Design guidelines for micro information radiators to increase seniors' safety in urban space

Senior citizens face challenges during activities in urban space. To help and motivate them pursuing outside activities, we propose a network of (micro and macro) information radiators to increase their feeling of safety. In this paper we first collect guidelines and relevant aspects for the design of micro information radiators. Then we summarize our own experiences from a project designing smart urban objects - particularly giving an overview of design guidelines for input and output interaction of micro information radiators.
