Visual Notifier: A Timeline-Based Visualization for Notifications from Several Environments

In this paper we describe the visual notifier which is a timeline-based visualization that provides an overview about incoming notifications while it also supports an easier way to manage such notifications from several environments. Moreover, it is also possible to link them by certain subject types, author names or groups, or textual content. Such a visualization is in particular useful if there are too many notifications occurring in a short time period to answer and react on immediately, or to keep track of. The interactive visualization is implemented in Java and is easily extendable by additional functionality and interaction techniques. We illustrate theusefulness bytesting itforseveralemailaddresses andmessages from Facebook, Twitter, Ebay, Linkedin, and Researchgate.
