Q11. What are the advantages of augmented reality?


The biggest advantage of Augmented Reality is that it creates unique digital experiences that blend the best of digital and physical worlds. Also, it does not need any special hardware or software to savor the experience. Mainstream smartphones and mobile apps are sufficient to experience Augmented Reality.

Q12. What is the scope of augmented reality?


  • Superimposing images, digital information and/or 3D models
  • Adding real-time directions
  • Inserting labels
  • Changing colors
  • Altering environment appearance via "filters" on Instagram, Snapchat, and other apps 

Q13. How augmented reality business cards work?


Augmented reality apps works with an image (best know as marker) that basically triggers the interaction with the user in the moment when the user points the marker with the device (phone, tablet etc.) camera. So they will need both the marker (your business card) and a mobile device with a web cam.

What you can do with AR cards is embed an AR marker in the card itself or adjust your logo to have a solid black border so that it could be used as a marker (this is currently a limitation in AR), and then this marker can become the trigger to show information to the user.

There is so much you can do with augmented reality from automatically showing addresses with interactive maps, to links for directly sending e-mails or phone calls, even an interactive portfolio. The possibilities are endless the limit is your imagination.

Q14. What is the Use of Augmented Reality in the Medical Field?


Augmented Reality(AR) is successful in offering numerous approaches which can handle complex medical situations of patients and classify the data of various types of surgery. With all this, the public can powerfully be aided with proper treatments which relax their minds and flush all the toxins out of their bodies. Such an example of AR in the medical field is medical imaging. In this, various types of diagnosis are performed by the surgeons, neurologists, or chemotherapists so that they may offer medical benefits to their patients by examining their body parts well. That body part could either be your brain, ear, heart, or lungs. You may wonder how such a diagnosis is made by medical professionals – they use AR applications for determining the end-to-end structure, margins, or shapes of the disease, like tumor or cancer. Later, those applications provide them with relevant insights after they delve into the bodies of their patients in an interactive three-dimensional augmented format. All this has potentially made intermediate surgeries or surgeries with low-survival rates not only safer but precise too. This is because a doctor or a chemotherapist can now view the patient’s insides for predicting the likelihood of a disease occurrence or to understand the condition of their patients accurately. Finally, those medical experts will be performing appropriate medical treatments in accordance with the data presented by AR applications in the form of graphs and images of the body parts of the admitted patients.

Q15. What are the Augmented Reality for Public Safety?


Public Safety simply means protecting the public from calamities, crimes, and other unknown dangers which can harm the public potentially. Whether you are working for a customer service sector or engaged with some drug enforcement agency, safety is something on which you can’t compromise. The app creators of KOVA corp have understood this and, as a result, launched an AR-based application, Silent Partner, which immediately and securely captures photos or videos of unexpected events like disasters from your smartphones. Later, you (or the public safety officials or police officials) can transmit those videos or pictures which are geotagged and retrieved easily anywhere. Besides, this application has a speech analysis functionality through which the voice content can be conveyed to investigators to safeguard the public. Another AR application (iOnRoad Augmented Driving Lite App) is for drivers, which uses GPS, sensors, and native cameras on their smartphones for detecting vehicles, so that drivers can be warned before the vehicle collides. Also, if, in case, the driver misses the collision notification, then an audio-visual warning pops to guide the drivers to apply brakes or reduce the speed of the car so that they may reach the predefined spots safely and on time. Such apps act as a powerful aid to responsible citizens involved with driving companies or police departments because their minds won’t think much about those plans which aren’t appropriate from the safety perspective of the public.

Q16. What are the Augmented Reality is Open for Travel 'N' Tourism?


Travel ‘N’ Tourism is all about managing the customers or travelers who will be exploring every nook of their destination with the accommodations arranged by a travel agent or a tour operator. However, if the travel services aren’t offered to the customers on time, it may decelerate the revenue growth generated by travel companies by leaps and bounds. Keeping this in mind, various agencies and hotels are using AR-based travel apps for helping their customers explore their destinations without compromising on the quality of transportation and food venues with interactive dish menus mapping the eating choices of travelers well. A few travel apps used by the agencies and hotels that showcase Augmented Reality are World Around Me, Smartify, ViewRanger, AR City. Whether you are trying harder to locate transportation, gas stations, ATMs, temples, or excited about scanning the brochures of agencies/ travel companies offering accommodations at pocket-friendly rates, any of these apps will help you identify what you are actually looking for! Thanks to these Augmented Reality-based applications which contain all the necessary details about the routes, method of transportation you may be familiar with, and some hotel accommodations booked after you narrowed your choices down. Now, you need not leave your beds and feel tense while learning more about the local attractions coming amidst your destinations.

Q17. What are the Augmented Reality is Mixing Up Well with the Entertainment Industry?


The 2021 Entertainment industry believes the fact that AR is a substantial marketing opportunity as the entertainment brands can mix their branded content well with the characters the audience likes the most. Those characters may either be revolutionary, analytical, idealistic, or humorous and may be selected upon the level of interest shown by the audience in real-time. There are many entertainment apps using the model of Augmented Reality Technology, but the famous ones are Snapchat, Google Lens, and Augment. Each of the apps can curatively augment the entertainment with its eye-gazing filters, stickers, lenses, and user-friendly emoticons. All these options can actively represent the moments you share with your families and friends. Besides, the experts of the 2021 entertainment industry believe in incorporating the chronological storylines of these entertainment applications more augmenting the reality of entertainment much more frequently. Either they are traveling to places or attending some comedy shows, it is feasible for them to produce content and mix it well with their marketing campaigns anytime, anywhere. What they need to keep in mind while creating the content is object orientation in real-time. If the same isn’t given proper attention, then it will create a negative impact on their motto with which they are spreading awareness about products whose qualities are yet to be discovered by the accounts of premium users.

Q18. What is the layer in augmented reality?


The augmented world is formed by detecting shapes and movements. This constitutes the physical layer. Beyond the physical layer of forms, there is the semantic layer which gives meaning to the things we see. The semantic layer involves training neural networks so machines can understand the world as we do
