InfoRadar: demonstrating how context helps mobile people interact

InfoRadar is a personal, context-aware mobile device. It enables people to share opinions and discuss topics related to places. In addition to messaging, InfoRadar supports voting on user-defined subjects. The UI is based on a radar representation providing an isomorphic representation of the digital content with the physical world. The radar UI can be used to explore the current location by zooming in, or remote locations by zooming out. The radar also shows traces of user movement, useful when interpreting activity taking place in remote locations. When creating content the user defines <i>when</i> and <i>where</i> it is accessible to others, enbling the expression of the context within which the content is relevant. These features and their use are elaborated using two scenarios inspired by observations from a field trial.
