There are no required texts for this course. Two recent surveys give a good overview of current research in HCI and are worth having on a shelf nearby:
BGBG: "Readings in Human-Computer Interaction:
Toward the Year 2000" by Ronald M. Baecker, Jonathan Grudin, William A.S. Buxton,
Saul Greenberg (Eds.), Morgan Kaufman Publishers, San Francisco, CA, 1995.
This is a large (70 contributions) collection of contemporary research papers in HCI. The
editors have added a lot of introductory text to situated each paper in the context of the
book and its sections, so it is much more coherent than a normal edited volume of papers.
Carroll: "Human-Computer Interaction in the New Millenium" by John M. Carroll (Ed.), Addison-Wesley, 2002. A smaller but more up-to-date collection of 29 papers including special survey issues of the journals ACM ToCHI and Human-Computer Interaction. This collection also has more material on methodology and theory (like situated and distributed cognition) than most others.
