specific Embodiment approach 1

[0027] Embodiment 1: The IMU-based interactive sitting posture correction device of this embodiment can be a software function module integrated in a processor, or it can be hardware solidified by software that meets the functional requirements.

[0028] The IMU-based interactive sitting posture correction device of the present embodiment is as follows: figure 1 shown, including:

[0029] The sensor information receiving module is used for receiving measurement information collected by the sensor.

[0030] The Kalman filtering module is configured to filter the acceleration, angular velocity and magnetic field information to obtain filtered acceleration, angular velocity and magnetic field information.

[0031] The digital motion processing module is used to obtain orientation information through calculation according to the acceleration, angular velocity and magnetic field information.

[0032] The sitting posture information calculation module is used to obtain the sitting...

specific Embodiment approach 2

[0034] Specific embodiment two: this embodiment is different from specific embodiment one in that: the alarm module includes an early warning judgment unit, a timing unit and a reminder unit, wherein the early warning judgment unit is used to control the timing when the judgment result is detected to be an incorrect sitting posture The unit starts timing, and if the judgment result is always incorrect sitting posture within the predetermined timing time, the reminder unit sends a reminder signal when the predetermined timing time ends.

[0035] This embodiment provides a specific way to correct according to the judgment result, that is, to check whether the judgment result is correct, and if the judgment result is always incorrect within a period of time, a reminder signal is sent to facilitate correction. Whether the judging result is correct can be by comparing the sitting posture information with the preset sitting posture information, and judging whether the sitting posture...

specific Embodiment approach 3

[0037] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the reminder signal is used to control the vibration motor, light emitting device, loudspeaker or any combination thereof to send corresponding prompt information, and the prompt information is used to remind the user to adjust the sitting posture. Active correction.

[0038] This embodiment discloses which hardware can be used to send out reminder signals. Vibration signals can be sent out by motors, light signals can be sent out by light emitting devices, sound prompt signals can be sent out by loudspeakers, or a combination of the above-mentioned various signals can be used. The purpose of reminding can also be realized through screen animation, vibration or occurrence of the computer terminal or mobile phone terminal. After the user feels these signals and knows that his sitting posture is incorrect, he can actively correct his sitting posture. The hardware for ...

Abstract

The invention relates to an IMU-based interactive sitting posture correction device, a sitting posture correction appliance and monitoring software and belongs to the technical field of health correction. In order to overcome defects of high cost, poor correction effect, slow response, poor safety and short service life in the prior art, the IMU-based interactive sitting posture correction device is proposed and comprises a sensor information receiving module used for receiving measurement information acquired by a sensor, a Kalman filtering module used for filtering the measurement information to obtain an accelerated speed, an angular speed and magnetic field information after filtering, a digital movement processing module used for performing calculation according to the filtered measurement information to obtain azimuth information, a sitting posture information calculation module used for obtaining sitting posture information according to azimuth information and preset reference information, as well as a sitting posture judgement module used for comparing the sitting posture information with the preset sitting posture information threshold value to obtain a judgement result and performing correction according to the judgement result. The IMU-based interactive sitting posture correction device, the sitting posture correction appliance and the monitoring software are applicable to correction of sitting posture of human bodies.

Description

technical field [0001] The invention relates to an IMU-based interactive sitting posture correction device, a sitting posture correction device and monitoring software, belonging to the technical field of health correction. Background technique [0002] With the development of society and economy, the overall vision level of teenagers is declining, and most of the children on campus wear glasses. In the learning process, incorrect sitting posture is a very important reason for myopia. Incorrect sitting posture will not only reduce the child's learning efficiency, lower grades and loss of confidence, but also affect physical health, resulting in decreased vision and curvature of the spine, hindering the normal development of bones in adolescents. It is very important for teenagers to maintain a good sitting posture, but due to their lack of self-awareness, they will involuntarily bend over or even lie on the table during the learning process, and it is impossible for parents...
