ThisOrThat: Social Mobile Shopping
Abstract
ThisOrThat is a mobile application for social shopping that leverages social networks to empower users in making more informed everyday decisions. Users describe topics they are interested in and assign to each a group of friends whose opinion is valuable on that particular topic. During shopping, users can instantly create surveys on their mobile phone to gather friends' opinions on a decision. ThisOrThat is supported by a dynamic reputation and trust system that evolves according to the comments and opinions that every participant submits.
