ROCKIT is a strategic roadmapping action in the area of multimodal conversational interaction technologies funded as a support action by the EU during 2014 and 2015. We envisage a future in which human-human, human-machine, and human-environment communication are not hampered by differences in language capability, accessibility, or knowledge of the technology, and where security and privacy are built in. These future conversational interaction technologies will enable interaction, collaboration, creativity, and information access within a vast, dynamic, heterogeneous, and partly ephemeral information space. ROCKIT is developing a roadmap to achieve this vision, linking research and innovation activities, and connecting a broad range of stakeholders. In this paper we present the ROCKIT roadmapping process, together with five target scenarios, which we believe can form a basis for discussion and engagement at the ICMI workshop which can further progress the community roadmap.
