NECTAR (2004-2009) was a NSERC network of Canada's leading university researchers in human-computer interaction (HCI) and computer-supported cooperative work (CSCW). Participants came from 6 Canadian universities and are world-class experts in these fields. The network was focused on collaboration technologies. Its vision is to investigate technological and social issues to make computer-supported collaboration more efficient, more productive, and more natural. Archives of the final meeting, with demos of the many technologies created in the 5-year project, can be viewed here
