A controller receives an identifier of a detected interaction by a user within another world, separate from a virtual world environment accessible by the user, from a device that detects and reports user interactions within the other world. The controller identifies at least one trigger tag name assigned to the identifier of the detected interaction from among separate detectable user interactions in a trigger tag database. The controller identifies at least one asset class from among asset classes specified with the trigger tag name within a particular trigger asset coupling in a trigger asset coupling database. The controller accesses at least one asset assigned to the at least one asset class in an asset class database. The controller renders the at least one asset within the virtual world environment in a virtual location within the virtual world triggered by the particular trigger asset coupling.
