To support performance for an international audience of computer users, designers need to examine key elements of performance in relation to the design of systems. Discussion focuses on planning ahead for an international audience and preparing a design that keeps the performer, the process, and the information connected, resulting in optimal…

Describes an experiment in which presentation size and text length is varied in a HyperCard application. Students performed a fact-retrieval task from a reference handbook. No interaction is found between these two independent variables. Performance is significantly better for the longer texts, but no significant difference is found for the two…

Focuses on the pre-design questions that a Web site designer and client need to address. Discusses the why, who, what, where, and when phases of the Web site design process. Includes a Web Site Development Form to guide site designs through the first two stages of Web site development: specification and design. (AEF)
