This volume presents the proceedings of the Fourth East-West Conference on Human-Computer Interaction, EWHCI '94, held in St. Petersburg, Russia in August 1994. One of the main objectives of EWHCI is to foster professional and personal contacts between researchers in the former Soviet Union and researchers from the rest of the world. The volume contains revised versions of the 20 best papers selected from the 37 papers accepted for presentation at the conference and covers three basic themes: theoretical and empirical underpinnings of HCI, implemented systems, and the relationship of HCI to other fields. The papers are organized in sections on foundations of HCI, empirical studies and applications, environments, architectures, learning and teaching, and hypertext.
