Empirical evaluation of a visual interface for exploring message boards

Abstract

This paper introduces a method that presents a number of characteristics of threads in a discussion forum through graphical illustrations. This technique brings together visual components, such as dimension, color, intensity, and position to present multiple aspects of a thread including the amount of information, popularity, activities, comparative value, and tenure of the thread. This high visual abstraction of threads allows us to display a large number of threads showing overall properties of the contents on a limited screen space. These proposed visualization techniques will assist the user to filtering noisy threads effectively from threads having important features. We have conducted an experimental study, which compares the effectiveness of the developed visual interface to a traditional text-based interface. The experimental study has shown that the user's search speed and accuracy in finding noticeable threads from a huge collection of threads has improved significantly by using the visual navigation tool. © Springer-Verlag Berlin Heidelberg 2006.
