Visual rating system for HFES graphics: Design and analysis
This paper introduces research that evolved out of an analysis of Gillan, Wickens, Hollands, & Carswell’s (1998) guidelines for the graphical presentation of quantitative data in HFES publications. The impetus for this research stemmed from a concern about substandard illustrations accompanying publications and the difficulty in communicating how to improve the quality of those illustrations. The aim in this paper is twofold: (1) to offer a pragmatic method for operationalizing and measuring the adherence of a specific graphic to the aforementioned guidelines; and (2) to present the analysis of preliminary data gathered using the metric developed. I will first present the methodology used to develop a Web-based rating interface, then examine the implementation of that interface, and finally discuss the results of a comparative analysis performed on samples of graphics published before and after the original guidelines. Counterintuitively, the only evidence we found of a change between graphs published before the guidelines and those published after was a decrease in the readability of text.
