Thank you for participating in this user study. LocaShare is an application that allows you to share your location data in ways that are different from existing services like Foursquare and Latitude.

* place and time-based sharing: you can elect to share your location only when you arrive in certain places, or only during certain times of day or times of the week, without the need to “check-in”
* data browsing / transparency: An important part of the interface is the part that lets you see both data that is shared with you and see the data that you are sharing with others.

Setup: Imagine your name is Katrina, and there are three other users in the system – Scott, Tiffany and Sharon.
