Maroon (2013-now) is a interactive physics laboratory and experiment environment implemented in Unity3D, designed for active learning in the classroom or at home. It visualizes and simulates various experiments with a focus on physics experiments. Since 2018 it is supported by the Austrian Ministry for Education and introduced for first tests in Austrian schools. 

  • 2017 GOLC Award for “Best Visualized Experiment”
  • 2018 Feature at Forbes Magazine (DE/AT)

Maroon support three main environments:

    • Maroon Web
    • Maroon MobileVR (with smart phones)
    • Maroon VR (HTC Vive / Oculus)

The original virtual lab:

Maroon VR

Abstract: Maroon VR is a three-dimensional immersive lab experience in VR. Different physics experiments are visualized and simulated and rendered in VR to engage learners in an innovative and emerging environment. Maroon VR is designed for two different learning scenarios: (1) a room scale virtual reality experience with the HTC Vive fully immerses learners into the lab. Learners experience a Tesla coil at close range and can interact with the electro-magnetic experiments and feel resistance through the controllers. The second (2) scenario implements the lab in fully mobile VR experiments with the Gear VR or Google Cardboard. Since most students already own a smartphone, this version is cost-effective and easily available and remotely and mobile usable. This version is designed to be used in the classroom and supports immersive and engaging learning in a mobile, stand-alone, and cost-effective way.
