In a first aspect, the present application provides an unlocking method for a terminal device, including: acquiring a relative distance between the terminal device and a target wearable device of the terminal device, wherein the target wearable device is connected with the terminal device and is in a wearing state; acquiring a first included angle between a connecting line between the terminal equipment and the target wearable equipment and the front of the face of a wearing user of the target wearable equipment; acquiring a second included angle between the connecting line and the position right above the head of the wearing user; and unlocking the terminal equipment if the relative distance is within a distance threshold range, the first included angle is within a first equipment included angle threshold range and the second included angle is within a second equipment included angle threshold range.

In the method, the terminal device may be a device capable of performing communication connection. In one example, the terminal device may be a smartphone.

In the method, the target wearable device may be a computer device which is worn and controlled by a user and continuously operates and interacts with the user, and the target wearable device is a device which is in a wearing state and is in communication connection with the terminal device. In one example, the target wearable device may be a headset.

In the method, when the terminal device is unlocked, it is necessary to determine whether a relative distance between the terminal device and a target wearable device of the terminal device is within a distance threshold range, determine whether a first included angle between a connection line between the terminal device and the target wearable device and a position right in front of a face of a wearing user of the target wearable device is within a first device threshold range, and determine whether a second included angle between the connection line and a position right above the head of the wearing user meets a second device included angle threshold range. Compared with the prior art that the distance between the terminal device and the target wearable device is within the range of the preset distance threshold value, the terminal device can be unlocked, and the safety and the reliability are higher.

With reference to the method of the first aspect, in a first possible implementation manner, the obtaining a relative distance between the terminal device and a target wearable device of the terminal device includes: acquiring a first distance between the terminal device and a first reference point on the target wearable device; acquiring a second distance between the terminal device and a second reference point on the target wearable device, wherein the distance difference between the first reference point and the second reference point in the right left direction of the head of the wearing user is greater than 0; accordingly, the relative distance being within a distance threshold comprises: the first distance is within a first device distance threshold range and the second distance is within a second device distance threshold range.

Taking the target wearable device as an earbud headset for example, the first reference point may be disposed on the left headset, which may also be referred to as a left reference point. A second reference point may be provided on the right earpiece, which may also be referred to as a right reference point.

According to the method, the distance from the target wearable device to the terminal device is represented by obtaining the distances from the two reference points to the terminal device, the terminal device can be unlocked only when the distances from the two reference points to the terminal device meet the condition, and the unlocking accuracy can be further improved.

With reference to the first possible implementation manner, in a second possible implementation manner, when a front side of the wearing user is taken as an X-axis, a right left side of the wearing user is taken as a Y-axis, and a right upper side of the wearing user is taken as a Z-axis, a projection length of the first reference point on the Y-axis is equal to a projection length of the second reference point on the Y-axis; accordingly, the first device distance threshold range is the same as the second device distance threshold range.

In the method, the projection length of the first reference point on the Y axis is equal to the projection length of the second reference point on the Y axis, and the first reference point and the second reference point can be symmetrical around the Z axis.

In the method, two reference points are symmetrically arranged, the range of the distance threshold of the first device is the same as that of the distance threshold of the second device, namely, one device distance threshold range can be shared, and the complexity of the scheme is simplified.

With reference to the first or second possible implementation manner, in a third possible implementation manner, the obtaining a first included angle between a connection line between the terminal device and the target wearable device and a position right in front of a face of a user wearing the target wearable device includes: acquiring a ratio of the first distance to the second distance, wherein the ratio is used for representing the first included angle, and the threshold range of the included angle of the first equipment is represented by the threshold range of the ratio; correspondingly, the first included angle being within a first device included angle threshold range includes: the ratio is within a ratio threshold.

In the method, the first included angle is represented by the ratio of the distances from the two reference points to the terminal equipment, the distances from the two reference points to the terminal equipment can be reused without additionally acquiring the first included angle, and the implementation complexity of the scheme can be reduced.

With reference to any one of the first to third possible implementation manners, in a fourth possible implementation manner, the target wearable device includes an earphone device, the earphone device includes a left earphone and a right earphone, and the first reference point and the second reference point are respectively disposed on different earphones of the left earphone and the right earphone.

In some possible implementations, the distance between the terminal device and the user's face may be characterized by the distance between the terminal device and a reference point on the user's face. One example of such a reference point is the tip of the nose.

