Editor's Notes
- In this session of Intro to ar and vr I will be talking about the basics of Augmented and Virtual Reality
- We will be talking about Click Reality? What it is? And the crux of today’s session Click What is Augmented, Virtual, Mixed and Extended Reality?
- Let us begin the session by answering a very simple but intuitive question. What is Reality? According to simple.wikipedia, Click Reality means anything that exists. Click An event that has actually happened, or a thing which really exists is said to have "reality." Something close to reality is realistic. Reality is the state of things as they are, rather than as they may appear or might be imagined. Click The concept of reality gave rise to a technology called as “IMMERSIVE TECHNOLOGY”
- Which leads us to the question of Click What is Immersive Technology? Click Immersive technologies create distinct experiences by merging the physical world with a digital or simulated reality. Click Augmented reality (AR) and virtual reality (VR) are two principal types of immersive technologies. These technologies share many of the same qualities. However, Click AR blends computer-generated information onto the user’s real environment, while VR uses computer-generated information to provide a full sense of immersion. But let me take a step back, I am getting ahead of myself. Let me first share something very interesting with you all.
- How did the concept of reality gain so much boost even in the late 1950s? It started in the year 1957. Immersive technology for recreational purposes was brought to the fore with the invention of Sensorama. Click This cinematic experience, developed by Morton Heilig, placed the viewer in a “sensory” theater that included speakers, fans, smell generators and a vibrating chair to immerse the viewer in the movie. Click The goal of the sensorama was to replicate reality for each of the senses of sight, hearing, smell touch and taste. This was the pioneering sep toward modern day Augmented and Virtual Reality. Let me talk a bit about Augmented Reality.
- So I'm going to start by discussing Click What is Augmented Reality Click The types of Augmented Reality Click And lastly a video demonstrating AR
- So what exactly is Augmented Reality? Click Augmented Reality (AR) is a type of Immersive Technology where digital images are presented on top of the real world. This means that users who leverage AR aren’t completely shut off from the world. Click Instead, AR extends and enhances their reality.
- A great example of AR is Snapchat Filters. With Snapchat Filters you can overlay digital images of a puppy, cat, movie star, etc. onto your face. You can even move your phone around and see clouds around you or stars. Another familiar example is Pokemon Go where users can walk around their neighborhood with their mobile phones and find Pokemon that are overlaid on the environment around the user. Another well known example is the overlay of stats on the ground while broadcasting sports.
- Briefly, there are 4 types of Augmented Reality Marker-Based Marker-Less Projection-Based Superimposition-Based Marker Based AR is tied to a specific physical image pattern marker in a real-world environment to superimpose the virtual 3D object, text, or animation on top of it. The cameras continuously scan the input and put a mark for image pattern recognition to create its geometry. Markerless AR refers to the software application that does not require any camera to put a mark for image pattern recognition. Markerless AR places virtual 3D objects in the real-life environment by examining the features present in the real-time data. Projection Based AR is a method of delivering digital data within a stationary context as projection-based AR focuses on rendering virtual 3D objects within or on a user’s physical space. The user can freely move around the environment within a specified zone where the fixed projector and a camera for tracking are placed. Superimposition Base AR is used either for partial or full replacement of the original view of an object with an updated augmented view of that object for the human eye. Superimposition AR provides multiple views of a target object with the option of showing extra relevant information on that object.
- Let us take a look at Augmented Reality in Action
- Now that we know briefly about what Augmented Reality is Click Let us quickly talk about what virtual reality is Click Its types Click And watch a video demonstrating the application of virtual reality
- Click Virtual Reality (VR) is the use of computer technology to create a simulated environment. Unlike traditional user interfaces, VR places the user inside an experience. Instead of viewing a screen in front of them, users are immersed and able to interact with 3D worlds. By simulating as many senses as possible, such as vision, hearing, touch, even smell, the computer is transformed into a gatekeeper to this artificial world. Click Virtual Reality’s most immediately-recognizable component is the head-mounted display (HMD). Human beings are visual creatures, and display technology is often the single biggest difference between immersive Virtual Reality systems and traditional user interfaces. Click Major players in Virtual Reality include HTC Vive, Oculus Rift and PlayStation VR (PSVR)
- In non-immersive VR, only a subset of a user’s senses is stimulated, allowing the user to maintain awareness of the physical environment outside of the virtual reality. For example, the HP Reverb Pro headset allows designers to create 3D models. Click Semi-immersive VR leverages more senses than non-immersive VR, but still does not take advantage of all senses. For example, flight simulation allows pilots to learn how to fly different aircrafts through realistic displays that simulate different in-flight experiences. Click Finally, fully-immersive VR stimulates all of the user’s senses. For example, Infinadeck has created an omnichannel treadmill that allows users to move within a virtual environment.
- Let us take a look at Augmented Reality in Action
- MR brings together real world and digital elements. In mixed reality, you interact with and manipulate both physical and virtual items and environments, using next-generation sensing and imaging technologies. Mixed Reality allows you to see and immerse yourself in the world around you even as you interact with a virtual environment using your own hands—all without ever removing your headset. It provides the ability to have one foot (or hand) in the real world, and the other in an imaginary place, breaking down basic concepts between real and imaginary, offering an experience that can change the way you game and work today. Although mixed reality is still in the early stages, it is already being used in many industries for educational purposes. Click For example, aircraft manufacturers are using MR as a cost-effective way to train repair technicians. Instead of pulling an engine out of an aircraft to conduct a training session, technicians wearing special headsets can view a holographic image of an engine and use gesture, gaze and voice user interface (VUI) commands to interact with the hologram, changing perspectives and extracting meaningful information, layer by layer. So what is the difference between AR VR and MR? The fundamental difference is that VR users have an entirely virtual experience, while virtual elements are added to AR users’ real-world experience. MR users can interact with these added virtual elements during their real-world experiences.
- Click XR is an emerging umbrella term for all the immersive technologies. The ones we already have today—augmented reality (AR), virtual reality (VR), and mixed reality (MR) plus those that are still to be created. All immersive technologies extend the reality we experience by either blending the virtual and “real” worlds or by creating a fully immersive experience. Extended Reality is the term used when referring to the use of a combination of real and virtual environments via wearables and computer technology generated human-machine interactions. Click It is also defined as a term that enhances existing technologies such as AR, MR, and VR; however, in actuality, MR, VR, and AR form the three pillars of XR. With this, I have come to an end of my presentation and I would like to thank each and everyone of you for your kind attention!
