Research on automobile sketch cooperative design based on image cognition model

Cooperative design between users and designers is one of the most important research items in modern design. Well cooperation between users and designers can get better products in less time. In this research some users´ image cognition experiment researches were taken to obtain users´ image about automobiles. And product image cognition model based on random sets and the product image feature lines - imprecise concept creating technology had been applied to establish a prototype system. So the PIC-CSCDS was developed that designers could do automobile sketch design on this system. And in this way users and designers could carry out design the automobile sketch cooperatively on image level efficiently
