Evaluating user's emotional experience in HCI: The PhysiOBS approach

Abstract

As computing is changing parameters, apart from effectiveness and efficiency in human-computer interaction, such as emotion have become more relevant than before. In this paper, a new tool-based evaluation approach of user's emotional experience during human-computer interaction is presented. The proposed approach combines user's physiological signals, observation data and self-reported data in an innovative tool (PhysiOBS) that allows continuous and multiple emotional states analysis. To the best of our knowledge, such an approach that effectively combines all these user-generated data in the context of user's emotional experience evaluation does not exist. Results from a preliminary evaluation study of the tool were rather encouraging revealing that the proposed approach can provide valuable insights to user experience practitioners. © 2014 Springer International Publishing.
