This is the first of two books concerned with engineering design principles for Human-Computer Interaction-Engineering Design Principles (HCI-EDPs). The book presents the background for the companion volume. The background is divided into three parts and comprises—"HCI for EDPs," "HCI Design Knowledge for EDPs," and "HCI-EDPs—A Way Forward for HCI Design Knowledge." The companion volume reports in full the acquisition of initial HCI-EDPs in the domains of domestic energy planning and control and business-to-consumer electronic commerce (Long, Cummaford, and Stork, 2022, in press).

This is the second of two books by the authors about engineering design principles for human-computer interaction (HCI-EDPs). The books report research that takes an HCI engineering discipline approach to acquiring initial such principles. Together, they identify best-practice HCI design knowledge for acquiring HCI-EDPs. This book specifically reports two case studies of the acquisition of initial such principles in the domains of domestic energy planning and control and business-to-consumer electronic commerce. The book begins by summarising the earlier volume, sufficient for readers to...
