The walk experimental track was installed in the laboratory. Two kinds of walks were carried out to the experiment participant. One is usually walked. Another one is walk while doing 1 digit addition task with smartphone. Measurement items are a front visual confirmation rate by an eye mark recorder, the number of answers and the number of correct answers of 1 digit addition task, and etc.. As a result, there are two types of walks while using a smartphone. One is a smartphone-oriented type, and the front perception rate for walk was 25%. Another one was a walking-oriented type, and the front perception rate for a walk was 35%. In the usual walk, the front is sighted 100%. Therefore, it was neglected to check the front for a walk of both types, and the very risky thing became clear.
