Recently a robot has been experimentally used an automatic presenter instead of human. We have proposed such a presentation system based on the "PowerPoint driven" approach, where a robot can move in synch with a PowerPoint slide show by using an audio signal as a carrier of the motion data. This system, however, has a fatal problem such as low scalability and low editing efficiency of the presentation contents. In this report, based on the " robot driven" approach, we solve the above fatal problem by introducing a control method with a virtual key code as well as a presentation script. To guide the audience's line of the sight to a relevant object on a display, a laser pointing control method of the robot is proposed and the validity of the idea is confirmed by an experiment system.
