This paper focuses on a shadow box, a type of papercraft, and implements an impression-based fabrication support system that automatically generates shadow box expressions suitable for the user’s desired impression. The system consists of a design generation unit creating design candidates and an impression change evaluation model assessing the candidates in terms of their appropriateness to the desired impression. In developing the system, an impression evaluation experiment is first conducted to clarify the relationship between various shadow box expressions and their impression. By training neural networks using the experimental result, a set of impression change evaluation models is implemented. The design generation unit is built based on the approach of an evolutionary computation in which the implemented model set is used as an evaluation function. An impression evaluation experiment for the shadow boxes based on the system output demonstrates the validity of this system.
