Cognitive load and usability analysis of R-MAP for the people who are blind or visual impaired


The ultimate goal of this work is to understand the confluence of cognitive load and usability studies in evaluating the performance of fully integrated assistive technology solutions. The platform used for this study is called, Reconfigured Mobile Android Phone (R-MAP). The focus of this study is to measure the cognitive load and perform usability analysis and use them as a guide to refine the design and improve the usability of the R-MAP. A "secondary task performance" based procedure for measuring the cognitive load was used to study the R-MAP. The score of the secondary task performance was found to have strong relationship with the cognitive load, usability of the R-MAP and also the differences in performances among various categories of users. © 2011 ACM.
