This, in turn, should be used to convey emotions, expressions and gestures. Finally, and perhaps most important of all, the system should interact with the user in real time, in a fluent and believable manner.

Furthermore, the authors raise concerns about the possible deleterious effects of diminishing aspects of publicness on English healthcare. The most important of these is a decrease in accountability
