Abstract: 
This paper presents the findings of a study on the human perception of static orientation errors in a tracking system, using two different setups leveraging a handheld viewfinder: a classical augmented scenario and an indirect one. By categorizing static orientation errors by scenario and local orientation axis, new insights are found. Our results show that users are much more aware of errors in classical AR scenarios in comparison to indirect AR scenarios. For both scenarios, the users registered roll orientation errors differently from both pitch and yaw orientation errors, and pitch and yaw perception is highly dependent on the scenario.
