1. A computer-implemented method of detecting a waving motion in a sequence of ordered points, the method comprising:
- receiving a sequence of ordered points;
selecting a subset of the sequence of ordered points;
determining if the subset defines a waving motion; and
storing an indication of whether or not the subset defines a waving motion.

Abstract
A system and method for detecting a waving motion from a sequence of ordered points is disclosed. In one embodiment, the method comprising receiving a sequence of ordered points, selecting a subset of the sequence of ordered points, determining if the subset defines a circular shape, and storing an indication of whether or not the subset defines a waving motion. Various metrics for determining if the subset defines a waving motion, which allow for a trade-off between accuracy and complexity, are disclosed.
