Virtual reality (VR) refers to a computer-generated simulation in which a person can interact within an artificial three-dimensional environment using electronic devices, such as special goggles with a screen or gloves fitted with sensors. In this simulated artificial environment, the user is able to have a realistic-feeling experience.
Some movies on Virtual Reality-
1) Ready Player 1( this one is great you must see it)
2)Tron Legacy(this is good)
3)Matrix
(See these movies to get a better understanding on the topic Virtual Reality)
Understanding Virtual Reality
The concept of virtual reality is built on the natural combination of two words: the virtual and the real. The former means "nearly" or "conceptually," which leads to an experience that is near-reality through the use of technology. Software creates and serves up virtual worlds that are experienced by users who wear hardware devices such as goggles, headphones, and special gloves. Together, the user can view and interact with the virtual world as if from within.
To understand virtual reality, let's draw a parallel with real-world observations. We understand our surroundings through our senses and the perception mechanisms of our body. Senses include taste, touch, smell, sight, and hearing, as well as spatial awareness and balance. The inputs gathered by these senses are processed by our brains to make interpretations of the objective environment around us. Virtual reality attempts to create an illusory environment that can be presented to our senses with artificial information, making our minds believe it is (almost) a reality.
Virtual Reality Use Cases
The simplest example of VR is a three dimensional (3D) movie. Using special 3D glasses, one gets the immersive experience of being a part of the movie with on-spot presence. The leaf falling from a tree appears to float right in front of the viewer, or the shot of a speeding car going over a cliff makes the viewer feel the chasm's depth and may give some viewers the feeling of falling. Essentially, the light and sound effects of a 3D movie make our vision and hearing senses believe that it's all happening right in front of us, though nothing exists in physical reality.
Technological advances have enabled further enhancement beyond standard 3D glasses. One can now find VR headsets to explore even more. Aided by computer systems, one can now play "real" tennis (or other sports) right in their living room by holding sensor-fitted racquets for playing within a computer-controlled game simulation. The VR headset that players wear on their eyes gives the illusion of being on a tennis court. They move and try to strike depending upon the speed and direction of the incoming ball and strike it with the sensor-fitted racquets. The accuracy of the shot is assessed by the game-controlling computer, which is shown within the VR game accordingly—showing whether the ball was hit too hard and went out of bounds or was hit too soft and was stopped by the net.
Other uses of this VR technology involve training and simulation. For example, those wanting to get a driver's license can get a first-hand experience of road driving using a VR setup that involves handling car parts like the steering wheel, brake, and accelerator. It offers the benefit of experience without the possibility of causing an accident, so students can develop a certain level of expertise in driving before actually being on the road.
Sellers of real estate can also use VR-aided walkthroughs of a home or apartment to give a feel for a property without actually having to physically be at the location with a potential buyer.
Other developing uses are training astronauts for space travel, exploring the intricacies of miniature objects, and allowing medical students to practice surgery on computer-generated subjects. Etc.....

India Likely to Ban China’s Huawei Over Security Concerns: Govt Officials
New Delhi:India is likely to block its mobile carriers from using telecom equipment made by China’s Huawei, two government officials said, under procurement rules due to come into force in June.
New Delhi is wary about awarding new technology business to Chinese firms both because of security fears and a desire to get Indian manufacturers to produce more telecoms equipment.
A US campaign to curb Huawei has triggered bans or limits on the use of its equipment around the world, but the situation in India has been amplified by strained relations between New Delhi and Beijing over their shared border.
India’s telecoms department said on Wednesday that after June 15, 2021 carriers can only buy certain types of equipment from government-approved “trusted sources” and said New Delhi could also create a “no procurement” blacklist. Huawei is likely to feature on this embargoed list, the two officials, who declined to be named, “We cannot prioritise economic gains if an investment poses national security risk,” one of the officials said.
The telecoms department, which did not comment on Thursday about Huawei, is yet to provide further details on the plans for trusted sources or a procurement blacklist. However, a third official, who also declined to be named, that ZTE Corp, another Chinese firm which has a smaller presence in India, could also be excluded.
Huawei and ZTE are under scrutiny for allegedly installing “backdoor” vulnerabilities to spy for the Chinese government. Both have denied the allegations and Huawei has previously it is ready to enter into a “no backdoor” deal with India to allay security concerns.
Huawei and ZTE did not immediately respond to requests for comment.
Two of India’s three big telecoms carriers, Bharti Airtel and Vodafone Idea, use Huawei gear. Any restriction on Huawei gear is likely to push up costs, industry analysts say. The Chinese firm’s equipment and network maintenance contracts are typically cheaper than European competitors such as Ericsson and Nokia, and there is limited availability of such gear in India.
India has begun to fast-track approvals of some of the more than 150 Chinese investment proposals worth over $2 billion it had put on hold after a June standoff between the two neighbours on the disputed Himalayan border. “We have started giving some approvals to investment proposals even from China, but we will not give any approvals in sectors like telecom infrastructure and financials,” a senior government official told .

The officials also said that India is unlikely to overturn last year’s ban on more than 100 Chinese mobile apps or allow Chinese companies to bid for stakes in state-run firms such as Air India and refiner Bharat Petroleum Corp Ltd.
India’s technology ministry did not respond to a request for comment on app bans.
India plans to raise $23.57 billion in the 12 months from April 1, 2021 by selling state-run companies.
India’s finance ministry did not respond to a request for comment.
The India-China border clash, the worst in nearly four decades, had soured already fragile relations, and “regaining trust would be a long road from here”,

Smartphones have become a staple item in everyday life, with80% ofUK consumers owning one in 2018. This number is sure to continue rising as the years go by, and smartphones become more affordable and therefore more accessible. They’re useful for just about everything; checking train times, snapping a quick photo, getting involved in the family group chat, or even – as the mobile was first intended for – making a phone call. All of this has resulted in the average adultspending 8 hours and 41 minutes on digital devices each day. For some individuals, however, this number is likely to be far greater. Many jobs require people to be sat in front of computer screens for 35-40 hours a week, even without your own personal use of a smartphone outside of work hours. While this is great for staying connected with people, arranging transportation, and getting work completed quickly and efficiently, what is the impact on our health?
What is blue light?
As the 2010s have been dubbed “the decade of the smartphone”, it’s no surprise that extensive research has been conducted in this area. One finding which seems to be mentioned everywhere is “blue light”. This is the light which is emitted from our phones, tablets and laptops and, sadly, it has been found to have negative effects on our eye health. Studies suggest that it has “a potential to lead to macular degeneration”, bypassing the pupil and cornea to beam directly into the retina. The blue light is thought to affect your central vision as it kills off photoreceptor cells in the retina. Unlike some other cells in your body, once these cells die, they cannot regenerate. This means that any damage done to them is permanent.
Mobile phone eye strain may cause dry eye and irritation, painful throbbing headaches
around the eye region, and even blurred vision. However, we use our phones differently to
computers. With computers, we may spend hours looking at a screen.
Smartphones Can Make Your Brain “Lazy”
Research shows this overreliance on your smartphone can lead to mental laziness. “If you give people the ability to store information remotely, outside of their brain, they become more dependent on that, which actually can have a negative effect on people's memory,”
