ABSTRACT

Abstract The product form is more than an enclosure of a product. Some studies suggest that product form, as a physical quality, informs the user of the meanings of functionality and utilitarian features (a bottom-up approach); however, some suggest product form is a communication medium dependent on the context. Others suggest form is a construction of meanings by evoking pleasure and emotion (a top-down approach). The purpose of this study is to investigate the relationships between perceived meanings (e.g., safety, elegance) and product form (roundness in multiple dimensions) in an experimental setting. Participants in the experiment interacted with nine hard drive and nine soap dispenser prototypes and provided Likert scale scores about meaning (similar to semantic differential method) for each prototype. The edge and/or corner roundness of these prototypes was manipulated from crisp 90° edges to round edges along two and three dimensions. Results suggest that physical quality of the form and the perceived meaning follow a pattern akin to Fechner's law of perception – mostly non-linear relationships. A small change in product form resulted in a large impact on meaning, and moderate manipulations in product form was more likely to confuse participants. Thus, this investigation underscores that product form should be managed carefully by product designers and companies. Relevance to industry This study provides an empirical data which presents the relationship between product from and perceived meanings. The proposed approach reveals that this relationship is mostly non-linear; therefore, it is delicate and requires extra attention. Knowledge gained from the study is beneficial for product designers when communicating clearly with users via product forms, and as a result achieve commercial success. The study also provides evidence to support interactionist theoretical framework when describing meaning attribution process to product forms.