In some possible implementations, the relative direction between the terminal device and the user's face may be characterized by a first angle between the terminal device and the first reference plane and a second angle between the terminal device and the second reference plane. One example of the first reference plane is as follows: parallel to a plane that can divide the user's head into a left half head and a right half head; an example of the second reference plane is as follows: parallel to a plane that can divide the user's head into upper and lower head halves, or parallel to a plane that can divide the user's head into front and rear head halves.

For example, the first reference plane may be a plane passing through the tip of the nose of the user and dividing the left half head and the right half head of the user. As another example, the second reference plane may be a plane passing through the tip of the nose of the user and dividing the upper half of the head of the user from the lower half of the head. For another example, the second reference plane may be a plane passing through the tip of the nose of the user and dividing the front half head and the rear half head of the user.

An example of the relative distance and relative direction between the terminal device and the user's face is described below in connection with fig. 5.

As shown in fig. 5, the tip of the user's nose is taken as the origin of coordinates, the direction directly above the tip of the nose when the user is upright is taken as the Z-axis, the direction directly in front of the tip of the nose when the user is upright is taken as the X-axis, and the direction directly to the left of the tip of the nose when the user is upright is taken as the Y-axis.

Wherein, the XOZ plane may be used as the first reference plane, the XOY plane may be used as the second reference plane, or the ZOY plane may be used as the second reference plane.

Assuming that the point P represents the position of the terminal device in the coordinate system, the point P is ₁ Indicating the position of the terminal device when mapped onto the XOY plane, point P ₂ Indicating the position of the terminal device when mapped to the XOZ plane.

At this time, the length of the OP is the distance between the terminal device and the face of the user; OP (optical fiber) ₁ Angle theta with positive X-axis direction ₁ The first included angle can be used for representing the relative orientation of the terminal equipment in the left and right directions of the face of the user; OP (optical fiber) ₂ Angle theta with positive Z-axis direction ₂ The second included angle may be used to represent the relative orientation of the terminal device in the up-down direction of the user's face; or, OP ₂ Angle theta with positive X-axis direction ₃ The second angle may be used to represent the relative orientation of the terminal device in the up-down direction of the face of the user.

The length of OP is within a distance threshold range ₁ A first angle between the positive direction of the X axis is within a first angle threshold range OP ₂ A second angle between the positive direction of the Z axisWhen the degree is within the threshold range, the terminal device can be considered to be located in the unlocking range, and the terminal device can be unlocked.

As an example, the distance threshold ranges from 20 centimeters (cm) to 60 cm. As an example, the angle threshold of the first angle ranges from 0 degrees to 45 degrees. As an example, the angle threshold of the second angle ranges from 45 degrees to 135 degrees.

When the distance threshold ranges from 20 cm to 60 cm, the first angle threshold ranges from 0 degree to 45 degrees, and the second angle threshold ranges from 45 degrees to 135 degrees, a terminal unlocking position range according to an embodiment of the present application is schematically illustrated in fig. 6 and 7.

The slant line range shown in fig. 6 is the terminal unlock position range when viewed from the top of the head of the user in a plan view, and the slant line range shown in fig. 7 is the terminal unlock position range when viewed from both sides of the user in a side view.

It will be appreciated that the coordinate system shown in fig. 5 is merely an example. Accordingly, the distance and relative orientation between the user's face and the terminal device determined by the coordinate system are also examples and do not limit the scope of the present application.

When the terminal device is connected with a wearable device and the wearable device is in a wearing state, the distance between the terminal device and the face of the user and the distance between the terminal device and the wearable device are correlated, so that the distance between the terminal device and the face of the user can be represented by the distance between the wearable device which is connected with the terminal device and is in the wearing state and the terminal device.

In the embodiment of the present application, a wearable device connected to a terminal device and in a wearing state may be referred to as a target wearable device of the terminal device.

When the terminal device is connected with a wearable device and the wearable device is in a wearing state, the relative direction between the terminal device and the face of the user and the relative direction between the terminal device and the wearable device are correlated, so that the relative direction between the terminal device and the face of the user can be represented by the relative direction between the wearable device connected with the terminal device and in the wearing state and the terminal device. In embodiments of the present application, the relative direction between the wearable device and the terminal device is also referred to as the relative orientation.

For example, the relative distance and relative orientation between the target wearable device and the user's face may be obtained; then, based on the relative distance and relative orientation, a condition that needs to be satisfied by the relative distance and relative orientation between the user's face and the terminal device when the terminal device can be unlocked is converted into a condition that needs to be satisfied by the relative distance and relative orientation between the target wearable device and the terminal device.

