Method for dynamically unlocking screen and electronic device using the same

The present invention relates to a method for dynamically unlocking a screen, and more particularly to a method for dynamically unlocking a screen by using a touch method, and an electronic device to which the method is applied.

Nowadays, touch panels have been widely used in various portable electronic devices (notebooks, smart phones, PDAs, etc.) or display devices, and the instructions are input by finger touch to provide users with more intuitive and convenient functions. The operational experience. In general, in order to prevent such devices from being accidentally touched by non-users, unintended operations are most commonly used to lock the screen display. The principle is to execute a software program to generate a full screen protection interface to cover the original user interface to form a locking effect, thereby preventing false touch; until the user performs a specific unlocking operation, the protection interface can be cancelled to allow the user to Control the original user interface.

However, at present, the unlocking operation designed for the protection interface mostly sets a corresponding unlocking component at a fixed position of the protection interface, and defines an unlocked touch movement path, so the user must first click on the corresponding unlocking component, and then follow The specific path can be unlocked by sliding the touch operation. In this way, each time the user unlocks, the user needs to find the location of the unlocking component first, and does not offset the touch-moving path defined by the lock during the sliding process, so that the unlocking procedure is complicated and inconvenient.

Therefore, if you can match the animation display of the screen saver as an unlocking component and provide an unlocking path in an unlimited direction, it will give the user different operating experience and simplify the unlocking step.

The method includes the following steps: generating an animation randomly at any position of the protection interface, the animation includes a first range block and a second range block, and the first range block is in the second range block, wherein the animation is based on The time period is generated. The time period includes the appearance period, the duration period, and the disappearance period. The appearance period refers to the elapsed time when the animation appears from any position and gradually enlarges to the set size. The duration refers to the elapsed time during which the animation maintains the set size. The disappearance period refers to the elapsed time from the initial size of the animation to the complete disappearance; receiving a touch operation and determining whether the touch position is within the first range block; if the touch position is within the first range block Receiving, by the touch position as one of the moving starting points, sliding the touch operation to move the first range block according to the sliding touch operation; determining whether the first range block moves outside the second range block; When the first range block moves outside the second range block, the protection interface is removed to release the screen lock state.

In addition, the present invention also provides an electronic device applying the aforementioned method of dynamically unlocking a screen.

With the design of the present invention, in the screen locked state, the user can click on the animation randomly appearing on the touch screen, and perform an operation of sliding in an arbitrary direction and having a certain distance, thereby achieving the effect of unlocking the screen. It simplifies the steps of the unlocking operation and provides users with different operating feelings.

In order to enable the reviewing committee to better understand the technical contents of the present invention, the preferred embodiments are described below.

Please refer to FIG. 1 for a schematic diagram of an electronic device 100 of the present invention. In an embodiment of the present invention, the electronic device 100 is a smart phone, but depending on the type of application, the electronic device 100 can also be a tablet computer, a notebook computer, a personal digital assistant (PDA), and a global positioning system (GPS). , touch screen or other device that can be operated by touch mode, but not limited to this embodiment.

As shown in FIG. 1 , the electronic device 100 of the present invention includes a touch screen 110 and a processing module 120 , and the processing module 120 is electrically connected to the touch screen 110 . The touch screen 110 is a display screen capable of supporting touch input for receiving a touch operation of the user, and the user can perform single touch input, single point slip input or other touch input on the touch screen 110. The touch screen 110 is also used to display the corresponding display interface. In a normal state, the electronic device 100 displays an original user interface through the touch screen 110. For example, the electronic device 100 is in a central processing unit After loading the operating system, the system desktop can be displayed on the touch screen 110, or the corresponding program operation interface can be displayed according to the application executed by the user.

The processing module 120 is configured to perform a screen locking or unlocking operation and generate a corresponding display interface for display by the touch screen 110. In one embodiment of the present invention, the processing module 120 is a combination of a central processing unit and an application stored in a storage unit (eg, a hard disk, a memory, etc.), according to instructions issued by the central processing unit. The control application performs the aforementioned functions. However, the present invention is not limited thereto, and the processing module 120 may be formed by a single hardware (for example, a circuit, an electronic chip, etc.), a soft body, a firmware, or a combination of any two or more of the foregoing. When the electronic device 100 enters the screen lock state, the processing module 120 generates a protection interface to cover and lock the original user interface. The protection interface here may be an animation protection screen interface, but the invention is not limited thereto.

