Introduction

❖Emotions play an important role in product design(Laparra-Hernandez, Belda-Lois, Medina, Campos, & Poveda, 2009).

❖Furthermore, aesthetic and design are decisive buy-arguments in markets in which the technical level of competing products is very similar(Demirbilek & Sener, 2003).

❖Thus, to understand the user’s aesthetic appreciation for industrial products is an important issue in design(Liu, 2003).

LITERATURE

REVIEW

❖Users can evaluate products in their entirety or individual

elements of products which is good for them.

❖Angular forms not only can provide people such cues for danger (Berlyne, 1974) but also increase people’s attention

(Lidwell, Holden, & Butler, 2010).

❖People prefer to appreciation the object with curved form (Bar & Neta, 2006).

？

Does people liking rating of

product increase follow the

curvature of product contour?

Purpose

❖This study’s aim is to explore whether people liking rating of product increase will follow the stimuli that are the same object but diﬀerence between its

(7)

❖Stimuli

The curvatures of stimuli are divided into 0, 1.5, 3.5, 5.5, 7.5, 9.5, 11.5, 13.5, 15.5 and 17.5 mm.

Method

❖Participants

Fifteen students (seven female) were recruited as volunteers.

Their age ranged from 23 to 34 years with a mean age of 26.6 years (SD = 3.22 years).

❖Procedure

The ratings assessed included liking,

curvilineal, technological and comfortable

Conclusions

❖Bar and Neta indicted that the participants generally prefer curved visual objects.

❖Hence, this study investigated the relationship between curvature and liking rating.

❖We find that liking scales followed the curvature of shape in certain case (lower 9.5 mm). The trend has a turning point.

Conclusions

❖First, it may be due to people familiar with iPhone image.

❖Secondly, it may be possible that each kinds of product have the most suitable curvature contour.
