[DC] Annotation in Asynchronous Collaborative Immersive Analytic Environments using Augmented Reality

Immersive Analytics (IA) and Augmented Reality (AR) head-mounted displays provide a different paradigm for people to analyze multidimensional data and externalize their thoughts by utilizing the stereoscopic nature of headsets. However, using annotation in IA-AR is challenging and not well-understood. In addition, IA collaborative environments add another complexity level for users operating on complex visualized datasets. Current AR systems focus mainly on synchronized collaboration, while asynchronous collaboration has remained unexplored. This project investigates annotation in IA for asynchronous collaborative environments. We present our research studies on virtual annotation types and introduce a new filtering annotation technique for IA.
