Transitions between activities occur throughout the day, often with little notice. Moving from one task to another, or from activity to rest, introduces a brief period where attention, posture, or pace shifts.

These moments are typically short, but they can be distinct. Transitions mark the boundary between what has just ended and what is about to begin, even when the change itself is subtle.

Transitions do not always involve interruption. In many cases, they happen gradually, shaped by context rather than intention. Their presence becomes most apparent when a transition is delayed, repeated, or unexpectedly altered.
