A mobile terminal 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.

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 devices. In particular, the broadcast receiving module 111 may receive digital broadcasting by using a digital broadcasting device such as a digital broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), data broadcasting device of forward link media (MediaFLO @), terrestrial digital broadcasting integrated service (ISDB-T), and the like. The broadcast receiving module 111 may be constructed as various broadcasting devices suitable for providing broadcast signals as well as the above-described digital broadcasting device. 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.

A typical example of the location information module is a GPS (global positioning device). According to the current technology, the location information 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 position information module 115 can calculate the speed information by continuously calculating the 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 jerky 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, 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 microphone, a buzzer, and the like.

The memory 160 may store software programs or 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, etc.) that has been output or is to 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 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 now, the mobile terminal has been described in terms of its functions. 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.

It should be noted that the mobile terminal shown in fig. 1 may also be configured to adjust the size of the screen area based on the movement of two touch points on the sensor, and specific virtual function modules included in the mobile terminal are as follows:

the first adjusting module 400 is configured to, in the split-screen display interface, adjust, when two touch points acting on the sensor are detected, positions of corresponding middle boundary lines of the two touch points on the display screen along with movement of the two touch points on the sensor;

the second adjusting module 500 is configured to fix the split screen boundary line to a position where the two touch points leave the middle boundary line corresponding to the moment before, and correspondingly adjust the size of the split screen area when the two touch points leave the sensor.

In the mobile terminal shown in fig. 1, the user input unit 130 is provided with a sensor, and in the split screen display interface, when a user wants to adjust the size of the current split screen area, the user can touch the sensor with two fingers, so that when the first adjusting module 400 detects two touch points acting on the sensor, the positions of the middle boundary lines corresponding to the two touch points on the display screen are adjusted along with the movement of the two touch points on the sensor, and when the two touch points leave the sensor, the second adjusting module 500 fixes the split screen boundary lines to the positions where the two touch points leave the middle boundary line corresponding to the previous moment, and correspondingly adjusts the size of the split screen area, thereby achieving a simple and rapid adjustment of the size of the split screen area.

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 devices.

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 an apparatus as shown in fig. 2 may include a plurality of BSCs 275.

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 sub-assembly (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 apparatus. 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 device (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 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-mentioned mobile terminal hardware structure and communication system structure, various embodiments of the apparatus and method of the present invention are proposed.

The present invention further provides a device for adjusting the size of a split screen area, as shown in fig. 3, which shows a schematic diagram of a functional module according to a first embodiment of the device for adjusting the size of a split screen area of the present invention, wherein the device for adjusting the size of a split screen area comprises:

the acquiring unit 410 is configured to acquire a first pressure value and a second pressure value corresponding to two touch points acting on the pressure sensor when the two touch points are detected on the split-screen display interface;

the determining unit 420 is configured to determine whether the obtained first pressure value and the obtained second pressure value meet a preset split-screen adjustment condition;

and an adjusting unit 430, configured to adjust positions of the corresponding middle boundary lines of the two touch points on the display screen along with movement of the two touch points on the pressure sensor when the first pressure value and the second pressure value satisfy the split-screen adjustment condition.

In the split-screen display interface, assuming that split-screen contents of two applications are already displayed on a display screen of the mobile terminal (as shown in fig. 5, a split-screen boundary is provided at a junction of the split-screen contents of the two applications), taking finger pressing as an example, when a user presses an area provided with a pressure sensor with two fingers, the obtaining unit 410 of the first adjusting module 400 may detect two touch points acting on the pressure sensor through the pressure sensor, and may calculate pressure values corresponding to the two touch points, that is, a first pressure value and a second pressure value.

After the obtaining unit 410 of the first adjusting module 400 of the mobile terminal obtains the first pressure value and the second pressure value, the determining unit 420 determines whether the first pressure value and the second pressure value satisfy the preset split-screen adjusting condition, when the first pressure value and the second pressure value satisfy the split-screen adjusting condition, the mobile terminal enters a state of adjusting the size of the split-screen area, otherwise, the mobile terminal remains the original state. The split screen adjustment condition comprises a preset pressure threshold value, and the pressure threshold value can be reasonably set according to the pressure value when a large number of users press the pressure sensor.

Further, the judging unit 420 includes:

the first determining subunit is used for determining that the first pressure value and the second pressure value meet the split-screen adjustment condition when the first pressure value and the second pressure value are both greater than or equal to a preset pressure threshold value; or,

and the second determining subunit is used for determining that the first pressure value and the second pressure value meet the split-screen adjustment condition when a third pressure value obtained by calculation according to the first pressure value and the second pressure value is greater than or equal to a pressure threshold value.

