Fig. 3 is a flowchart illustrating a human body posture reminding method according to another exemplary embodiment, which is applied to an intelligent terminal, and which includes the following steps as shown in fig. 3.
In step 301, a first angle of the smart terminal with respect to the ground is obtained while the user views the smart terminal.
In this embodiment, the smart device may acquire the first angle when the user starts to use the smart terminal, that is, acquire the first angle when the user lights up the screen.
When the first angle is obtained, sensing devices such as a gyroscope and an acceleration sensor are arranged in the intelligent terminal, and the intelligent terminal can calculate the first angle according to at least one of the gyroscope and the acceleration sensor, which is not described herein.
It should be noted that, the attitude of the intelligent terminal in the air is three-dimensional, and in this embodiment, an angle of the intelligent terminal relative to the vertical direction may be taken, and the angle is used as a first angle of the intelligent terminal relative to the ground.
In step 302, a second angle of the face relative to the intelligent terminal is obtained.
The method comprises the following two substeps of:
in sub-step 3021, a face image of a face is acquired by a front-facing camera in the intelligent terminal.
The intelligent terminal can control the front-facing camera to shoot when the user looks at the intelligent terminal, and the picture shot by the front-facing camera contains a face image because the user needs the face to face the intelligent terminal when looking at the intelligent terminal.
The shooting is not performed by pressing the shooting button by the user, but is performed directly without the user's operation, so as to avoid disturbing the user. In addition, the face image is used for the intelligent terminal to calculate the second angle, which is not useful for the user, so the intelligent terminal can delete the face image after calculating the second angle and does not store the face image in the intelligent terminal, thereby saving the storage space of the intelligent terminal.
In sub-step 3022, a second angle of the face with respect to the intelligent terminal is determined from the face image.
There are many algorithms for the intelligent terminal to calculate the second angle, and this embodiment is exemplified by one of them.
The intelligent terminal acquires a three-dimensional face model of a user and each characteristic point on a face image; setting a three-dimensional model of a human face to be positioned at an initial position; rotating the three-dimensional model of the human face until the two-dimensional projection of the three-dimensional feature points on the three-dimensional model of the human face is overlapped with the feature points on the human face image as much as possible; and calculating a second angle according to the initial position and the angle rotated by the three-dimensional model of the face. The feature points may be pixel positions of eyes, nose, mouth, etc.
When the three-dimensional model of the human face is rotated, 3 parameters can be defined, namely an up-down rotation angle represented by pitch, a left-right rotation angle represented by yaw and an in-plane rotation angle represented by roll. Referring to fig. 4 and 5, fig. 4 shows a three-dimensional model of a face, and fig. 5 shows three rotation modes of the three-dimensional model of a face.
It should be noted that, the pose of the face in the air is three-dimensional, and in this embodiment, the angle of the face in the vertical direction relative to the intelligent terminal may be taken as the second angle of the face relative to the intelligent terminal.
It should be noted that, the intelligent terminal may acquire the first angle first and then acquire the second angle; or the second angle can be acquired first and then the first angle can be acquired; the first angle and the second angle may also be acquired simultaneously, and the sequence of execution of steps 301 and 302 is not limited in this embodiment.
In step 303, the angle of the face relative to the ground is obtained according to the first angle and the second angle.
Assuming that the first angle is 70 degrees, if the face rotates upwards relative to the intelligent terminal and the rotation angle is 10 degrees, the angle of the face relative to the ground is=70+10=80 degrees; if the face rotates downward relative to the intelligent terminal and the rotation angle is 10 degrees, the angle of the face relative to the ground is=70-10=60 degrees.
In step 304, the weight carried by the user's spine is obtained from the angle.
The intelligent terminal can acquire the corresponding relation shown in fig. 1, and find the weight corresponding to the angle in the corresponding relation.
In step 305, the length of time the spine is subjected to the weight is obtained.
If the user keeps a posture unchanged when looking at the intelligent terminal, the weight born by the vertebra is unchanged, and at the moment, the intelligent terminal needs to acquire the duration of the weight born by the vertebra; if the user changes the posture while viewing the smart terminal, the spine bears various weights, at which time the smart terminal needs to acquire the length of time the spine bears each weight.
The method comprises the following three substeps of:
in sub-step 3051, the weight borne by the vertebra is acquired at predetermined time intervals.
The duration of the predetermined time interval may be an experimental value or an empirical value, or may be calculated according to a predetermined algorithm, which is not limited in this embodiment.
In one possible implementation, the predetermined time interval may be 30 seconds.
When the intelligent terminal acquires one weight born by the vertebra for the first time, the length of time for the vertebra to bear the weight is 0; when the intelligent terminal does not acquire the weight born by the vertebra for the first time, step 3052 or 3053 is performed.
In sub-step 3052, when the current weight acquired is the same as the previous weight acquired, the length of time the vertebra is subjected to the weight is updated according to the predetermined time interval.
For example, when the weight obtained by the intelligent terminal for the fourth time is the same as the weight obtained by the intelligent terminal for the third time, determining that the duration of bearing the weight by the vertebra is the duration of three preset time intervals; when the weight obtained by the intelligent terminal for the fifth time is the same as the weight obtained by the intelligent terminal for the fourth time, determining that the duration of the vertebra bearing the weight is the duration of four preset time intervals, and so on.
In sub-step 3053, when the weight acquired this time is different from the weight acquired last time, the duration of the vertebra bearing the weight acquired last time is kept unchanged, and the duration of the vertebra bearing the weight acquired this time is updated according to a predetermined time interval.
