Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a control method, a control device, a storage medium and a mobile terminal. Any one of the control devices provided in the embodiments of the present application may be integrated in a mobile terminal, and the mobile terminal may be a server, or may be a terminal device, including a smart phone, a Pad, a wearable device, a robot, and the like. The mobile terminal is integrated with a proximity sensor and a direction sensor, and can simultaneously realize at least one of a telephone function or a voice function.

Referring to fig. 1, fig. 1 is a schematic flowchart of a control method provided in an embodiment of the present application, where the control method is applied to a mobile terminal, and the mobile terminal includes a direction sensor and a proximity sensor, and the control method includes the following steps.

When the mobile terminal starts a telephone function or a voice function, the proximity sensor detects the approach of the obstacle in a normal mode 101.

The mobile terminal starts a telephone function, which may be a telephone function corresponding to a telephone application integrated when the mobile terminal leaves a factory, a telephone function corresponding to a third party telephone application installed on the mobile terminal, or a telephone function existing in other forms on the mobile terminal. Starting a voice function, which can be starting a voice playing function on an instant messaging application program installed on the mobile terminal, for example, when the instant messaging application program receives voice, clicking to play the voice to start the voice function; or starting the voice function when the software such as recording on the mobile terminal detects the playing sound. And is not particularly limited.

When the mobile terminal starts a telephone function or a voice function, the proximity sensor is started, and the proximity sensor is used for detecting the approach of the shielding object. When the proximity sensor is started, the normal mode of the proximity sensor is started by default, and the proximity of the shielding object is detected by using the normal mode of the proximity sensor.

And 102, when the approaching of the shielding object is detected within the preset distance range corresponding to the screen-off condition, controlling the screen of the mobile terminal to be turned off, and starting the direction sensor.

And detecting the distance of the shielding object by using the normal mode of the proximity sensor, and determining that the proximity of the shielding object is detected when the distance is within a preset distance range corresponding to the screen extinguishing condition. It should be noted that the detected obstruction may be cream, oil stain, etc. on the mobile terminal, or may be the head of the user, and the user is ready to receive a call or a voice. It should be noted that the frost and oil stain on the mobile terminal may be adhered to the mobile terminal carelessly during the process of answering a call or answering a voice, for example, the mobile terminal is close to the face, so that the frost is adhered to the mobile terminal; in this case, the obstruction detected in the preset distance range corresponding to the screen-off condition is the head of the user. It may be that before the phone function or the voice function is started, the frost or oil stain is already on the mobile terminal, in this case, the obstruction detected in the preset distance range corresponding to the screen-off condition may be the frost or oil stain (the user does not answer the phone or the voice), or the head of the user.

When the shielding object is detected within a preset distance range corresponding to the screen-off condition, controlling the mobile terminal to screen off (screen off), namely forbidding the display screen of the mobile terminal, and turning off the display screen. The intuitive result is that no touch on the display screen is responded to and no content on the display screen is visible. It should be noted that, when the display screen is in the off-screen state, the mobile terminal may normally perform other functions. For example, the mobile terminal may play audio, may exchange data with a server, may perform voice calls with other users, and the like. If the approach of the shielding object is not detected within the preset distance range corresponding to the screen-off condition, then the step of detecting the approach of the shielding object by using the normal mode of the proximity sensor is executed.

And when the screen of the mobile terminal is controlled to be turned off, a direction sensor on the mobile terminal is started, and the direction of the mobile terminal is detected by the direction sensor. The direction sensor may be an acceleration sensor, such as a gravitational acceleration sensor; but also angular velocity sensors, such as gyroscopes; acceleration sensors and angular velocity sensors may also be included.

