AUGMENTED REALITY
Introduction Augmented reality ◦ (^) Augmented reality system ◦ (^) Augmenting our world ◦ (^) Example – Wikitude ◦ (^) Example-Google glass Implementation Components of AR system Head mounted display Tracking & orientation

- (^) Augmented Reality is a field of computer research
which deals with combination of reality with computer generated data.
- (^) It is still in an early stage of research and
development, possibly by the end of this decade, we will see the first mass-marketed augmented-reality system.
An augmented reality system is
one that Combines real and
virtual world Is interactive in real
time Is registered in 3D.
Augmented Reality
System
WIKITUDE World Browser presents the
user with data about their surroundings, nearby landmarks, and other points of interest by overlaying information on the real-time camera view of a smart- phone.
- (^) Google Glass is a wearable computer with a head-mounted display (HMD) that is being developed by Google in the Project Glass research and development project.
- (^) Google Glass displays information in a Smartphone-like format hands-free , can interact with the Internet via natural language voice commands.
Here are the three components
needed to make an augmented-reality
system work:
Display Tracking system Mobile computing power
Compone
nts
Just as monitors allow us to see text and
graphics generated by computers,
head- mounted displays (HMDs) will
enable us to view graphics and text
created by augmented-reality systems.
There are two basic types of HMDS:
video see-through
optical see-through
Optical see through is not fully realized yet. It is supposed to consist of ordinary looking pair of glasses that will have light source on the side to project images onto the retina.

Currently, the best tracking technology
available for large open areas is the
Global Positioning System.
However, GPS receivers have an
accuracy of about 10 to 30 meters, which
is not bad in the grand scheme of
things, but isn't good enough for
augmented reality, which needs accuracy
measured in millimeters or smaller.
GPS Network
A digital compass consists of sensors to measure the earth's magnetic field, some conditioning of those sensor signals, and a microcontroller to interpret the data
Components
◦ (^) Three magnetic sensors ◦ (^) One tilt sensor
Wearable computers (^) Mobile computing can be accomplished with help of wearable computers
(^) A wearable computer is a battery powered computer system worn on the
user’s body(belt, backpack etc). (^) It is designed for mobile & predominantly hands free operations often
incorporating head mounted display & speech input.
