In order to solve the above problem, a method for adjusting the sensitivity of a touch screen is provided in the related art, in which a timer starts to time after a trigger instruction is acquired when the touch screen is in an activated state, and when the time length counted by the timer reaches a predetermined value, the sensitivity of the touch screen is adjusted to enter the next sensitivity level, thereby adjusting the sensitivity of the touch screen.

The mobile terminal 100 may include a wireless communication unit 110, an a/V (audio/video) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, and a power supply unit 190, etc.
Fig. 1 illustrates the mobile terminal 100 having various components, but it is to be understood that not all illustrated components are required to be implemented. More or fewer components may alternatively be implemented. The elements of the mobile terminal 100 will be described in detail below.
The wireless communication unit 110 may generally include 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 110 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 digital broadcasting by using a digital broadcasting system such as a data broadcasting system of multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO @), terrestrial digital broadcasting integrated service (ISDB-T), and the like. 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 (TM), Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee (TM), and the like.
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 115 is a GPS (global positioning system). According to the current technology, the GPS 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 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 100. The microphone 122 may receive sounds (audio data) via the microphone 122 in a phone call mode, a recording mode, a voice recognition mode, or the like, and is capable of processing 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 to control various operations of the mobile terminal 100 according to a command input by a user. 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 sensing unit 140 may include a proximity sensor 141.
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 100 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 100. Various command signals or power input from the cradle may be used as a signal for identifying whether the mobile terminal 100 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, mobile terminal 100 may include two or more display units (or other display devices), for example, mobile terminal 100 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 100 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 (communicating communication) 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 181 for reproducing (or playing back) multimedia data, and the multimedia module 181 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.

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, the mobile terminal 100 has been described in terms of its functionality. In addition, the mobile terminal 100 in the embodiment of the present invention may be a mobile terminal such as a folder type, a bar type, a swing type, a slide type, and other various types, and is not limited herein.
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, a CDMA wireless communication system may include a plurality of intelligent terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC 280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC 280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul line may be constructed according to any of several known interfaces, which may include, for example, european/american standard high capacity digital lines (E1/T1), Asynchronous Transfer Mode (ATM), network protocol (IP), point-to-point protocol (PPP), frame relay, high-rate digital subscriber line (HDSL), Asymmetric Digital Subscriber Line (ADSL), or various types of digital subscriber lines (xDSL). It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.
Each BS 270 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 BS 270 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 BS 270 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 partition of a particular BS 270 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 location information module 115 (e.g., GPS) as shown in fig. 1 is generally configured to cooperate with the 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 BS 270 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 is processed within a 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 MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC 280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS 270 to transmit forward link signals to the mobile terminal 100.
Based on the above mobile terminal, an embodiment of the present invention provides a touch method for a touch screen, and fig. 3 is a flowchart of the touch method for the touch screen according to the embodiment of the present invention, as shown in fig. 3, the method includes the following steps:

step S304, determining the sensitivity of the detected fingerprint information according to the preset corresponding relation between the fingerprint information and the touch sensitivity;
step S306, executing the operation corresponding to the touch signal on the touch screen according to the sensitivity of the detected fingerprint information.
Through the steps, the fingerprint information corresponding to the touch signal received through the touch screen is obtained, the sensitivity of the detected fingerprint information is determined according to the preset corresponding relation between the fingerprint information and the touch sensitivity, the operation corresponding to the touch signal is executed on the touch screen according to the sensitivity of the detected fingerprint information, the problem that misoperation is easily caused due to different sensitivities of different fingers in the related technology is solved, the operation is triggered according to different sensitivities, the possibility of misoperation is effectively reduced, and the user experience is improved.
The sensitivity of the touch edges of different fingers is different, the lower sensitivity requires shorter trigger distance, and the fingers with higher sensitivity need longer trigger distance to be difficult to mistakenly touch. Detecting which finger of the five fingers the finger on the edge of the user touch terminal device is (utilizing the ultrasonic module to carry out three-dimensional imaging); the effective areas of the edge triggering gestures of different finger touch edges are different (S thumb > S forefinger > S middle finger > S ring finger > S tail finger). The user extracts a fingerprint of each finger input, and designates the fingerprint as a fingerprint of a certain finger when inputting the fingerprint. The subsequent screen (the screen with the ultrasonic module stereo imaging function) detects the fingerprint input by the user, then judges which finger the fingerprint is, and triggers the edge gesture operation according to the sensitivity of the finger.
Before acquiring fingerprint information corresponding to a touch signal received through a touch screen, acquiring fingerprint information of each finger, including: and synthesizing a plurality of fingerprint information of each finger, which are acquired for a plurality of times, to generate fingerprint information corresponding to each finger, and setting the corresponding relation between the fingerprint information of each finger and the touch sensitivity.

If the finger presses the time in the two judgments, the collected image is an effective fingerprint image, if the finger does not press the time in the two judgments, the collected image is probably not an effective fingerprint image, if the finger presses the time in the one time, the collected image is probably incomplete, and the finger presses the time in the two judgments, so that whether the collected fingerprint image is effective or not can be determined, the recognition rate is relatively high, and the user experience is good. Fig. 5 is a schematic diagram of setting a corresponding relationship between fingerprint information and touch sensitivity according to an embodiment of the present invention, and as shown in fig. 5, after acquiring fingerprint information, fingerprint information of each finger is generated in a corresponding relationship table, and then sensitivity is set for each finger according to user input, and when a setting completion instruction is received, setting of the corresponding relationship between fingerprint information and touch sensitivity is completed and stored.
