Abstract
A group working sometimes makes unexpected and great idea due to sensitivity interaction. We focus the design of coloration as typical sensitivity information, and describe the synergy effect in a cooperative designing. First of all, we define a psychological model for designer’s synergetic process, and we clear users’ behaviours referring to other’s coloration. Then, we construct an intelligent support system based on this model, which displays efficient reference images for user’s idea on Mixed Reality Display. It provides the virtual coloration with real object in real space, and it helps to give rise to synergy effect of users by themselves.
