Five panelists provide an interesting set of contrasting points of view of the HCI field from four distinct disciplines: Business, Computer Science, Information Science, and Psychology. Panelists are asked to respond to six questions in their presentations that address what their particular field offers that is unique, what seems to be quite similar, the effects of the overlaps, and advice for the future. Many of the panelists represent multiple fields, providing a unique opportunity to address the issues of overlap.
