Visualization experience and related process modeling
The visualization process is a transformation of information content into knowledge via a visual representation. Visualization experience, proposed herein, reflects human sensations arising during the visualization process. It provides a basis in which ...
Interpretation of strokes in radial menus
Most of the recently proposed text entry methods for touch screen devices are stroke-based: the traditional tapping interaction is being replaced with a more natural gesture, performed through a pointer (pen or finger) on a soft keyboard. These methods ...
Cognitive artifacts as a window on design
We are investigating information analysis as a kind of problem solving in which teams are presented with a collection of facts regarding people, places and events, and then identify underlying connections, patterns, and plans in order to draw specific ...
Improving multiple aesthetics produces better graph drawings
Many automatic graph drawing algorithms implement only one or two aesthetic criteria since most aesthetics conflict with each other. Empirical research has shown that although those algorithms are based on different aesthetics, drawings produced by them ...
On the expressiveness of spider diagrams and commutative star-free regular languages
Spider diagrams provide a visual logic to express relations between sets and their elements, extending the expressiveness of Venn diagrams. Sound and complete inference systems for spider diagrams have been developed and it is known that they are ...
Exploring hierarchical multidimensional data with unified views of distribution and correlation
Data analysts explore data by inspecting features such as clustering, distribution and correlation. Much existing research has focused on different visualisations for different data exploration tasks. For example, a data analyst might inspect clustering ...