The relative distance between the target wearable device and the terminal device can be represented by the relative distance between a reference point preset on the target wearable device and the terminal device; the relative orientation between the target wearable device and the terminal device can be characterized by the relative orientation between a reference point preset on the target wearable device and the terminal device. The reference point may be one or more, and the embodiment of the present application is not limited to this.

The relative orientation between the reference point preset on the target wearable device and the terminal device may include: the wearable device comprises a first included angle between a connecting line between the terminal device and the target wearable device and a position right in front of the face of a wearing user of the target wearable device, and a second included angle between the connecting line and the position right above the head of the wearing user.

Therefore, as shown in fig. 8, the method for unlocking a terminal device according to an embodiment of the present application may include S810, S820, S830, S840, S850, and S860.

And S810, acquiring the relative distance between the terminal equipment and the target wearable equipment.

S820, a first included angle between a connecting line between the terminal device and the target wearable device and the front of the face of the user wearing the target wearable device is obtained.

And S830, acquiring a second included angle between the connecting line and the position right above the head of the wearing user.

S840, judging whether the relative distance is within the distance threshold range, whether the first included angle is within the first equipment included angle threshold range and whether the second included angle is within the second equipment included angle threshold range.

If the relative distance is within a distance threshold range, the first included angle is within a first device included angle threshold range, and the second included angle is within a second device included angle threshold range, S850 may be performed, otherwise S860 may be performed.

And S850, unlocking the terminal equipment.

And S860, keeping the screen locking state of the terminal equipment.

Taking the target wearable device as an earphone system composed of a left earphone and a right earphone as an example, two reference points may be set on the target wearable device, one of the two reference points is set on the left earphone, and the other is set on the right earphone. Here, the reference point provided on the left headphone may be referred to as a left reference point, and the reference point provided on the right headphone may be referred to as a right reference point.

In this example, as shown in fig. 9, a distance d1 between the left reference point a and the terminal device is acquired, a distance d2 between the right reference point B and the terminal device is acquired, and an included angle α between a line connecting the left reference point and the terminal device and a line connecting the right reference point and the terminal device is acquired ₁ Acquiring an included angle alpha between a connecting line of the terminal equipment and the left reference point A (or the right reference point B) and the reference line ₂ And then based on whether the distance d1 and the distance d2 are within the threshold range of the distance of the device, the included angle alpha ₁ Whether the angle is within the first equipment angle threshold range or not and the included angle alpha ₂ And judging whether the terminal equipment can be unlocked or not by judging whether the terminal equipment is positioned in the second equipment angle threshold range or not. Wherein, the reference line is a straight line parallel to the vertical direction of the user.

The device distance threshold range may be obtained by converting the distance threshold range, the first device angle threshold range may be obtained by converting the first angle threshold range, and the second device angle threshold range may be obtained by converting the second angle threshold range.

As shown in fig. 10, assuming that the straight distance between the two ears of the user is 20 cm, and the distance between the midpoint of the connecting line of the two ears and the tip of the nose is 10 cm, based on the distance threshold range of 20 cm to 60 cm, the first angle threshold range of 0 degrees to 45 degrees, and the second angle threshold range of 45 degrees to 135 degrees, it can be obtained: the device distance threshold range is 24.5 centimeters to 74.1 centimeters, the first device angle threshold range is 0 degrees to 45 degrees, and the second device angle threshold range is 45 degrees to 135 degrees.

That is, if the distance d1 and the distance d2 are in the range of 24.5 cm to 74.1 cm, the included angle α ₁ Within 0 to 45 degrees and an included angle alpha ₂ And within 45-135 degrees, the terminal equipment can be unlocked.

Wherein, when the ratio between the distance d1 and the distance d2 is within the distance ratio threshold, the included angle α is usually included ₁ And the distance d1, the distance d2 and the included angle are obtained, and whether the distance d1 and the distance d2 are in the equipment distance threshold range, whether the ratio of the distance d1 to the distance d2 is in the distance ratio threshold range and the included angle alpha are judged ₂ And judging whether the terminal equipment can be unlocked or not by judging whether the terminal equipment is positioned in the second equipment angle threshold range or not.

For example, when the ratio of the distance d1 to the distance d2 is between 0.72 and 1.39, the included angle α is generally set ₁ Also within 0 to 45 degrees. Thus, if the distance d1 and the distance d2 lie in the range from 24.5 cm to 74.1 cm, the ratio of the distance d1 to the distance d2 lies between 0.72 and 1.39, and the angle α is included ₂ And within 45-135 degrees, the terminal equipment can be unlocked.

