Popular Performance Metrics for Evaluation of Interaction in Virtual and Augmented Reality

Augmented and Virtual Reality applications provide environments in which users can immerse themselves in a fully or partially virtual world and interact with virtual objects or user interfaces. User-based, formal evaluation is needed to objectively compare interaction techniques, and find their value in different use cases, and user performance metrics are the key to being able to compare those techniques in a fair and effective manner. In this paper we explore evaluation principles used for or developed explicitly for virtual environments, and survey quality metrics, based on 15 current, important publications on interaction techniques for virtual environments. We check, categorize and analyze the formal user studies, and establish and present baseline performance metrics used for evaluation on interaction techniques in VR and AR.
