   The Role of Biofeedback in Everyday Applications for People with Disabilities

Biofeedback refers to the physiological signals that could assist the confrontation of diagnosed disorders. However, the use of this information could be transferred to other areas, such as applications for disabled people, providing new ways of dealing with their everyday special needs. From this perspective, the proposed lecture presents the innovative use of biofeedback towards: (a) automated recognition of sign language gestures, through surface electromyogram, as a means to facilitate the communication of deaf people with the others, and (b) the educational evolution of autistic kids, through their emotional screening via galvanic skin response and heart rate variability. The characteristics of these two case studies are presented and specific analysis and implementation issues are discussed. Initial results show the efficiency of these biofeedback data to discriminate between different sign language gestures (> 90%) and to provide a means that accounts for the emotional state of the autistic kid during the educational process. In this way, a normalization of the communication and education environment, respectively, is feasible, providing the opportunity to create applications that could facilitate and be integrated in the everyday life of people with disabilities.
Leontios J. Hadjileontiadis was born in Kastoria, Greece in 1966. He received the Diploma degree in electrical engineering in 1989 and the Ph.D. degree in electrical and computer engineering in 1997, both from the Aristotle University of Thessaloniki, Thessaloniki, Greece.
Since December 1999 he joined the Department of Electrical and Computer Engineering, Aristotle University of Thessaloniki, Thessaloniki, Greece as a faculty member, where he is currently an Assistant Professor, working on lung sounds, heart sounds, bowel sounds, ECG data compression, seismic data analysis, and crack detection in the Signal Processing and Biomedical Technology Unit of the Telecommunications Laboratory. His research interests are in higher-order statistics, alpha-stable distributions, higher-order zero crossings, wavelets, polyspectra, fractals, neuro-fuzzy modeling for medical, mobile and digital signal processing applications.
Dr. Hadjileontiadis is a member of the Technical Chamber of Greece, of the IEEE, of the Higher-Order Statistics Society, of the International Lung Sound Association, and of the American College of Chest Physicians. He was the recipient of the second Award at the Best Paper Competition of the ninth Panhellenic Medical Conference on Thorax Diseases'97, Thessaloniki. He was also an open finalist at the Student paper Competition (Whitaker Foundation) of the IEEE EMBS'97, Chicago, IL, a finalist at the Student Paper Competition (in memory of Dick Poortvliet) of the MEDICON'98, Lemesos, Cyprus, and the recipient of the Young Scientist Award of the twenty-fourth International Lung Sounds Conference'99, Marburg, Germany. In 2004, he organized and served as a mentor to a five-student team that has received the third Award worldwide at the Imagine Cup 2004 Competition (Microsoft), Sao Paulo, Brazil, with the project “SmartEyes: An enhanced navigation system for blind or visually impaired people”.
Dr. Hadjileontiadis also holds a Ph.D. degree in music composition (University of York, UK, 2004) and he is currently a Professor in composition at the State Conservatory of Thessaloniki, Greece.