In the technical scheme of this application, can obtain the relative distance between terminal equipment and the wearable equipment of target through multiple mode. For example, the relative distance between the terminal device and the target wearable device may be obtained through a Received Signal Strength Indication (RSSI) method, a time of flight (TOF) based method, and a time of arrival (TOA) method.

In the technical scheme of this application, can obtain the relative orientation between terminal equipment and the wearable equipment of target through multiple mode. For example, the relative orientation between the terminal device and the target wearable device may be obtained by an angle of arrival (AOA) method and an angle of departure (AOD) method.

As an example, the terminal device sends a signal to the target wearable device, and the target wearable device receives the signal, and measures the signal strength (or signal transmission duration) of the signal and measures the reception angle of the signal.

Optionally, after the target wearable device measures the signal strength (or the signal transmission duration) and the receiving angle, the target wearable device may obtain a relative distance between the terminal device and the wearable device based on the signal strength (or the signal transmission duration), determine a relative orientation between the terminal device and the wearable device based on the receiving angle, and send the relative distance and the relative orientation to the terminal device; the terminal device receives the relative distance and the relative orientation, and determines whether to unlock based on the relative distance and the relative orientation.

As shown in fig. 11, in S1110, the terminal device transmits a signal to the target wearable device; in S1120, the target wearable device measures a signal strength (or a signal transmission duration) of the received signal and measures a reception angle at which the signal is received, determines a relative distance between the target wearable device and the terminal device based on the signal strength (or the signal transmission duration), and determines a relative orientation between the target wearable device and the terminal device based on the reception angle; in S1130, the target wearable device sends the relative distance and the relative orientation to the terminal device, and accordingly, the terminal device receives the relative distance and the relative orientation; in S1140, the terminal device determines whether to unlock based on the relative distance and the relative orientation.

The unlocking method shown in fig. 11 is further explained by taking an example in which the target wearable device is an earphone system including a left earphone and a right earphone, and a left reference point is provided on the left earphone and a right reference point is provided on the right earphone.

First, the terminal device transmits signals to the left and right earphones, respectively. Then, the left earphone measures the signal strength (or signal transmission duration) of the received signal and measures the receiving angle of the received signal, determines the distance d1 between the left reference point and the terminal device based on the signal strength (or signal transmission duration), and determines the relative orientation between the left reference point and the terminal device based on the receiving angle; and the right earphone measures the signal strength (or signal transmission time length) of the received signal and measures the receiving angle of the received signal, determines the distance d2 between the right reference point and the terminal equipment based on the signal strength (or signal transmission time length), and determines the relative orientation between the right reference point and the terminal equipment based on the receiving angle. Secondly, the left earphone sends the distance d1 between the left reference point and the terminal equipment and the relative orientation between the left reference point and the terminal equipment to the terminal equipment; and the right earphone sends the distance d2 between the right reference point and the terminal equipment and the relative orientation between the right reference point and the terminal equipment to the terminal equipment. Finally, the terminal device determines whether to unlock based on the distance d1, the distance d2, the relative orientation between the left reference point and the terminal device, and the relative orientation between the right reference point and the terminal device.

In this example, the terminal device determining whether to unlock based on the distance d1, the distance d2, the relative orientation between the left reference point and the terminal device, and the relative orientation between the right reference point and the terminal device may include: the terminal equipment judges whether the distance d1 and the distance d2 are located in the equipment distance threshold range or not, judges whether the ratio of the distance d1 to the distance d2 is located in the distance ratio threshold range or not, and judges the included angle alpha according to the relative orientation between the left reference point and the terminal equipment and the relative orientation between the right reference point and the terminal equipment ₂ Whether the device is within a second device angle threshold range; if the distance d1 and the distance d2 are within the range of the distance threshold value of the equipment, the ratio of the distance d1 to the distance d2 is within the range of the distance ratio threshold value, and the included angle alpha is formed ₂ If the device is located in the angle threshold range of the second device, unlocking can be performed; otherwise, unlocking is not possible.

Optionally, after the target wearable device measures the signal strength (or the signal transmission duration) and the receiving angle, the target wearable device may obtain a relative distance between the terminal device and the wearable device based on the signal strength (or the signal transmission duration), determine a relative orientation between the terminal device and the wearable device based on the receiving angle, determine whether to unlock the terminal device based on the relative distance and the relative orientation, and send information indicating that the terminal device is unlocked to the terminal device if the terminal device can be unlocked; the terminal equipment receives the information and unlocks based on the information.

