Do Scale Type Techniques Identify Problems that Affect User eXperience? User Experience Evaluation of a Mobile Application (S)

User experience (UX) is a quality aspect of an application that considers the emotions evoked by the system. There are several types of UX evaluation methods, such as scales, interviews, user monitoring, among others methods. However, there is still not enough information regarding if and in which contexts these methods are more suitable. This paper focuses on finding more information about the feasibility of applying scaletype methods for the UX evaluation in interactive systems. Thus, we carried out a UX evaluation on the Edmodo educational mobile application employing two scale-type methods: AttrakDiff and Hedonic Utility Scale. These methods were chosen after a selection process applying inclusion and exclusion criteria. The results indicate that it is possible to evaluate the quality of an application at a low cost. However, it is necessary to adapt these methods to provide a more complete report of the UX, allowing users to subjectively report their experiences and, consequently, identify the issues that affected the UX.
