Foto de stock - 24 March 2023, Saxony-Anhalt, Halle (Saale): Former swimmer and world champion Paul Biedermann (l) has virtual snorkeling explained to him by Bernd Kaltenbach at the Maya mare swimming paradise in Halle/Saale. In cooperation with two other partners, Kaltenbach's company Kabetec from Schonach, Germany, has developed waterproof VR goggles that use special lenses and a special tracking system to allow users to dive into a 3D animated world. The goggles with integrated snorkel transport the bather into a coral landscape with dolphins and a shipwreck in a pool set aside for this purpose. The company from the Black Forest has also developed special glasses for other areas, such as museums or roller coasters in amusement parks.
