Abstract: A user interface system for exploratory search and media discovery includes a display unit with a specific geometrical grid for the visualization of multidimensional interrelations among media items and includes a processing unit programmed to distribute and map media items to the grid coordinates. A method includes user interaction with the user interface system for exploratory browsing, with the users interacting with the visualization grid based on an extension of the focus-plus-context principle for a fluent browsing process. A further method includes generating the specific grid on the display unit.

Abstract: A great difficulty, for example, is to arrange and display inconsistent and uncontrolled metafiles having weak structures, as they are found on YouTube, for example. This is due, among other things, to the fact that no uniform ontology or editorial processing of the metafiles is provided for. In addition, it is also not possible to produce algorithmically generated consistent ontologies. The invention therefore relates to a navigation device for arranging entities in a data space, wherein the navigation device comprises a distribution unit and a display unit, and the display unit shows a rigid, geometrical grid, wherein the distribution unit determines and displays preferential entities. In this way, the chaos in the metafiles is removed by structuring, and navigation in the data space is enabled.