Please refer to FIG. 2, which is a flowchart of a method for dynamically unlocking a screen according to the present invention. It should be noted that although the electronic device 100 shown in FIG. 1 is taken as an example to illustrate the method for dynamically unlocking the screen of the present invention, the present invention is not limited to the electronic device 100, and any other electronic device having a similar structure. The device can also be adapted to the method of the invention. As shown in FIG. 2, the method for dynamically unlocking the screen of the present invention includes steps S201 to S205. The various steps of the method are described in detail below.

Step S201: An animation is generated randomly at any position of the protection interface, and the animation includes a first range block and a second range block, and the first range block is located in the second range block.

Please refer to Figure 3(a) to Figure 3(d) below. FIG. 3(a) is a schematic diagram showing an original use interface O in a normal state in an embodiment of the method for dynamically unlocking the screen of the present invention. FIG. 3(b) is a schematic diagram showing an embodiment of the method for dynamically unlocking the screen of the present invention in the screen locked state. FIG. 3(c) is a schematic diagram of an embodiment of the method for dynamically unlocking the screen of the present invention to generate an animation A at a random position C1 of the protection interface S. FIG. 3(d) is a schematic diagram of an embodiment of the method for dynamically unlocking the screen of the present invention to generate an animation A at another random position C2 of the protection interface S.

As shown in FIG. 3( a ), when the electronic device 100 is in a normal state, the touch screen 110 displays one of the currently loaded systems or one of the executed software interfaces (for example, a system desktop or a software program interface). Etc.) for the user to perform normal touch execution.

As shown in FIG. 3(b), when the electronic device 100 enters the screen lock state, the processing module 120 generates a protection interface S and displays it through the touch screen 110 to cover and lock the original user interface (not shown). ), preventing the touch screen 110 from being unintentionally touched. In this embodiment, the protection interface S adopts a non-transparent background image to shield the original user interface, and can still display information about the system or device through the protection interface S, such as date, time, power or connection status. However, it is not limited to this embodiment.

As shown in FIG. 3(c), the processing module 120 then randomly generates an animation A at any position on the protection interface S. The animation A includes a first range block A1 and a second range block A2; Block A1 is located in the second range block A2, and the first range block A1 and the second range block The edge of the range of A2 is kept at a certain distance. In this embodiment, the first range block A1 and the second range block A2 form a set of concentric circles, but the invention is not limited thereto, and the first range block A1 and the second range block A2 Other identical polygonal blocks may be used together, or both may be in different blocks. In addition, the first range block A1 and the second range block A2 can be separated by different colors to facilitate user identification.

In the present embodiment, the animation A is generated according to a time period, wherein the time period includes an appearance period, a duration period, and a disappearance period. The appearance period refers to the elapsed time when the animation A appears at any position of the protection interface S and gradually enlarges to a set size, and the duration refers to the elapsed time that the animation A maintains the set size display at the arbitrary position, and the disappearance period refers to The animation A is gradually reduced in size from the set position to the elapsed time. The length of time can be adjusted according to the setting or the demand during each period of the foregoing time period.

As shown in FIG. 3(c) and FIG. 3(d), in an embodiment of the present invention, the animation A appears at a random position C1 on the protection interface S for a period of time after a period of time elapses. Then disappears; then in the next time period, the animation A appears again at another random position C2, and disappears after a period of time, thus repeatedly generating the animation A. For example, suppose that the time period for generating the animation A is 3.5 seconds, and the occurrence period, duration, and disappearance period are 1 second, 1 second, and 1.5 second, that is, every 3.5 seconds, the different positions of the protection interface S are random. An animation A is generated to display an animation effect that appears, continues to disappear, but the invention is not limited thereto.

In order to save the power consumption of the electronic device 100, the processing module 120 can be correspondingly adjusted for the generation time of the animation A, for example, After waiting for a period of time after entering the screen lock state, the processing module 120 starts to periodically generate the animation A on the protection interface S; and after a certain number of time periods (ie, a certain number of animations A) If the processing module 120 has not received any operation related to the screen unlocking, the processing module 120 may pause the animation A to generate the protection interface S, and then wait for the touch screen 110 to receive the touch operation, and then re-execute the animation. The generation of A prevents the excess power loss of the electronic device 100. For example, if the set waiting time is 10 seconds and the time period is set to 8 times, it will take 10 seconds to start generating the animation A periodically after the electronic device enters the screen lock state, and appears in the animation A. After the disappearance has elapsed 8 times, the animation A is temporarily stopped, but the present invention is not limited thereto.

