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 112And (6) harvesting. 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. The wireless internet access technology to which the module relates may include WLAN (wireless LAN) (Wi-Fi), Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The short-range communication module 114 is a module for supporting short-range communication. Some examples of short-range communication technologies include bluetooth^TMRadio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee^TMAnd so on.

The location information module 115 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module is a GPS (global positioning system). 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 122, 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 processed image frames may be displayed on the display unit 151. The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal. The microphone 122 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and can process such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call 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.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. 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 display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. 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. In addition to audio or video output, the alarm unit 153 may provide output in different ways to notify the occurrence of an event. 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 controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof. For a hardware implementation, the embodiments described herein may be implemented using at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a processor, a controller, a microcontroller, a microprocessor, an electronic unit designed to perform the functions described herein, and in some cases, such embodiments may be implemented in the controller 180. For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. 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.

Taking a mobile terminal of a mobile phone as an example, a situation that a user holds the mobile terminal is shown in fig. 3.

Based on the above mobile terminal hardware structure and communication system, various embodiments of the present invention are proposed.

A first embodiment of the present invention provides a mobile terminal, which provides a user with a fingerprint interaction manner using a touch screen, and can only implement fingerprint interaction on the touch screen of the mobile terminal.

Specifically, as shown in fig. 4, the mobile terminal of this embodiment includes:

the displacement detection module 40 is configured to obtain a touch electrical signal through a touch screen of the mobile terminal, determine whether the touch electrical signal is displaced in unit time, and if the touch electrical signal is displaced in unit time, obtain coordinate information of a displacement termination position; in the embodiment of the present invention, the unit time may be set to 1 to 3 seconds; the displacement occurring in a unit time may be specified as a unit displacement, which may be specified as one fifth to one third of the width of the touch screen. Of course, in practical applications, the displacement occurring in a unit time may not be a unit displacement, and the length of the displacement may be freely set and changed as required.

In practical application, when a user performs a moving operation on a touch screen of a mobile terminal, a pause may be generated when the user does not move to a displacement termination position, for example, in a payment state, the user may pause to determine whether to actually perform payment when the user performs a half of the moving operation on the touch screen of the mobile terminal, and in such a scenario, in order to ensure that the user actually completes the moving operation on the touch screen of the mobile terminal, the following technical scheme is adopted:

the displacement detection module 40 is further configured to: judging whether the time of displacement interruption is greater than or equal to a preset time threshold, and if so, determining the position of displacement interruption as a displacement termination position;

alternatively, the time threshold may be set based on empirical values.

As can be seen from the above processing, in the technical scheme of the embodiment of the present invention, whether displacement occurs is determined by detecting a sliding operation, and a displacement termination position is determined by using a time threshold, so that a subsequent fingerprint sensor triggering operation is performed.

The triggering module 41 is used for determining and triggering the corresponding fingerprint sensor according to the coordinate information of the displacement termination position;

specifically, in practical applications, the triggering module 41 needs to acquire the fingerprint sensor closest to the displacement ending position according to the coordinate information of the displacement ending position.

In practical applications, if the lengths of the two fingerprint sensors from the displacement termination position are the same, one of the fingerprint sensors may be selected to be triggered.

A plurality of fingerprint sensors 42 for analyzing fingerprint information acquired from the displacement end position after being triggered;

specifically, in the embodiment of the invention, the fingerprint sensors are arranged on the back of the whole touch screen of the mobile terminal according to the dot array, so that the fingerprint information input by a user can be identified in a full screen mode, the size and the number of the fingerprint sensors can be selected according to needs, but the fingerprint sensors are arranged in the full screen mode, that is, if the working range of a single sensor is large, the number of the sensors can be reduced, and if the working range of the single sensor is small, the number of the sensors needs to be increased, so as to meet the requirements.

When the fingerprint sensor analyzes the fingerprint, the acquired fingerprint information is compared with the fingerprint information input by the user in advance, so that an analysis result is obtained. The analysis result indicates that: successful fingerprint matching or failed fingerprint matching.

