US Patent 9965793 Item selection based on dimensional criteria

Systems and methods are provided for determining dimensional criteria of a physical space and identifying a set of items that satisfy the dimensional criteria. For example, the dimensional criteria may be determined based on an image depicting the physical space or search terms provided by a user. Composite keys may be generated based on the dimensional criteria and one or more search terms provided by the user, and the generated composite keys may be used to search one or more databases storing sorted item keys and corresponding item identifiers.
