An Interface Design Methodology: Scenario Based Design Extended for Diverse Computer User Groups

The purpose of this work is to begin development of a culturally valid interface design process. This process would benefit interface designers and design companies by providing a model that facilitates design for special user populations (e.g., the educationally underserved). Discussion in this paper centers on merging (1) an accepted interface design process in the HCI community, (2) various elicitation methods for determining user needs and (3) noted design considerations for marginalized groups such as the economically/educationally underserved in the United States. The acculturalization model discussed here is an extension of Rosson and Carroll´s (2002) scenario based development (SBD) user-centered interface design approach. In SBD, scenarios are developed and analyzed to assist designers with requirements analysis, system functionality, information presentation, interactions methods, documentation, and the design of the prototypes and the usability evaluations. SBD employs three major phases: analysis, design, and prototype and evaluation
