ABSTRACT
Accessibility analysis tools can be used to better understand the nature and extent of access barriers related to medical devices so better designs can be implemented. Expert comparisons of the utility of three tools for determining biomechanical accessibility are discussed, including (1) Mobile Usability Lab (MU-Lab) Protocol Manager (PM) questionnaires, (2) interactive MU-Lab barrier analyses using Multimedia Video Task Analysis (MVTA) software, and (3) Medical Equipment Device-Accessibility and Universal Design Information Tool (MED-AUDIT) software algorithm for estimating accessibility. MVTA was most often rated the highest of all the tools. The strengths, weaknesses, advantages, and disadvantages were documented for each tool.
