Tangible Interaction as a resource for Relational HCI.

In this paper, we propose to delineate the emerging field of Relational HCI coming from the domains of assistive technologies and community technologies. We briefly describe our work on the relational design of an interactive map for visually impaired people and then outline three principles which characterize this new HCI perspective. We conclude on the very potential of TUIs to develop this relational perspective of HCI.
