An interactive and responsive presentation of spatially associated information related to a user ' s environment based on the user ' s context is provided. Aspects of a 3D audio cloud system extract information about entities in the user ' s environment , and generate and provide the user with a 3D audio cloud that presents a spatial audio representation of entities in the user ' s environment that gives the user cues as to where the entities are located with respect to the user. An entity can be represented in a descriptive manner that provides the user with various types of information about the entity (e. g. , shape , size , color , others ' opinions , actions , emotions). Further , aspects of the 3D audio cloud system dynamically update the 3D audio cloud based on the user ' s location , position , or orientation , receive selection input from the user associated with the 3D audio cloud , and retrieve and present additional information as requested by the user.
