"1. Motivation—errors or ideas Design ought to start from understanding the problems that people are having, and also from ideals. A lot of people are motivated by problems that they see, breakdowns of one sort or another, errors that they observe. Another place that design starts is with ideas. Thes"

"This hierarchy shows the increasing complexity of the relevant constraints, if you consider each type of design problem from the point of view of the user.The hierarchy is based on the type of human factors that is relevant to the design context in each level of complexity, starting with the simples"
"A Hierarchy of Complexity When I graduated from college as an industrial designer in 1965, I expected to spend my life designing mass-produced objects to be manufactured in metals and plastics.Thinking about what people want from an object was a predominant consideration for the design, but there wa"
"Anthropometrics—the sizes of people For the design of physical objects The constraints are complex enough to demand the core skills of design, but the problems are well understood and have been evolving slowly since industrial design emerged as a new discipline in response to the Industrial Revoluti"
"Physiology—the way the body works For the design of physical man-machine systems The next level of complexity comes when you need to consider actions as well as objects. If the design context includes what the person is doing as well as the things that they are using, the constraints need to include"