When the acceleration sensor is in an operating state, X, Y, Z triaxial acceleration components of the mobile terminal can be detected in real time. If the acceleration Sensor is a Gravity Sensor (G-Sensor), which is a MEMS Sensor capable of sensing the magnitude of acceleration, the acceleration from three different axial components (X, Y, Z three-axis components) can be obtained by the acceleration. When the mobile terminal is horizontally placed on a desktop, the three-axis components (X, Y and Z) of the acceleration are (0, 0 and 9.81); when the mobile terminal is placed on a desktop downwards, three-axis acceleration components (X, Y and Z) are (0, 0, -9.81); when the mobile terminal inclines to the left, the X axis of the acceleration is a positive value; when the mobile terminal inclines to the right, the X axis of the acceleration is a negative value; when the mobile terminal inclines upwards, the acceleration Y axis is a negative value; when the mobile terminal inclines downwards, the acceleration Y axis is a positive value. The value of the X, Y, Z axis is constantly changing as the mobile terminal is rotated. That is, it can be understood that the mobile terminal is in a coordinate system, and whether the mobile terminal moves or rotates can be determined by determining the current values of the current X, Y, Z triaxial components.

When a gyroscope (also called an angular velocity sensor) is in a working state, X, Y, Z three-axis rotation angular velocity of the mobile terminal can be detected in real time. The gyroscope can well measure the actions of rotation and deflection. The gyroscope and the acceleration sensor use the same coordinate system, wherein when the mobile terminal horizontally rotates clockwise, the Z axis is a positive value; when the mobile terminal horizontally rotates anticlockwise, the Z axis is a negative value; when the mobile terminal rotates leftwards, the Y axis is a negative value; when the mobile terminal rotates rightwards, the Y axis is a positive value; when the mobile terminal rotates upwards, the X axis is a negative value; when the mobile terminal rotates downward, the X-axis is positive.

103, when the direction change detected by the direction sensor meets the preset direction condition and the proximity sensor detects the approach of the shielding object within the preset distance range, starting a high power consumption mode of the proximity sensor, wherein the transmitting power corresponding to the high power consumption mode is greater than the transmitting power corresponding to the normal mode.

When the direction sensor is a gravitational acceleration sensor, the preset direction condition may be that a change value of an acceleration component of the at least one axis reaches a preset acceleration value. When the direction sensor is a gyroscope, the preset direction condition is that the angular velocity change value of at least one axis reaches a preset angular velocity value. When the direction sensor comprises a gravity acceleration sensor and a gyroscope, the preset direction condition is that the change value of the acceleration component of at least one axis reaches a preset acceleration value and the change value of the angular velocity of at least one axis reaches a preset angular velocity value, and the force acceleration sensor and the gyroscope are used at the same time to improve the detection accuracy. The preset angular velocity value and the preset acceleration value can be set according to actual conditions, for example, the preset acceleration value is 4, the preset angular velocity value is 10, and the like.

The preset direction condition is set to eliminate direction change caused by small-range adjustment of the mobile terminal by a user in the process of receiving a call or voice.

When the change of the direction value detected by the direction sensor for two consecutive times meets the preset direction condition, the mobile terminal is considered to move or rotate. Specifically, the method can be divided into two cases, when the detected blocking object in the preset distance range corresponding to the screen-off condition may be frost, oil stain or the like, and the detected direction change meets the preset direction condition, including a process that the mobile terminal is moving, such as a process that a user is preparing to receive a call or receiving voice, or a process that the mobile terminal moves along with the movement/motion of the user. When the detected sheltering object in the preset distance range corresponding to the screen-off condition is the head of the user, the detected direction change meets the preset direction condition, and the conditions comprise that the user finishes making a call, does not use a receiver mode to receive the voice any more or finishes receiving the voice and the like.

When the direction change detected by the direction sensor meets the preset direction condition and the proximity sensor detects the approach of the shielding object within the preset distance range, namely the direction change is large, and meanwhile, the proximity sensor detects the approach of the shielding object, then the high power consumption mode of the proximity sensor is started.

Understandably, the proximity sensor has two distinct modes of operation: the device comprises a normal mode and a large power consumption mode, wherein the transmitting power of the large power consumption mode is larger than the transmitting power corresponding to the normal mode. The high power consumption mode of the proximity sensor is started, and it is also understood that the mode of the proximity sensor is switched from the normal mode to the high power consumption mode. The mode of the proximity sensor is switched from a normal mode to a high power consumption mode so that the proximity sensor detects the approach of a shield using a larger transmission power to distinguish whether the case is due to the presence of a shield such as cream, oil stain, or the like, or the case is where the mobile terminal is approaching or moving away from the head of the user.

