TU Graz Researcher Uses VR to Transform Learning

Johanna Pirker’s Maroon: A Virtual Physics Lab for Schools

At the Graz University of Technology, assistant professor Johanna Pirker is developing virtual reality environments designed to revolutionise how students learn subjects like physics and chemistry. Her project, Maroon, is a virtual physics laboratory that allows students to conduct experiments that would be too dangerous, expensive or impractical in a traditional classroom. Through a VR headset, users can explore and repeat experiments indefinitely—an advantage tied to stronger learning outcomes, particularly in science education.

Pirker, who studied at MIT and earned her doctorate jointly between Graz and the US, was recently named to the Forbes “30 under 30” Europe list in the Science category. Her research focuses on how video-game mechanics and VR immersion affect motivation, collaboration and information retention. The Maroon platform is currently in a testing phase, and while it has won awards—including “Best Visualised Experiment”—Pirker admits that a mass rollout in schools is far from guaranteed, given the cost and technical requirements of VR hardware.

Beyond physics, a chemistry variant is already in the works, and a version of the lab is being designed to adapt experiment settings individually for each learner. Pirker’s ultimate aim is to use the intense focus that VR can generate to counter the shortening attention spans common among younger generations. By immersing students in a distraction-free digital space where emotions are heightened, she argues, learning becomes deeper and more engaging.

Why Immersion Matters for Learning—and Where VR Goes Next

The Science of Immersion and Focus

Pirker’s core thesis rests on the concept of immersion—the feeling of truly being “inside” a virtual world. With a VR headset, external distractions vanish, and the user’s emotional response to digital content is amplified. For a generation accustomed to constant notifications and short-form media, that forced focus is a significant asset. Studies in cognitive psychology have long linked higher levels of immersion to improved recall and skill acquisition, and Pirker’s work translates those laboratory findings into a practical classroom tool. However, the current requirement for expensive PC-tethered headsets limits access; many schools cannot afford the equipment, and the physical space needed for safe movement during VR experiments remains a barrier.

VR Beyond Gaming: From Real Estate to Live Sports

While gaming still dominates the VR market—with devices like PlayStation VR, Oculus Rift and HTC Vive leading sales—the technology is rapidly spreading into non-tech sectors. The article identifies real estate as an early adopter, where virtual property tours are already offered to developers and prospective buyers. Corporate training, sales simulations and recruitment are also well established. The next major commercial push, according to experts cited, will come from entertainment: film producers are increasingly inviting Pirker to discuss how VR can offer viewers multiple perspectives and even let them influence storylines. Even more promising, chipmaker Intel views live sports broadcasts in VR as the “catalyst for the mass market,” having paid $170 million for VR firm Voke.

The Hardware Hurdle and IDC’s Billion-Dollar Forecast

Market data from the International Data Corporation (IDC) paints an optimistic picture: about 8 million VR headsets were sold in 2016, nearly double that in 2017, and sales are expected to climb to 76 million units by 2020. Total worldwide spending on augmented and virtual reality products and services is projected to jump from $11.4 billion in 2017 to roughly $215 billion by 2021, covering not just entertainment but also industry and education. Yet technical challenges remain: many users still suffer from motion sickness, and comfort is a work in progress. Facebook has already poured $250 million into VR development through Oculus, signaling that deep pockets will be needed to solve both hardware comfort and content gaps. Pirker herself is betting on mobile VR—headsets that work with a smartphone—to solve the cost and accessibility problem, creating simpler, cheaper devices that can reach a much wider audience, especially in education.

Next Steps for Education Leaders and VR Innovators

• For school administrators and education ministries: Pilot programmes with platforms like Maroon could provide evidence of learning gains. Budget planning should consider partnerships with researchers to obtain grants, offsetting the current high cost of PC-based VR kits.
• For edtech developers: Pirker’s mobile VR approach, which uses smartphones and low-cost build-it-yourself headsets, offers a template for scaling in low-income regions. Content must be designed for repeatable, self-directed use and to minimise motion sickness.
• For hardware makers and investors: IDC’s $215 billion forecast through 2021 depends on breakthroughs in education and industrial adoption, not just gaming. Companies that invest in smartphone-based VR platforms (e.g., Facebook’s continued R&D spend) could capture a large share of the non-gaming market, but must solve the motion sickness problem to sustain growth.
