Embodiment
Below in conjunction with accompanying drawing, the better embodiment of correcting sitting posture method is described.
When abnormal sitting posture is true, the health certain angle that conventionally can tilt above the waist, head also can tilt thereupon.Conventionally can come reminding user to correct faulty sitting posture in time by detecting head to the distance between target observation thing (as books), or come reminding user to correct faulty sitting posture in time by detecting head tilt fore and aft degree.
In reality, find, even if head does not tilt forward and back, and head to the distance of books is greater than standard value, but head is if tilt, and is also a kind of incorrect sitting posture.Now head does not tilt forward and back, even if be provided with, detects the yet therefore warning of device that tilts forward and back angle; If borrow head to the distance between target observation thing detect whether to meet standard value to judge and only rely on, because the distance now detecting is greater than standard value, therefore reminding user corrects faulty sitting posture in time.Correcting sitting posture problem while tilting in order also to solve head, the invention provides following examples.
Fig. 1 is the process flow diagram of the correcting sitting posture method of an embodiment, is particularly useful for the rectification of sitting posture of student, below in conjunction with concrete steps, describes in detail.
S110, human body eyes are to the distance S of target observation thing.In reality, can utilize the distance measuring equipments such as ultrasonic sensor that are fixed on human body head to measure human eye to the distance S of target observation thing.
S120, the human body head angle [alpha] that tilts.The angle [alpha] that tilts while utilizing obliquity sensor detection head to tilt.As shown in Figure 2, this angle [alpha] that tilts is head while tilting, and the angle between inclination front and back position, is an angle in vertical plane.It can be the angle that normal sitting position position is tilted to the left or is tilted to the right and forms.
S130, described S and preset data are compared, when S is greater than described preset data, according to the described angle [alpha] that tilts, calculate the cosine value of S, and the cosine value of described S and preset data are compared.Preset data is standard value (set think safe distance or the ideal distance not affecting one's power of vision).
When human body is during in standard sitting posture, the distance of human body distance objective observation thing equals standard value.Now, when if human body does not tilt forward and back and integral body moves forward and backward, the certain angle α but human body head tilts, the human eye who detects will be greater than preset data to the distance S of target observation thing, now only rely on this apart from S, cannot give prompting of user, because report to the police and carry out when this distance is less than preset data to user's prompting by judging distance.But obvious now human body is in a wrong sitting posture.Therefore the situation of, utilizing obliquity sensor to tilt to correct human body head herein.And if S is less than preset data, illustrate that now eyes target observation thing distance is nearer, can directly to user, send corresponding prompting and report to the police, with effective vision protection.
Please refer to Fig. 2, after tilting apart from S representative, eyes are to the distance of target observation thing.Because S cannot directly be used for correcting faulty sitting posture, and during human normal sitting posture, human body, to forming a vertical plane X between target observation thing, is drawn a reference distance S thus in Fig. 2
real, can be regarded as S
realfor the projector distance in plane X apart from S.In Fig. 2, the corresponding line segment of S, S
realcorresponding another line segment, the value of the angle forming in level between two line segments is approximately equal to the aforesaid angle [alpha] that tilts in vertical plane.Therefore, can use the cosine value of S as the approximate value of S reality.By formula S
real=S * COS α, calculates the cosine value of S, i.e. S in real time according to the angle [alpha] that tilts
real.Then, the cosine value of S and preset data are compared.
S140, when the cosine value of described S is less than preset data, to user, send corresponding prompting and report to the police, guides user corrects faulty sitting posture.The angle [alpha] that tilts is larger, and human body head tilts more severe, and now the cosine value of S is S
realbe the trend diminishing, work as S
realwhile being less than preset data, illustrate that human body head inclined degree has exceeded acceptable scope, now, send corresponding prompting report to the police to user, guides user corrects faulty sitting posture, until the angle [alpha] that tilts returns back in acceptable scope.Warning can be vibration or voice message, or the combination of the two.It has been generally acknowledged that 33cm is a desirable distance, therefore preset data is set to 33cm conventionally, when cause S because tilting
realwhile being less than 33cm, said method can and alarm, reminding user corrects faulty sitting posture in time.
Above-mentioned correcting sitting posture method is further comprising the steps of: human body head tilts forward and back angle; By described, tilt forward and back angle and default angle of inclination compares; When detect tilt forward and back angle and be greater than default angle of inclination time, to user, send corresponding prompting and report to the police, guides user corrects faulty sitting posture.Because human body not necessarily exists situation about tilting, also may just tilt forward and back, bow or swing back, now eyes to the distance of target observation thing also may be greater than standard value, therefore can judge by angle of inclination, and to user, send to remind and report to the police.
In addition, a kind of sitting-posture correction device that can implement above-mentioned correcting sitting posture method has also been proposed.
Please refer to Fig. 3 to Fig. 6, a kind of sitting-posture correction device 100, comprise for being fixed to the stationary installation 110 of human body head, be arranged on controller 120 in stationary installation 110, be arranged in stationary installation 110 and the supersonic sensing device 130 being connected with controller 120 respectively, obliquity sensor 140, warning device 150, and give the power supply 160 of these elements power supplies.
The structure of stationary installation 110 is not limit with above-mentioned being described as, as being arranged to glasses type, or hair clip pattern.Also not certain requirement worn to human body head, can be also to hang on ear, can also hang on the outer goodses such as cap.
When above-mentioned sitting-posture correction device 100 is used, can monitor in real time the human body head angle that tilts, give the alarm in time, guides user is adjusted sitting posture.Obliquity sensor 140 can also tilt forward and back angle by human body head, therefore above-mentioned sitting-posture correction device 100 can also guides user be adjusted sitting posture when human body head tilts forward and back, now, only need to tilt forward and back angle and default angle of inclination relatively by what detect.
In addition; sitting-posture correction device 100 also possesses sight protectio effect; the eyes that soon supersonic sensing device 130 will detect to distance S and the preset data of target observation thing compares; if S is less than preset data; by controller 120, drive warning device 150 directly to send warning, do not need by calculating the cosine value of S, to judge again.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
