Augmented Reality Indoor-Outdoor Navigation Through a Campus Digital Twin

Geolocated services can play a significant role in enhancing user experiences, in complex environments like complex campuses, for onboarding new employees and students and guiding tourists and visitors. This motivation is driving research and development in the area of geolocated augmented reality (AR) navigation but the field is still quite young. CampusGo is a software platform designed to provide a coherent suite of services to enable the development of AR-enabled, smart-campus applications, including (i) integration of a variety of multimodal data about the campus, such as building architectural diagrams and 3D models of buildings, people's profiles, offices and labs, landmarks and events; (ii) indoor and outdoor path-planning services; (iii) real-time navigation support; and (iv) engaging web and mobile front ends. In this paper, we present the overall system architecture and describe our early experience with deploying and beta-testing CampusGo on a university campus.
