Reach
“workplace envelope” = 3D space within which you carry out physical work activities when you are at a fixed location.
A scientific discipline concerned with understanding how humans interact with elements of a system.
processes/systems to take proper account of the interaction between the people that use them.
Aims
-
-
-
-
Improve System Performance, Reliability, and Maintenance
ERGONOMICS
-
Physical: deals with subjects related to posture, stress/movement, and occupation of health and safety.
-
Cognitive: concerned with mental processes since they affect interactions between humans and other elements of a system.
-
-
-
subjects include communication, work hours management, crew resource management, teamwork, virtual organizations, telework, and quality management.
-
1.1b
-
human factor data related to physical characteristics used to optimize users’ safety, health, comfort, and performance.

-
Orginal Scales: places importance on the order of value, without telling difference.
-
Ratio Scales: tells exact measurement, the value between units, and range of both descriptive and inferential statistics applied.
EX. weighing scale, driving meter (km).
-
-
-
Observation: either observing behavior in real life, without the person knowing they are being observed OR observed in a lab where they know they are being observed.
Standardized Tests: allows researchers to measure participant’s behavior and mental processes, and then compare them to each other.
Case Studies: in-depth examination on a single individual, could not be generalized to others.

1.1c
Designers study physical characteristics to optimize the user’s safety, health, comfort and performance.
Understanding complex biomechanics and designing products to enable full functionality of body parts can return independence and personal and social well- being to an individual.
Fatigue: When people are put under physical or mental stress/activities for extended periods, fatigue can set in. People react differently when they are fatigued. Errors can creep in which then could prove dangerous. Designers need to understand peoples tolerances and design products and environments that help to reduce fatigue.
Comfort: This various between people. For instance the type of bed that a person will choose is determined by the firmness of the mattress.
