'I'm waiting where we met last time'

摘要

In light of recent attempts to design location-based mobile services, we present findings from a study of the ways in which positioning is done in everyday talk over the mobile phone. We show that a location is more than a coordinate on a map, and give examples of how people formulate location in a number of different ways according to the particulars of the activity. Based on these findings, we argue that rather than delivering location information in the form of geographical coordinates, location-based services should describe location in ways relevant to the users, thereby supporting the existing positioning practice.
