A Graphical Shopping Interface Based on Product Characteristics

Most recommender systems present recommended products in lists to the user. By doing so, much information is lost about the mutual similarity between recommended products. We propose a graphical shopping interface, which represents the mutual similarities of the recommended products in a two dimensional space, where similar products are located close to each other and dissimilar products far apart. The graphical shopping interface can be used to navigate through the complete product space in a number of steps. We will show a prototype application of the system for MP3-players.
