More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.
The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit may include at least one of a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115.
The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast management server via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may be a server that generates and transmits a broadcast signal and/or broadcast associated information or a server that receives a previously generated broadcast signal and/or broadcast associated information and transmits it to a terminal. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and the like. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. The broadcast associated information may also be provided via a mobile communication network, and in this case, the broadcast associated information may be received by the mobile communication module 112. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video broadcasting-handheld (DVB-H), and the like. The broadcast receiving module 111 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 111 may receive a broadcast signal by using a signal such as multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO)@) A digital broadcasting system of a terrestrial digital broadcasting integrated service (ISDB-T), etc. receives digital broadcasting. The broadcast receiving module 111 may be constructed to be suitable for various broadcasting systems that provide broadcast signals as well as the above-mentioned digital broadcasting systems. The broadcast signal and/or broadcast associated information received via the broadcast receiving module 111 may be stored in the memory 160 (or other type of storage medium).
The mobile communication module 112 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.
The wireless internet module 113 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal.

According to the current technology, the GPS module 115 calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS module 115 can calculate speed information by continuously calculating current position information in real time.
The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 1220, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode.

The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.
The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.
The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device.

In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.
In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153, and the like.

The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.
The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.
The alarm unit 153 may provide an output to notify the mobile terminal 100 of the occurrence of an event. Typical events may include call reception, message reception, key signal input, touch input, and the like.

For example, the alarm unit 153 may provide an output in the form of vibration, and when a call, a message, or some other incoming communication (incomingmunication) is received, the alarm unit 153 may provide a tactile output (i.e., vibration) to inform the user thereof. By providing such a tactile output, the user can recognize the occurrence of various events even when the user's mobile phone is in the user's pocket. The alarm unit 153 may also provide an output notifying the occurrence of an event via the display unit 151 or the audio output module 152.
The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.
The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.
The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 1810 for reproducing (or playing back) multimedia data, and the multimedia module 1810 may be constructed within the controller 180 or may be constructed separately from the controller 180.

The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in the memory 160 and executed by the controller 180.
Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.
The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.
A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.
Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.
Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 2750.
Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).
The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.
As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.
In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.
As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.
Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method.

