The following takes a terminal device as an example to illustrate the proximity detection method provided by the embodiment of the present invention.

In the traditional technology, the proximity detection method based on the ultrasonic detection scheme, since the ultrasonic signal has no directionality, when other objects approach the terminal device from other surfaces (the side, the top, or the back of the screen, etc.) The screen is mistakenly turned off due to the detection of being blocked, resulting in inconvenience for the user to operate.

Referring to FIG. 2, an embodiment of the present invention provides a proximity detection method, which is applied to a terminal device, and the method may include the following steps 201-202.

Step 201: The terminal device acquires state information of the terminal device when it is determined according to the ultrasonic sensor of the terminal device that there is a first object blocking the terminal device within a first preset distance.

The status information is used to determine whether the first screen of the terminal device is blocked by the first object.

The first preset distance is a distance preset according to an actual use requirement, which is not limited in the embodiment of the present invention.

Exemplarily, the terminal device can transmit an ultrasonic signal through an ultrasonic sensor, and receive the reflected ultrasonic signal through the ultrasonic sensor; , the embodiment of the present invention is not limited), then it is determined that there is a first object within the first preset distance that blocks the terminal device; otherwise, it is determined that there is no object that blocks the terminal device.

Exemplarily, the terminal device can send an ultrasonic signal through an ultrasonic sensor and obtain the sending time; receive the ultrasonic signal and obtain the receiving time; determine the distance of the measured object according to the difference between the receiving time and the sending time; When the distance is less than the first preset distance, it is determined that there is a first object blocking the terminal device within the first preset distance, otherwise, it is determined that there is no object blocking the terminal device.

In this embodiment of the present invention, the method for detecting that the terminal device determines that the terminal device is blocked by a first object within the first preset distance according to the ultrasonic sensor is not limited. For details, reference may be made to any related technology, which is not repeated in this embodiment of the present invention.

Optionally, the state information includes at least one of the following: gravitational acceleration information of the terminal device, and angular velocity information of the terminal device.

When the terminal device determines according to the state information that the first screen is blocked by the first object, the terminal device controls the first screen to switch from the bright-screen state to the off-screen state.

When the terminal device determines according to the state information that the first screen is not blocked by the first object, it can be divided into the following two cases:

In the first case, if the terminal device is a single-screen terminal device, when the terminal device determines according to the state information that the first screen is not blocked by the first object, the terminal device keeps the first screen in a bright screen state.

In the second case, the terminal device is a multi-screen terminal device. If the terminal device determines, according to the status information, that the second screen is blocked by the first object (the determination method is similar to that of determining that the first object blocks the first screen, this embodiment of the present invention does not allow the screen to be blocked by the first object). Repeat), the terminal device controls the second screen to switch from the bright-screen state to the off-screen state; if the terminal device determines according to the state information that the first object does not block any screen of the terminal device, the terminal device controls the screen in the bright-screen state. Keep the screen on.

Step 202: The terminal device controls the first screen to be switched from a bright screen state to an off screen state when it is determined that the first screen is blocked by the first object.

In this embodiment of the present invention, the terminal device controls the first screen to be switched from a bright-screen state to an off-screen state when it is determined that the first screen is blocked by the first object. Then, when an object blocks the first screen in the bright screen state, the occurrence of false touches can be avoided.

An embodiment of the present invention provides a method for proximity detection, in which a terminal device can acquire state information of the terminal device when it is determined according to an ultrasonic sensor of the terminal device that there is a first object blocking the terminal device within a first preset distance , the status information is used to determine whether the first screen of the terminal device is blocked by the first object; if it is determined that the first screen is blocked by the first object, control the first screen to switch from the bright screen state to the off screen state . Through this solution, when the ultrasonic sensor determines that the first object is blocking the terminal device, it can combine the status information of the terminal device to determine whether the first object is blocking the first screen; when it is determined that the first object is blocking the first screen In the case of the terminal device, the terminal device can control the first screen to be switched from the bright screen state to the off screen state, so that the occurrence of false touches can be avoided when a foreign object blocks the first screen of the terminal device in the bright screen state. The ultrasonic detection and the state detection of the terminal device can accurately determine that the first screen of the terminal device in the bright screen state is blocked, which improves the accuracy of the ultrasonic detection solution for detecting the blocked screen of the terminal device.

