The European Union has granted regulatory approval to the first mixed reality flight simulator for pilot training, marking a milestone in aviation training. The simulator, developed by BRUNNER Elektronik and deployed at Lufthansa Aviation Training's facility in Switzerland, has met the European Union Aviation Safety Agency (EASA) standards for real-world pilot training. The Varjo XR-4 headset is a key component supporting this EU-certified mixed reality flight simulator. Meanwhile, several major technology companies including Meta, Apple, Samsung, Snap, Google, Sony, Microsoft, Panasonic, LG, IBM, VividQ, HTC, Lumus, and Intel have recently filed numerous patents related to virtual reality (VR) and augmented reality (AR) technologies. These patents cover a wide range of innovations such as headset display cooling systems, wide-band antennas, 3D data effects, glare compensation, adaptive frame rate adjustments, facial synthesis, spatial video capture, privacy screens, eye tracking, power-efficient displays, and holographic systems. This surge in VR and AR patent activity highlights the ongoing advancements in immersive technologies across multiple sectors.
