In this paper we envision gaze-based interaction in and with large-scale outdoor spaces. We propose interaction using the gaze on real-world objects located and moving in urban environments, such as buildings or cars. A novel classification scheme is introduced which describes gaze-based interaction based on whether the user and the object(s) interacted with are stationary or moving. The classification scheme can be used for exploring the design space of mobile gaze-based interaction. We discuss the challenges specific for the dimensions of the classification scheme, focussing on the recognition of the object of regard, as well as on interaction design.
