The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, and the features in the embodiments and the embodiments in the present application can be arbitrarily combined with each other without conflict.

Embodiment 1:

As shown in FIG. 1 , this embodiment provides an alarm method, including the following steps:

Step 101: Set location information indicating that the user uses the mobile terminal in a bad posture; Step 102: In the process of using the mobile terminal, detecting a motion parameter of the mobile terminal, and acquiring, according to the motion parameter, the current current of the mobile terminal Location information;

Step 103: Determine whether the current location information of the mobile terminal matches the set location information, and if yes, go to step 104, if no, go to step 105;

Step 104: The user is considered to use the mobile terminal in a bad posture, and performs a first alarm. Step 105: The user is considered to use the mobile terminal in a normal posture without performing an alarm. The alarm method of the embodiment obtains the current location information of the mobile terminal by using the motion parameter of the mobile terminal, and then determines whether the current location information of the mobile terminal is bad with the set representation of the user. In the posture, the location information of the mobile terminal is matched to determine whether the user is in the bad posture to use the mobile terminal, and if so, the alarm is generated; for example, when the location information includes the screen orientation of the mobile terminal, setting the alarm method of the embodiment may detect the mobile terminal. The current acceleration is used to determine the orientation of the current mobile terminal by acceleration. If the orientation is downward, when the location information indicating that the user uses the mobile terminal in a bad posture is the screen of the mobile terminal facing down, the user is considered to be in a bad posture. When the mobile terminal is used, the user is likely to be in a lying position to use the mobile terminal, so when the user is deemed to be using the mobile terminal in a bad posture, the mobile terminal alerts the user that the user is currently in a bad posture; The alarm method of the example can improve the health of the mobile terminal user. The alarm method of the embodiment indirectly acquires the posture of the user currently using the mobile terminal by detecting the location information of the mobile terminal, and indirectly determines whether the posture of the current user using the mobile terminal is indirectly determined by determining whether the current location information matches the set location information. In the bad posture, the alarm method of this embodiment can quickly determine whether the user is in a posture and promptly alarms.

The location information indicating that the user uses the mobile terminal in a bad posture in the embodiment may be: location information of the mobile terminal when the user uses the mobile terminal in a bad posture. The bad posture of the present embodiment is such that several types of bad postures which are more harmful to the body are compared. For example, it is possible to use a mobile terminal for lying down, a mobile terminal for standing upright, or a bad posture such as using a mobile terminal with the head up. In this embodiment, the location information is corresponding to the user's bad posture; therefore, the location information indicating that the user uses the mobile terminal in the bad posture may be the location information of the mobile terminal when the user uses the mobile terminal in an upright position, and the location information may include : a screen orientation of the mobile terminal and an inclination of the mobile terminal, the inclination angle is an angle between the mobile terminal and a horizontal plane, and the user uses the mobile terminal in an upright position with the screen facing upward and the inclination angle being within a certain range. In this embodiment, the user can set the user's bad posture according to the habit of using the mobile terminal. In this embodiment, the location information is not limited to the orientation and the tilt angle, and may include other location information indicating the gesture, such as the moving speed of the mobile terminal. The position information corresponding to different bad postures in this embodiment is different.

The motion parameters of this embodiment may include: acceleration, velocity, angular velocity, line displacement, angular acceleration, or other parameters related to object motion.

The following describes a process for determining whether the current location information of the mobile terminal matches the set location information:

Setting a screen orientation and tilt that characterizes the user's use of the mobile terminal in a bad posture; Obtaining, according to the motion parameter, a current screen orientation of the mobile terminal and a current tilt angle of the mobile terminal, where the tilt angle is an angle between the mobile terminal and a horizontal plane;

It is judged whether the current screen orientation and inclination of the mobile terminal match the set screen orientation and inclination. If they match, the user is considered to use the mobile terminal in a bad posture and perform the first alarm.

In this case, the alarm method of the present embodiment mainly determines whether the user is in a bad posture by determining the screen orientation and the tilt angle of the mobile terminal, for example, when the screen of the mobile terminal is facing down (the user uses the mobile terminal in a lying posture), At this time, it is determined that the user is in a preset bad posture, and an alarm is issued to alert the user, for example, when the screen of the mobile terminal is facing upward, but the tilt angle is less than a given threshold (such as 45 degrees), indicating that the user uses the mobile phone in the upper body posture. (In this position, the user may cause damage to the neck of the user for a long time), then the user's current posture is judged to be a preset bad posture, and then an alarm is issued to remind the user. Therefore, the process of determining whether the current location information of the mobile terminal matches the set location information in the step 103 of the alarm method in this embodiment includes:

Determining whether the current screen orientation of the mobile terminal is upward, if not, determining that the current location information of the mobile terminal matches the set location information, and if yes, determining whether the current tilt of the mobile terminal is set. Within the range of the tilt angle, if yes, it is determined that the current location information of the mobile terminal matches the set location information.

