People who write while walking are ruining everything

Save Macarena, the most serious dance a human being can do when you walk down the street and you have to maneuver a pedestrian who sends messages. At first, it looks like they will go against you. Then they finally look at it from the phone, at which point you have to guess who is going left or right. You both turn to the left and realize that this isn’t going to work, so you both turn right and that goes on until you finally go crazy enough to yell at them.

Call Smartphone Six-Step. Take your partner, do it, and throw him out.

We’ve all danced to this furious dance, but now scientists have shown how distracting a pedestrian on the phone is not only for you, but for people as well. Researchers at the University of Tokyo and Nagaoka University of Technology created “one-way experiments” in which two groups of 27 people (one wearing a yellow cap and the other wearing a red cap) went head-to-head. In each experiment, one of the groups gathered three people looking at their smartphones. The investigators placed these unnoticed pedestrians in front, in the middle or in the back of the package, while the top cameras followed everyone’s trajectories and speeds.

In a control experiment in which no one was misled, the researchers saw a previously described phenomenon called lane formation: since the two groups had a relationship, people organized themselves into two or three columns. That is, there was one group that was neat in one direction and the other group in the other, forming two large paths. If you look up, the confused crowds look like the lines of the flag — the only column of red hats, then the only column of those hats, then the other column of red hats, and so on. Crowds then tend to fall into a leading formation, approaching humans that allow pedestrians in front of the crowd to cut off a path.

Each crowd is faced with a number of leaders, each of whom is examining the movements of members who have headed in the other direction to avoid a collision. This interaction between leaders is known as anticipation of each other. “If it’s me and you, I’ll try to predict where you’ll be in the future at the same time, and you’ll try to predict where I’ll be in the future,” says Claudio Feliciani, a computer scientist at the University of Tokyo. paper describing the experiments in the journal Advances in Science. Basically, you’re making assumptions in the second part about how that person will behave and how you should respond. “And that is the mechanism that makes this type of collective modeling possible,” Felicani added.

If you get lost on the phone, this interpersonal relationship, even if it’s enough, is broken. The person approaching you is controlling your movements and predicting your behavior, but you are not simultaneous. You are drifting, which also means people following you. When you finally get in touch with people, you fall into the Six Step Smartphone and the effects of that doubt return to your followers like a multicar car.

Feliconi and his colleagues proved this with the volunteers wearing the cap. In the experiments, pedestrians distracted by the phone placed in front of people slowed down everything behind them. Distracted leaders were unable to negotiate this subtle but complex wordless interaction at the head of the group that was approaching their teammates. So if you look at the routes taken in the direction of reading the phone with the red hat on the phone, instead of the tidy lanes of a normal crowd flag band, there is just a jumble of people with red hats all over the place. (See the mess in the game below.) In fact, the researchers found that the distance of unnoticed pedestrians would trigger the behavior of one of those with a helmet, who was actually paying attention, screwing up the efficiency. other group.

But the researchers did not see the same effect when the distracted pedestrians were placed in the middle of the crowd or in the back. That’s why, even if distracted, pedestrians were able to act as a leader in order to follow the previous person – they had a body to track, as well as their faces buried in phones. “When they are distracted, the people behind them are also lost,” Felicani says. “The people behind it, if it’s distracting, it’s not so important because they can somehow follow others.”
