Real-Time Control Operation Support of Unstable System by Visual Feedback

Abstract

In this paper, we show that an inverted pendulum can be stabilized manually even when a user does not know the physical characteristics and the current state of the pendulum. We display two markers: one indicates current position of the base of the pendulum and the other indicates the target position where the base should be located 0.3 seconds later. Subjects can stabilize the pendulum for a significantly longer time than seeing the real pendulum directly, just by chasing the target marker.
