AUGMENTED REALITY

What is Augmented Reality?

Augmented reality is a combination of real scene viewed by a user and virtual scene generated by computer that augments the scene with sensory elements like visual, auditory, haptic, somatosensory, and olfactory. With the addition of these sensory elements we can enhance the user’s real-world experience.

Difference between Augmented Reality and Virtual Reality

Virtual reality completely isolate the user  from the real world so that user can’t interact with the real world. But, in the case of augmented reality user can involve in both real physical world and virtual world.

Technologies used in augmented reality

SLAM:

SLAM stands for simultaneous localisation and mapping. It is a sequence of  algorithms which use sensor data to construct a map of an unknown real environment while using it at the same time to identify where it is located.

Location based:

In this technology data about the location and augmented reality visualization are activated based on the data from GPS, digital compass, velocity meter which is embedded in the augmented reality device

Recognition based:

It is also called marker based augmented reality. In this technology camera is focused on certain points or some markers. Virtual visual is placed above these points

Projection based:

In this technology, augmented reality obtained by projecting artificially generated light in to  a real world environment

Super imposition based:

This technology  also uses object recognition technology in order to replace an entire real world object or a part of it with an augmented view

Display devices

• Head mounded display
• Eye glasses
• Contact lenses
• Virtual retina display
• Hand held
• Spatial

Futures of augmented reality

Education:

The graphics, video, audio can be combine into a students real time experience so that the classroom will be more interesting

Military

Augmented reality display could also inform soldiers the movement of enemies, and help them to move to where the enemy can’t see them

Medical purpose

Augmented reality helps surgeon by giving information about the heart beat rate, the blood pressure, the state of the patient’s organ, thus reduce risk in operation. By using augmented reality technology medical students can practice surgery in a controlled environment.

Travelling

By using GPS, digital compass, velocity meter in augmented reality devices, traveler can obtain the information about destination and current location through augmented reality display

Goal of Augmented Reality

Ultimate goal of augmented reality is to create a system in which user cannot identifies the virtual visuals in real world

Advantage

• It enhances knowledge of people
• It helps the people in sharing the experience over a long distance
• augmented reality based games gives more real experience

It help user to experience the world from our living room