Optionally, after the terminal device acquires the state information of the terminal device, the terminal device needs to determine whether the first screen is blocked by the first object according to the state information.

Exemplarily, with reference to FIG. 2 , as shown in FIG. 3 , after step 201 , the proximity detection method provided by the embodiment of the present invention may further include the following steps 203 to 205 .

Step 203: The terminal device determines whether the state information satisfies the target condition.

Wherein, the target condition includes at least one of the following: the gravitational acceleration information is within a first range, and the angular velocity information is within a second range.

In the case where the terminal device determines that there is a first object blocking the terminal device within the first preset distance, if the gravitational acceleration information is within the first range, it can be determined that the first screen is blocked by the first object. The first range may be preset or acquired in real time, which is not limited in this embodiment of the present invention. In the embodiment of the present invention, if the gravitational acceleration information is within the first range, the state information satisfies the target condition.

In the case where the terminal device determines that there is a first object blocking the terminal device within the first preset distance, if the angular velocity information is within the second range, it can be determined that the first screen is blocked by the first object. The second range may be preset or acquired in real time, which is not limited in this embodiment of the present invention. In the embodiment of the present invention, if the angular velocity information is within the second range, the state information satisfies the target condition.

In the case where the terminal device determines that there is a first object blocking the terminal device within the first preset distance, if the gravitational acceleration information is within the first range and the angular velocity information is within the second range, it can be determined that the first object blocks the terminal device is the first screen. The first range and the second range may be preset or acquired in real time, which is not limited in this embodiment of the present invention. In the embodiment of the present invention, if the gravitational acceleration information is within the first range and the angular velocity information is within the second range, the state information satisfies the target condition.

Exemplarily, the terminal device can calculate the posture and gesture action of the terminal device according to the state information of the terminal device (such as the three-axis gravitational acceleration data of the mobile phone collected by the acceleration sensor and the three-axis angular velocity data collected by the gyroscope), and a gesture is defined here. and three gestures:

a) Pick up the terminal device and approach the ear gesture (referred to as answering gesture);

b) Vertical placement posture (that is, the posture when the terminal device is placed near the ear);

c) The screen is up and flat;

d) Unknown pose.

Combining the ultrasonic sensor to determine whether there is an object blocking the terminal device within the first preset distance (yes if there is an object blocking, no if there is no object blocking), and the gesture and attitude information (status information) reported by the inertial sensor (gravity and gyroscope) , to determine whether there is an object blocking the first screen (Yes if the first screen is blocked, and No if the first screen is not blocked), as shown in the following table.

According to the above table, it can be known that when the ultrasonic sensor determines that there is an object blocking the terminal device, only when the terminal device is in the answering gesture or vertical posture, it can be determined that the first screen is blocked.

When the state change information satisfies the target condition, the following step 204 is performed; when the state change information does not satisfy the target condition, the following step 205 is performed.

Step 204: The terminal device determines that the first screen is blocked by the first object.

When the state information satisfies the target condition, the terminal device determines that the first screen is blocked by the first object.

Step 205: The terminal device determines that the first screen is not blocked by the first object.

In the case that the state information does not meet the target condition, the terminal device determines that the first screen is not blocked by the first object.

Optionally, before the terminal device determines according to the ultrasonic sensor of the terminal device that there is a first object blocking the terminal device within the first preset distance, the terminal device needs to turn on the ultrasonic sensor first.

In this embodiment of the present invention, the terminal device can quickly determine whether the first screen is blocked by the first object according to whether the state information satisfies the target condition.

