Method for unlocking electronic system with touch screen, setting method for customized gesture, and control device with customized unlocking function

The present invention relates to an electronic system for a touch screen, and more particularly to an input method for locking and unlocking an electronic system of a touch screen.

Touch screens have grown considerably in recent years, and more and more electronic systems have adopted touch screens as the main input and output system. For example, the famous Apple Computer's iPhone and iPod Touch, as well as a computer with a touch screen controlled by Microsoft's Windows 7 operating system.

Since the power-saving function is already a function that all electronic systems must have, all types of electronic systems have control modes that enter the power-saving mode and leave the power-saving mode.

For example, the aforementioned iPhone has a single button on the top of the body for locking the system. After pressing, the system will close the touch screen and enter the power saving mode. The iPhone also has another single button below the touch screen for unlocking the system. When the user presses a single button to unlock, the touch screen starts the display and accepts the user's input. The display screen will prompt a linear unlocking lever. When the user's single finger touches the touch screen and controls the lever to reach the reserved position, the system enters the preset desktop state. Or the user wants the system to check the numeric password, after the user presses a single button to unlock, or after the control lever reaches the reserved position, the screen displays the numeric keypad again. After the user enters the correct password through the numeric keypad, the system re-enters the preset desktop state, or the screen when it was last locked.

However, in the existing electronic system, the user cannot customize the input mode of locking and unlocking, and the unified lever unlocking mode and the numeric keypad cannot utilize various gestures and tracks that can be input by the touch screen, so There is a need for an electronic system and method of operation that can be customized to facilitate the user.

An embodiment of the invention provides an unlocking method for an electronic system having a touch screen. The unlocking method includes the steps of: accepting a trigger event in the locked state of the electronic system, turning on the touch screen, accepting a touch gesture, comparing whether the touch gesture is the same as a customized gesture, and when When the touch gesture is the same as the customized gesture, the locked state of the electronic system is released. The customized gesture is set by the user of the electronic system, rather than an unlock gesture defined by the electronic system.

The triggering event is generated by at least one of the following: a button of the electronic system, the touch screen, an acceleration sensor of the electronic system, a touch component of the electronic system that is not the touch screen, a light sensor of the electronic system, and a camera of the electronic system. The touch-off time of the touch component of the touch screen is longer than the electronic system is in an unlocked state.

The step of opening the touch screen further includes the step of prompting the user, wherein the prompt includes any combination of text, graphics, animation, and sound. The step of prompting the user includes displaying any combination of the following on the touch screen: a prompt corresponding to the customized gesture and a prompt corresponding to the unlock gesture.

The customized gesture includes at least one of the following: an absolute trajectory of a single finger moving on the touch screen and a relative trajectory of relative motion of a plurality of fingers moving on the touch screen. The customized gesture includes at least any combination of the following parameters: size, direction, time elapsed, degree of force contact, size error range, direction error range, error time range, force contact The extent of the error. The same touch gesture as the customized gesture is based on the comparison result of the above parameter combinations.

Before the unlocking state of the electronic system is released, the method further includes the following steps: prompting an additional condition; determining whether the input meets the requirement of the additional condition; and when the input meets the requirement of the additional condition, releasing the locked state of the electronic system; when the input is not In compliance with the requirements of the additional condition, it is checked whether the number of predetermined errors or a predetermined error time is exceeded; and when the predetermined number of errors or the predetermined error time is exceeded, the locked state of the electronic system is restored.

When the touch gesture is different from the customized gesture, checking whether the number of predetermined errors or a predetermined error time is exceeded, and when the predetermined number of errors or the predetermined error time is exceeded, the electronic device is returned. The locked state of the system.

After the unlocking state of the electronic system is released, the following steps are further included: replying to the screen desktop; replying to the screen before the electronic system enters the locked state; loading an original user corresponding to the customized gesture Corresponding to a computing environment; and logging out the original user and loading another computing environment corresponding to another user corresponding to the customized gesture.

a method for setting the customized gesture, the setting method comprising the steps of: accepting the customized gesture; setting a parameter of the customized gesture; verifying the customized gesture according to the parameter obtained by the setting step; setting the customization The user and/or computing environment corresponding to the gesture; and the simulation to perform the unlocking method.

