Augmented Reality

What Is Augmented Reality?

Augmented reality (AR) is a technology that superimposes a computer-generated image on a user’s view of the real world, creating a composite of the virtual and physical together in one frame. Augmented reality (AR) engages three of the user’s five senses – sight, hearing, and touch – creating a partially virtual experience. It doesn’t require goggles to create the experience (like Virtual Reality, or VR), meaning it’s not completely immersive.

Augmented reality (AR) is an enhanced version of the real physical world that is achieved through the use of digital visual elements, sound, or other sensory stimuli delivered via technology. It is a growing trend among companies involved in mobile computing and business applications in particular.

Benefits or advantages of Augmented Reality (AR)

Following are the benefits or advantages of Augmented Reality (AR):
➨The AR system is highly interactive in nature and operates simultaneously with real time environment.
➨It reduces line between real world and virtual world.
➨It enhances perceptions and interactions with the real world.
➨Due to its use in medical industry, life of patients have become safer. It helps in efficient diagnosis of diseases and in early detection of them.
➨It can be used by anyone as per applications.
➨It can save money by testing critical situations in order to confirm their success without actually implementing in real time. Once it is proven, it can be implemented in real world.
➨It can be used by military people without putting their life in danger by way of battle field simulation before the actual war. This will also help them in actual war to take critical decisions.
➨It can be applied to part of training programs as it makes things memorable and eye catching.

Drawbacks or disadvantages of Augmented Reality (AR)

Following are the drawbacks or disadvantages of Augmented Reality (AR):
➨It is expensive to develop the AR technology based projects and to maintain it. Moreover production of AR based devices is costly.
➨Lack of privacy is a concern in AR based applications.
➨In AR, people are missing out on important moments.
➨Low performance level is a concern which needs to be addressed during testing process.
➨It requires basic learning to effectively use AR compliant devices.

Examples of Augmented Reality

1. Snapchat

Snapchat is a popular American multimedia messaging app. It is full of trendy and catchy filters. Applications like Snapchat follow a basic procedure of imposing these filters on the user’s face. Firstly, the face is detected with the help of artificial intelligence.Then, these filters are digitally overlaid on the face of the user. This imposing of the filters look extremely real and original with the help of augmented reality and artificial intelligence.

2. Photography and Editing

There are a lot of videos on the internet that show permanent body tattoos to be moving and changing colors. These videos are created with the help of augmented reality. The AR enriched software is downloaded on a device and an algorithm is generated in such a way that when the device’s lens scans the tattoo, a moving and color-changing video gets supplemented over its surface. Therefore, it is not the tattoo changing color but it is the virtual image of the video that gets wrapped over the real object.

3. Hololens

Hololens technology is developed by Microsoft. It allows the users to operate their gadgets by looking at the screen levitating in front of them. In order to establish an easy user-machine interface, it employs features such as air tap, head tracking, gesture command, voice command, etc. This technology makes use of several “environment understanding” sensors, a depth camera, and spatial mapping. Hololens is an ideal example of augmented reality and holds a promising future.

4. Interior Decoration Apps 

We all want our home to be perfect, and we do everything to make it possible; however, making a permanent change such as changing the wall color, buying new furniture, etc. is risky because such huge changes can not be undone easily. This is why a lot of apps have been developed that allow us to virtually impose a picture over the physical objects to get an idea of how the change that we desire would look like after getting implemented. This provides us with the flexibility to try all available combinations and choose the best product. Asian paints, IKEA place, etc. are some examples of augmented reality-based interior decoration apps.

5. Google Glass 

Google Glass is a gadget that eliminates the need to continuously hold a cell phone in hand, in order to operate it. It allows us to access the phone virtually with the help of voice commands and gestures. Google Glass can be connected to the phone with the help of Wi-Fi or Bluetooth. It can perform various operations such as access the internet, manage phone calls and messages, take a picture, record a video, etc. This hands-free operation makes the mobile phone seem almost real, and it is possible only with the help of augmented reality.

6. Google Street View

Traditional maps have certain limitations when it comes to have detailed information about a place. On the other hand, digital maps can be accessed easily on mobile phones. Also, they provide us with a bonus feature of zoom in. Street view is an upgraded feature of google maps that allows us to move a step further in the direction of advancement. With the help of street view, the direction arrows and markings can be seen live in front of us. It makes use of augmented reality to superimpose the information over real-life objects. Thereby, making the maps easy, comfortable, and advanced to use.

7. Pitch Summary in Cricket

A Pitch map or pitch summary is used to trace the bowling length, whether it is short, long, or a yorker. It also displays the number of shots that went ‘on-side’ and ‘off-side.’ The distance and direction of boundaries are also represented with the help of a pitch map. Different colors are used to represent different aspects of the current over. These lines and marks are not present on the actual field, but they seem real because a digital augmentation is overlaid using AR technology.

8. Neurosurgery

Augmented Reality finds its prime application in the medical domain. During surgeries, neurosurgery to be precise, AR serves to be the perfect assisting partner as it highlights the blocked and damaged nerves digitally. This helps the doctors to easily operate on the affected nerves and avoid any possibility of human error.