That is, when the screen of the mobile terminal is facing up and the tilt angle of the mobile terminal is within a preset range, it is considered that the posture of the user currently using the mobile terminal is a bad posture; when the screen of the mobile terminal is facing down And determining that the user's current posture of using the mobile terminal is a bad posture.

Of course, the alarm method of this embodiment does not only determine the user's bad posture by utilizing the orientation and the tilt angle, but also can determine the user's bad posture by using other characteristics of the mobile terminal.

As shown in FIG. 2, the alarm method in this embodiment is specifically described below, including:

Step 201: setting location information indicating that the user uses the mobile terminal in a bad posture; the location information set at this time includes: a tilt range and a screen orientation of the mobile terminal when the user uses the mobile terminal in a bad posture.

Step 202: In the process of using the mobile terminal, detecting a motion parameter of the mobile terminal, and acquiring a screen orientation and a tilt angle of the current mobile terminal according to the motion parameter;

Step 203: Determine whether the screen of the mobile terminal is facing upward, and if yes, perform step 204, if no, Then performing step 205;

Step 204: Determine whether the tilt angle of the mobile terminal is within a preset range, and if yes, execute step 205, if no, perform step 206;

Step 205: It is considered that the current location information of the mobile terminal matches the set location information, and the user uses the mobile terminal in a bad posture, and the mobile terminal performs an alarm;

Step 206: It is considered that the current location information of the mobile terminal does not match the set location information, and the user uses the mobile terminal in the normal posture, and the mobile terminal does not perform an alarm.

The bad postures in the alarm method described in Fig. 2 include: Upright head using the mobile terminal (the screen is facing up and the tilt angle is within a certain range) and lying down using the mobile terminal (screen facing down). The alarm method of this embodiment can issue an alarm when the user operates the mobile terminal in these two postures, reminding the user that the posture is incorrect and cannot be maintained for a long time, thereby improving the health of the user.

In this embodiment, detecting the motion parameter of the mobile terminal may detect the parameter of the mobile terminal by using a sensor. For example, the acceleration of the mobile terminal in three directions of X, Υ, and Ζ axes may be acquired by using a three-axis acceleration sensor; The orientation can be obtained directly by obtaining the positive and negative accelerations of the three-axis acceleration sensor. When the acceleration of the Ζ axis is positive, the screen is facing upwards. When the 加速度 axis acceleration is negative, the screen is facing downward; the inclination can be adjusted by x and y axes. The value is calculated by calculating the corresponding inverse tan trigonometric function value.

As shown in FIG. 3, the alarm method in this embodiment may include the following:

Step 301: After the mobile phone is woken up, the monitoring is started in the background;

Step 302: During the use of the mobile phone, the three-axis acceleration sensor acquires the mobile phone in X, Y,

Acceleration in three directions of the x-axis;

Step 303: determining whether the acceleration in the direction of the x-axis is greater than zero, and if so, executing step 304; if not, executing step 307;

Step 304: determining that the mobile phone screen is facing up, and thinking that the user is in an upright posture at this time;

Step 305: Calculate the tilt angle of the mobile phone according to the acceleration in the X-axis direction, determine whether the tilt angle is greater than the preset threshold a, and if yes, execute step 306, if no, perform step 302; Step 306: Determine the user At this time, I am looking down at the posture of the mobile phone and performing an alarm; Step 307: It is determined that the user is in a posture of lying down using the mobile phone at this time, and an alarm is issued.

The alarm mode of this embodiment includes multiple types of alarms, such as sound, display, and vibration, to alert the user.

The mobile terminal of this embodiment may be a smart phone, a tablet computer, or the like. The sensor in this embodiment may be a sensor originally provided by the mobile terminal, or may be a sensor specially added to the mobile terminal.

Embodiment 2:

As shown in FIG. 4, this embodiment provides an alarm method. The basis of the foregoing Embodiment 1 further includes:

Step 401: During the use of the mobile terminal, detecting a distance between a user's eyes and a screen of the mobile terminal,

Step 402: Determine whether the detected distance is within a preset range, if yes, proceed to step 403, and if not, execute step 404;

Step 403: Perform a second alarm.

Step 404: Keep the mobile terminal working state without performing an alarm.

