Texting pedestrians aren' t just an annoyance to their fellow walkers, but something dangerous to themselves. "I was checking emails while walking to work this morning," said Wolbert van den Hoorn. "But it has a serious influence on the safety of people who type or read text while walking. " Anecdotes back him up. A tourist from Taiwan walked off a port near Melbourne last month while checking Facebook-bringing an abrupt, and icy end to a penguin-watching visit. Another shopper in the U.S. was too addicted to his mobile phone to notice the fountain ahead, walking straight into it. And as mobile-phone use has grown-to about 77% of the world's population, the study says-so has the number of phone-related accidents. The number of U. S. emergency-room visits linked to phone use on the move doubled to as many as l,500 between 2005 and 2010, an Ohio State University study recently showed. Authorities world-wide have taken note. Signs on Hong Kong's subway system advise passengers in three languages to keep their eyes off their phones. Police and transport authorities have also warned the danger in Singapore, where the Straits Times newspaper ranked it as "No.2 Bad Habit", due to the rising number of road deaths. Some U.S. states, including New York and Arkansas, are even considering bans on this act. The Australian study used 26 volunteers, a third of whom admitted having hit objects while texting. They were fitted with different equipment in different parts of their body, and asked to walk 8.5 meters three times-once without a phone, once while reading a text and once while writing a text-while eight cameras captured the action. Volunteers using the phone walked slower and with shorter steps (and slowest of all when typing), and, more seriously, they locked their arms and elbows in-like "robots", in the researchers' words. That forced their heads to move more, throwing them off balance. "In a pedestrian environment, inability to maintain a straight path would be likely to increase potential for hits, falls and traffic accidents," said Mr. van den Hoorn. "The best thing to do is to step aside and stop, or keep off the phone." Which of the following about "Texting pedestrians" is WRONG?
People who type while walking. People who phone while walking. People who text while walking. People who read text message while walking.
