Collaboration requires people to share \"common ground\", which is the knowledge that enables them to communicate and, more generally, to coordinate their activities. Common ground has been explored in a variety of systems, domains, and disciplines. Of particular interest are the new developments in online social environments (instant messaging, SMS, multiplayer virtual worlds) that have become quite popular. Collaborative information visualization environments can benefit from common ground advances that are not only in the collaborative visualization area but also from advances in online social environments. We expand the notion of common ground for visualization systems based on our experiences with two systems we have developed. CoMotion is a collaborative information visualization environment. Reality Instant Messaging is a system that provides lessons from new interactive online social environments.","PeriodicalId":259374,"journal":{"name":"Proceedings on Seventh International Conference on Information Visualization, 2003.

In relational databases, the high-level view can be described using entity-relationship diagrams, which identify relationships between entities in the data model. Such high-level views are useful for database design activities, and can be used to generate user interfaces for constructing queries. This research introduces techniques for visualizing structural similarity of database queries. We demonstrate that individual queries can be visualized using graph visualization techniques. A distance measure based on query structure is proposed that provides database designers and administrators with a high-level perspective of relationships in the underlying data.","PeriodicalId":259374,"journal":{"name":"Proceedings on Seventh International Conference on Information Visualization, 2003.

An extensive literature survey reveals no journal or conference papers on Amharic character recognition. The Amharic script has 33 basic characters each with seven orders giving 231 distinct characters, not including numbers and punctuation symbols. The characters are cursive but not connected and unlike other cursive scripts do not use dots. We describe the Amharic script and discuss the difficulties of applying conventional structural and syntactic recognition processes. Two statistical algorithms for identifying Amharic characters are described. In both, the characters are normalised for both size and orientation. The first compares the character against a series of templates. The second derives a characteristic signature from the character and compares this against a set of signature templates. The signatures used are fifty times smaller than the original character and the recognition process is corresponding faster but with some loss of accuracy. The statistical techniques described have been fully implemented and the resulting performance outlined.","PeriodicalId":259374,"journal":{"name":"Proceedings on Seventh International Conference on Information Visualization, 2003.

Advanced imaging devices, such as fMRI and PET scans, have provided researchers with visual information in the field of brain science that may settle these debates. We outline a research study conducted among undergraduate art students to investigate the level of visual perception and creative development. The purpose is to gather basic information that would merit further scientific investigation. Among the groups studied, the research concluded that artistic traits such as visual memory, perception and a critical eye for detail declined 80% as compared to research studies conducted in 1944. We present scientific research in the field of cognition and brain science, suggesting dominant use of technology in the arts retards intellectual and perceptual-motor skills.","PeriodicalId":259374,"journal":{"name":"Proceedings on Seventh International Conference on Information Visualization, 2003.

It draws from a Web-based hypermedia doctoral dissertation entitled 'realising the virtual: the Internet as a space for transformatory art practice' which incorporates creative works undertaken as research and praxis. The dissertation addressed the question of the potential of Internet-based new media arts practice, as a form of cultural activism, to effect positive social change. We trace shifts in art's orientation, through computer and telecommunications mediation, from that of 'a work' to that of 'media' (from materiality to temporality); and in its operational mode, from that of the televisual to the telematic (from vision at a distance to data-banking at a distance). A key focus is the evolution of a new genre, 'netArt', the basis for which is critical engagement 'in the mode of information' [Poster, M., (1990)].","PeriodicalId":259374,"journal":{"name":"Proceedings on Seventh International Conference on Information Visualization, 2003.

Mental activities and perceptional interactions of the real world are often interdependent and occur mutually. Cognition is enhanced by the use of the real world, in particular the use of cognitive artifacts or physical inventions (S. K. Card, et al., 1999). We describe the process from perception to information, explain different models of mental representations, and introduce Chi's visualization process. We use these theories and models to introduce and evaluate different visualization tools, which are positioned to explore and navigate a groupware-based organizational memory that is presented as a small case. We point out how the different characteristics and functionalities of these visualization tools contribute to a synergetic match of visual metaphors and cognitive processes.","PeriodicalId":259374,"journal":{"name":"Proceedings on Seventh International Conference on Information Visualization, 2003.

A prototype of aging a specific region of someone's face, which utilizes a framework for facial feature is presented.

Further development of virtual and augmented reality in medicine is moving towards photorealistic rendering and patient specific modeling, permitting high fidelity visual examination and user interaction. This coincides with the current development in computer vision and graphics where image information is used directly to render novel views of a scene. These techniques require extensive use of geometric information about the scene and provide a comprehensive review of the underlying techniques required for building patient specific models with photorealstic rendering. It also highlights some of the opportunities that image based modeling and rendering techniques can offer in the context of minimally invasive surgery.","PeriodicalId":259374,"journal":{"name":"Proceedings on Seventh International Conference on Information Visualization, 2003.
