Hand gestures would be an intuitive and ideal way of exchanging information with other people in a virtual space guiding some robots to perform certain tasks in a hostile environment or interacting with computers. Hand gestures can be divided into two main categories static gestures and dynamic gestures. In this paper a novel dynamic hand gesture recognition technique is proposed. It is based on the 2D skeleton representation of the hand. For each gesture the hand skeletons of each posture are superposed providing a single image which is the dynamic signature of the gesture. The recognition is performed by comparing this signature with the ones from a gesture alphabet using Baddeley s distance as a measure of dissimilarities between model parameters. Keywords and phrases hand gesture recognition skeleton orientation histogram Baddeley distance. 1. INTRODUCTION The goal of the dynamic hand gesture recognition technique proposed in this paper is to offer a method of guiding robots from a distance using hand gestures. It is .