Wherein the step of initiating a high power mode of the proximity sensor comprises: sending a mode switching instruction to a register corresponding to the proximity sensor; and modifying the value of the register according to the mode switching instruction so as to switch the mode of the proximity sensor from the normal mode to the high-power-consumption mode. The proximity sensor switches from the normal mode to the high power mode by modifying the value of the corresponding register. And controlling the central processing unit to send a mode switching instruction to the register corresponding to the proximity sensor, and modifying the value of the register according to the mode switching instruction. The working current corresponding to the high power consumption mode of the proximity sensor is larger than the working current corresponding to the normal mode.

And 104, detecting the approach of the shielding object by using a large power consumption mode of the proximity sensor.

And when the mode of the proximity sensor is switched to the high power consumption mode, the high power consumption mode of the proximity sensor is utilized to detect the approach of the shielding object.

105, when the approaching of the shielding object is not detected within the preset distance range corresponding to the screen-off condition, controlling the mobile terminal to be on.

And when the direction change meets the preset direction condition and the approach of the shielding object is detected, starting a high power consumption mode.

When the mobile terminal is determined to be moving when the proximity of the shielding object is not detected within the preset distance range corresponding to the screen-off condition by using the high-power-consumption mode, the conditions that the user is preparing to answer a phone or answer a voice, the mobile terminal moves along with the movement/movement of the user (the movement is not the movement of answering the phone or answering the voice), and the like are included, at the moment, the mobile terminal does not approach the head of the user, so that the proximity of the shielding object is not detected by using the high-power-consumption mode (the shielding object is detected by using the normal mode because frost, oil stain and the like are adhered on the mobile terminal), and the screen of the mobile terminal is controlled to be lightened, so that the operation of the user on the mobile terminal is prevented from being influenced.

When the situation that the mobile terminal leaves the head is determined when the proximity of the shielding object is not detected within the preset distance range corresponding to the screen-off condition by using the high-power-consumption mode, the situation that a user makes a call and does not use an earphone mode to receive voice or finishes receiving voice, and the like, is determined, at the moment, the proximity of the shielding object is not detected even when the high-power-consumption mode is used (the shielding object is detected by using the normal mode because frost, oil stain and the like are adhered to the mobile terminal), and the screen is controlled to be lightened so as to solve the abnormal problem that the shielding object such as frost, oil stain and the like exists on the screen of the mobile terminal, and the screen is still in a turned-off state after the call is finished.

Wherein, control mobile terminal bright screen includes: and starting a display screen of the mobile terminal and lightening the display screen. The intuitive result is that the corresponding user touches on the display screen and can see the content on the display screen.

In an embodiment, after the step of controlling the mobile terminal to light up, the control method further includes: and turning off the direction sensor and turning off a high-power-consumption mode of the proximity sensor. When it is determined that the proximity of the blocking object is not detected by using the high power consumption mode, it may be determined to include a case where the mobile terminal is away from the head or a case where the mobile terminal is moving (the movement is a movement that is not receiving a call/receiving a voice), and at this time, the mobile terminal is controlled to be on, and the direction sensor is turned off, and the high power consumption mode of the proximity sensor is turned off to reduce the power consumption of the mobile terminal.

In this context, the closing of the direction sensor is understood to mean the function of the closing of the direction sensor. Turning off the high power mode of the proximity sensor may be understood as turning off the proximity sensor, and in one case, may be understood as switching the high power mode of the proximity sensor to the normal mode.

In one embodiment, as shown in fig. 1, the control method further includes step 106.

106, when the approach of the shielding object is detected within the preset distance range corresponding to the screen-off condition, saving the screen-off of the mobile terminal and keeping the starting state of the direction sensor.

