Method for avoiding carsickness based on virtual reality technology

Abstract

The invention discloses a method for avoiding carsickness based on the virtual reality technology. The method includes the steps of sensor detection of the motion state of the head of the human body, signal processing, virtual image dynamic control and tail terminal display; vibration signals, including acceleration in three movement direction, frontal acceleration in three rotating directions and the speed in three rotating directions, of the head of the human body are detected through a sensor; detection signals from the sensor are received through a signal processor, and the motion state information of the environment where the brain of the human body is located is obtained through filtering noise reduction; a virtual image dynamic controller controls dynamic changes of virtual images with information processed by the signal processor as reference through a control algorithm; a tail terminal display projects the virtual images into the human vision; finally the motion received by the human vision is matched with the motion sensed by balance of the human body, so that motion sickness caused by collision between the vision and the perception of a person taking a bus is avoided.

Description

technical field [0001] The invention relates to a method for avoiding motion sickness, which uses virtual visual images to match human body balance perception. Background technique [0002] At present, the widely accepted theory in medicine is that motion sickness is a defense mechanism of neurotoxins. The same area of ​​the brain that checks for ingestion of toxins and induces vomiting also checks for conflicts between vision and balance. When a person is in a motion environment with closed vision, what the person sees is a stationary object in the compartment, and the vision tells that the person is stationary at this time, but at this time the inner ear and other organs responsible for regulating balance have a corresponding reaction due to the movement of the person The corresponding movement information is sent to the brain, so that the brain gets two kinds of inconsistent information. In this way, the brain concludes that one of them is hallucinating and that the cau...
