38. A computer-implemented system for storing and recognizing gestures made by a moving subject within an image, the system comprising: means for building a background model by obtaining at least one frame of an image; means for obtaining a data frame containing a subject performing a part of a subject gesture; means for analyzing the data frame thereby determining particular coordinates of the subject at a particular time while the subject is performing the subject gesture; means for adding the particular coordinates to a frame data set; means for examining the particular coordinates such that the particular coordinates are compared to positional data making up a plurality of recognizable gestures, wherein a recognizable gesture is made up of at least one dimension such that the positional data describes dimensions of the recognized gesture; and means for determining whether a plurality of data frames, where a data frame is represented by the frame data set, when examined in a particular sequence, conveys a subject gesture by the subject that resembles a recognizable gesture, thereby causing an operation based on a predetermined meaning of the recognizable gesture be performed by a computer.

A system as recited in claim 38 further including: means for obtaining a next data frame thereby determining whether the subject gesture has reached a next key point; and means for updating a status report containing data on key points reached in a dimension.
