is a new video conferencing interface that superimposes transparent images of a computer's desktop over video images of the user to allow the user to look at the video and desktop at the same time. This results in a 'ghost' image of the user on the screen. When the user points at something, "his video reflection appears to touch objects on the screen." The computer scientists also developed a two-user version in which the 'ghost' images of the two users appear side by side. Both can alternatively take control of the desktop, again allowing a better collaboration. A Mac version is expected within months and a Windows version in two years.
