ABSTRACT
Being interrupted by notifications and reminders is common while working. In this study we consider whether system politeness reduces (negative) effects of being interrupted by system requests. We carried out a 2 (polite vs. neutral system request) x 2 (high vs. low mental load) between-participants experiment. We measured annoyance, frustration and mental effort. Our results suggest that social strategies can mitigate some of the negative effects, but that this depends on the difficulty of the task. We discuss the implications of these results for the design of interruptive system messages and for further research into social computing.

Investigating the effectiveness of mental workload as a predictor of opportune moments for interruption
CHI EA '05: CHI '05 Extended Abstracts on Human Factors in Computing SystemsThis work investigates the use of workload-aligned task models for predicting opportune moments for interruption. From models for several tasks, we selected boundaries with the lowest (Best) and highest (Worst) mental workload. We compared effects of ...
Workload Alerts—Using Physiological Measures of Mental Workload to Provide Feedback During Tasks
Feedback is valuable for allowing us to improve on tasks. While retrospective feedback can help us improve for next time, feedback ‘in action’ can allow us to improve the outcome of on-going tasks. In this article, we use data from functional Near ...
Two Sides of the Same Coin: Software Developers' Perceptions of Task Switching and Task Interruption
EASE '18: Proceedings of the 22nd International Conference on Evaluation and Assessment in Software Engineering 2018In the constantly evolving world of software development, switching back and forth between tasks has become the norm. While task switching often allows developers to perform tasks effectively and may increase creativity via the flexible pathway, there ...
