The evolution of VR spaces and experiences

Six years ago, Meta launched the first consumer version of its VR headset, the Oculus Rift CV1. I had my first experience of that new media interface at San Francisco's Game Developer Conference (GDC). Oculus technicians escorted me into a sound-proof dark room and outfited me with the headset attached to an overhead boom that would keep the wires out of my way as I experienced free motion simulated environments that were crafted in Epic's Unreal Engine world-building game architecture. (This is the same developer environment that was used to create The Mandalorian TV series.) The memory of that demonstration is strong to this day because it was such a new paradigm of media experience. As I moved in a simulated world, parallax depth of distant objects shifted differently relative to those objects near. Everything appeared a bit like a cartoon, more colorful than the real world. But the sense of my presence in that world was incredibly compelling and otherwise realistic.

Yesterday I went into a physical VR gym in Richmond, California with a dozen other people to try a simulated journey where we would physically walk on a virtual replica of the International Space Station. It was profound to reflect on how much the technology has advanced in the six years since my first simulated solitary spacewalk at the GDC. The hosts of the event walked us through a gradual orientation narrative like were were astronauts ascending the top of an Apollo era launch tower before we were set free to roam on the purely visual ISS along with brief video greetings from real astronauts, previously filmed, at the exact locations marked by green dots on the map to the right. When we approached the astronauts, glowing orbs showed camera positions that were filmed on the ISS previously. By standing right where the astronauts were in the filming we could see all the equipment and experience what it was like to live on the ISS for those astronauts.

In a recent interview with Wall Street Journal reporters, Philip Rosedale (the founder of Linden Labs) commented, "The appeal of VR is limited to those people who are comfortable putting on a blindfold and going into a space where other people may be present." Here I was, actually doing that in a crowd of people I had never met before. All I could see of those people was a ghostly image of their bodies and hand positions with their gold/blue/green heart beacon indicating their role as fellow VR astronauts, family members for those in a group, or the event staff who kept an eye out for anyone having hardware or disorientation issues with the VR environment. Aside from an overheating headset warning and a couple of times the spatial positioning lost sync with the walls of the spaceship, I didn't have any particular issues. It was very compelling!

Six years ago at GDC, I remember a clever retort a developer shared with me at the unveiling of the Rift CV1. While waiting in line at the demo booth, I asked what he thought about nascent VR technology. He said, “Oh, I think it will be like the xBox Kinekt. At first, nobody will have one and everyone will want one. Then, later, everyone will have one and nobody will want one!” Now, years later, we can look back in retrospect to see what happened. VR didn't reach a very broad market penetration yet because of rather high price of hardware. But when the pandemic shuttered the outside world to us temporarily, many of us took to virtual workrooms to meet, socialize and work. Meta was well positioned for this. Zoom conference calls felt like flashbacks to the Brady Bunch/Hollywood Squares grid of tic tac toe faces. Zoom felt oddly isolating in contrast to sharing spaces with people physically. Peering into people’s homes also seemed a little disturbing. Several engineers and product managers I frequently meet with suggested we switch to VR instead. One of them challenged me to give a lecture in VR. So I researched how Oxford University was doing VR lectures in EngageVR and conducted my own lecture on the history of haptic consumer technology in an EngageVR lecture room. It was challenging at the time getting around lecture slide navigation and simultaneously controlling my spatial experience of appearing as a lecturer in the classroom. But I succeeded in navigating the rough edges of the early platform limitations. (EngageVR has drastically improved since then, introducing customizable galleries and broader support of imported media assets.)

While the experience felt rough at first, I found it much more compelling than using shared slides and grid camera views of the Zoom conference call format. So my colleagues collaborated with me to create a bespoke conference room where we could import dozens of lecture resources, videos, pdfs and 3D images. In this conference room a large group could assemble and converse in a more human-like way than staring into a computer camera. While we gave up the laptop camera with its tag-team game of microphone hand-off, we took up using VR visors where we could see everybody at once, oriented around us in a circle. Participants could mill around the room and study different exhibits from previous discussions while others of us were engrossed in the topic of the day.

I know that people like us are rather atypical because we adopt technology long before the mainstream consumer. But the interesting thing is that years later, even with the pandemic isolation waning, we all still prefer to convene in our virtual conference spaces! It typically comes down to two choices of where we convene. If it’s a large group, we assemble in the lecture hall hosted on Spatial’s web servers. These are fast paced and scintillating group debates where we have to coordinate speakers by hand waving or following auditory cues of interjecting speakers. If it’s four people or less, we use EngageVR or VTime, which allow for a more intimate discussion. Those platforms have us use virtual avatars that, unlike Spatial, don’t resemble our physical bodies or faces. But the microphone handoff of the dialog is very easy to hear natural language auditory cues of speakers.

