Description

Screen unlocking method

The present invention relates to a method of operating a user interface, and more particularly to a method of unlocking a screen.

In today's era of information explosion, human life is inseparable from electronic communication. People often use portable electronic devices to transmit messages to each other, especially mobile communication devices that can be carried around, such as mobile phones or with wireless communication. Functional mobile devices, etc. However, for a portable, mobile device that requires a light, thin, short, and small form factor, its own size is limited. Therefore, the touch screen system uses the keyboard to be integrated into the screen as a portable electronic device. The input interface of the device can save the cost and the occupied area of the traditional keyboard.

However, the touch screen is very sensitive to external touches, and the user may inadvertently touch the screen button displayed on the touch screen to accidentally perform a specific function, such as a call function. Therefore, the mobile device has a screen lock mode to prevent the touch screen from being accidentally touched by the user.

In the screen lock mode, the user must complete a specific unlocking operation before the input interface can be used normally. Then, the user operates the touch screen to open and execute the required application.

The invention provides a screen unlocking method, which is convenient for a user to simultaneously execute a corresponding application when unlocking a screen.

The invention provides a screen unlocking method suitable for an electronic device with a touch screen. In the method, in the screen lock mode of the electronic device, the touch screen is used to detect the touch operation of the user, and it is determined whether the touch start position of the touch operation is within the sensing range of the unlock icon. If the touch start position is within the sensing range of the unlock icon, a prompt box corresponding to the unlock icon is displayed on the touch screen. When the unlocking icon is dragged by the touch start position, and the displacement amount of the unlocking icon being dragged in a specific axial direction is greater than a preset value, the prompt frame is correspondingly moved along a specific axial direction. When the touch end position of the touch operation falls within the prompt box, the screen lock mode is released and the application corresponding to the unlock icon is turned on.

In an embodiment of the present invention, when the displacement amount of the unlocking icon being dragged in a specific axial direction is not greater than a preset value, the prompt box is not moved.

In an embodiment of the present invention, when the displacement amount of the specific axial direction being dragged is greater than a preset value, the unlocking icon is in the step of correspondingly moving the prompt frame along a specific axial direction, and when the unlocking icon is along a specific axis When the first direction of the direction is dragged, the cue frame is moved along the second direction of the specific axis. When the unlocking icon is dragged from the first direction of the specific axial direction to the second direction, the cue frame is moved from the second direction of the specific axial direction to the first direction. Here, the first direction and the second direction are corresponding directions.

In an embodiment of the present invention, the display area of the cue frame becomes larger as moving in the second direction toward the specific axis, and becomes smaller as moving in the first direction of the specific axis.

In an embodiment of the present invention, in the step of correspondingly moving the prompt frame along a specific axial direction, the prompting frame may be correspondingly moved along a specific axial direction at a sliding speed according to the drag speed of the touch operation. Here, the drag speed and the slide speed are in a preset ratio.

In an embodiment of the invention, the touch operation stops moving the prompt box when being dragged into the prompt box. In addition, when the touch operation is dragged into the prompt box, the color of the prompt box can also be changed.

In an embodiment of the invention, when the touch start position is detected within the sensing range of the unlock icon, the other unlock icons on the touch screen are hidden. In addition, when it is detected that the touch start position is within the sensing range of the unlock icon, a prompt box corresponding to the unlock icon is displayed on one edge of the touch screen.

In an embodiment of the present invention, when the touch operation is dragged into the prompt box, an explanation screen of the application corresponding to the unlock icon is displayed in the prompt box.

Based on the above, the present invention enables the user to unlock the screen and execute an application through the touch operation when using the electronic device with the touch screen, thereby saving the desire to operate the screen after unlocking the screen. The steps and time of opening the application enhances the user's convenience in using a mobile device with a touch screen.

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

Generally, in the screen lock mode, the user must complete a specific unlock operation before the input interface can be used normally. The invention provides a screen unlocking method, in which the screen lock mode can be released when the unlock icon overlaps with the prompt frame, so as to avoid the user unlocking the screen due to a false touch. In order to clarify the content of the present invention, the following specific examples are given as examples in which the present invention can be implemented.

1 is a flow chart of a method for unlocking a screen according to an embodiment of the invention. The embodiment is applicable to an electronic device having a touch screen, such as a mobile phone, a personal digital assistant, a personal digital assistant mobile phone, a smart phone, a tablet computer, a notebook computer, and the like. Moreover, for example, a computer software can be written in a programming language, and the computer software is installed in a storage unit of the electronic device, so that the computer software is executed by the processor to implement the steps of the bottom screen unlocking method.

