TalkingBadge is a Bluetooth platform for indoor location-based audio messaging, supporting zone-specific information retrieval and one-way text-to-speech paging via smartphones or a TalkingBadge piece of hardware that the user might carry with them. When people walk through a zone covering up to 50 meters, they can listen to short audio messages sent to them. The platform provides zone-based tracking in a low-cost fashion, which makes large-scale indoor deployment feasible for a range of locations, including airports, shopping malls, and hospitals. The platform design also addresses location-based services' privacy issues by using episodic rather than continuous tracking through the defined zones.
