Portuguese Conference on Pattern Recognition

In a sentence, physiological computing (PC) deals with the study and development of interactive systems that sense and react to the human body. The most basic sort of PC simply records a signal, such as a heartbeat, and displays it on a screen. More complex systems work on a basis of a bio-cybernetic loop, the main purpose of this loop being to translate patterns of physiological activity into meaningful interaction. From emotional status to identity assessment, this talk addresses the exploration of electrophysiological data in the context of intelligent human-computer interaction. Electrocardiographic signals and electro-dermal responses, acquired in a pervasive manner at the hands level, are shown to be two complementary modalities in the emotion / identity dual assessment goal. The role of pattern recognition in the development of such systems is discussed. Finally, BITalino, a versatile and low cost biosignal acquisition system is presented as a promising tool for pervasive biosignal monitoring and physiological computation. Speaker Biography: Ana Fred received the M.S. and Ph.D. degrees in Electrical and Computer Engineering, in 1989 and1994, respectively, both from Instituto Superior Técnico (IST), Technical University of Lisbon, Portugal. She is a Faculty Member of IST since 1986, where she is currently a professor with the Department of Electrical and Computer Engineering. She is a researcher at the Pattern and Image Analysis Group of the Instituto de Telecomunicações. Her main research areas are on pattern recognition, both structural and statistical approaches, with application to data mining, learning systems, behavioral biometrics, and biomedical applications. She has done pioneering work on clustering, namely on cluster ensemble approaches. Recent work on biosensors hardware (including BITalino – www.bitalino.com) and ECG-based biometrics (Vitalidi project) have been object of several national and international awards, as well as wide dissemination on international media, constituting a success story of knowledge transfer from research to market. She has published over 160 papers in international refereed conferences, peer reviewed journals, and book chapters. She received the "Best paper award in Pattern Recognition and Basic Technologies", awarded by the IAPR, for the paper “Learning pairwise similarity for data clustering”. She is the editor of over 40 books with the proceedings of international workshops that she organized or co-chaired, including S+SSPR 2004 (Lisbon), S+SSPR 2006 (Hong Kong), ICAART, KDIR and BIOSTEC and editor of 12 Springer books of selected papers.
