Ubiquitous computing envisions a world in which people can access computing resources anywhere and any time. With advances in both hardware and software, the emergence and availability of a variety of computing devices are making this vision into reality. Powered by these computing devices, ubiquitous computing endeavors to provide new and better solutions to many critical societal problems such as healthcare, education, sustainability, urban planning and community service. In this talk, I emphasize healthcare and sustainability and show how ubiquitous computing technologies can play a pivotal role in each application domain.

First, in the domain of healthcare, I focus on how ubiquitous computing brings new solutions to transform existing healthcare practices to enable personalized healthcare. Specifically, I present new techniques for automatically sensing and recognizing human daily activities using wearable sensing systems. These techniques form the foundation and act as the core technology for a variety of personal healthcare applications, including personal fitness monitoring, long-term preventive care, and intelligent assistance for elderly citizens. Then I present the design of a novel on-body networked sensing system for computerized rehabilitation. The system is capable of detecting key patterns of patients' motor behavior to track precisely the progress patients have made during rehabilitation. Second, in the domain of sustainability, I will focus on how ubiquitous computing increases our understanding of the reciprocal impact between human beings and our living environment. Specifically, I will present the design of a novel ambient environmental sensing system that helps people visualize and assess local indoor air quality. Embedded with artificial intelligence, the system is capable of identifying household activities that are potential sources of indoor air pollution in order to motivate people to make positive behavior changes to create a sustainable living environment. Finally, I discuss some exciting new opportunities that I intend to explore in the near future.
