1. The document discusses interaction on clouds and how communication technologies are enabling new forms of interaction through simultaneous and synergistic use of multiple media. 2. It explores how cloud computing is seen as a possible solution to support media transitions not currently supported by web protocols, and examines emerging computational models like cloud, grid, and cluster computing. 3. Different types of human-cloud interaction are considered, including different user and service types, user behavior trends in cloud usage, and overlapping applications across media.
