Referring to fig. 1, fig. 1 shows a flowchart of a screen control method according to an embodiment of the present disclosure, and the embodiment of the present disclosure provides a method for screen control, where the method is at least applied to a situation that a mobile terminal starts an earpiece device in a call state, and when a touch point of the mobile terminal reaches a threshold preset by the mobile terminal, a touch screen of a mobile phone is turned off, so as to prevent a user from mistakenly touching the touch screen when the mobile terminal is in a call.
As shown in fig. 1, in an embodiment of the present application, a screen control method includes:
step S210, monitoring and obtaining that the mobile terminals are in a call state, wherein the call state means that the mobile terminals in communication are all in a call state;
step S220, for the mobile terminal in the conversation state, the occurrence of a receiver event is obtained through the operation monitoring of the audio management service;
step S230, in response to the occurrence of the earphone event, monitoring the multi-touch triggered by the screen to obtain the number of touch points;
and S240, triggering the screen to automatically extinguish according to the number of the touch points, wherein the automatically extinguished screen keeps being extinguished in the call state.
These 4 steps are described in detail below.
In step S210, in this embodiment, the screen is controlled to implement the function of preventing the mobile terminal from being touched by mistake in the call state, so as to avoid any misoperation in the call state. In the process, monitoring of the call state of the mobile terminal is firstly realized, and whether the mobile terminal enters the call state is monitored in real time.
The call state is a state into which the call of the mobile terminal is switched after being answered, and on one hand, for the mobile terminal initiating the call, the initiated call is answered, and on the other hand, for the mobile terminal called by the call in the mobile communication, the communication state is answered in response to ringing. It should be noted that the initiated call may exist between two mobile terminals or between a plurality of mobile terminals. For the initiated call, more than two mobile terminals enter the call state, and through the application, the realization of preventing mistaken touch on any mobile terminal entering the communication state is ensured.
Therefore, for the call state, in the execution of step S210, it can be determined whether the mobile terminal enters the call state according to whether the mobile terminal is triggered to perform an answering action, and once the answering action is triggered, it is determined that the mobile terminal enters the call state, where the answering action is used to connect a call in response to the initiated ringing for the call initiated between the mobile terminals.
The method can be used for initiating the false touch prevention implementation process of the application as long as the mobile terminal enters a call state no matter the initiated call is between two mobile terminals or between a plurality of mobile terminals, and no matter whether other mobile terminals respond to ringing to enter a communication state, so that the mobile terminal which enters the call state can not be influenced to implement the false touch prevention function even if the mobile terminal which does not respond to answering exists in the multi-person call.
In the mobile terminal, once the mobile terminal is monitored to be in a call state, the use of the mobile terminal by a user is monitored based on the method, so that whether misoperation needs to be prevented or not in the call process is accurately identified and controlled, the holding posture of the user on the mobile terminal in the call state is adaptively adapted, and the continuous call process is comprehensively protected.
Referring to fig. 2, fig. 2 is a flowchart illustrating a process of obtaining a call state of a mobile terminal by monitoring according to an embodiment of the present application. The embodiment of the present application provides step S210 of obtaining that the mobile terminal is in a call state by monitoring, including:
step S211, responding to the running of the voice call application in the mobile terminal, triggering and monitoring whether the voice call application jumps to enter a voice activation state;
step S212, if the voice call application skips to enter the voice activation state, it is determined that the mobile terminal is in the call state.
These two steps are described in detail below.
In step S211, it is to be understood that the voice call application on the mobile terminal can enter a voice call through the internet, and the voice call application refers to an application having a function of implementing a call through the internet. In addition, the application capable of entering the call state on the mobile terminal further comprises: and the application of realizing the call by utilizing the mobile network to carry out mobile communication. Therefore, the voice call application is various social network applications, and the call between the mobile terminals is realized by initiating the voice call through the social network application on the internet.
When the voice call application of the mobile terminal runs, the monitoring of whether the voice call application jumps into a voice activation state is initiated, so that the monitoring of whether the mobile terminal is in a call state is realized. The voice activated state means that an application having a call function using the internet is implementing the call function and is in a connected state.
