Google Calls It Quits With VR, But Cardboard Lives On

March 30, 2021 by Tom Nardi 16 Comments

Google giving up on one of their projects and leaving its established userbase twisting in the wind hardly counts as news anymore. In fact, it’s become something of a meme. The search giant is notorious for tossing out ideas just to see what sticks, and while that’s occasionally earned them some huge successes, it’s also lead to plenty of heartache for anyone unlucky enough to still be using one of the stragglers when the axe falls.

So when the search giant acknowledged in early March that they would no longer be selling their Cardboard virtual reality viewer, it wasn’t exactly a shock. The exceptionally low-cost VR googles, literally made from folded cardboard, were a massive hit when they were unveiled back in 2014. But despite Google’s best efforts to introduce premium Cardboard-compatible hardware with their Daydream View headset two years later, it failed to evolve into a profitable business.

Of course if you knew where to look, the writing had been on the wall for some time. While the Daydream hardware got a second revision in 2017, and Google even introduced a certification program to ensure phones would work properly with the $100 USD headset, the device was discontinued in 2019. On the software side, Android 7 “Nougat” got baked-in VR support in 2016, but it was quietly removed by the time Android 11 was released in the fall of 2020.

With Cardboard no longer available for purchase, Google has simply made official what was already abundantly clear: they are no longer interested in phone-based virtual reality. Under normal circumstances, anyone still using the service would be forced to give it up. Just ask those who were still active on Google+ or Allo before the plug was pulled.

But this time, things are a little different. Between Google’s decision to spin it off into an open source project and the legions of third party viewers on the market, Cardboard isn’t going down without a fight. The path ahead might be different from what Google originally envisioned, but the story certainly isn’t over.

Virtual Reality With A Dash Of Live Shakespeare

March 27, 2021 by Roger Cheng 5 Comments

Virtual reality headsets enforce an isolated experience, cutting us off from people nearby when we put one on our head. But in recent times, when we’re not suppose to have many people nearby anyway, a curious reversal happens: VR can give us a pandemic-safe social experience. Like going to our local community theater, which is an idea [Tender Claws] has been exploring with The Under Presents.

VR hype has drastically cooled, to put it mildly. While some believe the technology is dead and buried, others believe it is merely in a long tough climb out of the Trough of Disillusionment. It is a time for innovators to work without the limelight of unrealistic expectations. What they need is a platform for experiments, evaluate feedback, and iterate. A cycle hackers know well! The Under Presents is such a platform for its corner of VR evolution.

Most VR titles are videogames of one genre or another, so newcomers to the single-player experience may decide its otherworldly exploration feels like Myst. A multi-player option is hardly novel in this day and age, but the relatively scarcity of VR headsets means this world is never going to be as crowded as World of WarCraft. This is not a bug, it is a differentiating feature. Performers occasionally step into this world, changing the experience in ways no NPC ever could. A less crowded world makes these encounters more frequent, and more personal.

Pushing this idea further, there have been scheduled shows where a small audience is led by an actor through a story. As of this writing, a run of a show inspired by Shakespeare’s Tempest is nearing its end. The experience of watching an actor adjusting and reacting to an audience used to be exclusive to an intimate theater production. But with such venues closed, it is now brought to you by VR.

How will these explorations feature in the future of the technology? It’s far too early to say, but every show moves VR storytelling a little bit forward. We hope this group or another will find their way to success and prove the naysayers wrong. But it is also possible this will all go the way of phone VR. We are usually more focused on the technical evolution of VR here, but it’s nice to know people are exploring novel applications of the technology. For one can’t exist for long without the other.

All The Good VR Ideas Were Dreamt Up In The 60s

January 4, 2021 by Donald Papp 39 Comments

Virtual reality has seen enormous progress in the past few years. Given its recent surges in development, it may come as a bit of a surprise to learn that the ideas underpinning what we now call VR were laid way back in the 60s. Not all of the imagined possibilities have come to pass, but we’ve learned plenty about what is (and isn’t) important for a compelling VR experience, and gained insights as to what might happen next.

If virtual reality’s best ideas came from the 60s, what were they, and how did they turn out?

Interaction and Simulation

First, I want to briefly cover two important precursors to what we think of as VR: interaction and simulation. Prior to the 1960s, state of the art examples for both were the Link Trainer and Sensorama.

The Link Trainer was an early kind of flight simulator, and its goal was to deliver realistic instrumentation and force feedback on aircraft flight controls. This allowed a student to safely gain an understanding of different flying conditions, despite not actually experiencing them. The Link Trainer did not simulate any other part of the flying experience, but its success showed how feedback and interactivity — even if artificial and limited in nature — could allow a person to gain a “feel” for forces that were not actually present.

Sensorama was a specialized pod that played short films in stereoscopic 3D while synchronized to fans, odor emitters, a motorized chair, and stereo sound. It was a serious effort at engaging a user’s senses in a way intended to simulate an environment. But being a pre-recorded experience, it was passive in nature, with no interactive elements.

Combining interaction with simulation effectively had to wait until the 60s, when the digital revolution and computers provided the right tools.

The Ultimate Display

In 1965 Ivan Sutherland, a computer scientist, authored an essay entitled The Ultimate Display (PDF) in which he laid out ideas far beyond what was possible with the technology of the time. One might expect The Ultimate Display to be a long document. It is not. It is barely two pages, and most of the first page is musings on burgeoning interactive computer input methods of the 60s.

