VIRTUAL REALITY AND VIRTUAL IN ACADEMIC VIRTUAL REALITY AND VIRTUAL IN ACADEMIC
Definition What is virtual reality(VR)? A computer generated, immersive (or wide field),multi-sensory information program which tracks a user in real time.
Virtual Environment (VE) A computer generated world with which the user can interact Interaction can vary from looking around to interactively modifying the world.
History YearPerson(s) ResponsibleWhy it was important 1965Ivan SutherlandThe beginnings of VR 1977 Dan SandinDan Sandin, Richard Sayre and Thomas DefantiRichard Sayre Thomas Defanti Interaction through body movement 1982 Bonnie MacBird ( Writer) The first computer- generated movie 1983Myron KruegerFirst virtual environment 1984William GibsonWilliam Gibson (His assistant)The term 'Cyberspace' 1987Michael Piller (Writer)The Holodeck, idea of immersive VR 1992Stephen KingStephen King (Official Website)A look at the possible negative side of VR 1995Silicon GraphicsVirtual Reality Modeling Language 1999Larry and Andy Wachowski Virtual Reality movie grosses $750M worldwide
What is Immersive VR? 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.
Types Immersive Augmented Text-based Desktop (Window on a World) Video Mapping
Types 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.
Applications Architecture Training Medicine Engineering and Design E-Commerce Entertainment Manufacturing
Architecture 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.
Medicine 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.
Training 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...
Devices 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.
Binocular 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.
Cave Automatic Virtual Environment (CAVE) A room with projections on all walls, floor and ceiling The 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 mechanism ◦ Camera ◦ Device in hand
3D VIDEO Eyewear winner of a 2005 & 2006 Consumer Electronics Show Design Award. VR Price: $499.00
Virtual 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.VRML
Job Opportunities 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 deformations Parametric animation models (e.g. running) from video analysis Interaction between virtual humans and objects in the Augmented Reality framework.
Future 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 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 education Online education using the internet Cyber schools Virtual universities virtual program (Courses)
Instruction modes for virtual education - Are text based using HTML, Power Point or PDF documents Virtual classroom - Live teacher instruction and feed back online Virtual operating room - A space to learn the basic procedure before real-life one Hypertext courses - structured course materials. Hyperlinks connect text, multi media parts and exercise Video -based courses - Live face to face classroom courses students watch the video Audio based courses - like video but only the sound track of the lecturer Animated courses - Course material by animation
Cont…. Web- Supported textbook courses – Based on specific text books Peer-to-peer courses – Courses on -demand text books without a prepared curriculum new one emerged in 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.
Cont…. Communication and interaction Asynchronous instruction subsequent discussion Content delivered at the students pace Teacher acts as a guide Communication through discussion books and Students can interact with other students via notes, texts etc. Assignment submission electronically Collaborative communication outside occur through blogs, wikis multimedia tools etc.
Virtual learning environment Virtual 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 resources Similar terms used Learning management system (LMS) related concepts) Content management system (CMS) (only content) Learning content management system (LCMS) for corporate training overall infrastructure in a institution Managed learning environment (MLE) Learning support system (LSS) Online learning centre (OLC) Learning platform (LP) Computer –mediated communication (CMC) Online education Library management system (LMS) (now integrated library system ILS)
Components of VLE Course syllabus Administrative information about the course Notice board for current information Additional resources e.g. supplementary reading Self assessment Formal assessment Support for communications ( , twitter etc) Access rights for instructors, course staff and students Documentation and statistics Submissions by the students Provision for presentation with hyperlinks
Use of VLE by educational institution Use of VLE by educational institution Economize on the time of teaching staff and the cost of instruction Facilitate the presentation of online learning Provide students instruction in a flexible manner Provide instruction to the current generation Facilitate the networking of instruction between campuses and colleges. Provide for the reuse of common material provide automatic integration of the results of students learning in to campus information system.
Standards Shareable content object reference model For content –IMS global consortium Assessing VLE In 2003, Walker –Survey instrument to assess psychosocial learning environment of VLE instructor support student interaction and collaboration, personal relevance, authentic learning, active learning and student autonomy Distance education learning environment survey (DELES) -For students to assess systems available –on web –survey Virtual learning environment Sloodle,, 3D VLE called Edusim Umgumo-under development.
A virtual school or cyber school A virtual school or cyber school An institution that teaches courses entirely through online and accredited schools Agencies of accreditation ◦ Middle states association of schools & colleges ◦ North west association of accredited schools First school awarded by middle states association - Pennsylvania cyber charter school in Midland History –Descendants of correspondence schools (distance learning) Fees – free if state pays
Materials Materials Adobe systems products Jase products Macromedia products Carel products etc. Advantages and disadvantages ◦ Need not attend classes and travel ◦ Online study groups meat using Elluminate wimber etc.
Cont…. Cont…. No direct interaction hence lack of socialization Staying on task-difficult in home environment A virtual school library It is a PreK -12 library, a subunit of a virtual school. Watson and Ryar- Report 50% increase /annum in US Key component - Development of virtual schools library communication portals. System available - I Google page and an accompanying blog to deliver RRS (i.e. Z/US)- based library services to students and educators
Cont…. Cont…. A Virtual university It is one that provides higher education programs through electronic media, typically the Internet History – Distance education –the precursor Open university in UK –First one in 1960-concept of communications technology Wireless university – first discussed at the BBC by J.C. Stobbart UK with first idea of teleuniversity By Mid-Nineties OU –used the internet In 1970 Ivan Illich –concept of use of computer networks for learning In 1971 –George Kasey –Gave lecturers on philosophy of communications De-Design By 1972 –he established Media free times a periodical now web pages
Cont….. 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 Rajasingham In 1995 –OU – Catalonia –First virtual university
Teaching modes Two way audio –visual network Web –based Hypertext,videos, audios, s and video conferencing Quality –Questions remain about accreditation and the quality of assessment.
CONCLUSION CONCLUSION Everything 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.
