Let me use a concrete example: At the same CSCW conference, another thing I heard quite a few times was discussion about teleconferencing, whether through audio modes (telephone) or video modes (video chat). I repeatedly heard that audio only teleconferencing didn’t work that well since people could not see each other’s facial cues. Video conferencing was better, but still a stopgap measure, and many of the CSCW attendees lamented that physical interaction was still unmatched.