For example, when the weight obtained by the intelligent terminal for the fifth time is different from the weight obtained by the intelligent terminal for the previous time, determining that the duration of the vertebra bearing the weight obtained by the previous time is the duration calculated when the weight is obtained for the fourth time, namely, the duration of three preset time intervals; the length of time that the vertebra bears the weight acquired this time is the length of a preset time interval.
In step 306, a reminder weight is calculated based on the weight and the duration.
When a weight exists, calculating a reminding weight according to the weight and the duration, wherein the method comprises the following steps: and multiplying the weight by the time length to obtain a reminding weight. When at least two weights exist, calculating a reminding weight according to the weights and the time length, wherein the method comprises the following steps: and multiplying each weight by the time corresponding to the weight, and adding the obtained products to obtain the reminding weight.
In step 307, it is detected whether the alert weight exceeds a first threshold.
The first threshold may be an experimental value or an empirical value, or may be calculated according to a predetermined algorithm, which is not limited in this embodiment.
When the alert weight exceeds the first threshold, step 308 is performed; when the alert weight does not exceed the first threshold, step 301 is continued.
In step 308, when the alert weight exceeds the first threshold, the user is alerted.
In this embodiment, the intelligent terminal may remind the terminal in any form, for example, a voice prompt, a popup prompt, a bell sound prompt, a vibration prompt, a flashing prompt of an indicator light, a status bar prompt, and the like, which is not limited in this embodiment. In addition to setting the reminding mode, the intelligent terminal can set the reminding duration, and the embodiment is not limited.
The intelligent terminal can also determine a reminding mode according to the application type of the application being checked by the user, so that the reminding mode with the least influence on the user is selected when the user does not want to be disturbed, and the disturbance on the user is avoided; and when the user can be disturbed, a reminding mode with the best reminding effect is selected so as to ensure the reminding effect. At this time, the user is reminded, which includes the following three sub-steps:
in sub-step 3081, the application type of the application currently running in the foreground in the intelligent terminal is obtained.
The intelligent terminal is pre-stored with the corresponding relation between the application and the application type. For example, the application types may include a disturbed-disabled type and a disturbed-allowed type, and the game application and the video application belong to the disturbed-disabled type and the electronic book application belongs to the disturbed-allowed type. Of course, the intelligent terminal may also set other application types, which is not limited in this embodiment.
In sub-step 3082, a reminder for the user is determined based on the application type.
The intelligent terminal can preset the corresponding relation between the application type and the reminding mode, for example, the disturbed type is forbidden to correspond to the reminding mode of vibration reminding, and the disturbed type is allowed to correspond to the reminding mode of popup reminding.
If the application currently running in the foreground is a game application, the intelligent terminal determines that the reminding mode is vibration reminding; if the application currently running in the foreground is an electronic book application, the intelligent terminal determines that the reminding mode is popup reminding.
In substep 3083, the user is alerted in an alert manner.
Referring to fig. 6, a schematic diagram of a human body posture after reminding is shown, wherein a left side view is the human body posture of a user before reminding, and a right side view is the human body posture of the user after reminding.
After reminding the user, the intelligent device clears the reminding weight immediately, and step 301 is executed again. Or after reminding the user, the intelligent device clears the reminding weight value after waiting for a period of time, and step 301 is executed again. Or the intelligent terminal can calculate the change weight, and gradually counteract the reminding weight by using the change weight when the human body posture is standard, namely, the reminding weight is reduced when the human body posture is standard; when the human body posture is not standard, the reminding weight is gradually increased by utilizing the change weight, so that the fatigue degree of the cervical vertebra is reflected by the reminding weight, and the accuracy of the reminding weight is improved.
In step 309, after alerting the user, the weight of the user's spine is again acquired.
The process of acquiring the weight born by the vertebra is the same as that of steps 301-304, and will not be described here.
In step 310, a variation weight is calculated based on the weight and the length of time the spine is subjected to the weight.
The flow of calculating the offset weight is the same as the flow of calculating the reminding weight, and will not be described here.
The intelligent terminal compares the acquired weight with a second threshold value, and when the weight exceeds the second threshold value, the intelligent terminal is determined to calculate an increased change weight; when the weight does not exceed the second threshold, it is determined that the intelligent terminal calculates a reduced change weight. The second threshold may be an experimental value or an empirical value, or may be calculated according to a predetermined algorithm, which is not limited in this embodiment.
In step 311, when the weight does not exceed the second threshold, the reminding weight is updated by using the difference of the reminding weight minus the change weight.
In step 312, when the weight exceeds the second threshold, the alert weight is updated with the sum of the alert weight plus the change weight.
In summary, according to the human body posture reminding method provided by the disclosure, by acquiring the angle of the face of the user relative to the ground, the weight born by the spine of the user can be acquired according to the angle, and then the length of the spine bearing the weight is acquired, so that the user is reminded according to the weight and the length of the spine, when the spine of the user bears the weight for a long time, the user is reminded to adjust and view the human body posture of the intelligent terminal, the problem that the user is reminded to walk when the user sits for a long time by the wearable device, if the user still bears the weight when walking, cervical vertebra fatigue can be caused is solved, and the effect of protecting the cervical vertebra is achieved.
The reminding mode is determined according to the application type of the application which is being checked by the user, so that the reminding mode with the least influence on the user is selected when the user does not want to be disturbed, and the disturbance on the user is avoided; and when the user can be disturbed, a reminding mode with the best reminding effect is selected so as to ensure the reminding effect.
The change weight is calculated, and when the human body posture is standard, the change weight is utilized to gradually offset the reminding weight, namely the reminding weight is reduced when the human body posture is standard; when the human body posture is not standard, the reminding weight is gradually increased by utilizing the change weight, so that the fatigue degree of the cervical vertebra is reflected by the reminding weight, and the accuracy of the reminding weight is improved.
