In various papers we argued that (optical see-through) AR realized with smart glasses will become an everpresent wearable technology. It is against this background that we want to look at what is and what is not experienced by AR users as imperfect, inappropriate, incongruent, improbable, or impossible. All these concepts are related to “presence”,...
