Computer Vision-Assisted Interaction in X3D Virtual Environment on WWW

X3D is the next generation Virtual Reality Modeling Language (VRML97) using Extensible Markup Language (XML) and provides a standardized, portable, and platform-independent way to render dynamic interactive 3D scenes across the Internet. Accordingly, the current paper presents the integration of a more flexible user interface into X3D using computer vision-based techniques. The proposed method enables navigation of a virtual environment on the WWW using only a USB camera and client program, without the need for a mouse or keyboard interface, specific equipment, or environmental setup. Experimental results demonstrate that the proposed approach facilitates an easy to use User Interface (UI) on the WWW.
