users' needs for social tagging and sharing on mobile contacts
In this paper we describe our research toward improving the current mobile contacts applications, which we found to lack important features that are essential to a fully satisfactory user experience. We identify the needs for a better user experience for organizing and searching, as well as looking for information from one's social network. We present the results of a user study that identified the problems with the current mobile contacts applications and propose tagging contacts and social network information sharing as the mechanism for improving their usability and usefulness.
