Calls for interaction: The more the better? user experience of 3D carousel and additional interaction techniques

Abstract

We perform a user study to investigate the psychological consequences of adding interaction techniques to the interface. In a between-subjects experiment (N = 143), we explore how (i) variations in sheer number of interaction techniques and (ii) addition of a novel technique, i.e., 3D carousel, influence the volume of users' actions, their memory, perceptions of interactivity, as well as their attitudes and behaviors toward a website. Power usage is examined as a potential moderator. First-cut findings from self-reports and log data indicate that the 3D carousel feature has a strong impact on user experience, both positive and negative. It also moderates the curvilinear effect of adding traditional interaction techniques to the interface. © 2011 IFIP International Federation for Information Processing.
