Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
The proximity sensor is an indispensable part of the mobile terminal, and the main function of the proximity sensor is to control the screen of the mobile terminal to be turned on or off when a user performs voice-type communication, for example, during a call or a WeChat voice, the screen of the mobile terminal is turned off when the mobile terminal is close to an ear, and the screen of the mobile terminal is turned on when the mobile terminal is far away from the ear, so that the purposes of saving power and preventing false touch are achieved.
With the screen occupation ratio of mobile terminals becoming higher and higher, full-screen mobile terminals have become the trend of mobile terminal hardware configuration. However, conventional proximity sensors are no longer suitable for full-screen mobile terminals. Under the circumstances, technical personnel in the field of cost need to solve the technical problem of how to realize the proximity detection of the full-screen mobile terminal. At present, the skilled person proposes two approaches for detecting the proximity of a full-screen mobile terminal: an ultrasound protocol and a touch screen protocol.
The detection principle of the ultrasonic scheme is as follows: the receiver sends out an ultrasonic signal, and whether an object is close to the mobile terminal is detected according to the ultrasonic signal returned by the microphone, however, the ultrasonic signal has no directivity, and the object is also detected to be close to the mobile terminal from the back or the top of the mobile terminal, so that the screen of the mobile terminal is mistakenly turned off.
The detection principle of the touch screen scheme is as follows: whether an object is close to the mobile terminal is detected through the change of the capacitance value of the touch screen, however, the detection distance of the touch screen is short, so that the mobile terminal does not extinguish the screen when the screen is supposed to be extinguished, and the function of preventing mistaken touch cannot be realized.
In order to solve the above technical problem, embodiments of the present invention provide a proximity detection method and a mobile terminal.
The approach detection method provided by the embodiment of the present invention is first described below.
It should be noted that the method provided by the embodiment of the present invention is applicable to a mobile terminal, and in practical application, the mobile terminal may include: smart phones, tablet computers, personal digital assistants, and the like, which are not limited in the embodiments of the present invention.
Fig. 1 is a flowchart of a proximity detection method according to an embodiment of the present invention, in which a proximity sensor is formed by an ultrasonic sensor and a touch screen in a mobile terminal, as shown in fig. 1, the method may include the following steps: step 101 and step 102, wherein,
in step 101, an ultrasonic sensor of the mobile terminal is started for proximity detection, and a touch screen of the mobile terminal is started for proximity detection.
In the embodiment of the invention, the problem that inaccurate detection is easy to generate when the mobile terminal is only subjected to proximity detection by the ultrasonic sensor of the mobile terminal is considered, the problem that screen should not be extinguished but is extinguished is easy to generate when the mobile terminal is only subjected to proximity detection by the touch screen of the mobile terminal, and the problem that screen should be extinguished but is not extinguished is easy to generate when the mobile terminal is subjected to proximity detection by the ultrasonic sensor of the mobile terminal.
For the situation, the embodiment of the invention can perform proximity detection on the mobile terminal through the ultrasonic sensor of the mobile terminal, and also perform proximity detection on the mobile terminal through the touch screen of the mobile terminal, and integrate the proximity detection result of the ultrasonic sensor and the proximity detection result of the touch screen to determine the proximity detection state of the mobile terminal, so as to solve the problems of 'screen should not be turned off but turned off' caused by only using the ultrasonic sensor and 'screen should be turned off but not turned off' caused by only using the touch screen at present, thereby improving the accuracy of the proximity detection of the mobile terminal.
Since the proximity detection principle of the ultrasonic sensor in the embodiment of the present invention is the same as that of the ultrasonic sensor in the prior art, and the proximity detection principle of the touch screen in the embodiment of the present invention is the same as that of the touch screen in the prior art, details thereof are not repeated herein.
In the embodiment of the invention, the proximity detection result of the ultrasonic sensor can be divided into the proximity with an object and the proximity without an object, and the proximity detection result of the touch screen can also be divided into the proximity with an object and the proximity without an object. In practical applications, the approach detection result "with an object approaching" may be simply referred to as "approaching", and the approach detection result "without an object approaching" may be simply referred to as "departing".
In the embodiment of the invention, the touch screen of the mobile terminal can be started for proximity detection while the ultrasonic sensor of the mobile terminal is started for proximity detection; or in consideration of the power consumption of the mobile terminal, the ultrasonic sensor of the mobile terminal may be started to perform proximity detection, and when the proximity detection result of the ultrasonic sensor indicates that an object is approaching, the touch screen of the mobile terminal may be started to perform proximity detection.
In the embodiment of the invention, the approach detection result of the ultrasonic sensor can be stored in real time in the process of carrying out the approach detection on the ultrasonic sensor of the mobile terminal; in the process of proximity detection of the touch screen of the mobile terminal, the proximity detection result of the touch screen can be stored in real time, so that the real proximity state of the mobile terminal can be determined in real time by combining the proximity detection result of the ultrasonic sensor and the proximity detection result of the touch screen.
