In the present exemplary embodiment, the rearrangement event monitoring module 210 is configured at the application layer 200a, and the window management module 220 and the activity management module 230 are configured at the frameworks layer 200b. 
FIG. 2 is a schematic block diagram illustrating a multi-window arrangement system according to an exemplary embodiment of the invention.
Referring to FIG. 2, the quick multi-window arrangement system 200 includes a rearrangement event monitoring module 210, a window management module 220 and an activity management module 230. It is to be mentioned that in the present exemplary embodiment, the rearrangement event monitoring module 210, the window management module 220 and the activity management module 230 are implemented in a software form. However, the invention is not limited thereto, and in another exemplary embodiment, the rearrangement event monitoring module 210, the window management module 220 and the activity management module 230 may be implemented in a hardware form.
The rearrangement event monitoring module 210 is configured to monitor a window arrangement driving event at the application layer 200a. 
The window management module 220 is coupled to the rearrangement event monitoring module 210 and configured to manage a plurality of window objects operated by the mobile apparatus 100. The window management module 220 includes a multi-window mode controller module 222, an application window object module 224 and a window setting module 226. The application window object module 224 is configured to manage all window objects 228(0) to 228(n) operated by the mobile apparatus 100. The window setting module 226 is configured to arrange the window objects 228(0) to 228(n).
To be more specific, when monitoring a window arrangement driving event, the rearrangement event monitoring module 210 transfers the window arrangement driving event from the application layer 200a to the frameworks layer 200b. When the window arrangement driving event is received at the frameworks layer 200b, the multi-window mode controller module 222 is configured to identify a current arrangement mode of the window objects currently operated by the mobile apparatus 100 and select a new arrangement mode according to the current arrangement mode. Additionally, the multi-window mode controller module 222 obtains all the window objects 228(0) to 228(n) currently operated on the mobile apparatus 100 from the application window object module 224 and calculate a display position and a display size for each of the obtained window objects according to the new arrangement mode.

For example, the fixed region 102b contains a return key 302, a home key 304 and a multi-task key 306 on a default system bar, and thus, deploying the key 300 on the system bar in the fixed region 102b causes the least affection to the original system and user interface.
For example, the window arrangement modes include a side-by-side mode, a 4-grid mode and a cascade mode. Nevertheless, it should be understood that the invention is not limited thereto, and the window arrangement mode may also be any other suitable mode. In the present exemplary embodiment, the multi-window mode controller module 222 is configured to check the current window arrangement mode. If the current window arrangement mode is the side-by-side mode, the multi-window controller module 222 sets the new arrangement mode to be the 4-grid mode. If the current window arrangement mode is the 4-grid mode, the multi-window controller module 222 sets the new arrangement mode to be the cascade mode. If the current window arrangement mode is the cascade mode, the multi-window controller module 222 sets the new arrangement mode to be the side-by-side mode.
FIGS. 4A to 4C are schematic diagrams illustrating the automatic arrangement method performed of the side-by-side mode according to an exemplary embodiment of the invention.
FIGS. 4A to 4C illustrates a scenario where after the window arrangement driving event is received at the frameworks layer 200b, the multi-window mode controller module 222 identifies that the current arrangement mode of all the window objects currently operated by the mobile apparatus 100 is the cascade mode and selects the side-by-side mode as the new arrangement mode according to the current arrangement mode.
Referring to FIG. 4A, in a non-automatic arrangement state (as shown at the left side), the window object currently operated on the mobile apparatus 100 and obtained from the application window object module 224 by the multi-window mode controller module 222 is the window object 228(0), and the multi-window mode controller module 222 calculates a display position and a display size for the obtained window object 228(0) according to the new arrangement mode (i.e., the side-by-side mode). Then, the window setting module 226 arranges the window object 228(0) according to the calculated display position and display size. Since the number of the window objects obtained from the application window object module 224 is only one, the arranged window object 228(0) is located at the left of the touch screen 102 in a way that a window object 228′(0) is in an automatic arrangement state (as shown at the right side).
