Human – Computer Interaction (HCI) should be a basic part of the formative process of all computer science professionals. Usability and User Experience (UX) were (re)defined by many authors and well recognized standards. UX is usually considered as an extension of usability. To move from usability to UX seems to be a tendency lately. Forming usability/UX evaluators is a challenging task. Practice is usually more appealing and persuasive than theory. The paper presents a study on the perception of (novice) evaluators over generic and specific usability heuristics.
