Ding, Xianghua, Erickson, Thomas D., Kellogg, Wendy A., Levy, Stephen, Christensen, James E., Sussman, Jeremy, Wolf, Tracee Vetting and Bennett, William (2007): An empirical study of the use of visually enhanced voip audio conferencing: the case of IEAC. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 1019-1028. Available online

IBM Enhanced Audio Conferencing (IEAC) is a VoIP-based audio conferencing system that, like several other systems, provides a visualization showing who is present and their states (e.g., speaking, muted). This paper presents the first study of the use of such a system. Drawing on log files collected over six weeks of use by over 1300 corporate employees, and interviews with 10 of them, we look at how and why various features of the system are used and what sorts of practices are supported. Our findings shed light on the factors that drive the use of visual enhancements to audio conferencing, and suggest further research topics.

Kellogg, Wendy A., Erickson, Thomas D., Wolf, Tracee Vetting, Levy, Stephen, Christensen, Jim, Sussman, Jeremy and Bennett, William (2006): Leveraging digital backchannels to enhance user experience in electronically mediated communication. In: Proceedings of ACM CSCW06 Conference on Computer-Supported Cooperative Work 2006. pp. 451-454. Available online

Rendezvous is a conference call solution that leverages Voice over IP, enterprise calendaring, instant messaging, and rich client functionality to enhance the user experience and effectiveness of distributed meetings. We describe the service, and two of its user experience innovations -- the conference call proxy and iHelp -- which function as digital backchannels. We present results from a preliminary user evaluation, and discuss our notion of digital backchannels with respect to the social translucence framework.

Computer programs emerge as the outcome of complex human processes of cognition, communication and negotiation, which serve to establish the meaningful embedding of the computer system in its intended use context.

-- Floyd, 1992, p. 24