In step S212, during the operation of the voice call application of the mobile terminal, the activated voice call of the voice call application operated by the mobile terminal is accurately captured along with the monitoring of whether to jump into the voice activated state, so that the mobile terminal must enter the call state along with the activation of the voice call.
It can be understood that the occurrence of the call on the mobile terminal is accurately captured by monitoring the running process of the voice call application, so that the call on the mobile terminal can be self-adaptively and accurately realized to prevent the false touch function when needed.
In step S220, it should be noted that the mobile terminal in the call state is often held by the user, and the mobile terminal approaches or contacts the auricle or even the face of the user when the user holds the mobile terminal, so as to achieve the call through the earphone. Based on this, for the mobile terminal entering the call state, it is required to monitor whether the earpiece device is enabled through the execution of step S220.
In particular, whether the earpiece device is enabled is a process of listening for earpiece events through the execution of the audio management service. The audio management service is used for changing the audio input and output states of the mobile terminal, for example, the audio management service is used for realizing the adjustment of volume and changing a port inputting and outputting audio; the earphone event refers to an event that the mobile terminal in a call switches the earphone device into the current call audio output device.
The mobile terminal monitors the operation of the audio management service, identifies the audio output equipment using the audio port of the mobile terminal in the call state, and judges that the mobile terminal is using the earphone equipment in the call state when the earphone equipment is used as the audio output equipment outputting call audio.
The application scene based on the mobile terminal conversation state is to avoid the false touch event of contact between an auricle (especially with edge characteristics) or a cheek and a mobile terminal screen under a holding scene when the mobile terminal and the face side have a larger included angle when the mobile terminal is in the conversation state, so as to avoid the condition of disconnection of the conversation or other influences on the communication experience. The above-described situation of call interruption occurs only when a call is made using an earpiece device. When the speaker device or the external audio output device is used, for example, the external audio output device such as an earphone or a sound device does not have the above false touch scene, or the probability of false touch is extremely low, and the operation experience of the user, such as gesture operation, can be influenced on the contrary by starting the false touch prevention function at this time. Therefore, the false touch prevention function is performed when the mobile terminal is in a call state and the earphone device is used as the audio output device of the audio port, and at the moment, the false touch prevention function is necessary to be started.
Referring to fig. 3, fig. 3 is a flowchart illustrating enabling of a handset event through operation monitoring of an audio management service for a mobile terminal in a call state according to an embodiment of the present application. The embodiment of the present application provides step S220 of obtaining the enabling of the earphone event through the operation monitoring of the audio management service for the mobile terminal in the call state, including:
step S221, monitoring whether an audio port of the mobile terminal triggers an update event through an audio management service, wherein the update event is used for controlling the state change of audio output equipment which outputs audio;
step S222, when the audio port is triggered to update the event, searching for audio output equipment of the audio port;
step S223, obtaining an audio output device list according to the identifier of the audio output device, wherein the audio output device list is used for dynamically recording the audio output device currently in the output state of the mobile terminal;
step S224, monitoring whether the identifier of the earphone device exists in the audio output device list, and if so, determining that an earphone event is triggered when the mobile terminal is in a call state.
These 4 steps are described in detail below.
In step S221, when the mobile terminal is in a call state, the audio management service monitors whether an audio port of the mobile terminal triggers an update event, where the update event is a change in the state of an audio output device of the audio port of the mobile terminal. If the audio output device A is changed from the output state to the closed state; the audio information output by the audio output equipment A is changed to be output by the audio output equipment B; the output source of the audio information changes, the application X outputs the audio information through the audio output device A, and the change is that the application Y outputs the audio information through the audio output device A.
When the mobile terminal in the call state changes the call audio output device in response to the operation of the user, or the mobile terminal enters the call state, the source of the audio information output by the audio output device changes, or the output device of the audio information changes, which causes the update event of the audio port to be triggered.
In step S222, when the update event of the audio port occurs, the mobile terminal searches for the audio output device of the audio port currently in the output state, so as to obtain the usage of each audio port in the call state, and obtains an identifier of the audio output device used for call audio output in the corresponding call state, where the identifier is used for uniquely identifying the audio output device and distinguishing other audio output devices except the audio output device itself.
