The customer Byeon Chan-woo opened the door for fresh air.
1) The customer asks for the meeting room door to be opened.
2) Once the door is open, it’s noisy. They close the door again.
3) They close the door and turn on the ventilator.
-> Usually, among who / why / what, we focus only on the “what.”
-> Is closing the door really the important requirement, or is “freshness” the main requirement? That’s the point you need to recognize clearly.
Selective attention
- (YouTube → the gorilla and the basketball), (receptor cells; the place you stare at is not necessarily where you are “attending”).
- Preattention stage, focused attention, feature integration theory.
The problem of driving change
1) Don’t use the word “change.”
- Try change in small, small steps so that even if it fails, no one notices.
- Don’t mention the terminology or the tool names that come with “change.”
2) Raise the transparency of what each of you is doing, so the goal isn’t lost.
- “Let’s check in the middle” → do it more often (or even 15 minutes daily), expressed visually (as charts and diagrams).
3) Whatever it is, the point isn’t to just “do the work.”
cognitive factors
saccade: from an evolutionary standpoint, if you can’t do this, you’re effectively a fool.
The suffering of the left-handed
- Universal design (elevator: improving subway stairs that removed a barrier): making it so that disabilities aren’t separated out but are concealed.
- Flexible design
- Design for whole life
- Barrier free
- Examples: Playtex’s curved baby bottle (the surface itself acts as a handle; uses airflow to reduce colic).
The lighter (used to take two hands; after the war it was designed for one-handed use).
The bidet (from medical-device design for patients to design for everyone).
The gestures and shouts of baseball umpires (designed for deaf players).
In games, your level keeps rising as time goes by, but a person, as they age, at some point begins to grow weaker and weaker.
: And yet most designs are built to fit the peak-level player.
As devices with varying screen sizes proliferate, consumers’ usage patterns are changing.
Of course, depending on the gap between rich and poor, some optimize their use of each device for each screen, while others try to do everything with a single device.
Typically, the consumption pattern around smart devices is said to be about 1/10 of annual income.
Beyond just UX —
a well-designed team has good feedback loops, finds mistakes (i.e. constructive failure) quickly, and corrects them quickly.
