“…Among them, the use of half-mirror film is one of the most realistic ways to produce a seamless image of synthetic imagery and physical objects in the space behind it. According to such characteristic, the technique has been widely used in various fields such as performances (Gingrich et al, 2013, Steinmeyer, 1999, marketing, showcases (Bimber and Raskar, 2005) and telepresence (Ogi et al, 2001). Also, it has recently been personalized and used in desktop workspaces where direct user input is required (Hachet et al, 2011;Hilliges et al, 2012).…”

“…Only the audience can see the digital information. Therefore, up to now, presenters need to thoroughly acquaint the digital information in advance in live presentations, performances and many other systems that have used a similar halfmirror system (Gingrich et al, 2013). However, there are limits to the abilities of the presenters to fully understand the forms and the positions of all the digital information beforehand.…”

While visualization alone can play a meaningful role, visualized images today often fail to invoke active engagement from the audience. In numerous cases, a human presenter's interactive involvement can drastically enhance the engagement with visualization. In this paper, we propose and further 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 referring 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 presentation 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 visualization. In terms of the presenter, five out of six participants chose HoloBox as their preferred presentation 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.

“…It enables viewers to see virtual images that appear to coexist in the same space as the real world. Starting with the hologram performance, Peppers Ghost (1869) [25], it has been expanding its application into telepresence [10], presentation, medical training [7], and desktop workspace for a long time. Recent research has shown that it has ability to enable viewers to rapidly mix real and virtual associated information and create the 3D illusion that viewers have visual integration naturally [11,15].…”

While the 3D graphics technique has found its place for the scientific visualization, especially for medical and biological applications, it has long been speculated that the 3D may not be so much effective as far as the conventional information visualization is concerned. We agree upon this view that the naive extension of the 2D visual forms to 3D is not a way to go. Instead, the computergenerated 3D virtual world will serve best when the virtual world is seamlessly integrated with the real 3D space. For an example, a physical automobile model surrounded with various kinds of virtual visual forms such as texts, images, sounds and 3D models will offer the user (or the audience) another level of appreciation and experience on the subject being presented. In this paper, we present our on-going developmental efforts toward the above framework which calls for the tight integration of the 3D visual forms and the 3D real space. The Spatial AR Hologram (SPAROGRAM) is capable of manifesting augmented three-dimensional information by making full use of the real 3D space that encompasses the surroundings of the real object comprehensively and simultaneously. To accomplish this, a multiple layer of stereoscopic images was implemented. Stereoscopic images enable spatial visualization using the physical and virtual third dimension. Furthermore, ensuring the continuity of the spatial experience, we made the use of spatial exploration with user interaction in real-time. We describe the whole process of system design and prototyping. Our initial investigation suggests that the newly conceived holographic display produce not only continuous 3D space perception, but also the better spatial awareness and realism. Furthermore, it is a promising way to present information in three-dimensional display and help the users understand information effectively and efficiently.
