Abstract:
The work presented here is born of our extensive experience evaluating the usability of user interfaces and observing that some traditional methods need to be updated and improved. Here, we put the focus on the Heuristic Evaluation (HE) technique. It is one of the important topics in Human-Computer Interaction (HCI) when talking about usability evaluation. Different research works have been discussing the effectiveness of the current HE, but it is important to improve its effectiveness. A substantial improvement is presented, consisting of: (i) a new list of principles for evaluating any interface, (ii) a set of specific questions to be answered when analysing every principle, (iii) an easy rating scale for each question, and finally, (iv) a method to obtain a quantitative value, called the Usability Percentage. It gives a numeric idea about how usable the evaluated interface is. An experiment by a group of experts helped to validate the implications of the proposed solution.