The edge interaction area achieves the purpose of acquiring the sliding touch operation applied to the edge interaction area through the sensors arranged above, and the effectiveness of the sliding touch operation is identified through matching the acquired sliding touch operation with the sliding touch operation prestored in the sliding touch operation database. In addition to comparing with the sliding touch operation database to identify the effectiveness of the sliding touch operation applied to the edge interaction area, the method may also be performed by comparing with a preset touch rule to confirm, or may be performed by using other feasible methods in the prior art to identify the sliding touch operation.
In the invention, the terminal screen is vertically arranged and is over against the user as a reference position for defining the directional words such as up, down, left, right, front and back.
In order to effectively control touch operation, after the screen is lightened, the system presumes that a user needs to input an unlocking password to unlock the terminal, and then, whether interactive touch operation exists in the edge interactive area or not is monitored.
A sliding touch operation refers to a continuous touch track from a finger falling on a starting point of the edge interaction area to a terminal point of the edge interaction area. For example, a sliding motion from bottom to top and a sliding motion from left to right are both a sliding touch operation. In this embodiment, the sliding touch operation includes sliding in the edge interaction area from the bottom to the top in a longitudinal direction to exceed a preset length, and sliding in the edge interaction area from the top to the bottom in a longitudinal direction to exceed a preset length. The set length is preferably 20% of the long side of the screen. In the invention, the screen is rectangular, and the long edge of the screen refers to the length of the screen on one side of the edge interaction area, preferably the length of the left side or the right side of the screen.
The time interval between the sliding touch control operations applied to the edge interaction area in sequence is within the set time length. The plurality of sliding touch operations are at least two sliding touch operations, preferably four sliding touch operations. For example, 1 second is a set duration, a sliding motion from bottom to top is performed first, then a motion from top to bottom is performed within 1 second, the following sliding touch operation can be regarded as an effective sliding touch operation continuing the previous touch operation, otherwise, even if the motion of the touch operation is consistent with the preset motion, the system can consider that the password input is finished, and directly enter the next preset value acquisition and calculation.
S102, sequentially acquiring preset values corresponding to all sliding touch operations according to the mapping relation between the preset sliding touch operations and the preset values; displaying the acquired preset value on a screen;
each preset unlocking sliding touch operation corresponds to a preset value, the preset value can be changed through a terminal, and for the simplicity of calculation and memory, the preset value is a preferable integer, and can be a positive number or a negative number. For example, preset sliding touch operation: sliding the screen from bottom to top for more than 20% of the long edge of the screen, and setting a preset value of 2; slide from top to bottom over 20% of the long side of the screen, set preset value 5.
In order to enable a user to clearly judge whether the input sliding touch operation is accepted as effective or not and reduce the memory difficulty, when the sliding touch operation in the input edge interaction area is successfully identified, displaying a preset value corresponding to the identified sliding touch operation in a screen range; if the corresponding preset sliding touch operation is not found in the sliding touch operation of the input edge interaction area, no preset value is displayed, the preset value is displayed on the screen for a set time duration, for example, 1 second, and the displayed sequence of the preset values is the input sequence of the identified sliding touch operation.
S103, performing addition operation on the acquired preset value corresponding to the sliding touch operation;
when the input sliding touch operation is carried out in the edge interactive area of the terminal, the input sliding touch operation is divided into effective touch operation and invalid touch operation, the effective sliding touch operation means that the input sliding touch operation is the sliding touch operation which accords with a preset touch rule or corresponds to the preset sliding touch operation, when the current input sliding touch operation is invalid and the previous input sliding touch operation cannot be unlocked, the unlocking is finished, the previously input sliding touch operation is reset, the input unlocking sliding touch operation is re-identified, when the input sliding touch operation is all effective and no new sliding touch operation is received, preset values corresponding to all the sliding touch operations are sequentially obtained and addition operation is carried out, the input password value is obtained, and the next step of judging whether the password is correct is carried out.
S104, judging whether the result of the addition operation is the same as a preset password value or not;
if the obtained password value is the same as the preset password value, unlocking the screen; and if not, ending.
That is, when the password value input by the user is the same as the preset password value, the terminal performs unlocking, otherwise, the terminal does not perform unlocking.
