Description

Electronic device and method for unlocking same and computer program product

The present invention relates to a method of operating an electronic device, and more particularly to a method of unlocking an electronic device and an electronic device using the same.

With the advancement of touch technology, touch screens have become more and more popular among electronic device manufacturers, and have gradually replaced traditional screens and keyboards as input and output interfaces for electronic devices. The use of a touch screen saves space in configuring the keyboard, which further reduces the size of the electronic device and provides a larger display area. In addition, the touch screen can not only accept the touch operation from the user, but also directly present the result of the operation. For the user, using the touch screen to operate the electronic device can obtain a more intuitive and convenient feeling.

However, the electronic device configured with the touch screen must have a screen locking mechanism to prevent the user from inadvertently touching the touch screen to initiate unnecessary functions. In many common electronic device unlocking mechanisms, most of them are defined by the start and end points of the unlocking action, and the user is required to make a gesture corresponding to the preset trajectory on the touch screen to smoothly unlock. However, it is not difficult to imagine that in some usage scenarios, it is not easy for a user to make a start point, an end point, and a trajectory that conform to a system-defined unlock gesture, and thus may be inconvenient when an electronic device is urgently needed.

In view of the above, the present invention provides a method and an electronic device for unlocking to provide a more flexible and functionally unlocked manner.

The present invention provides a method for unlocking an electronic device having a touch screen and being locked, the method comprising detecting a touch applied to any position on the touch screen. When the touch moves, the physical scalar quantity generated by the touch movement is used as the power of the preset autonomous motion, and the touch screen displays the process that the object is driven by the power and presets the autonomous motion according to the rules, wherein the preset autonomy is preset. The rules of action are predefined in the electronic device. When the object performs the preset autonomous action according to the rule and reaches the completion state, the electronic device is unlocked.

In an embodiment of the invention, the object is displayed at the position where the touch is first detected or displayed at the preset position before starting the preset autonomous motion.

In an embodiment of the present invention, wherein the physical scalar quantity is a path length that is passed when the touch persists, the method for unlocking further includes an increase in the path length in the process of the object performing the preset autonomous action according to the rule. Improve the progress to the completion status.

In an embodiment of the invention, the method of unlocking further comprises determining whether the preset autonomous action has a corresponding completion state. If not, the speed of the preset autonomous action is changed according to the change of the power when the touch is present. When the touch disappears, the power is gradually reduced and the preset autonomous motion is slowed down, and the electronic device is unlocked until the power consumption is completed.

In an embodiment of the invention, wherein the physical scalar amount is the rate at which the touch moves.

From another point of view, the present invention provides an electronic device including a touch screen, a storage unit, and a processing unit. The touch screen is used to detect touch. The storage unit records rules for pre-set autonomous actions. The processing unit is coupled to the touch screen and the storage unit. When the touch screen is locked and the touch is detected, the processing unit uses the physical scalar quantity generated by the touch movement as the power of the preset autonomous motion, and displays the object on the touch screen and is driven by the power. Rules perform the process of prescribing autonomous actions. When the object performs the preset autonomous action according to the rule and reaches the completion state, the processing unit unlocks the electronic device.

In an embodiment of the invention, the object is displayed at the position where the touch is first detected or displayed at the preset position before starting the preset autonomous motion.

In an embodiment of the present invention, wherein the physical scalar quantity is a path length that is passed when the touch persists, the processing unit increases the progress of reaching the completion state as the path length increases during the preset autonomous action of the object rule. .

In an embodiment of the invention, the processing unit determines whether the preset autonomous action has a corresponding completion status. If not, the processing unit changes the speed of the preset autonomous motion according to the change of the power when the touch exists, and gradually reduces the power when the touch disappears and correspondingly slows down the preset autonomous motion until the power consumption is completed to unlock the electronic device.

In an embodiment of the invention, wherein the physical scalar amount is the rate at which the touch moves.

From another point of view, the present invention provides a computer program product that can perform the above-described unlocking method after the electronic device is loaded into the computer program product and executed.

Based on the above, the present invention detects the user's action of touching the touch screen and moving the finger (or inputting the tool) to cause the unlocking process to proceed when the electronic device is locked. Since the unlocking condition is not limited by the starting point of the touch and the shape of the track, the elasticity of the unlocking operation can be increased.

The above described features and advantages of the present invention will be more apparent from the following description.

1 is a block diagram of an electronic device in accordance with an embodiment of the present invention. Referring to FIG. 1 , the electronic device 100 includes a touch screen 110 , a storage unit 120 , and a processing unit 130 . In this embodiment, the electronic device 100 may be a mobile phone, a personal digital assistant, a smart phone, a tablet computer, an e-book, or a game machine. The type of the electronic device 100 is not limited herein.

