One solution is offered by ridesharing concepts, realized with ICT supported mobile interaction systems. Current systems already address issues of comfort or efficiency and thus refer to mobility widely in functional terms of transport, moving people from one place to another. However, ridesharing is in its basic conception an interactive cooperation between at least two persons negotiating a shared ride. We argue in this paper for the necessary of a praxis-based perspective on ridesharing in order to explore the interactive mechanisms people refer to in ridesharing situations. We will show that a phenomenological inquiry provides added value in understanding practical challenges in ridesharing contexts, and identifying methods used to address practical challenges that can provide new starting points for design.enridesharingethnographyolder adultsmobilityText/Conference Paper2196-6826
