The exemplary embodiment(s) of the present invention relates to a field of screen unlocking method. More specifically, the exemplary embodiment(s) of the present invention relates to a screen unlocking method for unlocking the screen of an electronic apparatus having a touch-controlled display.
The conventional touch-controlled screen unlocking method unlocks a touch-controlled screen by firstly touching a specific icon shown on the touch-controlled screen then dragging the icon with a limited direction and distance, and then the screen saving image disappears and a common working desktop is shown on the touch-controlled screen. Please refer to
However, the desktop is completely covered by the conventional screen saving image. Thus, the screen still needs to be unlocked by a limited mode when the user wants to view some parts of the desktop, and this causes inconvenience and less interesting for the user using the apparatus.
To solve the problems in the conventional arts, it is a primary object of the present invention to provide a screen unlocking method and an electronic apparatus thereof to solve the problem that the screen needs to be unlocked by touching a specific icon shown on the screen and dragging the icon toward a limited direction with a limited path.
To achieve the above object, a screen unlocking method according to the present invention applicable to an electronic apparatus having a touch-controlled screen is provided, the method comprises the following steps of: displaying a first frame over a second frame on the touch-controlled screen, wherein at least one movable icon is included in the first frame, and the icon shows a part of the second frame; touching the icon and dragging the icon with a random direction and a random dragging path, and the part of the second frame shown by the icon being enlarged or reduced according to the direction and the dragging path; determining if a dragging-condition of the icon is matched with any one of the unlocking-conditions; and displaying the whole second frame when the dragging-condition of the dragged icon is matched with one of the unlocking-conditions.
Wherein when the dragging-condition of the dragged icon is not matched with any one of the unlocking-conditions, then the part of the second frame shown by the icon is enlarged or reduced according to the direction and the dragging path, and then the icon goes back to an original position before being touched while the icon is not touched.
Wherein when the final position of the dragged icon is at one side of the touch-controlled screen, then the dragging-condition of the dragged icon is matched with one of the unlocking-conditions.
Wherein when the final position of the dragged icon is not at any side of the touch-controlled screen, and the velocity of the dragged icon is higher than a velocity threshold value and the distance that the icon being dragged is higher than a distance threshold value, then the dragging-condition of the dragged icon is matched with one of the unlocking-conditions.
Wherein the icon could be an animation.
To achieve the above object, an electronic apparatus according to the present comprises a touch-controlled and a control module. The touch-controlled screen displays a first frame over a second frame, and at least one movable icon which shows a part of the second frame is included in the first frame. The control module enlarges or reduces the part of the second frame shown by the icon after the icon being touched and dragged with a random direction and a random dragging path, and then determines whether a dragging-condition of the dragged icon is matched with any one of the unlocking-conditions. The control module further controls the touch-controlled screen displaying the whole second frame when the dragging-condition of the dragged icon is matched with one of the unlocking-conditions.
Wherein when the dragging-condition of the dragged icon is not matched with any one of the unlocking-conditions, then the part of the second frame shown by the icon is enlarged or reduced according to the direction and the dragging path by the control module, and then the control module controls the icon to go back to an original position before being touched while the icon is not touched.
Wherein when the final position of the dragged icon is at one side of the touch-controlled screen, then the dragging-condition of the icon is matched with one of the unlocking-conditions.
Wherein when the final position of the dragged icon is not at any side of the touch-controlled screen, and the velocity of the dragged icon is higher than a velocity threshold value and the distance that the icon being dragged is higher than a distance threshold value, then the dragging-condition of the icon is matched with one of the unlocking-conditions.
Wherein the icon could be an animation.
With the above arrangements, the electronic apparatus and the screen unlocking method thereof according to the present invention has one or more of the following advantages:
(1) It may be more convenient and interesting for the user using the touch-controlled screen when the screen is locked by a movable icon that shows some parts of the desktop.
(2) The convenience and flexibility could be raised when determining whether the screen is being unlocked according to the dragging speed, final position and dragging distance of a movable icon touched and dragged by a user.
