Résumé
Human-centered design (HCD, also human-centred design, as used in ISO standards) is an approach to problem-solving commonly used in process, product, service and system design, management, and engineering frameworks that develops solutions to problems by involving the human perspective in all steps of the problem-solving process. Human involvement typically takes place in initially observing the problem within context, brainstorming, conceptualizing, developing of concepts and implementing the solution. Human-centered design is an approach to interactive systems development that aims to make systems usable and useful by focusing on the users, their needs and requirements, and by applying human factors/ergonomics, and usability knowledge and techniques. This approach enhances effectiveness and efficiency, improves human well-being, user satisfaction, accessibility and sustainability; and counteracts possible adverse effects of use on human health, safety and performance. ISO 9241-210:2019(E) Human-centered design builds upon participatory action research by moving beyond participants' involvement and producing solutions to problems rather than solely documenting them. Initial stages usually revolve around immersion, observing, and contextual framing in which- innovators immerse themselves in the problem and community. Subsequent stages may then focus on community brainstorming, modeling and prototyping and implementation in community spaces. Human-centered design has its origins at the intersection of numerous fields including engineering, psychology, anthropology and the arts. As an approach to creative problem-solving in technical and business fields its origins are often traced to the founding of the Stanford University design program in 1958 by Professor John E. Arnold who first proposed the idea that engineering design should be human-centered. This work coincided with the rise of creativity techniques and the subsequent design methods movement in the 1960s.
