Google's self-driving car team Waymo applied for anti-motion sickness patent

Published in 2018-07-02

More than 100 years ago, when everyone said that they wanted a faster horse, Ford put the car into mass production, and since then the car has entered the homes of ordinary people at a low price.Today, we will not say that we want a faster Malay travel.


Thanks to the progress of transportation, we can travel faster and more comfortably.However, there are exceptions to everything. Even if it is the Tesla Roadster, there are still people who will get motion sickness when they sit up.

Many people are troubled by the problem of motion sickness when they travel, a motion sickness, and then the speed of the luxury interior and advanced driverless technology have lost their meaning, because every motion sickness is suffering.

Many people are troubled by the problem of motion sickness when they are traveling. Once the motion sickness, the speed of the luxury interior and the advanced driverless technology have lost their meaning, because every time motion sickness is suffering.Whether it's driverless or manual driving, the passenger experience should always be in the first place.

In order to provide users with a better travel experience, and to pave the way for the future of unmanned driving, the industry has gradually paid attention to the prevention and treatment of motion sickness symptoms.Recently, the autopilot company Waymo applied for a patent specifically to solve the symptoms of motion sickness when passengers take an unmanned vehicle.As the saying goes,to suit the remedy to the case , before we understand Waymo's patent plan, let us first understand why we have motion sickness.


/ The chief culprit of dizziness - the vestibule /


Whether it's motion sickness, turning circles in place, or feeling the dizziness when playing the recently hot "eat chicken" game, these vertigos are essentially due to our perceived balance of the nerves - the vestibule .

The vestibule is our balance organ, located in the inner ear, capable of sensing the state of motion of the human body and the position of the head in space, such as acceleration and deceleration, and the perception of the head facing up and down.There are many hair cells growing in the vestibular organs. These hair cells are the vestibular sensory cells, and the lower ends are connected to the brain through nerves. They are like a grass, which can sway with the movement of the human body. Our brain passes the shaking of these "grass" knows the movement state of the body and the spatial position of the head.


For example, if we close our eyes and sit on a roller coaster, the roller coaster will accelerate and slow down and keep flipping and jumping. Although we can't see the changes of the outside world, we can generally perceive whether we are flipping forward or turning the whole world upside down. It is the vestibule that perceives all this.


/ Why do we get motion sickness /


When the actual physical state of the body is not coordinated with the balance, the brain will have a sense of dizziness.Many people don't have a sense of dizziness during the driving process. They can even brush their friends to talk and laugh, and laugh at the rivers and lakes. But once the car slows down or stops, or bumps all the way, we may not even get the phone.This is because during the driving process, the body's state of transport is consistent with the sense of balance, and our body has not felt.Once the brakes were stopped, although the body stopped moving, the "grass" in the vestibule was still swaying due to inertia. At this time, the brain received the wrong message, thinking that the body was still moving, in this serious imbalance under the influence, it is difficult not to get motion sickness.




When the visual input is inconsistent with the balance, the brain also produces a sense of dizziness.The most typical thing is that when we play 3D games like “eat chicken”, because the picture is too realistic or too much, we seem to be running, jumping and shooting inside.So, the visual input tells the brain that you are constantly moving.But the vestibule told the brain that you were sitting quietly and didn't even turn your head.After a long time, the brain can't get consistent information, so it will cause dizziness.The same is true in the car. The sight seen in front of you is not compatible with the balance of the body. Your brain will tell you, "You have motion sickness."




In addition, when the human body is too hungry or fatigued, it will also get motion sickness.

In addition to the vestibule in the "trick or treat", psychological factors can not be ignored.For example, some people may smell dizzy when they smell gasoline or the smell of air inside the car, and even vomiting seriously.For example, some people may feel dizzy when they smell the smell of gasoline or the smell of air inside the car.Serious even vomiting.Similar to taste aversion learning, this part of people will be associated with motion sickness every time they feel motion sickness, such as the smell inside the car, which has formed a kind of reflex behavior for a long time, even if you don’t take the car, but only one When you smell the inside of the car, you will think of motion sickness, and then feel the motion-like turn.

As an unmanned company, Waymo's research is naturally based on driverless development.By studying the cause of motion sickness, the Waymo unmanned vehicle will choose an anti-motion sickness route for the motion sickness passengers: a smooth lane with a smooth passageway and avoiding sudden acceleration or emergency braking.Of course, the cost is that the time spent on the road will be longer, so it is inevitable to go out early.



According to the patent information, the unmanned vehicle will remind passengers who are prone to motion sickness not to look down on the mobile phone while driving, to avoid looking down for a long time, and to recommend passengers who are prone to motion sickness to sit on a relatively stable seat.This is equivalent to a little assistant, telling you some tips to prevent motion sickness when you get in the car.

Unmanned driving belongs to the vertical field of artificial intelligence. Since it is artificial intelligence, the humanized side is naturally indispensable.When the passengers experience motion sickness, the Waymo driverless system automatically adjusts the driving style, slows down the driving speed, automatically selects the smooth road driving, and avoids the state of accelerating deceleration and emergency stop for a long time.This is equivalent to an intimate old driver who actively slows down when you find out that you are sick, which relieves the sense of dizziness.


/ Anti-motion sickness, not just Waymo /


Prior to Waymo, Uber also submitted a patent on anti-motion sickness-sensory simulation system, providing a full range of anti-stun experience.In Uber's car, there will be an AR system that will present the environment outside the car in the car, making up for the lack of visibility in the car.At the same time, through the car's internal lights, sound prompts, airflow steering, seat vibration and other behaviors, passengers can also feel the next behavior of the vehicle during non-driving operations, reducing passengers' riding pressure.



In January of this year, researchers at the University of Michigan also applied for a patent on anti-motion sickness.The patent can simulate the environment outside the car through a set of wearable devices, preventing the disconnection between our motor nerves and the environment we see, keeping the sense of vision and balance consistent, so that passengers do not have the pressure of motion sickness, it will Starting to focus on other things has greatly improved the fun of the journey.




At present, although there is no guarantee that the patent will be commercialized, researchers at the University of Michigan are actively contacting the relevant companies, hoping to turn them into commercial products.

As an important way of modern travel, cars carry too many expectations, commuting, traveling, and spring travel.The national promulgation policy is vigorously developing unmanned driving, and the unmanned driving technology is gradually maturing. The convenient transportation mode should benefit more people, and how to ride a driverless car without motion sickness is presumably the first breakthrough of the driverless car experience a problem.

The end of all technologies is ultimately to serve humanity. Recently, more and more enterprises and research institutes have begun to focus on improving passengers' ride experience. More and more people are beginning to realize that no matter whether they are driving or driving, they can It is good driving to bring a good experience to the user.

As a state-level high-tech enterprise that has been deeply involved in the industry for more than 20 years, Soling has always been customer-centered and constantly innovating, providing intelligent, personalized and professional travel solutions to customers around the world, bringing a better travel experience.
