Safe & sound: a wireless leash

Safe & Sound uses location-aware mobile phones to create a "virtual leash"; a secure zone beyond which a child may not travel. If the child leaves this zone, both child and parent receive audible alerts, and the parent can communicate with the child by voice over the phone. The peer-to-peer transmission of location, and the accepted role of responsibility by care-givers, reduce the privacy concerns which often arise with location-aware systems.
