Making virtual reality more accessible

VR systems use software and hardware to create and manage a virtual, interactive 3D environment that includes visual and sometimes audio and tactile elements. They generally include various types of display, sensor, and user-tracking and -navigation technologies. The systems can either simulate a real environment, such as a building, or create an imaginary one. Newer VR systems are less expensive and complex than their predecessors and thus are accessible by more people for simpler projects.
