Augment /ɔːɡˈmɛnt/ It means

To make (something already developed or well under way) greater, as in  size,  extent, or quantity

Augmented reality o Augmented reality (AR) is a live direct or indirect view of a physical, real-

world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data.

• It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality.

 By contrast, virtual reality replaces the real world with a simulated one.  Augmentation is conventionally in real-time and in semantic context with

environmental elements, such as sports scores on TV during a match. With the help of advanced AR technology (e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes interactive and digitally manipulable. Artificial information about the environment and its objects can be overlaid on the real world.

Augmented reality in Gaming Augmented reality allows gamers to experience digital

game play in a real world environment. In the last 10 years there has been a lot of improvements in technology, resulting in better movement detection and the possibility for the Wii to exist, but also direct detection of the player's movements.

Things that are require for playing game are :

Head mount display Eye glasses Joypad

This is one of game played by using augmented reality technology .this game is being played in the parking lot. Games become very realistic and interesting …

Augmented reality in education

Visual and highly-interactive forms of learning

Digital Media- superimposed into a student’s real time environment

Interactive participation with computer generated simulations of historical events

Learning via remote collaboration

Signification in Education

Provides rich contextual learning for individuals learning a skill.

Students take control of their own learning.

Appeals to multiple learning styles.

Engages learner in ways that have never been possible

No real consequences if mistakes are made during skill training

Shifts learners from passive to active learning modes.

Augmented reality in Medical

Since 2005, a device that films subcutaneous veins, processes and projects the image of the veins onto the skin has been used to locate veins. This device is called Vein Viewer.

Augmented Reality can provide the surgeon with information, which are otherwise hidden, such as showing the heartbeat rate, the blood pressure, the state of the patient’s organ, etc. AR can be used to let a doctor look inside a patient by combining one source of images such as an X-ray with another such as video.

Examples include a virtual X-ray view based on prior tomography or on real time images from ultrasound and confocal microscopy probes, visualizing the position of a tumor in the video of an endoscope, or radiation exposure risks from X-ray imaging devices. AR can enhance viewing a fetus inside a mother's womb. It has been also used for cockroach phobia treatment. Also, patients wearing Google Glass can be reminded to take medications.

Navigation

AR can improvise the effectiveness of navigation devices. Information can be displayed on an automobile's windshield indicating destination directions and meter, weather, terrain, road conditions and traffic information as well as alerts to potential hazards in their path. Aboard maritime vessels, AR can allow bridge watch-standers to continuously monitor important information such as a ship's heading and speed while moving throughout the bridge or performing other tasks.

BMW steps into augmented reality with AR driving glasses for Mini

The glasses are powered by a Qualcomm 805 Snapdragon processor, have 2GB of RAM and are equipped with two HD displays. Drivers activate and control functions via buttons on the top of the frames.

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; this was demonstrated publicly by Trimble Navigation in 2004. 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.

Augmented reality markup language The Augmented Reality Markup Language (ARML) is a data standard to describe and interact with augmented reality (AR) scenes. It has been developed within the Open Geospatial Consortium (OGC) by a dedicated ARML 2.0 Standards Working Group. ARML consists of both an XML grammar to describe the location and appearance of virtual objects in the scene, as well as ECMAScript bindings to allow dynamic access to the properties of the virtual objects, as well as event handling, and is currently published in version 2.0. ARML focuses on visual augmented reality (i.e. the camera of an AR-capable device serves as the main output for augmented reality scenarios).

Advantages of Augmented reality It can be used used easily with

help of some simple gestures We can feel what be see/watch

(ex: Movies). Can perform repetitive tasks. Brings life to games and

entertainment. Used for military training. Architecture and interior designs Engineering designs Presentations

Disadvantages of Augmented reality

Limited use only . lack of privacy decreases imaginative & creative skills

Microsoft's HoloLens to help NASA scientists explore Mars

For $279 you can buy a version of the headset (which has about two hours of battery life) that allows you to place your iPhone 6 or Android phone into the headset for VR functionality (much like the Samsung Gear VR). And for $359 you get the all-in-one version of the device (with about one and a half hours of battery life), which has its own built-in display (no mobile phone necessary).
