Shoutspace (one of the research project at our lab) now allows user to put location-based annotations in Geneva with mobile phones! Thanks to fab's hack!Basically, this program enables users to leave messages to other users on the map (our campus in Lausanne + Geneva). The message is then dispayed on the map at a desired location. Multiple threads are displayed graphically with connections among the messages: Now let's spread it and study how people use this application?
