ABSTRACT
This chapter describes the Mobile Usability Lab (MU-Lab), a structured tool for performing systematic analysis of the accessibility of a targeted medical product or class of products. MU-Lab helps guide a research team through the assessment process. The system consists of Web-based Protocol Manager (PM) software, plus hardware that can be transported within a customized suitcase. The process starts with preliminary steps such as an initial heuristic analysis guided by universal design principles, plus the important step of determining an appropriate population of users with disabilities and documenting their abilities. This is followed by video-based usability data collection sessions that also include a structured postactivity analysis questionnaire. Data analysis includes a special focus on task analysis of events related to accessibility barriers.
