Empirical Validation of a Computer-Mediated Coordination of Interruption
نویسنده
چکیده
User’s cognitive state is extremely fragile and sensitive to external interruption, especially when a user is performing a cognitively-taxing task. Given that interruptions frequently occur during human-computer interaction, and given the relative scarcity of human attention and their vulnerability to interruptions, interruption-resistance is needed to be considered when designing user interfaces. The main objective of this research has been to explore the possibility of facilitating user’s performance in a context of interruption, by employing a context-sensitive computer-mediated coordination of interruption. A novel Interruption Taxonomy, which synthesizes various kinds of interruption-related context information, served as a basis for implementing graceful coordination of interruption. An exploratory user study was conducted to experimentally evaluate the adequacy of the proposed approach for mediating interruptions and the utility of the Interruption Taxonomy.

Recent trends in software development directed toward intelligence, distribution, and mobility have brought sophisticated software artifacts that often come with some unwanted side effects; frequent interruptions, for instance. In general, people are less effective when exposed to interruptions. We have created a framework that helps in selecting the most appropriate timing for interruption as ...
