I just read an old paper (1992-93) entitled ”Why Do Users Like Video? Studies of Multimedia-Supported Collaboration” by John C. Tang and Ellen Isaacs. The paper is long paper and reports on an investigation they did within SUN regarding different video conferencing solutions. They write many good points but one thing really stood out:
”Rather, we should strive to understand how new forms of interaction can be integrated with the existing ones into people’s day-to-day work”
Too much research in this area today is done on the technical details underneath ( that is what I got my PhD in!).
