Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, the first determination unit may be referred to as a second determination unit, and similarly, the second determination unit may be referred to as a first determination unit, without departing from the scope of the present invention. Both the first judgment unit and the second judgment unit are judgment units, but they are not the same judgment unit.
Fig. 1 is a flowchart of a screen control method of a terminal in one embodiment. The screen control method of the terminal in this embodiment is described by taking the operation on the terminal as an example. As shown in fig. 1, the screen control method of the terminal includes steps 102 to 106.
Step 102: when a user holds a terminal in a call state, acquiring the screen state of the terminal.
The terminal can monitor the call state of the terminal through a telephone Manager (Telephony Manager). The phone manager is used for managing a terminal call state, acquiring terminal information (terminal equipment information, SIM card information and network information), intercepting a phone state (a call state service state, a signal strength state and the like) and calling a phone dialer to make a call.
Optionally, the terminal may further obtain a current call state of the terminal by reading a log, or monitor the call state of the terminal through Android broadcasting, or the like. It should be noted that the above listed manners for detecting whether the terminal is in a call state are only examples and are not limited.
The screen state comprises a screen-off state and a screen-on state. Specifically, the terminal can be determined to be in a screen-on state or a screen-off state in a manner that the Power Manager Service detects whether the screen is lighted. After the power receives the call of the bright and dark screen, the wakefulness state of the mobile phone is set first, and then the bright and dark screen broadcast is sent to inform other application mobile phones of being in the bright screen state or the dark screen state. It should be noted that the above list is an example and not a limitation for determining the screen status of the terminal, and the screen status of the terminal may be detected in other manners.
Step 104: and when the screen is in a screen-off state, detecting the attitude information of the terminal based on a sensor built in the terminal within a preset time.
When a user holds a terminal and places the terminal beside an ear to answer a call, in order to prevent the call state from being ended due to misoperation in the process of answering the call, the screen is kept in a screen-off state during the call.
The terminal is internally provided with a sensor for acquiring attitude information or running state information of the terminal, a proportional acceleration sensor, a magnetic sensor, a direction sensor, a gyroscope sensor, a gravity sensor, a linear acceleration sensor and the like. And light sensing sensors, pressure sensors, temperature sensors, proximity sensors and the like for assisting in acquiring other information of the terminal can be arranged in the terminal. When a user holds the terminal and places the terminal beside an ear to answer a call and the screen state of the terminal is a screen-off state, an acceleration sensor and a gyroscope sensor which are arranged in the terminal can acquire acceleration information and angular velocity information of the terminal.
It should be noted that the attitude information may be understood as position information based on a standard coordinate system of an acceleration sensor and a gyroscope sensor in the terminal within a preset time, and the position information may be characterized by acceleration of X, Y, Z triaxial components and angular velocity information of X, Y, Z triaxial components. Wherein the attitude information includes three-axis acceleration and three-axis rotation angle.
Step 106: and judging whether a display screen of the terminal faces to a face area of the user or not according to the posture information.
And judging whether the display screen of the terminal faces to the face area of the user or not according to the acquired attitude information. The face area can be understood as the face information of the user can be collected if the front camera is opened by the terminal. When a user holds the terminal to place the terminal beside the ear to answer the call, the acceleration sensor and the gyroscope in the terminal can detect the attitude information when the user holds the terminal to place the terminal beside the ear to answer the call, and when the user keeps the terminal away from the ear of the user, the terminal can also detect the attitude information of the action.
According to the gesture actions of the user in the call process, historical statistical data of the posture information of the terminal in the call process can be obtained. According to the historical statistical data, the gesture information of the terminal moving from the position close to the ear of the user to any position in the moving track facing the face area of the user can be obtained, and according to the historical statistical data, the preset gesture information of the terminal facing the face area of the user can be preset. In the moving process of the terminal, when the attitude information collected by the acceleration sensor and the gyroscope accords with the preset attitude information, the display screen of the terminal can be judged to face the human face area.
Step 108: and when the display screen of the terminal faces the face area, controlling the terminal to light up the screen.
When a user needs to use the terminal to display information such as time, call duration and the like in the call process, the screen needs to be lightened for the user to use. Judging whether the screen needs to be lightened or not based on the posture information in the screen-off conversation process, and controlling to lighten the screen when the posture information shows that the display screen of the terminal faces the face area.
According to the screen control method of the terminal, when the terminal is in a call state, whether the current terminal faces the face area of the user can be judged based on the attitude information of the terminal acquired by the sensor arranged in the terminal, when the terminal faces the face area, the terminal is controlled to be lightened, the situation that the distance sensor is shielded by other objects (non-human ears) in the call process and cannot be lightened in time can be avoided, screen lightening operation can be timely and accurately realized based on the attitude information acquired by the terminal, and the user experience degree is improved.
