38. The gesture identification system of claim 34 wherein the at least one sensor includes N sensors, where N>1, and wherein each window class in the library of window classes exclusively characterizes a respective region in an N-dimensional hyperspace and each dimension of the N-dimensional hyperspace represents a property of the signal from a respective one of the N sensors.
