Coarse Feel

Coarse Feel is a tactile surface quality characterized by a rough, granular, or unrefined texture that creates a distinct sensory experience through touch interaction. In the realm of design, this surface attribute plays a crucial role in both functional and aesthetic applications, serving as a deliberate design element that can enhance grip, provide tactile feedback, or create specific emotional responses through materiality. The implementation of coarse textures in design has evolved significantly throughout history, from traditional craftsmanship techniques such as stone carving and woodworking to modern manufacturing processes that can precisely engineer surface roughness. Industrial designers and material scientists often quantify coarse feel through standardized roughness measurements and surface profile analysis, enabling consistent reproduction across various materials and applications. This tactile property has particular significance in ergonomic design, where it can improve user interaction by providing necessary friction and grip, especially in tools, handles, and surfaces requiring secure handling. The psychological impact of coarse textures has been extensively studied, revealing that different degrees of surface roughness can influence user perception, comfort, and product evaluation. In contemporary design practice, coarse feel is frequently employed in sustainable and biophilic design approaches, often mimicking natural textures found in the environment. The A' Design Award has recognized numerous projects that innovatively incorporate coarse textures, particularly in the Materials, Textures, Patterns and Surfaces Design Category, demonstrating the ongoing importance of tactile qualities in modern design solutions.
