Abstract:
With the falling price of the technology and the growing trend of cluster display-walls, User Experience (UX) becomes a topic to be taken into account with this new kind of systems. In this context, we present a study of a specific cluster display-wall, named Liquid Galaxy and developed by Google, that covers the three main aspects of usability: effectiveness, efficiency and satisfaction. The study was done by means of a set of tasks that users completed during UX tests, with post-task and post-tests questionnaires, while the system performance was measured. The results show positive feelings from users while using the system. In addition, we relate both system performance and user behavior to estimate whether the system will perform satisfactorily for users. According to our observations, we can see that, in general, there is an intrinsic relationship between the goodness of feelings and the quality of the performance metrics. This relationship can facilitate the inclusion of cluster display-wall systems in a broad range of scenarios with right levels of UX just by analyzing their computational characteristics.
