Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Because long-time lowering head operation intelligent electronic equipment can cause the cervical vertebra to bear huge pressure, consequently this embodiment can calculate cervical vertebra fatigue value according to the user degree of lowering the head that is just head anteversion angle and corresponding duration, and then can remind the user to adjust when necessary and use the gesture, avoids the cervical vertebra to bear huge pressure and causes the influence to healthy. The execution subject is not limited in this embodiment, and for example, the execution subject may be an electronic device such as a terminal (e.g., a mobile phone), a headset (e.g., an earphone, smart glasses), and the like. Of course, a plurality of electronic devices may be combined together to implement the prompting method, for example, the head-mounted device collects the head forward-inclination angle and the corresponding duration, the terminal calculates the cervical vertebra fatigue value, and finally the head-mounted device and/or the terminal outputs the prompting information. Referring to fig. 1 in detail, fig. 1 is a flowchart of a prompting method according to an embodiment of the present invention; the method can comprise the following steps:
s101, acquiring a head anteversion angle and a corresponding duration.
The head forward-tilt angle and the corresponding duration of the acquisition subject are not limited in this embodiment. For example, the head-mounted device may be used, and other electronic devices may be used as long as the head forward-tilt angle and the corresponding duration can be acquired. Of course, the embodiment also does not limit the manner of acquiring the forward inclination angle of the head, for example, when the head-mounted device acquires the forward inclination angle, the forward inclination angle may be acquired by an acquisition device in the head-mounted device, such as an acceleration sensor (e.g., a gravity sensor). When the headset is an earphone, specifically, the forward tilt angle of the head of the user is acquired through a sensor such as gravity built in the earphone (which may be a wired earphone, or a wireless earphone and a headset), and then the corresponding duration is calculated. Further, in order to improve the reliability of acquiring the head anteversion angle and the corresponding duration, when the head anteversion angle is acquired by the head mounted device, it may be confirmed before the acquisition whether the head mounted device is in a state of normal operation, and the step S101 is performed when it is in the state of normal operation. For another example, when the headset is an earphone and the head forward-tilting angle is collected by the gravity sensor, it can be determined whether the earphone is correctly worn before the earphone collects the head forward-tilting angle, and the head forward-tilting angle and the corresponding duration are collected when the earphone is correctly worn.
It is understood that, in order to improve the adaptability of the present embodiment, before executing step S101, it may be determined whether the function of the prompting method provided by the present embodiment is turned on. Only in the case where the function is on, step S101 is executed. The embodiment does not limit the manner of detecting whether the function starts, and for example, may detect whether the flag of the corresponding function is in an on state.
Further, the present embodiment does not limit the manner in which the head anteversion angle and the corresponding duration are acquired. For example, when the execution subject acquiring the head forward-tilt angle coincides with the execution subject acquiring the head forward-tilt angle, the head forward-tilt angle acquired by the acquisition device may be received by a processor in the execution subject, and the processor calculates the corresponding duration. When the execution subject acquiring the head forward-tilt angle is inconsistent with the execution subject acquiring the head forward-tilt angle, the head forward-tilt angle and the corresponding duration time can be transmitted between the two execution subjects in a wireless or wired manner. The head-mounted device acquires, for example, the head forward-tilt angle and the corresponding duration, and transmits the same to the terminal in a wireless manner.
The number of forward-leaning angles of the head is not limited in this embodiment. For example, it may be one head forward inclination angle, but it may also be a plurality of head forward inclination angles, such as all head forward inclination angles collected within a preset time period. The specific correspondence relationship between the head forward inclination angle and the duration is not limited in this embodiment, for example, when the head forward inclination angle is one, the corresponding duration may be the duration of the detected head forward inclination angle, or may be understood as the duration corresponding to the preset angle interval to which the head forward inclination angle belongs. For example, when the head forward-tilt angle is 10 °, the corresponding duration may be 5 seconds for 10 °; it is also possible that the preset angle interval to which 10 ° belongs is (0 °,10 ° ], and the corresponding duration is (0 °,10 ° ] corresponding to a duration of 5 seconds.
