Action recognition and interpretation using a precision positioning system
First Claim
1. In an environment comprising a precision positioning system adapted to provide position information corresponding to an entity within the environment and an entity recognition system adapted to provide information identifying the entity, a method of recognizing an action undertaken by the entity within the environment, the method comprising:
- determining, by the entity recognition system, an identity of the entity;
determining, by the precision positioning system, position data corresponding to at least a portion of the entity within the environment, the environment comprising a space substantially larger than the entity;
comparing the position data to at least one known action corresponding to a predetermined task within the environment;
recognizing the action when the position data compares favorably with the at least one known action; and
determining whether the entity is authorized to perform the action based on the identity of the entity.

Abstract
To facilitate the recognition and interpretation of actions undertaken within an environment, the environment is associated with a precision positioning system (PPS) and a controller in communication with the PPS. Within the environment, an entity moves about in furtherance of one or more tasks to be completed within the environment. The PPS determines position data corresponding to at least a portion of the entity, which position data is subsequently compared with at least one known action corresponding to a predetermined task within the environment. Using a state-based task model, recognized actions may be interpreted and used to initiate at least one system action based on the current state of the task model and correspondence of the position data to the at least one known action. In an embodiment, an entity recognition system provides an identity of the entity to determine whether the entity is authorized to perform an action.

-
determining, by the entity recognition system, an identity of the entity; determining, by the precision positioning system, position data corresponding to at least a portion of the entity within the environment, the environment comprising a space substantially larger than the entity; comparing the position data to at least one known action corresponding to a predetermined task within the environment; recognizing the action when the position data compares favorably with the at least one known action; and determining whether the entity is authorized to perform the action based on the identity of the entity. - View Dependent Claims (2, 3, 4, 5, 6)

7. A system for recognizing an action performed by an entity within an environment, comprising:
-
an entity recognition system, associated with the environment and adapted to determine an identity of the entity; a precision positioning system comprising a plurality of detectors associated with the environment; at least one tag, physically associated with the entity and in communication with at least some of the plurality of detectors, wherein the precision positioning system via the at least some of the plurality of detectors provides position data corresponding to the at least one tag, the position data describing the action by the entity; and a controller, in communication with the plurality of detectors and the entity recognition system, operative to recognize the action based on correspondence of the position data to one or more reference actions corresponding to a predetermined task within the environment and to determine whether the entity is authorized to perform the action based on the identity of the entity. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. An apparatus comprising:
-
at least one processor; and at least one storage device, coupled to the at least one processor, comprising processor-executable instructions that, when executed by the at least one processor, cause the at least one processor to; receive, from an entity recognition system associated with an environment comprising a space substantially larger than an entity within the environment, an identity of the entity; receive, from a precision positioning system adapted to provide position information corresponding to the entity, position data corresponding to at least a portion of the entity within the environment; compare the position data to one or more reference actions corresponding to a predetermined task within the environment; recognize the action when the position data compares favorably with a reference action of the one or more reference actions; and determine whether the entity is authorized to perform the action based on the identity of the entity. - View Dependent Claims (18)