In one embodiment, the attitude information of the terminal is detected based on a sensor built in the terminal, and is mainly based on an acceleration sensor and a gyroscope built in the terminal. The acceleration sensor (accelerometer), also known as a Gravity sensor (G-sensor), is an MEMS sensor capable of sensing the magnitude of acceleration, and can obtain the acceleration from three different axial components (X, Y, Z three-axis components) through the acceleration, so as to inform the upper layer application of performing corresponding processing.
Due to the gravity of the earth, when the terminal is horizontally placed on a desktop, the three-axis component acquired by the acceleration sensor can be that the X axis is 0, the Y axis is 0, and the Z axis is 9.81 in default; when the terminal is placed on a desktop downwards, the default of an X axis is 0, the default of a Y axis is 0, and the default of a Z axis is-9.81; when the terminal inclines to the left, the X axis is a positive value; when the terminal inclines to the right, the X axis is a negative value; when the terminal inclines upwards, the Y axis is a negative value; when the terminal is tilted downward, the Y-axis is positive. If moved or tilted, the vertical gravitational acceleration is resolved into the X, Y, Z axis. The value of the X, Y, Z axis will change constantly as the terminal is rotated. That is, it can be understood that the terminal is in a coordinate system, and whether the terminal moves or rotates can be determined by determining the current values of the current X, Y, Z triaxial components.
A gyroscope (Gyro-sensor), also called an angular velocity sensor, measures a physical quantity, which is a rotational angular velocity in yaw and tilt, unlike an acceleration sensor. On the terminal, the complete 3D motion cannot be measured or reconstructed by only using the acceleration sensor, and only the axial linear motion can be detected. However, the gyroscope can well measure the rotating and deflecting actions, so that the actual actions of a user can be accurately analyzed and judged. The gyroscope and the acceleration sensor use the same coordinate system, wherein when the terminal horizontally rotates clockwise, the Z axis is a positive value; when the terminal rotates horizontally anticlockwise, the z axis is a negative value; when the terminal rotates to the left, the y axis is a negative value; when the terminal rotates rightwards, the y axis is a positive value; when the terminal rotates upwards, the x axis is a negative value; when the terminal is rotated down, the x-axis is positive.
Fig. 2 is a flowchart illustrating an embodiment of detecting attitude information of a terminal based on a sensor built in the terminal within a preset time.
In a preset time, detecting the attitude information of the terminal based on a sensor built in the terminal, wherein the method comprises the following steps:
step 202: and acquiring the preset time.
The preset time is related to factors of the use habit of the user and the age of the user.
The acquiring of the preset time specifically comprises: when the terminal starts the function of lifting hands and brightening the screen, the terminal prompts a user to demonstrate movement actions; when the movement action executed by the user is detected and the pre-movement condition is met, the time length for executing the movement action is saved, the saved time length is used as a time basis for identifying the next action of lifting or drawing out of the user, and meanwhile, the saved time length is defined as a first time length. Repeating the moving action, detecting whether the first time length can be correctly identified as the demonstration action or not, and if the first time length can be identified, taking the first time length as the preset time length, namely, the moving action can be completed within the preset time; if the mobile action cannot be identified, the user is prompted to indicate the mobile action again, the first time length is adjusted until the mobile action can be identified correctly, and the adjusted first time length is used as the preset time length. The movement action can be understood as an action from the user holding the terminal by hand to answer the phone call by placing the terminal near the ear to the display screen of the terminal facing the face area of the user.
Step 204: and acquiring the acceleration and the rotation angle of X, Y, Z triaxial components acquired by the acceleration sensor and the gyroscope within a preset time.
The acceleration sensor and the gyroscope can acquire the acceleration and the rotation angular velocity of the X, Y, Z triaxial components of the terminal. And when the terminal moves away from the ear, starting to acquire the attitude information of the terminal, taking the attitude information acquired at the moment as first attitude information, taking the moment as the starting moment of preset time, and continuously acquiring the attitude information of the terminal acquired by the acceleration sensor and the gyroscope within the preset time.
Further, the preset time may be set to 1 second, and within the time of 1 second, the acceleration of the X, Y, Z triaxial components of the terminal is acquired according to the acquisition frequency of the acceleration sensor. The gyroscope acquires the rotation angular velocity of the current terminal X, Y, Z with three-axis components, and performs integral calculation on the angular velocity from the starting time of the preset time to any time within the preset time, so as to continuously acquire the rotation angle of X, Y, Z three-axis components within the preset time. That is, the gyroscope will acquire the rotation angles of the X, Y, Z three-axis components of angular velocity in a preset time.
Step 206: and acquiring the attitude information according to the acceleration and the rotation angle.
