in Figure 5B. Figure 5B shows an example in which a mobile client terminal 100 automatically or based on user input provides a software keyboard as a means of character input by the user. As shown in Figure 5B, the software keyboard display area KD may be the area on the display unit 110 where the software keyboard is displayed.

[0072] In the situation shown in Figure 5B, the software keyboard display area KD is displayed so as to cover the character input area TA (Figure 5A). In other words, in the situation shown in Figure 5B, the display of the software keyboard display area KD makes the character input area TA shown in Figure 5A invisible. In such a situation, it becomes difficult for the user to perform input operations while checking the process and results of their character input. In a typical thin client system, the hardware keyboard is physically separated from the display. Therefore, it is unlikely that such a situation would occur.

[0073] To address this situation, for example, a scroll bar (knob and / or arrow) could be provided in the display unit 110 for scrolling the application display area AD. However, if, for example, the text input area TA is located near the bottom edge of the application display area AD, scrolling to the bottom edge of the application display area AD would ultimately hide the text input area TA with the software keyboard.

[0074] Therefore, in a system 1 according to one embodiment, the mobile client terminal 100 ensures that the character input area TA of the application display area AD is not obscured even when the software keyboard is displayed, as shown in Figure 5C. As shown in Figure 5C, if the character input area TA of the application display area AD is not obscured even when the software keyboard is displayed, the user can perform input operations while confirming the process and results of their own character input. Such embodiments will be described further below.

[0075] In one embodiment of System 1, when the mobile client terminal 100 displays a software keyboard on the display unit 110, it may transmit information related to the display area of ​​the software keyboard to the server 10. Here, the information related to the display area of ​​the software keyboard may be, for example, information related to the software keyboard display area KD as shown in Figure 5B. More specifically, the information related to the display area of ​​the software keyboard may be at least one of the coordinates of the base point of the software keyboard display area KD, the width of the software keyboard display area KD, and the height of the software keyboard display area KD. The base point of the software keyboard display area KD may be various points, such as the lower right corner of the software keyboard display area KD, the upper left corner of the software keyboard display area KD, or the centroid of the software keyboard display area KD. For example, in one embodiment of System 1, the server 10 may reduce the application display area AD of the virtual mobile client terminal by the amount of the software keyboard display area KD.

[0076] In this way, when a software keyboard is displayed on the display unit 110 of the mobile client terminal 100, the character input area can be displayed without being obscured by the software keyboard. Therefore, the user of the mobile client terminal 100 can input strings of characters using the software keyboard while visually viewing the character input area.

[0077] Next, the operation of System 1 according to one embodiment will be described in more detail. Figure 6 is a flowchart illustrating the operation of System 1 according to one embodiment.

[0078] The operations described in Figure 6 and subsequent figures are described as operations of System 1 according to one embodiment. Each operation and / or process described in Figure 6 and subsequent figures may be performed by at least one of the server 10 and the mobile client terminal 100 according to one embodiment. For example, at least a portion of each operation and / or process described in Figure 6 and subsequent figures may be performed by the server 10 if it can be completed as an operation by the server 10. Also, at least a portion of each operation and / or process described in Figure 6 and subsequent figures may be performed by the mobile client terminal 100 if it can be completed as an operation by the mobile client terminal 100. Furthermore, at least a portion of each operation and / or process described in Figure 6 and subsequent figures may be performed by the server 10 and the mobile client terminal 100 working together, if possible.

[0079] When the operation shown in Figure 6 begins, the system 1 according to one embodiment determines whether or not to display a software keyboard on the display unit 110 of the mobile client terminal 100 (step S10). In step S10, the system 1 may automatically display the software keyboard as a trigger, for example, by displaying a character input area TA on the display unit 110 of the mobile client terminal 100. Alternatively, in step S10, the system 1 may display the software keyboard in response to user operations on the mobile client terminal 100. User operations may include, for example, input operations on keys to display the software keyboard, or operations to switch to a mode that displays the software keyboard.

[0080] If it is determined in step S10 that the software keyboard should not be displayed, system 1 may terminate the operation shown in Figure 6. On the other hand, if it is determined in step S10 that the software keyboard should be displayed, system 1 executes the operation of the next step S20. In step S20, system 1 causes the application display area AD of the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100 to be reduced in size.

[0081] In step S20, the server 10 may generate data for a display screen in which the application display area AD of the virtual mobile client terminal corresponding to the mobile client terminal 100 has been reduced. In this case, the reduction of the application display area AD may be in accordance with the size of the software keyboard display area KD displayed on the display unit 110.

