In design, which quality refers to how a product appears and feels?

The quality that refers to how a product appears and feels is known as aesthetics. Aesthetics encompasses the visual elements of design, including color, shape, material, and overall visual appeal. It plays a crucial role in product design, as it affects user perception and emotional response to a product. A well-designed product that is visually appealing and feels good to touch can enhance user satisfaction and make a product more desirable in the marketplace.

Functionality relates to how well a product performs its intended purpose, while durability refers to the product's ability to withstand wear and tear over time. Innovation involves the introduction of new ideas or methods in the design process. While all these factors are important in the overall success of a product, they do not specifically address the visual and tactile qualities that define aesthetics.