In addition, with different implementations, the animation A can also appear at any position of the protection interface S in an instant or disappear during the disappearance period (ie, the animation process of gradually zooming in or out is not displayed), that is, Animation A has a shorter period of appearance and disappearance, but maintains a relatively long duration between appearance and disappearance. Of course, the animation A can also use other animations to display the appearance, not limited to this.

Please refer to FIG. 3(e), which is a schematic diagram of another embodiment of the method for dynamically releasing the screen lock of the present invention to generate an animation A' in the protection interface S. As shown in FIG. 3(e), in the embodiment, the second range block A2' is designed such that the second range block A2' is a transparent or translucent block, so that the second range area is transmitted. Block A2' presents the corresponding original user interface O, providing the user with a different visual experience.

Step S202: Receive a touch operation and determine whether the touch position of the touch operation is located in the first range block. When the electronic device 100 is in the screen lock state, the user can perform a single touch input on the touch screen 110 through a finger or a stylus, etc., so that the touch screen 110 receives the point corresponding to the touch position. The touch operation is performed by signal conversion to notify the processing module 120. The processing module 120 can then determine whether the touch location of the touch operation is within the first range of the generated animation. If yes, the process proceeds to step S203; if not, the original state is maintained to wait for another touch operation.

In addition, in this embodiment, if the animation is currently in the expiration or disappearance period, it indicates that the animation is gradually being enlarged or reduced. At this time, if the touch screen 110 receives the touch operation and is judged by the processing module 120. When the touch position of the touch operation is located in the first range block of the animation, the processing module 120 will immediately enlarge or restore the animation (including the first range block and the second range block) to the set size of the duration. In order to facilitate the user to perform subsequent sliding touch operations.

Step S203: Receive a sliding touch operation by using the touch position as a moving starting point to move the first range block according to the sliding touch operation. If the touch position is located in the first range block, the user can perform the touch position as the movement start point and slide the touch input in one of the undefined directions while the user continuously touches the touch position. The touch screen 110 receives the sliding touch operation corresponding to the input, and signals the processing module 120 by signal conversion. The processing module 120 can correspond to the length of the sliding touch operation, corresponding to the first range of blocks on the mobile protection interface.

Step S204: It is determined whether the first range block moves outside the second range block.

During the sliding touch operation, the processing module 120 continuously detects the moving position of the first range block to determine whether the first range block moves outside the second range block. If yes, proceed to step S205; if not, continue to maintain the screen lock state.

Step S205: Remove the protection interface to leave the screen lock state. When the processing module 120 determines that the first range of the block has moved outside the second range of the block, the condition for releasing the screen lock is reached, and the processing module 120 is removed from the protection interface displayed by the touch screen 110. To leave the screen locked state.

Please refer to Figure 4(a) to Figure 4(b) together. FIG. 4(a) is a schematic diagram of an embodiment of a method for dynamically releasing a screen lock according to the present invention for receiving a sliding touch operation. 4(b) is a schematic diagram showing an embodiment of the method for dynamically releasing the screen lock of the present invention after the first range block A1 is moved.

As shown in FIG. 4( a ), when the user touches the touch position P0 through the touch operation, the touch position P0 can be moved in any direction (for example, each dotted arrow in the figure). The starting point performs the sliding touch input, and accordingly drives the first range block A1 to start moving; if the user has canceled the touch operation of the touch position P0 at this time, the protection interface S will continue to appear periodically. A, waiting for the user to click again.

As shown in FIG. 4(b), it is assumed that the first range block A1 has been moved from the original touch position P0 to a moving end point P1 according to the sliding touch operation (shown by the dotted arrow in the figure). The processing module determines that the moving end point P1 is located outside the second range block A2, that is, the screen lock has been reached. The condition is that the protection interface S is removed (for example, an animation in which the second range block A2 is gradually enlarged outward, so that the protection interface S disappears) to leave the screen lock state, and the touch screen 110 returns to FIG. In the state of (a), the original interface O is displayed again and the normal interface control function is restored.

By the method for dynamically unlocking the screen of the present invention, the unlocking component or the defined moving path of the fixed position on the interface is not required to be touched, and the movable animation can be released in any direction by touching a random animation of the touch screen. The screen lock of the device improves the convenience and fun of the unlocking operation, and further avoids the situation of unlocking due to accidental touch.
