Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a touch screen method and device, and in particular, relates to a touch screen unlocking method and device. 
       BACKGROUND 
       [0002]    Touch screen devices are mainstream electronic products in the prior art, having a rich variety of unlocking methods, which may basically utilize a way of slide-to-unlock, such as sliding from left to right or from right to left in a straight line, or drawing a multi-point connecting line, or lining out an icon from a designated area. All these methods belong within the scope of slide-to-unlock. 
         [0003]    Slide-to-unlock has its drawbacks due to the fact that a device may not determine a sliding path correctly, for instance, it may be hard to control the length of a sliding path or the force exerted on the sliding path. There appears to be no technical solution in the prior art using two-point touches to unlock a screen; therefore, there is much room for the prior art to be improved and developed. 
       SUMMARY OF THE INVENTION 
       [0004]    An object of the present invention is to provide a touch screen unlocking method and device, to provide an unlocking operation method not in a slide-to-unlock way, so as to achieve a more accurate unlocking operation, and reduce poor user experience caused by mistakes.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0032]    Embodiments of the present invention will be described in detail below. 
         [0033]    The unlocking method in an embodiment of a touch screen unlocking method and device according to the present invention may be similar to a simple game named “LinkGame”, which may achieve matching operation by tapping two points on a touch screen to conduct the determination and operation of unlocking or not unlocking. 
         [0034]    As shown in  FIG. 1 , a touch screen unlocking method and device of the present invention, may include a lock screen interface of a touch screen device that may be brightened by a tap, there may be a plurality of icons displayed in a random area on the screen, among which each kind of icon may have two matching icons displayed randomly in the area. When one of the two matching icons is tapped by a user, the other matching icon may be treated in a special way such as being magnified and displaced. The device can then be unlocked after the magnified icon is tapped by the user, or a predefined function can be directly started. The plurality of icons may not be limited to a display mode with random distribution but the icons can be preset to fixed locations. 
         [0035]    A correlation match between two points on a touch screen can be achieved by clicking two icons in sequence, thus performing unlocking. A matching icon may be magnified on the screen automatically after one of the matching icons is tapped, which can further facilitate the user&#39;s unlocking operation, thus improving the user experience. 
         [0036]    In an embodiment of a touch screen unlocking method and device of the present invention, after a user taps an icon, he or she may need to find out which icon matches the tapped icon from many icons displayed in a disorganized order. The user may continue to tap the icon to achieve unlocking. It may take a longer time for the user to find out the other matching icon on a screen of a large screen device with too many icons. Accordingly, the time for unlocking the device may increase, which may degrade the user&#39;s experience. However, while the user taps an icon, if an icon matching the icon is immediately magnified or displayed in other ways such as but not limited to highlighting, it may be very easy for the user to find an icon that matches the icon and tap it, thus reducing the time for the user to unlock the device. 
         [0037]    Prompting a user may not be limited by a touch screen unlocking method and device of the present invention. As shown in  FIG. 1 , there may be four groups of the matching icons. When a first selected icon  110  “five stars” is tapped by a user, a matching icon  120  may be magnified and displayed immediately by the operation program of the device to reduce the time spent in finding out the target icon by the user. 
         [0038]    Unlocking icons may not be limited by a touch screen unlocking method and device of the present invention as long as it can lead the user to tap two points on a screen in sequence.  FIG. 2  shows the processing flow of unlocking by tapping two points according to a method of the present invention, which comprises: providing multiple groups of icons on an unlocking interface, among which at least one group having two matching icons is arranged; waiting for a user to tap one of the two matching icons, and each of the icons can be set as having a matching icon, so that the user can tap any of the icons; determining and magnifying a matching icon in the list after one of the two matching icons is tapped by the user to prompt the user to note the magnified icon, and waiting for further user operation. If the user does not tap the touch screen, after a preset time such as 10 second, 20 seconds or 30 seconds, the state of the unlocking interface may be returned back to its initial state which waits for the user to tap the first selected icon. 
         [0039]    If the user performs a proper tap, unlocking the screen and clearing the recorded user tapping records are performed by the touch screen device to close the unlocking process. 
         [0040]    Function icons on a lock screen interface can be icons predefined by a system, and may also be icons customized by the user, which may not be specifically limited by the present invention as long as the displayed icons can be identified by the user. In an embodiment of the present invention, the displayed location of an icon may not be limited specifically as long as the user can touch the icon successfully. And the overall displayed shape and sequence of all the function icons may not specifically be limited either. The overall displayed shape of the icons can be in, for instance, a rectangle area or a circular area, and the displayed order of the icons can be in a random or a predefined way. 
         [0041]    In a touch screen unlocking device according to the present invention, the information such as a serial number of an icon, location of the icon, state of the icon as well as a serial number of an icon matching the icon may be stored in a configuration list. An unlocking program may read the information such as location, and state of the icon from the configuration list and may display the icon on the screen. When one icon is tapped by a user, the unlocking program may find out the icon from the icon configuration list, look up the information such as location, state of an icon that matches the icon, and magnify the other icon that matches the icon; the entire magnified area can effectively receive a tap from the user. 
         [0042]    In an embodiment of the present invention, a user can perform an editing operation to the unlocking icons on a lock screen interface such as adding or deleting icons. When the user adds new icons to the lock screen interface, two matching icons can be added at the same time to the lock screen interface to match each other, and similarly, the deleting operation can delete two matching icons at the same time. The information of the added icons may be stored in the configuration list, the information of the deleted icons may be deleted from the configuration list, and the added icons or the deleted icons may include matching icons. As a number of new functions for icons may be added by the user, the present invention is not specifically limited to a single icon function. 
         [0043]    In an embodiment, a touch screen unlocking method and device of the present invention shown in  FIG. 3 , can extend the function of unlocking by tapping two points. Considering that a user needs to access a corresponding application interface immediately after the lock screen interface, some application icons can be preset on the unlocking interface as quick start applications. Matching icons for unlocking can be set on the unlocking interface randomly, such as a camera icon and a music player icon shown in  FIG. 3 . The user can select an application expected to correspond to a first selected icon  111 , and can perform the second tap after the matching icon  121  is magnified and displayed; when the two icons tapped by the user match each other, the predefined function or application corresponding to the icon is started, and by doing so the user can access the corresponding application interface directly and quickly. The function extension of tapping two points to unlock the screen falls into the protective scope of the present invention. 
         [0044]    A touch screen unlocking method and device of the present invention may facilitate a user&#39;s operation, increase the user&#39;s operation accuracy, and improve user experiences accordingly. 
         [0045]    It should be understood that improvements or variations can be made according to the above description by those skilled in the art, and any of these improvements or variations may fall into the protective scope of claims appended to the present invention.
