Method, apparatus and system for recognizing actions

A recognition system for recognizing motions and/or actions of an object under observation, said recognition apparatus comprising:

• measurement means attached to said object under observation in order to measure a status change entailing the motions and/or actions of said object under observation;
• characteristic quantity extraction means for extracting characteristic quantities from the measurements taken by said measurement means;
• recognition means for recognizing the motions and/or actions of said object under observation in accordance with the characteristic quantities extracted from said measurements,
• output means for outputting a recognized result;
• further comprising characteristic quantity composition means for selecting a plurality of quantities from among the characteristic quantities stored in said storage means so as to compose the selected characteristic quantities into a new characteristic quantity;
• wherein said recognition means recognizes, given the newly composed characteristic quantity and the characteristic quantities corresponding to said measurements, the motions and/or actions of said object under observation as those composed of a plurality of motions and/or actions corresponding to the selected characteristic quantities.

A recognition system for recognizing motions and/or actions of an object under observation, said recognition apparatus comprising:

• measurement means attached to said object under observation in order to measure a status change entailing the motions and/or actions of said object under observation;
• characteristic quantity extraction means for extracting characteristic quantities from the measurements taken by said measurement means;
• recognition means for recognizing the motions and/or actions of said object under observation in accordance with the characteristic quantities extracted from said measurements;
