public class ShakeWellBeforeUseParameters
extends java.lang.Object

This class defines constants for the motion authentication protocols. The optimal values were found by a full parameter search over an extensive real-world data set. See Rene Mayrhofer, Hans Gellersen: "Generating Secret Shared Keys from Common Movement Patterns", Pervasive 2007 for details.
