The development of “smart stadia”, i.e. the use of “smart technologies” in the way sports stadia are designed and managed, promises to enhance the experience of attending a live match through innovative and improved services for the audience, as well as for the players, vendors and other stadium stakeholders. These developments offer us a timely opportunity to reflect on the ethical implications of the use of smart technologies and the emerging Internet of Things. The IoT has the potential to radically (...) transform society and is representative of the ways that novel technologies will alter human life. We use Dublin’s Croke Park stadium smart project as a case study for examining the development of smart stadia. (shrink)
