Description
Summary:Adaptive automation is pivotal for the calibration of trust between automation and its users. This paper presents an exploratory analysis into the use of facial expressions to trust in automation. This was done by analysing facial expressions of distrust and classifying into facial AUs composites, and comparing these to the 6 basic emotions. Results suggests the existence of two prototypical expressions of distrust that can be distinguished from the basic emotions based on AUs combinations. This shows promise into using facial AUs as a means for detecting distrust