The touch screen 110 is an input and output interface of the electronic device 100, and can display various operation screens of the electronic device 100 and can receive a touch operation of the user. For example, the touch screen 110 can be a resistive touch screen, a capacitive touch screen, an optical touch screen, or an electromagnetic touch screen.

The storage unit 120 can be built in the electronic device 100 or externally connected to the electronic device 100 through a specific interface. The storage unit 120 is, for example, a memory, a hard disk, a compact disc, a memory card, a flash drive, or the like.

The processing unit 130 is coupled to the touch screen 110 and the storage unit 120. When the electronic device 100 is locked, the processing unit 130 performs a method of unlocking according to an embodiment of the present invention to switch the locked electronic device 100 to an unlocked state. In an embodiment, processing unit 130 may be a central processing unit or other programmable microprocessor.

It is to be noted that, in the embodiment, the electronic device 100 is locked, that is, the input interface such as the touch screen 110 or the keyboard is locked, and the locked electronic device 100 cannot input according to the user's input to the touch screen 110 or the keyboard. Most of the functions are performed by the operation of the interface. In another embodiment, the electronic device being locked means that the electronic device presents a specific user interface and can only perform functions triggered by the specific user interface.

Hereinafter, each step of the method of unlocking according to the present embodiment will be described with reference to FIG. 2 with reference to FIG.

First, as shown in step S210, the touch screen 110 detects a touch applied to any position on the touch screen 110. For example, after the electronic device 100 is locked, the touch sensing component of the touch screen 110 can still receive a touch from any position applied by the user to the surface of the touch screen 110 and generate a corresponding signal. The signal after the controller of the control screen 110 processes (eg, converts the signal format and embeds information related to the touch location) will be transmitted to the processing unit 130. As long as the touch persists, the signal corresponding to the touch is continuously transmitted to the processing unit 130. Therefore, the processing unit 130 can determine whether the touch is still present and whether the touched position is changed by the signal from the touch screen 110.

Then, as shown in step S220, when the touch moves, the processing unit 130 starts the power of the preset autonomous motion by using the physical scalar quantity generated by the touch movement as an object. In this embodiment, the touch must be moved to drive the object to start the preset autonomous action. Therefore, if the user only continuously touches the touch screen 110 with a finger (or other input tool) but does not move, the object is lack of power. Instead of starting a preset autonomous action. It must be stated that the physical scalar quantity regarded as power refers to the physical quantity of non-directionality. For example, the physical scalar quantity may be the path length of the touch movement, which is the length of the trajectory that the user passes when the touch screen 110 is moved by the finger (or other input tool), and only the size and the limit are not limited. The direction of movement. The physical scalar quantity can also be the rate at which the touch moves, that is, the length of the path that the touch takes in unit time. Alternatively, the physical scalar quantity may also be the force of the touch when moving, regardless of the direction of the force applied. That is to say, any physical scalar quantity having only size and irrelevant direction can be taken as the power of the preset autonomous action by the processing unit 130. In the present embodiment, the rules for autonomously autonomous actions (eg, the manner in which the actions are performed, the flow, etc.) have been previously defined and recorded in the storage unit 120 of the electronic device 100.

Next, as shown in step S230, the processing unit 130 displays on the touch screen 110 a process in which the object is driven by the power and performs a preset autonomous action according to the rules recorded by the storage unit 120. During the touch, the movement of the touch on the touch screen 110 (for example, the user sliding a finger or other input tool on the touch screen 110) can continuously provide the object with the power to perform a preset autonomous action, such as increase or decrease of the power. The speed of the preset autonomous motion of the object is affected. For example, when the power is increased, the processing unit 130 accelerates the object to perform the preset autonomous motion, and the power reduction does not change the speed of the preset autonomous motion. It should be noted, however, that the preset autonomous motion of the object is performed according to the rules recorded by the storage unit 120, and the change in the position of the touch does not change the direction in which the motion is performed. In other words, in the process of performing the preset autonomous motion, the display position of the object on the touch screen 110 is independent of the current touch position, so the user does not need to touch the object to move it.

In this embodiment, the object may be a scrambled puzzle, a scrambled magic square, or a ball. The corresponding preset autonomous actions are, for example, performing a puzzle, restoring a magic square, and moving the ball toward a preset destination. Further, the rules for performing the puzzle include the moving order and placement position of the pieces of the puzzle, and when the puzzle has been spelled back to the complete pattern, the action of the puzzle is said to have reached the completion state. The rules for restoring the magic square include the rotation order and direction of the blocks, and when the scrambled magic square has been restored to only one color per side, the action is said to have reached the completion state. The rule that moves the ball toward the preset destination includes a scrolling route, and when the ball reaches the preset destination, the action is said to have reached the completion state. However, the above objects, preset autonomous actions, rules, and completion states are merely examples for the sake of explanation, and the present invention is not limited thereto. In other words, the preset autonomous action can be any action having a completed state, and the subject performing the action can be used as the object of the embodiment.