The embodiment provides two ways for judging whether the acquired first pressure value and the acquired second pressure value meet the split-screen adjustment condition, the first way is that when two pressure values of two fingers of a user pressing the pressure sensor are both larger than or equal to a set pressure threshold value, the first determining subunit determines that the first pressure value and the second pressure value meet the split-screen adjustment condition, at this moment, the mobile terminal enters a split-screen area size adjustment state, the way limits the sizes of the pressure values of two touch points, and the situation that the mobile terminal enters the split-screen area size adjustment state due to mistaken touch operation can be avoided; the second mode is that the second determining subunit obtains a third pressure value by calculating an average value or calculating a sum of two pressure values obtained when the two fingers of the user press the pressure sensor, and then compares the third pressure value with a correspondingly set pressure threshold value, and determines that the first pressure value and the second pressure value satisfy the split-screen adjustment condition when the third pressure value is greater than or equal to the pressure threshold value, at this time, the mobile terminal enters a state of adjusting the size of the split-screen area, and the mode relieves the size limitation of the respective pressure values of the two touch points while emphasizing on the size limitation of a comprehensive pressure value obtained by calculation based on the two pressure values, so that the user can easily trigger the mobile terminal to enter the state of adjusting the size of the split-screen area by using the two fingers.

Further, referring to fig. 6, the adjusting unit 430 includes:

a mapping subunit 431, configured to map the two touch points onto the display screen in real time based on current positions of the two touch points on the pressure sensor;

at each time when the two touch points move on the pressure sensor, the mapping subunit 431 of the mobile terminal can acquire the current positions of the two touch points on the pressure sensor through the pressure sensor, and can map the relative positions of the two touch points on the sensor to the corresponding positions on the display screen based on the size of the display screen of the mobile terminal, so as to obtain two mapping points of the two touch points on the display screen.

A drawing subunit 432, configured to determine a midpoint of mapping points of the two touch points on the display screen, and draw a dotted line passing through the midpoint and parallel to a current screen dividing line on the display screen as a corresponding middle dividing line of the two touch points on the display screen;

and a deletion subunit 433, configured to delete, when the positions of the two touch points are changed, the middle boundary line corresponding to the position before the change.

After determining two mapping points of the current two touch points on the display screen, the drawing subunit 432 may determine a middle point based on the two mapping points, for example, a middle point of a connecting line of the two mapping points, and draw a dotted line parallel to the current split screen dividing line on the display screen through the middle point, so as to use the drawn dotted line as the corresponding middle dividing line of the two touch points on the display screen. The current split screen boundary is located at an initial position before the split screen area is adjusted, that is, the split screen boundary shown in fig. 5 is located, and in the process of moving the two touch points, the sizes of the split screen areas of the two applications are kept unchanged, and the split screen contents of the two applications are also kept unchanged, so that the phenomenon that the mobile terminal is stuck and even crashes due to real-time and large-scale drawing (that is, real-time updating of the split screen contents) can be avoided.

Therefore, in the process that the two touch points move on the pressure sensor, the adjusting unit 430 adjusts the positions of the middle boundary lines corresponding to the two touch points in real time according to the changes of the positions of the two touch points, and when the positions of the two touch points change, the deleting subunit 433 of the mobile terminal deletes the middle boundary line corresponding to the position before the change, so that only one middle boundary line is displayed on the display screen, and the middle boundary line moves correspondingly along with the movement of the finger of the user from the perspective of the user. If the pressure sensor is arranged on the display screen, the middle boundary line is always positioned at the middle position where two fingers of the user press the display screen from the user perspective, and corresponding movement is carried out along with the movement of the two fingers.

When the pressure value of at least one of the two touch points detected by the mobile terminal is 0, the second adjustment module 500 considers that the two touch points leave the pressure sensor, and at this time, the second adjustment module 500 of the mobile terminal moves the split screen boundary line to the position of the middle boundary line corresponding to the previous moment when the two touch points leave the pressure sensor, and does not change the position of the split screen boundary line at this time, and performs corresponding adjustment on the size of the split screen area based on the position of the split screen boundary line at this time, thereby completing the adjustment on the size of the split screen area.

