Analysis of Correlation Between Surface Roughness of Aluminum Alloy and Human Psychological Perception

摘要

As modern products move toward embedded and flat design, the surface materials of products are becoming more and more important in the product experience. However, there has been a strong lack of studies to quantify and link surface materials of products to the human response. Here, we explore the correlation between perception to product surface properties of customers and controllable product surface properties. Analysis reveals five emotional dimensions related to perception of surface physical properties: "uncomfortable - comfortable", "cheap - luxury", "exotic - ordinary", "plain-beauitful" and "artificial - natural". Simultaneously, we deeply explored the relationship between these dimensions and surface roughness of the material. Through the "soft" judgment of psychological attributes and the "hard measurement" of the product surface properties, we have achieved a quantitative assessment of affective surface engineering. These help designers and engineers choose more active material embedded in the product.
