Using Interaction Design to Improve Usability of a PHR User Interface Based on Visual Elements
Stefano Forti, Barbara Purin, Claudio Eccher · IGI Global eBooks · 2009
This chapter presents a case study of using interaction design methods for exploring and testing usability and user experience of a Personal Health Record (PHR) user interface based on visual and graphical elements. To identify problems and improve the design of PHR user interface we conducted two taskoriented usability testing based on the think-aloud technique for observing users during their interaction with a high-fidelity PHR prototype, and questionnaires and semistructured interviews for measuring user satisfaction. Our study demonstrates that a user-centered approach to interaction design involving the final users in an iterative design-evaluation process is important for exploring innovative user interfaces and for identification of problems in the early stages of the development cycle of a PHR.
