1. An automated method of recognizing a goal of an actor in an environment, the method comprising:
- providing a plan library including a listing of possible goals and plans to accomplish each of the possible goals, each of the plans comprising a plurality of actions for completing the plan;
observing actions relative to the actor;
considering whether hypothesized unobserved actions have occurred; and
identifying one or more plans consistent with the observed actions and the considered occurrence of hypothesized unobserved actions.

Abstract
A system and method for recognizing a goal of an actor in an environment by considering hypothesized unobserved actions. The method includes providing a plan library that includes a list of possible goals and corresponding plans. Actions of the actor are observed, and the occurrence of hypothesized unobserved actions are considered. Finally, one or more plans consistent with the observed actions and the consideration of hypothesized unobserved actions are identified.

15. A computer assisted system for recognizing a goal of an actor in an environment, the system comprising:
-
an information input device for generating information indicative of actions of the actor; a plan library including a listing of possible goals, wherein each goal includes a sub-listing of at least one plan for accomplishing the corresponding goal upon completing the corresponding plan, each plan including a sub-listing of primitive actions for performing that plan; and a controller adapted to; receive information from the information input device, record observed actions, consider whether hypothesized unobserved actions have occurred, identify one or more plans consistent with the observed actions and the considered occurrence of hypothesized unobserved actions. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
