kARbon: a collaborative MR web application for communicationsupport in construction scenarios

kARbon demonstrates a web-based mixed reality (MR) support and collaboration tool for a wide range of construction planning and supervising scenarios. We describe how the construction process can be supported for locally distributed workers, experts and decision makers by leveraging MR methods in combination with effective and pure web-based collaboration, interaction and presentation concepts. kARbon therefore combines classical CAD planning data with photo collections representing temporal snapshots of the associated construction site in a precise MR scene. We focus on our collaborative use case and describe how involved people in different locations and on different device types can collaborate and interact through our tool based on the power of modern web standards.
