STAU is an interactive keychain that follows you everywhere, so simple that it won’t disturb you when driving or working, that would inform, alert & entertain you while prevent you from being stuck in traffic jam.
STAU takes traffic data of your daily route (ex. Google) and keeps only the essential information displaying colored dots around your daily steps. Your position is constantly updated by a self-moving disc emphasizing upcoming events and letting your friends or colleagues know of your progress. By dragging your position disc, the keychain indicates upcoming events: by pressing it, you can signal special issues (ex. car crash) to other drivers using the service. With only one click, it informs people of your delay by sending pre-written SMS or notifications or even voice messages. Thanks to your collected data & live traffic updates, the system can guess the best departure time or warn against premature departures and indicates when it’s the best time to leave! STAU – stressless auxiliary – won’t let you alone, stressed, in a traffic jam.
