Human–computer interaction: psychology as a science of design

Abstract

Human–computer interaction (HCI) is the area of intersection between psychology and the social sciences, on the one hand, and computer science and technology, on the other. HCI researchers analyse and design-specific user-interface technologies (e.g. three-dimensional pointing devices, interactive video). They study and improve the processes of technology development (e.g. usability evaluation, design rationale). They develop and evaluate new applications of technology (e.g. computer conferencing, software design environments). Through the past two decades, HCI has progressively integrated its scientific concerns with the engineering goal of improving theusabilityof computer systems and applications, thus establishing a body of technical knowledge and methodology. HCI continues to provide a challenging test domain for applying and developing psychology and social science in the context of technology development and use.
