     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0038]    Generally, user friendly with the operation interface of an electronic product is important to a consumer. Especially, with a portable electronic device, a user is annoyed in bringing additional input devices, for example, a keyboard, or a stylus. Users are more satisfied with a touch screen disposed on the electronic product to achieve all operation by fingers. Thus, it is important for manufacturers to develop a mechanism which allows the user to operate applications in the electronic product with the touch screen directly. The invention provides a method and an electronic device based on the view above. These and other features, aspects and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings. 
         [0039]      FIG. 1  is a block diagram showing the electronic device in an embodiment of the invention. As shown in  FIG. 1 , the electronic device  100  includes a touch screen  110 , a touch time determining module  120  and an operating module  130 . The electronic device  100  may be a mobile phone, a personal digital assistant (PDA), a smart phone, a tablet personal computer or one of other kinds of electronic products, which is not limited. The functions of components in the electronic device  100  are illustrated herein. 
         [0040]    In the embodiment, the touch screen  110  may be a resistance-type touch screen or a capacitance-type touch screen. The touch screen  110  may support various functions of operation, and it also may receive touch signal performed by the user with an input tool such as a finger or a touch pen. 
         [0041]    The touch time determining module  120  is connected to the touch screen  110 , and it is used to determine whether the touch signal is a trigger signal. In the embodiment, the trigger signal is a long-keeping signal which keeps still at a location on the touch screen in a preset time. The location may be any position on the touch screen  110 , and the preset time is not limited. Preferably, the preset time may be between 0.2 seconds to 0.5 seconds. In the embodiment, the touch time determining module  120  may be hardware, software having calculating ability or the combination of the software and the hardware, and the mode of realizing the touch time determining module  120  is not limited herein. 
         [0042]    The operating module  130  is connected to the touch screen  110  and the touch time determining module  120 . According to the determining result generated by the touch time determining module  120 , the operating module  130  determines if the page displayed on the touch screen  110  should be operated according to the moving track. The operating module  130  may be the hardware or software having controlling and processing ability or their combination, and the mode of realizing the operating module  130  is not limited herein. 
         [0043]    The flow path of operating the electronic device  100  in the invention is illustrated herein.  FIG. 2  is a flow chart showing the method for operating the page in an embodiment of the invention. As shown in  FIG. 1  and  FIG. 2 , in the embodiment, a page is displayed by the touch screen  110 , and the page may be a web browser page, an image browser page, a file browser page or a document browser page, which is not limited. In other words, after the user starts different browser application in the electronic device  100 , the content displayed via the browser application (such as web pages, images, files or documents) may be shown via the touch screen  110 . 
         [0044]    When the user starts to operate the page displayed on the touch screen  110 , he or she may use a finger or a proper input tool to touch the touch screen  110  to generate a touch signal. As shown in step  210 , the touch screen  110  may receive the corresponding touch signal. Then, the electronic device  100  determines the touch signal to actuate the touch control functions. In step  220 , the touch time determining module  120  determines whether the touch signal is a trigger signal of operating a page. In the embodiment, the trigger signal is a long-keeping signal which keeps still at a location on the touch screen  110  in a preset time (such as 0.5 seconds). In the embodiment, the touch time determining module  120  may start to count the time after the touch screen receives the touch signal. If the user moves his or her finger or the input tool away from the touch screen  110  before the preset time is reached, the flow path of the method for operating the page is finished. That is, to actuate the touch control functions is failed. 
         [0045]    However, if the time counted by the touch time determining module  120  reaches the preset time, and the user moves the finger or the proper input tool to generate a track sequentially on the touch screen  110 , as shown in step  230 . The operating module  130  captures the moving track, and in step  240 , the page is performed with an operation according to the type of the moving track. Furthermore, the operating module  130  may obtain the gesture and direction of the moving track and operate the page correspondingly. 
         [0046]    As shown in the steps in  FIG. 2 , only when the time for which the touch signal on the touch screen  110  reaches the preset time, the operating module  130  may operate the page according to the moving track of the touch signal. The step of determine the lasting time of touching ensures that the operating module  130  does not react unintentionally, and this prevents the electronic device  100  from executing a mis-operation of the user. 
         [0047]    How the operating module  130  operates the page correspondingly according to the gesture and direction of the moving track is illustrated hereinbelow. 
         [0048]    In an embodiment, when the touch screen  110  receives the touch signal, and the touch time determining module  120  determines whether the touch signal is the trigger signal, and the operating module  130  is subsequently determined whether the touch screen  110  displays the page completely. That is, the operating module  130  determines if the whole content of the page is completely displayed on the touch screen  110  according to the size of the page and the size of the touch screen  110 , then, the operate module  130  operates the page according to the determining result and the moving track of the touch signal. 
         [0049]    Different types of the moving track correspond to various default operations in the electronic device  100 . The first type of the moving track is a linear track or a curved track, however, there is not limited in the shape of tracks. When the moving track is the first type, the operating module  130  may obtain the moving direction corresponding to the moving track, and pages are operated and displayed according to different moving directions. Supposing that the first type of track preset by the electronic device  100  is the linear track, the operating module  130  may switch the page to next page when the moving track is the linear track and the moving direction is left, and it may switch the page to the previous page if the moving direction is right. The start point of the moving track may be the same as or different from the position of the location. That is, when the time for which the user&#39;s touch reaches the preset time, the moving track is thus determined from the location sequentially or another position with the finger or input tools, which is not limited. 
