    Augmented Reality Became a Scientific Term

  • Here are the three components needed to

    make an augmented-reality system work:

    Head-mounted display

    Tracking and Orientation system

    Mobile computing power

    The components

  • Mobile

    computer

    Head mounted

    display

    Tracking and

    orientation

    system

  • Head-mounted Displays

    head-mounted displays (HMDs) will enable us

    to view graphics, text and virtual objects

    created by augmented-reality systems

  • A model of head mounted display

  • There are two basic types of HMDS:

    video see-through

    optical see-through

  • VIDEO SEE THROUGH

    Video see-through displays block out thewearer's surrounding environment, using smallvideo cameras attached to the outside of thegoggles to capture images.

    On the inside of the display, the video image isplayed in real-time and the graphics aresuperimposed on the video.

    One problem with the use of video cameras isthat there is more lag, meaning that there is adelay in image-adjustment when the viewermoves his or her head.

  • OPTICAL SEE-THROUGH

    Optical see-through displays is not fully realizedyet. It is supposed to consist of a ordinary-lookingpair of glasses that will have a light source on theside to project images on to the retina.

    Eg. Google Project Glasses

  • Tracking and Orientation

    An AR system needs to know two things

    precisely:

    where the user is located (Tracking)

    where he is looking. (Orientation)

  • Small Area Tracking

    For indoor application, where the movement of

    the user is short ranged we can make use of

    simpler tracking systems

    eg. Optoelectronics Tracking System which

    consists of user mounted optical sensors and

    infrared LEDs, embedded in special ceiling

    panels. The system uses the known location of

    the LEDs, the known geometry of the user-

    mounted optical sensors and a special

    algorithm to computer and report the user's

    position and orientation.

  • Large Area Tracking

    In case of out door applications, where the

    movement of user will be comparatively larger,

    his location with respect to his environments is

    tracked with the help of GPS RECIVERS which

    works in coordination with the GPS satellites.

  • ORIENTATION

    For orientation, an inertial/magnetic tracker rides

    on a headband above the AR glasses.

    This device detects head movements along with

    an electronic compass that establishes the

    direction of the viewer's gaze in relation to Earth's

    magnetic field.

  • Mobile Computing Power

    WEARABLE COMPUTERS

    Mobile computing can be accomplished with

    the help of a wearable computer. A wearable

    computer is a battery-powered computer system

    worn on the user's body (on a belt, backpack or

    vest). It is designed for mobile and predominantly

    hands-free operations, often incorporating head-

    mounted displays and speech input.

  • Wearable Computers

    Three important features of wearable computers are

    Constancy

    Augmentation

    Mediation

  • Constancy

    The computer runs continuously, and is

    always ready'' to interact with the user. It does not need to be opened up and turned

    on prior to use. The signal flow from human to

    computer, and computer to human runs

    continuously to provide a constant user--

    interface

  • Augmentation

    Traditional computing paradigms are based on the notion that computing is the primary task. Wearable computing, however, is based on the notion that computing is NOT the primary task.

    The assumption of wearable computing is that the user will be doing something else at the same time as doing the computing.

  • Mediation

    The wearable computer can encapsulate us. It

    doesn't necessarily need to completely enclose

    us, but the concept allows for a greater degree

    of encapsulation than traditional portable

    computers

  • Android Operating System

    An application on augmented reality

  • Features :

    1- Photography and video

    Google Glass has the ability to take photos and record 720p

    HD video. While video is recording, a recording light is

    displayed above the eye, which is unnoticeable to the

    wearer.

    Take picture : "ok, glass, take a picture.

    Record video : "ok, glass, record a video.

  • 2-location(sw-sb)

    GPS.

    Google Maps and Google Latitude.

    Give directions : "ok, glass, give directions

    to [place]."

  • 3-Other Google applications:

    3-1-Google Now

    Intelligent personal assistant(android).

    Display weather :

    "ok, glass, how is the weather in [location]?"ok, glass, do I need an umbrella today?

    Give flight details :

    "ok, glass, when does flight [flight number] departure from [airport]?"

  • 3-2-Searching

    Google Search and Google Goggles.

    Search : "ok, glass, google [search query].

    Search photos : "ok, glass, google photos of [search

    query].

    3-2-Translation

    Google Translate

    Translate : "ok, glass, say [text] in [language]."

  • 4-Send Message and Calling

    Bluetooth connection with android device or iphone.

    Send message:

    "ok, glass, send a message to [name].""ok, glass, send [name] that [message].""ok, glass, send [message] to [name].

    Calling:

    "ok, glass, call [name]."

  • To Do Its Function:

    1-hardware

    2-internet

    3-application(interconnection between hardware and internet)

    Explorer Program:

    updates to the Glass are planned after the program starts.

  • Project started : 2010

    Release date :

    Developers (US): early 2013

    Consumers: Q4 2013

    Price : 1,500 Dollars

  • Disadvantage Of AR :

    Profiling

    Spam

    Security and Privacy

    Interoperability (such as Wikitude AR and Layar AR browser)

    Games

    Openness

    Tablets and targets

    Physical danger

    Will it ever take off ?!!