For example, the preset password value is 12, the touch input action needs to slide from top to bottom twice and slide from bottom to top once, when the user needs to unlock, the screen is lighted up, then the screen slides from top to bottom over 20% of the long edge of the screen once in the edge interaction area, the finger leaves, then (within the set time) the sliding touch operation of sliding from bottom to top over 20% of the long edge of the screen is performed again, the finger leaves, and then (within the set time) the sliding touch operation of sliding from top to bottom over 20% of the long edge of the screen is performed again; and all the three sliding touch operations are recognized as effective sliding touch operations, and the interval between every two adjacent sliding touch operations meets the range requirement of the set time, so that the system recognizes that 5, 2 and 5 are input by the user, obtains an input password value 12 after executing 5+2+5, compares the input password value with the preset password value 12, determines that the input password is correct, and unlocks the terminal. The user can select 2, 5 or 5, 2 or 5, 2, 5 corresponding to the sliding touch operation sequence every time the password is input, so that the variability of password input is increased, and the difficulty of password snooping and learning is increased.
According to the terminal unlocking method, the plurality of continuous sliding touch operations are acquired in the edge interaction area of the terminal, the preset values corresponding to the acquired sliding touch operations are calculated, and the sum of the preset values is used as the input password value, so that the terminal is unlocked.
Example two
A second embodiment of the present invention provides a terminal unlocking method, as shown in fig. 4, including the following steps:
s201, after the screen is lighted, obtaining a continuous pressing point of an edge interaction area on one side of the terminal, and forming an edge interaction area which is independent from top to bottom by using the edge interaction area on the two sides of a horizontal coordinate line secant of the point, wherein the horizontal coordinate line is parallel to a short edge of the terminal.
The continuous pressing point is a continuous pressing point which is identified when the time for pressing a certain point in the edge interaction area exceeds a set time, for example, the continuous pressing time is more than 2 seconds; for example, when a user holds the mobile phone screen with one hand and faces the user, the thumb presses on one side edge of the terminal, and the fingers press on two side edges, the thumb pressing point is a continuous pressing point, and if one continuous pressing point exists on two sides at the same time, the detection is finished.
In order to further enhance the complexity of the password, the digit of the password is increased, the edge interaction area is partitioned, and each partition can be used as an independent edge interaction area to acquire the input sliding touch operation. The partition mode may be a fixed partition, for example, the edge interaction area is divided into two, three, and four areas on average; dynamic partitioning can be performed, the dynamic partitioning can better adapt to the situation that fingers are located at different positions when a user holds the mobile phone, so that the fingers can conveniently touch the partitions no matter where the fingers are located, and the input of sliding touch operation is facilitated.
Specifically, the dynamic partition mode of the edge interaction area is as follows: the continuous pressing point of the edge interaction area on one side of the terminal is obtained, the edge interaction areas on two sides are divided into two independent edge interaction areas by taking the abscissa line of the point as a dividing line, and the abscissa line is parallel to the short side of the terminal.
In order to facilitate the touch operation of each divided independent edge interaction area, the continuous pressing point is preferably located in the range of 60% of the area in the middle of the long side of the screen, and 20% of the area is left at each end of the screen and is not used as the detection area of the continuous pressing point.
Generally speaking, after a user lights a screen to enter a prompt unlocking page, continuous pressing is carried out in any side edge interaction area, after the system identifies the continuous pressing point, the edge interaction areas on two opposite sides are divided into an upper edge interaction area and a lower edge interaction area by the abscissa line of the continuous pressing point, 4 independent edge interaction areas exist on two sides in total, and each edge interaction area has the same function of identifying sliding touch operation of the user. And inputting a preset sliding touch operation in the corresponding edge interaction area to unlock.
Under the special single-hand operation condition, for example, when the mobile phone is held by the left hand, the thumb is located at the left side edge of the terminal screen, and the other four fingers are located at the right side edge of the terminal screen, wherein in order to stably hold the terminal, especially for the currently widely used large-screen mobile phones, the positions of the thumb and the index finger or the positions of the thumb and the middle finger are often located at approximately the same horizontal position, the system identifies the position coordinates of the thumb and divides the edge interaction areas at the two sides by the abscissa line, and the index finger, the ring finger and the like located at the opposite side of the thumb perform sliding touch operation in the respective adjacent edge interaction areas, so that the.
The process of partitioning and unlocking is described as follows, for example, as shown in fig. 7:
the terminal screen has the upper left end point as the origin of coordinates (0,0), the terminal screen has the length b and the width a, namely the coordinates of the top right end point are (a, 0), the coordinates of the bottom left end point are (0, b), and the coordinates of the bottom right end point are (a, b). And (3) cutting the middle 60% area from (0,1/5b) to (0,4/5b) on the left edge interaction area to be used as a pressable area of a left pressing point, and selecting the upper reserved 20% area and the lower reserved 20% area to have corresponding operation areas for subsequent right sliding.
