Augmented Virtual Reality
Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data. Remember Sky kids 3D, augmented virtual reality is sort of similar to that but so much cooler. Not really. Augmented reality is a way of boosting current observation of reality through the use of computer related stimuli. The aim of AR is to enhance the visual experience by enriching it and making it more interactive.

AR should not be confused with virtual reality. AR provides a better visually stimulating environment to interact with real world objects. The aim of augmented reality is not to provide an alternate reality. That is the function of virtual reality but as the name implies to support the consciousness we alreadyhave with our senses AR works by using existing technologies and integrating them into our real world environments. Examples of such technologies are sound, video and GPS data. The technologies that are mainly driving the use of technology are video games and cell phones at the moment.

Development of AR technology
The first AR device was invented at havard university by Ivan Sutherland. The phrase was first coined in the early nineties. It has existed in the most minute details since, examples are first down lines on a television screen during a football game. . The concept of augmented reality first appeared in fighter jets, in what was called a Head-Up Display. It involved symbols projected onto a transparent glass screen, allowing pilots to better aim their weapons. When a driver glances at the speedometer or gas gauge, they briefly take their eyes off the road in front of them. This was a distraction that pilots could not afford.

Instruments for Ar technology
AR Technology can be accesed through various media. Examples are head mounted displays, eye lenses, contact lenses.

Virtial retina display which is currently still in development at the university of washington. With this technology, a display is scanned directly onto the retina of a viewer's eye. The viewer sees what appears to be a conventional display floating in space in front of them.[23]

Hand held devices like mobile phones

Applications of AR technology

Examples of AR technology

AR can be used to aid archaeological research, by augmenting archaeological features onto the modern landscape, enabling archaeologists to formulate conclusions about site placement and configuration.[46] Another application given to AR in this field is the possibility for users to rebuild ruins, buildings, or even landscapes as they formerly existed.[47] [edit]Architecture

AR can aid in visualizing building projects. Computer-generated images of a structure can be superimposed into a real life local view of a property before the physical building is constructed there. AR can also be employed within an architect's work space, rendering into their view animated 3D visualizations of their 2D drawings. Architecture sight-seeing can be enhanced with AR applications allowing users viewing a building's exterior to virtually see through its walls, viewing its interior objects and layout.[48][49] [edit]Art

AR technology has helped disabled individuals create art by using eye tracking to translate a user's eye movements into drawings on a screen.[50] An item such as a commemorative coin can be designed so that when scanned by an AR-enabled device it displays additional objects and layers of information that were not visible in a real world view of it.[51][52] [edit]Commerce

AR can enhance product previews such as allowing a customer to view what's inside a product's packaging without opening it.[53] AR can also be used as an aid in selecting products from a catalog or through a kiosk. Scanned images of products can activate views of...
