SUMMARY: Imagine living in an intuitively interactive space without the need to understand its grammar.
One does not need to interact in a specific way or use voice commands, like Amazon echo, or always wear
something, like a smart band to control the space and the devices therein. Sharing this intelligent space with
others does not also degrade the individual user experience. Interestingly, this vision of seamless smart
spaces is not novel and quite dated; however, we have yet to occupy this kind of space regularly. For this
vision to become an everyday reality, we argue that there is a need for multi-user continuous activity tracking
through passive sensing mechanisms. In this talk, I will discuss how we have developed a pervasive sensing
system for continuous multi-user room-scale tracking of human activities using a single COTS mmWave
radar. We will further highlight how such a sensing system can be utilized for continuous monitoring of
driving activities on the road, to prevent road accidents from driver distraction and promote safe driving. We
will conclude the talk with some potential research challenges where mmWave sensing can help.
