II. “Signal Processing: Feature Extraction and Translation” (org. by: Charles W. Anderson, Dennis J. McFarland)

This workshop will focus on issues critical for the signal acquisition, processing, and analysis that are essential for effective BCI systems. These issues include: the technical, physiological, and human factors requirements of real-time operation; the importance of initial and continuing adaptation to each user’s characteristics and capacities, and to spontaneous variations in these capacities; the relative advantages and disadvantages of alternative signal analysis methods (e.g., linear vs. non-linear methods, regression vs. classification models, combinations of temporal and spatial representations, etc.); optimal matching of particular signals with particular processing methods; methods for recognizing and eliminating artifacts (such as EMG or EOG activity); and the requirements for online validation (long-term as well as short-tem) of methods developed through offline analyses.
