The beauty of kasuri is received as a gift. As long as the laws of nature are upheld, the beauty of kasuri remains intact. This demonstrates the curious principle that the artisan is deprived of technical freedom but works in the freedom of nature.
In this sense, kasuri can be said to be created in a state of freedomless freedom.
In the automobile's technological middle age, it is hard, if not impossible, to tune or repair one's own vehicle. Technical standardization of cars has occurred, and with it the elimination of the user's access to the machine itself. At the same time, the infrastructures that once served those who did not use automobiles atrophied and vanished. Some may say they were deliberately starved out. Railways gave way to more and more roadways. And thus a technology that had been perceived to liberate its users began to enslave them.
What do we have that they should want?
We have a wall to work upon
We have work and they have none
And our work is never done
And the war is never won
The enemy is poverty
And the wall keeps out the enemy
And we build the wall to keep us free
That’s why we build the wall
We build the wall to keep us free
Perceptual: "They couldn't figure out what to do next", "they couldn't find the feature", "they didn't know they could click that button..." etc.
Domain-specific: "We need a way to jump back here because in their workflow this happens..."
In general, usability testing only catches type 1 perceptual problems. Because in those tests you take people out of the real world and assign them tasks. Usability testing doesn't catch domain-specific problems because they only come up in real life use.