When the head forward inclination angle is plural, the corresponding duration may be a duration corresponding to each of the plural head forward inclination angles, or may be a duration corresponding to a preset angle section determined by each head forward inclination angle. For example, when the head forward-tilt angle is 10 °,10 °,10 °,10 °,9 °,9 °, and each angle correspondence time is 1 second, the correspondence time duration may be 4 seconds for 10 ° and 3 seconds for 9 °; it may be that the preset angle interval to which 10 ° belongs is (0 °,10 ° ], and the preset angle interval to which 9 ° belongs is (0 °,10 ° ], and the corresponding duration is (0 °,10 ° ] corresponds to a duration of 7 seconds, and further for example, when the head forward tilt angle is 10 °,10 °,9 °,9 °,9 °,10 °,10 °, 0 °,10 °, and each angle correspondence time is 1 second, the corresponding duration is (0 °,10 ° ] corresponds to a duration of 7 seconds, since 0 ° does not belong to (0 °,10 ° ] this preset angle interval, and therefore even if the total number of angle intervals to which (0 °,10 ° ] belongs is 8 seconds, but the duration thereof is only 7 seconds, it is understood that the duration here refers to the uninterrupted time that continues to accumulate.
In this embodiment, the determination form of the preset angle interval is not limited, for example, the preset angle interval may be determined directly from the value of the head forward-leaning angle, or the preset angle interval may be determined from the difference between the preset normal head angle and the head forward-leaning angle. For example, when the head is tilted forward by 10 degrees, the corresponding predetermined angle range is (0 degrees, 10 degrees), when the predetermined normal head angle is 30 degrees, the difference between the two is 30 degrees minus 10 degrees to 20 degrees, so the corresponding predetermined angle range is a predetermined angle range corresponding to 20 degrees (15 degrees, 25 degrees), in this embodiment, the number of the predetermined angle ranges, the upper and lower limit values of each predetermined angle range and the value of the predetermined normal head angle are not limited, for example, it is found that when the human body is upright, the weight of the cervical vertebrae is the weight of the head, but when the head is inclined, the force applied to the cervical vertebrae is changed, because the weight of the head is constant, the extra weight applied to the cervical vertebrae is all from the tensile force generated by the muscles, when the head is as low as 15 degrees, the pressure applied to the cervical vertebrae is 2 times of the vertical, when the angle reaches 45 degrees, which is 3.7 times that of the vertical. When the angle of the human head is lowered to 60 degrees, the pressure born by the cervical vertebra is 4.5 times of the vertical bearing. Therefore, each preset angle interval, and the upper and lower limit values of each preset angle interval can be set with reference to the result.
In order to improve the efficiency of the subsequent calculation of the cervical vertebra fatigue value. The present embodiment may acquire the head anteversion angle and the corresponding duration in accordance with a preset angle interval. That is, the obtained head forward-leaning angles all belong to the same preset angle interval, and the corresponding duration time is the duration time of the preset angle interval corresponding to the obtained head forward-leaning angle. Preferably, acquiring the head anteversion angle and the corresponding duration may include:
acquiring a head forward inclination angle;
calculating a difference value between a preset normal head angle and a head forward-leaning angle, and determining a preset angle interval to which the difference value belongs;
and counting the dynamic duration corresponding to the difference value in the preset angle interval.
Specifically, since the head forward-inclination angles are collected one by one, when calculating the dynamic duration corresponding to the preset angle interval, it is necessary to first subtract the current head forward-inclination angle from the preset normal head angle to obtain a difference, determine the preset angle interval to which the difference belongs, and start to count the dynamic duration corresponding to the preset angle interval to which the difference belongs. And subsequently, subtracting the head forward inclination angle acquired each time after the preset normal head angle is subtracted in sequence to obtain a difference value, judging whether the difference value belongs to a preset angle interval obtained by initial calculation, if so, increasing the dynamic duration corresponding to the preset angle interval, and if not, taking the dynamic duration corresponding to the preset angle interval obtained last time as the final dynamic duration corresponding to the preset angle interval. For example, when the head forward inclination angle is 10 °, and the preset normal head angle is 30 °, the corresponding difference is 20 °, the preset angle interval to which 20 ° belongs is (15 °,25 ° ], and at this time, the dynamic duration time corresponding to (15 °,25 ° ] is 1 second, and the head forward inclination angle acquired thereafter is also subjected to the above-mentioned processing, and if the head forward inclination angle acquired thereafter is 10 °,9 °,9 °,10 °,10 °, 0 °, it is determined that only the difference 30 ° corresponding to 0 ° does not belong to the preset angle interval (15 °,25 ° ]), the difference values corresponding to the forward inclination angles of the head before 0 ° all belong to (15 °,25 °), and therefore the dynamic duration corresponding to the corresponding difference values at (15 °,25 °) is 7 seconds.
And S102, calculating a cervical vertebra fatigue value according to the head forward-leaning angle and the duration.
