Read the passage given below and answer the questions that follow:Comfortably enclosed in his Rome hotel room, the tourist switches on the console by his bed, and dons a special helmet like headset. He had to drop Paris from his tour programme- but that is no problem. He is about to ―take‖ a personalized tour of the city, walking under the arcade Triomphe, travelling up by lift to the top of the Eiffel Tower and even boating past Notre Dame on the Seine. If the fancy takes him, he can even zoom over the cathedral as if in a helicopter. Half an hour later, he emerges from his helmet-back into the real world of his hotel room.On board a hunter-killer submarine, the sonar operator is on red alert. An unidentified frigate has been detected and is closing in. The operator, again wearing special helmet-mounted display (HMD) and ―tactile feedback gloves‖, operates the sonar system, tracks the target, and computes a ―firing solution‖ for his weapon- torpedo. He can also ―pull up‖ his periscope and peer over the surface at the vessel closing in. His target ―destroyed‖, the operator removes the helmet, gloves and returns to the peaceful surroundings of the sub. There is no enemy anywhere around, indeed no alert of any kind.The two scenarios-all of them based on fact- are only a few examples where users have been transported to the new seamless wonder world of virtual reality (VR)-one of the hottest, most ubiquitous chunk of computer technology. Two seemingly divergent interests- the military and entertainment industries have been the most enthusiastic devotees of VR- both for very sensible reasons. Using suitable computer hardware, both are able to put together systems where the user can enter a 3-dimensional space, where he can be tricked into believing he is someplace else, and where his eyes, hands-his very brain seems to interact with a new virtual world.The applications are endless-limited only by one‘s imagination. Today teleconferencing - linking up individuals in different countries by TV has become old hat. The ―in‖ thing will be ―televirtuality‖, where participants on different continents can be brought together and will seem to hover in midairin the same room. It will allow two distant parties, for example to edit a document projected in the air, in front of them, make successive corrections which both can see in real time and to append their signatures to it.The Virtual Reality Team of Nottingham University, England, has exploited this new technological toy for a worthy educational task. Over 150 kids in townall physically challenged spastics- being trained to associated hand signs with familiar objects, now have the thrill of actually ― handling‖, even playing with such objects as balls, balloons and other toys.The entertainment industry has been quick to gallop into the VR arena. Pierce Brosnan and Jennny Wright appeared in a landmark film, ―The Lawnmower Man‖, where the audience was made to share their experience as they entered a virtual world. Plenty of special effects wizardry was expended in the process.These products for the geeky minded will inevitably proliferate, but this does not diminish the more serious applications. And none are more serious than defence technologists in the least half a dozen countries, for whom VR spells quantum jump in the realism of simulation. The cost of weapon systems and munitions has soared so rapidly that any simulator based on costly and hitherto esoteric technology like VR will always be cost effective.Not surprisingly, the U.S. Congress has recently approved $500 millions in the military research budget for projects, in just two fields- massively parallel programming and VR. And all three service wings have been swift to draw up plans to exploit the technology. Advanced technology submarine warfare displays for the navy; visually coupled aircraft systems simulators for the Air Force and for the Army, VR backed trainers, where the operator can fire a surface-to-air missile or drive a main battle tank across rough terrain in the teeth of enemy fire.Perhaps it will now be time enough to worry over something that is already bothering the medical profession in the west: going where no man has gone before, software and hardware-wise may be fine: what happens to the ―wetware‖ – the human brain-and are there any long term damages to the human user if he douses himself regularly in the unreal pleasures of VR?Answer the following by choosing the right option:1) Virtual Reality is a blessing to the defence technologists because a) it helps in training the defence personnel b) it‘s cheaper and safe c) it is non destructive d) all the above2) Virtual Reality is useful in training the spastic children in a) touching, feeling and playing with the toys b) learning to read and write c) helps them not to forget that they are spastics d) none of the above3) Read the passage carefully and choose the incorrect statement(s) i. Virtual Reality applications are unlimited ii. Tele Virtuality helps in bringing people closer physically in real time. iii. Virtual Reality is a trick played on people making them believe its all true. iv. Medical professionals have proved that the human brain would be damaged with the use of Virtual Reality a) i, iii and iv b) ii and iv c) i and iii d) i, ii and iv4) Man had not yet completely explored a) software b) hardware c) wetware d) all of the above5) The word ―ubiquitous‖ in the passage means a) omnipotent b) omniscient c) omnipresent d) chronological6) Entertainment industry has been using Virtual Reality for a) special effects b) 3D effects c) magic and wizardry d) all the above7) Choose the suitable quote about hard and software versus wetware.(a) Computers are incredibly fast, accurate and stupid: humans are incredibly slow, inaccurate and brilliant.: together they are powerful beyond imagination. Albert Einstein(b) The similarities between humans and computers are more numerous than the differences. P.A. Scott(c) To err is human but to really foul things up, you need a computer. Paul, R. Ehrlich(d) A Utopian future where we shed our bodies and upload our minds into computer and live for ever virtual, immortal, disembodied. Heaven for hackers.
