This study explores how slideshow presentations shape the social organization of participatory democracy meetings. Prior research on slideshow presentations claims that the presentation format inhibits interaction between presenter and audience. This implies that the use of the technology hinders participation and dialogue. In contrast with prior research, the present Conversation Analytic study is based on video-recordings of meetings where slideshow presentations are used. The analysis focusses on when, how, and for what actions members of the audience self-select to take the turn during presentations. The empirical findings validate the idea that the slideshow format indeed constrains participation. However, the projectability inherent in the slideshow format, coupled with the presenter’s manipulation of material objects, also affords opportunities for audience participation. The presenter’s action can thus project impending transition-relevance places and provides audience members with opportunities to take the turn “in-between” the slides. Slide changes constitute a discernable locus for turn transition, providing a space where audience members can contest the presenters’ perspective and, at least momentarily, turn the monologue into dialogue. These findings contribute to a more nuanced understanding of how turn projection allows members to capitalize on possible points of turn completion in multimodal environments.