In this embodiment, when the electronic device has entered the screen lock mode, the processor determines whether to cancel the screen lock mode or release the screen lock mode and execute the corresponding application according to the touch operation of the user on the touch screen. The electronic device enters the screen lock mode automatically, for example, when the user does not detect the operation for a certain period of time, or enters the screen lock mode when receiving the indication signal of the screen lock function, and does not limit the number thereof. range.

Referring to FIG. 1 , in step S105 , the touch screen is used to detect the touch operation of the user in the screen lock mode of the electronic device. The user performs a touch operation on the touch screen, for example, a finger (or a stylus) touches the touch screen to start the drag operation until the finger (or stylus) leaves the touch screen. The position where the finger (or stylus) touches the touch screen is the touch start position, and the position where the finger (or stylus) leaves the touch screen is the touch end position.

Next, in step S110, it is further determined whether the touch start position of the touch operation is within the sensing range of the unlock icon. For example, in the screen lock mode, the touch screen can display another lock screen instead of the display screen in the normal state of the screen lock mode. At least one unlock icon is included in the lock screen. This unlock icon is, for example, an illustration of the application. And, the unlock icon has a sensing range. The size of this sensing range is, for example, the same as the size of the unlocking icon, or larger than the size of the unlocking icon. In addition, in other embodiments, the display screen in the normal state may be directly used as the lock screen, and the scope thereof is not limited herein.

If the touch start position of the touch operation is within the sensing range of the unlock icon, as shown in step S115, the prompt box corresponding to the unlock icon is displayed at the preset position of the touch screen. For example, when the touch screen detects that a touch signal is generated within the sensing range of the unlock icon, the prompt box corresponding to the touched unlock icon is displayed at the preset position of the touch screen. If the touch start position of the touch operation is not within the sensing range of the unlock icon, the prompt box will not be displayed, and the electronic device will remain in the screen lock mode, and the touch screen continuously detects the user's Touch operation.

For example, when it is detected that the touch start position is within the sensing range of the unlock icon, the prompt box corresponding to the unlock icon may be displayed on the edge of the touch screen, so that the unlock icon and the position of the prompt frame are displayed. For the corresponding. For example, the unlocking icon and the prompt box may be opposite to each other or up and down. The initial preset position of the prompt box is set at the edge of the touch screen, so that the subsequent prompt frame can move at a larger distance when moving. However, this does not limit the initial preset position of the prompt box.

It is worth mentioning that this prompt box is related to the unlock icon. Assuming the unlock icon is an icon for the SMS app, information about the SMS app will appear in the prompt box. For example, when the unlock icon of the SMS application is touched and the corresponding prompt box is displayed on the touch screen, the prompt text such as "Open SMS Inbox" is displayed in the prompt box. In addition, the prompt text in the prompt box can be determined according to the number of messages received by the application. For example, when there is a new unread message, the prompt box displays a message such as "read new message"; when there is no new message that is not read, the message box "turn on SMS inbox" is displayed. This is for illustrative purposes only and is not intended to be limiting.

In addition, when the unlocking screen includes two or more unlocking icons, when the touch starting position is detected to be within the sensing range of one of the unlocking icons, the other unlocking maps on the touch screen may be displayed. Show hidden or dim the brightness. Alternatively, the unlocked icon to be clicked is presented in a visual effect floating on the unlocking screen such that the unlocking icon presents a visual effect that is absorbed by the user's finger.

Next, in step S120, when the displacement amount of the unlocking diagram being dragged in a specific axial direction is greater than a preset value, the prompt frame is correspondingly moved along a specific axial direction. Specifically, when it is detected that the touch start position is within the sensing range of the unlock icon, it is determined whether the displacement amount of the unlock icon in a specific axial direction is greater than a preset value. When the unlocking icon is not dragged by the predetermined amount in the specific axial direction, the above-mentioned prompt box is not moved. When the unlocking icon is dragged in a specific axial direction by more than the preset value, the prompt box is relatively moved.

More specifically, when the unlocking icon is dragged along the first direction of the particular axis, the cue is moved along the second direction of the particular axis. When the unlocking icon is dragged from the first direction of the specific axis to the second direction, the cue frame is moved to the first direction by the second direction of the specific axis. Here, the first direction and the second direction are corresponding directions. In addition, the display area of the cue frame becomes larger as it moves in the first direction toward the specific axis, and becomes smaller as it moves in the second direction toward the specific axis.

