James, David and Stanton, Jeffrey (2011): Beyond being (t)here: the social and personal implications of making music at a distance. In: Proceedings of the 2011 iConference 2011. pp. 686-687.

This literature review discusses the social phenomena that surround and affect the process of making music with a distant collaborator, and probes future directions for this area known as "computer supported collaborative music" [3]. Articles were sampled by searching the SCOPUS, EBSCOHOST, IIMP, ACM Digital Library and Google Scholar for abstracts that included the keywords "collaborative music" or "networked music". From this group of article the author highlights studies that have reported factors that altered the experience of collaborative composition. Preliminary results indicate that novices to music composition can use metaphors, (present in tools that do not replicate face to face interaction) to compose pieces with others without formal music training.

Munteanu, Cosmin, Baecker, Ronald M., Penn, Gerald, Toms, Elaine and James, David (2006): The effect of speech recognition accuracy rates on the usefulness and usability of webcast archives. In: Proceedings of ACM CHI 2006 Conference on Human Factors in Computing Systems 2006. pp. 493-502.

The widespread availability of broadband connections has led to an increase in the use of Internet broadcasting (webcasting). Most webcasts are archived and accessed numerous times retrospectively. In the absence of transcripts of what was said, users have difficulty searching and scanning for specific topics. This research investigates user needs for transcription accuracy in webcast archives, and measures how the quality of transcripts affects user performance in a question-answering task, and how quality affects overall user experience. We tested 48 subjects in a within-subjects design under 4 conditions: perfect transcripts, transcripts with 25% Word Error Rate (WER), transcripts with 45% WER, and no transcript. Our data reveals that speech recognition accuracy linearly influences both user performance and experience, shows that transcripts with 45% WER are unsatisfactory, and suggests that transcripts having a WER of 25% or less would be useful and usable in webcast archives.
