Mobile Context-Aware Support for Public Transportation Users

We present a fully functional location-aware application prototype named Relevant Service Suggestion System, which runs on an off-the-shelf Nokia 6210 Navigator. The system allows the user to point and probe to find the services needed, using the awareness of the user’s location and the measured compass bearing, in addition to a distance range chosen by a physical gesture.

The main application tested in this paper is a system to support public transport users in Copenhagen. Users can point at any bus-stop or train station and be given timetables, next departure times, and buy a ticket via SMS direct to their phone. The requirements for text entry are minimal, due to the use of location, bearing and pose sensing.