Assume that this particular axis is the X axis and assumes a preset value of zero. When the processor determines that the displacement amount of the unlocking diagram on the X-axis is greater than 0, the prompt frame is correspondingly moved along the X-axis. For example, assume that the first direction is the positive direction of the X-axis and the second direction is the negative direction of the X-axis. When the user drags the unlock icon from the touch start position to the right (the positive direction of the X-axis), the prompt frame moves relatively to the left (negative direction of the X-axis).

In addition, the prompt frame may be correspondingly moved along a specific axial direction at a sliding speed according to the drag speed of the touch operation. Here, the drag speed and the slide speed are in a preset ratio. For example, the sliding speed of the prompt box is set to be smaller than the drag speed of the unlocking icon, for example, the drag speed is twice the sliding speed. According to this, when the unlocking icon is dragged, the user can know whether the currently performed action is correct through the movement of the prompt box. That is, the reminder frame can be continuously moved during the dragging of the unlocking icon to induce the user to continue dragging the unlocking icon.

Next, in step S125, when the touch end position of the touch operation falls within the prompt box, the screen lock mode is released and the application corresponding to the unlock icon is turned on. That is to say, when the user releases his finger (or stylus) and the prompt box is released, the screen lock mode is released, and the application corresponding to the unlock icon is simultaneously turned on. If the touch end position does not fall within the prompt box, the screen lock mode will not be released and the electronic device will remain in the screen lock mode.

In addition, when the touch operation is dragged into the prompt box, the moving prompt box can be stopped, and the color of the prompt box can also be changed. In addition, an explanation screen of the application corresponding to the unlock icon can be displayed in the prompt box. For example, an application's user interface can be displayed in a prompt box. For example, if the application corresponding to the unlock icon is a phone application, when the touch operation is dragged into the prompt box, a call interface may be displayed in the prompt box to inform the user that after the touch operation is finished, What is the user interface that is turned on.

According to this, when the user drags the unlock icon to the direction of the prompt box, the prompt box will perform the corresponding movement with the unlock icon, and when the unlock icon has been dragged into the prompt box, the prompt box will reflect In a state that can be safely unlocked, after the user releases the unlock icon, the electronic device automatically releases the screen lock mode and performs the corresponding function.

In order to more clearly illustrate the process of unlocking the screen, the description is illustrated below. 2A-2D are screen diagrams showing a screen unlocking process according to an embodiment of the invention. In this embodiment, the capacitive touch screen is taken as an example. However, in other embodiments, the touch screen can also be a resistive type, and the type of the touch screen is not limited herein. Referring to FIG. 2A to FIG. 2D, the lock screen 200 is a screen displayed by the touch screen in the screen lock mode. For example, after the electronic device enters the screen lock mode, when the power switch of the touch screen is enabled, the lock screen 200 is displayed on the touch screen.

In FIG. 2A, it is assumed that the lock screen 200 includes two unlock icons 210 and 220. The unlock icon 210 is an illustration of a phone application, and the unlock icon 220 is an illustration of a newsletter application. Here, the unlock icon displayed in the lock screen 200 may be preset by the system, or the user may set which applications to include (including a phone application, a newsletter application, a social networking application, etc.) Set to unlock the icon. In addition, in the present embodiment, the sensing range of the unlocking icon 210 and the unlocking icon 220 is the range within the circle.

Next, referring to FIG. 2B, when the user's finger touches the unlock icon 210, a prompt box 230 is displayed on the unlock screen 200. Here, the preset position of the prompt box 230 is at the right edge of the touch screen. However, in other embodiments, the preset position of the prompt box 230 may be determined according to the location of the unlock icon 210.

Then, the user can drag the unlock icon 210 on the touch screen. In FIG. 2C , when the user drags the unlock icon 210 to the first direction 241 , the prompt frame 230 moves in the second direction 243 as the unlock icon 210 is dragged. That is, the unlock icon 210 moves corresponding to the prompt frame 230. Further, when the prompt frame 230 moves in the second direction 243, its display area becomes larger as it moves. Here, the dashed box represents the starting position of the unlocking icon 210, and the user drags the unlocking icon 210 by the dashed box.

When the user continues to drag the unlock icon 210 to the right, the prompt box 230 will continue to move to the left until the touch position of the user's finger overlaps with the prompt box 230, as shown in FIG. 2D. At this time, when the user releases the finger, the screen lock mode can be released and the user interface corresponding to the phone application can be opened. For example, when there is a missed call, the user interface for the call is opened; and when there is no missed call, the contact list can be opened for the user to select the object to be called. Although the description is taken as an example of "the user unlocks the screen when the finger is released", the present invention is not limited thereto. In another embodiment, when the user's finger touches the position and the prompt box 230 When overlapping, you can directly release the screen lock mode.

