Viewing personal history records: A comparison of tabular format and graphical presentation using LifeLines

Abstract

Thirty-six participants used a static version of either LifeLines, a graphical interface, or a Tabular representation to answer questions about a database of temporal personal history information. Results suggest that overall the LifeLines representation led to much faster response times, primarily for questions which involved interval comparisons and making intercategorical connections. A “first impression” test showed that LifeLines can reduce some of the biases of the tabular record summary. A post-experimental memory test led to significantly (p<.004) higher recall for LifeLines. Finally, simple interaction techniques are proposed to compensate for the problems of the static LifeLines display’s ability to deal with precise dates, attribute coding and overlaps.
