Method, apparatus and system for recognizing actions
First Claim
1. A recognition apparatus 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; and
output means for outputting a recognized result.

Abstract
An object of the present invention is to provide a method, an apparatus and a system for automatically recognizing motions and actions of moving objects such as humans, animals and machines.
Measuring instruments are attached to an object under observation. The instruments measure a status change entailing the object'"'"'s motion or action and issue a signal denoting the measurements. A characteristic quantity extraction unit extracts a characteristic quantity from the measurement signal received, the extracted quantity representing the motion or action currently performed by the object under observation. A signal processing unit for motion/action recognition correlates the extracted characteristic quantity with reference data in a database containing previously acquired characteristic quantities of motions and actions. The motion or action represented by the characteristic quantity with the highest degree of correlation is recognized and output.
