In this paper we summarize the findings from a project developing smart urban objects to help elderly people participate in urban life. We present four key challenges that have been identified designing such objects, and present first ideas for how to address these challenges. The four key challenges are adaptability (and data privacy), multi-user usage, walk-up-and-use and joy of use.enCC BY 4.0 Attribution 4.0 InternationalHCIchallengessmart urban objectsoutdoorevaluationadaptationmulti-userwalk-up-and-usejoy of useUrbanLife+Text/Report10.18726/2021_12194-0282
