Original title / Originaltitel Immersive Information Spaces for Data Access and Dissemination
Summary / Zusammenfassung Exponentially growing data archives emphasize the need for efficient techniques and novel approaches to find and extract information. Information visualization has emerged in the Information Retrieval domain to facilitate access to large databases. This development acknowledges the need to focus on higher level cognitive processes in information seeking. Graphic depictions of large databases are increasingly based on the spatial metaphor. These representations are also known as spatialized views or information spaces.
This study will provide an experimental testbed for the immersive representation of a very large data archive based on spatial metaphors. This information space will allow information seekers to efficiently access NIMA’s vast geospatial data collections. The research methodology of this study will include: (1) information needs assessment of customers and national security data providers (2) cyclic design and empirical evaluation of an immersive, three-dimensional information space, based on NIMA’s data repositories (3) cyclic design and evaluation of alternative immersive spatialization solutions, and (4) redesign of immersive information space components based on a final usability evaluation.
The final product of this investigation will be a proof-of-concept demonstration of an immersive information space based on a sound methodological and conceptual framework of spatial metaphors and human centered computing. One of the particular strengths of this proposal is the uniqueness of the interdisciplinary approach: Researchers from Geographic Information Science, Library and Information Science, and Computer Science will be collaborating to produce new ways of indexing (in that metadata produced by automatic and semi-automatic techniques as well as metadata assigned by human experts will be combined in a single record), viewing and visualizing, accessing, evaluating, as well as exploring and using NIMA’s geospatial data repositories. The final product will allow government agencies to more efficiently exploit their fast growing imagery and geospatial data collections. The concepts proposed and methods applied for this investigation are generic enough to be applicable to any domain within a national information infrastructure.