In step S223, a device list including all the identifiers of the audio output devices outputting audio is formed from the obtained identifiers of the audio output devices currently outputting audio, and the device list repeats the step of obtaining the list with each occurrence of an audio output device update event, so as to obtain a new device list. The device list is composed of audio output device identifications that are outputting audio.
In step S224, the device list is obtained, whether the identifier corresponding to the handset device of the mobile terminal exists is monitored, and if yes, it is directly determined that the mobile terminal is in a call state, and the handset device is used as a device for outputting call audio of the mobile terminal.
For a common situation at present, that is, the capacitance value change is detected only by the screen capacitance sensor to identify the approach event, so as to realize the realization of the function of preventing the false touch in the communication state of the mobile terminal, but the scheme can not completely replace the effect of the approach sensor, and can not give consideration to some holding posture habits of users. For example, when some users talk, the front of the mobile phone is close to (or attached to) the cheek and the ear, but usually forms an angle with the latter. In this case, since the physical contact area is greatly reduced, the capacitance sensor cannot conveniently detect the change of the capacitance value. The approach behavior cannot be reliably identified by simply detecting the capacitance change. According to the method and the device, on the basis that the mobile terminal is provided with the capacitance sensor, the multipoint touch function of the mobile terminal is utilized in multiple aspects, the stable touch condition of the screen of the mobile terminal is obtained, and therefore the problem that the capacitance sensor cannot conveniently detect the change of the capacitance value is well solved.
In step S230, when the mobile terminal is in a call state and the port outputting the call audio is the port corresponding to the earphone device, the multi-touch on the screen is detected to obtain the number of touch points, and when the number of touch points reaches the preset value of the mobile terminal, the mobile terminal turns on the mis-touch prevention function of the mobile terminal in a screen-off manner.
The screen of the mobile terminal has a touch function, and the touch function is realized by receiving capacitance change from the screen through a matched capacitance sensor. According to the method and the device, the number of the touch points is acquired by utilizing the existing functions of the capacitive sensor and the multi-point touch of the mobile terminal, and then whether the mobile terminal needs to start the mistaken touch prevention function or not is judged according to the number of the touch points.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for monitoring a number of touch points obtained by multi-touch on a screen in response to enabling of an earpiece event according to an embodiment of the present application. The embodiment of the present application provides step S230, in which the mobile terminal is configured to use the screen as a test, and in response to enabling of the earpiece event, the multi-touch occurring on the screen is monitored to obtain the number of touch points, where the step includes:
step S231, determining the number of areas of the capacitive change on the capacitive sensor, which are mapped on the screen, and acquiring the capacitance value variation of each area;
in step S232, the number of touch points is obtained according to the number of the regions and the capacitance variation of each region.
These 2 steps are described in detail below.
In step S231, the present application is applied to a mobile terminal having a multi-touch screen, where the multi-touch function is implemented based on the capacitance change of the capacitive sensor, and the position, number and magnitude of the capacitance change area. When the bioelectric field is close to and touches the upper part of the screen of the mobile terminal, the capacitance of the touch or close area is changed. The multi-point touch function is used for responding to capacitance change of one or more areas caused by the biological electric field, acquiring the position and the number of the capacitance change areas and capacitance value change quantity of each area, comparing the capacitance value change quantity of the capacitance change areas with a set upper limit of the mobile terminal, and if the capacitance value change quantity of the capacitance change areas is smaller than the upper limit, determining the areas as touch points; if the touch area is larger than the upper limit, the area is determined to be a touch surface, the number of touch points is determined by the method, and the change of the track of the bioelectric field is responded at the same time.
The capacitive sensor is configured for the mobile terminal with the multi-point touch screen, other capacitive sensors are not needed to be additionally arranged, the multi-point touch technology is used for detecting the number of touch points, and whether the mistaken touch prevention function is started or not is determined according to the number of the touch points.
