102. Obtención empírica y no empírica de un conjunto específico de heurísticas sobre experiencia de usuario para sistemas de información - López, José; Hernández, Jorge; Rangel, Nelson; Rodríguez, Mario; Butron, Martha; Jasso, Omar
The set of ten heuristics proposed by J. Nielsen is oriented to measure the user experience (UX) in general. However, when dealing with the particular case of an information system (IS), these heuristics cannot identify all the bad situations, or problems, related with the UX. This paper proposes the inclusion of three heuristics (identity, accessibility, y attractivity) to those proposed by J. Nielsen, in order to identify better the problems about by the UX in IS. The new set of heuristics was tested over a case of study composed by 54 ISs, 141 users of them, and a questionnaire applied to the users. Based on Usability recommendations...