The split screen area size adjusting device provided by the invention adjusts the positions of the corresponding middle boundary lines of the two touch points on the display screen on the basis of the movement of the two touch points acting on the sensor on the split screen display interface, and when the two touch points are detected to leave the sensor, the split screen boundary lines are fixed to the positions where the two touch points leave the middle boundary lines corresponding to the previous moment, and the split screen area size is adjusted correspondingly, so that the split screen area size adjusting device is simple in adjustment operation, simple, rapid and convenient in adjustment of the split screen area size is realized, and the false touch operation can be avoided.

Further, a second embodiment of the split screen area size adjusting apparatus according to the present invention is provided based on the first embodiment of the split screen area size adjusting apparatus, and the difference is that in this embodiment, a split screen boundary moves correspondingly with the movement of two touch points, that is, referring to fig. 7, the split screen area size adjusting apparatus further includes a third adjusting module 600, and the third adjusting module 600 is configured to:

and controlling the split screen boundary to move based on the position of the drawn middle boundary line in the process that the two touch points move on the sensor, and correspondingly updating the content of each split screen along with the movement of the split screen boundary line.

In the third adjustment module 600, during the process of moving two touch points on the pressure sensor, the position of the split-screen boundary line is the same as the position of the middle boundary line drawn in real time, that is, the split-screen boundary line moves the same as the middle boundary line moves on the display screen. In the moving process of the split screen boundary, the third adjusting module 600 of the mobile terminal correspondingly adjusts the size of the split screen area based on the real-time position of the split screen boundary, and correspondingly updates the split screen content of the application in different split screen areas, so that the user can check the dynamic effect of the size adjustment of the split screen area in real time along with the movement of the two touch points, as shown in fig. 8.

According to the split screen area size adjusting device provided by the invention, the split screen boundary moves based on the position of the drawn middle boundary line along with the movement of the two touch points, and the split screen content is dynamically updated according to the size of the split screen area based on the movement of the split screen boundary line, so that a user can check the dynamic effect of the split screen area size adjustment in real time, and the adjustment effect is visual.

Further, a third embodiment of the split-screen area size adjusting apparatus according to the present invention is proposed based on the second embodiment of the split-screen area size adjusting apparatus, and the difference is that in the present embodiment, in the process that the split-screen dividing line moves based on the position of the drawn middle boundary line, each split-screen content is replaced with an application icon of a corresponding application with a smaller drawing amount, that is, the third adjusting module 600 is configured to:

in the process of moving the two touch points on the sensor, the control split-screen boundary line moves based on the position of the drawn middle boundary line, and each split-screen content is replaced by an application icon of the corresponding application, and each application icon scales with the size of the corresponding split-screen area.

Because the split screen content of each application in the split screen area is correspondingly updated in real time in the process that the split screen boundary moves based on the position of the drawn middle boundary line, the split screen display method has larger drawing workload for the mobile terminal and has higher requirements on hardware support of the mobile terminal. In order to avoid the occurrence of a mobile terminal jamming or even a dead halt phenomenon caused by a large drawing workload and to bring a dynamic visual effect of adjusting the size of the split screen area to the user, the third adjusting module 600 may replace each split screen content with an application icon of a corresponding application, and each application icon may be correspondingly enlarged or reduced along with the size of the corresponding split screen area, as shown in fig. 9.

According to the split-screen area size adjusting device provided by the invention, in the process that the split-screen boundary moves based on the position of the drawn middle boundary line, each split-screen content is replaced by the corresponding application icon, and each application icon is correspondingly enlarged or reduced along with the size change of the corresponding split-screen area, so that the drawing workload when the split-screen content is updated is greatly reduced, and the stable performance of the mobile terminal is ensured.

The invention further provides a first embodiment of a split screen area size adjusting method, which corresponds to the first embodiment of the split screen area size adjusting device. As shown in fig. 10, a flowchart illustrating a first embodiment of the method for adjusting the size of the split screen area according to the present invention is shown, where the method for adjusting the size of the split screen area includes:

s10, on the split-screen display interface, when two touch points acting on the sensor are detected, along with the movement of the two touch points on the sensor, the positions of the corresponding middle boundary lines of the two touch points on the display screen are adjusted;

the method for adjusting the size of the split screen area can be implemented on the mobile terminal, the mobile terminal is provided with a sensor, and the sensor can be arranged on a display screen of the mobile terminal, a side frame of the mobile terminal, or the back of the mobile terminal, or an existing function key. The sensor arranged on the mobile terminal can be a pressure sensor, a capacitive touch sensor on a touch screen and the like.

