Intelligent writing tool for preventing and controlling myopia

Abstract

The invention discloses an intelligent writing tool for myopia prevention and control, which comprises a writing head arranged in a main body, a liquid refill or a pencil refill for providing handwriting for the writing head, a position sensor and a light sensor arranged on the main body close to the writing end, a distance sensor and an angle sensor arranged on the main body far away from the writing end, and a prompt unit, and the distance sensor, the position sensor, the light sensor, the angle sensor and the prompting unit are respectively in signal connection with the control circuit. When the pen is used, the distance between the pen and the head is detected through the distance sensor, whether the pen holding position is correct is determined through the position sensor, whether ambient light meets writing requirements is determined through the light sensor, whether the pen holding angle is correct is determined through the angle sensor, and when collected values of the sensors deviate from preset values, the prompt unit is controlled through the control circuit to give out prompts. Writing postures are monitored through various sensors, and vision decline and eye health caused by incorrect postures and insufficient writing environment light are avoided.

Description

technical field

[0001] The invention relates to the field of writing implements, in particular to an intelligent writing implement capable of preventing myopia. Background technique

[0002] According to the statistics of the authoritative part of the country, the myopia rate of juveniles is as high as about 35%. Bad eye use is an important cause of poor vision. Among them, the way of holding the pen when writing is also one of the causes of poor vision. Due to the incorrect way of holding the pen, it is impossible to observe the vicinity of the pen tip when sitting in a normal posture. When it is necessary to observe the vicinity of the pen tip, It is necessary to turn the head sideways to achieve this. For a long time, it will cause poor vision on the one hand and bend the spine on the other hand. How to effectively avoid the occurrence of the above situation and improve the eyesight of children cannot wait to be solved. Contents of the invention
