Title
Interaction Under Pressure: Increased Mental Workload Makes Issues of Intuitive Interaction Visible.
Abstract
Intuitive interaction has become a determining factor for the success of software. This paper contributes to this area of research by describing a novel method for evaluating intuitive interaction as increased mental workload in a dual-task paradigm. During a usability test, mental workload can be measured by analysing the timing of concurrent rhythmic foot tapping. Based on deviations from an individual baseline the method allows to point out the exact moments of increased workload, i.e. these moments where the interaction was likely non-intuitive. In formative usability tests, evaluators can use this information when conducting retrospective interviews to discuss the underlying intuitive-use problems and possible solutions. In contrast to other methods for evaluating intuitive interaction, which are often based on detailed user observations, the proposed method may yield a cost-effective and easily applicable alternative to conduct summative and formative evaluations of intuitive interaction.
