It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A mobile terminal 100 implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.

The mobile terminal may be implemented in various forms. For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like, and a stationary terminal such as a digital TV, a desktop computer, and the like. In the following, it is assumed that the terminal is a mobile terminal. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.

Fig. 1 is a schematic hardware configuration of a mobile terminal implementing various embodiments of the present invention.

More or fewer components may alternatively be implemented. The elements of the mobile terminal 100 will be described in detail below.

The sensing unit 10 serves to detect 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 respect to 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 to generate 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 10 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 10 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device.

The wireless communication unit 40 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, a mobile communication module, a wireless internet module, a short-range communication module, and a location information module.

The broadcast receiving module 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. 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 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 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 may be constructed to be suitable for various broadcasting systems providing broadcast signals as well as the above-mentioned digital broadcasting system. The broadcast signal and/or broadcast associated information received via the broadcast receiving module may be stored in the memory 20 (or other type of storage medium).

The mobile communication module 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 short-range communication module 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 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 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 can calculate speed information by continuously calculating current position information in real time.

When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 51 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 51 and the touch panel are superimposed on each other in the form of layers to form a touch screen, the display unit 51 may function as an input device and an output device. The display unit 51 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 52 may convert audio data received by the wireless communication unit 40 or stored in the memory 20 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.

For example, the alarm unit 53 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 53 may provide a tactile output (i.e., vibration) to notify 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 53 may also provide an output notifying the occurrence of an event via the display unit 51 or the audio output module 52.

The input unit 60 may generate key input data to control various operations of the mobile terminal according to a command input by a user. The input unit 60 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 50 in the form of a layer, a touch screen may be formed.

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 in the wireless communication unit 40 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 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-described mobile terminal hardware structure and communication system, various embodiments of the present invention are proposed.

Firstly, the present invention provides a device 400 for preventing screen misoperation, wherein the device 400 for preventing screen misoperation is suitable for the mobile terminal shown in fig. 1 to 2, and the mobile terminal is a full-screen fingerprint identification mobile terminal.

In this embodiment, the apparatus 400 for preventing screen misoperation may be divided into one or more modules, and the one or more modules are stored in the memory 20 and executed by one or more controllers (in this embodiment, the controller 30) to complete the present invention. For example, in fig. 3, the apparatus 400 for preventing screen malfunction may be divided into an information acquisition module 401, an interface name acquisition module 402, a judgment module 403, and a processing module 404. The module referred to herein is a series of computer program instruction segments capable of performing a specific function, and is more suitable than a program for describing the screen malfunction prevention process of the apparatus 400 for preventing screen malfunction. The detailed description of the functions of the

functional modules

401 and 404 will be described below.

The information obtaining module 401 is configured to, when a touch event is detected, obtain fingerprint information, a touch type, and position information corresponding to the touch event.

Because the mobile terminal is the full-screen fingerprint identification mobile terminal, when the mobile terminal detects a touch event, the fingerprint information of the touch event can be acquired. In this embodiment, the fingerprint information includes fingerprint number, fingerprint direction and area of contact, when mobile terminal gathered the fingerprint image of user's input through the touch-sensitive screen, analyzed, discerned this fingerprint image, obtained its fingerprint number, fingerprint direction and area of contact that correspond. The fingerprint number is used to identify a user identity, that is, to distinguish a user to which the fingerprint belongs, and the mobile terminal numbers the fingerprints of the users, for example, the fingerprint information of the user a corresponds to the number 1 (denoted as fingerprint 1), and the fingerprint information of the user B corresponds to the number 2 (denoted as fingerprint B), please refer to fig. 7, and fig. 7 describes the fingerprint information of the user a; the fingerprint direction is used to indicate the orientation of the fingerprint, and as shown in fig. 7, the fingerprint direction of the fingerprint 1 includes a left orientation, a right orientation, an upper orientation (i.e., the direction of the fingerprint 1 in fig. 7), and a lower orientation; the contact area is used to represent the contact area between the user's finger and the touch screen when the user inputs a touch event, and referring to fig. 7 again, the contact area includes the left edge, the right edge, the upper edge and the lower edge of the fingerprint 1, where the fingerprint 1 in fig. 7 represents the complete fingerprint information of the user a, which is in the upper orientation. For the user a, when the user a touches the mobile terminal, the mobile terminal analyzes and identifies the acquired fingerprint image of the user a, and determines whether the fingerprint information corresponding to the touch event is the situation shown in fig. 7, for example, the left edge of the fingerprint 1. In addition, in the present embodiment, the touch types include a click (click), a slide (move), and a long press (long click). The position information of the touch event is used to represent a coordinate area of the touch event on the touch screen.