“Why does this simulated space feel more personal than the locked-gaze experience of a Zoom call?” I wondered. My thought is that people speak differently when they are being stared at (camera or otherwise) than when they have free moving gaze and a sense of personal space. Long ago I heard an interview with NPR radio show host, Terry Gross. She said that she never interviewed her guests on camera, as she preferred to listen closely only to their voice. Could this be the reason the virtual conference room feels more personal than the video conference?

During my years studying psychology, I remembered the idea of Neuro-Linguistic Programming in which author Richard Bandler lectured that the motion of eyes allows us to access and express different emotions that are tied to how we remember ideas and pictorial memories. In NLP’s therapeutic uses, a therapist can understand traumatic memories discussed in the process of therapy based on how people express with their eyes and bodies during memory recollection. Does freedom from camera-gaze permit better psychological freedom in the VR context perhaps?

In lectures and essays by early VR pioneers, I kept hearing references to people preferring the virtualized environment among those who identified as neurodivergent. In my early study of autism spectrum disorder, I had read that one theory if ASD is an over-reaction to sensory stimuli. Often people who have ASD may avoid eye contact due to the intensity of social interaction. In casual contexts this behavior can be interpreted as an expression of disinterest or dislike. Perhaps virtualized presence in VR can address this issue of overstimulation, allowing the participants to have a pared down environmental context. In an intentionally-fabricated space, everything there is present by design.

I still don’t think the trough of the hype cycle is upon us for VR. (Considering the perspective of my developer friend’s theory about the land of VR disenchantment.) First, VR is still too expensive for most people to experience a robust VR setup. The "Infinite" ISS exhibit costs considerably more than watching a IMAX movie, its nearest rival medium. Yet soon Samsung, ByteDance, Pimax and Xiaomi are coming to market with new VR headsets that will drive down the cost of access and give most of the general public a chance to try it. I'm curious to see when we will get to that point of "everybody having it and nobody wanting it." I still find myself preferring the the new media social interactions because they approximate proximity and real human behavior better than Zoom, even if they still have a layer of obvious artificiality. 

A funny thing is that I have a particular proclivity to preferring visits to space for my VR social sessions. After my GDC experience years ago I downloaded the BBC's Home VR app that simulates a semi-passive perspective of an astronaut conducting a space walk. This allowed me to relive my GDC experience, with a surprise twist involving space debris. Then I tried the Mission ISS walk-through VR app that gives users a simulated experience of floating around inside a realistic looking simulated ISS assembled from NASA photographs of the station. Then, when Meta announced its new Horizon Venues platform, I was able to go into a virtual IMAX theater with a gigantic half-dome theater rendered in front of hundreds of real-time avatars of people from around the world to watch 360 videos from taken from the ISS and produced for redistribution by Felix & Paul Studios. And finally this week I was able to visit the Phi Studios physical walk-through. What I like about this progression is that the experience became more and more social. Getting away from the feeling of the movie Gravity, of being isolated in space.

Yet, for the most social experience of all, my friends and I like to go to an artificial simulated space station hovering 250 miles above earth where we can sit and have idle conversations as a realistic-looking model of Earth spins beneath us. This is powered by a social app called Vtime. When I go here with my colleagues, we inevitably end up talking about the countries we're orbiting over and relating experiences that are outside of our day to day lives. Perhaps it takes that sense of being so far removed from the hum drum daily environment to let the mind wander to topics spanning the globe and outside the narrow confines of our daily concerns. In one such conversation, my friend Olivier and I got into a long discussion about the history and culture of Mauritius, his home country, over which we were then flying. Vtime's Space Station location only has 4 chairs for attendees to sit in at a time. So we use this for small group discussions only. If you ever get inspired to try VR with your friends, I recommend trying this venue for your team discussions. It's hard to say what is so compelling about this experience in contrast to gazing at people's eyes in a video conference. But even after the pandemic lockdown subsided and we could once again meet in person, I still find myself drawn back to this simulated environment. I believe when every one of us has access to this, we will come to prefer it for remote-meetings in lieu of the past decades' 2D panel plus camera.
