Does the sales success of the Oculus Quest 2 spell doom for tethered VR hardware and software? (Photo by Remy Gieling on Unsplash)

Cix Liv, a VR developer who has a bit of a reputation as a gadfly in the virtual reality industry, made the following bold claim on Twitter yesterday:

Sorry to my VR friends.

I declare PCVR dead.

Prove me wrong.

PCVR is the umbrella term used to refer to tethered VR headsets, which require a high-end desktop computer with a powerful graphics card to run. Examples of PCVR headsets are the Oculus Rift, the HTC Vive, and my beloved Valve Index. Right now, the standalone Oculus Quest 2 is selling like hotcakes, and Facebook has in fact stopped selling the Oculus Rift headset:

It was only a matter of time, really. Facebook announced in April of this year that it would not be sending more Rift S units to retailers—once they sold out, that was it for the Rift S.

“Rift S is still available for sale currently in some channels around the world, but as we announced last year, we plan to stop selling Rift S in 2021,” Facebook told UploadVR at the time. “Generally speaking, as channels sell out of stock, they won’t be replenished.”

So, while you can probably still get your hands on an Rift via resellers (you can still find units on Amazon, for example), its days are clearly numbered.

Is PCVR indeed dead, as Cix asserts? His tweet raised a lot of comments, among them Kent Bye, a thoughtful VR commentator and podcaster of the Voices of VR podcast:

Kent Bye: There’s still lots of things at the frontiers of digital culture still in PCVR< like film festivals (Sundance, Tribeca, Venice and SXSW) happening in the Museum of Other Realities, full-body tracking, LBE [location-based events], live theater in VRChat and NeosVR. It’s an open platform that’ll never really die.

Cix Liv: “Die” is an extreme claim that is lacking nuance. The more expanded nuance would address the specific use cases where it will never die: mocap [motion capture], LBE, emboded docial [platforms] like VRChat. For broad consumer uses, it’s dead [in my opinion).

Kent Bye: I disagree. New communications mediums never fully replace previous mediums. We still have radio, TV, PCs, phones. PCs are ‘open platforms”. Mobile has thermal/power tradeoffs and people will ALWAYS want premium experiences like Half-Life: Alyx, Also, Steam Deck is an open PC.

Thrillseeker actually dropped a 15-minute YouTube video on this very topic today:

The video is engaging and raises lots of good points, but Thrillseeker eventually declares himself for the PCVR-is-not-dead camp, noting that the Oculus Quest 2 can also be used as a PCVR headset. He predicts that PCVR will never die, as Kent did.

Cix Liv eventually got so much blowback that he tweeted:

Please god tell everyone else that in the thread who is lighting me up for saying this.

I am not hating on PC VR because it’s trendy, the numbers so low Devs can’t even make a living now.

The reasons can be debated, but it’s the reality.

Cix argues that the numbers of sales of PCVR hardware and software are now so much lower than standalone VR, that it’s not worth the risk to develop for PCVR. For example, Oculus just announced that Lone Echo 2 would be the last PCVR exclusive that they would be shipping. Steam statistics show that PCVR usage is down. There’s haven’t been any really big PCVR releases in a while, with really nothing to match the hype of Half-Life: Alyx. And PCVR-only social VR platforms have struggled lately, either pivoting to new markets (e.g. Sansar, to live events) or shutting down completely (e.g. the old High Fidelity platform).

So, what do you think? Is PCVR doomed, or it just having a pause? Are standalone VR headsets going to kill tethered VR headsets? Please feel free to leave a comment on this blogpost, or join in the never-ending, freewheeling discussions and debates taking place among the 500+ users on the RyanSchultz.com Discord server.

Using Social VR to Teach an Emerging Technologies Class at UNC Chapel Hill

Steven King is an associate professor of multimedia journalism and emerging technologies at the University of North Carolina, Chapel Hill, holding a joint appointment with the UNC Hussman School of Journalism and Media and the Kenan-Flagler Business School. In his work, King combines computer science concepts, human-centered design and storytelling to create new ways to present information through emerging technologies, such as virtual and augmented reality, artificial intelligence and other interactive media forms, such as interactive data-driven graphics.

When the university was impacted by the COVID-19 pandemic last year, Steven used both Mozilla Hubs and AltspaceVR to create a virtual classroom for his students:

If you ask a UNC student what their remote classroom experience has consisted of, they will likely tell you about video lectures through Zoom. But for students in Steven King’s class, they are experiencing remote learning differently — through virtual reality.

“I’m always trying to figure out a better way to teach and communicate,” King, a professor at the Hussman School of Journalism and Media, said. “I know virtual reality is an immersive experience.”

King built a virtual 3D version of his classroom, which allows his students to walk around in the classroom and break out into groups. 

He said he has tested out a lot of different platforms for hosting 3D classrooms. The first experience, he said, was through Mozilla Hubs. But King said his class will likely stick to AltspaceVR because of how pleased the students have been with it.

