Augmented reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real-world are "augmented" by computer-generated perceptual information, sometimes across multiple sensory modalities, including visual, auditory, haptic, somatosensory, and olfactory.The overlaid sensory information can be constructive (i.e. additive to the natural environment) or destructive (i.e. masking of the natural environment) and is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, whereas virtual reality completely replaces the user's real-world environment with a simulated one. Augmented reality is related to two largely synonymous terms: mixed reality and computer-mediated reality.

  9. 9. What is augmented reality(A.R)? A view of physical real-world environment with superimposed computer-generated images, thus changing the perception of reality, is the AR. Augmentedrealityis the technology thatexpandsour physicalworld, addinglayersof digitalinformation ontoit. AugmentedReality(AR)refersto deployingvirtualimageover real-worldobjects.
  10. 10. History and Development  AR in 1960s.  In 1968 Ivan Sutherland and Bob Sproull created a first head-mounted display, they called it The Sword of Damocles  It was a rough device that displayed primitive computer graphics.
  11. 11.  AR in 1970s. In 1975 Myron Krueger created Videoplace – an artificial reality laboratory. The scientist envisioned the interaction with digital stuff by human movements. This concept later was used for certain projectors, video cameras and onscreen silhouettes.
  12. 12.  AR in 1980s  . In 1980 Steve Mann developed a first portable computer called EyeTap, designed to be worn in front of the eye. It recorded the scene to superimposed effects on it later, and show it all to a user who could also play with it via head movements.  In 1987 Douglas George and Robert Morris developed the prototype of a heads- up display (HUD). It displayed astronomical data over the real sky.
  13. 13.  AR in 1990s. Year 1990 marked the birth of the “augmented reality” term. It first appeared in the work of Thomas Caudell and David Mizell – Boeing company researchers.  In 1992 Louis Rosenberg of the US Air Force created the AR system called “Virtual Fixtures”.  In 1999, a group of scientists led by Frank Delgado and Mike Abernathy tested new navigation software, which generated runways and streets data from a helicopter video.
  14. 14. AR in 2000s.  In 2000 a Japanese scientist Hirokazu Kato developed and published ARToolKit – an open- source SDK. Later it was adjusted to work with Adobe. In 2004 Trimble Navigation presented an outdoor helmet-mounted AR system. In 2008 Wikitude made the AR Travel Guide for Android mobile devices.
  15. 15.  AR today.  In 2013 Google beta tested the Google Glass – with internet connection via a Bluetooth.  In 2015 Microsoft presented two brand new technologies: Windows Holographic and HoloLens (an AR goggles with lots of sensors to display HD holograms).  In 2016 Niantic launched Pokemon Go game for mobile devices. The app blew the gaming industry up and earned $2 million in just first week.
  16. 16. How A.R works?  What is Augmented Reality for many of us implies a technical side, i.e. how does AR work. For AR a certain range of data (images, animations, videos, 3D models) may be used and people will see the result in both natural and synthetic light. Also, users are aware of being in the real world which is advanced by computer vision, unlike in VR.  AR can be displayed on various devices: screens, glasses, handheld devices, mobile phones, head-mounted displays. It involves technologies like S.L.A.M. (simultaneous localization and mapping), depth tracking (briefly, a sensor data calculating the distance to the objects), and the following components:
  17. 17. Working Capturing module : captures image from the camera Tracking module:calculates the correct location and orientation of for virtual overlay. Rendering module :combines the original image and the virtual components and renders the AR image on the display.
  18. 18. Sensors/tracking: It includes accelerators, optical sensors (captures visual image of users environment in field of view),  GPS receiver (to keep track of users geographical location and movements)  Compass (determines geographical orientation of the user ) and  Gyroscope (determines rotational movement along with roll, yaw and pitch.
  19. 19. Processing. AR devices eventually should act like little computers, something modern smartphones already do. In the same manner, they require a CPU, a GPU, flash memory, RAM, Bluetooth/WiFi, a GPS, etc. to be able to measure speed, angle, direction, orientation in space, and so on.
