Yet, beyond showing how the data are spatially distributed, dot maps are often visually cluttered in terms of consistency, overlap, and representativeness. Existing clutter reduction techniques like jittering, refinement, distortion, and aggregation also address this issue, but do so by arbitrarily displacing dots from their exact location, removing dots from the map, changing the spatial reference of the map, or reducing its level of detail, respectively. We present BinSq, a novel visualization technique to compare variations in dot density patterns without visual clutter. Based on a careful synthesis of existing clutter reduction techniques, BinSq reduces the wide variety of dot density variations on the map to a representative subset of density intervals that are more distinguishable. The subset is derived from a nested binning operation that introduces order and regularity to the map. Thereafter, a dot prioritization operation improves the representativeness of the map by equalizing visible data values to correspond with the actual data. In this paper, we describe the algorithmic implementation of BinSq, explore its parametric design space, and discuss its capabilities in comparison to six existing clutter reduction techniques for dot maps.

The effect of aesthetic on the usability of data visualization / Nick Cawthon (04/07/2007)    

Public Titre : The effect of aesthetic on the usability of data visualization Type de document : Article/Communication Auteurs : Nick Cawthon, Auteur ; Andrew Vande Moere, Auteur Editeur : New York : Institute of Electrical and Electronics Engineers IEEE Année de publication : 04/07/2007 Conférence : IV 2007, 11th IEEE International Conference Information Visualization 04/07/2007 06/07/2007 Zurich Suisse Proceedings IEEE Importance : 9 p.

This paper investigates the results of an online survey of 285 participants, measuring both perceived aesthetic as well as the efficiency and effectiveness of retrieval tasks across a set of 11 different data visualization techniques. The data visualizations represent an identical hierarchical dataset, which has been normalized in terms of color, typography and layout balance. This study measured parameters such as speed of completion, accuracy rate, task abandonment and latency of erroneous response. Our findings demonstrate a correlation between latency in task abandonment and erroneous response time in relation to visualization's perceived aesthetic. These results support the need for an increased recognition for aesthetic in the typical evaluation process of data visualization techniques.

A conceptual model for evaluating aesthetic effect within the user experience of information visualization / Nick Cawthon (2006)

Public Titre : A conceptual model for evaluating aesthetic effect within the user experience of information visualization Type de document : Article/Communication Auteurs : Nick Cawthon, Auteur ; Andrew Vande Moere, Auteur Editeur : New-York : IEEE Computer society Année de publication : 2006 Conférence : IV 2006, 10th IEEE International Conference Information Visualization 05/07/2006 07/07/2006 Londres Royaume-Uni Proceedings IEEE Importance : pp 374 - 382 Format : 21 x 30 cm Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] modèle conceptuel de données [Termes IGN] traitement automatique de données [Termes IGN] utilisateur [Termes IGN] visualisation cartographique [Termes IGN] visualisation de données Résumé : (Auteur) This paper proposes a conceptual model for which one might begin to assess aesthetic effect within the user experience of information visualization. Through first defining, then illustrating new dimensions of aesthetic that exist within the context of information visualization, this paper goes on to suggest that a user centered evaluation method not solely centered around task efficiency metrics is now imperative.
