Virtual Reality
Virtual reality (VR) uses computer-generated environments to simulate realistic experiences. VR headsets use displays and lenses to create stereoscopic 3D images that trick the brain into perceiving the virtual environment as reality. Special hardware like head-mounted displays, motion trackers, and controllers allow users to interact with and immerse themselves in virtual worlds. The history of VR began in the 1930s with science fiction concepts, and continued to evolve with early head-mounted displays in the 1960s. Today, VR is used across many industries like gaming, real estate, education, and more.

OR VR Refers to generating a virtual environment or projection which creates a realistic experience but does not exist in reality.

How Does VirtualReality (VR) Work? • VR systems work by simulating as many senses as possible to trick the human brain into perceiving the virtual environment as reality. • Special Hardware components are used in VR: • Head-mounted Displays (HMDs) • Headphones with special audio • Gyroscopes, accelerometers and magnetometers for head and motion tracking • Controllers, gloves and treadmills

- 20. Non Immersive VR • Computer-generated environmentswithout the feel of immersion.
- 21. Fully Immersive VR • Giveyou a sense of being present in that virtual world and everything is happening to you for real. • Involves helmets, gloves, and body connectors with sense detectors.
- 22. Semi Immersive VR • Amixture of non-immersive and fully immersive virtual reality. • Provides users with a partially virtual environment.
- 23. Collaborative VR • Allowsusers to collaborate in virtual reality from remote locations. • The goal of this form of VR is to create collaboration between people.

- 26. How Does VRWork? • A head-mounted display (HMD) is put on by a user, the screen then moves along with the users head movements to create a simulated environment.
- 27. How Does VRWork? • VR headsets use either two LCD displays or have two different feeds being sent to one display. • Lenses that are placed between the screen and a user's eyes so images can be focused and reshaped. • This creates a stereoscopic 3D image by combining the different images.
