Unlike my friends, I have a soft spot for Beijing's crowded subways, because this huge transportation is not easy to get sick. Few people like Beijing's subway like me, but surely many people have experience with motion sickness.
Because of motion sickness, for a long time, I have a kind of resistance to taking a car. If you are not sitting, you have to open the window, sit forward, keep thinking about the problem or look at the phone to divert your attention.
In theory, the main cause of motion sickness is the conflict between the vestibule and the visual input when the road is not observed in a moving vehicle.
Now, researchers at the University of Michigan have received a patent to ease motion sickness. This system is designed to provide light stimulation to the passenger's visual edge to mimic what the passenger sees outside. The system eliminates conflicts between the vestibule and the visual input.
For specific operations, the system can use glasses or headphones to prevent a disconnect between your sense of movement and what you see. It uses a set of sequentially activated light pipes that mimic the motion of the car in your surrounding view, giving your body a reference frame.
This technology relies more on signal intent to eliminate physiological reactions than to change the car itself. Therefore, this patent can be embedded not only in the car itself, but also in wearable devices.
Not long ago, Uber also issued a similar patent, the style is simple and rude. According to Lei Feng.com, the system reminds the driver or passengers of the current driving conditions through screens and lights. When braking, they use vibration to reduce the pressure on the passengers. For example, the seat vibrates to the left or right to indicate the left. Turn or turn right; upward vibration indicates acceleration, and downward vibration indicates brake. In addition, the system automatically adjusts the seat to allow the driver or passenger to ride in a comfortable sitting position. At the same time, the air conditioning wind is automatically adjusted to provide continuous stimulation, so that the passenger's attention avoids the car's pitch and swing.
When talking about the car, I will give you a shock from time to time, I am afraid that few people like it. Moreover, Uber's system cannot be used in wearable devices and is less portable. In this way, the University of Michigan patents are much taller.
Michael Sivak, a professor at the University of Michigan's Transportation Research Institute (UMTRI), says about half of adults will feel sick when they read a book while driving. He believes that solving the problem of motion sickness for future autonomous driving may be more important than today.
We know that during the driving process, the driver himself will not get motion sickness. However, in autonomous vehicles, everyone is a passenger, and the benefits of being protected from motion sickness by driving will no longer exist.
Brandon Schoettle, a project manager at UMTRI, said that when people enter self-driving cars, they are more likely to do something else than they do now, for example, they want to do some work on a laptop. Video or read a book.
Therefore, Sivak believes that if we don't solve the motion sickness problem, then the productivity of the unmanned supporters may not happen.
This patent has now been released. The head of the University of Michigan said they would contact different suppliers and car manufacturers to commercialize the technology.
