Virtual reality VS Augmented Reality
The document distinguishes between virtual reality (VR) and augmented reality (AR), with VR creating immersive, simulated environments and AR overlaying digital information onto the real world. It traces the history and applications of both technologies, noting VR's roots in the 1950s and AR's commercial debut in the late 1990s. The document concludes that while VR is more mature, AR holds potential for future interactions with both real and virtual environments.

- 1. VIRTUAL REALITY VS AUGMENTED REALITY DESIGNED BY: M. JAHANGIR KIYANI
- 2. WHAT IS VIRTUALREALITY • “The computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors”
- 3. WHO INVENTED VIRTUALREALITY? • More than one person has been involved in the development of this technology but if we are talking about the realm of virtual experience then the answer is Morton Heilig. • He produced the first interactive film experience in which viewers were invited to watch a film which would use all of their senses. This multi-sensory experience was the first ‘3D film’ which was designed for a single viewing only and enabled the viewer to become part of the film. For example: he used an oscillating fan so that the viewer could feel wind blowing on their face. • Virtual reality is considered to have begun in the 1950’s but early elements of it can be traced back to the 1860’s and long before the development of digital technology • The Virtual Reality Modelling Language (VRML), first introduced in 1994, was intended for the development of "virtual worlds" without dependency on headsets.
- 4. WHY WE NEEDVR Virtual reality is needed because complex scenarios can cause serious issues. Like complex brain surgery, flying aircraft training etc. For these kind of dangerous scenarios simulated environment is created ,to overcome the loss jand also create less cost as compared to original .
- 5. WORKING ELEMENTS FORVR DEVICES: Opinions differ on what exactly constitutes a true VR experience, but in general it should include: • Three-dimensional images that appear to be life-sized from the perspective of the user • The ability to track a user's motions, particularly his head and eye movements, and correspondingly adjust the images on the user's display to reflect the change in perspective
- 6. TYPES • Enhanced Reality •Desktop Virtual Reality • Telepresence • Immersive Virtual Reality
- 7. AFFECTS OF VRON USERS LIFE • Disruption of perceptual and sensory motor activities. • Disequilibrium. • Disorientation. • Drowsiness. • Cybersickness.
- 8. DEVICES USED FORVR • Personal Computer (PC)/Console/Smartphone • Vive • Oculus • Audio • Human Perception devices. • Googgles.
- 9. APPLICATIONS OF VR Virtualreality applications can be divided into: • The simulation of real environments such as the interior of a building or a spaceship often with the purpose of training or education • The development of an imagined environment, typically for a game or educational adventure
- 10. APPLICATIONS OF VR Areasin which Virtual Reality applications are commonly used : • Design Evaluation (Virtual Prototyping). • Planning and Maintenance. • Concept and Data Visualization. • Operations in hazardous or remote environments. • Training and simulation. • Entertainment and Leisure.

- 12. AUGMENTED REALITY “Augmented realityis the integration of digital information with the user's environment in real time”
- 13. WHAT IS AR? Unlikevirtual reality, which creates a totally artificial environment, augmented reality uses the existing environment and overlays new information on top of it.
- 14. HISTORY • Boeing researcherThomas Caudell coined the term augmented reality in 1990, to describe how the head-mounted displays that electricians used when assembling complicated wiring harnesses worked. One of the first commercial applications of AR technology was the yellow "first down" line that began appearing in televised football games sometime in 1998. • Today, Google glass and heads-up displays in car windshields are perhaps the most well-known consumer AR products, but the technology is used in many industries including healthcare, public safety, gas and oil, tourism and marketing.

- 16. AR is dividedinto five categories: 1. Projection based AR 2. Recognition based AR 3. Location based AR 4. Outlining AR 5. Superimposition based AR Types of AR
- 17. DEVICES USED FORAR • Tablets • Smartphones • HoloLens • User Perception Equipment
- 18. APPLICATIONS OF AR •Architecture • Medical • Military • Design • Education • Media And Communication • Entertainment
- 20. Augmented Reality isa mix of real world and the virtual world. It lets people interact with both worlds and distinguish clearly between both. This is generally achieved by holding a smartphone in front of us. Virtual reality creates an entire virtual world In this case ,it is hard to differentiate between what is real and what is not real This is generally achieved by wearing a helmet or goggles AUGMENTED REALITY VS VIRTUAL REALITY
- 21. CONCLUSION AR is farbehind then Virtual reality in maturity .Accuracy is required for success of AR ,which is quite difficult .However still AR has great future as it promises better interaction with real and virtual world.
