EcoChallenge

Abstract

Careful use of the limited remaining fossil energy resources is important for both ecological and economical reasons. In addition to technical improvements, fuel consumption of a vehicle is influenced significantly by the driving behavior. Currently, only few in-car user interfaces are trying to promote a more fuel-efficient driving behavior. We propose EcoChallenge, a community- and location-based in-car persuasive game with the goal to motivate and support a behavioral change towards a fuel-saving driving style. We implemented and integrated EcoChallenge in an experimental vehicle and evaluated it in a field study. The results regarding acceleration, deceleration, breaking and coasting show the effectiveness of our approach. In addition, users confirmed a very positive experience with our system.
