Public exhibits or displays are widely used to present information in public and semipublic places. Users may pass by several of these and observe a significant amount of interesting content, much of which may be forgotten. Unfortunately, there is no widely adopted way for users to acquire related information in locale for their subsequent perusal. We present ContentCascade, a mechanism that allows users to implicitly download various levels of detail of summary information about the content available at the public displays to their personal devices. It also naturally and informally enables users to trade off quality of summary information with presence time. This way, ContentCascade can potentially enhance the overall user experience with public displays as users can recall the summary information later.
Date of Conference: 22-26 Aug. 2004
