In numerous cases, a human presenter’s interactive involve- ment can drastically enhance the engagement with visualization. In this paper, we propose and fur- ther develop a novel concept called augmented presentation, in which a human presenter occupies the same physical space as the visualization, thereby presenting and interacting with the visualized information seamlessly. We focus mainly on investigating the potential of the presenter by refer- ring to the interaction framework for visualization and the proposed presenter’s roles. Depending on the type of interaction and level of engagement, the presenter’s role may vary from a narrator to an augmenter who may be regarded as part of the visualization. Further developing the idea of augmented presentation, we designed and implemented a presentation system named HoloBox. Then, we conducted two user studies to investigate the possibilities of HoloBox as a new presenta- tion channel. The results suggest that our new form of augmented presentation has the potential to enhance the quality of presentations and enrich the audience experience with regard to visualiza- tion. In terms of the presenter, five out of six participants chose HoloBox as their preferred presen- tation method despite the extra effort required to make a presentation. We believe that our augmented presentation can support new forms of visualization and information delivery. RESEARCH HIGHLIGHTS • Presents and develops augmented presentation concept, in which the human presenter intervenes as a part of 3D visualization interactively and enhances the visualization delivery. • Designs elements of augmented presentation concept and implements it through a HoloBox system. • Conducts two user studies to investigate the feasibility of augmented presentation.

INTRODUCTION Visualization aids in presenting complex and abstract data using visual metaphors to help people better understand and gain insight into raw quantities. Rather than just showing a visualiza- tion, presenting visual content to people is more effective in fields such as education, entertainment and advertising. In many cases, visualization is transported by the human presenter. At this moment, the behavior of the presenter is as crucial as his or her message. The presenter’s involvement in visualization can pro- vide cognitive and learning benefits to the audience’s data per- ception. For example, the presenter’s facial expressions, gestures and verbal explanations may help the audience focus on relevant visual information and build a connection between multiple representations (Fiorella and Mayer, 2016; Krekhov et al., 2017).