Referring to FIG. 4B, in the non-automatic arrangement state (as shown at the left side), the window objects currently operated on the mobile apparatus 100 and obtained from the application window object module 224 by the multi-window mode controller module 222 are the window objects 228(0) and 228(1), and the multi-window mode controller module 222 calculates display positions and display sizes for the obtained window objects 228(0) and 228(1) according to the new arrangement mode (i.e., the side-by-side mode). Then, the window setting module 226 arranges the window objects 228(0) and 228(1) according to the calculated display positions and display sizes. The arranged window objects 228(0) and 228(1) are arranged side by side on the touch screen 102 in a way that window objects 228′(0) and 228′(0) are in the automatic arrangement state (as shown at the right side).
Referring to FIG. 4C, in the non-automatic arrangement state (as shown at the left side), the window objects currently operated on the mobile apparatus 100 and obtained from the application window object module 224 by the multi-window mode controller module 222 are the window objects 228(0) to 228(2), and the multi-window mode controller module 222 calculates display positions and display sizes for the obtained window objects 228(0) to 228(2) according to the new arrangement mode (i.e., the side-by-side mode). Specially, since the number of window objects obtained from the application window object module 224 is 3. The foreground task setting module 232 sequentially display the window objects 228(0) to 228(2) on the foreground of the mobile apparatus 100 according to an execution sequence of the window objects 228(0) to 228(2) and only displays the two latest operated window objects according to the side-by-side mode. That is, as shown in the automatic arrangement state (as shown at the right side), the latest operated window objects 228′(0) and 228′(1) are separated and arranged side by side on the touch screen 102 in a way that window objects 228′(0) and 228′(0) are in the automatic arrangement state (as shown at the right side). In this case, the latest operated window object 228′(0) is set as an active window, but the invention is not limited thereto.
It is to be mentioned that in the side-by-side mode, the two window objects are symmetrically arranged on the left and the right on the screen by the multi-window arrangement system, and thus, the user may quickly operate two applications provided by the two window objects simultaneously, without additionally switching the windows. When the number of the window objects viewable on the screen is more than 2, two latest operated window objects used by the user is displayed on the touch screen by the multi-window arrangement system. Specially, with the side-by-side mode, the user may conveniently operate and view the two applications. For example, while starting a browser to surf shopping information on a website, the user may open a map application to search for a shop position or may receive email while looking up data.
FIGS. 5A to 5E are schematic diagrams illustrating the automatic arrangement method performed of the 4-grid mode according to an exemplary embodiment of the invention.
FIGS. 5A to 5E illustrates a scenario where after the window arrangement driving event is received at the frameworks layer 200b, the multi-window mode controller module 222 identifies that the current arrangement mode of all the window objects currently operated by the mobile apparatus 100 is the side-by-side mode. Thus, according to the current arrangement mode, the 4-grid mode is selected as the new arrangement mode. The automatic arrangement method of the 4-grid mode is similar to that of the side-by-side mode, and they are different from each other in that in the 4-grid mode, the arranged window objects are separated in four blocks, i.e., the upper left, the upper right, the lower left and the lower right, on the touch screen 102, and the four block do not overlap with one another. Therefore, the automatic arrangement method of the 4-grid mode is not repeatedly described hereinafter.
It is to be mentioned that in the 4-grid mode, the user may simultaneously operate applications provided by four window objects. The mode is applicable to a scenario where the user needs to simultaneously operate 3 to 4 applications, and a display size required by each of the applications is not large.
FIGS. 6A to 6D are schematic diagrams illustrating an automatic arrangement of the cascade mode according to an exemplary embodiment of the invention.
FIGS. 6A to 6D illustrates a scenario where after the window arrangement driving event is received at the frameworks layer 200b, the multi-window mode controller module 222 identifies that the current arrangement mode of all the window objects currently operated by the mobile apparatus 100 is the 4-grid mode. Thus, according to the current arrangement mode, the cascade mode is selected as the new arrangement mode.
