Affective responses of interpolated sketches

Abstract

This study explored the expression differences between designerinterpolated shapes and computer-interpolated shapes under affective perceptual map. Multidimensional scaling (MDS) program was applied to construct product perceptual space as the basis to demonstrate the relationship among interpolation stimuli and affective adjectives. The designer-interpolated kettles have the tendency to design more fresh and modern images. Comparing the average distance between designer-interpolated kettles and midpoint of the source kettle, it is clear that the operations of interpolation image on the “simplecomplex” axis are easier to create than the “contemporary-traditional” and “emotional-rational” axes. This study also proves the relationship between the computer-interpolated shapes and their affective responses to be nonlinear and non-uniform. The results showed under a condition of free design expression for the designer, the design purpose not only yields a finished product appearance but also represents the designer’s will.
