A Theory-Based Approach for a Modular System of Interactive Decision Aids

In web stores, a large amount of product information is easily available for consumers. This often leads to information overload on the consumer-side which decreases user-satisfaction and can cause purchase deferral. Therefore, our goal is to prevent consumers from information overload by supporting the cumbersome process of comparing and evaluating products. We propose easy to understand, interactive decision aids, called interactive information management tools such as filtering, sorting and scoring. The contribution of this paper is to (1) retrieve guidelines for designing such tools from both literature on decision behavior research and information systems, and (2) build a prototype following these guidelines. The prototype is evaluated in two usability studies
