For the past year, I’ve been thinking a lot about virtual reality and its potential applications for historians. Can we use virtual reality to better understand the past? Can the experience of virtual reality alter historical thinking? Can we now build time machines, teleporters, and holodecks using virtual reality?
These questions may be overly optimistic or idealistic. I may look back on this article a year from now and shake my head and chuckle at my naive enthusiasm for this technology. But for now, VR has got me thinking about the future of history.
VR stands apart from other multimedia technologies primarily because of its ability to generate a sense of presence. Thomas B. Sheridan describes this as a “sense of being physically present with visual, auditory, or force displays generated by a computer.” He proposed three measurable physical variables to determine what he called “telepresence” and “virtual presence”: (1) extent of sensory information; (2) control of relation of sensors to environment; and (3) ability to modify physical environment. Does VR have the potential to generate a sense of the presence of the past?[i]
John Bonnett’s concluding remarks in his 2003 article on the 3D Virtual Buildings Project in Journal of the Association for History and Computing suggest that I’m not alone in my enthusiasm. He wrote, “3D environments are instruments, and if properly exploited they stand to provide historians with substantial gains in their capacity to teach, represent and analyze the past.” Remarkably, Bonnett’s outlook on the future of 3D environments predicted some of the most recent developments in virtual reality and augmented reality technologies:
In this vision of computing, users in near future will wear computers with the computational power of today’s desktops, and the size of today’s personal digital assistants. These computers, in turn, will be connected to wireless networks to access and post information, and to head mounted displays the size of glasses to display information. I mention this newly emerging field because it is already making a contribution to the way we represent the past, and the way we tell stories. In principle, it should be possible in the next 10 to 20 years to produce something akin to the holodeck from Star Trek. We will not be able to interact with objects without the mediation of glasses or gloves. But we should be able to generate representations of ancient Rome or 19th century Paris, and project them onto football fields.fields.[ii]
Smartphones with stereoscopic viewers (Google Cardboard, Daydream View, Gear VR) and tethered VR/AR headsets like the HTC Vive, Oculus Rift, and Microsoft HoloLens have brought us closer to that holodeck-like experience. Immersing yourself in a 3D representation of nineteenth-century Paris is not a fantasy. It can be done now.
In this article, I’d like to show some examples of how VR can be used today to, in Bonnett’s words, “teach, represent and analyze the past.” Continue reading
