This paper presents low-cost experiments for a control systems laboratory module that is worth one and a third credits. The experiments are organized around the microcontroller-based control of a permanent magnet dc motor. The experimental setups were built in-house. Except for the operating system, the software used is primarily freeware or free…

With the rise of Web pages providing interactive support for problem-solving or providing large amounts of information on which a person is expected to act, designers and writers need to consider how a person interacts with increasingly complex information-rich environments and how they intend to use the information. This article examines some of…

Discusses elements involved in the visual design of the computer-learner interface. Topics discussed include the need for consistency in screen layout; information representation, including accuracy in images and visual cuing strategies; and menu selection interfaces, or command representations, including their placement on the screen. (11…

The development of safety-critical systems (aircraft cockpits and reactor control rooms) is qualitatively different from that of other interactive systems. These differences impose burdens on design teams that must ensure the development of human-machine interfaces. Analyzes strengths and weaknesses of formal methods for the design of user…

This paper explores interactivity, and considers what should be done to create a mass market for interactive media. It is suggested that one way to do so is to examine the video game phenomenon, and a model of interactivity is proposed. The model, a "home interactive theater," would involve interaction in the telling of a story, with the…

The ability to design and build sophisticated computer-based information systems (CIS) has progressed rapidly; however, the ability to implement them has not kept pace. These implementation problems can be solved by embedding CIS design with the socio-technical systems design approach. (Author/MLW)

This paper summarizes the general issues discussed at the September 1986 conference of the Apple Education Advisory Council and during the Advisory Council's deliberations about the future. The general issues are categorized within four topics--technical considerations, people considerations, human/technology interface considerations, and network…

Identifies human factor issues involved in the student-computer interface in computer assisted instruction and makes specific recommendations for screen design. Factors considered include simplicity, spaciousness, relevance, standardization, changing display screen contents, color coding, shape and size coding, and brightness coding. (Author/LRW)

Explores the pros and cons of various computer menu layouts to be used with computer-assisted learning media. The importance of designing a screen menu that takes into consideration the student's learning style is emphasized. (Author/LRW)

Provides overview of design requirements for transparent information retrieval (implies that user sees through complexity of retrieval activities sequence). Highlights include need for transparent systems; history of transparent retrieval research; information retrieval functions (automated converters, routers, selectors, evaluators/analyzers);…

Describes an interactive data retrieval system which was designed and implemented for casual users and which incorporates a user-friendly interface, aids to train beginners in use of the system, versatility in output, and error recovery protocols. A 14-item reference list and two figures illustrating system operation and output are included. (JL)

Assesses the appropriateness of GUIs (graphical user interfaces), more specifically Windows-based interfaces for CD-ROM. An evaluation model is described that was developed to carry out an expert evaluation of the interfaces of seven CD-ROM products. Results are discussed in light of HCI (human-computer interaction) usability criteria and design…

Discusses basic principles of human-computer interface design that will be helpful to librarians involved in designing effective OPAC (Online Public Access Catalog) screens. Highlights include physical features; general principles; menu screens; commands; inquiry screens; messages, including help screens; and organizational considerations,…

Discussion of virtual reality (VR) focuses on research and development being carried out at NYNEX to solve business problems. Component technologies are described; design decisions are considered, including interactivity, connectivity, and locus of control; potential perils of VR are discussed, including user dissociation; and areas of promise are…

Addresses the problems of unsuitable physical layout of the visual display terminal, keyboard, and document holder and improperly selected office furniture by discussing a group of office products dubbed "computer furniture," i.e., terminal tables and furniture for peripherals. Purchasing advice is included. (EJS)
