It is a dead giveaway for a self-proclaimed HCD (Human-Centered
Design) practitioner to look for an HCD manual. No wonder you deny the
HCD basic belief of adapting to user.

I'd already walked you through the reasoning. But the bottleneck here
seems to be your polarization.

For instance, you polarized "activity-centered design" into "activity
drives design". You then argued against the polarized version by
asserting that design should drive activity:

Similarly, you polarized "activity" into "current activity" and then
argued that there is no current activity to drive the design of a
violin:

AJ> There was no current activity to drive the design. The violin was
AJ> designed for an activity that no one were doing.

Do you really believe that invention cannot be triggered by studying
existing activities? I suspect not. And yet you insist that ACD could
not have designed a violin from studying the activities of playing
viola.

Earlier in this thread, when writing about reading Don's article, you
wrote:

AJ> I actually got a bit angry while reading it.

Emotional reaction is not validation. It is often a sign that emotion
has already wreaked havoc on one's thought process. You may want to
re-read Don's article and put aside any emotional reactions. That may
help to eliminate polarization.