When a user lights the screen to unlock, the system monitors whether one continuous pressing point exists in an edge interaction area on one side, and if so, the user is presumed to need to unlock. For example, when a user holds the mobile phone with the left hand, the thumb is located at the left edge of the terminal screen, the other four fingers are located at the right edge of the terminal screen, the system monitors the point and recognizes the coordinates of the point as (0, X) when the thumb of the user continuously presses the left edge interaction area, then the system divides the two side edge interaction areas into an upper edge interaction area and a lower edge interaction area respectively by taking an X horizontal line as a boundary, and simultaneously monitors the sliding touch operation of the two independent edge interaction areas at the right side.
S202, identifying a plurality of sliding touch operations in the edge interaction area;
specifically, the definition of the edge interaction area refers to the first embodiment.
The two independent edge interaction areas can independently identify sliding touch operation input by a user, the input time of two adjacent sliding touch operation is within a set time length, and when the sliding touch operation input by exceeding the set time length cannot be decrypted, the sliding touch operation input by the front is abandoned, and the sliding touch operation input by the back is used as new sliding touch operation for decryption.
In order to enable a user to clearly judge whether the input sliding touch operation is accepted as effective and help the user to reduce the memory difficulty, if the sliding touch operation in the edge interaction area is successfully identified, a preset value corresponding to the identified sliding touch operation is directly displayed in a screen range; and if the sliding touch operation of the input edge interaction area does not find the corresponding preset sliding touch operation, no preset value is displayed. The preset values are displayed on the screen for a set time duration, for example, 1 second, and the sequence of displaying the preset values is the input sequence of the identified sliding touch operation.
For example: the system recognizes that the user slides upwards from the left touch point (0, x) corresponding to the right position (a, x) and exceeds 20% of the long edge of the screen, and if the distance reaches (a, x-1/5b) or more, the user is considered to slide upwards from the original point of the upper partition once and is marked as A; displaying a corresponding preset value on a screen;
then, the system recognizes that the user slides downwards from the left touch point to the right position (a, x) and exceeds 20% of the long edge of the screen to reach (a, x +1/5B) or above, and then determines that the user slides downwards from the origin in the lower partition once, which is marked as B; displaying a corresponding preset value on a screen;
then, the system recognizes that the user slides upwards from the lower partition below the position (a, x) corresponding to the left touch point and more than 20% of the long side of the screen below the position (a, x +1/5b) and more than (a, x), and then determines that the user slides upwards once in the lower partition and marks as C; displaying a corresponding preset value on a screen;
then, the system recognizes that the user slides downwards from the position (a, x-1/5b) above the right position (a, x) corresponding to the left touch point by more than 20% of the long edge of the screen, namely, the position (a, x-1/5b) above slides downwards by more than (a, x), and then the user is considered to slide downwards once in the upper partition and is marked as D; displaying a corresponding preset value on a screen;
s203, sequentially acquiring preset values corresponding to the sliding touch operations according to the mapping relation between the preset sliding touch operations and the preset values, and displaying the acquired preset values on a screen;
each preset sliding touch operation corresponds to a preset value, the preset value can be changed through a terminal, and for the simplicity of calculation and memory, the preset value is a preferable integer, and can be a positive number or a negative number.
Assume that the user defines at encryption: the cipher value M is 16, and the edge interaction area is dynamically divided into an upper edge interaction area and a lower edge interaction area which are independent. Predefining an upper partition: the sliding touch operation sliding from bottom to top corresponds to a preset value A being 7, the sliding touch operation sliding from top to bottom corresponds to a preset value B being-1, and the lower partition is predefined: the sliding touch operation sliding from bottom to top corresponds to a preset value C which is-2, and the sliding touch operation sliding from top to bottom corresponds to a preset value D which is 5;
the user has multiple choices when unlocking, wherein M is selected to be A + D + D + B;
the user operation process comprises the following steps: pressing the left screen, sliding upwards at the right origin, then sliding downwards, releasing the hand, sliding downwards again, continuously sliding downwards to cross the origin until the position below the origin exceeds 20% of the long edge of the screen, and releasing the left touch point; and the precedence relationship of the sliding touch operation of each unlocking path has no requirement, and a user only needs a mental simple addition and subtraction method when unlocking, so that the password of the user can be ensured to be temporarily changed every time, but the password is easier to remember.
S204, performing addition operation on the acquired preset value corresponding to the sliding touch operation;
adding the preset values of the sliding touch operation input above, namely, a + D + B is 7+5+5-1 is 16
S205, judging whether the result of the addition operation is the same as a preset password value or not; if the two are the same, unlocking the terminal screen; and if not, ending.
The system judges that the addition result of the preset value of the input sliding touch operation is 16, is the same as the preset password value M which is 16, and has the same numerical value, and executes unlocking.
According to the terminal unlocking method, dynamic partitioning is carried out on the edge interaction area of the terminal, so that more digits of the password can be input into the edge interaction area of the terminal, the password safety is further enhanced, in addition, the dynamic partitioning mode is more suitable for the actual situation of position change when people hold the mobile terminal, the password input is more smooth, and the user experience is better.

