Augmented Reality and its roles in modern application era
Introduction:
Augmented reality is an interactive experience that combines the real world and computer-generated content. It can be also defined as a system that incorporated three basic features a combination of real and virtual worlds, real time interaction and accurate 3D registration of virtual and real objects.
Augmented reality is a digital medium that allows you to overlay virtual content into the physical world in a way that makes it seem like the content is physically there. Augment reality essentially allows us to merge the digital and physical worlds.
It all starts with AR enabled hardware such as a phone or glasses. Most importantly AR uses a system of cameras and in some devices also time of flight 3D depth sensors to see and understand the physical world around you.
The phone or glasses also map your surrounding environment and build a model of it using hardware sensors and specialized software. The research community has a word called SLAM which stands for simultaneous localization and mapping. This is what your phone or glasses do many times a second. They map your environment but also keep track of where you are in relation to it. Once mapping and localization are working well for a new environment an AR experience can begin.
Enhancement of DevOps toolchain with Integrated CI-CD based techniques
By placing the AR content, your phone or glasses readily place them in the virtual map of the environment. The virtual map however is invisible. So that’s the reason why it looks like the digital content is placed in the physical world. It is therefore really important that our virtual map is accurate and aligned with its physical counterpart.
In addition to mapping and localization, your AR device also senses other characteristics of the environment, for example the light intensity and colour temperature.
To make things as realistic as possible, our AR devices sense the conditions of our environment and project that onto our digital content. And that’s how AR works. It maps your environment and tracks your locations within it. By doing that, it allows you to place digital content into the physical world in a way that make you and those around you believe that it is actually there.
Augmented reality can be useful in different areas of technology. The areas in which the augmented reality is used includes:
Education
Augmented reality has a number of applications that can help improve the learning experience for students especially for more visual focused learners. One of the primary advantage of augmented reality is the ability for student to inspect a 3D hologram from many different angles. By moving around a virtual objector rotating it in space they can better examine and understand certain concepts.
This alone can revolutionize learning in topics like biology, anatomy, cosmology, geometry and more. It can even revolutionize how AR also enables students to benefit from at home experiential learning. Students can run scientific and mathematical simulations in 3D space and view the results from every angle. For example, students can see how certain medications affect various organs in the human body. And they can adjust various physical conditions on a virtual planet to see how those conditions affect its ability to support life. This kind of learning is more likely to be remembered and understood by students compared to other methods.
Appliances, Furniture and other Tangible products
There are over a dozen smartphone apps that make this possible. With AR, customers click on a product and instantly see it overlaid wherever they point their mobile device. That means customers can see how appliances and furniture look in their homes. In this scenario, customers could quickly change types of appliances and furniture colours, sizes and many other things. This is excellent for visualizing room arrangements and colour matching before making a purchase.
Shopify AR is an example of a tool that already allows customers to view products in natural environment before buying them. This is to ensure that the products are fit for the purpose intended.
Clothing and fashion
Augmented reality stimulates in person shopping experience online by allowing customers to see how a product might look on them. For example customers can see how virtual versions of jackets, footwear, jewellery, makeup and sunglasses look on them. Some people call this virtual fitting room technology. Smart phones smart glasses and other handheld and wearable devices will provide the bulk of these experiences. Smart mirrors are another way to use augmented reality to facilitate these types of experiences.
JARVIS – Like Virtual Assistance
A company called Mojo is currently developing AR lenses with micro LED displays that place information inside the wearer’s eyes. Its first priority is to help people struggling with poor vision by providing better contrast or the ability to zoom in on objects.
It could also enhance our sight in low light conditions or serve as a teleprompter for speaking events. Eventually, AR lenses and AR glasses could be used to augment the world around us and even facilitate virtual assistance with the help of sophisticated artificial intelligence.
The creation of the Metaverse
The combination of augmented reality virtual reality, artificial intelligence 5G networks and other technologies make the open metaverse possible. The metaverse refers to a convergence of physical augmented and virtual reality in a shared online space. The metaverse is the next step in the internet’s evolution. You can think of the metaverse as a 3D or 4D version of the current 2D internet.
Outdoor and Indoor Navigation
AR could make it easier to navigate in outdoor and indoor environments. For indoors a line could overlay the ground and guide you toward a destination in a large airport, an airport parking lot, a large mall, an office building, a college campus and so on.
For outdoors instead of typing in an address into your map software, you will be able to point to a location and the directions will pop up automatically. And you will follow an AR created trial on the ground perhaps with considerations to physical obstacles that might be in the way. Additionally you could point to an object such as a building and receive information about it without even knowing what it is for.
Healthcare
There are mainly three big roles augmented reality will play in the future of healthcare.
Consumer education
Augmented reality can help patients understand the benefits and risks of certain medications and procedures by providing visual demonstrations and simulations.
Assisting Doctors
Augmented reality can help doctors by creating simulations of how certain procedures should be done and it can help medical students by offering a very intuitive representation of the human body.
Medication Scales
The completion among drug makers is strong and even slightest advantage can lead to huge sales. If a sales person is trying to gain the attention of doctors towards a new medication, they can use virtual simulation to demonstrate the positive effects of the drug.
Automotive Industry
Augmented reality head up displays can help driver’s process information that enhances their view of road. This type of display can make drivers aware of potential hazards occurring ahead of them. They can also make it easier to navigate than traditional map software by the customized visuals that are tailored to the terrain. Additionally augmented reality can be used for automotive marketing.
