That's not norma(n/l)

Interaction error prevention needs to start from a good understanding of the context of an error. One of the central issues in gaze-interaction research is the suppression of the so-called Midas touch: the interface's incorrect evaluation of user gaze as a purposeful interaction command. We conduct a detailed analysis of numerous instances of these events during interactive problem-solving. By developing and applying an annotation scheme we present a taxonomy of the errors and remedial strategies users employ. We present the nuances, richness and development of the user behavior when dealing with the outcomes of the error, and uncover two major coping strategies. The knowledge will be used to design automatic error-prevention mechanisms for gaze-based interaction.
