What's interrupting your search?

Web search is a common activity in mobile context. However, the nature of performing tasks environment means there risk interruption. While effects interruptions on have been studied recent years, such occurring real-world settings not. Using diary study approach, we collected data from 20 participants everyday they faced conducting web searches over 10-day period. We used inductive open coding to categorise assigning each interruption category/sub-category combination. then deductive approach classify as being either internally or externally-induced; and non mobile-specific. found broad range interruptions, which organised into an extensive taxonomy. Further, substantial proportion are externally-induced more than half unique contexts. The empirical evidence our findings provide insight complex search, information upon base future studies (e.g., surveys, controlled laboratory studies), motivation for interface designs that can help mitigate interruptions.
