Applications of Augmented Reality

Although augmented reality has been around for years, it wasn’t until Android and iOS smartphones came equipped with GPS, camera and AR capability that augmented reality came into its own with the public. Augmented reality is technology that combines virtual reality with the real world in the form of live video imagery that is digitally enhanced with computer-generated graphics.

Handheld AR Equipment

The long list of AR software development kits for Android smartphones and Apple’s ARKit for its mobile devices give developers the tools they need to add AR elements to their apps.Want to view how a retailer’s virtual furniture looks in your room before you buy? There’ll soon be an AR app for that. Want to clean off your dining room table and populate it with your favorite action-adventure game locales and characters? You can.

AR Headsets

You may have heard of Microsoft’s HoloLens by now or Facebook’s Oculus VR headset. These high-end headsets were eagerly awaited by all, but only a lucky few could afford them. It wasn’t long before headsets were offered at a consumer price—the Meta 2 head-mounted display headset is a third the price of the HoloLens. Like most AR headsets, it operates while tethered to a PC—but it won’t be long before untethered headsets are available.

AR Applications

Early PC, smartphone and tablet applications for augmented reality focused on games, but the uses of AR are much broader. The military uses augmented reality to assist men and women as they make repairs in the field. Medical personnel use AR to prepare for surgeries. The possible commercial and educational applications are unlimited.

Military AR Uses

The Heads-Up Display (HUD) is the typical example of augmented reality when it comes to military applications of the technology. A transparent display is positioned directly in the fighter pilot’s view. Data typically displayed to the pilot includes altitude, airspeed and the horizon line in addition to other critical data. The term “heads-up” name applies because the pilot doesn’t have to look down at the aircraft’s instrumentation to get the data he needs.

Medical AR Uses

Medical students use AR technology to practice surgery in a controlled environment. Visualizations aid in explaining complex medical conditions to patients. Augmented reality can reduce the risk of an operation by giving the surgeon improved sensory perception. This technology can be combined with MRI or X-ray systems and bring everything into a single view for the surgeon.

AR Apps for Navigation

Navigation applications are possibly the most natural fit of augmented reality with our everyday lives. Enhanced GPS systems use augmented reality to make it easier to get from point A to point B. Using the smartphone’s camera in combination with the GPS, users see the selected route over the live view of what is in front of the car.

Sightseeing in Augmented Reality

There are a number of applications for augmented reality in the sightseeing and tourism industries. The ability to augment a live view of displays in a museum with facts and figures is a natural use of the technology.

Maintenance and Repair

Using a head-worn display, a mechanic making repairs to an engine can see superimposed imagery and information in his actual line of sight. The procedure might be presented in a box in the corner, and an image of the necessary tool can illustrate the exact motion the mechanic needs to perform.

AR Gaming Takes Off

With recent advances in computing power and technology, gaming applications in augmented reality are on the upswing. Head-worn systems are affordable now and computing power is more portable than ever. Before you can say “Pokemon Go,” you can jump into an AR game that works with your mobile device, superimposing mythical creatures over your everyday landscape.

Advertising and Promotion

The Layar Reality Browser is an application for iPhone and Android designed to show the world around you by displaying real time digital information in conjunction with the real world. It uses the camera on your mobile device to augment your reality.

Early Uses of AR

What would an NFL football game be without the yellow first down line painted on the field? Emmy award winning Sportvision introduced this augmented reality feature to football in 1998, and the game has never been the same.

Different Types of Augmented Reality

Augmented reality does not end with your smartphone. There are many more ways to enhance your perception of the world. However, it is important to understand that AR is not a monolithic technology. As is often the case, subtle (and sometimes not so subtle) differences in implementation can play a key role in how successful a technology is for a specific use case. Several categories of augmented reality technology exist, each with varying differences in their objectives and applicational use cases.

1.Marker Based Augmented Reality

Marker-based (also called Image Recognition) uses a camera and some type of visual marker, such as a QR/2D code, to produce a result only when the marker is sensed by a reader. Marker based applications use a camera on the device to distinguish a marker from any other real world object. Distinct, but simple patterns (such as a QR code) are used as the markers, because they can be easily recognized and do not require a lot of processing power to read. The position and orientation is also calculated, in which some type of content and/or information is then overlaid the marker.

2.Markerless Augmented Reality

As one of the most widely implemented applications of augmented reality, markerless (also called location-based, position-based, or GPS)AR, 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 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.

3.Projection Based Augmented Reality

Projection based AR  works by projecting artificial light onto real world surfaces. Projection based  applications allow for human interaction by sending light onto a real world surface and then sensing the human interaction (i.e. touch) of that projected light. Detecting the user’s interaction is done by differentiating between an expected (or known) projection and the altered projection (caused by the user’s interaction). Another interesting application of projection based augmented reality utilizes laser plasma technology to project a three-dimensional (3D) interactive hologram into mid-air.

4.Superimposition Based Augmented Reality

Superimposition based AR either partially or fully replaces the original view of an object with a newly augmented view of that same object. In superimposition based AR, 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 catalogue. By downloading an app and scanning selected pages in their printed or digital catalogue, users can place virtual ikea furniture in their own home with the help of augmented reality.

What is Augmented reality?

An enhanced version of reality where live direct or indirect views of physical real-world environments are augmented with superimposed computer-generated images over a user’s view of the real-world, thus enhancing one’s current perception of reality.The origin of the word augmented is augment, which means to add or enhance something. In the case of Augmented Reality (also called AR), graphics, sounds, and touch feedback are added into our natural world to create an enhanced user experience.

Augmented Reality (AR) may not be as exciting as a virtual reality roller coaster ride, but the technology is proving itself as a very useful tool in our everyday lives.From social media filters, to surgical procedures, AR is rapidly grow in popularity because it brings elements of the virtual world, into our real world, thus enhancing the things we see, hear, and feel. When compared to other reality technologies, augmented reality lies in the middle of the mixed reality spectrum; between the real world and the virtual world.

Augmented Reality vs Virtual Reality

Unlike virtual reality, which requires you to inhabit an entirely virtual environment, augmented reality uses your existing natural environment and simply overlays virtual information on top of it. As both virtual and real worlds harmoniously coexist, users of augmented reality experience a new and improved natural world where virtual information is used as a tool to provide assistance in everyday activities.

Applications of AR can be as simple as a text-notification or as complicated as an instruction on how to perform a life-threatening surgical procedure. They can highlight certain features, enhance understandings, and provide accessible and timely data. Cell phones apps and business applications by companies using augmented reality are a few of the many applications driving AR application development. The key point is that the information provided is highly topical and relevant to what you want you are doing.
