CAPRIOv2.0: A Context-Aware Unified Indoor-Outdoor Path Recommendation System

摘要

The CAPRIOv2.0 system is the evolution of CAPRIO, our context-aware path recommendation system that has as its primary objectives the minimum outdoor exposure and distance of the recommended path. CAPRIOv2.0 offers enhanced indoor context-awareness in terms of accessibility and congestion. In this demonstration, we exhibit CAPRIOv2.0 and present its novel graph representation that integrates accessibility, congestion, indoor, and outdoor information to discover paths satisfying accessibility, outdoor exposure, and distance constraints of an individual. We further present a new spatial model index, called SMI-tree, which enables CAPRIO v2.0 to quickly forecast the congestion in corridors and hallways. Individuals can interactively engage with the CAPRIOv2.0 GUI using any of their devices to appreciate how our proposed structures and algorithms can provide an alternative context-aware path by combining outdoor, indoor, congestion and accessibility information.Video https://db.cs.pitt.edu/caprio/v2
