Perception and Action. Visual information is sometimes referred to as a product's design language or product semantics . The designer can articulate the design of the product to be more or less intuitive. Using software to manipulate color, form, scale, organization, and texture can each contribute to the explicitness of use and operation. Systematically evaluating design and ergonomic requirements using anthropometric data will have a direct and tangible effect on a product's success in the form of fewer errors, better efficiency, and improved functionality.
Usability studies provide the basis for product planning, design, and marketing.
