Packet Atmosphere

Packet Atmosphere (パケットアトモスフィア Pakettoatomosufia) is a type of information system built by Government.

Principles
Packet Atmosphere is an information system developed by Government that visualizes the distribution of rumors in an area, like a city. With the cooperation of a major mobile SNS, they can run automatic searches of when and where different keywords were typed in and then the spread of a rumor can be displayed on a map of the area according to time, with the devices that have made corresponding blog entries or SNS posts and their locations listed up on the map with various colors and warnings. By fast-forwarding through time one can see how rumors spread organically through a city, where they are quickly mentioned and forgotten and where they persist or are renewed.

Chronology
Aika used Packet Atmosphere to help Kyousuke Shiroyama and Ryouko Umie investigate the rumors of the Rainy Girl in Toy Dream 35.