And when the direction change meets the preset direction condition and the approach of the shielding object is detected, starting a high power consumption mode. When the high-power mode of the mobile terminal is utilized, the approach of the shielding object is detected within the preset distance range corresponding to the screen-off condition, and the method comprises the following steps: the method comprises the following steps that cream, oil stains and the like on the mobile terminal are too much, and the condition that the mobile terminal is close to the head of a user is almost the same as the condition that the mobile terminal is close to the head of the user, so that in the process that the mobile terminal moves (the movement is not the movement of answering a call/answering voice), or when the mobile terminal finishes receiving a call, finishes answering voice in an earphone mode and finishes answering voice, the direction change is detected to meet the preset condition, and the approach of a shielding object can be detected no matter in a normal mode or a high-power mode; further comprising: when a user answers a call or voice, the gesture is a standing gesture, and in the process of answering the call or voice, the gesture is changed, such as a lying gesture, so that the detected direction change meets the preset direction condition, and the approach of a shielding object can be detected no matter in a normal mode or a high-power mode.

When the high-power mode of the mobile terminal is utilized, when the approach of a shielding object is detected within a preset distance range corresponding to a screen-off condition, the screen of the mobile terminal is kept off, and the starting state of the direction sensor is kept, so as to detect the direction change, the approach of the shielding object and the like, namely, the step of starting the high-power mode of the proximity sensor when the direction change detected by the direction sensor meets the preset direction condition and the proximity sensor detects the approach of the shielding object within the preset distance range is executed.

When too much frost, oil stain and the like on the mobile terminal are different from the situation that the mobile terminal is close to the head of a user (the situation is almost impossible in real life), the frost and the oil stain on the mobile terminal can be removed, and the abnormal problem caused by the fact that the screen is still in a turned-off state due to the existence of shelters such as the frost and the oil stain on the screen of the mobile terminal can be solved.

In the embodiment of the application, when the approach of the shielding object is detected, the distance between the shielding object and the mobile terminal can be detected, and if the distance is within the preset distance range corresponding to the screen-off condition, the approach of the shielding object is determined to be detected.

The method comprises the steps of firstly detecting the approach of a shielding object through a normal mode of the mobile terminal, then starting a direction sensor of the mobile terminal, detecting the direction change of the mobile terminal through the direction sensor, starting a high-power-consumption mode of the proximity sensor only when the direction change meets a preset direction condition (the direction sensor) and the approach of the shielding object (the proximity sensor) is detected at the same time, detecting the shielding object through the high-power-consumption mode, and controlling the mobile terminal to be on when the high-power-consumption mode does not detect the approach of the shielding object, so that the abnormal problem caused by the fact that the mobile terminal leaves the head after the call is finished or the screen of the mobile terminal is still in a turned-off state in the moving process due to the existence of small-area shielding objects such as face cream, oil stain and the like on the screen of the mobile terminal is solved. When the approach of the shielding object is detected by using the high-power-consumption mode, the mobile terminal is controlled to keep the screen-off state, and the starting state of the direction sensor is kept, so that the situation that the posture of the mobile terminal corresponds to the change of the posture of a user in the process of answering a call or answering voice can be solved.

In an embodiment, the proximity sensor may be an infrared sensor or an ultrasonic or the like type sensor or the like. The proximity sensor can emit a detection signal, and the emitted detection signal penetrates through the display screen and then is emitted to the outside. The detection signal is reflected by an external object to generate a reflection signal, and the reflection signal penetrates through the display screen and then enters the proximity sensor. Thus, the proximity sensor can detect the intensity value of the received reflected signal.

Correspondingly, as shown in fig. 2, a schematic flow chart of a control method provided in an embodiment of the present application is shown, where the control method includes the following steps.

When the mobile terminal starts a telephone function or a voice function, the proximity sensor detects the approach of the blocking object in a normal mode.

202, when the approaching of the shielding object is detected within the preset distance range corresponding to the screen-off condition, controlling the mobile terminal to screen-off, and starting the direction sensor.

203, when the direction change detected by the direction sensor meets the preset direction condition and the proximity sensor detects the approach of the shielding object within the preset distance range, starting a high power consumption mode of the proximity sensor, wherein the transmitting power corresponding to the high power consumption mode is larger than the transmitting power corresponding to the normal mode.

