Question
What does psychology cover in this course?
Answer
The study of the human mind, including all the senses that send information to the brain — sight, sound, touch, smell and taste — and how they influence the design and development of products.
Question
Give a design use for smell and for taste.
Answer
Smell: an odorant added to naturally odourless natural gas so leaks are detected. Taste: a bittering agent in detergent capsules so a child spits one out.
Question
What is sensory redundancy and why does it matter?
Answer
Carrying critical information through more than one sense — an alarm that both sounds and flashes. A single channel fails completely for part of the user group, while two degrade gracefully.
Question
Why do touchscreens add a click and a vibration?
Answer
A flat screen gives no tactile detent, so the user has no confirmation that a press registered. Sound and haptics replace the feedback a physical button would have given by touch.
