We studied what notifications 15 mobile phone users received during one week, how they attended to them, and how the notifications affected them.
Highlights of our findings are:
* our participants dealt with more than 60 notifications per day, mostly from messengers, SMS, and email.
* Notifications from messengers are largely attended within minutes.
* Notifications from email clients and messengers show significant correlations with people's emotions: emails are associated with interruption and stress. Messages are related to feeling overwhelming but also connected to others.
The paper received best-paper award at ACM MobileHCI '14, which was held in September 2014 in Toronto, Canada.
