Claim Text:
1. A method comprising: tracking a plurality of subjects using video image processing to generate video tracks of the plurality of subjects, the plurality of subjects including subjects of a first type and subjects of a second type; tracking the subjects of the first type using wireless signals received from radio frequency tags coupled to the subjects of the first type to generate wireless tracks of the subjects of the first type; comparing the wireless tracks of the subjects of the first type to the video tracks of the plurality of subjects to identify video tracks associated with the subjects of the first type and to identify video tracks associated with the subjects of the second type; based on the comparison, labeling a first subset of the video tracks identified as being associated with the subjects of the first type and labeling a second subset of the video track identified as being associated with the subjects of the second type; analyzing the first subset of the video tracks and the second subset of the video tracks to identify interactions between a first subject of the first type and a first subject of the second type in a first area based on a first video track of the first subset of video tracks being within a first predetermined distance to a first video track of the second subset of video tracks for a first predetermined period of time, and to identify interactions between a second subject of the first type and a second subject of the second type in a second area based on a second video track of the first subset of video tracks being within a second predetermined distance to a second video track of the second subset of video tracks for a second predetermined period of time, wherein the first predetermined distance is different than the second predetermined distance or the first predetermined period of time is different than the second predetermined period of time; and providing, for display, a report of the identified interactions based on a result from the analyzing the first and second subsets of the video tracks.