The Raleigh News & Observer reported:

“When you’re faced with a crisis, these are times to step up and figure things up and make new discoveries,” King said. “We don’t need to limit ourselves to the tools we have. We need to develop new tools to move us forward.”

King sent Oculus Go Virtual Reality headsets to his 28 students to use at home. King and the students built their own avatars, and they are all attending class together in a virtual world as robots, panda bears, ducks and other characters. King chose the superhero Ironman as his avatar.

The emerging technologies class was tailor-made for this type of experiment, King said. Students had become familiar with the technology throughout the semester while learning about artificial intelligence and augmented reality.

Steven wrote about his experience developing and delivering the course in a four-part series of Medium posts (here’s a link to part one). He described how he acclimated his students to AltspaceVR:

To help the students prepare for class. I gave the students an assignment to be completed before the first class hosted in AltspaceVR. I asked every student to signup for an account, go through the tutorial in their home space, and to go to the InfoZone, which is a tutorial in the form of a social fair about going to events. The final step of the assignment was to send me a friend request. I also recorded a video on how to enter the room/event…

This assignment was critical to the success of the next class. I needed the students to work through any technical issues on their own and to feel confident in another social VR environment. Once I got a friend request, I added them to the group so they could see the private event…

Most students arrived early and were ready to go. I let them spend several minutes interacting and exploring the space. There was lots of personal chatting, like I would see before an in-person class, which has been absent in my Zoom class.

The pandemic provided a golden opportunity which professors like Steven used to good advantage to provide their students with an introduction to social VR used for educational purposes. You can find out more about Steven and his work via his personal website.

The University of Michigan’s XR Initiative and the Extended Reality Nuclear Reactor Laboratory Project

The University of Michigan‘s Center for Academic Innovation founded an XR Initiative in September 2019, to work with all the U of M’s schools and colleges to fund new projects and provide consultation on the use of VR/AR/MR technology to support teaching and research.

The State of XR and Immersive Learning Outlook Report 2021 (available to download here), recently published by the Immersive Learning Research Network, describes one such project:

At the University of Michigan, the Center for Academic Innovation seeded six new XR projects in spring 2020 as part of an ongoing effort to fully embrace immersive education. One upcoming project explores the challenges of working within nuclear reactors. The school’s Ford Nuclear Reactor in Michigan permanently shut down in 2003 and was decommissioned in the years following, leaving the top-ranked university program without a research reactor. This XR project will develop an Extended Reality Nuclear Reactor Laboratory simulation where students can virtually walk around the reactor, look into the core, and interact with the control panel.

As Brendan Kochunas, project manager and assistant professor in the Department of Nuclear Engineering and Radiological Sciences described it (2020): “In reality, one does not simply walk up next to an operating nuclear reactor core, but in virtual reality one can. We can also overlay simulation results on the virtualized physical systems allowing students to experience neutron fields or temperature fields visually, where in reality this is not possible.”

The faculty and staff newspaper UM Record provides some more background:

The College of Engineering is home to the No. 1 nuclear engineering program in the country. For several decades up to the early 2000s, the program included training at a physical nuclear reactor. The Ford Nuclear Reactor, originally established as a WWII memorial under the Michigan Memorial Phoenix Project, permanently shut down in 2003.

It was decommissioned over the next four years, leaving U-M as one of the only programs without a research reactor, both in the Top 5-ranked university programs and the Big 10, said Brendan Kochunas, project manager and assistant professor in the Department of Nuclear Engineering and Radiological Sciences.

The Extended Reality Nuclear Reactor Laboratory simulation would allow some retired courses that used the Ford Nuclear Reactor to be taught again to upper level undergraduates and graduate students.

“I hope to gain experience and insight into how to apply XR technologies in a practical way to enhance education and research in the field of nuclear engineering,” Kochunas said. “I think XR has such potential for this area of science, or really any area of science where the reality is you have a physical system that is expensive or potentially hazardous.”

An article by Sara Norman on the University of Michigan College of Engineering website describes the project in more technical detail:

Over the past year, a project team within the U-M Department of Nuclear Engineering & Radiological Sciences (NERS) has been working with the XR Initiative in the Center for Academic Innovation to develop the Extended Reality Nuclear Reactor Laboratory—a virtual representation of the now decommissioned Ford Nuclear Reactor (FNR) that was once the center of the Michigan Memorial Phoenix Project (MMPP).

Yuxuan Liu, a member of the project team and an Assistant Research Scientist within NERS, has received a Simulation Grant from the Office of the Associate Dean for Undergraduate Education (ADUE) to develop a simulation of heat transfer in the original FNR. Understanding the heat transfer in a nuclear power reactor is essential to its operation and maintaining safety, making this virtual experience an important lesson of the NERS Extended Reality Nuclear Reactor Laboratory course. The other member of the project team is NERS Prof. Brendan Kochunas.

The XR Initiative is a good example of a university-wide program to make XR technology more accessible on campus and encourage its use in higher education, working with university faculty to actively look for new ideas and opportunities to support immersive learning projects, and enhance students’ learning experience. I look forward to seeing other such initiatives spring up on university campuses!
