Virtual reality (VR) companies develop software and hardware that immerse users in a three-dimensional, virtual world. Virtual worlds are created using wearable devices, such as head-mounted stereoptical displays or gloves with embedded sensors. Virtual reality also includes environments where users can interact with each other through computer-generated avatars. Magic Leap, a VC-backed VR startup, developed human computing interfaces and software technology designed to superimpose 3D computer-generated imagery over real-world objects.
