Book excerpt: Human Computer Interaction (HCI) is concerned with every aspect of the relationship between computers and people (individuals, groups and society). The annual meeting of the British Computer Society's HCI group is recognised as one of the main venues for discussing recent trends and issues. This volume contains refereed papers and reports at the 1993 meeting. A broad range of HCI related topics are covered, including user interface design, user modelling, tools, hypertext, CSCW, and programming. Both research and commercial perspectives are considered, making the book essential for all researchers, designers and manufacturers who need to keep abreast of developments in HCI.
