The Scope is a glanceable notification summarizer. We have designed this simple information visualization tool to help unify notifications and reduce distractions for the user, thus avoiding notification overload. The Scope allows users to remain aware of notifications from multiple sources of information, including e-mail, instant messaging, information alerts, and appointments. The design employs a circular radar-like screen divided into sectors that group different kinds of notifications. The more urgent a notification is, the more centrally it is placed. Visual emphasis and annotation is used to reveal important properties of notifications. Several natural gestures allow users to zoom in on particular regions and to selectively drill down on items.
