Excentric Labeling: Dynamic Neighborhood Labeling for Data Visualization

Abstract

The widespread use of information visualization is hampered by the lack of effective labeling techniques. A taxonomy of labeling methods is proposed. We then describe "excentric labeling", a new dynamic technique to label a neighborhood of objects located around the cursor. This technique does not intrude into the existing interaction, it is not computationally intensive, and was easily applied to several visualization applications. A pilot study indicates a strong speed benefit for tasks that involve the rapid exploration of large numbers of objects. Also cross-referenced as UMIACS-TR-98-59