Proximity of the obstruction is detected 204 using a high power mode of the proximity sensor.

205, obtaining a first reflected signal intensity value received by the proximity sensor when controlling the mobile terminal to turn off the screen and obtaining a second reflected signal intensity value received when detecting the obstruction by using the high power consumption mode of the proximity sensor.

The proximity sensor detects a corresponding reflected signal due to an infrared sensor or an ultrasonic wave or the like. Specifically, a first reflected signal strength value received by the proximity sensor when the mobile terminal is turned off is obtained, and a second reflected signal strength value received by the proximity sensor when the high power consumption mode is used for detection is obtained. The preset intensity difference value refers to the maximum value of the intensity error corresponding to the detection of the same obstruction twice.

206, detecting whether the intensity difference corresponding to the first and second reflected signal intensity values exceeds a preset intensity difference. If yes, determining that the approach of the shielding object is not detected within a preset distance range corresponding to the screen-off condition, and executing step 207; if not, determining that the approach of the shielding object is detected within the preset distance range corresponding to the screen-off condition, and executing step 208.

If the intensity difference corresponding to the first reflection signal intensity value and the second reflection signal intensity value exceeds the preset intensity difference, it means that the shielding objects corresponding to the first reflection signal intensity value obtained by reflection and the second reflection signal intensity value obtained by reflection are not the same shielding object or the second reflection signal intensity value is almost zero, and it is possible that the mobile terminal leaves the head of the user; if the intensity difference corresponding to the first reflected signal intensity value and the second reflected signal intensity value does not exceed the preset intensity difference, it means that the shielding objects corresponding to the first reflected signal intensity value and the second reflected signal intensity value obtained by reflection may be the same shielding object, like the head of the user. It is understood that the first reflected signal strength value obtained by the proximity sensor detecting the head of the user in the normal mode and the second reflected signal strength value obtained by the proximity sensor detecting the head of the user in the high power consumption mode are the same or not much different.

And 207, controlling the mobile terminal to light the screen, turning off the direction sensor and turning off a high-power-consumption mode of the proximity sensor.

And 208, keeping the mobile terminal off the screen and keeping the starting state of the direction sensor.

If the intensity difference corresponding to the first reflected signal intensity value and the second reflected signal intensity value exceeds a preset intensity value, controlling the mobile terminal to light the screen, closing the direction sensor and closing the high-power-consumption mode of the proximity sensor; the abnormal problem caused by the fact that small-area shelters such as face cream and oil stains exist on the screen of the mobile terminal and the mobile terminal is still in a turned-off state after the mobile terminal leaves the head screen after the call is finished is solved. If the intensity difference corresponding to the first reflection signal intensity value and the second reflection signal intensity value does not exceed the preset intensity value, the screen of the mobile terminal is kept turned off, and the starting state of the direction sensor is kept; the method can solve the corresponding situation of the gesture of the mobile terminal along with the change of the gesture of the user in the process of answering the call or answering the voice.

In some embodiments, in order to prevent the situation of a non-answered phone or a non-answered voice and the like from influencing the detection result, the motion track of the mobile terminal during the call function or the voice function is combined to determine whether the phone function or the voice function is used and/or whether the phone function or the voice function is ended.

Specifically, as shown in fig. 3, a schematic flow chart of the control method provided in the embodiment of the present application is shown.

The control method includes the following steps.

301, obtaining a motion trajectory when the mobile terminal uses a call function or a voice function each time, and when the number of times of repeated occurrence of some motion trajectories of the mobile terminal reaches a first preset number of times, determining that the motion trajectory is a used motion trajectory when the call function or the voice function of the mobile terminal is currently used; and acquiring a motion track when the mobile terminal finishes the call function or the voice function each time, and judging that the motion track is a finishing motion track when the call function or the voice function of the mobile terminal is finished at present when the repeated occurrence times of some motion tracks of the mobile terminal reach a second preset time.

