This is one of the first learning presentations that I had worked during my college days. Now, you can find more articles related to technology domain at https://www.biztechpost.com/

1. Augmented Reality

2. Virtual Reality...oh no VR, experience is one “in which the user is effectively immersed in a responsive virtual world.”

3. Augmented Reality (AR) A technology…and confluence of technologies A field of research A vision of future computing An emerging commercial industry A new medium for creative expression Augmented reality (AR) refers to the addition of a computer-assisted contextual layer of information over the real world, creating a reality that is enhanced or augmented. ELI Horizon Report, February 2011 Trying to imagine how augmented reality will be used is like trying to forecast the future of the web in 1994. The Economist Technology Quarterly, September 2009.

4. Augmented Reality WOW-NOW Augmented reality (AR) is a term for a live direct or indirect view of a physical real-world environment whose elements are merged with (or augmented by) virtual computer-generated imagery - creating a mixed reality. The augmentation is conventionally in real-time and in semantic context with environmental elements (Wikipedia)

5. Components of an Augmented Reality System

6. GPS and GIS Technology A global information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. This application is designed to provide the user easy capability to search one position in the world map like city name, place etc using a Web service. GIS can integrate and relate any data with a spatial component, regardless of the source of the data The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. Smartphones are taking market share from standalone personal navigation devices (PNDs)

7. Web 2.0 Originally in 2004, “Web as a platform". "cutting edge Web 2.0“. Web 2.0 is a Social Web Web 2.0 is an Interactive Internet What is Web 2.0?

9. Every word Hypertext Hypertext is intimately connected with the rise of the Internet as we know it today. The idea was implicitly described by Vannevar Bush in his pioneering article, "As we may think" (1945), and developed by Douglas Engelbart, who coined the term "text link" and linked the concepts of hypertext and multimedia to create the term "hypermedia" and later "open hyperdocument systems." The term "hypertext" was coined by Ted Nelson, who defined it in Literary Machines as "non-sequential writing.“ Nelson also drew attention to what he termed the framing problem of ordinary hypertext and in his Xanadu system accordingly called for a universal hypermedia environment. As to the origins of the concept Nelson claimed: "The hypertext is a fundamental document of Jewish religion and culture and the Talmudic scholar is one who knows many of its pathways.”

12. One of the main uses of augmented reality systems to the military is providing field soldiers crucial information about their surroundings as well as friendly troops and enemy movements in their particular area

13. Augmented reality systems will also play a big role in law enforcing and intelligence agencies

15. This will result in less risky and more efficient surgical operations.

17. Markers can be placed or attached to a particular object a person is currently working on so that project and site managers can monitor work in progress.

18. In the petroleum and mining industry, it will enable decision makers to make timely decisions.

20. 258 AR apps exist in the Android Market out of 130,000+ total Android apps

21. Browsers allow you to view augmented content – Junaio, Layar, and Wikitude World Browser

22. Editing tools allow you to augment your own reality – Tag What, Artags, and Sekai Camera

23. Educational tools help you learn by interacting with the environment around you – Google Goggles and Google Sky Map

25. An Introduction to AR Book An augmented book is an application that augments virtual 3D objects to a real book via AR technology Augmented Reality(AR) books are interactive paper-based books implementing some forms of physical-to-digital links where physical paper documents become augmentedly merged with digital content.

26. The main hardware elements of AR book system are display(PC monitor, HMD, handheld device, smart device), tracking, input device(marker, web-camera, and keyboard), and computer. The software technologies for AR book applications are divided by two: off-line software technologies such as ARToolKit, 3D Studio Max, and PaperVision3D; and real-time software technologies such as FLARManager of all the software libraries(Lizrokapis, 2007).

27. Types of AR book A Situated Learning Technique (SLT) in which the user access the contents by the OCR that couldn’t be edited. In applying SLT to AR book content, a major focus falls on the main components of SLT such as authentic context, affordable knowledge, active social interaction, and task/activities A Cognitive Load Theory (CLT) in which user can customize the text according to there choice In accordance with CLT, there are three different types of cognitive load, namely, intrinsic load caused by the complexity of the instructional goals and content, germane load originating from design of instructional materials in ways that contribute to learning, and extraneous load imposed by the elements of the instructional design itself that is irrelevant to the learning goal.

33. Optical see-through HMD

34. Artificial Reality indoor A conceptual drawing of a tracking system: Magnetic trackers vs vision-based trackers!!! The tracking system has two parts; specifically, six sensors that are attached to the user, and a set of light-emitting diodes attached to the ceiling. The sensors attached to the user look upwards at the ceiling, and from that position and knowing the location of the user sensors compared to the location of the LEDs, it is possible to calculate the precise position of the user in the room and project the virtual objects accordingly

38. ARToolKit ARToolKit is a software library for building Augmented Reality (AR) applications. These are applications that involve the overlay of virtual imagery on the real world. For example, in the image to the right a three-dimensional virtual character appears standing on a real card. It can be seen by the user in the head set display they are wearing. When the user moves the card, the virtual character moves with it and appears attached to the real object. One of the key difficulties in developing Augmented Reality applications is the problem of tracking the users viewpoint. In order to know from what viewpoint to draw the virtual imagery, the application needs to know where the user is looking in the real world. ARToolKit uses computer vision algorithms to solve this problem. The ARToolKit video tracking libraries calculate the real camera position and orientation relative to physical markers in real time. This enables the easy development of a wide range of Augmented Reality applications. Some of the features of ARToolKit include: * Single camera position/orientation tracking. * Tracking code that uses simple black squares. * The ability to use any square marker patterns. * Easy camera calibration code. * Fast enough for real time AR applications. * SGI IRIX, Linux, MacOS and Windows OS distributions. * Distributed with complete source code.

39. FLARToolKit * AS3 ported version of ARToolKit. * Actually, FLARToolKit is based on NyARToolkit, Java ported version of ARToolKit. * FLARToolKit recognize the marker from input image. and calculate its orientation and position in 3D world. * You should draw 3D graphics by your own. * But helper classes for major flash 3D engines (Papervision3D, Away3D, Sandy, Alternativa3D) are included. * Papervision3D is used in starter-kit. GPL FLARToolKit is free to use for non-commercial applications under the GPL license. This means the complete source code for your application must be made available to anyone that asks for it. FLARToolKit is based on the ARToolKit library under the GPL license and so the source code for any FLARToolKit applications that are made needs to be GPL as well.
