A Context-Aware Adaptation System for Spatial Augmented Reality

From an HCI point of view Augmented Reality (AR) displays have a very specific characteristic. The shown information consists of a virtual and a nearly uncontrollable and cluttering real part. Thus, AR visualizations can be ambiguous, imprecise, or difficult to understand. To avoid this, the presented project shows a systematic method for adapting AR visualizations to the user's needs and perceptual properties. Therefore, we firstly reused and extended established 2D visualization models with AR specific visualization parameters and secondly incorporated known AR specific perception facts to set up an AR smart home control system in a kitchen. The control system involves spatial AR displays (sAR) and makes use of context information like current user tasks or the user's position. The goal is to provide a generic approach of displaying unambiguous AR information at the right time and location without overwhelming the user.