The first preset number and the second preset number may be the same or different, for example, 5. Some motion tracks comprise a certain motion track or a plurality of motion tracks and the like.

The motion trail of the mobile terminal in the preset time period when the mobile terminal uses the call function or the voice function and the motion trail of the mobile terminal when the mobile terminal finishes the call function or the voice function can be obtained. Such as a corresponding motion trajectory within 10 days.

The used motion track can be a corresponding motion track from receiving incoming calls to placing at the ear for receiving, can also be a corresponding motion track from opening a telephone application program to placing at the ear for receiving, and can also be a similar motion track for expressing a corresponding motion track from a state of starting receiving/starting making calls to a state of placing at the ear for receiving. If the corresponding motion track is between the taking-up state from the desktop and the answering state of the phone; the corresponding motion track from the use state of watching the display screen to the answering state of answering the phone, and the like. The dashed line shown in fig. 4a is a schematic diagram of a motion trajectory used in the embodiment of the present application.

The ending motion trail refers to a corresponding motion trail from an ending listening state for ending listening beside the ear to a stable state after leaving the ear. If the corresponding motion track is from the end listening state of the ear listening to the position between the desktops; and the corresponding motion track from the end listening state of ending the ear listening to the use state of watching the display screen, and the like. The dashed line shown in fig. 4b is a schematic diagram of an ending motion trajectory provided in the embodiment of the present application.

It should be noted that fig. 4a and 4b are only one example, and do not constitute a limitation of the motion trajectory. Wherein the motion trail can be detected by a direction sensor, such as a gravitational acceleration sensor and a gyroscope.

And 302, setting and storing the using motion track as a preset approaching track, and setting and storing the ending motion track as a preset far track.

When the approach of the shielding object is detected in the preset distance range corresponding to the screen-off condition and the motion track of the mobile terminal is detected to be the preset approach track, the user is in the process of answering/making a call and answering voice. Thus, the situation that the mobile terminal moves (not the process of receiving/making a call and receiving voice) is eliminated.

If the approaching of the shielding object is detected within the preset distance range corresponding to the screen-off condition, but the motion track of the mobile terminal is not the preset approaching track, the shielding object such as cream, oil stain and the like may exist on the mobile terminal, and the mobile terminal is controlled to keep the original state unchanged. If the original state is bright screen, the screen is kept bright.

And when the approach of the shielding object is detected within the preset distance range corresponding to the screen-off condition, then a step of detecting the approach of the shielding object by using a normal module of the proximity sensor and detecting the motion track of the mobile terminal is executed.

And 305, when the direction change detected by the direction sensor meets a preset direction condition and the proximity sensor detects the approach of the shielding object within a preset distance range, starting a high power consumption mode of the proximity sensor.

In this embodiment, when the direction change detected by the direction sensor satisfies the preset direction condition, the following conditions are included: ending the call, ending the answering voice, ending the receiver state answering voice and the like; during the conversation/voice process of the user, the mobile terminal can move along with the change of the user posture.

Proximity of the obstruction is detected 306 using a high power mode of the proximity sensor.

307, when the approach of the shielding object is not detected in the preset distance range corresponding to the screen-off condition and the motion track of the terminal is detected to be a preset away track, controlling the mobile terminal to turn on the screen, turning off the direction sensor and turning off the high-power-consumption mode of the proximity sensor; otherwise, keeping the mobile terminal off the screen and keeping the starting state of the direction sensor.

When the approach of the shielding object is not detected in the preset distance range corresponding to the screen-off condition and the motion track of the terminal is detected to be the preset far track, the situation that the mobile terminal can move along with the change of the posture of the user in the conversation/voice process of the user can be eliminated; namely, the corresponding situation is the situation of ending the call, ending the answering voice in the receiver state, etc., in which the mobile terminal is controlled to light up, and the direction sensor is turned off, and the high power consumption mode of the proximity sensor is turned off.

Otherwise, the situation is not the situation corresponding to the situation that the approach of the shielding object is not detected in the preset distance range corresponding to the screen-off condition and the motion track of the terminal is detected to be the preset far track.
