Augmented reality is a technology that superimposes computer-generated information on the user's view of the real world. This information may be visual or audio.
It uses sensors like gyroscopes, accelerometers, cameras, and GPS to collect data about the environment. It then processes this information to display virtual 3D models and animations.
Definition
If you've ever used Snapchat filters or a home decor app to see what furniture would look like in your living room, you've experienced augmented reality (AR). AR is one of the pillars of Industry 4.0, the fourth industrial revolution transforming business in surprising and innovative ways.
The technology overlays computer-generated virtual content into a user's view of the real world, using sensors in smartphones or smartglasses to recognize 2D or 3D images. It can also be used to add digital text or graphics onto physical objects.
Some of the earliest examples of AR were heads-up displays (HUDs) in military aircraft or tanks, which superimposed instrument panel-type data over the cockpit view. Faster computer processors made it possible to combine AR with video and photographic displays, creating what is now commonly referred to as augmented reality.
Many companies are Augmented reality definition now leveraging AR to boost productivity and drive operational efficiencies. For example, AccuVein uses AR to superimpose the location of a patient's veins, and Boeing used AR to cut the time it takes for trainees to assemble an aircraft wing by 35%.
History
Augmented reality is one of the most innovative developments in digital technology. It has brought many benefits to different industries including retail, manufacturing, logistics and more.
While it would be tempting to trace the history of AR all the way back to 370 BC, when Socrates first considered writing as an emerging technology, a more appropriate starting point is 1957 when cinematographer Morton Heilig invented Sensorama. This device featured a head-mounted display system that presented simple wireframe drawings overlaid on the real physical world.
The late 1990s marked a turning point for AR as it began to transition from research labs and prototypes into practical real-world applications. A basic form of the technology involved a camera-equipped device, such as a smartphone or tablet, that was loaded with AR software. When the device was pointed at a specific object or location, the program recognized it using computer vision technology and displayed relevant information superimposed over the object.
Types
Augmented reality is a type of technology that superimposes digital information over the real world, blending virtual and physical environments. It has potential to improve human lives through UX design, reducing risks and making tasks easier for people. AR can also help solve important global problems and create new jobs.
There are a few different types of AR. One is marker-based AR, which uses a physical object to trigger a digital experience. Another is projection-based AR, which uses projectors to overlay 3D images onto surfaces. This type of AR doesn’t create fully immersive experiences, but it can be used for things like holograms at events and movies.
The third kind of AR is location-based, which ties augmented reality to specific locations. This type of AR relies on positioning data gathered by a device’s camera, GPS, digital compass, and accelerometer to display relevant information and objects. This kind of AR has a wide range of applications, from shopping to navigation systems for cars.
Applications
Using AR technology, users can view virtual information over their real-world environment and interact with the content in 3D. Augmented reality applications range from entertainment and gaming (Niantic’s Pokemon Go mobile game, downloaded 750 million times, is a good example) to navigation and tools.
Many companies are using AR to improve maintenance and operational efficiency, support continuous production and reduce employee downtime by allowing technicians to access detailed machine information on demand. They can also use it to train and practice on equipment without risk, and even connect with experts remotely for help if they encounter an issue.
AR is used in healthcare to teach medical students how to perform procedures and increase empathy by giving them immersive, realistic simulations that mimic human movements. Beauty brand Sephora uses AR to allow customers to try out different eye, lips and cheek products or colors on their digital faces. In sports, AR can help coaches better analyze a play or even track the trajectory of a ball as it moves through airspace.
