abstract = {Notifications and interrupts are closely related. Interruptions might mitigate the performance of its receipt and therefore impede the fulfillment of tasks. Notifications can cause such interruptions. Nowadays, smartphones became ubiquitous. A certain amount of notifications is issued to their users every day.

Previews work focused on identifying opportune moments for the notification delivery at which the adverse effects of an interruption is minimal. Smartphones provide various sensors. The data which these sensors acquire can be used to determine the context of the user. With contextual information more suitable moments for the notification delivery can be found. Snoozing mobile notifications by its recipient was not a popular research target. Motivated to investigate this field we developed a concept for snoozing mobile notifications. Further, we developed a second concept of rules that are capable of acting on incoming notifications automatically. We implemented both concepts in a mobile Android application. Afterward, we conducted two studies to gather data. For the first study, we published our application. We collected snooze behavior data from users all over the world. The second study we conducted was a controlled in-situ user study with 18 participants. 16 participants successfully participated. These participants used an updated version of our application.
