The high number of products available makes it difficult for a user to findthe most suitable products according to their needs. This problem is especiallyexacerbated when the user is trying to optimize multiple attributes duringproduct selection, e.g. memory size and camera resolution requirements in caseof smartphones. Previous studies have shown that such users search extensivelyto find a product that best meets their needs. In this paper, we propose aninterface that will help users in selecting a multi-attribute product through aseries of visualizations. This interface is especially targeted for users thatdesire to purchase the best possible product according to some criteria. Theinterface works by allowing the user to progressively shortlist products andultimately select the most appropriate product from a very small considerationset. We evaluated our proposed interface by conducting a controlled experimentthat empirically measures the efficiency, effectiveness and satisfaction of ourvisualization based interface and a typical e-commerce interface. The resultsshowed that our proposed interface allowed the user to find a desired productquickly and correctly, moreover, the subjective opinion of the users alsofavored our proposed interface.