And acquiring attitude information of the terminal in preset time according to the three-axis acceleration acquired by the acceleration and the three-axis rotation angle acquired by the gyroscope, wherein the attitude information comprises X, Y, Z three-axis component acceleration and X, Y, Z three-axis component rotation angle. According to the obtained information of the two dimensions of the three-axis component acceleration and the three-axis component rotation angle, the attitude information of the terminal can be accurately obtained, and whether the attitude information of the terminal faces to the face area of the user within the preset time can be accurately and timely judged.
Specifically, judging whether a display screen of the terminal faces a face area of a user according to the posture information includes:
step 302: and judging whether the variation of the acceleration of the Y-axis component in the preset time is larger than a preset value.
In the normal conversation process of a user, a display screen of the terminal faces towards the ear of the user, and at the moment, initial position information of the terminal can be acquired, namely, first posture information of the terminal is acquired; in the moving process of the terminal, the three-axis acceleration data acquired by the acceleration sensor of the terminal changes on at least one single-axis component. When the terminal moves to a face area facing the user, the final position information of the terminal, that is, the second posture information of the terminal, may be acquired. The time length from the initial position (first posture information) to the final position (second posture information) is a preset time, and the preset time can be obtained according to a machine learning method.
In this embodiment, whether the variation of the acceleration of the Y-axis component is greater than a preset value in the three-axis acceleration data collected by the acceleration sensor within a preset time is determined. It is understood that the acceleration of the Y-axis component thereof is an acceleration in the Y-axis direction.
Further, the preset value is 3m/s2When the terminal moves from the initial position to the final position, the variation of the Y-axis component is more than 3m/s2. The preset value may be determined according to information such as a usage habit of a user, a holding posture of a phone call, and the like, but is not limited thereto.
When the variation of the acceleration of the Y-axis component is greater than a preset value within a preset time, step 304 is executed: and judging whether the rotating angle of the Y-axis component in the preset time is larger than a preset angle or not. That is, when the acceleration of the axial component is greater than a preset value, it is determined whether the Y-axis rotation angle acquired by the gyroscope within the preset time is greater than a preset angle. It is understood that the Y-axis rotation angle is an angle of rotation around the Y-axis, wherein the coordinate systems of the gyroscope and the acceleration sensor are the same coordinate system.
Further, the preset angle is 15 degrees, and the variation of the acceleration of the Y axis is more than 3m/s in the preset time2If the rotation angle around the Y-axis is also greater than 15 degrees, it can be determined that the terminal has moved from the initial position (with the display screen of the terminal facing the user's ear) to the final position (with the display screen of the terminal facing the user's face). That is, step 306 may be considered: the display screen of the terminal faces the face area of the user. That is, the first posture information and the second posture information may be analyzed, and when the acceleration variation of the Y-axis component is greater than a preset value and the rotation angle of the Y-axis component is also greater than a preset angle, it is considered that the display screen of the terminal faces the face area of the user.
When the acceleration variation of the Y-axis component is smaller than the preset value, or the rotation angle of the Y-axis component is smaller than the preset angle, it is determined that step 308: the display screen of the terminal is not oriented to the face area of the user.
It should be noted that the order of the determination before and after the step 302 and the step 304 is not limited, and the step 304 may be performed in an alternative order, and the step 304 may be performed first, and when the determination result is yes, the step 302 may be performed, when the determination result is yes, the step 306 may be performed, and when the determination result is no, the step 308 may be performed.
In one embodiment, in order to ensure accuracy of the display screen of the terminal facing the face area of the user, in step 306, before the display screen of the terminal facing the face area of the user, the method further includes:
acquiring the current terminal triaxial component acceleration, and judging whether the triaxial component acceleration is within a preset range;
when the three-axis component accelerations are all within the preset range, step 306 is executed: the display screen of the terminal faces the face area of the user.
It will be appreciated that the predetermined range of three-axis component acceleration may beTo set as: -5m/s2<X axis<5m/s2，-2m/s2<Y-axis<9.8m/s2，0.5m/s2<Z axis<9.8m/s2. If the current three-axis component acceleration of the terminal is within the preset range, it can be considered that the display screen of the terminal faces the face area at this time.
The screen control method in the implementation can accurately judge the attitude information of the current terminal based on the acceleration and angular velocity data of the terminal acquired by the acceleration sensor and the gyroscope within the preset time, and further can accurately judge whether the display screen of the current terminal faces to the face area of the user; when the display screen of the terminal faces to the face area of the user, the terminal is controlled to be lightened.
In one embodiment, before acquiring the acceleration of the three-axis component acquired by the acceleration sensor within a preset time period, the method further includes:
step 200: and detecting whether the terminal shakes or not based on the acceleration sensor.
