Information distance and orientation in liquid layout

Published: 06 April 2008 Publication History

Abstract

Liquid layout of web browser elements enables enterprise applications to adapt to larger windows on larger displays, but guidelines are needed to define layout rules for widescreen page content. The present study considers the impact of relative portlet distance and orientation in enterprise-type tasks. Eighteen analysts completed tasks in which critical information was located in two portlets separated by defined distances and orientations. Analysis of completion times, assists, errors, and subjective scales revealed a significant advantage for wider, horizontal information layouts over narrower, vertical layouts. The difference persisted, even when accounting for the influence of vertical scrolling. Horizontal layout in these dashboard-style tasks had a 5%-25% time savings over vertical layout, as separation distances increased to 2000 pixels. Differences in horizontal and vertical eye movement accuracy and velocity could account for these results. Widescreen design guidelines should include a preference for horizontal layout as horizontal screen distances increase.
