Review: Media Enhanced input/output Metaphors

Abstract

The key to content-based access of multimedia information is to discover, encode and maintain the associations among media objects. Media enhanced interaction metaphors employ multiple paradigms to facilitate the discovery, encoding and maintenance of these associations. Although the metaphors themselves may be conceptual, their effective incorporation into the user interface for multimedia information access often requires the use of visual querying mechanisms. To access multimedia information by content, various query mechanisms need to be combined, and the user interface should be visual as much as possible and also enable visual relevance feedback, user-guided navigation and user-controlled discovery of new associations.
