Human-centered design is based on the physical and psychological needs of the human user, enabling the user to function at the highest level possible. It includes products and aspects of the physical environment that meet the needs and abilities of the user, not those that demand adaptation to the design by the user. Human- centered design is not a design style, but is a process for designing and developing buildings, products, and communities that is grounded in information about the people who will be using them—utilizing research findings and data on cognitive abilities, physical abilities and limitations, social needs, and task requirements in order to provide living-environment solutions that enable all users to function at their highest capacity—regardless of age or ability.
