TL;DR: A user interface is that portion of an interactive computer system that communicates with the user as mentioned in this paper. User interfaces include any aspect of the system that is visible to the user, such as a keyboard, mouse, or display.
Abstract: A user interface is that portion of an interactive computer system that communicates with the user. Design of the user interface includes any aspect of the system that is visible to the user. Once, all computer users were specialists in computing, and interfaces consisted of jumper wires in patch boards, punched cards (q.v.) prepared offline, and batch printouts. Today a wide range of nonspecialists use computers, and keyboards, mice, and graphical displays are the most common interface hardware. The user interface is becoming a larger and larger portion of the software in a computer system--and a more important portion, as broader groups of people use computers. As computers become more powerful, the critical bottleneck in applying computer-based systems to solve problems is more often in the user interface rather than in the computer hardware or software.

TL;DR: This chapter discusses the application of eye movements to user interfaces, both for analyzing interfaces (measuring usability) and as an actual control medium within a human–computer dialogue.
Abstract: Publisher Summary This chapter discusses the application of eye movements to user interfaces, both for analyzing interfaces (measuring usability) and as an actual control medium within a human–computer dialogue. For usability analysis, the user's eye movements are recorded during system use and later analyzed retrospectively; however, the eye movements do not affect the interface in real time. As a direct control medium, the eye movements are obtained and used in real time as an input to the user–computer dialogue. The eye movements might be the sole input, typically for disabled users or hands-busy applications, or might be used as one of several inputs, combining with mouse, keyboard, sensors, or other devices. From the perspective of mainstream eye-movement research, human–computer interaction, together with related work in the broader field of communications and media research, appears as a new and very promising area of applied work. Both basic and applied work can profit from integration within a unified field of eye­-movement research. Application of eye tracking in human–computer interaction remains a very promising approach; its technological and market barriers are finally being reduced.

TL;DR: In this paper, the usefulness of eye movements as a fast and convenient auxiliary user-to-computer communication mode was investigated, and the first eye movement-based interaction techniques were devised and implemented in a laboratory.
Abstract: In seeking hitherto-unused methods by which users and computers can comrnumcate, we investigate the usefulness of eye movements as a fast and convenient auxiliary user-to-computer communication mode. The barrier to exploiting this medium has not been eye-tracking technology but the study of interaction techniques that incorporate eye movements mto the usercomputer dialogue in a natural and unobtrusive way This paper discusses some of the human factors and technical considerations that arise in trying to use eye movements as an input medium, describes our approach and the first eye movement-based interaction techniques that we have devised and implemented in our laboratory, and reports our experiences and observa tions on them.

TL;DR: It is believed that viewing interaction through the lens of RBI provides insights for design and uncovers gaps or opportunities for future research.
Abstract: We are in the midst of an explosion of emerging human-computer interaction techniques that redefine our understanding of both computers and interaction. We propose the notion of Reality-Based Interaction (RBI) as a unifying concept that ties together a large subset of these emerging interaction styles. Based on this concept of RBI, we provide a framework that can be used to understand, compare, and relate current paths of recent HCI research as well as to analyze specific interaction designs. We believe that viewing interaction through the lens of RBI provides insights for design and uncovers gaps or opportunities for future research.

TL;DR: This guide to the methods of usability engineering provides cost-effective methods that will help developers improve their user interfaces immediately and shows you how to avoid the four most frequently listed reasons for delay in software projects.
Abstract: From the Publisher: Written by the author of the best-selling HyperText & HyperMedia, this book provides an excellent guide to the methods of usability engineering. Special features: emphasizes cost-effective methods that will help developers improve their user interfaces immediately, shows you how to avoid the four most frequently listed reasons for delay in software projects, provides step-by-step information about which methods to use at various stages during the development life cycle, and offers information on the unique issues relating to informational usability. You do not need to have previous knowledge of usability to implement the methods provided, yet all of the latest research is covered.

TL;DR: It is intended to demonstrate here that statecharts counter many of the objections raised against conventional state diagrams, and thus appear to render specification by diagrams an attractive and plausible approach.

TL;DR: The basic theme of the review is that eye movement data reflect moment-to-moment cognitive processes in the various tasks examined.
Abstract: Recent studies of eye movements in reading and other information processing tasks, such as music reading, typing, visual search, and scene perception, are reviewed. The major emphasis of the review is on reading as a specific example of cognitive processing. Basic topics discussed with respect to reading are (a) the characteristics of eye movements, (b) the perceptual span, (c) integration of information across saccades, (d) eye movement control, and (e) individual differences (including dyslexia). Similar topics are discussed with respect to the other tasks examined. The basic theme of the review is that eye movement data reflect moment-to-moment cognitive processes in the various tasks examined. Theoretical and practical considerations concerning the use of eye movement data are also discussed.