The two touch points detected by the mobile terminal can be two touch points detected by the sensor when two fingers of a user touch the area where the sensor is located; it can also be two touch points detected by the sensor when the user touches the area of the sensor with two touch pens, and so on.

Taking a pressure sensor as an example, referring to fig. 11, step S10 includes:

s11, on the split-screen display interface, when two touch points acting on the pressure sensor are detected, acquiring a first pressure value and a second pressure value corresponding to the two touch points, and judging whether the acquired first pressure value and the acquired second pressure value meet preset split-screen adjustment conditions or not;

and S12, when the first pressure value and the second pressure value meet the split screen adjustment condition, adjusting the positions of the corresponding middle boundary lines of the two touch points on the display screen along with the movement of the two touch points on the pressure sensor.

In the split-screen display interface, assuming that split-screen contents of two applications are already displayed on a display screen of the mobile terminal (as shown in fig. 5, a split-screen boundary is arranged at a junction of the split-screen contents of the two applications), taking finger pressing as an example, when a user presses an area provided with a pressure sensor with two fingers, the pressure sensor can detect two touch points acting on the area, and can calculate pressure values corresponding to the two touch points, that is, a first pressure value and a second pressure value.

After the mobile terminal acquires the first pressure value and the second pressure value, whether the first pressure value and the second pressure value meet preset split screen adjustment conditions or not is judged, when the first pressure value and the second pressure value meet the split screen adjustment conditions, the mobile terminal enters a split screen area size adjustment state, and otherwise, the mobile terminal keeps an original state unchanged. The split screen adjustment condition comprises a preset pressure threshold value, and the pressure threshold value can be reasonably set according to the pressure value when a large number of users press the pressure sensor.

Further, judging whether the acquired first pressure value and the acquired second pressure value meet preset split-screen adjustment conditions includes:

The embodiment provides two ways for judging whether the acquired first pressure value and the acquired second pressure value meet the split-screen adjustment condition, the first way is that when two pressure values of two fingers of a user pressing the pressure sensor are both larger than or equal to a set pressure threshold value, the first pressure value and the second pressure value are determined to meet the split-screen adjustment condition, at the moment, the mobile terminal enters a split-screen area size adjustment state, the way limits the sizes of the pressure values of two touch points, and the condition that the mobile terminal enters the split-screen area size adjustment state due to mistaken touch operation can be avoided; the second method is that according to two pressure values obtained when two fingers of a user press the pressure sensor, a third pressure value is obtained by calculating an average value or calculating a sum of the two pressure values, the third pressure value is compared with a correspondingly set pressure threshold value, when the third pressure value is larger than or equal to the pressure threshold value, the first pressure value and the second pressure value are determined to meet a split screen adjustment condition, at the moment, the mobile terminal enters a split screen area size adjustment state, size limitation of respective pressure values of the two touch points is relieved by the method, and size limitation of a comprehensive pressure value calculated based on the two pressure values is emphasized, so that the user can easily trigger the mobile terminal to enter the split screen area size adjustment state by using the two fingers.

Further, referring to fig. 12, the step S12 includes:

s121, mapping the two touch points to a display screen in real time based on the current positions of the two touch points on the pressure sensor;

at each moment when the two touch points move on the pressure sensor, the mobile terminal can acquire the current positions of the two touch points on the pressure sensor through the pressure sensor, and can map the relative positions of the two touch points on the sensor to the corresponding positions on the display screen based on the size of the display screen of the mobile terminal, so as to obtain two mapping points of the two touch points on the display screen.

S122, determining the middle point of the mapping points of the two touch points on the display screen, and drawing a dotted line which passes through the middle point and is parallel to the current split screen boundary line on the display screen as the corresponding middle boundary line of the two touch points on the display screen;

after determining two mapping points of the current two touch points on the display screen, a middle point, for example, a middle point of a connecting line of the two mapping points, can be determined based on the two mapping points, and then an imaginary line parallel to the current split screen dividing line on the display screen is drawn through the middle point, so that the drawn imaginary line is taken as a corresponding middle dividing line of the two touch points on the display screen. The current split screen boundary is located at an initial position before the split screen area is adjusted, that is, the split screen boundary shown in fig. 5 is located, and in the process of moving the two touch points, the sizes of the split screen areas of the two applications are kept unchanged, and the split screen contents of the two applications are also kept unchanged, so that the phenomenon that the mobile terminal is stuck and even crashes due to real-time and large-scale drawing (that is, real-time updating of the split screen contents) can be avoided.

