Felix von Reischach · Repository for Publications and Research Data (ETH Zurich) · 2010
When shopping for consumer goods like wine, digital cameras, and olive oil, people are frequently overwhelmed by the vast amount of choices they are offered.At the same time, they take a decision under uncertainty, since they cannot experience products before buying them.Product reviews created by peer consumers provide a 'virtual experience' and can thus help consumers to take better-informed buying decisions.This dissertation designs, implements, and evaluates a concept for reviewing products via mobile phone.Designing the concept, special attention is paid to its usability.The key usability challenges are the intuitive identification of products, i.e., 'telling' the phone what product is on hand, and the representation of reviews on mobile phones.As a technique for product identification, scanning so-called NFC tags is preliminary selected.To accommodate the limited capabilities of mobile phones regarding information entry and display, a rating concept based on user-generated rating criteria is suggested.
