This study sought to incorporate handling constraints into the inference process of a kansei engineering system. The proposed system deals with flower arrangements using foams in containers. A purchaser inputs data such as the purpose of the present; relationship with the recipient; and budget. The system receives the data and then retrieves suitable flowers from the database according to the results of a kansei evaluation and social constraints. Then the system displays a list of possible flowers and types of arrangements.
