Augmented reality: closing the gap between the real and the virtual world

Augmented reality: closing the gap between the real and the virtual world

Augmented reality (AR) may not be as energizing as a virtual reality roller coaster ride.

However, it might end up being an exceptionally helpful apparatus in our regular day to day existences.

It holds this potential since it brings components of the virtual world, into this present reality, improving the things we see, hear, and feel.

Among the other reality innovations, augmented reality lies amidst the mixed reality spectrum, being between the real and virtual world. Computer games have been engaging us for over three decades, as far back as Pong was acquainted with arcades in the mid-1970s.

 PC designs have turned out to be substantially more advanced from that point forward, and game graphics are pushing the obstructions of photorealism. Presently, scientists and specialists are hauling illustrations out of your TV screen or PC show and coordinating them into certifiable conditions.

This new innovation, called augmented reality, obscures the line between what’s real and what’s computer-generated by improving what we see, hear, feel and smell.

On the spectrum between virtual reality, which creates immersive computer-generated environments and the real world, augmented reality is closer to the real world.

Augmented reality adds graphics, sounds, haptic feedback and smell to the natural world as it exists. Both computer games and cell phones are driving the advancement of augmented reality.

Everybody from travelers to soldiers, to somebody searching for the nearest metro stop would now be able to derive benefit from AR by the ability to put computer-generated graphics in their field of vision.

Augmented reality is changing the way we view the world — or at least the way its users see the world. Picture yourself walking or driving down the street. With augmented-reality displays, which will eventually look much like a normal pair of glasses, informative graphics will appear in your field of view, and audio will coincide with whatever you see.

These enhancements will be refreshed continually to reflect the movements of your head. Similar devices and applications already exist, particularly on smartphones like the iPhone.

A few classifications of augmented reality innovation exist, each with changing contrasts in their goals and applicational utilization.


Marker-based augmented reality (additionally called Image Recognition) utilizes a camera and some sort of visual marker, for example, a QR/2D code, to deliver an outcome just when the marker is detected by a code reader.

Marker-based applications utilize cameras with respect to the gadgets to recognize a marker from some other real-world objects.

Particular, however, basic examples, (for example, a QR code) are utilized as the markers, since they can be effortlessly perceived and don’t require a considerable measure of processing power to read them. The position and introduction are additionally computed, in which some kind of content or potentially, data is then overlaid the marker.


As one of the most widely implemented applications of augmented reality, markerless (also called location-based, position-based, or GPS) augmented reality, uses a GPS, digital compass, velocity meter, or accelerometer which is embedded in the device to provide data based on your location.

A strong force behind markerless augmented reality technology is the wide availability of smartphones and location detection features they provide. It is most commonly used for mapping directions, finding nearby businesses, and other location-centric mobile applications.


Projection-based augmented reality works by projecting artificial light onto genuine surfaces. Projection-based augmented reality applications take into account human cooperation by sending light onto a certifiable surface and after that detecting the human connection (i.e. touch) of that anticipated light.

Identifying the user’s communication is finished by separating between a normal (or known) projection and the adjusted projection (caused by the user’s connection).

Another intriguing utilization of projection-based augmented reality is using laser-plasma technology to extend a three-dimensional (3D) intelligent holograms into mid-air.


Superimposition based augmented reality either halfway or completely replaces the original view of an object with a newly augmented view of that same object.

In superimposition based augmented reality, object recognition plays a vital role because the application cannot replace the original view with an augmented one if it cannot determine what the object is. A strong consumer-facing example of superimposition based augmented reality could be found in the Ikea augmented reality furniture catalog.

By downloading an application and filtering selected pages in their printed or computerized inventory, clients can put virtual Ikea furniture in their own home with the assistance of augmented reality.


Augmented reality still has a few difficulties to overcome. For instance, GPS is just precise to within 30 feet (9 meters) and doesn’t function as well inside, albeit enhanced image recognition technology might have the capacity to help.

Individuals might not have any desire to depend on their mobile phones, which have little screens on which to superimpose data/information.

Therefore, wearable gadgets like SixthSense or augmented reality fit contact lenses and glasses will give users more convenient, broad perspectives of their general surroundings.

Screen land will never again be an issue. Sooner rather than later, you might have the capacity to play a real-time strategy game on your computer, or you can welcome a companion over, put on your AR glasses, and play on the laptop before you. There is such a mind-bending concept as an excess of data.

Similarly, as the “CrackBerry” phenomenon and Internet addiction are concerns, an overreliance on augmented reality could imply that individuals are passing up a major opportunity for what’s directly before them.

A few people may like to utilize their AR iPhone applications as opposed to an experienced tour guide, despite the fact that a tour guide might have the capacity to offer a level of association, an affair and an individual touch inaccessible in a PC program.

What’s more, there are times when a genuine plaque on a building is desirable over a virtual one, which would be open just by individuals with specific advancements.

There are additionally protection concerns. Picture acknowledgment programming combined with AR will soon, enable us to point our phones at individuals, even outsiders, and right away observe data from their Facebook, Twitter, Amazon, LinkedIn or other online profiles.

With the majority of these services, individuals energetically put data about themselves on the web, however, it might be an unwelcoming stun to meet somebody, just to have him knowing such a great deal about your life and foundation.

Notwithstanding these worries, envision the conceivable outcomes: you may learn things about the city you’ve lived in for quite a long time just by pointing your AR-empowered cellphone at a close-by stop or building.

On the off chance that you work in construction, you can save money on materials by utilizing virtual markers to assign where a pillar ought to go or which structural support to inspect.

Scientists working in shifts to amass a dinosaur skeleton could leave virtual “notes” to colleagues on the bones themselves, specialists could deliver virtual spray painting and specialists could overlay an advanced picture of a patient’s X-ray onto a mannequin for added realism.

Imagine that you stroll into your doctor’s office or dentist, just to discover that your doctor (or dental specialist) wearing an augmented reality headset.

In spite of the fact that it might look bizarre, this technology enables him to access past records, pictures, and other chronicled information progressively to talk about with you.

In a flash getting to this computerized data without the need to sign into a PC or check a records room, turns out to be a noteworthy advantage to human services experts.

Integration of augmented reality assisted systems with patient record management technologies is already highly desirable utility.

Data integrity and accessibility is a major benefit to this type of system, where record access becomes instantaneous and consistent across all professionals to the most current records, instructions, and policies.

The fate of an augmented reality is obviously splendid, even as it as of now has discovered its way into our cellphones and computer gaming frameworks.