In addition, when the unlock icon 210 is dragged from the positive direction of the X-axis to the negative direction, the prompt frame 230 is moved from the negative direction of the X-axis to the positive direction, and the display area of the prompt frame 230 becomes smaller (as shown in the figure). 2C to Figure 2B). However, when the unlock icon 210 has not been displaced in the positive direction of the X-axis, if the unlock icon 210 is dragged in the negative direction, the prompt frame 230 does not move in the positive direction.

It is worth mentioning that the dragging of the touch operation does not necessarily have to be dragged by a straight line, and may also be an irregular drag. As long as the displacement of the touch operation on the X axis is greater than 0, the prompt box 230 will follow the touch operation. The amount of displacement in the X-axis moves relative to each other.

For example, FIG. 3 is a schematic diagram of another screen unlocking process according to an embodiment of the invention. In this embodiment, FIG. 2A and FIG. 2B are taken as an example to further illustrate that the dragging of the touch operation may also be an irregular drag.

Referring to FIGS. 2A and 2B , when the user touches the unlock icon 210 , the prompt frame 230 is displayed on the unlock screen 200 . Next, referring to FIG. 3, the user drags the unlock icon 210 along the drag track 245 on the touch screen. That is, the user first drags the unlock icon 210 to the upper right, and then the unlock icon 210 to the right to the prompt box 230 210. Since the unlocking icon 210 has generated a displacement amount in the positive direction of the X-axis, the prompt frame 230 moves in the negative direction of the X-axis in accordance with the amount of displacement of the unlocking icon 210 in the positive direction of the X-axis. Accordingly, the prompt frame 230 can be moved as long as the displacement amount of the specific axial direction is greater than the preset value.

In addition, the prompt information of each of the unlock icons 210 and 220 may be displayed on the unlock screen 200 for the user to understand the application programs corresponding to the unlock icons 210 and 220. An embodiment will be described below.

4A-4D are screen diagrams showing still another screen unlocking process according to an embodiment of the invention. Referring to FIG. 4A to FIG. 4D , in the embodiment, the unlocking screen 400 includes an unlocking icon 410 and an unlocking icon 420 , and the unlocking icons 410 and 420 respectively have a prompt message for explaining the function of unlocking the icon. . Here, the unlock icon 410 is an icon of the phone application, and when the electronic device has a missed call, a prompt message such as “1 missed call” is displayed on the unlock screen 400. The unlock icon 420 is an icon of the newsletter application. When the electronic device has an unread newsletter, a prompt message such as "1 new message" is displayed on the unlock screen 400. The unlocking icon 410 and the unlocking icon 420 respectively have a larger sensing range 411 and a sensing range 421. Accordingly, when the user's finger touches the sensing range 411 or the sensing range 421, the unlocking icon 410 or the unlocking icon 420 can be dragged to facilitate the operation. Here, the sensing range 411 and the sensing range 421 are drawn in a dotted line frame to indicate that the sensing range 411 and the sensing range 421 are not displayed in the unlocking screen 400 when the touch is not performed.

In addition, in other embodiments, a number may be indicated on the unlock icon as a reminder message according to the number of missed calls, unread messages, or application prompt messages.

Next, referring to FIG. 4B, when the user touches the sensing range 411 of the unlock icon 410, the entire sensing range 411 is displayed in the unlocking screen 400, and the unlocking icon 420 is hidden and unlocked. A prompt box 430 is displayed on the screen 400.

Then, when the user drags the unlock icon 410 to the right, the prompt box 430 moves to the left as shown in FIG. 4C. Then, when the user continues to drag the unlock icon 410 to the right so that the user's finger and the prompt frame 430 overlap each other, the user can release the screen to release the screen lock mode and open the user of the phone application. interface.

In summary, in the above embodiment, the user can use the touch operation to unlock the screen and execute an application at the same time when using the electronic device with the touch screen. Moreover, the prompting box is used to prompt the user for the function of the unlocking icon that is dragged. In addition, the user can continue to drag the unlocking icon to unlock by the corresponding movement of the unlocking icon and the prompting frame. According to this, not only the steps and time of the application to be opened after the screen is unlocked can be saved, the convenience of the user using the mobile device with the touch screen is improved, and the user can be induced to unlock correctly. .
