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.