The time interval between two adjacent sliding touch operations in the plurality of sliding touch operations is within a set time length. The plurality of sliding touch operations are at least two sliding touch operations. For example, 1 second is a set duration, a sliding motion from bottom to top is performed first, and then a next sliding touch operation needs to be performed within 1 second.

The terminal performs unlocking if the password value calculated by the execution unit 40 is the same as the preset password value, and does not perform unlocking if the password value calculated by the execution unit 40 is different from the preset password value.
For example, the preset password value is 12, the touch input action needs to slide from top to bottom twice and slide from bottom to top once, when the user needs to unlock, the screen is lighted up, then the screen slides from top to bottom over 20% of the long edge of the screen once in the edge interaction area, the finger leaves, then (within the set time) the sliding touch operation of sliding from bottom to top over 20% of the long edge of the screen is performed again, the finger leaves, and then (within the set time) the sliding touch operation of sliding from top to bottom over 20% of the long edge of the screen is performed again; and all the three sliding touch operations are recognized as effective sliding touch operations, and the interval between every two adjacent sliding touch operations meets the range requirement of the set time, so that the system recognizes that 5, 2 and 5 are input by the user, obtains an input password value 12 after executing 5+2+5, compares the input password value with the preset password value 12, determines that the input password is correct, and unlocks the terminal. The user can select 2, 5 or 5, 2 or 5, 2, 5 corresponding to the sliding touch operation sequence every time the password is input, so that the variability of password input is increased, and the difficulty of password snooping and learning is increased.
According to the terminal unlocking device, the plurality of continuous sliding touch operations are acquired in the edge interaction area of the terminal, the preset value corresponding to the acquired sliding touch operation is calculated to calculate the password value, so that the terminal is unlocked, the operation mode has certain secrecy, the sequence of the sliding touch operations in the operation process can be changed, other people are difficult to know the password, and the password security is better than that of the prior art.

