Users of digital devices are increasingly confronted with a tremendous amount of notifications that appear on multiple devices and screens in their environment. Today many users own different ubiquitous devices such as a smartphone, a tablet, a notebook and a smartwatch. If an email client is installed on every device an incoming email produces up to four notifications - one on each device. In the future, we will receive notifications from an increasing number of ubiquitous devices. Therefore, we need smart attention management for incoming notifications as well as novel ways to present and interact with notifications. One way for a less interrupting attention management could be the use of ambient representations of incoming notifications. This workshop brings together researchers and practitioners from academia and industry to explore how the flood of notifications on different computing devices and in smart environments can be managed, to avoid information overload.
