Question
Define physiology as used in design technology.
Answer
The study of the systems and biomechanics within the human body — their responses, limitations and capabilities. It tells a designer what a user can DO, where anthropometrics tells them how big the user is.
Question
Name the six physiological limits the guide lists.
Answer
Visual accuracy, colour perception, strength, fatigue, muscle control and hearing thresholds.
Question
Why must colour never be the only way a product signals a state?
Answer
Roughly 1 in 12 men has reduced red–green discrimination, so a colour-only code carries no information for them. Add a second channel — shape, position, a symbol, a pattern or text.
Question
Why design to the sustainable zone rather than the capability ceiling?
Answer
Fatigue lowers what the body can deliver as a task is repeated. A demand that sits just inside the limit for a rested user is outside it later in the shift.