The second part is where it gets interesting, as Sutherland shares the future he sees for computer-controlled output devices and describes an ideal “kinesthetic display” that served as many senses as possible. Sutherland saw the potential for computers to simulate ideas and output not just visual information, but to produce meaningful sound and touch output as well, all while accepting and incorporating a user’s input in a self-modifying feedback loop. This was forward-thinking stuff; recall that when this document was written, computers weren’t even generating meaningful sounds of any real complexity, let alone visual displays capable of arbitrary content.

Tired Of The Cat-and-Mouse

November 7, 2020 by Elliot Williams 49 Comments

Facebook just announced their plans for the Oculus Quest 2 VR headset. You probably won’t be surprised, but they want more of your user data, and more control over how you use the hardware. To use the device at all, you’ll need a verified Facebook account. Worse, they’re restricting access to the wide world of community-developed applications by requiring a developer account to be able to “sideload” non-Facebook software onto the device. Guess who decides who gets to be a developer. Hint: it’s not the people developing software.

Our article suggests that this will be the beginning of a race to jailbreak the headset on the community’s part, and to get ahead of the hackers on Facebook’s. Like every new release of iOS gets a jailbreak within a week or two, and then Apple patches it up as fast as they can, are we going to see a continual game of hacker cat-and-mouse with Facebook?

I don’t care. And that’s not because I don’t care about open hardware or indie VR developers. Quite the opposite! But like that romance you used to have with the girl who was absolutely no good for you, the toxic relationship with a company that will not let you run other people’s games on their hardware is one that you’re better off without. Sure, you can try to fix it, or hack it. You can tell yourself that maybe Facebook will come around if you just give them one more chance. It’s going to hurt at first.

But in the end, there is going to be this eternal fight between the user and the company that wants to use them, and that’s just sad. I used to look forward to the odd game of cat and mouse, but nowadays the cats are just too well bankrolled to make it a fair fight. If you’re buying a Quest 2 today with the intent of hacking it, I’d suggest you spend your time with someone else. You’re signing up for a string of heartbreaks. Nip it in the bud. You deserve better. There are too many fish in the sea, right?

What are our options?

As Facebook Tightens Their Grip On VR, Jailbreaking Looks More Likely

November 3, 2020 by Donald Papp 57 Comments

The Quest 2 wireless VR headset by Oculus was recently released, and improves on the one-and-a-half year old Quest mainly in terms of computing power and screen resolution. But Oculus is owned by Facebook, a fact that Facebook is increasingly keen on making very clear. The emerging scene is one that looks familiar: a successful hardware device, and a manufacturer that wants to keep users in a walled garden while fully controlling how the device can be used. Oculus started out very differently, but the writing has been on the wall for a while. Rooting and jailbreaking the Quest 2 seems inevitable, but what will happen then?

Open Source VR Headset For $200

September 13, 2020 by Al Williams 19 Comments

We’ve seen homemade VR headsets before, but, often they are dependent on special software or are not really up to par with commercial products. Not so with Relativity, an open source project from [Max Coutte] and [Gabriel Combe]. [Max] says it best:

Relativty is not a consumer product. We made Relativty in my bedroom with a soldering iron and a 3D printer and we expect you to do the same: build it yourself.

Unlike some homebrew gear, Relativity has full Steam VR support. It also has experimental support for positional scaling that tracks your body based on video input.

Want To Support Hacker-friendly Hardware Design? Follow Valve’s Example

August 20, 2020 by Donald Papp 5 Comments

It’s been just over a year since Valve released Index, their flagship VR system, and it’s worth looking back at this GitHub repository as a fine example of how to provide supporting materials to a hacker-friendly hardware design. The image above shows off one of the hacker-friendly design elements: an empty space behind the visor, with a USB port off to the right, that exists for no reason other than to make it easier to mount and plug in whatever one might come up with. There’s more to it than that, however. If one wishes to provide supporting materials for a hardware design, one could certainly do worse than emulate Valve’s example.

The violet 3D model shows the area that modifications can occupy without getting in the way of any sensors.

The hardware repository contains not just CAD models of mod-friendly hardware pieces (both in high-resolution STEP models as well as STL files) but also 3D models of the sensor zones, so modders can ensure they avoid occluding any sensors with their creations. Examples are great, and one provided by Valve is the Booster; a hand controller add-on providing extra comfort for people with large hands or long thumbs. The model also doubles as a reference for designing attachments that will not interfere with any of the tracking or touch-sensitive surfaces of the controllers.

Being hacker-friendly doesn’t mean the hardware has no warranty, but it does mean that there is concrete guidance on what does or doesn’t risk voiding it. In the case of the Index hardware, the guidance is simple: “Anything that requires a T5 or smaller is not user serviceable.”

To us, the whole attitude of being hacker-friendly is exemplified by a statement about the headstrap, found about half-way down the page. The words “removing the headstrap is not recommended” are followed immediately by clear directions on how to do exactly that, demonstrating the kind of trust necessary to reduce barriers for add-ons and modifications. That is a great way to help foster experimentation, like this project for 1:1 mapping of physical elements to their VR counterparts, to make awesome spaceship cockpits.
