No, I still think something needs to be said about it. I prefer “Approaching collapse”, because it says something about the nature of the task. What I mean, and what I think is essential to describe is, that there is a failure that is closing in on us, and the point is that it does not occur instantly. The delay is key. This time delayed failure is what we make use of, as we can control one task when another is approaching a collapse, and change our attention to it before said collapse occurs. This change then also function as a trigger, to set our other task going towards its collapse. This is not conveyed when the term “problem” is used. “Approaching collapse” tells us that there is an potential failure in the future that we is closing in on us, but it is not instant.
The opportunity of attention sharing, of two (or more) tasks (such as catching an object that has been thrown) by one or more instruments of control (such as a hand), is the essence of what we are trying to describe. A shift of attention triggers a new approaching collapse, in a cyclical, unbroken chain of events.
What I meant was that perhaps I have been focusing too much on the aspect of an approaching collapse, when the essential property is the shifting of attention to control, and that each shift triggers a new situation in need of attention, cyclicly.
Both aspects are needed in our description, I think.
In terms of multiplexes, I think the game is, that as long as there is at least one approaching collapse still active, it can trigger a new release, thus keeping the cycle unbroken.
The definition for The juggling phenomenon would then be:
A number of tasks that each can exist in the states of control or approaching collapse.
There always needs to be at least one approaching collapse active, so that when attention is set to it, that releases the attention of another task. If all of this happens in an unbroken cycle, that is the juggling phenomenon.
A definition for the specific activity of juggling then becomes:
The version of the juggling phenomenon, where the task is throwing and catching objects using the hands, and the approaching collapse is more than two objects in a hand, or dropping.
