Investigating users’ interruptibility as an indicator of his/her attention status has been essential in recent pervasive computing where the users’ attention resources get scarce against an ever increasing amount of information. We propose the “Interruptibility Map,” a geographical tool for analyzing and visualizing the user’s local interruptibility status in the context of smart city research. Our map describes where citizens are expected to feel more or less interruptive against notifications produced by computing devices, which are known to have adverse effects on work productivity, emotion, and psychological state.
