Kansei evaluation of matching 2D to 3D images extracted by observation of 3D objects

摘要

In this study, we introduce how people (designers) perceive objects they use in their lives to make them extract their impression into 2D sketches and 3D clay models. Then, it needs to be evaluated by some way to measure the perception related with creation. As resits from the previous experiment of extracting the impression of the form, we gained 26 sets of sketches and clay models from the subjects in different situated observations of different use of objects. With the outputs from the previous experiment, we tried to evaluate the results by a way of non mathmatical but aesthetical way to measure observers' perception on the objects' appearance. Evaluation by matching 2D to 3D those were extracted from the impression of the objects proved the fact why the rational and traditional approach (sketching first modeling later) of design process brings to develop similar forms of products. If the order of approach would be changed flexibly according to the character or theme of products, it will have more possibilities to perceive various ways to be more creative in design approach. Personality is related with the numbers of correct matching. Extraverted stable person matched more than introverted neurotic person. It shows that aesthetic perception which reacts to particular forms may have relation with the personality.
