VisiCon

Abstract

The miniaturization of image projectors leads to the expectation that projectors could be embedded in mobile devices such as cellular phones and PDAs. A projector mounted on a mobile device, freely movable in 3D space under user control, could operate not only as an output device but also as an input device for enabling humans to manipulate mobile robots. We therefore explore the possibilities of human-robot interaction techniques using handheld projectors. For this purpose, we propose an innovative interface called VisiCon. We have also developed a cooperative game, CoGAME, in which players guide a simple robot using handheld projectors. In this game, users can connect projected maps together, and cooperatively lead a robot to a specified goal. In this paper, we explain the techniques used in CoGAME, and present an evaluation.
