Information radiators: using large screens and small devices to support awareness in urban space

Information radiators are ubiquitous stationary installations that radiate information that is likely to improve awareness of passers-by in semi-public environments like organization floors. In this paper, we present the idea of using several kinds of information radiators for enhancing urban participation of seniors - by providing awareness for supporting the planning and execution of activities in public environments. We motivate the idea and discuss interaction design as well as HCI challenges to be addressed in future work.1
