Virtual reality (VR) is a simulated, interactive, three-dimensional environment that can simulate physical presence in real or imagined worlds. VR was first created in the 1980s and has since been used for applications in entertainment, education, manufacturing, and medicine by creating immersive experiences that seem indistinguishable from real environments. As computing power continues to rapidly increase according to Moore's Law, VR is expected to become a widespread technology available for use in homes by the year 2037.

Virtual reality (VR) is a computer technology that uses Virtual reality headsets, sometimes in combination with physical spaces or multi-projected environments, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary environment. A person using virtual reality equipment is able to "look around" the artificial world, and with high quality VR move about in it and interact with virtual features or items. VR headsets are head-mounted goggles with a screen in front of the eyes. Programs may include audio and sounds through speakers or headphones.

Virtual reality is, plainly speaking, seeing an imaginary world, rather than the real one. Seeing, hearing, smelling, testing, feeling. The imaginary world is a simulation running in a computer. The sense data is fed by some system to our brain.
This presentation is all about augmented and virtual reality. It discusses what it is, examples of it, advantages, disadvantages, and has a quiz at the end to check if you learned from it.
Virtual Reality refers to a high-end user interface that involves real-time simulation and interactions through multiple sensorial channels. Virtual Reality is often used to describe a wide variety of applications, commonly associated with its immersive, highly visual, 3D environments. The development of CAD software, graphics hardware acceleration, head mounted displays, database gloves and miniaturization have helped popularize the concept. Jaron Lanier coined the term Virtual Reality in 1987. Today Virtual Reality plays a big part in the everyday lives of the world’s population.

These slides use concepts from my (Jeff Funk) course entitled Biz Models for Hi-Tech Products to analyze the business model for augmented reality software in the furniture industry. This software, in the form of a mobile app, enables users to envision new furniture in their home. After picking a scene from their home, users can download a 3D image of furniture from an online furniture’s web site into the app, and change the furniture’s position and color. The customers for the software are online retailers and furniture buyers. The value proposition for the user is better purchase decisions and for the on-line retailer is fewer returns. Possible methods of value capture include sales of the app to online retailers, pay per click, and commissions per sale of furniture to end users. Intellectual property and network effects are the possible barriers to entry and thus methods of strategic control.

Aslam.o.aliakum!
i am shakaib ashraf this topic is for my students who want to do presentation on virtual reality
introduction
types of virtual reality
how virtual reality works
these topics are available in this presentation
pray for me
thankyou
This presentation describes and defines Virtual Really.
Its also mentions some of its ongoing research for its viable usage in the field of electrical engineering.
It was done a school project.
And the information was collected sources available on the internet.
1. “So a virtual reality is a synthetic sensory
experience which may one day be
indistinguishable from the real physical
world “
- Kalawsky, R.S. (1993)
2. Introduction
Virtual Reality (VR) is the illusion of a threedimensional, interactive, computer-generated reality where
sight, sound, and sometimes even touch are simulated to
create pictures, sounds, and objects that actually seem real.
5. History of virtual reality
•1980s
• The term ‘virtual reality’ was created and popularized.
• Company named ‘VPL Research’ launched and produced goggles and gloves.
•
1990s
• NASA scientist designed virtual reality system to control Mars
rover from Earth.
6. What is VR?
• emulating the real world
• making an electronic world seem real
Interactive
• not static 3D images
• not movies
• moving within the world
• manipulating objects in the world
7. Inside VR
• scenes projected on walls
• realistic environment
• hydraulic rams!
• real controls
• other people
12. Hardware used in VR
Input devices:
A variety of input devices allow the user to navigate through a
virtual environment and to interact with virtual objects.
Directional sound, tactile and force feedback devices, voice
recognition and other technologies are being employed to
enrich the immersive experience and to create more
"sensualized" interfaces.
13. Input Devices (Motion Trackers)
The Motion Tracking system is based on magnetic sensors which are attached to the
user. Most common are sensors measuring the intensity of a magnetic field generated
at a reference point. The motion of the different segments is tracked using magnetic
sensors . These sensors return raw data (e.g. positions and orientations) expressed in
a single frame system..
14. Other Input Devices
MIDI keyboard
A MIDI keyboard controller has 88 keys, any of which can be struck within a fraction of second.
Each key transmits velocity of keystroke as well as pressure after the key is pressed.
Real-time video input
SIRIUS® Video card from Silicon Graphics. With SIRIUS®, images are digitized at a frequency of 25
Hz (PAL) or 30 Hz (NTSC) and may be analyzed by the VR program.
Real-time audio input
Speech synthesis facilities are of clear utility in a VR environment especially for command
feedback. Although speech synthesis software is available even at the personal computer
level, some improvement is still needed, particularly in the quality of speech.
15. Output Devices
Head-mounted displays (HMDs)
The head-mounted display (HMD) was the first device providing its wearer with an
immersive experience. A typical HMD houses two miniature display screens and an
optical system that channels the images from the screens to the
eyes, thereby, presenting a stereo view of a virtual world. As a result, the viewer can
look around and walk through the surrounding virtual environment.
16. BOOM (Binocular Omni-Orientation
Monitor)
The BOOM (Binocular Omni-Orientation Monitor) from Fake space is a head-coupled
stereoscopic display device. Screens and optical system are housed in a box that is
attached to a multi-link arm. The user looks into the box through two holes, sees the
virtual world, and can guide the box to any position within the operational volume of
the device.

24. The Future of Virtual Reality
Virtual Reality is a growing industry
PC and specialized hardware are getting better, faster and cheaper
because of development in VR.
Maybe 3D user interfaces will replace the present computers.
Huge demand for VRML programmers in near future.
Revolution in gaming industries
25. Future
In the past, computing power has
doubled
approximately every 18
months, a trend that is known as
Moore’s Law. If this is the case then we
should have a computer powerful
enough to run immersive VR programs
in our own homes by the year 2037.
