Methods and systems for interacting with simulated phenomena are provided. Example embodiments provide a Simulated Phenomena Interaction System “SPIS,” which enables a user to incorporate simulated phenomena into the user's real world environment by interacting with the simulated phenomena. In one embodiment, the SPIS comprises a mobile environment (e.g., a mobile device) and a simulation engine. The mobile environment may be configured as a thin client that remotely communicates with the simulation engine, or it may be configured as a fat client that incorporates one or more of the components of the simulation engine into the mobile device. These components cooperate to define the characteristics and behavior of the simulated phenomena and interact with users via mobile devices. The characteristics and behavior of the simulated phenomena are based in part upon values sensed from the real world, thus achieving a more integrated correspondence between the real world and the simulated world. Interactions, such as detection, measurement, communication, and manipulation, typically are initiated by the mobile device and responded to by the simulation engine based upon characteristics and behavior of the computer-generated and maintained simulated phenomena.