The interface name obtaining module 402 is configured to obtain an application interface name of a current application interface.

In this embodiment, the current application interface refers to an application interface of an application program that runs on a foreground of the mobile terminal when the touch event is detected, that is, an application interface operated by the touch event. For any application program on the mobile terminal, each application interface has a unique application interface name, and the application interface name is an Activity name. For the application programs in the android system, an Activity is usually a single screen, and controls can be displayed on the Activity, and events of the user can be monitored, processed and responded, and the activities are communicated through Intent.

The determining module 403 is configured to search, from a history record associated with the current application interface name in a history database, whether a history record matching the fingerprint information, the touch type, and the location information exists, so as to determine whether the touch event is an incorrect operation.

In order to identify whether the touch event is an incorrect operation, a history database needs to be established on the mobile terminal in advance, and the history database includes records of the touch event when the user operates correctly. Preferably, the record includes fingerprint information, touch type, location information, package name of an application operated by the touch event, application interface name, view ID, and other information corresponding to the touch event.

Specifically, the process of establishing the historical database includes: (1) when a touch event is detected, acquiring fingerprint information, touch type and position information of the touch event; (2) acquiring a view for receiving the touch event on a current application interface and a corresponding view ID; (3) when the view has no history record, generating a history record for the view, wherein the history record comprises a view ID, fingerprint information of the touch event, a touch type, position information and operation times, and when the view has the history record, updating the history record according to the touch event; (4) and (3) executing the recording process of each touch event to establish the historical database, namely repeating the steps (1) to (3) until historical records are generated for each view on each application interface of each application program, wherein the data of all the historical records form the historical database. It should be noted that the method for preventing screen misoperation of the present invention may be only applicable to some applications, for example, only applicable to a plurality of applications commonly used by a user, and at this time, in the process of establishing a history database, only touch events of the applications need to be recorded.

Referring to fig. 13, fig. 13 is a schematic diagram of an embodiment of partial data in a history database, specifically, fig. 13 is a history record related to each view on a chat interface of an application program, which is WeChat stored in the history database after multiple records, where a coordinate area 1 is a set of all coordinate points corresponding to a return key for 3 click operations, and the other coordinate areas are similar. Referring to fig. 8 to 10, the history database establishment process is described by taking WeChat as an example, where fig. 8 is a chat interface of WeChat, as shown in fig. 8, touch events of a user are generally distributed in an upper left corner (return key), an upper right corner (viewing counterpart information), a lower left corner (input switching, such as voice and text switching), a lower right corner (input menu), and a middle bottom (text input or voice input), a corresponding view is set for each distribution area in a layout file of the chat interface, each view has a corresponding number (i.e., ID), as shown in fig. 13, the ID of the view of return key is marked as 1, the ID of the view of viewing counterpart information is marked as 2, and so on. When the touch events that the user has input on the chat interface are as shown in fig. 9 to 11, the related data recorded in the history database at this time is as shown in fig. 13, where fig. 9 is a schematic diagram showing the touch events, fig. 10 is a schematic diagram showing the touch types of the touch events in fig. 9, fig. 11 is a schematic diagram showing the coordinate areas of the touch events in fig. 9, and each oval area in fig. 11 is a schematic diagram showing a set formed by position information of a plurality of touch events therein. Referring again to fig. 12, when the touch event input by the user at the lower left corner is the fingerprint 5, the touch event is considered as a false touch because the touch event is not a regular touch event of the user, and the touch event is masked. It should be noted that, when the historical database is established, the mobile terminal may further perform cluster analysis on all recorded data, remove noise point information, calculate the size of the coordinate area of each view, count information with the maximum probability of occurrence of fingerprints and touch events in the coordinate area, and find out the general use habits of the user. In addition, the touch event of non-fingerprint touch is not recorded, and when the touch event is input, if the application interface is not changed, the touch event is regarded as an invalid operation, and is not recorded, such as for the embodiments shown in fig. 9 to 12, a long press operation in a chat area is an invalid operation, and is not recorded.

