Abstract

Computer–human interaction (CHI) [also termed human–computer interaction (HCI)] is concerned with the analysis and design of the interaction between humans and the computer systems they use. A goal of computer–human interaction is to purposefully design aspects of the computing system so that it can be used in an efficient, effective, and error-free manner by people to support their tasks and goals. As such, CHI is concerned not only with the design of usable interfaces between the user and the computer system but also with the provision of appropriate and complete functionality necessary for users to accomplish the tasks they set out to do with the computer system. Thus, computer systems must be designed to be both usable, and useful.

CHI is interdisciplinary in nature, having historical roots and/or current practitioners in the fields of computer science, human factors and ergonomics, psychology, sociology, anthropology, and industrial design the issues and guidelines described here are applicable to design of Web sites and pages as well as more traditional software systems, the guidelines and discussions specific to Web usability can be found in the refernece.

This article describes theoretical perspectives on CHI, presents design issues regarding the computer-human interface, describes individual characteristics of users, summarizes the methods relevant to designers of computer systems, and discusses issues specific to the design of help systems and user documentation.
