Evaluating the User Experience in Interactive Installations: A Case Study

Currently, digital technologies are present in many areas of our lives and are used for various purposes. The ubiquitous technology landscape through ubiquitous and pervasive technologies has brought new forms of interaction. In this context, Human-Computer Interaction (HCI) community has been directing efforts towards its methods. Among the challenges are the types of evaluations commonly performed to improve the quality of systems. In this work, we explored different methods to evaluate the user experience with nine interactive installations developed in a Human-Computer Interaction discipline project. The User Experience evaluation was made using AttrakDiff, which seeks to measure hedonic, pragmatic, and attractiveness qualities in an interaction. The second method was a combination of the Pleasure Framework (its thirteen categories of pleasure) and the Self-Assessment Manikin (SAM) in its Pleasure dimension.. The choice of methods was given by the nature of the interactive installations, equally valuating pragmatic qualities as well as hedonic ones. The results show that triangulation approaches, such as the used in this work, were effective because they brought qualitative aspects of the experience, considering both pragmatic and hedonic aspects of the interaction. Particularly in our case study, artifacts with high hedonic qualities obtained good ratings in the pleasure categories.
