Transcript of Augmented Reality

AUGMENTED REALITY A.R is a live, direct or indirect view of a physical, real-world environment whose elements
are augmented by computer-generated sensory input such as sound, video, graphics or
GPS data.



Basically it is superimposing computer generated graphics with the real world,combination of
virtual and the live view of the world.

As a result, the technology functions by enhancing one’s current perception of reality. What is Augmented Reality ?

1.AR app recognizes marker from web cam data.








2.App places 3D object (with transformations)on every frame. How does A.R actually work ? AR technology includes head-mounted displays and virtual retinal displays for

visualization purposes, and construction of controlled environments containing

sensors and actuators.

Display:
A head-mounted display (HMD) places images of both the physical world and registered virtual
graphical objects over the user's view of the world. Hardware components: processor , CPU , display , MEMS sensors such as accelerometer,GPS ,
camera Technology involved in A.R: Hardware Components :

Processor, display, CPU, camera and MEMS sensors such as

accelerometer, GPS, solid state compass.
1.Sports:
AR is used to display the yellow "first down" line in television broadcasts of American football games.
The real-world elements are the football field and players, and the virtual
element is the yellow line, which augments the image in real time. It is also used to display offside situations in football games. Medical:

AR can provide the surgeon with information of the heartbeat, the blood pressure,the state of the patient’s organ, etc.
A.R is also used by doctors while performing operations on patients.
Medical students use the technology to practice surgery in a controlled environment.

Visualizations aid in explaining complex medical conditions to patients. Augmented reality can reduce the risk of an operation by giving the surgeon improved sensory perception. This technology can be combined with MRI or X-ray systems and bring everything into a single view for the surgeon. Navigation: Information can be displayed on the car's windshield indicating information of where the user is going. Not only can information of how to get to the place be offered but so can information about the weather or the terrain. AR can provide traffic information to drivers. A.R also highlight objects on the road that might not be caught by the driver’s eyes at a first glance.

Ben Sequeira With the help of advanced AR technology the information about the surrounding real world of the user becomes interactive and digitally manipulable.

Artificial information about the environment and its objects can be overlaid on the real world. GAMING MILITARY
1.location -with GPS on maps
2.live video-camera
3.visual recognition software-
identifies real world objects with GPS data
4.layer software-add virtual data on top of real
world How A.R works: There are essentially 3 different kinds of displays of augmented reality:

1.The head mounted display (HMD) is worn on the head or attached to a helmet. This display can resemble goggles or glasses. In some instances, there is a screen that covers a single eye.

2. The handheld device is a portable computer or mobile smartphone such as the iPhone.

3. Spatial display makes use of projected graphical displays onto fixed surfaces. Let's take a look at the various applications of A.R in various fields: A.R technology allows fans to easily identify their favorite drivers on television.

It also captures all telemetry and positioning (speed, acceleration/deceleration, time behind leader, exact car position within 4cm, RPM, brake indicator, throttle percentage) and creates a digital record of the event in real time. A transparent display is positioned directly in the fighter pilots view. Data typically displayed to the pilot includes altitude, airspeed and the horizon line in addition to other critical data. The term "heads-up" comes from the fact that the pilot doesn't have to look down at the aircraft's instrumentation to get the data they need. The Head-Mounted Display (HMD) is used by ground troops. Critical data such as enemy location,land mines etc can be presented to the soldier within their line of sight. This technology is also used for simulations for training purposes. With recent advances in computing power and technology, gaming applications in augmented reality are on the upswing. Head worn systems are inexpensive and computing power is more portable than ever. In Zombie ShootAR from Metaio, the player uses a mobile phone to shoot zombies crawling around anywhere, anytime. The zombies are superimposed on your mobile phone in this 1st person shooter game. Metaio describes this game as an early example of what is possible in augmented reality. Entertainment: Education: Why continue research in AR? 1.AR systems will instantly recognize what someone is looking at, and
retrieve and display the data related to that view.

2.There are hundreds of potential applications for such a technology,
gaming and entertainment being the most obvious ones.

3.Any system that gives people instant information, requiring no
research on their part, is bound to be a valuable to anyone in any
field. Augmented Reality (AR) has been listed as an up-and-coming education technology. Text, graphics, video and audio can be superimposed into a student’s real time environment. Textbooks, flashcards and other educational reading material can contain embedded “markers” that, when scanned by an AR device, produce supplementary information to the student rendered in a multimedia format. THANK YOU..... A.R helps in blending the real character and background with computer generated cartoon characters. Screenshot from the movie“Who Framed Roger Rabbit?” Movies which demonstrated use of A.R: Iron Man Avatar and many more.... The changing maps behind weather reporters is also achieved with the help of augmented reality.
