Crossmodal Ambient Displays
Ambient displays have for some time been proposed as a means of providing situated information to users in public spaces in a manner that minimizes the invasive nature of traditional displays, and reduces the distraction caused to bystanders. We explicitly address these shortcomings and present a novel information display framework called a crossmodal ambient display. CrossFlow is a crossmodal ambient display prototype for indoor navigation, that exploits aspects of crossmodal cognition in providing users with the facility to decode temporally multiplexed information in an animated ambient display. We describe a number of benefits of crossmodal ambient displays relating to both privacy and performance. Initial user studies have demonstrated that, compared to traditional navigation aids such as maps, crossmodal displays have the potential to significantly enhance the navigation performance of users whilst at the same time leading to a reduction on the cognitive load imposed by tasks such as navigation.
