Study: Humans are adapting to walk and text

People who use their phones while they walk have modified their behavior, resulting in a more cautious gait, a new study indicates.

A new research suggests that humans evolved to accommodate walking and texting.

Texting – or checking social media or watching a video – while walking causes people to walk in a special movement pattern that protects them from accidents, according to a new study.

People who look at their phones while they walk subconsciously "shorten their step length, reduce step frequency, lengthen the time during which both feet are in contact with the ground and increase obstacle clearance height," say researchers, effectively modifying their gait in order to compensate for the distraction.

By adopting this new walking behavior, texting walkers protect themselves from falling down or walking into other people or objects in their environment.

Researchers at the universities of Bath and Texas asked thirty participants, all between 18 and 50 years old, to walk around a specially designed obstacle course while attempting to text. The researchers then noted how they altered their movement to cope with the reduced focus and vision.

They found that those who were texting took longer to complete the course, because of their adapted gait.

Last year, a team of researchers from the University of Queensland in Australia found that smartphone use while walking makes people more likely to dawdle, weave, and possibly lose their balance.

Apart from walking funny, researchers say, texting while walking forces the body into a hunched position which can lead to poor posture and balance. In addition, the distractions can make walking around dangerous.

Earlier this summer, Utah Valley University unveiled a texting stairway lane on its Student Life and Wellness Center building.

Lanes specially designated for people who want to walk as they use their cell phones have been featured on TV programs and in advertising. Text-while-walking lanes were recently spotted in Antwerp, Belgium as a marketing stunt for a cell phone chain store. Last fall, the Internet was agog with news of texting-while-walking lanes in the Chinese city of Chongqing. The lane, which is dedicated to pedestrians who are glued on their phones, was rolled out in a theme park called Foreigner Street.

Meanwhile, pranksters in New York found another solution for phone-distracted pedestrians. Wearing jackets labeled "Seeing Eye People," they used leashes to guide people who were engrossed in their cell phones.

While technology is meant to accommodate the way people live, the texting-while-walking gait suggests that humans are adapting to cope with technological change.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to
