LOADS: LiDAR-based Privacy-Preserving Queue Monitoring and Analysis

Long queues in retail and public environments can frustrate customers and negatively impact user experiences. Traditional camera-based monitoring systems are effective in analyzing queues, however, the potential for identification raises privacy …

Efficient Scheduling of Smart Building Energy Systems Using AI Planning

Buildings account for a significant share of global energy consumption, with Heating, Ventilation, and Air Conditioning (HVAC) systems being responsible for up to 60% of a building's energy usage. For this purpose, existing scheduling and control …

Co-zyBench

Heating, Ventilation, and Air Conditioning (HVAC) systems account for 40% to 50% of energy usage in commercial buildings, so controlling them while preserving occupants' comfort matters. State-of-the-art solutions use pervasive systems with sensors or smart devices to gauge individual thermal sensations, but assessing those methods is hard: real-world experiments are expensive, limited in access, and often overlook occupant and regional diversity. Co-zyBench is a benchmark tool that takes a Digital Twin (DT) approach to evaluating personalized thermal comfort systems.

The SemIoTic Ecosystem: A Semantic Bridge between IoT Devices and Smart Spaces

Smart space administration and application development is challenging in part due to the semantic gap that exists between the high-level requirements of users and the low-level capabilities of IoT devices. The stakeholders in a smart space are …

Abstracting Interactions with IoT Devices Towards a Semantic Vision of Smart Spaces

This paper describes a middleware framework for IoT smart spaces, SemIoTic, that provides application developers and end-users with the semantic domain-relevant view of the smart space, hiding the complexity of having to deal with/understand …

SemIoTic: Bridging the Semantic Gap in IoT Spaces

This demonstration showcases the SemIoTic middleware which provides inhabitants of an IoT space, as well as developers of applications, with a semantic view of the space. Participants will have an opportunity to see how useful IoT applications can be …
