Designing Self-Reflective Visualizations in Patient-Cantered Systems

Designing online help systems for reflective users

Empirical studies have revealed that most users are dissatisfied with current help systems. One of the causes for many of the problems found in help systems is a lack of coupling between the process for creating online help and the human-computer interaction design of the application. In this paper, we present a method for building online help based on design models according to a Semiotic Engi...

Designing Educationally Effective Algorithm Visualizations

Despite the intuitively compelling adage " a picture is worth a thousand words, " attempts over the past decade to use animations to explain algorithms to students have produced disappointing results. In most cases interesting algorithm animations were designed, but no formal, systematic evaluations were conducted. When such evaluations were performed the results were mixed, with compelling evi...

Designing Visualizations for Biological Data

Visualization is now a vital component of the biological discovery process. In this article I present visualization design studies as a promising process for creating effective, visualization tools for biological data. The field of biology has been transformed over the last decade with the rapidly decreasing cost of data. Today, the focus is on combining huge genomics databases with large amoun...