As shown in fig. 12, in S1210, the terminal device transmits a signal to the target wearable device; in S1220, the target wearable device measures a signal strength (or a signal transmission duration) of the received signal and measures a reception angle at which the signal is received, determines a relative distance between the target wearable device and the terminal device based on the signal strength (or the signal transmission duration), determines a relative orientation between the target wearable device and the terminal device based on the reception angle, and determines whether to unlock the terminal device based on the relative distance and the relative orientation; in S1230, the target wearable device sends indication information to the terminal device, where the indication information is used to indicate whether to unlock the terminal device, and accordingly, the terminal device receives the indication information; in S1240, the terminal device determines whether to unlock based on the indication information.

The unlocking method shown in fig. 12 is further described by taking the target wearable device as an earphone system including a left earphone and a right earphone, and taking the left earphone with a left reference point and the right earphone with a right reference point as examples.

First, the terminal device transmits signals to the left and right earphones, respectively. Then, the left earphone measures the signal strength (or signal transmission duration) of the received signal and measures the receiving angle of the received signal, determines the distance d1 between the left reference point and the terminal device based on the signal strength (or signal transmission duration), and determines the relative orientation between the left reference point and the terminal device based on the receiving angle; and the right earphone measures the signal strength (or signal transmission time length) of the received signal and measures the receiving angle of the received signal, determines the distance d2 between the right reference point and the terminal equipment based on the signal strength (or signal transmission time length), and determines the relative orientation between the right reference point and the terminal equipment based on the receiving angle; the left earphone sends a distance d1 and a relative orientation between the left reference point and the terminal equipment to the right earphone, and the right earphone determines whether to unlock the terminal equipment or not based on the distance d1, the distance d2, the relative orientation between the left reference point and the terminal equipment and the relative orientation between the right reference point and the terminal equipment; or the right earphone sends the distance d2 and the relative orientation between the right reference point and the terminal equipment to the left earphone, and the left earphone determines whether to unlock the terminal equipment or not based on the distance d1, the distance d2, the relative orientation between the left reference point and the terminal equipment and the relative orientation between the right reference point and the terminal equipment. Secondly, the left earphone or the right earphone sends indication information to the terminal equipment, the indication information is used for indicating whether the terminal equipment is unlocked or not, and accordingly the terminal equipment receives the indication information. Finally, the terminal equipment judges whether to unlock based on the indication information; and under the condition that the indication information indicates that the terminal equipment is unlocked, the terminal equipment is unlocked.

In this example, determining whether to unlock the terminal device based on the distance d1, the distance d2, the relative orientation between the left reference point and the terminal device, and the relative orientation between the right reference point and the terminal device may include: judging whether the distance d1 and the distance d2 are positioned in the range of the device distance threshold value or not, judging whether the ratio of the distance d1 to the distance d2 is positioned in the range of the distance ratio threshold value or not, and judging the included angle alpha according to the relative orientation between the left reference point and the terminal device and the relative orientation between the right reference point and the terminal device ₂ Whether the device is within a second device angle threshold range; if the distance d1 and the distance d2 are within the range of the distance threshold of the equipment, the ratio of the distance d1 to the distance d2 is within the range of the distance ratio threshold, and the included angle alpha is included ₂ If the terminal equipment is located in the angle threshold range of the second equipment, the terminal equipment can be unlocked; otherwise, the terminal device may not be unlocked.

Optionally, after the target wearable device measures the signal strength (or the signal transmission duration) and the receiving angle, the target wearable device sends the signal strength (or the signal transmission duration) and the receiving angle to the terminal device; the terminal device receives the signal strength (or the signal transmission time length) and the receiving angle, obtains the relative distance between the terminal device and the wearable device based on the signal strength (or the signal transmission time length), determines the relative orientation between the terminal device and the wearable device based on the receiving angle, determines whether to unlock based on the relative distance and the relative orientation, and unlocks if the unlocking is possible.

As shown in fig. 13, in S1310, the terminal device transmits a signal to the target wearable device; in S1320, the target wearable device measures the signal strength (or signal transmission duration) of the received signal and measures the reception angle at which the signal is received; in S1330, the target wearable device transmits the signal strength (or signal transmission duration) and the reception angle to the terminal device, and accordingly, the terminal device receives the signal strength (or signal transmission duration) and the reception angle; s1340, the terminal device determines a relative distance between the target wearable device and the terminal device based on the signal strength (or the signal transmission duration), and determines a relative orientation between the target wearable device and the terminal device based on the receiving angle; in S1350, the terminal determines whether to unlock the terminal device based on the relative distance and the relative orientation.

