2. INTRODUCTION
Ergonomics
• Work Physiology
• Biomechanics
• Workstation Design
Human Factors
• Experimental Physiology
• Human Performance
• System Design
 Roots:
Due to the introduction of computers into the workplace, human
factors and ergonomics are coming closer
 Development over the last 50 years:
Military Ergonomics
(1950s)
Industrial Ergonomics
(1960s)
Consumer Product
Ergonomics
(1970s)
Human Computer
Ergonomics
(1980s)
Cognitive &
Organization
Ergonomics
(1990s)
Internet
(2000s)

3. INTRODUCTION
Common Goals
• Safety
• Operator Satisfaction
• Productivity
 Ergonomics is rarely a GOAL:
Ergonomics is a design methodology that is used to arrive at safety,
productivity, and satisfaction
This discipline promotes a holistic, human-centred approach, that
considers physical, cognitive, social, organizational, environmental and
other design-relevant factors.