Referring to FIG. 6A, in a non-automatic arrangement state (as shown at the left side), the window object currently operated on the mobile apparatus 100 and obtained from the application window object module 224 by the multi-window mode controller module 222 is the window object 228(0), and the multi-window mode controller module 222 calculates a display position and a display size for the obtained window object 228(0) according to the new arrangement mode (i.e., the cascade mode). Then, the window setting module 226 arranges the window object 228(0) according to the calculated display position and display size. Since the number of the window objects obtained from the application window object module 224 is only one, the arranged window object 228(0) is located in the center of the touch screen 102 in a way that a window object 228′(0) is in an automatically arranged state (as shown at the right side).
Referring to FIG. 6B, in the non-automatic arrangement state (as shown at the left side), the window objects currently operated on the mobile apparatus 100 and obtained from the application window object module 224 by the multi-window mode controller module 222 are the window objects 228(0) and 228(1), and the multi-window mode controller module 222 calculates display positions and display sizes for the obtained window objects 228(0) and 228(1) according to the new arrangement mode. Then, the window setting module 226 arranges the window objects 228(0) and 228(1) according to the calculated display positions and display sizes. Specially, in the cascade mode, the calculated display size of each of the window objects is set to be the same, and namely, the calculated display sizes of the window objects 228(0) and 228(1) are the same. Additionally, the foreground task setting module 232 sequentially displays the window objects 228(0) to 228(1) on the foreground of the mobile apparatus 100 according to an execution sequence of the window objects 228(0) to 228(1) and displays by stacking the window object 228(0) on the window object 228(1) from the lower right to the upper left on the screen of the touch screen 102 according to the execution sequence. That is, the arranged window objects 228(0) and 228(1) are arranged in a way that window objects 228′(0) and 228′(1) are in the automatically arranged state (as shown at the right side).
FIG. 6C illustrate a scenario where the number of the window objects currently operated on the mobile apparatus 100 and obtained by the multi-window mode controller module 222 is 4, and FIG. 6D illustrates a scenario of 5. The automatic arrangement methods illustrated in FIGS. 6C and 6D are similar to the automatic arrangement method for two window objects illustrated in 6B and will not repeated hereinafter.
FIGS. 7A and 7B are flowcharts illustrating a method for quickly arranging multiple windows according to an exemplary embodiment of the invention.
Referring to FIG. 7A, in step S701, the rearrangement event monitoring module 210 monitor a window arrangement driving event at the application layer, where the window arrangement driving event is triggered by a key displayed on the touch screen.
In step S703, when the window arrangement driving event is generated, the rearrangement event monitoring module 210 transfers the window arrangement driving event from the application layer to the frameworks layer.
Then, in step S705, when the window arrangement driving event is received at the frameworks layer, the multi-window mode controller module 222 identifies a current arrangement mode and selects a new arrangement mode according to the current arrangement mode.
Referring to FIG. 7B, FIG. 7B illustrates a method for selecting the new arrangement mode in step S705 of FIG. 7A. In step S705, the multi-window mode controller module 222 checks the current window arrangement mode. If the current window arrangement mode is the side-by-side mode, the multi-window controller module 222 sets the new arrangement mode to be the 4-grid mode (Step S705a). If the current window arrangement mode is the 4-grid mode, the multi-window controller module 222 sets the new arrangement mode to be the cascade mode (step S705b). If the current window arrangement mode is the cascade mode, the multi-window controller module 222 sets the new arrangement mode to be the side-by-side mode (step S705c).
Referring to FIG. 7A again, in step S707, the multi-window mode controller module 222 obtains all the window objects currently operated on the mobile apparatus. Then, in step S709, the multi-window mode controller module 222 calculates a display position and a display size for each of the obtained window objects according to the new arrangement mode.
Thereafter, in step S711, the window setting module 226 arranges each of the window objects according to the display position and the display size thereof.
