A computational system is provided that includes: (a) a boundary analyzer 164, 168, and 216 operable to identify a next boundary in a predetermined activity; and (b) an interrupt handler 160 operable to (i) determine that a notification is to be provided to a user, (ii) determine that the user is currently engaged in the predetermined activity on a computational device, and (iii) provide the notification to the user in temporal proximity to the identified next boundary.