The unlocking method shown in fig. 13 is further explained by taking an example in which the target wearable device is an earphone system including a left earphone and a right earphone, and a left reference point is provided on the left earphone and a right reference point is provided on the right earphone.

First, the terminal device transmits signals to the left and right earphones, respectively. Then, the left earphone measures the signal strength (or signal transmission duration) of the received signal and measures the receiving angle of the received signal; and the right earphone measures the signal strength (or signal transmission time length) of the received signal and measures the reception angle at which the signal is received. Secondly, the left earphone sends the intensity (or signal transmission duration) of the received signal to the terminal equipment and measures the receiving angle for receiving the signal, and correspondingly, the terminal equipment receives the signal intensity (or signal transmission duration) and the receiving angle; and the right earphone sends the received signal strength (or signal transmission time length) to the terminal equipment and measures the receiving angle for receiving the signal, and accordingly, the terminal equipment receives the signal strength (or signal transmission time length) and the receiving angle. Then, the terminal device determines the distance d1 between the left reference point and the terminal device based on the strength (or signal transmission duration) of the signal sent by the left earphone, and determines the relative orientation between the left reference point and the terminal device based on the receiving angle of the signal; and determining a distance d2 between the right reference point and the terminal device based on the strength (or signal transmission time length) of the signal transmitted by the right earphone, and determining a relative orientation between the right reference point and the terminal device based on the reception angle of the signal. Finally, the terminal device determines whether to unlock based on the distance d1, the distance d2, the relative orientation between the left reference point and the terminal device, and the relative orientation between the right reference point and the terminal device.

In this example, the terminal device determining whether to unlock based on the distance d1, the distance d2, the relative orientation between the left reference point and the terminal device, and the relative orientation between the right reference point and the terminal device may include: the terminal equipment judges whether the distance d1 and the distance d2 are within the equipment distance threshold range or not, judges whether the ratio of the distance d1 to the distance d2 is within the distance ratio threshold range or not, and judges an included angle alpha according to the relative orientation between the left reference point and the terminal equipment and the relative orientation between the right reference point and the terminal equipment ₂ Whether the device is within a second device angle threshold range; if the distance d1 and the distance d2 are within the range of the distance threshold value of the equipment, the ratio of the distance d1 to the distance d2 is within the range of the distance ratio threshold value, and the included angle alpha is formed ₂ If the device is located in the angle threshold range of the second device, unlocking can be performed; otherwise, unlocking is not possible.

As another example, as shown in fig. 14, in S1410, the target wearable device transmits a signal to the terminal device, and the terminal device receives the signal; in S1420, the terminal device measures the signal strength (or signal transmission duration) of the signal and measures the reception angle of the signal; in S1430, the terminal device determines a relative distance between the target wearable device and the terminal device based on the signal strength (or signal transmission duration) of the terminal device, and determines a relative orientation between the target wearable device and the terminal device based on the reception angle; in S1440, the terminal device determines whether to unlock the terminal device based on the relative distance and the relative orientation.

The unlocking method shown in fig. 14 is further explained by taking an example in which the target wearable device is an earphone system including a left earphone and a right earphone, and a left reference point is provided on the left earphone and a right reference point is provided on the right earphone.

First, the left earphone and the right earphone respectively transmit signals to the terminal device, and accordingly, the terminal device receives the signals transmitted by the left earphone and the right earphone. Then, the terminal device measures the intensity (or signal transmission time length) of the signal sent by the left earphone and measures the receiving angle for receiving the signal; and the terminal device measures the intensity (or signal transmission duration) of the signal transmitted by the right earphone and measures the reception angle at which the signal is received. Secondly, the terminal device determines the distance d1 between the left reference point and the terminal device based on the strength (or signal transmission duration) of the signal sent by the left earphone, and determines the relative orientation between the left reference point and the terminal device based on the receiving angle for receiving the signal; and determining a distance d2 between the right reference point and the terminal device based on the strength (or signal transmission time length) of the signal transmitted by the right earphone, and determining a relative orientation between the right reference point and the terminal device based on a reception angle at which the signal is received. Finally, the terminal device determines whether to unlock based on the distance d1, the distance d2, the relative orientation between the left reference point and the terminal device, and the relative orientation between the right reference point and the terminal device.

