Augmented Reality and Virtual Reality

 Augmented Reality is a technology that superimposes computer generated images on the users view of the real world thus providing a composite view.

Augmented Reality

is when digital information is overlaid onto the actual physical world.

Your camera detects a target image, and can figure out how close or far, and at what angle, the target image is form the camera using sensors.

It then projects digital information onto that target image, and voila - augmented reality.

Augmented Reality

device name are -

Meta 2

Example :

Snapchat : Snapchat has recently added augmented reality to their features with the new lense filters.

Let's switch over to see exactly how this works.

There are different types of Augmented Reality :-

Marker-based Augmented Reality - use any marker

Marker-less Augmented Reality - no use marker and location less AR

Projection based Augmented Reality - use small projector

Superimposition based - Replace original view to another.

Some of the earliest uses of augmented reality were the head-up displays on figure jets, allowing pilots to see important projected in front of them on their windshields.

This technology eventually made its way to automobiles, and even your eye glasses with google glasses.

There are many apps you can download right now that utilize augmented reality.

Yelp : It has a feature called Monocle that let's you see restaurant review and information around you.

SnapShop : This app uses augmented reality to show you how furniture will in your room before you buy.

AR Zombies : ARZombies lets you shoot zombies around the office like you're Rick from the Walking day.
One of the most impressive uses of AR for gaming came with the announcement of the Microsoft Hololens.

The Hololens uses advanced sensors and hardware to scan your room, and creates images based on your physical space.

You can interact with these images, and see them from different angles using the hololens headset.


Virtual Reality

is a fully impressive computer simulated technology generated with the help of realistic images, sound and other sensations.

The main sensors VR headsets are :-

* Magneto meter - magnetic field
* Accelerator meter - X,Y,Z Axis of phone
* Gyroscope sensor - Accurate by 360

At its most basic level, virtual reality is an experience generated by a computer meant to stand in for the physical reality around us.

Computer scientist Jaron Lanier is often credited with coining the term Virtual Reality in the 1980s, but the discipline of VR is a collection of ideas that date back nearly a century.

At the heart of virtual reality are two concepts :

immersion and interaction.

Immersion :- Its refer to your sense of presence within a virtual world. If that information is consistent, reliable and convincing, our brains accept it as reality. And the more senses you can engage, the better.

With virtual reality, we're usually talking about sight and sound. But some VR setups also engage our sense of touch in what's called haptic feedback.

As for interactivity, that's all about to what extent you can affect the virtual world around you.

Are you a passive audience, or can you interact with the objects, creatures, people and environment ?

Generally speaking, the more interactive the experience, the more convincing it is.

Both immersion and interaction create the illusion that you're in a different world.

That illusion can be broken if the experience suffers from technical issue, lag (which we call latency in VR), or limitation in what you are allowed to do once you;re in the VR world