It is understood that, since the number of the head forward-leaning angles in step S101 is not limited, the embodiment does not limit the corresponding manner of calculating the cervical vertebra fatigue value according to the head forward-leaning angles and the duration. The cervical vertebra fatigue value can be obtained by firstly calculating the currently acquired head forward inclination angle and the duration to obtain the cervical vertebra fatigue increase value, and then combining the cervical vertebra fatigue accumulation value obtained before to finally obtain the cervical vertebra fatigue value. Or directly calculating the currently acquired head anteversion angle and duration together with the historically accumulated head anteversion angle and corresponding duration to obtain the cervical vertebra fatigue value. In order to improve the calculation efficiency in this embodiment, only the increment may be calculated each time, that is, preferably, according to the head forward-inclination angle and the duration, the calculating of the cervical vertebra fatigue value may include:
calculating the fatigue increase value of the cervical vertebra according to the forward inclination angle and the duration of the head;
and adding the cervical vertebra fatigue accumulation value and the cervical vertebra fatigue increase value to obtain a cervical vertebra fatigue value.
The head forward-leaning angle corresponding to the cervical vertebra fatigue increasing value is obtained after the cervical vertebra fatigue value (namely the cervical vertebra fatigue accumulated value) is calculated last time. Specifically, the embodiment does not limit the specific way of calculating the cervical vertebra fatigue increase value according to the head forward inclination angle and the duration. For example, when the head forward-inclination angle is only one in step S101, the cervical vertebra fatigue increase value can be determined directly according to the head forward-inclination angle and the value of the duration. For example, when the head forward-tilting angle is 10 ° and the corresponding duration is 1 second, the corresponding cervical vertebra fatigue increase value is 10. When the head forward-leaning angle is 10 ° and the corresponding duration is 3 seconds, the corresponding cervical vertebra fatigue increase value is 30. Or a corresponding fatigue weight value can be set for each head forward-leaning angle, and the cervical vertebra fatigue increase value is calculated by using the fatigue weight value and the duration. For example, the two are multiplied to obtain the cervical vertebra fatigue increasing value. For example, when the head forward-tilt angle is 10 °, the corresponding fatigue weight value is 2, and the duration is 3 seconds, the corresponding cervical vertebra fatigue increase value is 6. Of course, it may also be determined whether the head is in an abnormal posture directly according to the value of the head forward-tilting angle, and then it may be determined whether the user needs to be reminded to adjust the posture directly according to the duration time. For example, each head forward tilt angle corresponds to a maximum duration, and when the user exceeds the maximum duration in the head forward tilt angle, it is determined that the posture adjustment prompt message needs to be output.
When the head forward-inclination angle is plural in step S101, the total cervical vertebra fatigue increase value can be calculated by calculating each head forward-inclination angle of the plural head forward-inclination angles in the above-mentioned various manners. Certainly, the cervical vertebra fatigue increase value may also be calculated according to the fatigue weight values and the durations of the preset angle intervals corresponding to the multiple head forward-leaning angles. For example, when the collected head forward inclination angle is 10 °,9 °,9 °,9 °,10 °, and 10 °, the corresponding preset angle interval is (15 °,25 ° ], the fatigue weight value corresponding to (15 °,25 ° ] is 5, and the corresponding duration is 6, the corresponding cervical vertebra fatigue increase value is 30.
In order to further improve the efficiency of calculating the fatigue increasing value of the cervical vertebra. In this embodiment, calculating the fatigue increase value of the cervical vertebra according to the forward-leaning angle and the duration of the head may include:
determining a corresponding fatigue weight value according to the head forward-leaning angle;
and multiplying the fatigue weight value by the duration to obtain the cervical vertebra fatigue increasing value.
Specifically, the manner of determining the corresponding fatigue weight value according to the head forward-inclination angle is not limited in this embodiment, and each head forward-inclination angle may correspond to one fatigue weight value, or of course, a plurality of head forward-inclination angles may correspond to one preset angle interval, and each preset angle interval corresponds to one fatigue weight value. At this time, determining the corresponding fatigue weight value according to the head forward-leaning angle may include:
calculating the difference value between the preset normal head angle and the head forward-leaning angle;
and acquiring a fatigue weight value corresponding to the preset angle interval to which the difference value belongs.