The terminal is provided with a screen lifting and brightening function switch, for example, the switch name is 'hand lifting and brightening', and the switch is used for turning on or off the screen lifting and brightening function. The terminal can receive an operation instruction input by a user on the setting interface to turn on or turn off the screen-up function, and the operation instruction can be at least one of touch operation, voice operation and key operation. The terminal can also intelligently switch the lifting wake-up switch according to different scenes, for example, the lifting wake-up function is turned off in a time period of 24: 00-8: 00, and the lifting wake-up function is turned on in other time periods.
When the terminal is turned on, the Motion detection function of the acceleration sensor is turned on, that is, the Acceleration Motion Detection (AMD) function of the acceleration sensor starts to operate, so as to collect the position information of the terminal, but the gyroscope for collecting the angular velocity is in a low power consumption state. And judging whether the terminal shakes or not according to whether the acceleration sensor detects that the acceleration of the three-axis component changes or not.
Step 201: and when the terminal shakes, the gyroscope is started to be in a working state.
When the acceleration sensor detects X, Y, Z that the acceleration of any one of the three axes is changed, it indicates that the terminal is jittered. Generally, the gyroscope is in a dormant state, when the terminal shakes, the main chip controls the gyroscope to be turned on, so that the gyroscope is in a working state, a data transmission channel with the gyroscope is started, and the rotation angle information acquired by the gyroscope is acquired.
In the screen control method of the terminal in this embodiment, the acceleration sensor and the gyroscope are not simultaneously turned on, and when the acceleration sensor detects that the three-axis acceleration of the terminal changes, the main chip and the gyroscope in the low power consumption state are restored to the operating state, so that power consumption can be saved.
Fig. 4 is a flowchart for controlling the terminal to light up the screen when the display screen of the terminal faces the face area in one embodiment.
When the display screen of the terminal faces the face area, controlling the terminal to light the screen, including:
step 402: and acquiring the contact person attributes of the call, wherein the contact person attributes comprise a private contact person, a common contact person and a system contact person.
When the terminal is in a call state, the contact person attribute for the call with the current user can be acquired. The contact attributes include private contacts, frequent contacts, and system contacts.
The terminal can be pre-established with a private contact information list, a common contact information list and a system contact information list, so that when the terminal calls passively or actively, the contact attributes of the contacts communicating with the user can be determined through the private contact information list, the common contact information list and the system contact information list.
It should be noted that the private contact is a contact that the user does not want to be known by people; the common contact persons are common contact persons and can be known by people; the system contact person can be a contact person generated by a service system such as a bank, an operator, insurance and the like.
Step 404: and determining a bright screen control strategy corresponding to the contact person attribute according to the mapping relation between the contact person attribute and the bright screen control strategy.
The contact persons with different contact person attributes correspond to different screen-off control strategies, and the mapping relation between the contact person attributes and the screen-on control strategies can be stored in the terminal in advance. The contact person attribute and the bright screen control strategy can be in a one-to-one mapping relationship or in a multi-pair mapping relationship. The bright screen control strategy comprises bright screen disguising contact information, bright screen display conversation interface and bright screen locking.
Specifically, the step of camouflaging the information of the contact by the bright screen can be understood as camouflaging the information of the contact.
Further, the screen-lighting disguised contact information includes:
and when the contact is a private contact, displaying the information of the contact as a strange number or a private number. The contact information includes the name, telephone number and other information of the contact. For example, the name of the private contact can be disguised as the name of the system contact such as "china unicom", "china mobile", "business recruitment bank", etc. The bright screen display of the call interface can be understood as normal display of the call interface, and at least one or more of information of the contact, passing time, recording, phone book, adding call, mute, hands-free or keyboard are displayed; the screen is lightened and locked, so that only the current time is displayed, and the screen is locked, thereby avoiding the call ending caused by misoperation.
Step 406: and carrying out screen lightening control processing on the terminal according to the determined screen lightening control strategy.
And carrying out screen lightening control processing on the terminal according to the determined screen lightening control strategy. If the contact person attribute of the contact person currently communicating with the user is a private contact person, the bright screen control strategy corresponding to the private contact person is a bright screen disguising contact person information. That is, when the user of the handheld terminal is talking with the private contact a, and in the process of talking, the terminal is placed beside the ear of the user (not using the earphone for talking), when the user is interfered by the external environment or the user needs to use other functions (viewing information, time, etc.) of the terminal, the user moves the terminal from beside the ear of the user to the face area of the user, the screen of the terminal can be automatically lighted, and meanwhile, in the process of lighting the screen, the information of the private contact can be disguised. For example, a may be replaced by "# # bank" or the telephone number of the private contact may be replaced by "955", the name of which corresponds to the telephone number. Certainly, the name and the telephone number of a may also be set in a customized manner according to the user's needs, and the way of disguising the information of the private contact is not further limited.
The screen control method in the embodiment can protect the information of the private contact, improves the flexibility of privacy protection, and has a good privacy protection effect.
