AUGMENTED, VIRTUAL, AND MIXED REALITY CHAPTER OUTLINE  Augmented Reality  Virtual Reality  Mixed Reality  Difference between AR, VR, and MR  Architecture of augmented reality systems  Application areas of augmented reality I. Augmented Reality Augmented Reality  Augmented reality (AR) is a form of emerging technology that allows users to overlay computer-generated content in the real world. AR refers to a live view of a physical real-world environment whose elements are merged with augmented computer-generated images creating a mixed reality. Augmented Reality  The augmentation is typically done in real-time and in semantic context with environmental elements. By using the latest AR techniques and technologies, the information about the surrounding real world becomes interactive and digitally usable. Through this augmented vision, a user can digitally interact with and adjust information about their surrounding environment. Augmented Reality II. Virtual Reality Virtual Reality  VR is fully immersive, which tricks your senses into thinking you’re in a different environment or world apart from the real world. Using a head- mounted display (HMD) or headset, you’ll experience a computer-generated world of imagery and sounds in which you can manipulate objects and move around using haptic controllers while tethered to a console or PC. Virtual Reality Virtual Reality  Using VR devices such as HTC Vive, Oculus Rift or Google Cardboard, users can be transported into a number of real-world and imagined environments.  The most advanced VR experiences even provide freedom of movement – users can move in a digital environment and hear sounds. Moreover, special hand controllers can be used to enhance VR experiences. III. Mixed Reality Mixed Reality  Mixed Reality (MR), sometimes referred to as hybrid reality, is the merging of real and virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real-time. It means placing new imagery within a real space in such a way that the new imagery is able to interact, to an extent, with what is real in the physical world we know Mixed Reality  For example, with MR, you can play a virtual video game, grab your real- world water bottle, and smack an imaginary character from the game with the bottle. Imagination and reality have never been so intermingled.  The key characteristic of MR is that the synthetic content and the real-world content are able to react to each other in real-time. Mixed Reality  For example, with MR, you can play a virtual video game, grab your real- world water bottle, and smack an imaginary character from the game with the bottle.

Differences Differences of VR, AR, and MR  One of the most obvious differences among augmented reality, virtual reality, and mixed reality is the hardware requirements and also VR is content which is 100% digital and can be enjoyed in a fully immersive environment, AR overlays digital content on top of the real-world. and MR is a digital overlay that allows interactive virtual elements to integrate and interact with the real-world environment. Numerous augmented reality apps and games can run on almost every smartphone on the market. Differences of VR, AR, and MR  On the other hand, virtual reality programs require specialized VR headsets, noise-canceling headphones, cameras to track room space and boundaries, and sometimes even motion capture technology.  Mixed reality hardware is still emerging and hasn’t quite broken into the mainstream consumer market, most likely due to the price. Differences of VR, AR, and MR V. Architecture of AR Systems Architecture of AR Systems 1. Infrastructure Tracker Unit  The Infrastructure Tracker Unit was responsible for collecting data from the real world 2. Processing Unit  It mixes the virtual content with the real content and sent the result to the Video Out module of the Visual Unit. Some designs used a Video In, to acquire required data for the Infrastructure Tracker Unit. 3. Visual Unit  Video see-through: It uses a Head-Mounted Display (HMD) that employs a video-mixing and displays the merged images on a closed-view HMD.  Optical see-through: It uses an HMD that employs optical combiners to merge the images within an open-view HMD. VI. Application of AR Systems In Education  AR can be used to enhance content and instruction within the traditional classroom, supplement instruction in the special education classroom, extend content into the world outside the classroom, and be combined with other technologies to enrich their individual applications. In Education  Affordable learning materials  Interactive lessons  Higher engagement  Higher retention  Boost intellectual curiousity In Medicine  Augmented reality has the potential to play a big role in improving the healthcare industry. Only a few years since the first implementations of augmented reality in medicine, it has already filled an important place in doctors’ and nurses’ routine, as well as patients’ lives.  This new technology is enhancing medicine and healthcare towards more safety and efficiency In Medicine  Describing symptoms  Nursing care  Surgery  Ultrasound  Diabetes Management  Navigation In Medicine  Reduce the risks associated with minimally invasive surgery.  Better informed decisions about the right treatment and illness prevention.  Make procedures more tolerable.  Better aftercare  Medical training and education.  Assistance in medical procedures and routine tasks. In Entertainment  Games  Music  TV  eSports  Theater THANK YOU!
