In this paper, we describe how a user's location history (recorded by tracking the
user's mobile device location with his permission) is used to extract the user's
location patterns. We describe how we compute the user's commonly visited places
(including home and work), and commute patterns. The analysis is displayed on the
Google Latitude history dashboard  which is only accessible to the user.
