    Abstract: The selection of appropriate display technology and interaction techniques relies upon an understanding of the public-private nature of information and the spaces from which it is accessed. We propose a crossmodal ambient display framework that supports multiple users simultaneously accessing in-formation which contains both public and personal elements. Crossmodal ambient displays are multi-user interfaces that facilitate the efficient public access of personalized information, while maintaining the anonymity of each user in physical public spaces. Based on psychological theories of crossmodal attention which characterize human capabilities for matching information picked up by different modalities, the framework takes advantage of both public displays and mobile devices through the use of peripheral cues, and makes possible the integration of multi-task performance and information personalization in public space.
