Method, apparatus and system for recognizing actions
First Claim
1. A method of displaying a position of a subject comprising the steps of:
- recognizing a number of steps, a direction, absolute location of the subject, and action/movement of the subject, based on signals received from a device attached to the subject;
when action/movement recognition indicates movement of the subject, estimating a migration length of the subject based on the recognized number of steps, determined by said recognizing a number of steps, and a predetermined stride for the subject;
calculating a relative position, relative to the absolute location of subject which is a specified location of the subject as an initial value according to the recognized action/movement of the subject, sequentially by using the recognized direction and the estimated migration length;
specifying a position of the subject from the relative position and the absolute location; and
displaying on a display the specific position of the subject.

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 to issue a signal denoting the measurements. A characteristic quantity extraction unit extracts a characteristic quantity from the measurement signal received which represents 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.
