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.

- 4. Virtual Reality (VR) Virtual Reality (VR) is a computer-generated environment with scenes and objects that appear to be real, making the user feel they are immersed in their surroundings. OR VR Refers to generating a virtual environment or projection which creates a realistic experience but does not exist in reality.

- 7. How Does Virtual Reality (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

- 13. History of VR • 1930s – Science fiction story predicted VR The idea of a pair of goggles that let the wearer experience a fictional world through holographic, smell, taste and touch.
- 14. History of VR • 1950s – Morton Heilig’s Sensorama An arcade-style theatre cabinet that would stimulate all the senses, not only sight and sound.
- 15. History of VR • 1960 – The first VR Head Mounted Display by Morton Heilig Telesphere Mask (patented 1960) and was the first example of a head-mounted display (HMD), albeit for the non-interactive film medium without any motion tracking. • 1961 Headsight – First motion tracking HMD by Comeau & Bryan Incorporated a video screen for each eye and a magnetic motion tracking system, which was linked to a closed circuit camera.
- 16. History of VR • 1965 – The Ultimate display by Ivan Sutherland It simulates reality to the point where one could not tell the difference from actual reality. It included • A virtual world viewed through a HMD • Computer hardware to create the virtual word • The ability users to interact with objects in the virtual world.
- 17. History of VR • Beginning of VR: Jaron Lanier • Coined the Term ‘Virtual Reality’ • Created one of the first companies that sold VR based products • Considered one of the most influential computer scientists in VR history

- 20. Non Immersive VR • Computer-generated environments without the feel of immersion.
- 21. Fully Immersive VR • Give you 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 • A mixture of non-immersive and fully immersive virtual reality. • Provides users with a partially virtual environment.
- 23. Collaborative VR • Allows users to collaborate in virtual reality from remote locations. • The goal of this form of VR is to create collaboration between people.

- 26. How Does VR Work? • 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 VR Work? • 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.