The alarm method of this embodiment determines whether the user is too close when using the mobile terminal by detecting whether the distance between the user's eyes and the screen of the mobile terminal is within a preset range. If the detected distance is within a preset range, It is considered that the user's eyes are too close to the screen of the mobile terminal, which is likely to cause the user to be near-sighted, so an alarm is issued.

The timing of the processes of steps 401-404 of the present embodiment is not limited, and may be performed before the motion parameters are detected, or after the motion parameters are detected, or may be performed simultaneously with steps 102-103. In summary, steps 401-404 of the present embodiment can be performed before, after or simultaneously with any of the steps in the first embodiment.

The detecting the distance between the user's eyes and the screen of the mobile terminal may include: collecting the image of the user by the camera, and detecting the distance between the user's eyes and the screen of the mobile terminal by using an image processing method. For example, the distance between the eyes of the user is extracted, and the corresponding distance is converted according to physical parameters such as the focal length of the camera.

The alarm method of this embodiment can also immediately alert when the mobile terminal is used when determining that the user is in a bad posture.

The following describes the alarm method in this embodiment in detail. As shown in FIG. 5, the method includes the following steps: Step 501: After the mobile phone is woken up, the monitoring is started in the background;

Step 502: Calculate the distance between the eye and the screen by the method of image processing.

For example, the distance between the eyes of the user is extracted, and the corresponding distance is converted according to physical parameters such as the focal length of the camera.

Step 503: The calculated current distance is compared with the given threshold L. If it is less than L, the process proceeds to step 504. If it is greater than L, the process returns to step 502 to continue monitoring.

Step 504: Determine whether the duration of the distance is greater than the corresponding threshold time T_E. If it is greater, the user is reminded that the distance is too close to the loss of vision. If not, the process returns to step 502 to continue monitoring.

The duration is the time value between the start of the timing and the determination of the current distance being less than the threshold L.

Step 505: Calculate the orientation, inclination, and the like of the screen of the mobile phone by reading the value of the acceleration sensor.

For example, the orientation can directly obtain the positive and negative z-acceleration of the triaxial acceleration sensor; the dip angle can be obtained by calculating the corresponding inverse tan trigonometric function value using the x and y values.

The timing relationship between step 505 and step 502 in this embodiment is not limited, and may include: Step 505 is performed before step 502, step 505 is performed after step 502, or step 505 is performed simultaneously with step 502.

Step 506: It is determined that if the user is facing upward, the user is considered to be in an upright posture, and the angle determination process is entered; if the user is down, the user is considered to be lying down, and the mobile phone is used to enter the corresponding time. Compare Step34.

Step 507: Determine whether the tilt angle of the mobile phone calculated by step 505 is less than the threshold value α. If it is less than, the user is considered to be in a posture of looking down at the mobile phone, and enters the corresponding time comparison; otherwise, the monitoring returns to step 505.

Step 508: Compare whether the duration reaches the reminder time for reading the book Τ-Ν, if yes, go to step 509, if not, continue to monitor and return to step 505.

The duration is the time value between the start of the timing and the time when the inclination is judged to be less than the threshold α. Step 509 reminds the user to pay attention to the activity protection neck push.

Step 510: (Previously, the mobile phone is determined to face downward) to determine whether the duration reaches the T-L time. If yes, proceed to step 511. If not, continue monitoring to return to step 505.

The duration is the time value between the start of the timing and the time when the mobile phone screen is judged to face downward. Step 511: Remind the user to use the mobile phone for a long time to damage the vision.

As shown in FIG. 6, the process of timing in this embodiment includes (taking a mobile phone as an example):

Step 601, detecting that the mobile phone wakes up, that is, when the user starts using the mobile phone, the time starts to enter; step 602, the timer is cleared, and the timing starts;

Step 603: Acquire an absolute speed value of the mobile phone by using a motion sensor.

Step 604, determining whether the absolute speed is greater than the threshold SpeedO; if greater than, it is considered that the user is changing the posture of using the mobile terminal, after changing the posture, returning to step 602, the clearing timer restarts timing; if not greater, the user is considered not to have Changing the gesture using the mobile terminal proceeds to step 605 to continue timing. In the alarm method shown in FIG. 5, the default location information of the user using the mobile terminal in a bad posture is: the screen of the mobile phone is facing up and the tilt angle is less than the threshold value, and the screen of the mobile phone is facing down.

In the alarm method of this embodiment, the sensor can detect the acceleration change amount on the X, Υ, and Ζ axes of the mobile terminal, and then calculate the absolute speed value according to the acceleration changes on the X, Υ, and Ζ axes.
