essay on augmented reality and virtual reality
Answers
Explanation:
Augmented reality has come a long way from a science-fiction concept to a science-based reality. Until recently the costs of augmented reality were so substantial that designers could only dream of working on design projects that involved it – today things have changed and augmented reality is even available on the mobile handset. That means design for augmented reality is now an option for all shapes and sizes of UX designers.
Augmented reality is a view of the real, physical world in which elements are enhanced by computer-generated input. These inputs may range from sound to video, to graphics to GPS overlays and more. The first conception of augmented reality occurred in a novel by Frank L Baum written in 1901 in which a set of electronic glasses mapped data onto people; it was called a “character marker”. Today, augmented reality is a real thing and not a science-fiction concept.
A Brief History of Augmented Reality (The Past)
Augmented reality was first achieved, to some extent, by a cinematographer called Morton Heilig in 1957. He invented the Sensorama which delivered visuals, sounds, vibration and smell to the viewer. Of course, it wasn’t computer controlled but it was the first example of an attempt at adding additional data to an experience.

Then in 1968, Ivan Sutherland the American computer scientist and early Internet influence, invented the head-mounted display as a kind of window into a virtual world. The technology used at the time made the invention impractical for mass use.
In 1975, Myron Krueger, an American computer artist developed the first “virtual reality” interface in the form of “Videoplace” which allowed its users to manipulate and interact with virtual objects and to do so in real-time.
Steve Mann, a computational photography researcher, gave the world wearable computing in 1980.
Of course back then these weren’t “virtual reality” or “augmented reality” because virtual reality was coined by Jaron Lainer in 1989 and Thomas P Caudell of Boeing coined the phrase “augmented reality” in 1990.
The first properly functioning AR system was probably the one developed at USAF Armstrong’s Research Lab by Louis Rosenberg in 1992. This was called Virtual Fixtures and was an incredibly complex robotic system which was designed to compensate for the lack of high-speed 3D graphics processing power in the early 90s. It enabled the overlay of sensory information on a workspace to improve human productivity
There were many other breakthroughs in augmented reality between here and today; the most notable of which include:
Bruce Thomas developing an outdoor mobile AR game called ARQuake in 2000
ARToolkit (a design tool) being made available in Adobe Flash in 2009
Google announcing its open beta of Google Glass (a project with mixed successes) in 2013
Microsoft announcing augmented reality support and their augmented reality headset HoloLens in 2015
Answer:
In Virtual Reality (VR), the users' perception of reality is completely based on virtual information. In Augmented Reality (AR) the user is provided with additional computer generated information that enhances their perception of reality.
For example, in architecture, VR can be used to create a walk-through simulation of the inside of a new building; and AR can be used to show a building's structures and systems super-imposed on a real-life view. Another example is through the use of utility applications.
Some AR applications, such as Augment, enable users to apply digital objects into real environments, allowing businesses to use augmented reality devices as a way to preview their products in the real world. Similarly, it can also be used to demo what products may look like in an environment for customers, as demonstrated by companies such as Mountain Equipment Co-op or Lowe's who use augmented reality to allow customers to preview what their products might look like at home through the use of 3D models.
Augmented Reality (AR) differs from Virtual Reality (VR) in the sense that in AR part of the surrounding environment is actually 'real' and just adding layers of virtual objects to the real environment. On the other hand, in VR the surrounding environment is completely virtual. A demonstration of how AR layers objects onto the real world can be seen with augmented reality games. WallaMe is an augmented reality game application that allows users to hide messages in real environments, utilizing geolocation technology in order to enable users to hide messages wherever they may wish in the world.
Such applications have many uses in the world, including in activism and artistic expression.
