Modeling Human Actions to Enabling Behavior Change: From Surveillance to Healthcare

Friday, April 5, 2013
11:00 AM  to 12:00 PM

I will present my work in the area of human activity modeling via two research strands. The first research strand involves human activity inference in the presence of resource constraints. In this agenda, we exemplify resource constrained processing by the use of symbolic approximation strategies for reduced bit-budgets between sensor and base station, as well as the use of compressive cameras for low-bit rate acquisition. In both cases, we will show how a careful analysis of underlying feature spaces informs effective inference strategies, that do not require reconstruction of the original video data.

As the second research strand, I will describe inter-disciplinary health and well-being projects that center around construction of experiential systems that enable behavior change. We are involved in creating a home-based system for stroke rehabilitation with real-time feedback, and long-term engaging narratives for home-based delivery of such 'reactive' healthcare. We have also started work on preventive systems for managing and prevention of mobility disorders using portable technology, media feedback, and experiential construction. In these applications, I will discuss the collaborations with artists, engineers, media designers, and healthcare professionals that are crucial for such home-based deployments. I will also touch upon the computer vision and machine learning challenges that I am addressing in these applications. We hope to reach out to relevant groups at Rice and build complementary research partnerships.

Biography of Pavan Turaga:
Pavan Turaga joined Arizona State University (ASU) in Fall 2011 as an Asst. Prof. jointly between the departments of Arts, Media, and Engineering and Electrical Engineering (ECEE). He obtained his PhD in 2009 from the ECE Department at the University of Maryland, College Park under the guidance of Prof. Rama Chellappa. He then spent two years as a Research Associate at the Center for Automation Research, UMD. His broad research interests are in the areas of computer vision, machine learning, and and multi-modal real-time systems for health and well-being. He was named 'Emerging Leader in Multimedia' by IBM T.J. Watson Lab in 2008, and received the Distinguished Dissertation Award from UMD in 2009.