The processing module 404 is configured to respond to or shield the touch event according to the determination result. Specifically, when the touch event is an misoperation, the touch event is shielded, that is, the touch event is not responded; and responding to the touch event when the touch event is normal operation.

Through the modules 401 to 404, when a touch event is detected, the device for preventing screen misoperation firstly acquires fingerprint information, touch type and position information corresponding to the touch event, then acquires an application interface name of a current application interface, then searches whether a history record matched with the fingerprint information, the touch type and the position information exists in a history record associated with the current application interface name in a history database to judge whether the touch event is misoperation, namely, carries out multi-dimensional information acquisition on the touch event on the screen, then compares the acquired information with the history data of the touch event of a user to judge whether the current touch event is one-time normal operation or one-time mistaken touch behavior of the user, finally shields the touch event when the touch event is the mistaken operation, and greatly reduces the probability of mistaken touch occurrence of the user in the process of using the mobile terminal, the use efficiency and the user experience of the mobile terminal are improved.

Based on the first embodiment described above, a second embodiment of the device 400 for preventing screen misoperation according to the present invention is proposed.

Specifically, the process of acquiring the view on the current application interface for receiving the touch event and the corresponding view ID specifically includes: obtaining a layout file of the current application interface according to the application interface name; and searching the view receiving the touch event and the corresponding view ID from the layout file.

The auxiliary determining module 406 is configured to, when no view corresponding to the touch event exists in the layout file, search auxiliary information corresponding to the touch event from auxiliary information of an application program, where the auxiliary information includes a touch area that does not exist in the layout file on the current application interface, an attribute of the touch area, and a corresponding touch type. In this embodiment, the auxiliary information is used to perform auxiliary analysis on the current application interface, so as to determine whether a touch event is an error operation, where the touch event includes a touch area that does not exist in the layout file on the current application interface, an attribute of the touch area, and a corresponding touch type. Taking the application program of the WeChat as an example, the main interface of the WeChat belongs to the type of switching the interface by sliding left and right, and the auxiliary information of the main interface includes: and the touch area on the main interface and the attribute of the touch area are viewport + fragment, and the touch type is sliding operation. And when the touch event cannot be matched in the layout file, further judging whether the touch event is misoperation or not through auxiliary information, taking the touch event on the WeChat main interface as an example, when the touch event belongs to the sliding operation in the touch area, judging that the touch event is normal operation, otherwise, judging that the touch event is misoperation. For another example: and in the video application, when the screen is horizontally displayed, the auxiliary information added to the bottom is the control information of the playing key and the progress bar.

Through the modules 401 to 406, the device for preventing screen misoperation according to the present invention analyzes and determines the touch event through the auxiliary information when the view corresponding to the touch event cannot be found from the layout file, so that the capability of determining whether the touch event is a misoperation is improved, and the accuracy is better.

Further, the present invention provides a method for preventing screen misoperation, which is applied to the mobile terminal shown in fig. 1 to 2, wherein the mobile terminal is a full screen fingerprint identification mobile terminal.
