Item-typ:Veröffentlichung, Design with Sustainable Materials: Predicting Consumer Perception of Biobased Composites(Jomard Publishing, 2025-12); ; ; ; The product designer's role in promoting sustainable materials is crucial, as designers make material selections for products on behalf of consumers. In this study, we examine this assertion of designers' ability to empathise with consumers and investigate if their perception of biobased composites aligns with that of consumers. A perception framework for biobased composites, proposed in prior research, is applied in this study to predict consumer perception of materials. The roles of various visual/tactile factors that affect crucial perceptual attributes (beauty, naturality, strength and value) are also examined. An evident perceptual incongruity between designers and consumers was observed, diminishing the claim of designers' ability to empathise with consumers in the remit of biobased composites. It is also noted that the proposed perception framework generates reliable predictions of consumer perception for biobased composites and can thus assist designers in material selection.Wissenschaftlicher ArtikelBand:9Heft:312 - Some of the metrics are blocked by yourconsent settings
Item-typ:Veröffentlichung, Designing with biobased composites: understanding digital material perception through semiotic attributes(Cambridge University Press (CUP), 2023); ; ; ; Biobased composites, which are considered a sustainable alternative to plastics, are yet to create a significant influence on product design and manufacturing. A key reason for this is perceptual handicaps associated with biobased composites and this study was aimed at understanding the mechanisms behind biocomposite perception, in the context of digital visuals. This study of digital biocomposite visuals demonstrated that material perception is influenced by the visual characteristics of the material. Data analysis of the perceptual attributes of the materials pointed towards clear ‘clustering’ of the materials against these attributes. Analysis shows that visual features like fibres and surface appearance may impact aesthetic and functional evaluation and there is no effect on age, gender or polymer type. We also propose a reference framework to categorise biobased composites based on visual order.Wissenschaftlicher ArtikelHeft:969 - Some of the metrics are blocked by yourconsent settings
Item-typ:Veröffentlichung, Visual-Tactile Perception of Biobased CompositesBiobased composites offer unique properties in the context of sustainable material production as well as end-of-life disposal, which places them as viable alternatives to fossil-fuel-based materials. However, the large-scale application of these materials in product design is hindered by their perceptual handicaps and understanding the mechanism of biobased composite perception, and its constituents could pave the way to creating commercially successful biobased composites. This study examines the role of bimodal (visual and tactile) sensory evaluation in the formation of biobased composite perception through the Semantic Differential method. It is observed that the biobased composites could be grouped into different clusters based on the dominance and interplay of various senses in perception forming. Attributes such as Natural, Beautiful, and Valuable are seen to correlate with each other positively and are influenced by both visual and tactile characteristics of the biobased composites. Attributes such as Complex, Interesting, and Unusual are also positively correlated but dominated by visual stimuli. The perceptual relationships and components of beauty, naturality, and value and their constituent attributes are identified, along with the visual and tactile characteristics that influence these assessments. Material design leveraging these biobased composite characteristics could lead to the creation of sustainable materials that would be more attractive to designers and consumers.Wissenschaftlicher ArtikelBand:16Heft:5134 - Some of the metrics are blocked by yourconsent settings
Item-typ:Veröffentlichung, Designing Sustainable Materials: The Role of Material Perception in Consumer Acceptance(Jomard Publishing, 2025-04); ; ; ; Material perception is vital in designing new materials and products that consumers widely accept, especially in the case of sustainable materials like biobased composites, which are unfamiliar to the average consumer. Understanding the effect of visual and tactile characteristics of the biobased composites on the formation of material perception could help material engineers and designers create sustainable and high-value materials. In this study of biobased composites, the semantic differential method is used to assess material attributes (in digital and physical settings), along with the qualitative assessment of material characteristics. These attribute ratings and qualitative descriptors help evaluate sensory qualities and generalise their influences on material perception. It is observed that respondents refer to past material experiences to define materials, especially the ones with uncertain attributes. While visual/tactile inconsistencies are a hallmark of natural products, such irregularities in materials with evidence of human interaction (e.g., weaving, geometric patterns) lead to poor perception of beauty and value. Fibreness is a strong signifier of naturality and warm and earthy tones reinforce this perception. Visual and tactile attributes influence perceptions of beauty and values, pointing to their bimodal nature; this also emphasises the role of sensory characteristics in creating desirable biobased composites.Wissenschaftlicher ArtikelBand:9Heft:110
