The Whereabouts Clock was a final year project undertaken by Christine Trant and under the supervision of Lorcan Coyle. This project attempts to display the locations of individuals in an unobtrusive display from sensed real-time location information. This deals with the issue of combining real-time data with unobtrusive displays; real-time data is concerned with privacy while adding real-time data to situated displays is still relatively new. The Whereabouts Clock originally implemented by Microsoft Research is a situated display to show the whereabouts of family or friends. The Whereabouts Clock is used to find the locations of people such as family members and display it in a way that is unobtrusive, similar to the way a clock displays the time. While Microsoft Research use cell towers to track mobile phones, this project used computers with machine IDs and visible wireless devices to track users. The result of this project has been the development of a novel implementation of a Whereabouts Clock to determine and display a user's location. To test the value of the Whereabouts Clock, a user study was carried out over a course of 5 days. The user study found that the Whereabouts Clock was well received and would be a useful application for friends and family.
