Indoor Information Systems (IIS) have witnessed significant growth over the past decade, driven by the fact that 90% of our activities are carried out in indoor spaces. As a result, new research paradigms in constituent technologies have emerged, ranging from data-driven localization algorithms, to data privacy handling schemes, and indoor data management operators. Towards this direction, successful launching of popular applications relied on stored indoor spatial models fusing sensor information, exploiting sensor prevalence in smartphone devices and wireless connectivity pervasiveness, in light of the big data era and accompanying technologies. This workshop aims to discuss current trends and highlight future directions on both established and potentially transforming Algorithms for Indoor Architectures and Systems.

The workshop will be organized in a manner that fosters interaction and exchange of ideas among the participants. Besides regular papers, we will also consider vision, retrospective and work-in-progress papers that have the potential to stimulate debate on existing solutions or open challenges. We additionally plan to accept a limited number of demonstration papers where researchers and technologists will have the opportunity to describe an innovative system or tool in the area of data management for mobile and wireless access. We discourage the submission of incremental papers. This year's program is also expected to feature a keynote speech and a panel discussion on newly-emerging or controversial topics.

The topics of interest include, but are not limited to:

  • Indoor positioning using different technologies (e.g., Cellular 3G/4G/5G and beyond, Wi-Fi, UWB, RFID, Magnetic, Pedestrian Dead-Reckoning, Vision, Hybrid, etc.)
  • Contact tracing and social distancing for pandemics
  • 2D and 3D operators for localization and analytics
  • Modeling and representation of indoor spaces
  • Indoor GIS integration efforts (IndoorOSM, IndoorGML)
  • Storage, processing and indexing operators for indoor data
  • Collaborative positioning and crowdsourcing
  • Indoor analytics and indoor decision support systems
  • Visual analytics of indoor data
  • Big-data processing of indoor data
  • Privacy issues with indoor technologies
  • Human mobility data acquisition, handling, and analysis in indoor spaces
  • Data quality and uncertainty issues study on indoor mobility data
  • Discovery of indoor mobility patterns
  • Theoretic and/or empirical indoor modelling issues
  • Semantic knowledge harvesting and ontologies for indoor data
  • Recommender Systems for indoor data (e.g., POIs, services)
  • Real-time analysis of data generated in indoor spaces (audio, video, text)
  • Social behaviour analysis on indoor mobility data
  • Machine learning on indoor data
  • Security and Privacy in indoor mobile systems
  • Robotics and Drones for logistics operations in indoor spaces
  • Indoor Case Studies (e.g., Healthcare, Airports, Campuses)
  • Interactive media technologies to indoor (Augmented/Virtual/Mixed Reality)
  • Offline and Hybrid Online/Offline Navigation and Context Awareness
  • Mapmatching Algorithms and Systems
  • Out-of-the-box application domains for indoor (blockchain, AI, IoT)