In this embodiment, a specific value of the fatigue weight value corresponding to each preset angle interval is not limited. The manner of obtaining the preset normal head angle is not limited. Referring to fig. 2, when the forward tilt angle of the head is collected by a gravity sensor in the earphone, the present embodiment provides an obtaining method of presetting a normal head angle. Prompting a user to wear the earphone in a correct upright posture, and recording an included angle between the earphone handle and the gravity direction when the user wears the earphone in the correct upright posture, wherein the included angle is a preset normal head angle. Certainly, in order to avoid errors, the precision of the preset normal head angle is improved, and in this embodiment, the user may be prompted to repeatedly execute the above process for multiple times, and then the average value is taken to obtain the preset normal head angle. The present embodiment does not limit the number of times the user repeatedly performs. The preset normal head angle is 30 deg. as in fig. 2.
And S103, outputting posture adjustment prompt information when the cervical vertebra fatigue value exceeds a preset alarm threshold value.
In this embodiment, the specific value of the preset alarm threshold is not limited. The user can set and modify according to the actual situation. Such as 300. In this embodiment, a specific manner of outputting the posture adjustment prompt information is not limited. For example, the sound output may be a voice output, a vibration output, an indicator light output, or a specific sound output (such as a buzzer, a specific music, a prolonged sound, etc.). Of course any combination thereof is possible. The corresponding embodiment also does not limit the number of times of outputting the posture adjustment prompt information, for example, the posture adjustment prompt information may be output once, or may be output as long as the cervical vertebra fatigue value obtained through the circular calculation exceeds the preset alarm threshold value, and when the cervical vertebra fatigue value continuously exceeds the preset alarm threshold value, the posture adjustment prompt information is output in a circular manner. When the output form is a voice output, the present embodiment does not limit the specific contents of the voice output. As long as it can play a role in reminding the user of the posture adjustment. For example, the fatigue degree of the cervical vertebra of the user can be included, or a suggested posture adjustment mode is included on the basis of the fatigue degree, and the like.
In order to further improve the applicability of the embodiment, the requirement of a user for using the prompting method under various scenes is met. In this embodiment, a specific manner in which the user cancels the output prompt this time or cancels the output prompt function is not limited. Specifically, when a preset event for canceling the prompt is detected, the cervical vertebra fatigue accumulation value is cleared, and the output of posture adjustment prompt information is stopped. At this time, not only the output of the posture adjustment prompt information is stopped, but also the cervical vertebra fatigue accumulation value is cleared when the cervical vertebra fatigue accumulation value exists, so that the step S101 can be executed in the initial state, and the next calculation process is started.
The preset event is not limited in this embodiment. For example, the preset event can be detected by collecting specific voice information; if the collection: i know that voice information for cheerful stop prompting is used as a preset event. The preset event may also be detected by detecting whether a user tapping information is detected after the posture adjustment prompt information is output, for example, when the execution main body is an earphone, the earphone detects the preset event by detecting whether a user tapping signal is received. Or detecting a preset event by receiving an instruction to stop outputting; if the specific data information is received, the user needs to stop outputting the posture adjustment prompt information. Of course, the preset event may be detected by detecting that the user has recovered to a normal posture of the cervical vertebrae. The determination method for recovering the normal posture of the cervical vertebrae is not limited in this embodiment. For example, the user may maintain a normal cervical posture for a preset time threshold. The preset event may be detected by detecting a forward tilt angle of the head of the user as a preset normal angle interval. Preferably, the preset event is detected by judging that the duration corresponding to the acquired head forward-leaning angle belonging to the preset normal angle interval exceeds a preset time threshold. The present embodiment does not limit the specific value of the preset time threshold, and may be 30 seconds, for example. Specifically, the fatigue accumulation value of the cervical vertebra can be cleared after the duration of the preset normal angle interval of the head of the user exceeds 30 seconds, and the output of the posture adjustment prompt message is stopped.
The embodiment does not limit the specific execution action when the cervical vertebra fatigue value does not exceed the preset alarm threshold, and for example, the procedure may be directly executed to step S101 for the next calculation process. Step S101 may be executed after the cervical vertebra fatigue value calculated in step S102 is set as a new cervical vertebra fatigue accumulation value.
Based on the technical scheme, the prompting method provided by the embodiment of the invention can calculate the cervical vertebra fatigue value through the acquired head forward-leaning angle and duration, and further can judge whether the pressure borne by the cervical vertebra of the user is normal or not according to the cervical vertebra fatigue value, so that the prompting information can be output when necessary to remind the user to adjust the using posture in time, and the influence on the body health caused by the huge pressure borne by the cervical vertebra is avoided.