[0082] In step S20, the server 10 may also generate display screen data that includes the character input area TA in the application display area AD of the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100.

[0083] Furthermore, in step S20, the mobile client terminal 100 may reduce the application display area AD of the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100. In this case, the reduction of the application display area AD may be in accordance with the size of the software keyboard display area KD displayed on the display unit 110.

[0084] In one embodiment, if the application display area AD does not include the character input area TA, it may not be necessary to reduce the size of the application display area AD. In such cases, the operation of step S20 may be skipped. Figure 7 is a flowchart illustrating the operation of system 1 according to such an embodiment.

[0085] As shown in Figure 7, in one embodiment, the process of step S12 may be inserted between step S10 and step S20. That is, when displaying the software keyboard in step S10, if there is a character input area TA in the application display area AD, system 1 shrinks the application display area AD (step S20). On the other hand, when displaying the software keyboard in step S10, if there is no character input area TA in the application display area AD, system 1 does not shrink the application display area AD (skip step S20).

[0086] In the embodiment described above, the application display area AD is reduced in size to avoid obscuring the character input area TA when the software keyboard is displayed on the display unit 110 of the mobile client terminal 100 along with the application display area AD. On the other hand, if a hardware keyboard is connected to the mobile client terminal 100, it is conceivable that the mobile client terminal 100 will not display the software keyboard on the display unit 110. In such a case, system 1 does not need to reduce the application display area AD, and therefore may skip the operation in step S20.

[0087] Furthermore, in System 1 according to one embodiment, the content of the application display area AD displayed on the display unit 110 may differ not only depending on whether a hardware keyboard is connected, but also depending on whether a hardware mouse or trackball is connected. For example, depending on whether a hardware mouse or trackball is connected, a home screen (desktop screen) for PC work may be displayed on the display unit 110. Here, the home screen (desktop screen) for PC work may, for example, display the application display area AD with a different resolution than when the mobile client terminal 100 is normally operating. Also, on the home screen (desktop screen) for PC work, a taskbar or the like may be displayed in the application display area AD. Furthermore, when displaying the home screen (desktop screen) for PC work, for example, a pointer (a pointer displayed when operating a mouse) may be displayed in the application display area AD.

[0088] Furthermore, in the system 1 according to one embodiment, the content of the application display area AD displayed on the display unit 110 may differ depending on whether a relatively large display is connected and / or the orientation of the screen. Also, in the system 1 according to one embodiment, when the server 10 is accessed by a computer via multi-access, the content of the application display area AD displayed on the display unit 110 may not change. Also, in the system 1 according to one embodiment, the content of the application display area AD displayed on the display unit 110 may differ based on user operation or input.

[0089] Here, we will further explain the reduction of the application display area AD in Figures 6 and 7 (step S20).

[0090] Figure 8 is a flowchart that explains step S20 in Figures 6 and 7 in more detail. In other words, Figure 8 is a diagram that shows in more detail the operation and processing of shrinking the application display area AD in Figures 6 and 7.

[0091] When the operation shown in Figure 8 begins, the system 1 according to one embodiment determines whether the character input area TA overlaps with the software keyboard display area KD (step S21).

[0092] If the character input area TA does not overlap with the software keyboard display area KD in step S21, system 1 may terminate the operation shown in Figure 8. On the other hand, if the character input area TA overlaps with the software keyboard display area KD in step S21, system 1 moves the position of the character input area TA so that it does not overlap with the software keyboard display area KD (step S23).

[0093] Next, in one embodiment of the system 1, the application display area AD of the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100 is reduced in size (step S25).

[0094] The server 10 may generate data that constitutes such a screen after the software keyboard display area KD has been reduced in size or the position of the character input area TA has been moved, and send it to the mobile client terminal 100. As a result, the mobile client terminal 100, having received the screen data from the server 10, can display the reconfigured screen on the display unit 110.

[0095] After reconfiguring the display screen of the display unit 110 of the mobile client terminal 100, it is conceivable that the entire application display area AD may not be able to be displayed on the display unit 110. For example, considering its use as a mobile terminal, the mobile client terminal 100 is expected to have a relatively small screen size display unit 110. In such a case, if the application display area AD of the mobile client terminal 100 is reduced, it is conceivable that after reconfiguring the display area of ​​the display unit 110, only a part of the application display area AD will be displayed on the display unit 110. In such cases, enabling scrolling of the application display area AD may allow the user to manually move to the text input area TA. Alternatively, enabling scrolling of the application display area AD may allow the user to manually view the entire application display area AD. For example, in one embodiment, when the display screen of the display unit 110 is reconfigured, a scroll bar (knob and / or arrow) for scrolling the application display area AD may be displayed on the display unit 110.

