The increasing proliferation of smart objects in everyday life has changed how we interact with computers. Instead of concentrating computational capabilities and interaction into one device, everyday objects have naturally integrated parts of interactive features. Although this has led to many practical applications, the possibilities for explicit or implicit interaction with such objects are still limited in interaction spaces. We still often rely on smartphones as interactive hubs for controlling smart objects, hence not fulfilling the vision of truly smart objects. The workshop "Rethinking Smart Objects" invites practitioners and researchers from both academia and industry to discuss novel interaction paradigms and the integration and societal implications of using smart objects in interactive space. This workshop will include an action plan with leading questions, aiming to move the research field forward.
