RECENT ADVANCES IN APPLICATIONS OF AUGMENTED

REALITY‘”Reality is merely an illusion ,albeit a very

persistent one.’’

‘Reality’ – real world environment

‘Augmented’ – added or supplemented.

In Augmented reality, the real world environment is supplemented or augmented by virtual data like text, graphics or GPS data, etc. in real time.

AUGMENTED REALITY (AR)

The brain takes information from each eye, unites them into one picture – Gives the perception of depth (3-D)

With the development of 3-D display technology, the field of 3-D animation and virtual reality developed.

ORIGIN OF AUGMENTED REALITY

1) 3-D display :-

Stereoscopic View Relating or denoting a process by which two photographs of the same

objects taken at slightly different angles are viewed together, creating an impression of depth and solidity.

displaying left side and right side view.

Virtual Reality• The user’s physical presence is simulated in a

virtual environment.• The user is able to interact with the virtual

space by some devices, like Oculus, HTC Vive,

Augmented reality

• The system supplements the real world environment.

• The user maintains the sense of presence in the real world.

• needs a mechanism to combine virtual and real worls.

Virtual reality

• It has totally simulated virtual immersive environment.

• senses are under control of system. (most of the time only visual senses)

• Needs a mechanism to feed a virtual world into the senses of users.

DIFFERENCES BETWEEN AUGMENTED REALITY AND VIRTUAL REALITY

DEVELOPMENT PLATFORMS OF AUGMENTED REALITY

1. Marker-Based AR Marker-less AR

• A marker can be a 3D object, image, QR code, or human face too

• It uses GPS of mobile devices to record the device position and displays information relative to that location.

• After the AR system detects the target, the virtual object can be embedded on it and can be displayed

• It relies more on the capabilities of the device

EXAMPLES

Classifications of AR1. By augmenting the user2. By augmenting the physical

object3. By augmenting the environment

surrounding the user and the object

A person can wear a special kind of device, on the head or hand, which will give some information about the object, e.g., a head mounted display.

1.By augmenting the user

By augmenting an object, for example a cell phone with other devices like GPS.

Example:- In Netherlands, Layar app shows location based info about a building once camera is put towards that building.

2.By augmenting a physical object

3.By augmenting the environment surrounding the user and the object• Neither the user

nor the object is affected directly.

• The device superimposes and collects info about the surrounding environment, such as about the planned construction near a road.

Education :- students participate more interactively with computer generated simulations

,exploring each significant area of the event site.

Applications of Augmented reality

Medical field :- - medical students use this technology to practice surgery in a controlled environment

- It reduces risk of operations by giving the surgon improved sensory preprations.

Applications in Navigation• AR on navigation

devices can give us real time information being projected and interacted on real world elements. For example, Layar and Wikitude are two apps used for this application.

Construction and Architecture

O AR is used to make interactive models of buildings, construction sites, cables, blue prints of maps,etc.

AR is used to virtually see the interiors of the house exactly the way they have to be designed.

INTERIOR DESIGNING

Defense, Military, Search and Rescue

Heads-Up Display (HUD) is positioned in the pilot’s view. On this display altitude, airspeed, etc is displayed.

Augmented reality allows video game players to experience digital game play in real world environment.

Example – Niantic and eyeshot emerged as AR gaming creators. Nientic and is notable for releasing Pokémon go.

GAMING INDUSTRY

EXAMPLE : POKÉMON GO

Treatment 1) :- Manual printed on single sided sheetTreatment 2) :- CAI (computer assisted instruction) base on LCD and Monitor display.Treatment 3) :- CAI on seeing through HMD(head mounted displays)Treatment 4) :- Spatially registered Augmented reality

Survey on AR

Effect of Instructional Medium On the Time of CompletionThe effect of time of completion

depending on the instructional medium is statically significant.

Barriers we need to cross

Public awareness and reach of mobile AR Technological limitations Mobile internet connectivity in emerging markets Desktop is the primary interface right now it should be

improved

Future Scope of Augmented Reality

* AR is now has to come out of the labs to be used in daily life on mass level.

* Example: Sixth Sense- a wearable gestural interface developed by Pranav Mistry at MIT

* AR can be used as an alternative for the people who have lost one of their senses.

SixthSense technology

AR systems can improve task performance.

Very useful in developing the Sixth Sense technology.

Most innovative aspect of AR : its objective.
