Artificial intelligence methods in the visualization problem of three-dimensional space scenes

September 1994

A method is described for representation and construction of a three-dimensional space scene graphical image on the basis of approximate space reasonings. The method is realized in the frame of the system ″text-figure″ intended for visualization of text descriptions on a natural language of the real world scenes. There are considered solutions of the following problems: description of graphical ... [Show full abstract] objects in the object base, description of fuzzy space relations, construction of a graphical image of the three-dimensional scene on the basis of approximate space reasonings, construction of a graphical planner, construction of a system visualizer, construction of a graphical object base on the basis of a graphical system editor.

Latence d'une réponse graphique à des termes généraux et spécifiques

January 1979 · L?Année psychologique

Michel Denis

Des sujets adultes ont fourni une illustration graphique en reponse a des termes de differents niveaux categoriels. Pour les termes generaux qui recouvrent des classes d'objets presentant les unes par rapport aux autres une grande similitude figurative (arbre, oiseau, poisson, etc.), la latence des reponses est a peu pres equivalente a celle des reponses a des termes plus specifiques. Pour les ... [Show full abstract] termes generaux qui recouvrent des classes d'objets presentant, du point de vue figuratif, de nombreuses caracteristiques distinctives (jouet, meuble, legume, etc.), la latence des reponses est significativement plus grande que celle des reponses a des termes plus specifiques. L'analyse des resultats permet de conclure que des representations imagees sont directement disponibles pour la premiere sorte de termes generaux, tandis que les seconds, designant des concepts depourvus de qualites figuratives, ne peuvent etre illustres qu'a travers la recherche d'une classe conceptuelle plus specifique.

Legends as a Device for Interacting with Visualizations

January 2002

Users and developers of visualization tools must deal with the problem of specifying what information to show and how to represent it. Typically, the user's focus of interest will change over time, and the specifications must change with the user's interests. Techniques for the simple, direct, and intuitive creation and refinement of these specifications can be useful. In this paper we show how ... [Show full abstract] legends, a natural element of graphical displays, may be used as a direct and unobtrusive interaction device through which users may interactively specify new visualizations and animations.