In step S240, the processing unit 130 determines whether the object performs the preset autonomous action according to the rule to reach the completion state. If not, the process returns to step S240 to repeat the determination until the object reaches the completion state by the preset autonomous action according to the rule. As shown in step S250, the processing unit 130 unlocks the electronic device 100. After the electronic device 100 is unlocked, the user can use all the functions of the electronic device 100.

As shown in FIG. 2, after the electronic device 100 is locked, when the touch screen 110 first detects a touch at any position on the display plane, an object is ready to start a preset autonomous motion, and the object is on the touch screen 110. The display position on the top is, for example, the position of the first touch or the system preset position. Once the touch has moved, the processing unit 130 causes the object to officially begin to perform a predetermined autonomous action in accordance with predefined rules. During this period, the physical scalar quantity of the continuous touch movement can continue to be the power of the preset autonomous motion, and the speed of the object to perform the preset autonomous motion can be changed. As long as the object reaches the completion state according to a predefined rule, the electronic device 100 will be unlocked regardless of whether the touch still exists. In other words, the embodiment shown in FIG. 2 provides an operation method that does not limit the start and end positions of the touch, and does not limit the touch trajectory to unlock the electronic device 100, thereby improving the convenience of unlocking.

3A-3C are schematic diagrams of preset autonomous actions of an object according to an embodiment of the invention. In this embodiment, the physical scalar quantity that the processing unit 130 considers as power to start the unlocking program is the path length that is passed when the touch persists, and the object is a ball, and the preset autonomous motion is to make the ball toward the preset destination. Move, the completion status is when the ball reaches the preset destination.

As shown in FIG. 3A, after the electronic device 100 is locked, when the touch screen 110 first detects a touch by the user with the finger 31 (which can occur anywhere in the touch screen 110), the processing unit 130 according to the touch The initial position S of the touch is used to display the ball 33, and an icon for indicating the preset destination 35 is displayed, for example, in the lower right corner of the touch screen 110.

Once the user begins to slide their finger 31 on the touch screen 110, the ball 33 will have the power to move to the preset destination 35 and begin to move. As shown in FIG. 3B, the processing unit 130 causes the ball 33 to gradually move toward the preset destination 35 according to a predefined rule, and the moving process is displayed on the touch screen 110. For example, the predefined rule includes a moving trajectory R (indicated by a broken line in FIG. 3B), and the ball 33 will follow the preset movement trajectory R for a preset purpose regardless of the trajectory P of the finger 31 sliding. Ground 35 moves. That is to say, the direction in which the ball 33 moves is independent of the direction in which the finger 31 slides. In the present embodiment, it is not necessary to control the ball 33 to reach the preset destination 35 by the sliding of the finger 31, and the position of the finger 31 does not affect the movement of the ball 33. Track. However, in the process in which the ball 33 moves toward the preset destination 35 in accordance with the preset movement trajectory R, the path length of the sliding track P with the finger 31 increases, and the progress of reaching the completion state (the ball 33 reaches the preset destination 35) is also progressed. Will increase accordingly. For example, the progress to the completion state may be proportional to the increase in the path length, and the path state will immediately reach the completion state when the path length is increased to a preset value.

As shown in FIG. 3C, as long as the ball 33 reaches the preset destination 35, the electronic device 100 will be unlocked regardless of whether the finger 31 still touches the touch screen 110 or is still sliding.

As shown in FIG. 3B and FIG. 3C, the screen content displayed on the touch screen 110 can be used to indicate the extent to which the user is currently unlocked, but the screen content is not used to indicate how the user performs the unlocking operation.

In another embodiment of the present invention, the electronic device 100 can provide a more diverse unlocking method. 4 is a flow chart of a method of unlocking according to another embodiment of the present invention. Please refer to FIG. 1 and FIG. 4 at the same time. However, since steps S410 to S430 of FIG. 4 are the same as or similar to steps S210 to S230 of FIG. 2, details are not described herein again.

In this embodiment, as shown in step S440, the processing unit 130 determines whether the preset autonomous action has a corresponding completion state. For example, the storage unit 120 records the rules of the preset autonomous action, and the processing unit 130 can determine whether the preset autonomous action has a completed state. Further, the preset autonomous action that does not have a completed state is, for example, an action that can be continued or circulated without stopping in the presence of power, such as rolling a prayer cylinder of a Tibetan lama temple, inciting a scorpion, and the like. The corresponding rules are, for example, the direction in which the blessing cylinder rotates, the amplitude of the scorpion swaying, and the like.

If the preset autonomous action does not have a completed state, then in step S460, the processing unit 130 determines whether the touch exists. That is, it is determined whether the user removes the finger or the input tool from the touch screen 110.

