Passengers pay attention to the landscape as they move through the environment. We suggest a new type of applications, which adds to that experience. It consider their motion and velocity, which make the time available for interaction with individual geographical objects very limited, at the same time as they cannot control it. Applications, in this case a game, could utilize audio and gesture interfaces, as well as digital maps to provide for experiences that are sequentially mapped onto the landscape. An initial user feed back trial made visible interactional and experiential challenges in passengering.
