Research paper : Realization of a collaboration system for everyone to develop and manage (K. Eto et al.)−100 Synthesiology - English edition Vol.1 No.2 (2008) is another project of the Author (Eto). In Modulobe, virtual organism created by the user is shared on the net, and other users can create new models by adding changes to the model. ID attached to the parts of the model allows the relationship of re-use of models to become visible. It is similar to qwikWeb since it is an attempt to seek findings by running a system that supports communication among users.Both qwikWeb and Modulobe have common points of “design by subtraction.” The most essential function for the user is considered, while extraneous functions are deleted completely. Therefore, the target users can understand the system more readily. In qwikWeb, comprehensibility was achieved by deleting functions that normally exist such as functions to assign managers or to change editing authority for each page. Although this may make qwikWeb unusable in some situations, we were able to create a system that new users can understand and use immediately.In the future, we shall continue research that supports communication among users and contributes to knowledge sharing on the network.AcknowledgmentPart of this research was supported by Research Topic “Construction of Citizen’s Art Creation Platform by Information Design” in Research Field “Core Technology to Support Production of Digital Media Contents” in Core Research for Evolutionary Science and Technology (CREST) of the Japan Science and Technology Corporation (JST).References[1][2][3][4][5][6][7][8][9][10]Ministry of Internal Affairs and Communications: Results of 2005 “Survey on Use of Communications,” http://www.soumu.go.jp/s-news/2006/060519_1.html (2006) (in Japanese).K.
