"Human Augmented Mapping"

Over the last few decades we have seen tremendous progress on robotics, artificial intelligence and computer perception. Yet, the integrated systems for assistance to the average citizen have not emerged. The emergence of methods for effective mapping, robust human robot interaction and methods for learning with real-world data have enabled a new generation of systems that can be deployed for use in realistic environments. In this presentation we will present examples of how current research on visual perception and mappping can be integrated with methods for recognition and dialog systems to enable a new generation of systems that enable mapping of environments and which fuse semantic, topological and metric information into a coherent representation. The system uses a dialog system for user and system driven acquisition of semantic information. The metric mapping is generated using a graph based approach to localization and mapping. Topological information is derived from recognition of key structures - the scene gist - and through geometric reasoning. The human augmented mapping has been tested through numerous experiments and the training utilizes a data-set that encodes environmental variations over a 6 month period.