In the embodiment of the present invention, when proximity detection is performed through a touch screen of a mobile terminal, considering that inaccurate detection results are easily caused if the entire touch screen is used for proximity detection, a partial area on the touch screen may be defined for proximity detection, and at this time, the step of starting the touch screen for proximity detection may specifically include: and starting a preset area on the touch screen for proximity detection, wherein the preset area comprises at least one edge area of the touch screen. For example, the preset area is an 1/5 area on the touch screen.
In step 102, if both the proximity detection result of the ultrasonic sensor and the proximity detection result of the touch screen are that an object is approaching, it is determined that an object is approaching the mobile terminal.
In the embodiment of the invention, if the proximity detection result of the ultrasonic sensor indicates that no object is close or the proximity detection result of the touch screen indicates that no object is close, it is determined that no object is close to the mobile terminal.
Specifically, if the proximity detection result of the ultrasonic sensor is that no object is close and the proximity detection result of the touch screen is that no object is close, it is determined that no object is close to the mobile terminal; if the proximity detection result of the ultrasonic sensor is that no object is close and the proximity detection result of the touch screen is that an object is close, determining that no object is close to the mobile terminal; if the proximity detection result of the ultrasonic sensor is that an object approaches and the proximity detection result of the touch screen is that no object approaches, determining that no object approaches the mobile terminal; and if the proximity detection result of the ultrasonic sensor is that an object approaches and the proximity detection result of the touch screen is that the object approaches, determining that the object approaches the mobile terminal.
For the convenience of visual understanding, the above several cases are described by using a table, which is specifically shown in the following table 1:
TABLE 1
Therefore, in the embodiment of the invention, only when the proximity detection result of the ultrasonic sensor and the proximity detection result of the touch screen are both that an object approaches, the object is determined to approach the mobile terminal, and no object approaches the mobile terminal under other conditions, so that the problems that the screen should not be turned off but turned off and the screen should be turned off but not turned off, which are generated by only using the ultrasonic sensor and the touch screen in the prior art, are solved, and the accuracy of the proximity detection of the mobile terminal is improved.
In the embodiment of the invention, in a telephone conversation or voice chat scene, if an object is determined to be close to the mobile terminal, the mobile terminal is indicated to be turned off, so that the purposes of preventing mistaken touch and saving electricity are achieved. When the phone call is over or the voice chat is over, the ultrasonic sensor may be turned off.
It can be seen from the above embodiments that, in this embodiment, the proximity detection function of the proximity sensor can be simulated through the cooperation of the ultrasonic sensor and the touch screen, and proximity detection is performed on the full-screen mobile terminal. Compared with the prior art, in the embodiment of the invention, when the ultrasonic sensor is arranged in the mobile terminal, the window opening or the hole opening is not needed in the front glass area of the mobile terminal, and the occupied space is small, so that the ultrahigh screen ratio of the mobile terminal is favorably realized; and because the ultrasonic sensor and the touch screen both have the proximity detection function, the detection results of the ultrasonic sensor and the touch screen are synthesized to carry out proximity detection of the full-screen mobile terminal, so that the deviation and the defect generated when the single sensor is used for carrying out the proximity detection can be overcome, and the proximity detection accuracy of the full-screen mobile terminal can be improved.
Fig. 2 is a flowchart of a proximity detection method according to another embodiment of the present invention, in order to further improve the accuracy of proximity detection, in an embodiment of the present invention, gesture detection on a mobile terminal may be added on the basis of the embodiment shown in fig. 1, in this case, a proximity sensor may be formed by an ultrasonic sensor, a touch screen, and a gesture sensor in the mobile terminal, as shown in fig. 2, and the method may include the following steps: step 201 and step 202, wherein,
in step 201, an ultrasonic sensor of the mobile terminal is started for proximity detection, a touch screen of the mobile terminal is started for proximity detection, and a gesture sensor of the mobile terminal is started for gesture detection of the mobile terminal.
In the embodiment of the invention, the problem that the screen should not be turned off but turned off is probably caused when the mobile terminal is in a flat-up screen posture and if a user contacts the upper part of the touch screen of the mobile terminal, the ultrasonic sensor of the mobile terminal and the touch screen perform proximity detection. Therefore, in order to improve the accuracy of the proximity detection of the mobile terminal in the scene of the flat-top screen posture of the mobile terminal, the posture detection of the mobile terminal can be increased.
In the embodiment of the invention, the gesture of the mobile terminal can be detected through the gesture sensor of the mobile terminal, the gesture sensor can be composed of an acceleration sensor and a gyroscope, wherein the acceleration sensor can acquire triaxial gravity acceleration data of the mobile terminal, the gyroscope can acquire triaxial angular velocity data of the mobile terminal, and the gesture of the mobile terminal is determined based on the acquired triaxial gravity acceleration data and triaxial angular velocity data. In practical application, the gesture of the mobile terminal may include: square, rotated, tilted, etc.
