Toward Engineering Design Principles for HCI

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 ele
