Human Interrupts

In computer speak, an interrupt is a signal from hardware or software indicating the need for attention. There are two different types of interrupts: Asynchronous (random), and synchronous (predictable). People also have interrupts. All human interrupts are asynchronous unless otherwise noted.

  • Pain.
  • Biological needs (synchronous).
  • Strong external stimuli.
  • Doorbell, phone, pager, or any other real-time device that someone else uses to get your attention.
  • A sudden thought, a flash of insight, or intuition.
  • An alarm or timer (synchronous).
  • A stop sign or stop light (synchronous).
  • Anything that blocks or stops what you were doing for a long time.
