2What is Virtual Reality (VR) ?Virtual Reality is a computer generated, multi-sensory information program which tracks a user in real time i.e. computer system is used to create an artificial world in which the user has the impression of being in that world ,with the ability to navigate through and manipulate objects in that world.3Virtual Reality ConceptsThe concepts behind virtual reality are based upon theories about : A long held human desire to escape the boundaries of the real world by embracing cyberspace. Once there we can interact with this virtual environment in a more naturalistic manner which will generate new forms of human-machine interaction (HMI).4Augmented (AR) & Mixed Reality (MR)5Augmented Reality (AR)Refers to a system in which the user views and acts within an enhanced version of the real world. The enhancements are virtual (computer- generated), and can include objects or information.

6Mixed Reality (MR)sometimes referred to as hybrid realityencompassing both augmented reality and augmented virtualityrefers to the merging of real and virtual worlds to produce new environments and visualisations where physical and digital objects co-exist and interact in real time7

13TYPES OF AR

Marker-based ARMarkerless ARGPS & Compass Technology14MARKER BASEDMarker-based AR uses a camera and a visual marker to determine the center, orientation, and range of its spherical coordinate system.

Most of the time, the applications using markers are based on open source technology.

ARToolkit is the first fully-featured toolkit for marker-based AR

It has the advantage to be easily affordable but sometimes it is not supported and fairly weak

Total Immersion provides the worlds most widely used commercial augmented reality platform.

TYPES OF AUGMENTED REALITY

15MARKER LESS TRACKINGThis is currently one of the best technology for tracking

It performs active tracking and recognition of real environment on any type of support without using special placed markers.

Allows more complex applications of Augmented Reality.

16GPS and Compass Technology :Found in smartphones and tabletsUses devices' GPS, compass features and high-speed wireless networks Allows more complex applications of Augmented Reality. Main Attraction:Limitation:Provides useful local web-content information and added services in 2D format at the geo-location of the userFairly imprecise due to current inaccuracy of the GPS technology

20Medical ApplicationsA research team used Augmented Reality to cope with a 25-year-old womans cockroach phobia. Virtual cockroaches were displayed on the womans hands. After some sessions, her phobia for cockroaches has been eliminated.

21Characteristics of ARIt combines real and virtual World

It is interactive in real time

It is registered in 3D.

22Hardware needed for AR.Display

Tracking (GPS, compass)

Input devices (Camera)

sensors (accelerometer)

processer (CPU, any operating system or software)

GOOGLE GLASSGoogle Glass is a wearable computer with an optical head mounted display (OHMD). It was developed by Google.Using Augmented Reality Technology.24

28Advantages of ARAR Improve interactionAdvances in technologyMilitary Trainings which could be less expensiveRapid augmentation in tourism.Effective in Medical Field.Easy to locate desired places.A Good way of teaching.Increased the learning abilities.29Disadvantages of ARThree dimensional, real-time running augmented reality programs like "first person shooters" have been believed to increase teen aggression because they normalize violence.The lack of privacy.Difficult to maintain Augmented Reality Systems.Augmented reality is leading to an era of no privacy, where criminals could simply point their phone at victims and learn anything they need to know about them.

Google Glasses and Augmented ID or any other face detection application effect the privacy of humans.31CONCLUSIONAugmented reality (AR) is a way of delivering entertainment media that uses computer generated graphics transposed over real-life scenes.Create a system such that User CANNOT tell the difference between the real world and the virtual augmentation of it.To add information and meaning to a real object or place. Use of Medical Application increased and save the life of humans.But developers should controls the privacy. People thinks Augmented reality is leading to an era of no privacy, where criminals could simply point their phone at victims and learn anything they need to know about them.