When the mobile terminal is in a call state and the audio output device used for outputting audio by call is a headphone device, the capacitance change of the capacitance sensor is acquired, and then the number of regions on the screen where capacitance changes and the capacitance change amount of each region are obtained according to the capacitance change.
In step S232, when the screen of the mobile terminal is in a contacted state, point contact and/or surface contact may occur, and therefore, it is necessary to determine whether the contacted state is surface contact according to the capacitance variation of each area, when the capacitance variation of all areas reaches the preset upper limit of the mobile terminal, it is determined that the contacted state is surface contact, and when the capacitance variation of all areas does not reach the preset upper limit of the mobile terminal, it is determined that the contacted state is point contact. And confirming the number of touch points according to two different contact states, wherein the number of the touch points is directly judged to be a touch point number threshold value during surface contact, and the number of the touch points is consistent with the number of the capacitance value change area during point contact, namely the number of the touch points is the number of the capacitance value change area.
Referring to fig. 5, fig. 5 is a flowchart illustrating a process of obtaining the number of touch points according to the number of areas and the capacitance variation of each area according to the embodiment of fig. 4. The embodiment of the present application provides step S232 of obtaining the number of touch points according to the number of areas and the capacitance variation of each area, including:
step S2321, judging whether the capacitance variation exceeds a preset upper limit of capacitance variation one by one for each region;
in step S2322, when the capacitance variation is smaller than the capacitance variation upper limit, the number of the areas is set as the number of the touch points.
These 2 steps are described in detail below.
In step S2321, the capacitance variation amount of each region is compared with a capacitance variation upper limit preset by the mobile terminal. The capacitance change upper limit is generally the largest capacitance change amount under the condition of point contact when a user touches the screen of the mobile terminal, and if the capacitance change amount of the area is less than or equal to the value, it can be determined that the capacitance change area is point contact. And determining whether the capacitance value change area is point contact or surface contact according to the steps so as to detect the number of touch points on the screen of the mobile terminal.
In step S2322, it is determined whether the capacitance change area is a point contact or a surface contact, and when the capacitance variation is smaller than the upper limit of capacitance variation, each capacitance change area is a point contact, that is, the number of touch points is consistent with the capacitance change area, that is, the number of touch points is obtained according to the number of areas where capacitance varies.
When there is an area in all the capacitance value change areas where the capacitance value change amount reaches or exceeds the upper limit of the capacitance value change, it is considered that there is a surface contact on the screen of the mobile terminal, such as a palm, a face, or a local skin contact or approach of a human body. At this time, the number of the touch points on the screen of the mobile terminal is considered as the preset touch point number threshold of the mobile terminal.
In step S240, the acquired number of touch points is compared with a preset threshold of the number of touch points of the mobile terminal, where the threshold of the number of touch points is used to control the screen to be automatically turned off in a call state, and the threshold of the number of touch points is a preset threshold for determining whether to turn on a false touch function, and when the number of touch points reaches or exceeds the threshold, the false touch prevention function of the mobile terminal is turned on, that is, the screen of the mobile terminal is turned off.
Referring to fig. 6, fig. 6 is a flowchart illustrating triggering the screen to automatically turn off according to the number of touch points according to an embodiment of the present application. Step S240 of triggering the screen to automatically turn off according to the number of touch points includes:
step S241, when the mobile terminal is in a receiver conversation state, judging whether to simulate an approach event and/or a contact event according to the number of touch points;
in step S242, when the proximity event and/or the contact event is detected, the mobile terminal performs a screen-off process to start a false touch prevention mode.
These 2 steps are described in detail below.
In step S241, a proximity event and/or a contact event is simulated according to the detected number of touch points, and when the proximity event and/or the contact event occurs, the mobile terminal activates a false touch prevention function to turn off a screen of the mobile terminal to prevent a user from touching the screen by mistake. The approach event and the contact event refer to an event that when a conductive object such as a human face approaches, an electric field of a living being carried by the living being causes a change in an electric field of the screen capacitive sensor, and a capacitance value changes. When the face is away from the screen, the electric field returns to normal level again. The approach distance is very small, or the capacitance value is directly attached to the touch screen, so that the change of the capacitance value can be generated, and the approach/departure event can be simulated according to the number of the areas with the change of the capacitance value and the change of the capacitance value of each area. And under the conversation state of the receiver, judging whether the number of the touch points exceeds a set touch point number threshold, and if so, simulating a proximity event and/or a contact event.