Based on the above embodiments, the present embodiment is to further improve the calculation efficiency in the prompting process. In this embodiment, the counting the dynamic duration corresponding to the difference value in the preset angle interval may include:
counting the dynamic duration time of the difference value corresponding to the preset angle interval, and judging whether the dynamic duration time exceeds an alarm time threshold value corresponding to the preset angle interval in real time;
if yes, directly outputting attitude adjustment prompt information;
if not, go to step S102.
In this embodiment, while the dynamic duration is counted, whether the current counted dynamic duration exceeds the alarm time threshold corresponding to the preset angle interval is determined in real time. If the output value exceeds the preset value, the posture adjustment prompt information is directly output, and subsequent steps, namely step S102 and step S103, do not need to be executed. And further, the subsequent calculation amount is reduced, and the calculation efficiency is improved. Since the cervical vertebra fatigue increasing value needs to be added to the cervical vertebra fatigue accumulated value when calculating the cervical vertebra fatigue value in step S102. At the moment, the dynamic duration time exceeds the corresponding alarm time threshold value, so that the fact that the current cervical vertebra fatigue increase value exceeds the preset alarm threshold value is proved, and the posture adjustment prompt information can be determined to be output without increasing the cervical vertebra fatigue accumulation value. So that no subsequent operation needs to be performed. Although the specific value of the alarm time threshold corresponding to the preset angle interval is not limited in this embodiment, the alarm time threshold may be a dynamic duration value correspondingly required by the preset angle interval when the preset alarm threshold is obtained through calculation. For example, when the preset alarm threshold is 300 and the fatigue weight value of a certain preset angle interval is 5, the fatigue weight value is multiplied by the dynamic duration to obtain the cervical vertebra fatigue increase value, and the cervical vertebra fatigue increase value is the preset alarm threshold, that is, 300. The corresponding dynamic duration is 300/5 ═ 60 seconds.
Based on the technical scheme, the prompting method provided by the embodiment of the invention can calculate the cervical vertebra fatigue value through the acquired head forward-leaning angle and duration, and further can judge whether the pressure borne by the cervical vertebra of the user is normal or not according to the cervical vertebra fatigue value, so that the prompting information can be output when necessary to remind the user to adjust the using posture in time, and the influence on the body health caused by the huge pressure borne by the cervical vertebra is avoided. And the calculation efficiency in the prompting process is improved by judging the size of the alarm time threshold corresponding to the dynamic duration and the preset angle interval in real time.
Based on any of the above embodiments, when the head forward-tilt angle is collected by the head-mounted device, this embodiment may further include:
when the head forward-leaning angle belongs to a preset abnormal angle interval, outputting prompt information that the head-mounted equipment is not normally worn.
Specifically, when the collected head forward-leaning angle belongs to a preset abnormal angle interval, it is indicated that the user cannot normally wear the head-mounted device, and therefore, the user needs to be prompted to normally wear the head-mounted device in time for smooth proceeding of a subsequent process. Of course, the specific manner of outputting the prompt information that the head-mounted device is not normally worn is not limited in this embodiment. For example, the sound output may be a voice output, a vibration output, an indicator light output, or a specific sound output (such as a buzzer, a specific music, a prolonged sound, etc.). Of course any combination thereof is possible. The corresponding embodiment also does not limit the number of times of outputting the prompt information that the head-mounted device is not normally worn, and for example, the prompt information may be output once, or may be output as long as the user does not normally wear the head-mounted device. When the output form is a voice output, the present embodiment does not limit the specific contents of the voice output. As long as the user can be reminded to normally wear the head-mounted device.
Further, in order to prevent the accidental situation that the head forward-tilting angle belongs to the preset abnormal angle interval, the present embodiment may also limit the duration that the head forward-tilting angle belongs to the preset abnormal angle interval, for example, when the user continues to belong to the preset abnormal angle interval for 5 seconds, it is proved that the head-mounted device is not worn normally. The embodiment does not limit the specific value of the duration time belonging to the preset abnormal angle interval, and the user can set the duration time according to the actual situation.
Based on the technical scheme, the prompting method provided by the embodiment of the invention can calculate the cervical vertebra fatigue value through the acquired head forward-leaning angle and duration, and further can judge whether the pressure borne by the cervical vertebra of the user is normal or not according to the cervical vertebra fatigue value, so that the prompting information can be output when necessary to remind the user to adjust the using posture in time, and the influence on the body health caused by the huge pressure borne by the cervical vertebra is avoided. Whether the head-mounted equipment is normally worn or not is judged by detecting whether the head forward inclination angle belongs to a preset abnormal angle interval or not, and then the reliability of the subsequent calculation process is ensured.
