WHAT IS AUGMENTED REALITY…?

4.
INTRODUCTION
 Augmented Reality (AR) is a general term for a collection of technologies used to blend computer
generated information with the viewer’s natural senses.
 Augmented reality is the integration of digital information with the user's environment in real time.
 It works on computer vision based recognition algorithms to augment sound, video, graphics and
other sensor based inputs on real world objects using the camera of your device.
 Hardware components for augmented reality are processor, display, sensors and input devices.

VIRTUAL REALITY VS AUGMENTED REALITY

6.
HOW IT WORKS
 Augmented realities can be displayed on a wide variety of displays, from screens and monitors, to
handheld devices or glasses.
 Key Components to Augmented Reality Devices
 Sensors and Cameras
 Processing
 Projection
 Reflection

7.
HOW IT WORKS(CONT.)
 Sensors and Cameras
 Sensors are usually on the outside of the augmented reality device, and gather a user's real world
interactions and communicate them to be processed and interpreted.
 Cameras are also located on the outside of the device, and visually scan to collect data about the
surrounding area.
 Depth sensing cameras work in tandem with two "environment understanding cameras" on each
side of the device.
 Processing
 Augmented reality devices are basically mini-supercomputers packed into tiny wearable devices.
 These components include a CPU, a GPU, flash memory, RAM, Bluetooth/Wifi microchip, global
positioning system (GPS) microchip, and more.

8.
HOW IT WORKS(CONT.)
 Projection
 While “Projection Based Augmented Reality” is a category in-itself, we are specifically
referring to a miniature projector often found in a forward and outward-facing position on
wearable augmented reality headsets.
 Reflection
 Mirrors are used in augmented reality devices to assist with the way your eye views the
virtual image.
 The use of “mirrors” involves see-through holographic lenses (Microsoft refers to them
as waveguides) that use an optical projection system to beam holograms into your eyes.

DISADVANTAGES

 Diziness
 Distortion

16.
FUTURE SCOPE
 GPS and other in-car displays are great for getting us from point A to point B, and some
high-end vehicles even have displays on the windshield, but in the near future cars will be
able to identify external objects in front of the driver and display information about them on
the windshield.
 New and future systems will be able to display more information in the windshield.
