“…Other systems that retrieve images or other kinds of artwork (such as sculptures, pottery, and so on), have used 3D mainly for visualization purposes. In other work [7][8][9] results of a user query were arranged in a 3D environment to enable the fruition of artwork in the same way as the user is accustomed to in real museums. Both approaches provide a dynamic creation of the scene, depending on the results of the query.…”

Interaction paradigms based on 3D interfaces and virtual reality offer new possibilities to overcome the limitations of query by example. We present a system that lets users navigate a 3D world where they can take photographs to query a database of images by content. Furthermore, users can interactively customize the virtual world by adding objects to the scene and editing object properties such as colors and textures. T he emergence of multimedia technology and the possibility of sharing and distributing image data through largebandwidth computer networks have contributed to an increase of visual data in the global information exchange. Significant advances have been made in the development of efficient compression techniques, but techniques that enable efficient retrieval by content of visual data remain an active research topic. Recently, researchers have developed new tools and interaction paradigms to search for visual information by referring directly to its content. Visual elements such as color, texture, shape, structure, and spatial relationships serve as clues for retrieving images with similar content. The most successful and commonly employed querying interfaces rely on query-by-example paradigms. These paradigms require users to sketch, either from scratch or using prototype images, the content of the image they're looking for. Although it's easy to create simple examples, producing significant examples of complex scenes remains a difficult task. The photographer's metaphor presented in this article facilitates authoring complex examples. Actually, the user takes a photograph of a (customizable) 3D environment rendered by the system. Since the system renders the environment, the paradigm's effectiveness doesn't rely on the user's painting abilities.

“…In client-server-based interactive information visualization user interfaces (see, e.g., [LHN99], [MLHN99], [RLHA98], [MSSNHPL98]), data sets of many types are made accessible by a server. Users request such data sets and client user interfaces visualize them applying a given information visualization mapping.…”

In client-server based interactive infonnation visualization, user interfaces data sets of many types are made accessible by a server. On the server side, these data sets can, e.g., be stored in a file system. As soon as a user requests the data set, it will be transmitted from the server to the requesting client. A different approach is to dynamically construct a data set at request time on the server side for visualization on the client side. Another approach for database driven infonnation visualization is to request actual data out of a running infonnation visualization application on the client side. Both visualization methods have in common that changes in the underlying data cannot be automatically reflected in changes of the client's infonnation visualization state and context. A solution for this problem is the use of database triggers which today are often implemented in existing database management systems (DBMS). Database triggers are a mechanism used to define a set of operations which are to be executed by the DBMS as soon as a given part of the data in the database changes. Using triggers to update an infonnation visualization client has the advantage of eliminating unnecessary database requests. Moreover, the delay in updating the infonnation visualization on the client side is only dependent on the time it takes to send a message from the server to the client. This paper describes a conceptual model for such a trigger mechanism and evaluates some upcoming problems. Furthennore, the paper describes a prototypical proof-of-concept implementation based on commonly used technologies and systems. H. Arisawa et al. (eds.), Advances in Visual Information Management

Supporting collaborative multimedia content management activities, as e.g., image and video acquisition, exploration, and access dialogues between naive users and multi media information systems is a non-trivial task. Although a wide variety of experimental and prototypical multimedia storage technologies as well as corresponding indexing and retrieval engines are available, most of them lack appropriate support for collaborative end-user oriented user interface front ends. The development of advanced user adaptable interfaces is necessary for building collaborative multimedia information-space presentations based upon advanced tools for information browsing, searching, filtering, and brokering to be applied on potentially very large and highly dynamic multi media collections with a large number of users and user groups. Therefore, the development of advanced and at the same time adaptable and collaborative computer graphical information presentation schemes that allow to easily apply adequate visual metaphors for defined target user stereotypes has to become a key focus within ongoing research activities trying to support collaborative information work with multimedia collections.
