Abstract
In the previous methods to operate the robot, the buttons or touch panel mounted on the robot has been used in many cases. However, there are some problems. Users have to approach near by the robot, and the operation screen larger than the size of the robot is not able to be mounted on the robot. To solve such problems, the projection GUI was developed as interface to implement to a mobile robot. In the projection GUI, the operation screen of a mobile robot is projected on the floor by a projector. The operation commands to the robot can be given by pointing on the screen with toe. However, only a floor was able to project the operation screen in the conventional system. This study aims at development and reliability improvement of the projection GUI which can project to an arbitrary plane.
