Barry G. Blundell, PhD, is a physicist and engineer who has worked in the area of 3-D display and interaction systems since the late 1980s. His research interests in the development of new forms of creative digital media are intended to advance natural and synergistic interaction with the digital world. The author is involved in promoting new technologies and techniques for distance education--particularly for use in third world countries--and also in highlighting ethical issues arising as a consequence of the deployment, networking, and accessibility of computer systems.
