VUE, or Visual Understanding Environment, led by Tufts University provides and excellent way to explore new information. It would correspond to the network visualization portion of this distributed economy. Unlike Gephi, VUE has the ability to interact with various digital repositories such as those built upon Fedora, interact with the bookmarking and bibliographic service Zotero, merge concept maps and interact with instant messaging to promote collaboration,export RDF, and many other things. In addition, VUE also mildly supports ontologies, which are used in the Semantic Web as frameworks to express a particular domain of knowledge.
Diego Uribe has also demonstrated an extension of VUE through his Digital Creative Problem Solving environment. In his extension, he developed an interactive work space that used infrared tracking technology present in the Wii Remote. He also proposed extensions such as a VUE I-Phone app, the ability for multiple users interacting in real time within the same workspace using Wii Remote technology, the ability to import spreadsheets into the map, importation of VUE into Second Life. He composed a two part Youtube video of his proposals which may be found at the following URLs: http://www.youtube.com/watch?v=LvH2JQsey-c for part 1 and http://www.youtube.com/watch?v=RzVB8KvlqNg for part 2.
