WEB VR FOR REAL: Gadgets that can take advantage of Web VR include the still-in-beta (via Facebook) and (pictured here).
Get ready to take the stage with Paul McCartney. If that’s not your thing, you can test-drive the latest SUV before it's available in showrooms or experience a movie as though you're in the scene. That's been (VR) for years, although stepping into an immersive virtual world has always required expensive stereoscopic head-mounted displays and other specialized equipment.A new, more accessible form of virtual reality delivered via the Web promises to let people experience digital worlds in 3-D using head-mounted displays connected to a variety of browser-enabled devices. Web VR is expected to offer the ability to move you from one immersive experience to another with a click of the mouse, touch of the screen or nod of the head. Web VR will let software developers port their virtual worlds to the Web, making them available for most VR hardware.Google and Mozilla are setting these wheels in motion within the next month or so when they deliver updated Chrome and Firefox browsers that support Web VR. earlier this year and the release of relatively inexpensive headsets from and Google provide further evidence that Web VR could be ready for wider use.VR for the massesvirtual reality modeling language, or VRML, aimed to allow the creation of virtual worlds—such as —linked together via the Web. But VRML could only be rendered using heavy-duty graphics workstations more likely found in a computer science lab or a data center than in one’s home. Although work on VRML , this first attempt was way ahead of the hardware.The availability of content will largely define Web VR’s success. Businesses have already begun buying into the concept of immersive advertising, thanks in large part to Facebook’s investment in Oculus. Beer brewery Dos Equis created a that places you at a fancy party with “.” To promote its new Volvo created , a virtual test drive and look at the car. Meanwhile the Sundance Film Festival's 2015 program, which showcases nontraditional and multimedia storytelling, will offer nine virtual reality works employing a variety of technologies. And Jaunt's virtual lets you walk around McCartney's piano, peering over his shoulder or looking into his eyes as he sings "Live and Let Die."All of these projects are app-based: Just like a smartphone app, you have to find them and download them individually to your computer or phone—and most of them will run on only one kind of headset. Available gadgets include the still-in-beta (targeted more at programmers than the average user) and . Google's DIY is an odd entry; the company offers directions to help you make a cardboard headset with lenses that you put over a smartphone to see VR content.Look for headsets to become more common as prices fall. "As we continue to see economies of scale, virtual reality gets smaller, faster and cheaper," says , lead experience designer on the Mozilla project.Immersive education and researchRyerson University, is developing , a digital tour of the human circulatory system using the Oculus Rift platform. Maldonado, the project’s leader, says he sees huge potential for Web distribution of this and other VR experiences.Online accessibility could also make Web VR appealing to psychology researchers, according to , director of the at the University of California, Santa Barbara. He regularly uses virtual environments to perform experiments because they eliminate the inescapable variations of interpersonal interactions. "With virtual reality you can create an experiment that runs the same for every subject," he says. But there's still the problem of recruiting a wide sample of subjects. "We don't often use representative samples—we know a lot about sophomores in college." If VR gear becomes cheap and widely accessible, experimenters could recruit more diverse sample groups using IP addresses, he adds.Virtual reality, actual softwareMozVR.com, a simple directory of virtual reality Web sites.Browser support is a work in progress. Brandon Jones, an engineer on Google's Chrome browser team, is working to add Web VR interfaces to Chrome, coordinating with Mozilla to make sure that VR content will run consistently in both browsers. "If only one browser supports this or different browsers support it in divergent ways, it won't be as compelling," he says. When contacted, Microsoft would not say whether it plans to enable Web VR in its Internet Explorer browser.New authoring tools in Chrome and Firefox should make it easier for Web developers to enable Web VR on their sites for those browsers. , an open-source project led by VRML pioneer , will let you use HTML-like tags and cascading style sheets, the basic tools of Web design, to create virtual worlds. And Unity, a popular 2-D and 3-D game-authoring tool, will support Web VR in an upcoming release. "We really believe that the Web could be the killer platform for virtual reality," Mozilla’s Carpenter says. "It is open, wild and creative."
