Improvement and Persistence of Safety Check Behavior by Praise

Abstract

The purpose of this study is to investigate the effect on the improvement of user's safety confirmation behavior by checking whether the user is confirming safety confirmation while driving, and by providing guidance including praise according to the degree of safety confirmation. We developed a system in which a driving guidance agent judges the user's safety confirmation behavior using face orientation estimation, and then gives guidance, including praise, according to the degree of safety confirmation and the driving situation. We conducted an experiment to investigate the change in safety confirmation behavior before and after the user experiences the driving guidance agent using an eye tracking device, and whether the safety confirmation behavior is sustained, and compared the effects of praise and no praise guidance, respectively. The results of the experiment showed that there was a possibility that the safety-checking behavior was improved and sustained better with the praise instruction than with the no-praise instruction.