If the touch still exists, in step S465, the processing unit 130 changes the speed of the preset autonomous action according to the change of the power. For example, when the power is increased, the preset autonomous motion is accelerated, and when the power is reduced, the preset autonomous motion is gradually slowed down. Next, returning to step S460, it is again determined whether the touch still exists.

If the touch has disappeared, there should be residual power at this time, so as shown in step S470, the processing unit 130 gradually reduces the power and correspondingly slows down the preset autonomous action. The move is to simulate a dynamic object in nature that slows its action due to frictional power consumption.

Next, in step S480, the processing unit 130 determines whether the power is consumed. If no, the process returns to step S470. In this embodiment, steps S470 to S480 are repeated until the processing unit 130 determines that the power has been consumed. Then, as shown in step S490, the processing unit 130 unlocks the electronic device 100.

Please return to step S440, if the preset autonomous action has a completed state, and then repeatedly determine in step S450 whether the object performs the preset autonomous action according to the rule and reaches the completion state until the completion state is reached, as shown in step S490, the processing unit 130 unlocks the electronic device 100. Since step S450 and step S490 are similar to step S240 and step S250 of FIG. 2, they are not described herein again.

In the present embodiment, for a preset autonomous motion that does not have a completed state, the physical autonomous amount generated by the continuous touch is used as a driving force to drive the object to perform a preset autonomous motion. Once the user stops touching the touch screen 110, the processing unit 130 causes the object to continue to operate until the power consumption is completed. The locking of the electronic device 100 is released when the power consumption is completed.

5A-5C are schematic diagrams showing preset autonomous actions of an object according to another embodiment of the present invention. In this embodiment, the physical scalar quantity that the processing unit 130 considers as the power to start the unlocking program is the speed when the touch moves, the object is the prayer cylinder of the Tibetan Lama Temple, and the preset autonomous motion is the rolling prayer cylinder, and The rule is to scroll the blessing cylinder counterclockwise.

As shown in FIG. 5A, in a state where the electronic device 100 is locked, when the user touches the touch screen 110 with the finger 51, the processing unit 130 displays the prayer cylinder 53 at a preset position of the touch screen 110. In another embodiment, the processing unit 130 facilitates the display of the blessing cylinder 53 by the touch screen 110 before detecting the touch of the finger 51.

Once the finger 51 begins to slide on the touch screen 110, as shown in FIG. 5B, the processing unit 130 determines the power at the rate of the touch movement and causes the prayer cylinder 53 to start scrolling in the counterclockwise direction. It should be noted that the initial position S of the touch shown in FIGS. 5A and 5B is only for illustrative examples. The user can touch any position on the touch screen 110 and move the finger 51 to drive the prayer cylinder 53. Start scrolling. In the present embodiment, the prayer cylinder 53 does not change its display position with the trajectory P of the finger 51 sliding, but with the change of the path length of the sliding trajectory P per unit time (that is, the change of the rate), the blessing circle The speed at which the barrel 53 rolls can also change.

If the user removes the finger 51 from the touch screen 110, as shown in FIG. 5C, before the power consumption is completed, the prayer cylinder 53 will still roll in a counterclockwise direction, but the rotation will be slower as the power is reduced until the power is turned. When the complete consumption is completed, the prayer cylinder 53 stops scrolling and unlocks the electronic device 100.

In an embodiment of the invention, the processing unit 130 may include a power determining unit (not shown) to determine the magnitude of the power according to the physical scalar quantity generated by the touch movement on the touch screen 110. For example, the power decision unit can determine the power by looking up the table, or calculate the power by using the logic gate responsible for the operation. The processing unit 130 may further include an object actuation unit (not shown) and a picture management unit (not shown), wherein the object actuation unit calculates a preset autonomous motion according to the rules according to the dynamics, and the preset is performed by the picture management unit. The process of autonomous motion is displayed on the touch screen 110. The processing unit 130 further includes an unlocking unit (not shown) to release the locking of the electronic device 100 when the object reaches the completed state.

The present invention further provides a computer program product for performing the above method of unlocking. The computer program product basically consists of a plurality of program instructions (such as setting program instructions or deploying program instructions, etc.), and after loading the program instructions into the electronic device and executing them, each of the methods for unlocking the above can be completed. step.

In summary, the electronic device and the method for unlocking the same according to the present invention provide power to start an unlocking program according to sliding at any position on the touch screen, and display a screen indicating the progress of the unlocking program on the touch. The screen, however, the position of the object on the screen is not affected by the current touch position. When the object performs the preset autonomous motion and reaches the completion state or the power consumption is completed, the electronic device is unlocked. Accordingly, the user can unlock the electronic device in a more convenient and flexible manner without following a predetermined touch gesture.
