Title: Real-Time Tracking for Multimodal HCI

Abstract:

While multimodal interfaces offer greater flexibility and robustness, they
have been largely pen/voice-based, user activated, and operated in settings
where some constraining devices are required. In this talk, I will discuss
why real-time tracking is important in a multimodal interface and how to
improve human computer interaction by visual information. First, I focus on
techniques of tracking human faces and facial features. I address two
important issues in real-time face tracking: what to track and how to
track. I demonstrate a real-time face tracker that runs on a low-end
workstation or a PC (pentium 233 or above) with a framegrabber and a
camera. I present a top-down approach to tracking facial features. Based
on the face tracker, facial features such as eyes, nostrils, and lip
corners, can be efficiently located within the facial area. I describe
applications of face/facial feature tracking to tele-conference and
multimodal human computer interaction. I conclude my talk by introducing
applications of real-time tracking in an ongoing project - Meeting Room of
Future.

Jie Yang is a Research Computer Scientist in the HCI Institute at Carnegie 
Mellon university, where his main research interest is multimodal human
computer interaction, computer vision, and pattern recognition. Dr. Yang 
is leading a research group in the Interactive Systems Lab to develop 
systems that perceive human activities in the front of a computer and a
meeting room, and assist a human in a mobile environment.
