1. An intermediary engine, comprising: a hardware processor; and a non-transitory storage device for storing instructions to be executed by the hardware processor; wherein the instructions, when executed by the hardware processor, cause the hardware processor to perform operations comprising: receiving a measure of a mood of an individual, wherein the measure of the mood is synthesized from changes that are identified in collected information associated with a behavior of the individual, wherein the collected information includes one of media content consumed by the individual, images of the individual captured by a group of cameras at a plurality of locations, audio recordings of the individual captured by a plurality of end user devices or a combination thereof, wherein the mood indicates an availability of the individual and a receptiveness of the individual to accept a request to interact with an entity, wherein the measure of the mood includes a group of dimensions comprising a first dimension identifying a plurality of metaphor expressions to express the mood of the individual to interact with the entity, a second dimension identifying a plurality of techniques to disclose activities of the individual to the entity, and a third dimension identifying a group of strategies to provide the entity a degree of access to the individual; selecting an interactive avatar having characteristics determined from the measure of the mood of the individual; presenting the interactive avatar; and managing interactions between the individual, the interactive avatar and the entity according to a selected strategy that is selected from among the group of strategies according to the measure of the mood of the individual, wherein the group of strategies is pre-determined and stored, wherein the managing of the interactions includes generating queries for presentation via the interactive avatar and performing actions by the interactive avatar responsive to user input responding to the queries, wherein the queries and the actions are selected from pre-determined queries and pre-determined actions identified by the selected strategy, wherein weighting factors are applied to the collected information for synthesizing of the changes, wherein the images of the individual captured by the group of cameras at the plurality of locations are utilized for determining activities of the individual and environments of the individual, and wherein the group of dimensions of the measure of the mood includes a fourth dimension identifying a plurality of intermediaries to negotiate with the entity the degree of access to the individual, and a fifth dimension identifying a plurality of parties and context of activities of the individual to create a plurality of multidimensional scenarios.
