Week 12 Session: The Perfect Button

Returning to the semester's central question with the strongest button built this course, one buttonless comparison, and a final defence.

10 May 2027

The course opened with one question: what makes a button feel worth pressing? Twelve weeks have answered pieces of it without stating the whole thing at once. This week asks for the whole thing.

What the semester actually gave you#

• a physical ancestry, from Weeks 1 and 2: what a button is before and after it becomes a rectangle on glass
• pressability, from Week 3: the difference between looking pressable and being pressable
• a promise, from Week 4: what state change the button is actually claiming
• a length, from Week 5: how long silence can last before the promise reads as broken
• a reward, from Week 6: what makes a button worth pressing again
• a failure, from Week 7: what a button teaches you once it stops working
• a habit, from Week 8: what a button becomes once it stops being looked at
• a hand, from Week 9: whether the same mechanism holds for someone different from whoever built it
• a friction, from Week 10: what should stand between a press and its consequence
• an honesty, from Week 11: what a button owes the person pressing it

None of these are independent checklist items. A button that satisfies all ten and still isn’t worth pressing is a button that got the individual pieces right and the whole thing wrong.

The strongest button you built#

Choose the single strongest button you produced this semester — from any week’s log, prototype, or redesign. Say which week it came from and why you’re choosing it over the others.

One buttonless comparison#

Build one buttonless alternative that accomplishes the same action — a gesture, a voice command, an automatic trigger, whatever removes the press entirely. Build this only to find out what the button was contributing. This is a comparison, not a replacement: the semester does not end with the conclusion that buttons should disappear.

Note specifically what the buttonless version lost — acknowledgement, a deliberate moment before an irreversible action, something else you can name.

The final button, defended#

Produce a final version of your chosen button, revised in light of the comparison. Then write its defence: name at least four specific ideas from Weeks 1–11 it satisfies, and state, in your own words, why this button earns the press it asks for.

This defence is the direct rehearsal for The Perfect Button, the semester’s final assessment. The assessment brief itself is not part of this session.

Twelve weeks ago the course asked what makes a button feel worth pressing. Your defence is the answer, argued for one specific button instead of all of them.
