How Wrong Can You Be: Perception of Static Orientation Errors in Mixed Reality How Wrong Can You Be: Perception of Static Orientation Errors in Mixed Reality Jacob B. Madsen∗ Rasmus Stenholt† Dept. of Architecture, Design, and Media Techonology Aalborg University, Denmark ABSTRACT Tracking technologies are becoming an affordable commodity due to the wide use in mobile devices today. However, all tracking technologies available in commodity hardware is error prone due to problems such as drift, latency and jitter. The current understand- ing of human perception of static tracking errors is limited. This information about human perception might be useful in designing tracking systems for the display of AR and VR scenarios on com- modity hardware. In this paper we present the findings of a study on the human perception of static orientation errors in a tracking sys- tem, using two different setups leveraging a handheld viewfinder: a classical augmented scenario and an indirect augmented one. By categorizing static orientation errors by scenario and local orienta- tion axis, new insights into the users’ ability to register orientational errors in the system are found. Our results show that users are much more aware of errors in classical AR scenarios in comparison to in- direct 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. However, the users performance ranking for orientational errors in AR scenarios was unexpected. Keywords: Augmented reality, perception, tracking errors.
