Is the science of refining the design of products to optimize them for human use. Human characteristics, such as height, weight, and proportions are considered, as well as information about human hearing, sight, temperature preferences, and so on. Ergonomics is sometimes known as human factors engineering.

Computers and related products, such as computer desks and chairs, are frequently the focus of ergonomic design. A great number of people use these products for extended periods of time -- such as the typical work day. If these products are poorly designed or improperly adjusted for human use, the person using them may suffer unnecessary fatigue, stress, and even injury.


Is the making of a plan and convention the main for the construction, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns). Design can have different connotations in different fields. In some cases, the direct construction of an object (as in pottery, engineering, management, coding, and graphic design) is also considered to be design.

Designing often necessitates considering the aesthetic, functional, economic, and sociopolitical dimensions of both the design object and design process. It may involve considerable research, thought, modeling, interactive adjustment, and re-design. Meanwhile, diverse kinds of objects may be designed, including clothing, graphical user interfaces, skyscrapers, corporate identities, business processes, and even methods of designing.