The instruction obtaining unit 10, the prompting unit 50, the default value reading unit 20, the calculating unit 30, and the executing unit 40 are the same as those in the embodiment, and are not described herein again.
And the area dividing unit 60 is configured to obtain a continuous pressing point of the edge interaction area on one side of the terminal after the screen is lit, and divide the edge interaction areas on the two sides by using a horizontal coordinate line of the point to form vertically independent edge interaction areas, where the horizontal coordinate line is parallel to the short edge of the terminal.
The continuous pressing point is a continuous pressing point which is recognized when the time for pressing a certain point in the edge interaction area exceeds a set time, for example, the continuous pressing time is more than 2 seconds.
In order to further enhance the complexity of the password, the digit of the password is increased, the edge interaction area is partitioned, and each partition can be used as an independent edge interaction area to acquire the input sliding touch operation. The partition mode may be a fixed partition, for example, the edge interaction area is divided into two, three, and four areas on average; dynamic partitioning can be performed, the dynamic partitioning can better adapt to the situation that fingers are located at different positions when a user holds the mobile phone, so that the fingers can touch the partitions no matter where the fingers are located, and the input of sliding touch operation is facilitated.
Specifically, the dynamic partition mode of the edge interaction area is as follows: the continuous pressing point of the edge interaction area on one side of the terminal is obtained, the area dividing unit 60 divides the edge interaction area on the two sides into an upper edge interaction area and a lower edge interaction area by taking the abscissa line of the point as a dividing line, namely, four edge interaction areas exist in total and can input an interactive touch command, and the abscissa line is parallel to the short side of the terminal.
Preferably, the identification region of the continuous pressing point is located in the middle set region of the screen, preferably in the middle 60%, and the regions of 20% at both ends of the screen are not used as detection regions of the continuous pressing point.
Generally, after a user lights a screen to enter a prompt unlocking page, continuous pressing is performed in any edge interaction area, after the system identifies the continuous pressing point, the edge interaction areas on two opposite sides are divided into two independent edge interaction areas by the abscissa line of the continuous pressing point, and the two independent edge interaction areas have the same function of identifying the sliding touch operation of the user. And inputting a preset sliding touch operation in the corresponding edge interaction area to unlock.
Under the special single-hand operation condition, for example, when the mobile phone is held by the left hand, the thumb is located at the left side edge of the terminal screen, and the other four fingers are located at the right side edge of the terminal screen, wherein in order to stably hold the terminal, especially for the currently widely used large-screen mobile phones, the positions of the thumb and the index finger or the positions of the thumb and the middle finger are often located at approximately the same horizontal position, the system identifies the position coordinates of the thumb and divides the edge interaction areas at the two sides by the abscissa line, and the index finger, the ring finger and the like located at the opposite side of the thumb perform sliding touch operation in the respective adjacent edge interaction areas, so that the.
The process of partitioning and unlocking is described as follows, for example, as shown in fig. 7:
the terminal screen has the upper left end point as the origin of coordinates (0,0), the terminal screen has the length b and the width a, namely the coordinates of the top right end point are (a, 0), the coordinates of the bottom left end point are (0, b), and the coordinates of the bottom right end point are (a, b). And (3) cutting the middle 60% area from (0,1/5b) to (0,4/5b) on the left edge interaction area to be used as a pressable area of a left pressing point, and selecting the upper reserved 20% area and the lower reserved 20% area to have corresponding operation areas for subsequent right sliding.
When a user lights the screen to unlock, the system can preferentially judge whether touch operation is monitored in the area, and if yes, the user needs to unlock. Under the precondition that the user presses the left corresponding area, the coordinate point of the continuous touch point on the left side of the user is assumed to be (0, X), the system uses the X horizontal line as a boundary to divide the edge interactive area into an upper edge interactive area and a lower edge interactive area, and the operation of the right edge of the screen is monitored.
Each partition can independently identify the sliding touch operation input by a user, the input time of two adjacent sliding touch operations is within a set time length, the sliding touch operation input by exceeding the set time length is abandoned, and the sliding touch operation input at the front is used as the initial first sliding touch operation.

then, the system recognizes that the user slides downwards from the left touch point to the right position (a, x) and exceeds 20% of the long edge of the screen to (a, x +1/5B) or above, and then determines that the user slides downwards from the original point in the lower partition once, and marks the original point as B, and displays the corresponding preset value on the screen;
then, recognizing that the user slides upwards from the left touch point to the position (a, x) which is more than 20% of the long edge of the screen below the right position (a, x +1/5b), namely the lower partition below (a, x +1/5b), determining that the user slides upwards once in the lower partition, and marking the position as C, and displaying the corresponding preset value on the screen;
then, the system recognizes that the user slides downwards from the position (a, x-1/5b) above the right position (a, x) corresponding to the left touch point to exceed the position (a, x) of the long edge of the screen by more than 20%, and then determines that the user slides downwards once in the upper partition, and records the position as D, and displays the corresponding preset value on the screen;
