Cognitive ergonomics And design

Ergonomics •

Ergonomics (or human factors) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system • the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance.

Domains:

Cognitive Ergonomics • Cognitive ergonomics is concerned with mental processes, such as perception, memory, reasoning, and motor response. The relevant topics include: • mental workload • decision-making • skilled performance • human-computer interaction, • human reliability • work stress • training as these may relate to human-system Design.

Cognitive processes: • Sensation and perception • Attention and working memory • Thinking and problem solving • Decision making and reasoning Cognitive tools: • Five senses of human • Man made devices

Cognitive Ergonomics in Daily life • Basically it is how work affects the mind, as well as how the mind affects work, so definitely having a great influence in daily life

Human Computer Interaction(HCI) HCI involves the study, planning, and design of the interaction between human

(s) and computers. •

ing knowledge on both the computer and the human

•

Computer side -

techniques in computer graphics operating systems,

programming languages and development environments - relevant •

Human side - communication theory, graphic and industrial design disciplines, linguistics, social sciences, cognitive psychology and human factors such as computer satisfaction - relevant

•

Interaction occurs at the interface

which includes both hardware and

software

Need of cognitive ergonomics • The way people perceive and act has direct implications on the design of the objects and environment that they use

Mind is as comfortable at work as the body • If physical surroundings reflect and their natural cognitive tendencies,  Less errors  performance & productivity -positive boost
