Compared to the online interaction behavior of other users, little is known about the difficulties dyslexic Web users encounter online. This paper reviews existing literature at the intersection of dyslexia and accessibility research to determine what useful knowledge exists regarding this important and relatively large group of users. This review uncovers that, although there are few published usability tests with dyslexic users, there is a considerable body of knowledge on dyslexia as well as many design guidelines for authoring dyslexic-accessible interfaces. Through a comparison of existing accessibility guidelines for dyslexic and non-dyslexic users and discussion of the plain language movement, it is argued that dyslexic-accessible practices may redress difficulties encountered by all Internet users. This conclusion suggests that usability testing yielding a clearer profile of the dyslexic user would further inform the practice of universal design, but also that enough knowledge is already available to allow doing more to increase accessibility for dyslexic Internet users.

Monk, Donald L., Swierenga, Sarah J. and Lincoln, Janet E. (1992): Developing Behavioral Phenomena Test Benches. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1106-1109.
A research and development program is underway to produce an innovative design support system for crew station designers. Known as the Performance Visualization Subsystem of the Computer Aided Systems Human Engineering Program (CASHE: PVS), this design tool will have data visualization and prototyping capabilities that will enable designers to "go beyond" the human perception and performance information available in the PVS database. Interactive software modules (called test benches) are being developed to allow designers to explore behavioral phenomena under different stimulus and response conditions. The objective of this paper is to describe a method we have used to translate the information in the PVS database into test bench specifications for software development. The basic approach in test bench design is: 1) to rely on standardized tasks and conditions where possible and 2) to provide designers with pedagogical illustrations of perceptual and performance effects. The procedures used in developing test bench specifications included identifying good candidates for test bench simulations, prioritizing the set of proposed test benches according to selection criteria developed by the design team, and recruiting subject matter experts to generate test bench specifications that will be used by the software engineers to implement the test bench code. The result of this effort will be a commercially available software product that will help crew station designers more effectively understand and apply human factors principles in the design process.

Over the past decade, a multi-phased project supported by agencies of the Department of Defense, FAA, and NATO has been underway to understand and remediate problems in the transitioning of ergonomic research to system design applications. Efforts to enhance the usability of ergonomic data in system design have resulted in the present R&D project, which is concerned with developing a multi-media ergonomics database on CD-ROM. The Computer Aided Systems Human Engineering (CASHE) system, Version 1.0, will contain the Boff and Lincoln (1988) Engineering Data Compendium, MIL-STD-1472D and the Perception&Performance Prototyper. The Perception&Performance Prototyper will allow the user to experience and manipulate the technical data found in the Compendium and MIL-STD-1472D. The CASHE tool will also include specialized data retrieval, scaling, and analysis capabilities as well as state-of-the-art in information retrieval, browsing, and navigation.

An important issue in implementing Rapid Communication (RAPCOM) display technology is the manner in which information is coded within a given display sequence. This study compared performance on a search task for four single coding strategies as well as four redundant code combinations at five presentation rates. Results indicated significant differences in accuracy and reaction time for task performance using single and redundant codes at various frame durations. These findings helped to identify several potential coding formats that can be utilized in real-world settings.

Swierenga, Sarah J. (1990): Menuing and Scrolling as Alternative Information Access Techniques. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 356-359.
An experiment was conducted to evaluate menuing and scrolling as alternative information access techniques when a touch-sensitive input device was used to interact with the system. A hierarchical menu structure and three scrolling methods, line-by-line, half-screen, and full-screen, were tested. Level of goal word familiarity (familiar and unfamiliar) and window display size (12 or 24 lines displayed on the screen) were also examined. The task consisted of using a touch tablet to locate a target goal word with one of the four access methods. Members of a single set of 64 words, 32 familiar and 32 unfamiliar, served as goal words in all conditions. Performance data (total time to complete the task) were collected from 48 subjects. Access method and window size were between-subject variables. Each subject received both word familiarity levels. Results of an analysis of variance on mean total task time (MTIME) revealed a significant access method by word familiarity interaction. Separate analyses of variance were conducted on MTIME for familiar and unfamiliar goal word sets. When the goal word was familiar, menuing was fastest, followed by line-by-line, full-screen, and half-screen scrolling. For unfamiliar goal words, line-by-line scrolling was fastest, followed by full-screen, half-screen, and menuing. The effect of window size was not significant. The findings of this study suggest that the operator's familiarity with the information being searched is important when deciding upon an access method.