In this example, the terminal device determining whether to unlock based on the distance d1, the distance d2, the relative orientation between the left reference point and the terminal device, and the relative orientation between the right reference point and the terminal device may include: the terminal equipment judges whether the distance d1 and the distance d2 are located in the equipment distance threshold range or not, judges whether the ratio of the distance d1 to the distance d2 is located in the distance ratio threshold range or not, and judges the included angle alpha according to the relative orientation between the left reference point and the terminal equipment and the relative orientation between the right reference point and the terminal equipment ₂ Whether the device is within a second device angle threshold range; if the distance d1 and the distance d2 are within the range of the distance threshold of the equipment, the ratio of the distance d1 to the distance d2 is within the range of the distance ratio threshold, and the included angle alpha is included ₂ If the device is located in the angle threshold range of the second device, unlocking can be performed; otherwise, unlocking is not possible.

In the technical scheme of the application, under the condition that the relative distance and the relative orientation between the target wearable device and the terminal device both meet the conditions, the unlocking condition of the terminal device also needs to consider the unlocking state of the target wearable device.

In other words, the relative distance and the relative orientation between the target wearable device and the terminal device both satisfy the condition, and the target wearable device is also in the unlocked state, so that the terminal device can be unlocked.

Or in other words, the target wearable device is in the unlocked state, and if the relative distance and the relative orientation between the target wearable device and the terminal device both satisfy the condition, the terminal device may be unlocked.

An exemplary unlocking method of the target wearable device is described below with reference to fig. 15 and 16.

Fig. 15 is a state transition diagram of a target wearable device according to an embodiment of the present application. This embodiment is described taking as an example a target wearable device as an earphone system including a left earphone and a right earphone.

In one example, when the headset is in an unconnected and unworn state, the user wears the headset, and the headset is in an unconnected and worn state.

It can be understood that when the headset detects that the user wears, the headset is detected as a worn state in real time; first indication information is then generated and output to the user, the first indication information indicating that the user has worn the headset.

In a possible implementation manner, when the earphone outputs the first indication information to the user, the first indication information can be output in a voice playing mode.

Alternatively, the output can be performed by flashing a display lamp. The present application is not limited to the manner of blinking the display lamp.

Optionally, after receiving the first indication information, the headset may send the first indication information to the terminal device. Accordingly, after the terminal device receives the first indication information, it can be determined that the user has worn the earphone.

In this embodiment, if the terminal device is in the unlocked state, the terminal device is connected to the headset, and the headset is in the connected and worn state. That is, in the case where the terminal device is in the unlocked state and the earphone is in the connected and worn state, the earphone is in the unlocked state.

Optionally, if the terminal device is in an unlocked state, the terminal device is connected to the headset, the headset is in a connected and worn state, and the terminal device is unlocked once by using biological identification, password or pattern unlocking and the like. That is to say, the terminal device is in the unlocked state, the headset is in the connected and worn state, and the headset is in the unlocked state under the condition that the terminal device is successfully unlocked by means of biometric identification, password or pattern unlocking and the like.

It can be understood that when the headset establishes a connection with the terminal device, communication may be performed through communication methods such as WLAN, bluetooth, and NFC. After the connection between the earphone and the terminal device is established, second indication information may be generated and output to the user, where the second indication information is used to indicate that the earphone and the terminal device are connected.

In a possible implementation manner, when the earphone outputs the second indication information to the user, the second indication information can be output in a voice playing manner.

Alternatively, the output can be performed by flashing a display lamp. It is understood that the manner in which the display lamp flashes when the earphone outputs the second indication information and the first indication information is different.

Optionally, after the earphone is connected to the terminal device, the terminal device may also generate second indication information and output the second indication information to the user. In a possible implementation manner, when the terminal device outputs the second indication information to the user, the second indication information can be output in the form of a display interface.

In another example, the terminal device is connected to the headset when the headset is in an unconnected and unworn state, the headset being in a connected and unworn state.

For the method for establishing the connection between the terminal device and the earphone, reference may be made to the above example, which is not described herein again.

In this embodiment, if the terminal device is in the unlocked state and the user wears the headset, the headset is in the connected and worn state. That is, in the case where the terminal device is in the unlocked state and the earphone is in the connected and worn state, the earphone is in the unlocked state.

In this embodiment, if the terminal device is in the non-unlocked state, and the user wears the headset, the headset is in the connected and worn state, and the terminal device is unlocked by using a biometric identification or password to confirm the identity of the user. That is, the terminal device is in the unlocked state, the headset is in the connected and worn state, and the headset is in the unlocked state when the user identity is confirmed.

The method for determining the wearing state and confirming the identity of the user by the headset may refer to the above example, and will not be described herein.

It can be understood that, when the headset is in the unlocked state, the user disconnects the headset from the terminal device, and the headset is in the worn and unconnected state; after the user takes off the earphone, the earphone is in an unworn state and an unconnected state.

