We are witnessing the explosion of connected devices, or the so-called Internet of Things, in our everyday lives. This new trend has created new opportunities to monitor human activities and to configure environments for comfort, security, or energy savings. In the US, buildings account for roughly 40% of total energy usage, with major contributions from the cooling demands. While most people have no intention of wasting energy, they are often unaware of the energy footprint of their daily routines. Activity recognition is a key capability for a smart environment to offer timely services and intelligent interactions with people.

In this talk, I will introduce connected context computing and its significance in enabling our vision of smart IoT. In particular, I will share our experience on monitoring the Computer Science building on NTU campus to improve its air conditioning and space utilization. First, an agent-based HVAC service is designed to analyze cooling demands and wastes. Second, experiments on SweetFeedback are conducted to encourage energy-saving behaviors. Third, crowd sourcing cyber-physical agents are deployed to acquire status labels for activity recognition from people situated in the environment. Â Our experiments showed that context computing, predictive analytics, and proactive control are the fundamental building blocks for a smart IoT framework that can SCALE (Sense, Communicate, Analyze, Learn, Expect and Effect).
