Scenarios in the Heuristic Evaluation of Mobile Devices: Emphasizing the Context of Use
Varying contexts of use make the usability studies of mobile devices difficult. The existing evaluation methods, such as Heuristic Evaluation (HE), must be redesigned in order to create more awareness of the mobile context. Through the reworking of existing heuristics and use of written use scenarios, there have already been some promising results. In this study the context of use of mobile devices was examined with written scenarios. The main target was to improve the reliability of HE by increasing the number of right predictions and reducing the number of false positives produced by the evaluators. The results seem to differ from those of a previously conducted study as the scenarios did not improve the HE regarding the numbers of false positives or accurate predictions. There is a need for more research regarding the possible benefits of different scenarios and other factors that affect the outcomes of HE.