It can be understood that, when the headset is in the unlocked state, and the user takes off the headset, the headset is in the unworn and connected state; and disconnecting the earphone from the terminal equipment by the user, and then putting the earphone in an unworn and unconnected state.

Fig. 16 is a schematic state transition diagram of a target wearable device according to another embodiment of the present application. This embodiment is described taking as an example a target wearable device as an earphone system including a left earphone and a right earphone.

In one example, when the headset is in an unconnected and unworn state, the user wears the headset, and the headset is in an unconnected and worn state; the terminal equipment is connected with the earphone, the earphone is in a connected and worn state, and then the user identity can be detected legally. That is, the headset is in a connected and worn state, and in case the user identity is detected to be legitimate, the headset is in an unlocked state.

In another example, when the headset is in an unconnected and unworn state, the terminal device is connected with the headset, and the headset is in a connected and unworn state; when the user wears the earphone, the earphone is in a connected and worn state, and then the user identity can be detected legally. That is, the headset is in a connected and worn state, and in case the user identity is detected to be legitimate, the headset is in an unlocked state.

In this embodiment, the method for establishing the connection between the terminal device and the earphone and the method for determining the wearing state of the earphone may refer to the method described in fig. 15, which is not described herein again.

In this embodiment, the method for detecting the validity of the user identity may include: when a user wears the earphones, calculating the distance between the left earphone and the right earphone; judging whether the distance between the left earphone and the right earphone is equal to a target distance or not, wherein the target distance is the distance between the left earphone and the right earphone which is acquired when a legal user who records in the earphone wears the earphone; and if the distance between the left earphone and the right earphone is equal to the target distance, the user wearing the earphone is a legal user, and the user identity is successfully confirmed.

In this example, the distance between the left and right earphones may be calculated by a short-range communication technique.

In this embodiment, when the headset is in an unconnected and unworn state, there is no interaction between the headset and the smartphone, and a schematic diagram of a first display interface of the smartphone is shown in fig. 17.

Before the headset establishes a communication connection with the smartphone, the headset sends connection request information to the smartphone, and a schematic diagram of a second display interface of the smartphone may be as shown in fig. 18 (a), where the second display interface includes the connection request information, a first key, and a second key, and is used to determine whether to establish a connection with the headset. In one example, the connection request message is "detect the headset and establish connection", the first button is "yes", and the second button is "no".

Fig. 18 (b) is a schematic diagram of a user clicking a second display interface of a smartphone according to an embodiment of the present application. When the user clicks the first button, the headset and the smart phone start to establish a connection. When the user clicks the second key, the earphone and the smart phone are disconnected.

If the earphone and the smartphone are successfully connected, the smartphone outputs first indication information, where the first indication information is used to indicate that the earphone and the smartphone are successfully connected, and a schematic diagram of the smartphone outputting the first indication information is shown in fig. 19 (a).

If the connection between the earphone and the smart phone fails, the smart phone outputs second indication information, where the second indication information is used to indicate that the connection between the earphone and the smart phone fails, and a schematic diagram of the smart phone outputting the second indication information is shown in fig. 19 (b).

In addition, the earphone can detect whether the user wears the earphone, if the user wears the earphone, third indication information is generated, and the third indication information is used for indicating that the user wears the earphone; and then, the generated third indication information is sent to the smart phone, and accordingly, after the smart phone receives the third indication information, the user is confirmed to wear the earphone.

Optionally, in the case that the connection between the headset and the smartphone is successful, the smartphone may further confirm whether the user has worn the headset through the third display interface. Fig. 20 (a) is a schematic view of a third display interface of a smart phone according to an embodiment of the present application, where the third display interface includes confirmation information, a third button, and a fourth button. In one example, the confirmation message is "please confirm that the headset is worn", the third key is "yes", and the fourth key is "no".

Fig. 20 (b) is a schematic diagram of a user clicking a third display interface of a smartphone according to an embodiment of the present application. And when the user clicks the third key, the user is confirmed to wear the earphone. And when the user clicks the second key, confirming that the user does not wear the earphone.

It can be understood that if the user wears the headset first and then establishes the communication connection between the headset and the smart phone, the smart phone may display the third display interface when the headset and the smart phone are successfully connected.

Optionally, after the user wears the headset and the headset establishes a communication connection with the smartphone, confirmation of the user identity is required. After the user identity is confirmed, the smart phone can further output fourth indication information through a fourth display interface, wherein the fourth indication information is used for indicating that the smart phone can be unlocked through the earphone.
