Virtual reality (VR) is a 3D computer-generated environment that can simulate realistic or imaginative worlds. VR immerses users in virtual environments through specialized headsets or mobile devices. The technology was first invented in the 1960s but has seen recent growth in applications like gaming, education, and tourism. In the hospitality industry specifically, VR allows users to take virtual tours of hotels and destinations or book travel arrangements without leaving home. It also has potential benefits for employee training by developing empathy for customer and staff experiences.
