Evaluating the effectiveness of interactive map interface designs: a case study with eye movement analysis


Coltekin, Arzu; Garlandini, S; Heil, B; Fabrikant, Sara I (2008). Evaluating the effectiveness of interactive map interface designs: a case study with eye movement analysis. In: AutoCarto 2008, Shepherdstown, West Virginia, US, 8 September 2008 - 11 September 2008, 1-12.

Abstract

This paper proposes combining traditional usability methods with the analysis of eye movement recordings to evaluate interactive map interfaces, and presents a case study in support of this approach. This case study evaluates of two informationally equivalent but differently-designed online interactive map interfaces presented to users. In a mixed factorial experiment thirty participants were asked to solve three typical map use tasks using one of the two interfaces, while we measured user Satisfaction, Efficiency (completion time) and Effectiveness (accuracy) with standard SEE usability metrics. While traditional (bottom line) usability metrics can reveal a range of usability problems, they may be enhanced by additional procedural measures such as eye movement recordings. Eye movements have been shown to reveal the amount of cognitive processing a display requires and where these cognitive resources are required. Therefore, we can establish how a display may or may not facilitate task completion by analyzing eye movement recordings. User satisfaction information related to stimuli (i.e., collected through standardized questionnaires) can also be linked to eye tracking data for further analysis. We hope that the presented methodology and case study will help cartographers and map interface designers to better identify design issues in their products, and that these insights will eventually lead to more effective and efficient online map interfaces.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
