BACKGROUND

There are many environments in which humans interact with various objects. For example, in retail shopping areas, human shoppers may take objects for purchase from the shelves to the cash registers while human workers may restock shelves, rearrange products, and help shoppers complete purchases.

SUMMARY

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.

A camera system is configured to automatically monitor an area. Depth image(s) of the area are acquired based on active IR light emitted by the camera system and reflected from the area to a sensor array of the camera system. The depth image(s) are computer analyzed to identify a human subject. For each spectral illuminator of the camera system, spectral light image(s) of the area are acquired based on active spectral light in the spectral light sub-band of the spectral illuminator reflected from the area to the sensor array. The spectral light image(s) for the spectral illuminators are computer analyzed to identify an interaction between the human subject and an object in the area. The spectral information also may be used to support identification of the human subject and the object. In response to identifying the interaction between the human subject and the object in the area, an action to be performed for the object is computer issued.
