FIG. 1 is a block diagram of one embodiment of a hand-held electronic device 1 comprising a focusing system 10. In some embodiments, the hand-held electronic device 1 may be a mobile phone, for example. The hand-held electronic device 1 includes a display screen 11. The display screen 11 displays a plurality of icons of software applications of the hand-held electronic device 1. For example, the icons may include a browser icon, a message icon and a setting icon. The icons can be created or deleted by users. In one embodiment, the display screen 11 may be a touch screen. The hand-held electronic device 1 includes navigation keys 12. The navigation keys 12 include an up/down-arrow key and a left/right-arrow key. The up/down-arrow key includes an up-arrow key and a down-arrow key. The left/right-arrow key includes a left-arrow key and a right-arrow key.
In an exemplary embodiment, the hand-held electronic device 1 includes at least one processor 13 and a storage system 14. The focusing system 10 may include one or more modules (also described in FIG. 2). The one or more modules may comprise computerized code in the form of one or more programs that are stored in the storage system 14 (or memory). In one embodiment, the storage system 14 may be a magnetic, an optical storage system, or other suitable storage medium. The computerized code includes instructions that are executed by the at least one processor 13 to provide functions for the one or more modules described below. The storage system 14 stores an information table. The information table includes a name column, a use times column, and a use time column, as shown in FIG. 6. Each value of the use times column indicates how many times that the icon has been used. Each value of the use time column indicates the last time that an icon was used.
As shown in FIG. 2, the focusing system 10 may include a determination module 100, an execution module 101, a detection module 102, and an updating module 103.
When the display screen 11 is displaying the icons, the determination module 100 determines if the up/down-arrow key or the left/right-arrow key of the hand-held electronic device 1 have been operated by a user.
If the up/down-arrow key has been operated, the execution module 101 focuses an icon according to an operation direction of the up/down-arrow key and a use times of each icon. In some embodiments, the execution module 101 focuses the icon by highlighting the icon with a graphic (such as a rectangle) or a color.
In one embodiment, the execution module 101 detects if the up-arrow key or the down-arrow key has been operated. If the up-arrow key has been operated, the execution module 101 detects if an icon is being focused. If an icon is being focused, the execution module 101 refreshes the information table according to the use times of each icon. In one embodiment, the use times appears from a minimum value to a maximum value. The execution module 101 determines, in the information table, a next icon having a use times that is more than the use times of the icon being focused, and focuses the next icon. If no icon is being focused, the execution module 101 determines an icon having a use times with the maximum value in the information table, and focuses the determined icon.
If the down-arrow key has been operated and an icon is being focused, the execution module 101 determines a prior icon having a use times that is less than the use times of the focused icon in the information table, and focuses the determined prior icon. If the down-arrow key has been operated and no icon is being focused, the execution module 101 determines an icon having a use times with the minimum value in the information table, and focuses the determined icon.
For example, as shown in FIG. 6, the value of the use times of the icon “browser” is at the maximum, and the value of the use times of the icon “message” is at the minimum. If no icon is being focused and the up-arrow key has been operated, the execution module 101 focuses the icon “browser.” If no icon is being focused and the down-arrow key has been operated, the execution module 101 focuses the icon “message.” If the icon “browser” is focused and the down-arrow key has been operated, the execution module 101 determines that the next icon is the icon “setting” in the information table, and focuses the icon “setting.”
If the left/right-arrow key has been operated, the execution module 101 calculates a time difference between each use of each icon in the information table by reference to a first current system time of the hand-held electronic device 1. The execution module 101 determines an icon according to the time difference and the operated left/right-arrow key.
For example, the execution module 101 detects if the left-arrow key or the right-arrow key has been operated. If the left-arrow key has been operated, the execution module 101 sorts the calculated time differences in sequence. The sequence may be from the maximum value to the minimum value. The execution module further determines an icon corresponding to the minimum value of the time difference, and focuses the determined icon. If the right-arrow key has been operated, the execution module 101 determines a prior value before the minimum value, and focuses an icon corresponding to the determined prior value.
The detection module 102 detects if the focused icon is clicked by the user. If the focused icon is clicked, the updating module 103 adds one to the value of the use times corresponding to the focused icon, and records the time of use of the focused icon according to a second system time of the hand-held electronic device 1, in the information table.
FIG. 3 is a flowchart illustrating a method for focusing icons of a hand-held electronic device. Depending on the embodiment, additional steps may be added, others removed, and the ordering of the blocks may be changed.
In step S30, the determination module 100 determines if the up/down-arrow key or the left/right-arrow key of the hand-held electronic device 1 have been operated when the display screen 11 is displaying the icons. If the user operates the up/down-arrow key, step S31 is implemented. If the user operates the left/right-arrow key, step S32 is implemented.
In step S31, the execution module 101 focuses an icon according to an operation direction of the up/down-arrow key and use times of each icon. The operation direction includes up direction and down direction.
In step S32, the execution module 101 calculates a time difference between the present use of each icon and the most recent past use in the information table by reference to a first current system time of the hand-held electronic device 1.
In step S33, the execution module 101 focuses an icon according to the time differences and an operation direction of the left/right-arrow key. The operation direction of the left/right-arrow key includes left direction and right direction.
In step S34, the detection module 102 detects if the focused icon is clicked by the user. If the user has clicked the icon, step S35 is implemented. If the user has not clicked the icon, step S30 is repeated.
In step S35, the updating module 103 adds one to the value of the use times corresponding to the focused icon, and records the present time of use of the focused icon by reference to a second system time of the hand-held electronic device 1, in the information table.
FIG. 4 is a detail flowchart illustrating step S31 of FIG. 3. Depending on the embodiment, additional steps may be added, others removed, and the ordering of the steps may be changed.
In step S310, the execution module 101 detects if the up-arrow key or the down-arrow key has been operated. If the up-arrow key has been operated, step S311 is implemented. If the down-arrow key has been operated, step S315 is implemented.
In step S311, the execution module 101 detects if an icon is being focused. If an icon is being focused, step S312 is implemented. If no icon is being focused, step S314 is implemented.
In step S312, the execution module 101 refreshes the information table according to the use times of each icon, and determines a next icon having a use times that is more than the use times of the focused icon.
In step S313, the execution module 101 focuses the determined icon.
In step S314, the execution module 101 determines an icon having a use times with the maximum value in the information table, and step S313 as described above is implemented.
In step S315, the execution module 101 detects if an icon is being focused. If an icon is being focused, step S316 is implemented. If no icon is being focused, step S317 is implemented.
In step S316, the execution module 101 determines a prior icon having a use times that is less than use times of the focused icon, and step S313 as described above is implemented.
In step S317, the execution module 101 determines an icon having a use times with the minimum value in the information table, and step S313 as described above is implemented.
FIG. 5 is a detail flowchart illustrating step S33 of FIG. 3. Depending on the embodiment, additional steps may be added, others removed, and the ordering of the steps may be changed.
In step S330, the execution module 101 detects if the left-arrow key or the right-arrow key has been operated. If the left-arrow key has been operated, step S331 is implemented. If the right-arrow key has been operated, step S333 is implemented.
In step S331, the execution module 101 sorts the calculated time differences in sequence, and determines an icon corresponding to the minimum value of the time differences.
In step S332, the execution module 101 focuses the determined icon.
In step S333, the execution module 101 determines a prior value before the minimum value, determines an icon corresponding to the determined prior value, and step S332 as described above is implemented.
Although certain inventive embodiments of the present disclosure have been specifically described, the present disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the present disclosure without departing from the scope and spirit of the present disclosure.