And an operation module 43, configured to determine whether to perform an interactive operation of the function corresponding to the moving termination position according to the analysis result of the fingerprint sensor on the fingerprint information.

That is, if the analysis result of the fingerprint sensor indicates that the fingerprint matching is successful, the interactive operation of the function corresponding to the shift ending position is allowed to be executed, and conversely, if the analysis result of the fingerprint sensor indicates that the fingerprint matching is failed, the interactive operation of the function corresponding to the shift ending position is prohibited to be executed, and a prompt indicating that the fingerprint matching is failed can be given, and the user can be instructed to perform the fingerprint matching again.

In practical applications, the function and the operation mode corresponding to the displacement termination position are prompted to the user on the touch screen, for example, the function corresponding to the position is payment confirmation, the operation mode is sliding to the position through the touch screen, or the function corresponding to the position is authorization operation, the operation mode is sliding to the position through the touch screen, or the function corresponding to the position is unlocking operation, the operation mode is sliding to the position through the touch screen, and so on.

Function prompt is carried out on the user through the touch screen, the user can be prevented from learning when fingerprint interaction is carried out, and what operation can be carried out at a glance and what function is executed by the operation can be avoided. The operation of the user is facilitated, and the use experience of the user is improved.

The above-described embodiments will be described below by way of examples.

In a certain APP account transfer interactive interface, when a user inputs the amount of money to be transferred and an object to be transferred, after the two operations are completed, the user only needs to press down the touch screen, then the displacement is carried out within a preset unit time, the displacement is continued and stopped within 1 second (the time threshold for judging the stop of the displacement is 3 seconds) in the displacement process, the fingerprint identification cannot be triggered when the displacement is suspended, the fingerprint identification can be triggered after the displacement is really stopped, and after the fingerprint identification is correct, the corresponding function (namely the payment identification or the payment confirmation) is completed according to the function (namely the payment verification or the payment confirmation) of the interactive unit where the mobile termination position is located.

In a second embodiment of the present invention, a mobile terminal is provided, where the mobile terminal provides a user with a fingerprint interaction manner using a touch screen, and the fingerprint interaction can be implemented only on the touch screen of the mobile terminal.

In practical application, when a user performs a moving operation on a touch screen of a mobile terminal, a pause may be generated when the user does not move to a displacement termination position, for example, in a payment state, the user may pause to determine whether to actually perform payment when the user performs a half of the moving operation on the touch screen of the mobile terminal, and in such a scenario, in order to ensure that the user actually completes the moving operation on the touch screen of the mobile terminal, a technical scheme different from that of the first embodiment is adopted:

the displacement detection module 40 is further configured to: and judging whether the displacement termination position is in the target area, and if so, determining that the target area is the displacement termination position.

In this embodiment, the position of the target area, the operation of reaching the target area, and the function of the target area are indicated in the touch screen. Therefore, the target area is set for the user to be very instructive, the end position of the displacement required by the user is clearly indicated, and the fingerprint sensor can be triggered only when the displacement is transferred to the target area, so that the possibility of misoperation of the user is further reduced, and the operation of the user is quicker and simpler.

As can be seen from the above processing, in the technical solution of the embodiment of the present invention, whether a displacement occurs is determined by detecting a sliding operation, and a displacement termination position is determined by whether the displacement occurs in a target region, so that a subsequent fingerprint sensor triggering operation is performed.

And an operation module 43, configured to determine whether to perform an interactive operation of the function corresponding to the displacement termination position according to an analysis result of the fingerprint information by the fingerprint sensor.

That is, if the analysis result of the fingerprint sensor indicates that the fingerprint matching is successful, the interactive operation of the function corresponding to the displacement ending position is allowed to be executed, and conversely, if the analysis result of the fingerprint sensor indicates that the fingerprint matching is failed, the interactive operation of the function corresponding to the displacement ending position is prohibited to be executed, and a prompt indicating that the fingerprint matching is failed can be given, and the user can be instructed to perform the fingerprint matching again.

The above-described embodiments will be described below by way of examples.

