ExplorationWall is a touch-based search user interface that allows incremental exploration and sense-making of large information spaces by combining entity search, flexible use of result entities as query parameters, and spatial configuration of search streams that are visualised for interaction. Entities can be flexibly reused to modify and create new search streams, and manipulated to inspect their relationships with other entities.
