We report from the Do Not Disturb Challenge where 30 volunteers disabled notification alerts for 24 hours across all devices. The effect of the absence of notifications on the participants was isolated through an experimental study design: we compared self-reported feedback from the day without notifications against a baseline day. The evidence indicates that notifications have locked us in a dilemma: without notifications, participants felt less distracted and more productive. But, they also felt no longer able to be as responsive as expected, which made some participants anxious. And, they felt less connected with one's social group. In contrast to previous reports, about two third of the participants expressed the intention to change how they manage notifications. Two years later, half of the participants are still following through with their plans.
Distraction & Productivity Impairment Since people receive plenty of notifications, by sheer probability, notifications are bound to appear from time to time while the receiver is busy with other tasks. Since people usually attend to notifications within minutes, notifications may sometimes interrupt those other tasks. Such interruptions can have negative effects: previous work in the context of information workers has found that notifications negatively affect work efficiency when delivered in the middle of a work task @cite_39 @cite_20 @cite_40 @cite_27 @cite_21 @cite_1 @cite_0 , and the effect is more pronounced when the task is cognitively demanding @cite_7 @cite_5 . As found by Stothart @cite_0 , this is even true when the notification is not attended, as tested in a controlled exam setting. Hence, previous work consistently highlights the disruptive effects of notifications in work settings. Mobile phone users also expressed to frequently feel interrupted by notifications, even outside of work settings @cite_19 . We hypothesize that the absence of notifications will have positive effects on productivity.

Notifications are the mechanism that mobile applications utilize to let users know that a new message, email, call or similar has been received. Notifications may make a sound, a vibration or modify the app icon in some way. They may make us stop what we are doing, thus interrupting us and having a negative effect on our work. Before defining a cause-effect relation between notifications and their impact on the users' current tasks, first we have to study how users manage notifications. This paper describes the results of a survey on how users react when they receive a notification. The results of this descriptive research show how people are moving from sound to visual notifications, which reflects the ability of people to adapt to new technologies. Notifications on mobile phones alert users about new messages, emails, social network updates, and other events. However, little is understood about the nature and effect of such notifications on the daily lives of mobile users. We report from a one-week, in-situ study involving 15 mobile phones users, where we collected real-world notifications through a smartphone logging application alongside subjective perceptions of those notifications through an online diary. We found that our participants had to deal with 63.5 notifications on average per day, mostly from messengers and email. Whether the phone is in silent mode or not, notifications were typically viewed within minutes. Social pressure in personal communication was amongst the main reasons given. While an increasing number of notifications was associated with an increase in negative emotions, receiving more messages and social network updates also made our participants feel more connected with others. Our findings imply that avoiding interruptions from notifications may be viable for professional communication, while in personal communication, approaches should focus on managing expectations. We describe a study on the influence of instant messaging (IM) on ongoing computing tasks. The study both replicates and extends earlier work on the cost of sending notifications at different times and the sensitivity of different tasks to interruption. We investigate alternative hypotheses about the nature of disruption for a list evaluation task, an activity identified as being particularly costly to interrupt. Our findings once again show the generally disruptive effects of IM, especially during fast, stimulus-driven search tasks. In addition, we show that interruptions coming early during a search task are more likely to result in the user forgetting the primary task goal than interruptions that arrive later on. These findings have implications for the design of user interfaces and notification policies that minimize the disruptiveness of notifications. Desktop notifications are designed to provide awareness of information while a user is attending to a primary task. Unfortunately the awareness can come with the price of disruption to the focal task. We review results of a field study on the use and perceived value of email notifications in the workplace. We recorded users' interactions with software applications for two weeks and studied how notifications or their forced absence influenced users' quest for awareness of new email arrival, as well as the impact of notifications on their overall task focus. Results showed that users view notifications as a mechanism to provide passive awareness rather than a trigger to switch tasks. Turing off notifications cause some users to self interrupt more to explicitly monitor email arrival, while others appear to be able to better focus on their tasks. Users acknowledge notifications as disruptive, yet opt for them because of their perceived value in providing awareness.
