AUGMENTED REALITY (AR)

Introduction to AR
¨ The idea of AR is to combine or mix the view of the real environment with additional virtual content that is presented through computer graphics. ¨ Augmented reality (AR) is a form of emerging technology that allows users to overlay computer generated virtual graphical content in the real world. ¨ AR refers to a live view of a physical real-world environment whose elements are merged with augmented computer- generated images creating a mixed reality.
¨ Through augmented vision, the information about the
surrounding real world helps the user can digitally interact
with and adjust information about their surrounding
environment.
¨ Augmented reality is the integration of digital
information with the user's environment in real time.
¨ Example: Snapchat

¨ VR tricks your senses into thinking you are in different environment or world apart from real world ¨ VR is a general term for immersive experiences and content via a VR headset or HMD (head-mounted display). ¨ It refers to computer technologies using reality headsets to generate realistic sounds, images and other sensations that replicate a real environment or create an imaginary world. ¨ The content is 100% digital and computer-generated. It is also called a computer-simulated reality.
And what is VR?
¨ Advanced VR environment engage all five senses ( taste , sight , smell , touch , sound ), but it is important to say that this is not always possible ¨ Most VR Devices tethered which are connected to a computer and some of them are standalone devices like Google Cardboard is among the most popular) and the remaining's are Smartphone VR. ¨ Using VR devices such as HTC Vive, Oculus Rift or Google Cardboard, users can be transported into a number of real- world and imagined environments
And what is VR?
¨ VR technology creates an environment in which the user feels and seems to be moving inside a computer-created virtual world in the same way people move inside the natural environment.
¨ Example: dragons

¨ The first Augmented Reality Systems (ARS) were
usually designed with a basis on three main blocks.
¨ Infrastructure Tracker Unit ¨ Processing Unit ¨ Visual Unit

¨ Infrastructure Tracker Unit : is responsible for collecting data from the real world, sending them to the Processing Unit. ¨ Processing Unit: which mix the virtual content with the real content and sent the result to the Video Out module of the Visual Unit. ¨ Visual Unit: the Visual Unit can be classified into two types of system, depending on the followed visualization technology: video see through and optical see through

1. Video see-through: It uses a Head-Mounted Display
(HMD) that employs a video-mixing and displays the
merged images on a closed-view HMD.

2. Optical see-through : It uses an HMD that employs
optical combiners to merge the images within an open-view
HMD.