  • Profiling

    The use of facial recognition technology, combined with geo-location and

    augmented data will lead to a seamless integration of our online and offline lives.

    As a result of these developments, a person walking around in the physical world

    will no longer just be a person, but will be their physical self along with a digital

    profile and other information that either the person itself or others make available

    online. Imagine walking into a social gathering and getting ignored by a bunch

    of people because you have self-identified yourself with a political or religious

    affiliation that they dont particularly care for. Or worse imagine being singled out for additional security screening at the airport because of it.

  • Spam

    Yes where there is a marketing opportunity, there will be spam, deceptive advertising techniques and social engineering tricks to dupe gullible consumers

    into paying for things they dont really need. If you think too many legitimate Internet companies (that are sensitive to your privacy concerns) are harvesting

    all the data you publicly share on the Internet, there are even more scammers

    out there doing the very same thing. Be ready to be tricked and duped by too

    good to be true augmented offers in the real world offers that will lure you in ways that unsolicited email from online pharmacies or belly-fat banner ads only

    wish they could.

  • Privacy and Security

    Nevertheless, all of this causes great concern for the privacy of its users and

    realistically Augmented Reality cannot come without its drawbacks. Here in the

    UK we are anything but anonymous and some people are unaware of how

    much of their personal information is accessible to complete strangers.

    Although it is not an issue for us in the UK at the moment because very few have

    began to use this service, it is a big thing in Japan. However, they have little

    problems with privacy as people remain very anonymous in Japan even though

    they have all the social media platforms that we do (if not more), the most you

    could get hold of is their email address. We seem to not have anything holding

    us back to uploading everything about ourselves; where we live, who we hang

    around with, and even what were doing at the weekend. They do not even have pictures of themselves up on their profiles in comparison to our 500 photos!

  • However, there are some measures to try and help us preserve our privacy. There

    have been some experiments with what is known as a badge that people can wear to passively manage dynamic privacy in environments where potentially sensitive information is streamed across real and virtual worlds. Such a device

    might be embedded in your mobile phone in the near future.

    The main problem with privacy for PROs is that there are no clear boundaries

    when it comes to accessing consumers personal information. The Data Protection Act (1998) is the only law that it supposed to protect our privacy yet

    this is vague and open to interpretation. When it was passed 13 years ago the

    internet had not become such a phenomenon.

  • Games

    The time difference between what you see and what really happen

    Have bad effect on young ability to separate the fiction from the reality. Three

    dimensional, real-time running augmented reality programs like "first person

    shooters" have been believed to increase teen aggression because they

    normalize violence.

  • Tablets and targets

    The challenge for many of the AR projects being shown and discussed at

    conferences like this is that to use them, you have to contort yourself around a

    tablet or smartphone, which becomes the window through which you see the

    augmented world. You might also have to print an AR "target" that your app uses

    as a beacon, over which it can display its imagery.

  • In some applications, using a tablet-and-target system works just fine. In an art

    gallery, for example, holding up a smartphone to view supporting media about a

    painting is not asking too much. And for commerce, the system can work as well: I

    used the Panasonic Viera AR Setup Simulator app to see how a flat-screen TV would

    look in my living room before I bought it (I got an LG instead, but that's a different

    story).

  • But in other applications, in particular for books and games, and for some

    gimmicky marketing apps, you have to drag out your phone, load a specific

    app, point the camera it at a particular target (a sign, a gameboard, a book),

    wait for the software to recognize what you're pointing at, and then keep the phone pointed at the target while you interact with the app.

  • Physical danger :

    Augmented Reality, like any mobile media technology presents

    some real physical safety issues. If you think mobile phones are

    currently a distraction while driving a car, think of an augmented

    windshield feeding you driving directions, along with more data

    about your surroundings than you may need. Or imagine crossing a

    busy street in an unfamiliar neighborhood, while simultaneously

    using an Augmented Reality interface to look for that hot new

    restaurant, checking out what people are tweeting about it and

    being bombarded with ads through it all.

  • Will it ever take off ?!!

    It is all very well and good if PROs start to include this media platform in their

    campaign tactics however it is not definite that it will take off in the UK like it has in

    Japan. It is important to remember that part of Japanese culture is to be tech

    savvy and it is not part of ours. But, maybe we are just being naive if we believe this

    will never take off and no one will ever use it here in the UK. It was only 20 years ago

    people would have laughed in your face if you said most households will have on

    average 3 computers/laptops by 2010. We can already see augmented reality

    being used by companies for promotional purposes.

  • Ford has just launched an augmented reality outdoor campaign to put its new C-Max model in the palm of consumers hands. It will project a virtual image of the car and allow passersby to have a go. It is claimed that it is the first outdoor

    campaign to use augmented reality in the UK and it undoubtedly wont be the last.
