Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

First embodiment

In order to solve the problem that the unlocking manner of the conventional electronic device is complicated, and the service life of the entity key is short due to frequent use of the entity key on the electronic device for unlocking, the present embodiment provides a new unlocking method, please refer to fig. 3, which includes:

s301: and acquiring the current eye related information of the user.

The eye-related information in this embodiment should at least include an angle value of a target included angle between the two eyes of the user and the preset unlocking calibration point on the terminal, where the target included angle is an included angle extending outward from the positions where the two eyes of the user are located and intersecting with the preset unlocking calibration point. It should be noted that the preset unlocking calibration point in this embodiment may be any position point on the terminal, where the position point may be a position point that is specially pre-specified on the terminal screen for unlocking, for example, the position point may be a center position point on the terminal screen, please refer to fig. 4, where fig. 4 is a schematic diagram that the unlocking calibration point 41 is a center point of the mobile phone screen, an included angle X formed by two eyes of the user and the unlocking calibration point is a target included angle, it should be understood that an exact position where the preset unlocking calibration point is located in this embodiment may be set by a developer, and certainly, user self-definition may also be supported.

S302: and unlocking the terminal when the terminal meets the preset unlocking condition according to the eye correlation information and the angle value stored in advance.

For step S302, the obtained angle value of the target included angle may be compared with a prestored angle value, and if equal, it is determined that the terminal satisfies a preset unlocking condition; in some cases, the accuracy of the pre-stored angle value may be fine, for example, the accuracy is as accurate as seconds, so that if the absolute value of the difference between the obtained angle value and the pre-stored angle value is less than or equal to the preset angle threshold value, it may also be determined that the terminal satisfies the preset unlocking condition, and the preset angle threshold value in this embodiment may be flexibly set by a developer according to the actual application scenario of the electronic device, and also supports user-defined.

It should be noted that the angle value pre-stored in this embodiment may be manually input by the user through the touch screen, for example, please refer to fig. 5, the user may input an angle value on the touch screen of the terminal, and after the terminal is locked, the user only needs to adjust the distance between the terminal and the eyes to match the angle value of the target included angle with the previously input angle value, so as to unlock the terminal; in addition, the angle value pre-stored in the terminal may also be entered by the user in a non-manual operation manner, please refer to fig. 6, for example, after the terminal enters the interface for setting the angle value, the user may adjust the distance between the two eyes and the unlocking calibration point, and at this time, the angle value of the current target included angle may be displayed on the display screen of the terminal until the angle value desired by the user is displayed on the display screen of the terminal.

It should be further noted that the preset unlocking condition in step S302 may include any one of a preset screen unlocking condition and a preset application unlocking condition, and therefore, when the preset unlocking condition includes the preset screen unlocking condition, unlocking the terminal in the above steps should include unlocking the screen of the terminal; when the preset unlocking condition includes a preset application program unlocking condition, unlocking the terminal in the above steps should include unlocking the application program on the terminal.

In order to better understand the solution provided by the present invention, the following describes a process of obtaining an angle value of a target included angle.

The terminal can obtain the distances between the two eyes of the user and the unlocking calibration point respectively to obtain a first distance and a second distance, and then the angle value of the target included angle is calculated according to the first distance and the second distance. Specifically, the distances between the two eyes and the sensor can be acquired through the sensor arranged on the terminal, and the sensor in this embodiment may be an infrared sensor, or may be other devices with similar functions. In this embodiment, the infrared sensor may position the positions of the two eyes of the user by using infrared rays with specific wavelengths, so as to obtain the distance between the two eyes and the infrared sensor, if the preset unlocking calibration point is located at the position of the infrared sensor, the distance between the two eyes of the user and the infrared sensor obtained by the infrared sensor is also the first distance and the second distance, of course, if the preset unlocking calibration point is located at another position point on the terminal screen, please refer to fig. 7, which shows the exact position of the unlocking calibration point 41 and the position of the infrared sensor 42, where the exact position is shownHere, the first distance and the second distance may be obtained as follows: the terminal can measure the distances d1 and d2 between the two eyes of the user and the infrared sensor through the infrared sensor, the included angles x1 and x2 between the optical axes corresponding to the two eyes and the plane of the display screen respectively, and can also obtain the distance s between the unlocking calibration point and the position point of the infrared sensor, and the distance between the two eyes of the user and the unlocking calibration point can be obtained by utilizing the cosine theorem of a triangle, and if the first distance is m1 and the second distance is m2, the distance between the two eyes of the user and the unlocking calibration point can be obtained respectively

In this embodiment, after the first distance and the second distance are obtained, various methods may be used to obtain the angle value of the target included angle between the two eyes relative to the unlocking calibration point. Please refer to fig. 8, point Q in fig. 8 is an unlocking calibration point, and the positions of a and B are the positions of eyes, respectively, so that the target included angle is also × AQB, QA is equal to m1, and QB is equal to m2, so to obtain × AQB, only the distance AB or the size of × QAB or × QBA needs to be obtained, and then × AQB can be obtained by adopting the cosine theorem of triangle again.

