Target object announcement by synchronous blinking of a robot and an object

In this paper, we report the investigation about previous notice of the robot target to reduce scary emotions by synchronous blinking of a robot and an object. Although robots´ previous notice is an important concept to secure users, it is difficult to plan previous notice because highly sophisticated robots are very complicated. To solve the problems, we have studied a single light based object announcement. In this paper, we especially focus on cooperative works between a user and a robot, and investigate a target object announcement by synchronous blinking of a robot and an object. Throughout the experiments, we confirmed that our approach can reduce scary emotions compared to the approach using only a light on the robot.
