Investigating the Relationships between Quantitave and Qualitative Properties of 3D Shapes using Fuzzy Logic Models

Defining the aesthetic and emotional value of a product is an important consideration for its design. Furthermore, if several designers are faced with the task to create an object that would evoke a certain emotion (aggressive, soft, heavy, etc.) each would most likely interpret the emotion with a different set of geometric features and shapes.

In this paper the authors propose an automatic approach to formalize the relationships between geometric information of 3D objects and the intended emotion using fuzzy logic. In addition automatically generated fuzzy rules and sets are developed and compared to the user perceptions and manually constructed ones.

The initial findings indicate that the approach is indeed a valid approach to formalize geometric information with emotions.
