Ludwig answers natural language queries about a simple scenes using a real-time vision system based on current biological theories of vision. Ludwigis unusual in that it does not use a propositional database to modelthe world. Instead, it simulates the interface of a traditional world modelby providing plug-compatible operations that are implementeddirectly using real-time vision. Logic variables are boundto imageregions, rather than complexdata structures, while predicates, relations, andexistential queries are computedon demandby the vision system. This architecture allow Ludwigto "use the world as its own best model" in the most literal sense. The resulting simpfifications in the modeling, reasoning, and parsing systems allow them to be implemented as communicatingfinite state machines, thus giving thema weakbiological plausibility. Theresulting systemis highly pipelined and incremental, allowing noun phrase referents to be visually determinedeven before the entire sentence has been parsed.
