The role and design of screen images in software documentation

Abstract Software documentation for the novice user typically must try to achieve at least three goals: to support basic knowledge and skills development; to prevent or support the handling of mistakes, and to support the joint handling of manual, input device and screen. This paper concentrates on the latter goal. Novice users often experience split‐attention problem due to the need to (almost) simultaneously attend to different media. Existing research indicates that split‐attention problems can be prevented or reduced by the presence of screen images in the manual. Research is yet unclear about the optimal design of these pictures. This study examines three design styles. Forty‐eight novice users received one of the three manual based on these styles. The manuals were an introduction to Windows 95. The users of the most successful manual needed 25% less training time and had a 60% better retention. The most important characteristics of the design style of this manual were its use of full screen images (instead of partial ones) and a two‐column lay‐out in which the instructions and screen images were presented side‐by‐side in a left‐to‐right reading order. The discussion focuses on the tension that exists between theory and practice. Special attention is given to the contributions of a taxonomy of screen images and cognitive load theory.     

Stress training and simulator complexity: why sometimes more is less

Through repeated practice under conditions similar to those in real-world settings, simulator training prepares an individual to maintain effective performance under stressful work conditions. Interfaces offering high fidelity and immersion can more closely reproduce real-world experiences and are generally believed to result in better learning outcomes. However, absolute fidelity in stress training is not critical for skills to be transferable. The present study compared the performance outcomes achieved by trainees using two different simulator types to complete a training program aimed at improving decision-making skills. The purpose of this research was to assess both the overall level of training effectiveness and to determine whether performance levels were influenced when high (160 degree curved wide screen) versus low fidelity (small cab-based flat screen) simulator types were in use. Sixty-three train drivers drove for 40 min on a simulated track on which they encountered four major high stress driving events. One year later, 42 of the original drivers returned and repeated the training scenario a second and third time. Results revealed trainees using the lower fidelity flat screen simulator made fewer errors in both years than trainees using the high fidelity curved screen simulator. The implications of these results are discussed.

The integration of theory and practice in teaching designing for the screen

Future typographic and graphic designers will need to be able to design for a range of media, both to secure their role and to provide the necessary design expertise in technological environments. This paper proposes an approach to teaching which introduces theoretical issues within a practical design project to encourage the development of general concepts that can be transferred to different technologies. A specific project on designing for the screen is described, which is taught as part of a BA degree in Typography & Graphic Communication. In the context of this project, reasons for introducing theory are proposed, examples of the nature of the theory are given, and the methods used to introduce material are illustrated. A detailed account of one student's implementation of this project is used to demonstrate how theoretical issues can provide direction in a design task. However, careful consideration needs to be given to how theory and practice are integrated to encourage students to look beyond the short-term benefits of specific training to the development of more general knowledge.     

Designing screens for people to use easily

The use of interactive computer systems is expanding rapidly. In many applications users can communicate directly with computer-based systems through an interactive dialogue at a display terminal. However, this direct form of communication has created problems. Whereas early users of on-line systems were skilled computer professionals, today's users may have little or no training in computer technology. How then does this group communicate effectively with a computer systems?

The answer is that many users communicate only with considerable difficulty. The result is that the effectiveness of many systems is very much less than expected. The reason for this is simple: these systems are not very good at communicating with their users.

The most common communications bridge between a person and a computer system is a display screen. A well-designed screen format can enhance user productivity, eliminate or reduce user input errors, and promote end user satisfaction. A poorly designed screen has the opposite effect: it will decrease human processing speed, provoke user mistakes, and complicate computer operations.

Screen design requires the same care as designing the overall application. It employs the same techniques as planning and preparing good user documents. Screens, like documents, must be easy to understand and easy to use. To achieve these objectives, screen designers must make good choices regarding three ease-of-use parameters: format; screen content and layout; and style. This paper describes how standards may be established for each of these parameters in a proposed application or system. Futher, an interactive tutorial computer program has been developed (using Bricklin's DEMO program) which may be used to illustrate the application of these standards.
