The disruptive nature of smartphone notifcations and their negative impact on users' productivity are well documented. The majority of these results either originate from controlled laboratory studies, or protocols relying on subjective self-reporting, reducing their ecological validity. This paper presents results from a full day in situ study investigating the impact of perceiving one's smartphone notifcations on wrist motion patterns. Through this objective behavioral assessment, we document
more » ... for the frst time the manifestations of notifcation-induced disruption outside of the lab, independently of user activity and without the need for self-reporting. We identifed a decrease in wrist motion activity following the presentation of a notifcation while the participant was engaged in higher intensity activities, independently of whether the notifcation is immediately attended to. These fndings provide objective support for the claim that notifcations have as much potential for disruption when merely perceived as they do when the user actually responds to them.
