This paper shows how GSR signals can be related to traditional usability metrics. The test case is an e-government Website, enriched with an animated face to help users’ navigation. First, we present the results on the effects of the talking face, which have been assessed with traditional usability metrics in a withingroup experiment. Then, we show how such traditional analyses have correspondence in GSR signals. As the GSR signal is very subjective, its log data must be analyzed with care, in order to have significant and robust results. Applying a differential analysis, the GSR traces supported some findings obtained with traditional usability metrics.

Abstract

This paper shows how GSR signals can be related to traditional usability metrics. The test case is an e-government Website, enriched with an animated face to help users’ navigation. First, we present the results on the effects of the talking face, which have been assessed with traditional usability metrics in a withingroup experiment. Then, we show how such traditional analyses have correspondence in GSR signals. As the GSR signal is very subjective, its log data must be analyzed with care, in order to have significant and robust results. Applying a differential analysis, the GSR traces supported some findings obtained with traditional usability metrics.
