Preliminary Experimental Study of Marker-based Hand Gesture Recognition System

Abstract—We present the initial studies of a user computer interface based on hand gestures. A set of reflective markers on a glove are used as a simplified basis for hand pose detection. Using coaxial infrared illumination we can maximize the contrast of the markers with respect to the background. The objective is to recognize the shape of various markers with their corresponding position and orientation in the image plane. The system is able to associate the shape of the markers and their corresponding location and orientation angles to various user interface commands. Marker Gestures can be static and dynamic. Whereas static gestures refer to particular hand poses, dynamic gestures correspond to trajectories described with some particular poses. The experiments show that the combined use of the proposed lighting technique, Hu moments and convex hull analysis greatly simplifies the segmentation and identification of the markers allowing the system to obtain reliable information about the pose and orientation of the hand of the user.