Another embodiment of the present invention provides a method for setting a customized gesture for use in an electronic system having a touch screen. The setting method comprises the steps of: accepting the customized gesture; setting a parameter of the customized gesture; verifying the customized gesture according to the parameter obtained in the setting step; setting a user corresponding to the customized gesture and/ Or a computing environment; and a simulation to perform the unlocking method. The customized gesture is set by the user of the electronic system, rather than an unlock gesture defined by the electronic system.

The unlocking method includes the steps of: accepting a trigger event in the locked state of the electronic system, turning on the touch screen, accepting a touch gesture, comparing whether the touch gesture is the same as a customized gesture, and when When the touch gesture is the same as the customized gesture, the locked state of the electronic system is released. The customized gesture is set by the user of the electronic system, rather than an unlock gesture defined by the electronic system.

Yet another embodiment of the present invention provides a control device having a customized unlocking function for controlling an electronic system having a touch screen. The control device includes: a trigger receiving module for accepting a trigger event in a locked state of the electronic system; and a touch screen control module connected to the touch screen for accepting the trigger event Turning on the touch screen and accepting a touch gesture; and a computing control module for comparing whether the touch gesture is the same as a customized gesture, and whether the touch gesture is customized When the gestures are the same, the locked state of the electronic system is released.

The control device includes: a trigger receiving module for accepting a trigger event in a locked state of the electronic system; and a touch screen control module connected to the touch screen for accepting the trigger event Turning on the touch screen and accepting a touch gesture; and a computing control module for comparing whether the touch gesture is the same as a customized gesture, and whether the touch gesture is customized When the gestures are the same, the locked state of the electronic system is released. The customized gesture is set by the user of the electronic system, rather than an unlock gesture defined by the electronic system.

In order to make the features and advantages of the present invention more comprehensible, the preferred embodiments are described below, and are described in detail with reference to the accompanying drawings.

The following is a description of the embodiments of the present invention, and is intended to illustrate the basic principles of the invention and not to limit the invention. The scope of the invention is defined by the scope of the appended claims.

Please refer to FIG. 1, which is a flowchart 100 of an implementation method in accordance with an embodiment of the present invention. The process 100 is applicable to an electronic system having a touch screen that has been locked and is in a state where the touch screen is not displayed. First in step 105, the electronic system accepts a triggering event to initiate the process 100. The triggering event can be a user typing a button. Or, in order to save power in the touch screen, after the inspection time of the contact component is extended, the user touches the event triggered by the touch screen for a long time. Or the electronic system is equipped with another touch component of the non-touch screen, an event triggered when the user touches the component. Or when the electronic system is equipped with an acceleration sensor, the event triggered by the shaking is sensed by the acceleration sensor. Another example is the electronic system equipped with a light sensor or a camera, an event triggered when the captured picture or amount of light changes drastically. If the electronic system accepts events triggered by the remote or its own hardware and software, it can constitute a trigger event to which the present invention is applied.

Next, in step 110, the electronic system turns on the display device of the touch screen, and if possible, returns the check insertion time of the touch component to a normal state. Then in step 115, the user is prompted to unlock the electronic system. The so-called prompts of the present invention may include any combination of text, graphics, animation, and sound. Simply turning on the touch screen can also be considered a form of prompt, so step 115 is an optional step. The prompt may include a fixed form of prompt, such as the aforementioned linear unlocking lever, which is a preset form fixed by the electronic system. The prompt may also include a prompt set by the user. If the user sets a specific gesture to be entered, the prompt may be displayed on the touch screen. The so-called gesture of the present invention includes absolute trajectory and size direction of single or multiple fingers moving on the touch screen, relative trajectory and size direction of relative motion, and time and force contact degree of the trajectory movement and the like. . A touch gesture is accepted at step 120, and then in step 125, the touch gesture is compared to whether it is the same as a predetermined gesture. The predetermined gesture may include an unlocking gesture preset by the electronic system as described above, or may include at least one specific gesture set by the user. The so-called gestures of the present invention are the same and can have different definitions. For example, the size, direction, time, and/or force of the absolute or relative trajectory fall within an error range, which is the same. In other words, that is, any combination of the above four parameters falls within the error range, even if it is the same. The predetermined gesture here may be a customized gesture, which is customized by the process 300 shown in the third figure.

