A new embodied digital rhetoric emerges when using nonfiction narratives built in fully immersive virtual reality systems that take advantage of the plasticity of our sensations of presence. The feeling of “being-in-the-world” as described by phenomenologists, including philosophy of mind, film, and virtual reality theorists, is part of the adaptability that humans show in their relationship to technological tools. Andy Clark's “soft selves” and our “plastic presence” merge as the high resolution graphics of the latest virtual reality goggles and robust audio captured at real events tricks our minds into having an embodied connection with the stories portrayed in these new spaces. By putting people into news or documentary pieces on scene as themselves, opportunities for persuasive and effective rhetoric arise. This chapter cites theory, psychology and virtual reality research as well as the author's specific case studies to detail the potential for this new embodied digital rhetoric that allows us to pass through the screen and become present as witnesses to a nonfiction story.

In the present paper, we discuss the design of a projection system with curved display and its enhancement by variably adjusting the curvature. We demonstrate that the focal surface curvature varies significantly with a change of the object position and that it can easily be computed with the Seidel aberration theory. Using this analytically derived curvature value as the starting point, we optimise a refocusable projection system with 90 ° field of view and F / # = 6.2 . It is demonstrated that such a system can provide stable image quality and illumination when refocusing from infinity to 1.5 m. The gain in spatial resolution is as high as 1.54 times with respect to a flat focal surface. Furthermore, we prove that a silicon die can be curved to the required shape with a safety factor of 4.3 in terms of the mechanical stress. Finally, it is shown that the developed system can be used in a virtual reality headset providing high resolution, low distortion and a flexible focusing mode.
