What is Augmented Reality ??

The interactive experience of a real-world environment
See the direct or indirect views of physical real-world environments
Augmented with superimposed computer-generated images
over a user’s view of the real world, thus enhancing one’s the current Opinion of reality.
Used to add or enhance something on real things
Graphics, sounds, and touch feedback are added into
our natural world to create an enhanced user
experience

INVENTION OF AR SYSTEM

In 1968 -The Sword of Damocles-ØIvan Sutherland invented the first VR head-mounted display at Harvard University.

In 1975 -Videoplace-ØMyron Kruegercreated an artificial reality laboratory. The scientist envisioned the interaction with digital stuff by human movements

In 1980s –EyeTap-ØSteve Mann formulated the concept ofmediated reality (first portable computer) , by using cameras, processors, and display systems

In 1992 -Virtual Fixtures System-ØFirst functional AR system developed by Louis Rosenberg in U.S. Air Force

In 2000 –ARToolKit-ØHirokazuKato(Japanese scientist) developed and published –an open-source SDK. Later it was adjusted to work with Adobe.

In 2004 -helmet-mounted AR system-Trimble Navigation presented an outdoor .

In 2008 -AR Travel Guide-Wikitude made map for Android mobile devices.

In 2013 -Google Glass-Google beta tested this –with internet connection via Bluetooth.

In 2015 Windows Holographic and HoloLens-Microsoft presented two brand new technologies: with an AR goggles with lots of sensors to display HD holograms

In 2016 Pokemon Go game-Niantic launched this for mobile devices. The app blew the gaming industry up and earned $2 million in a just first week.

TYPES OF AUGMENTED REALITY

Marker BasedAR-Also called as Image Recognition,Uses a camera and some type of visual marker [QR /2D Code]

Marker-lessAR-Also called location-based, position-based Application

Uses a GPS, digital compass, velocity meter, or accelerometer which is embedded in the device to provide data based on your locationExample: Google Maps

Projection BasedAR-Works by projecting artificial light onto real world surfaces.Allow for human interaction by sending light onto a real world surface and then sensing the human interaction (i.e. touch) of that projected lightExample : (3D) interactive hologram into mid-air.

Superimposition BasedAR-Either partially or fully replaces the original view of an object with a newly enhanced view of that same object.object recognition plays a main role

Example :Ikea augmented reality furniture catalogue
