A questionnaire was used to investigate what users of medical technology regard as the largest component of usability.
The results also demonstrate that interface features – key components of the usability of a Web site – influenced the three cognitive appraisals illustrated in the research model.
Despite the growing attention given to Web usability, little is understood as to what Web design features contribute to Web users' attitude, a major component of the usability of a Web site.
For the components of impact and usability, a metric called relevance was generated, which establishes the importance of adoption.
This chapter covers usability issues in the production process, Web site engineering techniques, engineering Web site components, and usability of web technologies.
Erickson [9] proposed usability scenarios for each different level of tailoring: customization (setting parameters), composition (link between existing components), expansion (creation of a new component) and extension (insertion of new code) and compiled a set of usability and design patterns that could support design decisions and implementation.
Beauty is merely one component of design, like usability, speed, cost, and time.
Only by defining the abstract concept of "usability" in terms of these more precise and measurable components one can arrive at engineering discipline where usability is not just argued about but is systematically approached, improved, and evaluated or possibly measured.
Two rounds of usability testing resulted in additional versions that included new features such as added intervention components, topic areas, and a community networking function.