[0096] The timing for shrinking the application display area AD may be as follows: For example, it may be when the server 10 requests the mobile client terminal 100 to enable the software keyboard, and the application display area AD sends / receives the screen area after the software keyboard has been displayed to the server 10. Alternatively, the server 10 may request / instruct the mobile client terminal 100 to enable / disable the software keyboard. Therefore, it may also be at the timing when the software keyboard is requested / instructed to enable / disable. At such a timing, the application display area AD may be reduced by referring to the information related to the software keyboard display area KD from the previous display, which has been stored in the server 10.

[0097] As described above, it is not necessary to send information related to the software keyboard display area KD from the mobile client terminal 100 to the server 10 every time the software keyboard is displayed. For example, information related to the software keyboard display area KD may be sent from the mobile client terminal 100 to the server 10 only when there is a change in the software keyboard display area KD.

[0098] Furthermore, in one embodiment, if, for example, the display position of the software keyboard display area KD is not fixed on the display unit 110, the application display area AD may not be changed. In this case, for example, information related to the keyboard display area KD may not be sent from the mobile client terminal 100 to the server 10. Also, for example, when sending information related to the keyboard display area KD from the mobile client terminal 100 to the server 10, information indicating whether or not the display position of the software keyboard display area KD is fixed on the display unit 110 may be included.

[0099] In this embodiment of System 1, the server 10 communicates with the mobile client terminal 100 via a network. Here, the server 10 generates data for the display screen of a virtual mobile client terminal corresponding to the mobile client terminal 100. The mobile client terminal 100 also includes a display unit 110. The display unit 110 displays the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100. Furthermore, in this embodiment of System 1, when displaying a software keyboard on the display unit 110 of the mobile client terminal 100, the application display area of ​​the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100 is reduced.

[0100] In one embodiment, the server 10 may generate display screen data in which the application display area of ​​the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100 has been reduced. In this case, the reduction of the application display area may be in accordance with the size of the display area of ​​the software keyboard displayed on the display unit 110. Alternatively, the server 10 may generate display screen data that includes the character input area in the application display area of ​​the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100.

[0101] In one embodiment, the mobile client terminal 100 may reduce the application display area of ​​the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100. In this case, the reduction of the application display area may be in accordance with the size of the display area of ​​the software keyboard displayed on the display unit 110.

[0102] In this case, if a hardware keyboard is connected to the mobile client terminal 100, the application display area of ​​the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100 may be kept from shrinking.

[0103] In order to perform the operation of System 1 according to the above embodiment, the server 10 and / or mobile client terminal 100 may each perform the following operations.

[0104] For example, the mobile client terminal 100 may transmit keyboard area information related to the area on the display unit 110 where a software keyboard is displayed to the server 10. Based on the keyboard area information, the server 10 may generate display screen data in which the application display area is outside the area where the software keyboard is displayed. Alternatively, for example, the mobile client terminal 100 may transmit display area information related to the display area of ​​the display unit 110 to the server. The server 10 may receive display area information from the mobile client terminal 100. The mobile client terminal 100 may transmit application area information related to the area on the display unit 110 corresponding to the application display area to the server along with the keyboard area information. The server 10 may receive application area information along with the keyboard area information from the mobile client terminal.

[0105] Furthermore, for example, if the character input area in the application display area of ​​the display screen of a virtual mobile client terminal corresponding to the mobile client terminal 100 overlaps with the area of ​​the software keyboard displayed on the display unit 110, the following may be done: In this case, the server 10 may move the character input area to a position where it does not overlap with the area of ​​the software keyboard. Alternatively, in this case, the mobile client terminal 100 may move the character input area to a position where it does not overlap with the area of ​​the software keyboard.

[0106] Furthermore, for example, the mobile client terminal 100 may transmit to the server 10 display area information related to the display area of ​​the display unit 110, and keyboard area information related to the area on the display unit 110 where a software keyboard is displayed. Based on the display area information and keyboard area information, the server 10 may reduce the application display area of ​​the display screen of the virtual mobile client terminal corresponding to the mobile client terminal 100.

[0107] According to system 1 of one embodiment, the user of the mobile client terminal 100 can avoid a situation where, for example, when the software keyboard is displayed on the display unit 110, the character input area TA is hidden by the software keyboard. Therefore, the user of the mobile client terminal 100 can input strings of characters using the software keyboard while visually viewing the character input area.
