Dynamical system representation, generation, and recognition of basic oscillatory motion gestures

We present a system for generation and recognition of oscillatory gestures. Inspired by gestures used in two representative human-tohuman control areas, we consider a set of oscillatory motions and refine from them a 24 gesture lexicon. Each gesture is modeled as a dynamical system with added geometric constraints to allow for real time gesture recognition using a small amount of processing time and memory. The gestures are used to control a pan-tilt camera neck. We propose extensions for use in areas such as mobile robot control and telerobotics. 1 Developing A Gesture Lexicon. Sociological and biological research on human created gestures suggests that while gestures have standard meanings within a society, no known body motion or gesture has the same meaning in all societies [l]. Even in American Sign Language, few signs are so clearly transparent that a non-signer can guess their meaning without additional clues [6]. Thus we are free to create gestures for device control as we see...