For example, when the gesture set by the user is an absolute trajectory similar to the Arabic numeral 8, it includes at least four parameters such as size, direction, time, and degree of exertion. The user has a 30% error in customizing the selected size and orientation, regardless of the time and effort required to complete the trajectory. Therefore, after the step 120 accepts the touch gesture, the electronic system is within 30% of the error between the size and direction of the touch gesture and the size and direction of the absolute track set by the user. If yes, it indicates that the touch gesture is the same as the predetermined gesture, otherwise, step 130 will be performed.

In step 130, the number of comparison errors will be compared to a predetermined number of times or times. When the number of errors exceeds a predetermined number of times, or the time since step 110 exceeds a predetermined time, step 199 is entered. At step 199, the electronic system reverts to the locked state prior to execution of the process 100. Otherwise, the flow will return to step 115. Of course, the so-called predetermined number of times and time can also be set by the user. As for the limit on the number of times and time, it can exist alone or in parallel. Step 130 can also be an optional step, and process 100 can proceed directly from step 125 to step 199.

When the result of the comparison in step 125 is the same, the following four steps 135, 150, 160, and 170 can be performed according to the user's option. Step 150 displays the desktop or environment that the electronic system subscribes to. Step 160 is to display a screen when the electronic system is locked. Step 170 is more complicated, and the user can set a plurality of predetermined gestures in advance, and each predetermined gesture can correspond to a display screen and/or load a computing environment. The load computing environment referred to in the present invention may include loading and displaying more than one program, such as dialing a phone, playing a sound, a browser, an email, a newsletter, a navigation, a map, and the like. That is, when the touch gesture is the same as the first predetermined gesture, the display email is loaded, and when the touch gesture is the same as the second predetermined gesture, the display short message is loaded. When the touch gesture is the same as the predetermined gesture of the electronic system, such as pulling the linear pull rod, step 150 or 160 is performed. Since the user can directly load different computing environments according to different gestures, it is possible to save time for the user to select an individual program after entering the desktop.

The selectively performing step 135 introduces a further protection mechanism. Since the electronic system may be at risk of being stolen or stolen, the user may choose to additionally enter step 135 from step 125 after the period of entering the locked state, prompting to use Additional testing conditions are required. For example, when the electronic system enters the locked state for a period of time, such as five minutes, the subsequent steps 150, 160, and 170 can be performed without performing step 135. When the electronic system executes the process 100 for a period of time, such as five minutes, before entering the locked state, then an additional step 135 is required. However, the user can also set this time to zero or infinitely, meaning that the step 135 will be executed forever or forever.

The present invention does not limit the additional conditions. In one example, the user may be required to type a set of passwords through a screen keyboard or a physical keyboard. In another example, the user may be required to accept biometric alignments, such as photographic, voiceprint, or fingerprint alignment of facial features. In still another example, the user may be required to make a simple mathematical operation or answer a question set in advance. Therefore, it is determined in step 140 whether the additional conditions are met, and if so, one of the subsequent steps 150, 160, and 170 can be performed in accordance with the settings. If not, the same number of errors and a predetermined number of times or times may be compared in step 145 as in step 130. When the number of errors exceeds a certain predetermined number of times, or the time since step 110 or 135 exceeds a predetermined time, step 199 is entered. Otherwise, the process can return to step 115 or 135. Step 145 can also be an optional step, and process 100 can proceed directly from step 140 to step 199.

