Okay, here is the converted markdown format from the attached document: # Unit 5: Cutting-edge Technologies ## Augmented Reality Hello! Let us learn about a new technology that has opened up amazing possibilities! We have already studied Virtual Reality in Grade 3. Before moving on to Augmented Reality, let us do a small activity. Identify these images and write the correct terms from the word bank given below. Virtual World, Controllers, VR Headset, Meta Quest 3 The image shows four pictures with labels below: * VR Headset * Virtual World * Controller * Meta Quest 3 Did you ever wish that your science textbook would show you what a heart actually looks like when its beating? **Augmented Reality (AR)** makes this possible. To augment something means to make it greater or better by adding to it. Now, let us understand what AR is in detail. ### WHAT IS AR? AR takes the real-world environment and adds virtual information to improve the experience. It is a technology that adds computer-generated elements, such as images, sounds, or text, to the real world, providing an enhanced view of reality. For example, imagine using your smartphone's camera to view your living room. There is nothing exciting about it, but with AR, this furniture appears as if it is actually there, allowing you to preview how it might look without physically placing it in your home. ### AR and VR **Augmented Reality** is when digital content is added to what you see in the real world, whereas **Virtual Reality** is like being inside a computer-generated world, often experienced by wearing special goggles. The image shows two people, one shopping with the aid of a screen showing AR data, and one using VR glasses and seeing a virtual reality world. * AR: Smart retail shopping * VR: Woman using VR glasses AR and its close cousin, Virtual Reality (VR), can be so much fun that sometimes people do not want to stop using them. This can be a bit of a problem, just like eating too many candies. When you use AR and VR too much, you might forget to enjoy the real world. ### Quick Check 1. What does AR stand for? * a. Alternative Reality * b. Advanced Reality * **c. Augmented Reality** * d. Animated Reality 2. Why is it important to find a balance when using AR and VR? * a. To make more friends * b. To save money * **c. To avoid forgetting the real world** * d. To become a computer expert ### Let's Meet **Ivan Sutherland** is an American computer scientist and Internet pioneer. He made the first special glasses that could show things that are not really there in 1968. He called it the 'Ultimate Display' and defined it as a window into a virtual world. But guess what? They did not call it 'augmented reality' until 1990 when another person named **Tom Caudell** gave it that name. It is important to find a balance and not let these fantastic technologies take up all our time. AR feels more real because it mixes digital stuff with what is really there. ### AR AS THE BRIDGE Imagine a world where the real and the imaginary come together. That is what Augmented Reality does. It acts like a bridge, connecting two different worlds—the world you live in and a world created by computers. In the real world, you can see friends, family, and everything around you. You can play in the park, explore nature, and learn new things at school. However, what if you want to add some extra fun or information to this real world? That is where AR steps in. With AR, you can see and learn amazing things. ### AR Adventure Do you like treasure hunts? AR makes them even more awesome! You can be walking in your neighbourhood and suddenly you spot a treasure chest on your phone's screen. It is not a real treasure, but it looks like it is right there in your park or even your bedroom. Remember the game Pokémon Go? It is a famous example of AR. You look at your phone and you see cute Pokémon characters in the real world around you. It is like they are hiding in your garden, on the street, or in the park. AR makes it feel like you are a part of a magical adventure. The image shows a phone screen with Pokemon GO game. AR is not just for fun, but it is also a fantastic tool for learning. In school, it can help you study history, explore ancient civilizations, and get up close to animals through your AR window. AR is like having a superpower to explore, learn, and have fun. It is like having your own magic portal to endless adventures! The image shows children watching a hologram of a dinosaur. ### THE FUTURE Imagine a future where the things you see on your phone screen become a part of your everyday world. This is where Augmented Reality is heading. It is like turning your regular world into an exciting place filled with new experiences. Let us check out some present and future applications of AR. ### Real-time Holography with AR Real-time 3D Holography can make giving virtual presentations easy with AR. The person can be projected through AR without have to be physically present. ### Entertainment There are various AR game applications that feature virtual pets. One such example is Dex: Your AR Dog Companion. ### Tourism Exploring new places might be amazing with AR. Tourists can point the AR application to any road sign or menu card and it can translate it to the language familiar to them. ### AR in Vehicles Imagine you are in a car and its windscreen can show you Augmented Reality. Then, if you ask for directions, arrows appear on the windscreen telling you where to turn. It can even display interesting information about the things you drive by though the driver should not be distracted. ### AR in Education Teachers can convey complex concepts using this powerful visual medium. They can bring real world context to subjects like History. You will be able to point your mobile phone, for example, at a bird or flower, and the phone will be able to tell you all about it. AR encourages practical learning. People are already using AR to explore museums and historical sites. Instead of just looking at paintings, AR is used to learn more about the artists and their work in an interactive way. Imagine learning about the solar system with AR. There are also NightSky apps of AR. You can point the app towards the sky in the night and it will label all the planets for you. The image shows a screen displaying planets and the solar system. ### AR in Healthcare Doctors are using AR during surgeries to see important information on their AR glasses, like a patient's vital signs or the location of sensitive blood vessels, without taking their eyes off the operation. The image shows a doctor with a patient's X-ray layered over their body. ### Quick Check 1. What is AR's goal? * a. Replace reality with VR * **b. Blend the real world with digital** * c. Create a virtual world * d. Improve driverless cars 2. How do doctors use Augmented Reality? * a. They spot road signs and objects * **b. They check a patient's vital signs** * c. They race virtually * d. They do not use AR ### AR Ads When you want to buy something, you typically go to a store, try the thing on, and then make your purchase. However, with the invention of AR, you can try them virtually from your home and buy them. ### Fact File Architects and builders use AR to visualize complex construction projects. They can see 3D models of buildings right on the construction site, making their work more accurate and efficient. The image shows a person using a tablet to look at a model of a construction project. Imagine trying on a pair of cool sneakers without going to a store, or seeing how furniture would look in your room before buying it. AR advertisements bring products to life and let you interact with them. So, the future of AR is all about making your world more incredible. It will help you learn, have fun, and even travel in new and exciting ways. With AR, your world will become a place where the real and the virtual are mixed together to create amazing adventures and experiences! ## Exercises **A. Mark a ✓ next to the right answer.** 1.
