writes with a link to IBM research on the limits to and lessons learned from two context-aware computing projects
"As the researchers Moran and Dourish put it, 'Context awareness is fine in theory. The research issue is figuring out how to get it to work in practice.' The article lays out two attempts by IBM to do just this. Grapevine and Rendezvous are services offered to IBM employees as a means of looking into the promise and perils of context-aware computing. From these two experimental services the authors have drawn several valuable lessons."
From the article: "What computer scientists commonly call context often has more to do with technology than with work situations, people, or frames of mind."
