“…Many embodiments of XR were originally built upon an early spatial computer called the SWIM (Sequential Wave Imprinting Machine) invented in the 1970s [18][19][20][21]. See Fig 2 . SWIM allowed for accurate alignment between the real and virtual worlds with delays much less than 1 microsecond (i.e.…”

UNSTRUCTURED This paper provides an overview of Mersivity, also known as Vironmentalism or XRSC (eXtended Reality Spatial Computing) with applications in health, well-being, and accessibility. There is a growing interest in technologies that are ’mersive (immersive, submersive, or supermersive), i.e. technologies that encapsulate or enclose or surround us. Examples include “wearables”, immersive VR (Virtual Reality), and electric vehicles such as self-driving cars, vessels, and personal aircraft (ABC = Aircraft, Boats, Cars). It is widely agreed that there is a risk or danger of asymmetry of immersive technologies that can separate us, harmfully, from our surroundings. In order to support human health, well-being, and accessibility, it is essential that we can ’merse any of these technologies that ’merse us. If one can’t go for a hike in the forest or along the beach (and maybe go for a swim as well) with the technologies that claim to help us, then those technologies are actually harming us. Thus an important element of Mersivity is a connection to the physical world = the world of “atoms” = nature = the environment = sustainability = our surroundings. Mersivity therefore is at the nexus of the physical (nature/sustainability/environment), virtual, and social worlds. In this paper we provide a historical perspective on XR+SC, from the early spatial computers of the 1970s, the introduction of XR=eXtended Reality in 1991, and leading up to the latest trends such as the “Freehicle” = vehicle of freedom for those with disabilities. See Fig 1.

“…The typical implementation of hardware-based ayinography utilizes the Sequential Wave Imprinting Machine (SWIM) technique to overlay the visual field onto the desired spatial plane. The SWIM uses multi-mediated reality to visualize invisible physical phenomenology, and thus it can be used for scientific measurement and analysis [7,10,22,23,26,28]. Typically, the SWIM uses a linear array of light sources connected to and receiving signals from a computing device.…”

Using a wearable electroencephalogram (EEG) device, this paper introduces a novel method of quantifying and understanding the visual acuity of the human eye with the steady-state visually evoked potential (SSVEP) technique. This method gives users easy access to self-track and to monitor their eye health. The study focuses on how varying the SSVEP stimulus frequency and duration affect the overall representation of a person's visual perception. The study proposes two methods for this visual representation. The first method is a hardware system that utilizes long-exposure photography to augment reality and collocate the visual map onto the plane of interest. The second is a software implementation that captures the visual field at a set distance. A three-dimensional mapping is created by gathering software-defined visual maps at various set distances. Preliminary results show that these methods can gain some insight into the user's central vision, peripheral vision, and depth perception.