  20. 20. Reflection/Display: Some AR devices have mirrors to assist human eyes to view virtual images. Some have an “array of small curved mirrors” and some have a double-sided mirror to reflect light to a camera and to a user’s eye. The goal of such reflection paths is to perform a proper image alignment.
  21. 21. Types of A.R 1.Marker-based AR 2.Position based AR. 3.Projection-based AR. 4.Superimposition-based AR.
  22. 22. 1.Marker-based AR  Some also call it image recognition  it requires a special visual object and a camera to scan  It may be anything, from a printed QR code to special signs.  The AR device also calculates the position and orientation of a marker to position the content, in some cases. Thus, a marker initiates digital animations for users to view, and so images in a magazine may turn into 3D models
  23. 23. Working Steps involved:  Marker detection  Calculation of the markerpose  Rendering with the pose
  24. 24. Mc lauren 570S app available in playstore APPLICATION OF MARKER BASED AUGMENTED REALITY
  25. 25. 2.Position –based AR  A.k.a. location-based, or position-based augmented reality  Utilizes a GPS, a compass, a gyroscope and an accelerometer to provide data based on user’s location.  This data then determines what AR content you find or get in a certain area.  With availability of smartphones this type of AR typically produces maps and directions, nearby businesses info.  Applications include events and information, business ads pop-ups, navigation support.
  26. 26. 3.Projection-based AR  Projecting synthetic light to physical surfaces, and in some cases allows to interact with it.  These are the holograms we have all seen in sci-fi movies like Star Wars  It detects user interaction with a projection by its alterations.
  27. 27. 4. Superimposition-based AR  Replaces the original view with an augmented, fully or partially. Object recognition plays a key role, without it the whole concept is simply impossible. We’ve all seen the example of superimposed augmented reality in IKEA Catalog app, that allows users to place virtual items of their furniture catalog in their rooms.
  28. 28.  Mobile devices  Special AR devices Augmented reality devices (smartphones and tablets) – the most available and best fit for AR mobile apps, ranging from pure gaming and entertainment to business analytics, sports and social networking. For processing and projection, AR devices and hardware, first of all, have requirements such as sensors, cameras, accelerometer, gyroscope, digital compass, GPS, CPU, displays, and things I’ve already mentioned. designed primarily and solely for augmented reality experiences. One example is head-up displays (HUD), sending data to a transparent display directly into user’s view. Originally introduced to train military fighters pilots, now such devices have applications in aviation, automotive industry, manufacturing, sports, etc.
  29. 29.  AR glasses (or smart glasses) – Google Glasses, Meta 2 Glasses, Laster See- Thru, Laforge AR eyewear, etc. These units are capable of displaying notifications from your smartphone, assisting assembly line workers, access content hands-free, etc. Google glasses Meta 2 glasses

  32. 32.  AR contact lenses (or smart lenses), taking Augmented Reality one step even farther. Manufacturers like Samsung and Sony have announced the development of AR lenses. Respectively, Samsung is working on lenses as accessory to smartphones, while Sony is designing lenses as separate AR devices (with features like taking photos or storing data).
  33. 33. Applications of A.R Gaming New AR games provide much better experiences to players, some even promote a more active outgoing way of life (Pockemon Go, Ingress).
  34. 34. Table zombies Ar lite
  35. 35. Education.  NEWSApple's Education-Focused iPad Event Pushes Augmented Reality Further into the Classroom  03/27/2018 11:00 PM  At Apple's education event in Chicago on Tuesday, augmented reality stood at the head of the class among the tech giant's new offerings for the classroom.  The company showcased a number of ARKit-enabled apps that promise to make learning more immersive. For example, the AR mode for Froggipedia, expected to launch on March 30 for $3.99 on the App Store, will allow students to view and dissect a virtual frog's anatomy. And a new update to the GeoGebra app brings ARKit support to math lessons.
