User Controlled Overviews of an Image Library: A Case Study of the Visible Human
MetadataПоказать полную информацию
This paper proposes a user interface for remote access of the National Library of Medicine's Visible Human digital image library. Users can visualize the library, browse contents, locate data of interest, and retrieve desired images. The interface presents a pair of tightly coupled views into the library data. The overview image provides a global view of the overall search space, and the preview image provides details about high resolution images available for retrieval. To explore, the user sweeps the views through the search space and receives smooth, rapid, visual feedback of contents. Desired images are automatically downloaded over the Internet from the library. Library contents are indexed by meta-data consisting of automatically generated miniature visuals. The interface software is completely functional and freely available for public use at: http://www.nlm.nih.gov/.
