This video - A Machine. Learning - adopts a ‘research through design’ approach to producing a design fiction prototype. By using a research through design approach that is grounded in the practical experience of creating a design fiction we contribute practical insights about the process of creating a design fiction for HCI. Reflecting on the production of the video we explore challenges and opportunities presented by the design fiction method when it is applied to near-future HCI scenarios. The video depicts the story of Manu and his new artificially intelligent portable device. In the paper we consider the video, using it as a means to contrast design fiction with other approaches to prototyping; we describe the story, content and style of the video; finally we reflect on the production of the video (writing, filming and editing processes) in order to offer practical insights to the HCI community, with regards to prototyping using design fiction and film.