In combination with the application scenario (i.e. improving the accuracy of the proximity detection of the mobile terminal when the mobile terminal is in the posture of being laid flat with the screen facing upwards) of the embodiment of the present invention, the posture of the mobile terminal can be divided into two types: a screen-up lie attitude and an attitude other than a screen-up lie attitude (for ease of description, referred to as an unknown attitude).
In the embodiment of the invention, the ultrasonic sensor of the mobile terminal can be started for proximity detection, the touch screen of the mobile terminal can be started for proximity detection, and the attitude sensor of the mobile terminal can be started for attitude detection of the mobile terminal; or in consideration of the power consumption problem of the mobile terminal, the ultrasonic sensor of the mobile terminal may be started to perform proximity detection, when the proximity detection result of the ultrasonic sensor indicates that an object is approaching, the touch screen of the mobile terminal is started to perform proximity detection, and when the proximity detection result of the touch screen indicates that an object is approaching, the attitude sensor of the mobile terminal is started to perform attitude detection on the mobile terminal.
In the embodiment of the invention, the approach detection result of the ultrasonic sensor can be stored in real time in the process of carrying out the approach detection on the ultrasonic sensor of the mobile terminal; in the process of proximity detection of the touch screen of the mobile terminal, the proximity detection result of the touch screen can be stored in real time; in the process of detecting the gesture of the mobile terminal by the gesture sensor of the mobile terminal, the approach detection result of the gesture sensor can be stored in real time, so that the real approach state of the mobile terminal can be determined in real time by combining the approach detection result of the ultrasonic sensor, the approach detection result of the touch screen and the gesture detection result of the gesture sensor.
In step 202, if the proximity detection result of the ultrasonic sensor and the proximity detection result of the touch screen are both the object approaching posture and the posture detection result of the posture sensor is the posture of the mobile terminal outside the upward square posture of the screen, it is determined that the object approaches the mobile terminal.
In the embodiment of the invention, if the proximity detection result of the ultrasonic sensor indicates that no object is close, or the proximity detection result of the touch screen indicates that no object is close, or the gesture detection result of the gesture sensor indicates that the mobile terminal is in a screen-up square gesture, it is determined that no object is close to the mobile terminal.
Specifically, if the proximity detection result of the ultrasonic sensor is that an object is approaching, the proximity detection result of the touch screen is that an object is approaching, and the detection result of the attitude sensor is that the screen is horizontally placed upwards, it is determined that no object is approaching the mobile terminal;
if the proximity detection result of the ultrasonic sensor is that an object approaches, the proximity detection result of the touch screen is that no object approaches, and the detection result of the attitude sensor is that the screen is horizontally placed upwards, determining that no object approaches the mobile terminal;
if the proximity detection result of the ultrasonic sensor is that an object approaches, the proximity detection result of the touch screen is that no object approaches, and the detection result of the attitude sensor is an unknown attitude, determining that no object approaches the mobile terminal;
and if the proximity detection result of the ultrasonic sensor is that no object approaches, the proximity detection result of the touch screen is that no object approaches, and the detection result of the attitude sensor is that the unknown attitude/the attitude of the screen which is horizontally placed upwards exists, determining that no object approaches the mobile terminal.
For the convenience of visual understanding, the above several cases are described by using a table, which is specifically shown in the following table 2:
TABLE 2
Therefore, in the embodiment of the invention, only when the proximity detection result of the ultrasonic sensor and the proximity detection result of the touch screen are that the object approaches and the detection result of the attitude sensor is that the mobile terminal is in an attitude (namely unknown attitude) other than the attitude in which the screen is horizontally placed upwards, the object is determined to approach the mobile terminal, and no object is determined to approach the mobile terminal under other conditions, so that the accuracy of the proximity detection of the mobile terminal is improved.
In the embodiment of the invention, in a telephone conversation or voice chat scene, if an object is determined to be close to the mobile terminal, the mobile terminal is indicated to be turned off, so that the purposes of preventing mistaken touch and saving electricity are achieved. When the phone call is over or the voice chat is over, the ultrasonic sensor may be turned off.
It can be seen from the above embodiments that, in this embodiment, the proximity detection function of the proximity sensor can be simulated through the cooperative work of the ultrasonic sensor, the touch screen and the attitude sensor, and the proximity detection is performed on the full-screen mobile terminal. Compared with the prior art, in the embodiment of the invention, when the ultrasonic sensor is arranged in the mobile terminal, the window opening or the hole opening is not needed in the front glass area of the mobile terminal, and the occupied space is small, so that the ultrahigh screen ratio of the mobile terminal is favorably realized; and because the ultrasonic sensor and the touch screen both have the proximity detection function, the attitude sensor can detect the attitude of the mobile terminal, and the proximity detection result of the ultrasonic sensor, the proximity detection result of the touch screen and the detection result of the attitude sensor are integrated to carry out proximity detection of the full-screen mobile terminal, so that the deviation and the defect generated when the single sensor is used for carrying out the proximity detection can be overcome, and the proximity detection accuracy of the full-screen mobile terminal can be improved.
