Both of the readings for this week have similarities and differences with each other, but one common thread among these readings that I tried to follow and extract was the role of human subjectivity in design. The first reading introduces psychological concepts in the form of affect and analyzes how they interact with design. The second reading shows the importance of it more subtly, by showing how a hazardous error was found by a kid playing around with the keyboard, and the same error was committed by an astronaut that was believed to be exceptionally professional. Unfortunately, nobody is perfect, and every human holds a different set of characteristics and, therefore, has a different perspective on the world and the tools they use. Hence, the one idea I would connect these readings with is the idea of personalization in design. Just like the three teapots in Norman’s text, different design has different form and functionality and can suit different people to accomplish a task. Even the same person in different moods or environments could desire a different design. If this idea is paired with the “beauty is subjective” discussion, we can see how personalization of design is important from Norman’s ideas about attractive things working better. As much as we like to think of ourselves as rational and intelligent creatures, humans are emotional at core and this should be reflected in good design, incorporating emotional choices along with functional choices.