In a certain APP account transfer interactive interface, when a user inputs the amount of money to be transferred and an object to be transferred, after the two operations are completed, the user only needs to press down the touch screen, then the displacement is carried out within a preset unit time, the displacement process is not stopped in a target area, fingerprint identification cannot be triggered, after the fingerprint identification is really displaced to the target area, the fingerprint identification can be triggered, and after the fingerprint identification is correct, the corresponding function (namely payment identification or payment confirmation) is completed according to the function (namely payment verification or payment confirmation) of an interactive unit where a mobile termination position is located.

In the third embodiment of the present invention, a mobile terminal is further provided, where the mobile terminal provides a way for a user to perform fingerprint interaction by using a touch screen, and the fingerprint interaction can be implemented only on the touch screen of the mobile terminal.

In practical applications, when a user performs a moving operation on a touch screen of a mobile terminal, a pause may be generated when the user does not move to a displacement termination position, for example, in a payment state, the user may pause to determine whether to actually perform payment when the user performs a half of the moving operation on the touch screen of the mobile terminal, and in such a scenario, in order to ensure that the user actually completes the moving operation on the touch screen of the mobile terminal, the following manner may be adopted:

the displacement detection module 40 is further configured to: and judging whether the time of displacement interruption is greater than or equal to a preset time threshold, if so, determining that the position of displacement interruption is a displacement termination position, then, judging whether the displacement termination position is in a target area, and if so, determining that the target area is the displacement termination position.

Alternatively, the time threshold may be set based on empirical values.

That is to say, in this embodiment, the displacement termination position is determined according to the time threshold and the two parameters of whether the displacement termination position is located in the target area, so that the problem that the user pauses when the touch screen is in sliding operation is solved, the user can be clearly prompted about the position to which the user needs to slide, and the fingerprint sensor can be triggered only when the displacement is located in the target area, so that the possibility of misoperation of the user is further reduced, and the operation of the user is faster and simpler.

It can be seen from the above processing that, in the technical solution of the embodiment of the present invention, whether a displacement occurs is determined by detecting a sliding operation, and the displacement termination position is determined by using a time threshold and a target region, so that a subsequent fingerprint sensor triggering operation is performed.

The above-described embodiments will be described below by way of examples.

In a certain APP transfer interaction interface, a user is prompted in a target area to: when a user inputs the amount of money to be transferred and the object to be transferred, the user only needs to press down the touch screen after completing the two operations, then performs displacement within a preset unit time, continues to perform displacement and stops in a target area after stopping for 1 second (the time threshold for judging the stop of the displacement is 3 seconds) in the displacement process, does not trigger fingerprint identification when the displacement is stopped temporarily, can trigger the fingerprint identification after the displacement really stops in the target area, and completes the corresponding function (namely completing payment verification or payment confirmation) according to the function (namely completing the payment verification or the payment confirmation) of the interaction unit where the movement termination position is located after the fingerprint identification is correct.

In a fourth embodiment of the present invention, a mobile terminal is provided, where the mobile terminal provides a user with a fingerprint interaction manner using a touch screen, and the fingerprint interaction can be implemented only on the touch screen of the mobile terminal.

In addition, the displacement detection module 40 needs to determine whether the start position and the displacement trajectory of the displacement are within the specific interaction area, and if so, acquires the coordinate information of the displacement end position.

Alternatively, the time threshold may be set based on empirical values.

That is to say, in this embodiment, the displacement termination position is determined according to the time threshold and the two parameters of whether the displacement termination position is located in the target area, so that not only is the problem that the user pauses when the touch screen slides is solved, but also the position to which the user needs to slide can be clearly prompted to the user, and meanwhile, misoperation of the user is avoided.

In addition, in this embodiment, a clear indication may be given to the start position and the displacement trajectory of the displacement, and whether the user needs to perform the fingerprint identification operation is determined by determining whether the start position and the displacement trajectory of the displacement are within the specific interaction region, so that the possibility of the fingerprint identification misoperation is completely avoided, and a more detailed prompt is given to the user to guide the fingerprint identification operation of the user.