Exemplarily, with reference to FIG. 3 , as shown in FIG. 4 , before step 201 , the proximity detection method provided by the embodiment of the present invention may further include the following steps 206 to 207 .

Step 206: The terminal device determines whether the first screen is in a bright screen state, and whether the first screen displays a call interface.

For the method for the terminal device to determine whether the first screen is in a bright screen state, and the method for determining whether the first screen displays a call interface, reference may be made to any related technology, which is not limited in the embodiment of the present invention.

When the terminal device determines that the first screen is in a bright screen state and the first screen displays a call interface, the ultrasonic sensor is turned on; otherwise, the ultrasonic sensor is not turned on.

Step 207: The terminal device turns on the ultrasonic sensor when it is determined that the first screen is in a bright screen state and the first screen displays a call interface.

In this embodiment of the present invention, when the terminal device is not in a bright screen state (that is, in an off screen state), or is in a bright screen state but the call interface is not displayed on the first screen, the terminal device can turn off the ultrasonic sensor, thereby saving power consumption. Moreover, when the first screen is in the bright screen state, it can avoid affecting the display of other contents by the terminal device.

Optionally, the terminal device turns on the infrared sensor when it is determined that the first screen is in an off-screen state and the first screen is not in a call state.

Exemplarily, with reference to FIG. 4 , as shown in FIG. 5 , after step 206 , the proximity detection method provided by the embodiment of the present invention may further include the following steps 208 to 209 .

Step 208: The terminal device turns on the infrared sensor when it is determined that the first screen is in the off-screen state and the first screen is not in the call state.

Step 209: In the case where it is determined according to the infrared sensor that there is an object blocking the first screen within the second preset distance, the terminal device performs at least one of the following: controlling the first screen to remain in an off-screen state, and prohibiting the first screen The preset area is lit when the screen is off, and the preset area is used to display prompt information.

The second preset distance is a distance preset according to an actual use requirement, which is not limited in this embodiment of the present invention.

The second preset distance and the first preset distance may be the same or different, which is not limited in the embodiment of the present invention.

For the method for the terminal device to determine, according to the infrared sensor, that there is a second object within the second preset distance blocking the first screen, reference may be made to any related technology, which is not limited in the embodiment of the present invention.

The prompt information can be clock information, battery information, weather information, fingerprint prompt icon (used to prompt the user for the fingerprint collection area), prompt information of short messages of instant social applications, etc., which can be specifically determined according to actual use requirements. The embodiment of the present invention Not limited.

In the embodiment of the present invention, when the terminal device determines that there is a second object blocking the first screen within the second preset distance according to the infrared sensor, the terminal device controls the first screen to keep the screen off state, which can prevent the first screen from being blocked by an object. When the screen is turned on, the screen is not turned on by the incoming call, or the terminal device lights the screen due to the user's false trigger, thereby reducing power consumption. In the case where the terminal device determines that there is a second object blocking the first screen within the second preset distance according to the infrared sensor, it prohibits the first screen from lighting up a preset area in the off-screen state, and the preset area is used to display prompt information , when there is an object blocking the first screen (indicating that the user does not need to view the prompt information), it is forbidden to display the prompt information in the off-screen state (including the case where the preset area in the current off-screen state is lit and the prompt information is displayed) , cancel the display of the prompt message and turn off the preset area), which can save power consumption. Moreover, through the solution of proximity detection by the infrared sensor in the off-screen state, the accuracy of occlusion detection can be improved without damaging the life of the screen.

In this embodiment of the present invention, the terminal device may also turn on the ultrasonic sensor when it is determined that the first screen is in an off-screen state; and when it is determined according to the ultrasonic sensor that there is an object blocking the first screen within the first preset distance , and perform at least one of the following: controlling the first screen to remain in an off-screen state, and prohibiting the first screen from lighting up a preset area in the off-screen state, where the preset area is used to display prompt information.
