Abstract

A sitting posture sensor mainly includes a photographic lens, an image analysis and comparison device, and a warning device. The sitting posture image of the user is continuously captured by the photographic lens and sent to the image analysis and comparison device, and the image is captured When the angle or distance between the sitting posture and the set standard sitting posture reaches a certain deviation, the warning device will send out a warning signal to inform the user that the sitting posture is incorrect and need to be corrected, and when the user’s sitting posture returns to the correct position, the warning signal will be It will stop, so as to effectively cultivate the user's correct sitting habits, reduce the chance of myopia due to poor sitting posture, and benefit the development of physical and mental health.

Description

Sitting position sensor

This creation is related to a technical field that uses images to sense the user's sitting posture and remind the user to maintain a good sitting posture.

Maintaining a correct sitting posture is very important, and it cannot be ignored for school children. In addition to being beneficial to the growth of the body, the most important thing is to prevent the formation of myopia or the deepening of myopia due to poor sitting posture. There are many kinds of sitting posture detectors. Most of their principles are infrared detection and ultrasonic detection, using the feedback of linear wave reflection distance to sense the change of position, but their sensing effect is poor and often misjudgment Circumstances; in addition, there is the use of acceleration sensors (G-senser) to detect, through the motion detection mode sensing, but this design must be worn on the user, there is an additional burden, the error value is still large , And can only detect partially, and the cost is not economical, and can not meet the practical requirements.

This creation is a sitting posture sensor, which mainly includes a photographic lens, an image analysis and comparison device, and a warning device. The photographic lens continuously captures the user’s sitting posture image and sends it to the image analysis and comparison device. When the captured image’s sitting posture and the angle of the set standard sitting posture reach a certain deviation, the warning device will send out a warning signal to inform the user that the sitting posture is incorrect and need to be corrected, and when the user’s sitting posture returns to the correct position, a warning signal Will stop and reach Can effectively cultivate the user's sitting habits, and benefit the development of physical and mental health.

Figure 1 is a schematic diagram of the combined structure of the creation

Please refer to Figure 1. The sitting posture sensor of this creation includes a camera lens 1, an image analysis and comparison device 2, and a warning device 3. The camera lens 1 can continuously capture the user’s sitting posture image 4. Send to the image analysis and comparison device 2, and when the angle or distance between the captured image and the set standard sitting posture reaches a certain deviation, the warning device 3 will issue a warning signal to provide the user that the sitting posture is incorrect and needs to be corrected. And when the user's sitting posture returns to the correct position.

An important feature of this creation is that the photographic lens 1, the image analysis and comparison device 2, and the warning device 3 are integrated on a single module 10, which can be combined with other appliances on the desk, such as bookshelves, desk lamps, Or other fixed utensils, in addition, this creation can also be assembled on any movable objects, such as pencil boxes, dolls and other objects. Before use, first place the object combined with the authoring module 10 in a position near the user, adjust the correct sitting posture, press the setting button 21 to create the image data of the correct sitting posture, and then the author can continue to detect and use The sitting posture of the person is compared to whether it is within a certain range with the set sitting posture, and when the sitting posture image deviates by a certain range, a warning signal is issued.

The setting button of the created image analysis and comparison device 2 also has the function of adjusting the offset ratio setting value, such as setting the overlap ratio of the captured image and the setting image to less than 95% In addition, the warning signal of the warning device 3 created by this invention can be set to different signal sources, such as sound, light, or vibration, to achieve the purpose of reminding the user.

In summary, this creation uses image capture to compare the sitting posture of the user, which is obviously more accurate, and the overall integration into a single module structure is easy to implement and use, and has achieved significant progress. Meet the requirements of the patent.
