Ubiquitous computing systems raise unprecedented challenges to how we currently elicit, secure and sustain user consent. Consent is the interactional process by which a user agrees to the terms of engagement with a system, and it represents the principle mechanism by which we protect our privacy online. However, whereas traditional online interactions are explicit, offering a series of moments at which one might inform and engage the user, the growing 'era of ubiquity' has decoupled users from devices, presenting no clear moment for consent to occur. Whilst there have been efforts to raise issues of consent within HCI and cognate disciplines, these remain disparate. The aim of this workshop is to bring together a solution-oriented community with a specific focus on consent issues within interactive environments. It will create a transnational, multidisciplinary platform for discussion and offer opportunities for collaboration, support and the development of a new research agenda.
