“…The cost-benefit trade-off between awareness and interruption is a crucial aspect [5]: Interruptions unrelated to the primary task may negatively influence task performance and affective state, leading to longer task completion times, higher error rates, and increased frustration [5][6][7][8] and, on the other hand, studies have proven that when users are offered the possibility of negotiating the receipt of notifications they tend to an indefinite postponement [9], with a resulting inability to get the right information at the right time [7,10,11], which would be highly harmful when the recipient of the notification is expected to be responsible for some relevant action in response. For example, the study discussed in [12] shows how, in a clinical environment, sending digital notifications with reminders of incoming appointments to patients greatly improves the efficiency of health care services by increasing attendance and sensibly reducing the number of "no shows".…”
