Chapter 1 1.2 Information Technology Literacy 1.2 Basic Online Terminologies and Concepts Applications of ICT  Communication ICT has changed the way people communicate :- People are better connected than in the past. Nowadays, we need not make phone call or send postal mails. ICT offers new means of communication that are cheaper and effective. ICT Communication is divided into 2 categories - Direct and Indirect Communication 2 3 4 Direct Communication Requires both ends - the sender and the recipient simultaneously. Examples :-  Real time Messenger - users can exchange message in real time  Voice over IP (VoIP) - users can make low cost voice calls through the Internet.  Video-conferencing - geographically isolated, users can hold meetings in real-time. 5 Indirect Communication Both sender and recipient do not require synchronisation or wait at the other end. The recipient can retrieve the content of the message at a later time. Examples :- WWW, Email, File sharing, Social networking and more. 6 Basic Online Terminologies 7 8 9 10 Bandwidth 11 Satellite Downlink And Uplink 12 Virtual Reality (VR) 13  https://youtu.be/i4Zt3JZejbg Image source : https://www.softwaretestinghelp.com/what-is-virtual-reality/ 14 APPLICATIONS OF VIRTUAL REALITY  Virtual Reality in the Military  Virtual Reality in Sport  Virtual Reality in Education  Virtual Reality in Media  Virtual Reality in Healthcare  Virtual Reality and Scientific  Virtual Reality in Entertainment Visualisation  Virtual Reality in Fashion  Virtual Reality in Telecommunications  Virtual Reality and Heritage  Virtual Reality in Construction  Virtual Reality in Business  Virtual Reality in Film  Virtual Reality in Engineering  Virtual Reality Programming languages VIRTUAL REALITY DEVICE  The most important piece of a virtual reality kit is the headset, a device like a thick pair of goggles that goes over your eyes.  The more expensive, higher quality headsets need to be connected to a computer to run apps and games, while some cheaper ones use a cell phone clipped to the front of the headset.  All headsets need to be used alongside a good quality pair of headphones, and there are other optional accessories from hand controllers to treadmills that are all designed to enhance your simulated experience of being in another world.  Hand controllers translate your real-world gestures into whatever game or application you’re using, although standard gaming joypads can also be used.  Major players in Virtual Reality include HTC Vive, Oculus Rift and PlayStation VR (PSVR) Image source : https://www.softwaretestinghelp.com/best-virtual-reality-headset/ https://www.youtube.com/watch?v=Z_0iFPRYAbI&t=83s 17 VIRTUAL REALITY IN THE MILITARY  Virtual reality has been adopted by the military – this includes all three services (army, navy and air force) – where it is used for training purposes.  This is particularly useful for training soldiers for combat situations or other dangerous settings where they have to learn how to react in an appropriate manner.  A virtual reality simulation enables them to do so but without the risk of death or a serious injury.  They can re-enact a particular scenario, for example engagement with an enemy in an environment in which they experience this but without the real world risks.  This has proven to be safer and less costly than traditional training methods.  These include:  Flight simulation  Battlefield simulation  Medic training (battlefield)  Vehicle simulation Virtual reality parachuting Virtual reality in the military  Virtual boot camp simulation 19 20 VIRTUAL REALITY IN HEALTHCARE  Surgical Theatre adapts MRIs, CT scans and other 2D medical imaging techniques into a 3D model.  Surgeons can then use VR to explore and interact with this 3D model to plan a surgery or update a patient on the process. 22 VIRTUAL REALITY IN EDUCATION  The Jackson School in Victoria, Australia has been using the Oculus Rift to help students with special needs and the Silesian University of Technology in Silesia Poland is doing therapeutic exercises with autistic students using virtual reality technology. 24 Tourism with VR https://immersionvr.co.uk/about-360vr/vr-for-tourism/ Image source : https://www.ediiie.com/tourism/ 25 Shopping using VR https://www.youtube.com/watch?v=e8Wt2lJ51_M https://virtualspeech.com/blog/vr-applications https://www.youtube.com/watch?v=in6JI-VuNyY&t=2s 26 ADVANTAGES & DISADVANTAGES OF VIRTUAL REALITY  A Real-time educational experience  VR is the way to explore places Advantages  VR Opens the world of Entertainment  Engagement and Interaction  Virtual Reality Isolates you in Real Life  VR Might Cause Eye Strain Disadvantages  Limited Educational Flexibility  Virtual Reality Can be Glitchy  VR is Addictive like drug  Expensive software and devices 28
