Description

Technical Field

[0001] The present invention relates to the technical field of motion sickness treatment, and more particularly to a motion sickness treatment system taking into account the motion sickness constitutions of different passengers. Background Art

[0002] Motion sickness, also known as motion sickness, is a physiological discomfort phenomenon that occurs during exercise, mainly manifested by symptoms such as nausea, vomiting, and dizziness. Motion sickness, as a type of motion sickness, has seriously affected people's travel experience, especially for Chinese residents. According to statistics, about 41% of people in the world have experienced varying degrees of motion sickness in the past five years, and the motion sickness rate in my country is as high as 61.7%, ranking first in the world. Among the families surveyed in my country, about 70% of family members have suffered or are suffering from motion sickness.

[0003] Motion sickness has long been a problem in the automotive and transportation industries. Existing methods for dealing with motion sickness mainly include audio-visual combinations and vehicle parameter adjustments. However, these methods have certain limitations in practical applications, such as the inability to make personalized adjustments based on the degree of motion sickness of different passengers. In addition, the differences in motion sickness among different genders and age groups also pose challenges to the prevention and treatment of motion sickness.

[0004] The study found that women are most likely to suffer from motion sickness at the age of 11, while men are most likely to suffer from motion sickness at the age of 21. The results of the global motion sickness survey data show that the number of women suffering from motion sickness is higher than that of men. This shows that there are significant differences in motion sickness problems in terms of gender and age.

[0005] Therefore, how to provide a motion sickness treatment system that takes into account the motion sickness physiques of different passengers is an urgent problem that needs to be solved by those skilled in the art. Summary of the invention
