7What is Immersive VR? Virtual Reality A type of VR in which the user becomes immersed (deeply involved) in a virtual world. it is also a form of VR that uses computer related components.Virtual Reality
8Types Virtual Reality Immersive Augmented Text-based Video Mapping Desktop (Window on a World)Video MappingVirtual Reality
9Types of Non-immersive VR Text-based VR: when a reader of a certain text form a mental model of this virtual world in their head from the description of people , places and things.Augmented VR: the idea of taking what is real and adding to it in some way so that user obtains more information from their environment.Virtual Reality

11Architecture Virtual Reality An area in which virtual reality has tremendous potential is in architectural design. Already being created are architectural "walk-throughs" that allow designers and clients to examine homes and office buildings, inside and out, before they're built. With virtual reality, designers can interactively test a building before construction begins.Virtual Reality
12Medicine Virtual Reality researchers are using virtual reality technology to create 3-D ultrasound images to help doctors diagnose and treat congenital heart defects in children.The medical application of VR was stimulated initially by the need of medical staff to visualise complex medical data, particularly during surgery and for surgery planning, and for medical education and training.Virtual Reality
13Training Virtual Reality United States: The military used it as flight simulators to train pilots.National Aeronautics and Space Administration (NASA) use VR technology to construct a model of the Hubble Space Telescope (HST) .in September, 1993, approximately 100 members of the NASA HST flight team received over 200 hours of training using the VR...Virtual Reality
14Devices Virtual Reality Head Mounted Displays (HMD): Was the first device providing its wearer with an immersive experience. Evans and Sutherland demonstrated a head- mounted stereo display already in 1965.Virtual Reality
15Binocular Omni-Orientation Monitor (BOOM) BOOM is a head coupled stereoscopic display device. Screens and optical system are housed in a box that is attached to a multi-link arm.Virtual Reality
16Cave Automatic Virtual Environment (CAVE) A room with projections on all walls, floor and ceilingThe users wear shutter glasses to get a 3D view of the world.The users are able to move and control the environment with some kind of input mechanismCameraDevice in handVirtual Reality

18Virtual reality Modeling Language (VRML) Most exciting is the ongoing development of VRML on the World Wide Web. In addition to HTML (Hypertext Markup Language), that has become a standard authoring tool for the creation of home pages, VRML provides three-dimensional worlds with integrated hyperlinks on the Web. Home pages become home spaces.Virtual Reality
19Job Opportunities Virtual Reality The Swiss Federal Institute of Technology's (EPFL) Computer Graphics Lab has several openings for PhD students and Post Doctoral fellows in the areas of Computer Animation, Virtual Reality, and Computer Vision. Selected candidates will work on one or several of the following topics:Motion Control of virtual characters (kinematics, dynamics, and capture)Human body deformationsParametric animation models (e.g. running) from video analysisInteraction between virtual humans and objects in the Augmented Reality framework.Virtual Reality
20Future Virtual Reality In the past, computing power has doubled approximately every 18 months, a trend that is known as Moore’s Law. If this is the case then we should have a computer powerful enough to run immersive VR programs in our own homes by the year 2037.Virtual Reality
21Virtual education Characteristics of virtual education It refers to instruction in a learning environment where teacher and student are separated by time or space or both.Teacher provides course content through multimedia resources, internet and video conferencing. Students receive and communicate with the teacher via the same technologies.Characteristics of virtual educationOnline education using the internetCyber schoolsVirtual universitiesvirtual program (Courses)
22Instruction modes for virtual education - Are text based using HTML, Power Point or PDF documents Virtual classroom Live teacher instruction and feed backonlineVirtual operating room A space to learn the basic procedurebefore real-life oneHypertext courses structured course materials . Hyperlinksconnect text, multi media parts andexerciseVideo -based courses Live face to face classroom coursesstudents watch the videoAudio based courses like video but only the sound track ofthe lecturerAnimated courses Course material by animation
23Cont…. Web- Supported textbook courses – Based on specific text books Peer-to-peer courses – Courses on -demand textbooks without a preparedcurriculum new one emerged in2007.Social networking – Students can address a problem Teacher will act as guides and resources but it is up to the students to present, discuss etc.
24Cont…. Communication and interaction Asynchronous instruction subsequent discussionContent delivered at the students paceTeacher acts as a guideCommunication through discussion books andStudents can interact with other students via notes, texts etc.Assignment submission electronicallyCollaborative communication outside occur through blogs,wikis multimedia tools etc.
25Virtual learning environment Definition:It is an education system based on the web that models conventional real – world education by integrating a set of equivalent virtual concepts for tests, homework, classes classrooms and the like even museums and other external academic resourcesSimilar terms usedLearning management system (LMS) related concepts)Content management system (CMS) (only content)Learning content management system (LCMS) for corporate training overall infrastructurein a institutionManaged learning environment (MLE)Learning support system (LSS)Online learning centre (OLC)Learning platform (LP)Computer –mediated communication (CMC)Online educationLibrary management system (LMS)(now integrated library system ILS)
26Components of VLE Course syllabus Administrative information about the courseNotice board for current informationAdditional resources e.g. supplementary readingSelf assessmentFormal assessmentSupport for communications ( , twitter etc)Access rights for instructors, course staff and studentsDocumentation and statisticsSubmissions by the studentsProvision for presentation with hyperlinks
27Use of VLE by educational institution Economize on the time of teaching staff and the cost ofinstructionFacilitate the presentation of online learningProvide students instruction in a flexible mannerProvide instruction to the current generationFacilitate the networking of instruction betweencampuses and colleges.Provide for the reuse of common materialprovide automatic integration of the results of studentslearning in to campus information system.

32Cont…. A Virtual university It is one that provides higher education programs through electronic media, typically the InternetHistory – Distance education –the precursorOpen university in UK –First one in 1960-concept of communications technologyWireless university – first discussed at the BBC by J.C. StobbartUK with first idea of teleuniversityBy Mid-Nineties OU –used the internetIn 1970 Ivan Illich –concept of use of computer networks for learningIn 1971 –George Kasey –Gave lecturers on philosophy of communications De-DesignBy 1972 –he established Media free times a periodical now web pages
33Cont….. In 1992 –Virtual class lab moved on to the internet In A book “In search of the virtual class: education in an information society” by Tiffin and Lalita RajasinghamIn 1995 –OU – Catalonia –First virtual university
34Teaching modes Two way audio –visual network Web –based Hypertext ,videos, audios, s and video conferencingQuality –Questions remain about accreditationand the quality of assessment .
35CONCLUSIONEverything is going to be virtual in future . As we have to live and face the future gain more knowledge on virtual. In medical Fraternity virtual is replacing diagnostic procedure, treatment etc. Hence it is high time to introduce virtual in nursing curriculum .
