IOP2603 EXAM PREP.

IOP2603 Study Unit 1 Introduction to Human Factors and Ergonomics Ergonomics = work + laws. The primary purpose of human factors and ergonomics is design. In designing a workplace, the existing situation must first be analysed, new design solutions must be synthesised, and these design solutions must be analysed again. Interdisciplinary system goals; 1. To formulate system goals. 2. To understand functional requirements. 3. To design a new system. 4. To analyse a system. 5. To implement a system. Many HFE experts are designers. Figure 1.2 – page 5 (handboek) Issues to be considered in designing such a system;  Should the user always be in charge or should the computer take over in certain situations?  How should the info on different displays be laid out? What should be displayed?  Can voice recognition understand the pilot even though there is noise in the background?  Are there design constraints? A systematic, interdisciplinary approach is necessary for design and analysis.

Behavioural science studies the intellectual and psychological abilities of the human being.Intellectual abilities and limitations with respect to the functioning of the brain and the nervous system as they determine behaviour. Physical and natural science provide information about the machines and environments people work with and in. Ergonomics – interaction among humans and other elements of a system. It contributes to the design and evaluation tasks, jobs, products, environments, and systems in order ti make them compatible with the needs, abilities and limitations of people.