In step S242, when the approach event and/or the touch event is simulated, the mobile terminal determines that a false touch occurs at this time, and then performs a screen-off process to start a false touch prevention function.
The following describes a process of implementing the false touch prevention function by the mobile terminal, taking the mobile terminal in a mobile network and internet scene as an example. Monitoring whether the mobile terminal is in a call state, monitoring whether the mobile terminal in the call state uses a receiver device as a call audio output device, detecting the touch condition of the screen to obtain the number of touch points, triggering the screen to automatically extinguish according to the number of the touch points, and keeping the screen to extinguish in the screen extinguishing state.
Whether the mobile terminal is in an answering state or not is monitored in the internet or a mobile network scene, and the answering state is divided into the following two conditions: firstly, a mobile terminal applies for a call with another mobile terminal, such as a call made in life, and after another mobile terminal answers, the mobile terminal is considered to be in a call state.
Secondly, the other mobile terminals apply for talking with the mobile terminal, the mobile terminal is prompted to apply for talking with the mobile terminal, the mobile terminal agrees with the applications of the other mobile terminals according to the prompt, answers the talking with the other mobile terminals, and the mobile terminal is in a talking state at the moment. It should be understood that when the mobile terminal applies for a call with a plurality of mobile terminals, as long as one of the mobile terminals answers the call, the mobile terminal enters a call state.
When the mobile terminal is in a call state, monitoring whether an audio update event occurs at an audio port of the mobile terminal through an audio management service, wherein the update event refers to a change of the state of an audio output device at the audio port of the mobile terminal. If the audio output device A is changed from the output state to the closed state; the audio information output by the audio output device A is changed to be output by the audio output device B; the output source of the audio information changes, the application X outputs the audio information through the audio output device A, and the change is that the application Y outputs the audio information through the audio output device A.
When the update event of the audio port occurs, the mobile terminal searches the audio output devices of the audio port currently in the output state, so as to obtain the use condition of each audio port in the call state, and obtains the identifier of the audio output device used for call audio output in the corresponding call state, and the obtained audio output device identifier currently outputting audio forms a device list containing all the audio output device identifiers outputting audio, and whether the identifier corresponding to the earphone device exists or not is searched in the list, if so, the mobile terminal in the call state is considered to use the earphone device as the audio output device of the mobile terminal, and if not, whether the update event of the audio port occurs in the audio port of the mobile terminal or not is continuously monitored.
When the mobile terminal is in a call state and the call audio output device is a receiver device, detecting the touch condition of the screen to obtain the number of touch points, determining the number of areas mapped by capacitance change on the capacitive sensor on the screen according to the capacitive sensor and the multi-point touch function of the mobile terminal screen, obtaining the capacitance variation of each area, judging whether the capacitance variation exceeds a preset upper limit of capacitance variation one by one for each area, and when the capacitance variation of all the areas is smaller than the preset upper limit of capacitance variation, considering that all the touch areas are point contacts, wherein the number of the capacitance variation areas and the number of the touch points are consistent.
When the area with the capacitance value variation reaching or exceeding the capacitance value variation upper limit appears in all the areas, the screen of the mobile terminal is considered to have surface contact, such as palm, face or local skin of a human body contacting or approaching the screen. At this time, the number of the touch points on the screen of the mobile terminal is considered as the preset touch point number threshold of the mobile terminal.
The mobile terminal triggers the screen to automatically extinguish according to the number of touch points, starts the false touch prevention function, simulates the occurrence of a proximity event and/or a contact event when the mobile terminal is in a call state and takes the earphone device as a call audio output device and the touch points on the screen reach or exceed the number threshold of the touch points preset by the mobile terminal, and starts the false touch prevention function of the mobile terminal in a screen extinguishing mode.
