Augmented Reality – An Immersive Projection
Virtual reality points our senses completely into the world concentrated only in the digital realm. Whereas augmented reality takes us into the real world of the present real. It also projects digital imagery and sounds much into it. Both Augmented and Virtual Reality comes under a continuum of mediated reality. while computer system enables our perspicuity of reality versus the real world.
Augmented reality refers to most sophisticated, better interactive. It spatially aware implementation of the concept as like digital objects such as 3D models or 3D videos are projected onto our view of reality.
How Augmented Reality Works
The type of augmented reality you come across make use of a range of sensing units (including a camera), computer components and a display device to make the illusion of virtual objects in the real world.
In general, the device points particular target. This can be anything out of the circle. Usually, it is a 2D image printed in something resembles the poster of a movie. If the augmented reality (AR) application points its target via the camera or any other means. It starts processing the image and augments it in a way with pictures and sound effects. Say, if you see the movie poster spring to life and play a trailer for the movie. As long as your looks at the poster through the window of your display you can see augmented reality instead of the old plain vanilla reality.
With the help of algorithms and other sensory units such as accelerometers and gyroscopes. The device can make the augmented parts aligned with the image of the real world.
Make use of a smartphone or tablet computer as a “magic window” to enter into the augmented world. Which is one of the ways to relay this digital info into our eyes? But there are many other options to achieve this.
Projection mapping is nothing but digital imagery projected directly onto physical objects. It can be used to quite striking effect. For example, consider Dyadic Mano-a-Mano uses projectors and Microsoft Kinect sensing units to provide the user with 3D digital imagery projected directly into the environment. The user doesn’t want to wear any equipment or use any devices for the visual attire. Interaction with this system is highly natural and amazing.
Projection Mapping For The AR
Projection mapping as an augmented reality method has a wide range of applications. But it prefers a controlled and mapped space for its better functioning. One of the amazing technique is that it make use of head mounted systems. That is most likely to supplant smartphone augmented reality as a common implementation outside of the lab.
Actually, this is the place where virtual and augmented reality begins to converge. As there are any satisfactory explanations why head mounted systems used in both technologies cannot be cross-functional. Of course, head mounted systems make use of smartphones to work with something called as a camera “pass-through”. In other terms, even though you can’t see anything other than the screen of the head mounted display (HMD). But you can make use of rear facing camera of the phone to have a look at outside world. This feature gives us a way to use for augmented reality without the use of any external handheld device. This method leaves one feature a bit way out from the experience. Since the camera’s perspective and lack of depth perception don’t sync compared to what our eyes see.
By making the system used in Google Glass and Microsoft Hololens it is somewhat possible to resolve this issue. And both of the systems is making use of “prism projector”. The eyes of the user look out at the world is not in constrained mode, but the digital imagery is projected into the prism projection system that sits between the eye and the real world. It makes an illusion as if those objects are really present over there, sitting on a table or hanging on the wall.
There are many ways to obtain the goal of augmented reality. But the conclusion what you can see will be a combination of digital information bound with the analog world, which enables many applications. Let’s have an eye over such applications
Applications of Augmented Reality
Augmented reality has a wide range of applications in several industrial and technical field. Since the use of smart devices is in the most advanced and developed stage. The rise in the use of such devices and overall computing technology developments gave a new platform in the mainstream consumer space.
Education and gaming are the two areas. Where we have pointed a lot of commercial innovations and development in augmented reality.
Education and gaming are the two biggest mainstream video game consoles. Both have included augmented reality capabilities for the last two generations. These games are in the form of the Kinect (for the Xbox) and Playstation Eye or Camera (for the Playstation 3 and 4 respectively). Here you face both the camera and the screen and are more like augmented reality mirrors. Where you see yourself “in” the game and you can interact with game characters present in the same room as you.
Mobile augmented reality games are not rare at all. They can be found on smartphones, tablets and handheld consoles such as the Nintendo 3DS and Playstation Vita.
The potential for augmented reality in education has being implemented in fields such as medicine where students can benefit from living and real 3D models. It is possible to make use of existing learning material (like pages from a textbook) as targets for augmented reality. While viewed through the lens of a smartphone you can see that picture of an engine animate in an engineering textbook or a working 3D model of a beating heart that you can walk around of rotating by hand and can understand it very well.
In medical practice, augmented reality can project information directly into the body of patients. For example, the Vein viewer system projects a real-time image of infrared vein scans directly into the patient’s skin. Creating the impression that the skin is transparent. This allows the clinician to view the veins directly.
Military use cases are also a picture. The soldiers wearing heads-up displays (HUDs) can view the information tagged onto objects in the real world. Radar information, orders or any other relevant sensor data from devices on the network that can provide it. Enemy and friendly positions can be figured out easily. Augmented reality clearly has a bright future in military applications.
Mobile phones especially the iPhone which uses augmented reality apps allows you to view computer generated images. This has been superimposed over the real world images. With the help of an app you to find a restaurant. An example of this works by displaying restaurant signs/logos as you move in a particular direction.
Another useful type of app is a golf GPRS system which helps golfers around a course. It displays yardages for each of the 18 holes. Shows where the hazards are. e.g. bunkers and advice and gives suggestions to improve your game. If you are golfer then this app will appeal to you immensely. Look for the Golfscape Augmented Reality Rangefinder from the Apple play store.
Check Magic Leap Augmented Reality Prototype, a placeholder derived from an internal model naming theme used by the corporate.
Augmented reality is used in marketing as well as advertising for enhancing certain aspects of a product in order to make it more attractive which will raise their sales.
Augmented reality is likely to grow up in its way. Surely it comes to our daily lives more and more in the 21st century. Once wearable computers become common it won’t be strange to see people interacting with and reacting to things that are not there from your perspective level. Technologies like augmented reality will give us a new way to work with computing devices. A concerning division between digital and analog reality is likely to change. Just hop onto your smartphone’s app store and search for “AR” apps where you get a plenty to try and many of them free.
