Because of Apple, we have long been accustomed to large-screen mobile phones, and button phones have become a symbol of backward technology and stay in our memory; because of Tesla, major car companies have followed suit and integrated traditional buttons into the central touch The control screen is large, and the size is showing a trend of increasing. For example, Byton Motors' first luxury pure electric SUV M-Byte has a 48-inch central control screen, just like an in-car LCD TV.
If one day "turns back in time", the car returns to the era of buttons + small screens, what would you think?
Not long ago, Mazda announced that starting from the 2019 Mazda 3, the large-size central control touch screen of the new car will be cancelled, and only a small piece of display screen placed in front of the driver’s line of sight will be retained. The reason is for driving safety. consider. A Mazda engineer said: “According to our research, when drivers touch the touch screen interface in any vehicle, they will inadvertently apply torque to the steering wheel, and the vehicle will deviate from its lane position, and when using the touch screen, the driver must look towards Screen, which also increases the risk of traffic accidents."

In this regard, anyone who has ever driven a car should feel the same. It's just that the large touch screen is cancelled, and those who are used to smart phones will inevitably feel out of touch with the times, and the car's intelligent connection and entertainment functions may be weakened. The necessity of Mazda’s counter-trend has aroused people’s thinking and discussion.
Using a large touch screen will affect driving safety
Actually 2 years ago,The American Automobile Association Road Safety Foundation has issued a warning to car companies: operating a complex functional interface while driving is no less dangerous than using a handheld device or driving while drunk.
At that time, the American Automobile Association and the University of Utah conducted a study to find 120 drivers between the ages of 21 and 36, and asked them to test drive 30 different new cars with large touch screens. Operate the in-vehicle system to make calls, adjust the radio frequency band, set navigation, etc. through voice control or touch control. At the same time, the staff use cameras and other equipment to identify whether the driver is looking at the road or not looking at the driving area in front to determine the degree of distraction.
It turns out that any operation on the large touch screen will cause the driver to be distracted and endanger driving safety. Listen to music It is considered as mild distraction, setting navigation is serious distraction, the offset time is as long as 40 seconds, the driving field of vision is constantly switching between road conditions and the screen, and the probability of traffic accidents is the highest.
It is worth mentioning that among the 30 new cars evaluated, Tesla Model S was rated as the driver’s attention At that time, Tesla’s minimalist aesthetic interiors and various black technologies were as amazing as Apple’s when they came out, but many users just didn’t adapt to the car, and the operation became more cumbersome. Pull over and study slowly. With the rapid development of mobile Internet, logistics network, and autonomous driving technology, large touch screens seem to have become standard, but at the same time, there are more and more problems in their use. We can be said to be happy and painful.
Key operation has irreplaceable advantages
Actually, according toPersonal car use and test drive experience found that the main defect of the touch screen is that it is not easy to "blind operation", requiring the driver to stay on the screen for a long time.
Because the many functions on the car are integrated on a single screen, the driver must allow the driver to park his attention on the large touch screen of the car for longer, otherwise, because the car system basically cannot give recognizable feedback, neither I know which function I am operating, or I cannot find the corresponding function sub-menu.
The traditional buttons are different. The functional areas are arranged according to a certain logic, and the functions are clear and single. Different buttons have different touch feelings and different button shapes and sizes. , With a sense of damping as a distinction, users can form body memory within a certain period of time to achieve "blind operation".
So what about voice control and gesture control?
In fact, the efficiency of these two methods cannot be compared with the physical buttons. Whether it’s voice control or gesture control, let’s not talk about the recognition success rate. If you want to consciously conceive sentences and correct pronunciation/writing during the driving process, then there is definitely no direct control of the buttons, or “one-button operation” ". In other words, the information that the touch screen can display and prompt, the physical buttonsIt can be used with a small screen, but the touch screen cannot give you the touch and blind operation of the physical buttons.
One more thing, the current touch screen response speed of many cars is worrying. The mainstream price of family cars is limited to cost. The screen is driven by Qualcomm and MediaTek’s mediocre chips. According to the high standards of modern people, the operation is generally smooth. The NVIDIA Tegra on-board computer used by Tesla and Audi has strong driving performance, but users Few. The combination technology of buttons + large screen is already very mature, with little difference in fluency.
Of course, the touch screen has many advantages over the traditional button + small screen combination, which is equivalent to having an extra PAD, which can provide more exciting audio and video entertainment and other content. But compared with driving safety, there is no need to say which is more important. In response, Marshall Duney, President and CEO of the American Automobile Society, once said: “Information multimedia systems should be safe and easy to use.However, various manufacturers are now focusing on rich content as their selling point, which will complicate the driver’s operation and often result in a very bad user experience. ”
The voice of Mazda, which has always been maverick, has also won the support of many netizens. It seems that Mazda’s The contrarian move resonated with them.
Mazda also received support from most netizens on Hacker News, a well-known overseas IT information website. The top comment on this news comes from a user experience expert who praised Mazda for really starting from the user's perspective. Judging from the news response, Mazda's cancellation of touch screens in new cars in the future is likely to cause a wave of retro waves of physical buttons.
Editor's summary: on the touch screen and driving safety issues. The mainstream view in the industry is touchCombination of screen and physical buttons. The operation during driving is realized by physical buttons to adjust the volume, media playback, etc.; when parking is changed to a large touch screen, so that modern people's high demand for technological experience and content presentation can also be met. Of course, the realization of this approach must also consider the procurement cost, key layout design and other issues.
In addition, from this matter, we also feel Mazda's sincere concept of driver-centeredness. In the auto market, it is a unique but lovely existence.