Please refer to FIG. 2, which is an electronic system 200 in accordance with an embodiment of the present invention. The electronic system can include a touch screen 210, an input device 220, a network device 230, a processor 240, a memory 250, and a casing 260. The housing 260 can protect other components that package the electronic system 200. The processor 240 can be at least one integrated circuit, or can be a plurality of integrated circuits, coupled to the touch screen 210, the input device 220, the network device 230 and the memory 250, and used to control the connected Other components.

The memory 250 can be used to store the code required for execution by the processor 240. In the present invention, the code includes at least the code that the processor 240 can implement the process 100 shown in FIG. The input device 220 can be a device that provides a triggering event of step 105, such as a button, an acceleration sensor, a touch component, a camera, a light sensor, or any combination thereof. The input device 220 can also be a device that provides additional conditions for the step 140, such as a biometric input device, a camera, a microphone, a fingerprint scanner, etc., or any combination thereof. The network device 230 can also be a device that provides a trigger event of step 105, and can include a common wireless local area network (Wireless LAN), a personal network such as Bluetooth, and a wireless universal serial bus (Wireless Universal Serial). Bus), or wide-area access network, such as the second generation mobile communication global communication system, the third generation mobile communication code division multiple access system, the fourth generation mobile communication system.

Please refer to FIG. 3, which is a setting flow 300 of a predetermined gesture according to an embodiment of the present invention. The set gesture process 300 can be implemented in a setting program. First, in step 310, a touch gesture is accepted by the touch screen. The touch gesture can be displayed or replayed on the screen for the user to confirm. Next, in step 320, the parameters and error ranges adjusted by the user are received. The parameters mentioned here include at least the size, direction, time, and degree of exertion. The user can individually set whether to enable these parameters and their error ranges, and the electronic system can give a set of preset parameters and their preset error ranges in advance. After the user determines the parameter and its error range, the process 300 proceeds to step 330 to ask the user to input and confirm the touch gesture 330 again. An optional step 340 can then be performed to set the relevant computing environment for the touch gesture. For example, it is related to displaying the desktop, displaying the screen when locked, or selecting a set of programs for loading the display. At the end of the process 300 is also an optional step 350 in which the user can perform an unlock simulation. In other words, step 350 actually performs the process 100 shown in FIG. 1 to confirm whether the process 300 is completed. However, after the steps 150, 160, 170, and 199 in the flow 100 of the simulation are completed, it is returned to the setting program implemented according to the set gesture flow 300. When the simulation process 100 ends from steps 150, 160, 170, it indicates that the setup process 300 is successful. When the simulation process 100 is completed from step 199, it indicates that the setting process 300 is unsuccessful, and the setting program may have to be repeated once.

The above setting program can use different user interfaces to set additional conditions referred to by the process 100, such as biometric identification, password identification, an upper limit of the number of predetermined errors, and an upper limit of the predetermined error time. For the gestures stored in the electronic system, and the correspondence between gestures and related computing environments, functions such as adding, deleting, modifying, and querying can also be performed. Due to the limited space of the specification, it is not possible to exhaustively implement all the examples, and those skilled in the art should be able to understand other variations, which are within the scope of the spirit of the present invention.

Please refer to FIG. 4, which is a block diagram of an electronic system 400 according to another embodiment of the present invention.

The trigger receiving module 440, the touch screen control module 450, and the computing control module 460 may be part of the processor 240.

In an embodiment of the present invention, the related computing environment set by the processes 100 and 300 may not be limited to a certain application, or may even be a usage environment corresponding to different users. For example, after the first user inputs the gesture set by the first user, the electronic system directly logs in to the first user and displays the computing environment set by the first user. If the second user inputs the gesture set by the second user, the electronic system directly logs in to the second user and displays the computing environment set by the electronic user. This feature can be activated when the system has not logged in to any users, but enters the locked state. Or the computing environment when the electronic system is locked is the first user logged in, but the second user has a higher priority order than the first user, for example, the second user is the system administrator of the electronic system. Or supervisor. After the electronic system is unlocked, the first user can be logged out, the second user can be logged in, and the computing environment set by the user can be displayed.

In an embodiment of the invention, the processes 100 and 300 described above may be performed in the control device 430 and the processor 240.