         [0050]    For example, when the size of the page is full screen on the touch screen  110 , as shown in  FIG. 3A  and  FIG. 3B , the user may operate the page with a finger. As shown in  FIG. 3A , if the user touches the location  310  of the touch screen  110  and it is determined as a long-keeping signal, i.e. the trigger signal, the operating module  130  may switch the page to the previous page when the user moves the finger towards left horizontally. As shown in  FIG. 3B , if the user touches the location  310  of the touch screen  110  and it is determined as a long-keeping signal, i.e. the trigger signal, the operating module  130  may switch the page to the next page when the user moves the finger towards right horizontally. To the user, the operation mode rather is the habit of turning pages when he or she reads a book, and it is intuitive and convenient. 
         [0051]    Moreover, when the touch screen  110  only displays part area of the page, the user may operate the page to display full page by the following process. First of all, the operating module  130  obtains the moving direction corresponding to the moving track, and determines the direction of the moving direction by comparing with the default directions, i.e. to determine which default direction is the closest to the moving direction. At last, the page is moved according to the determined default direction to adjust the page displayed on the touch screen  110 . 
         [0052]      FIG. 4  is a schematic diagram showing the operation of the page by moving the finger. As shown in  FIG. 4 , when the page  410  showed on the touch screen  110  is over-sized, and the moving track determined by the electronic device  100  is the linear track, the operating module  130  may determine which default, direction is the most closest to the moving direction corresponding to the linear moving track. The default directions are not limited but preferably are up, down, left, right, upper left, lower left, upper right and lower right and the like. Following the process above, the page  410  is moved according the determined closest default direction, and this allows the user to move the page  410  by finger directly and browse the whole page  410 . 
         [0053]    In another embodiment, when the moving track corresponding to the touch signal is the second type of track, the operating module  130  rotates the page towards the moving direction. In the preferred embodiment, the second type of track is a circular curved track, as shown in  FIG. 5A . When the long-keeping signal is determined on the location  510 , and the moving track is clockwise-circular curve, the operating module  130  may rotate the page by default angles (such as 90 degrees) clockwise. As shown in  FIG. 5B , if the long-keeping signal is determined and the moving track is anti-clockwise, the operating module  130  may rotate the page anti-clockwise correspondingly. Thus, the user may rotate the page to make it suitable for watching. 
         [0054]    In still another embodiment, after the touch is determined as long-keeping signal, the operating module  130  then determines whether another touch signal is received by the touch screen  110 . (The position from which the touch signal is received again may be the same with or different from the position of the location.) If the touch screen  110  receives the touch signal again, the operating module  130  may capture the moving track formed by the second touch signal and determine if the moving track is the third type of track. When the moving track is the third type of track, the page is zoomed in or out corresponding to the moving track. The operating module  130  may determine the zooming ratio according to the length of the moving track, and the third type of track is default in the electronic device  100 . The third type of track includes a linear track or a curved track, and the invention is not limited thereto. 
         [0055]    As shown in  FIG. 6A , supposing that the third type of track is the curved track, and the long-keeping signal is determined on the location  610 , when the clockwise curve is drawn by the user at the position near the location  610  on the touch screen  110 , the operating module  130  performs zooming in on the page therewith. Furthermore, if the touch signal is determined as trigger signal as shown in  FIG. 6B , when the anti-clockwise curve is drawn by the user at the position near the location  610  on the touch screen  110 , the operating module  130  performs zooming out on the page. 
         [0056]    Beside the embodiments described above, the trigger signal can be any default actions on the touch screen, such as continuously-tapping in a preset time or any specific gestures. For example, if the touch on the touch screen  110  is determined as continuously-tapping signal, the operating module  130  then determines whether another touch signal is received by the touch screen  110 , and performs page operations accordingly. In the preferred embodiment, the preset time for determine the continuously-tapping signal as trigger signal may between 0.2 seconds to 0.5 seconds. However, the preset time for determine the trigger signals is not limited in the present invention. 
         [0057]    In the above embodiment, various of page operations are corresponding to the moving tracks of the touch signal, and thus, if the touch time determining module  120  determines that the touch signal on the touch screen  110  is the trigger signal, the operating module  130  may subsequently determine the type of the moving track and the moving direction, and the corresponding page operations is then performed. 
         [0058]    In the preferred embodiment as described above, the type of the moving tracks, the moving directions and the page operating actions are all taken as examples, and the invention is not limited thereto. In addition, the operations such as rotating, moving, zooming in, zooming out, and adjusting pages can be performed in not only the content of the page inside a frame but also the entire page within the frame and the content the page. 
         [0059]    To sum up, the present invention provides a method for operating the page on the electronic device with touch screen without mis-operation by users. In the present invention, if the user wants to move, switch, rotate, zoom in or zoom out of the page displayed on the touch screen, a trigger signal should be determined first and the following moving tracks corresponding to the touch signal is then determined, and the operations can be performed accordingly. Thus, the user may perform various page operations via simple touch signal, and the mis-operation due to the over-quick reaction or mis-touched of the touch screen is also prevented. 
         [0060]    Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope of the invention. Persons having ordinary skill in the art may make various modifications and changes without departing from the scope and spirit of the invention. Therefore, the scope of the appended claims should not be limited to the description of the preferred embodiments described above.
