He has over twenty five years of industrial experience with major American computer companies in virtual reality, enterprise consulting, networks, operating systems and telephone systems.

President of Xtensory Inc, a virtual reality company based in California, America. He started Xtensory Inc in 1991 doing VR consulting. Xtensory Inc is based in California, America.

Xtensory’s VR consulting experience concentrates on creating networked, collaborative immersive environments for learning by combining the entertainment industry and training.

Projects have included work for NASA’s virtual collaborative clinic. Other projects are for Toshiba, Disney, Heitman’s virtual shopping mall, Boeing, Federal Aviation Authority. Mayo Clinic, Fraunhofer Institute, Schlumberger, Paradigm Simulation (Vega), Lockheed, Army’s TACOM (requisition number AMSTAT-RN-0-3400) and Delmia (robotics).

Xtensory has received various american government contracts
Enhanced Multiplatform, Integrated Virtual Urban Warfare Simulation. Navy SBIR N99-063.
Soldier-Computer Interface for Enhanced Interaction and Communication. Army SBIR A95-035. Contract number DAAB07-96-C-D608.

Xtensory has many years of virtual reality expertise gained during the past years designing applications for collaborative networked "Distributed" Virtual Environments (DVE). In a tele-immersive DVE a simulated world runs on several computers. The computers are connected over a network and people using those computers are able to interact and collaborate in real time, sharing the same virtual world.

An example is Xtensory’s work for NASA’s virtual collaborative clinic (http://www.nasa.gov/centers/ames/news/releases/1999/99images/virtualhospital/virhospx.html).

The Virtual Collaborative Clinic was a medical training application operating in a DVE, developed by the NASA Center for Bioinformatics. This application enables collaborative viewing and manipulation of three-dimensional medical images obtained from MRI or CAT scans. The benefit is to enable experts to collaborate in a DVE in developing solutions to challenging operational, engineering, science, and medical problems.


Many different media (audio, video, 3D, sensor data) streams had to be exchanged among the participants, each one with different Quality of Service (QoS) requirements. A session management mechanism had to be provided to handle the establishment and release of each session, and creation of each data channel. Network usage was very carefully managed to enable the realization of such a system, where many users receive and send many streams. This required an efficient delivery and content update mechanisms to distribute events and media streams.

One issue in such a collaborative virtual environment though was how distributed clients and servers share and maintain the same resources. Moreover this problem has to be solved in the framework of many hardware and software platforms, and networking systems. One way explored was the use of distributed and decentralized market mechanisms for resource sharing in such a multimedia network coupled with new approaches to the pricing of network resources.