Therefore, in this embodiment, the angle value of the target included angle can be calculated by measuring the angle of the optical axis corresponding to any one eye relative to the face plane of the user through the infrared sensor, and in addition, the distance between the two eyes of the user can be acquired, so that the angle value of the target included angle is calculated.

In some embodiments, a corresponding relationship table between a face model and a distance between two eyes may be prestored in the terminal system, so when a face is detected, face feature data of a user may be extracted by using a face recognition technology, where the face feature data may include a width, a length, and the like of a face of the user, then a face model that matches the face of the user most closely is matched from the face model prestored in the terminal based on the face feature data, then a distance between two eyes of the user is obtained according to the corresponding relationship table between the face model and the distance between two eyes of the user, and the terminal may calculate an angle value of the target included angle based on the distance between two eyes and the first distance and the second distance.

In some other embodiments, the distance between the two eyes of the user can be obtained by: for example, a three-dimensional coordinate system may be established with the center of the display screen as an origin, the XY coordinate plane is parallel to the display screen, and the direction pointing to the eyes of the user is the Z axis, please refer to fig. 9, it should be noted that, in the specific embodiment, a spatial coordinate system may also be established with other positions as the origin, such as the lower left corner and the upper left corner of the display screen, first, the face of the user may be detected by using the face recognition technology, the positions of the eyes of the user are obtained according to the facial feature data and the coordinate system obtained by the face detection, as shown in the figure, the coordinates of the eyes in the XY plane coordinate system of the coordinate system are respectively obtained according to the data and the coordinate system of the photograph taken by the camera installed on the terminal, and it is assumed that the corresponding coordinate points are (x1, y1) and (x2, y2), generally, when the user performs the unlocking operation on the terminal in practical application, the distance between these two coordinate points can be regarded as the distance between the two eyes of the user, i.e. the distance between the two eyes of the user is

In addition, in order to prevent the terminal from acquiring the eye related information of the user all the time during the use of the terminal, which causes the loss of the electric quantity, the method further comprises the following steps before acquiring the eye related information of the user: and judging whether the sight of the user falls into a preset range, and if so, acquiring the eye related information of the user. The preset range in this embodiment may be set by a developer at will, and in addition, the present embodiment may use an existing gaze tracking algorithm to detect the gaze of the user, which is not described herein again.

When the user unlocks the terminal, the distance between the terminal and the two eyes can be adjusted according to the angle value stored in the terminal before, so that the size of the target included angle is indirectly adjusted, in the process, in order to prompt the user, the user can know the angle value of the current target included angle and move the terminal along the correct direction, and the angle value of the current obtained target included angle can be displayed on a screen of the terminal. Therefore, under the condition that the hands of the user are inconvenient, the terminal can be unlocked through the scheme provided by the invention.

Of course, in some other embodiments, in order to further improve the security of the terminal, the eye-related information may further include eye identification information, and the eye identification information in this embodiment may include at least one of eye pattern information, iris information, and eyeball information. Therefore, the terminal can acquire the eye identification information of the user through the camera while acquiring the angle value of the target included angle or before the step of acquiring the angle value of the target included angle. When the eye-related information includes the eye identification information, determining that the terminal satisfies the preset unlocking condition according to the eye-related information and the pre-stored angle value may include: matching the currently acquired eye identification information with prestored eye identification information, and determining that the terminal meets a preset unlocking condition when the matching is successful and the currently acquired angle value of the target included angle is equal to the prestored angle value; or when the currently acquired eye identification information is successfully matched with the prestored eye identification information and the absolute value of the difference between the currently acquired angle value of the target included angle and the prestored angle value is less than or equal to a preset angle threshold value, determining that the terminal currently meets the preset unlocking condition.

The angle values of the eye recognition information and the target angle stored in advance are explained here. It should be understood that, for the embodiment in which the eye-related information includes the eye identification information, after the user starts the unlocking mode, the user may control the terminal to enter the interface for setting the unlocking password, and after entering the interface, the user's eye identification information and the angle value of the current target included angle are collected by the terminal, and the obtained eye identification information and the obtained angle value are stored as the comparison standard for the subsequent user to unlock the terminal.
