Abstract

We present RagRug, an open-source toolkit for situated analytics. The , abilities of RagRug go beyond previous immersiveanalytics toolkits by , focusing on specific requirements emerging when using augmented , reality (AR) rather than virtual reality. RagRugcombines state of the , art visual encoding capabilities with a comprehensive physical-virtual , model, which lets application developerssystematically describe the , physical objects in the real world and their role in AR. We connect AR , visualizations with data streams fromthe Internet of Things using , distributed dataflow. To this end, we use reactive programming , patterns so that visualizations becomecontext-aware, i.e., they adapt , to events coming in from the environment. The resulting authoring , system is low-code; it emphasisesdescribing the physical and the , virtual world and the dataflow between the elements contained therein. , We describe the technicaldesign and implementation of RagRug, and , report on five example applications illustrating the toolkit’s , abilities.
