Abstract

This paper suggests a system that is able to orient a camera around its pan and tilt axis with the same high dynamic as a human orients his eyes. Since the device is a part of a gaze–driven head–mounted stereo camera system, beside the high dynamic also the compactness of the device is important. Therefore a small and light–weight system is developed which is mounted on a humans head near the ears. Based on the experience of a previous version a small piezo–actuator driven parallel kinematics is developed. The kinematic solution, a dynamic simulation and the step response behavior of the new device are presented.