Therefore, in the process that the two touch points move on the pressure sensor, the positions of the middle boundary lines corresponding to the two touch points are adjusted in real time according to the changes of the positions of the two touch points, and when the positions of the two touch points change, the mobile terminal deletes the middle boundary line corresponding to the position before the change, so that only one middle boundary line is displayed on the display screen, and the middle boundary line moves correspondingly along with the movement of the finger of the user from the perspective of the user. If the pressure sensor is arranged on the display screen, the middle boundary line is always positioned at the middle position where two fingers of the user press the display screen from the user perspective, and corresponding movement is carried out along with the movement of the two fingers.

And S20, when the two touch points leave the pressure sensor, fixing the split screen boundary line to the position where the two touch points leave the middle boundary line corresponding to the previous moment, and correspondingly adjusting the size of the split screen area.

When the pressure value of at least one touch point in the two pressure values detected by the mobile terminal is 0, the two touch points are considered to leave the pressure sensor, at this time, the mobile terminal moves the split screen boundary to the position of the middle boundary line corresponding to the moment when the two touch points leave the pressure sensor, the position of the split screen boundary line at this moment is not changed any more, and the size of the split screen area is correspondingly adjusted based on the position of the split screen boundary line at this moment, so that the adjustment of the size of the split screen area is completed.

The method for adjusting the size of the split screen area provided by the invention adjusts the position of the corresponding middle boundary line of the two touch points on the display screen on the basis of the movement of the two touch points acting on the sensor on the split screen display interface, and when the two touch points are detected to leave the sensor, the split screen boundary line is fixed to the position where the two touch points leave the middle boundary line corresponding to the previous moment, and the size of the split screen area is adjusted correspondingly, so that the adjustment operation is simple, the simple and rapid adjustment of the size of the split screen area is realized, and the false touch operation can be avoided.

Further, a second embodiment of the split screen area size adjusting method according to the present invention is provided based on the first embodiment of the split screen area size adjusting method, which corresponds to the second embodiment of the split screen area size adjusting device described above, and is different in that in this embodiment, a split screen boundary moves correspondingly with the movement of two touch points, that is, the split screen area size adjusting method further includes:

In this embodiment, in the process of moving the two touch points on the pressure sensor, the position of the dividing line of the split screen is the same as the position of the middle boundary line drawn in real time, that is, the dividing line of the split screen moves the same as the middle boundary line moves on the display screen. In the moving process of the split screen dividing line, the mobile terminal correspondingly adjusts the size of the split screen area based on the position of the real-time split screen dividing line, and correspondingly updates the split screen content of the application in different split screen areas, so that a user can check the dynamic effect of the size adjustment of the split screen area in real time along with the movement of the two touch points, as shown in fig. 8.

According to the method for adjusting the size of the split screen area, the split screen boundary moves along with the movement of the two touch points and based on the position of the drawn middle boundary, and the split screen content is dynamically updated according to the size of the split screen area based on the movement of the split screen boundary, so that a user can check the dynamic effect of adjusting the size of the split screen area in real time, and the adjustment effect is visual.

Further, a third embodiment of the split-screen area size adjusting method according to the present invention is provided based on the second embodiment of the split-screen area size adjusting method, which corresponds to the third embodiment of the split-screen area size adjusting device described above, and is different from the first embodiment in that, in a process in which a split-screen boundary moves based on a position of a drawn middle boundary, each split-screen content is replaced with an application icon of a corresponding application having a smaller drawing amount, that is, the split-screen area size adjusting method further includes:

Because the split screen content of each application in the split screen area is correspondingly updated in real time in the process that the split screen boundary moves based on the position of the drawn middle boundary line, the split screen display method has larger drawing workload for the mobile terminal and has higher requirements on hardware support of the mobile terminal. In order to avoid the occurrence of a mobile terminal jamming or even a dead halt phenomenon caused by a large drawing workload and to bring a dynamic visual effect of adjusting the size of the split screen area to the user, each split screen content may be replaced with an application icon of a corresponding application, and each application icon may be correspondingly enlarged or reduced along with the change of the size of the corresponding split screen area, as shown in fig. 9.

According to the method for adjusting the size of the split screen area, each split screen content is replaced by the corresponding application icon in the process that the split screen boundary moves based on the position of the drawn middle boundary line, and each application icon is correspondingly enlarged or reduced along with the size change of the corresponding split screen area, so that the drawing workload when the split screen content is updated is greatly reduced, and the stable performance of the mobile terminal is ensured.
