Determining states and modifying environments according to states

A device comprising:

• at least one processor;
• and
• memory including instructions executable by the at least one processor to cause the device to perform functions comprising:
• maintaining a state database having individual data corresponding to each of a plurality of desired states for a particular environment, wherein the individual data for each of the plurality of desired states comprises one or more corresponding state attributes describing a desired attribute for the particular environment,
• identifying a need to produce a particular one of the plurality of desired states in the particular environment, wherein the particular desired state involves a user-specific state,
• monitoring the particular environment using a plurality of images from at least one camera on a mobile device positioned in the particular environment, wherein monitoring the particular environment includes performing image analysis on images in the plurality of images to compile an inventory of objects in the particular environment,
• while monitoring the particular environment, detecting a change in the particular environment based on the plurality of images, wherein detecting the change involves identifying a difference in the inventory of objects in the particular environment between a first image and a second image of the plurality of images,
• determining that a user associated with the user-specific state is present in the particular environment, and
• responsive to determining that the user associated with the user-specific state is present in the particular environment and based on the detected change in the particular environment, causing one or more other devices to adjust operation in the particular environment to modify at least one state attribute corresponding to the particular desired state.
