Cup of Coffee is an augmented reality game that provides a playful tone to the moments we spend driving our vehicles. The score system aims to reward drivers who drive according to the eco-driver concept. The App simulates the existence of a coffee cup in the console of the vehicle. The goal is not to spill coffee. Only braking events (deceleration) are considered in the rules of the game. The rule is simple: - Sudden decelerations represent events in which coffee is spilled, reducing the amount of coffee cups. - Soft decelerations conserve coffee, increasing the scoring; one cup of coffee is incremented every 100 points, limited to 3 cups. There are three levels of difficulty - One sip >> cutting deceleration: 10 km / h2 - Half cup >> cutting deceleration: 7 km / h2 - Full >> cutting deceleration: 5 km / h2 Score events in the "full" difficulty result in higher scores. On difficulty "one sip" the events result in lower scores. Decelerations are calculated in 1 second cycles.
