A peripheral notification display for multiple alerts: design rationale

This paper presents the design rationale of a notification system based on a peripheral display, able to deliver information with different levels of severity, coming from multiple sources. Though originally conceived for a telecommu-nication management system, the design exhibits a level of abstraction allowing applicability in different contexts, provided that information to be notified satisfy a few basic requirements. The system include a visual coding technique and tran-sitions such that low severity alarms are associated with a few data conveyed in a subliminal way, whereas more urgent alarms are associated with notifications re-quiring focal attention and technical intervention.
