You studied “Evaluation methods” like Heuristics, Cognition, Questionnaire etc in this course. All these methods apply on web applications during and after development.

Now days all of you are familiar with Mobile web apps that are used only for single task like weather forecasting etc. Keeping in view the context as described above, environment and nature of application (Multi-touch gestures like swipe and pinch), do you think that existed “Evaluation Methods” are sufficient for good results? Justify your point of view in either case with very solid points. Your answer must be precise; no detail is required in paragraph form.



Solution Is Here

Heuristic Evaluation

Heuristic evaluations were introduced by Nielsen and Molich in 1990 in the influential paper "Heuristic Evaluation of User Interfaces" and later assembled as part of a book (Nielsen 1994). A heuristic evaluation involves having an expert review an interface against a set of guidelines or principles. These heuristics provide a template to help uncover problems a user will likely encounter. Nielsen's 10 heuristics are the most popular but there are actually many more.

Cognitive Walkthrough

A cognitive walkthrough is also a usability inspection method like heuristic evaluation but the emphasis is on tasks. The idea is basically to identify users' goals, how they attempt them in the interface, then meticulously identify problems users would have as they learn to use an interface. The method was also introduced at the same conference as Heuristic Evaluation (Lewis et al 1990). The cognitive walkthrough was an extension of earlier work by Polson and Lewis (1990)
