Is virtual reality the future of gaming?

The definition of virtual reality comes, naturally, from the definitions for both ‘virtual’ and ‘reality’. The definition of ‘virtual’ is near and reality is what we experience as human beings. So the term ‘virtual reality’ basically means ‘near-reality’. This could, of course, mean anything but it usually refers to a specific type of reality emulation.
Everything that we know about our reality comes by way of our senses. In other words, our entire experience of reality is simply a combination of sensory information and our brains sense-making mechanisms for that information. It stands to reason then, that if you can present your senses with made-up information; your perception of reality would also change in response to it. You would be presented with a version of reality that is n’t really there, but from your perspective it would be perceived as real. Something we would refer to as a virtual reality.

How is virtual reality achieved?

This is more difficult than it sounds, since our senses and brains are evolved to provide us with a finely synchronized and mediated experience. If anything is even a little off we can usually tell. These issues that divide convincing or enjoyable virtual reality experiences from jarring or unpleasant ones are partly technical and partly conceptual. Virtual reality technology needs to take our physiology into account. For example, the human visual field does not look like a video frame. We have (more or less) 180 degrees of vision and although you are not always consciously aware of your peripheral vision, if it were gone you’d notice. Similarly when what your eyes and the vestibular system in your ears tell you are in conflict it can cause motion sickness. Which is what happens to some people on boats or when they read while in a car.
If an implementation of virtual reality manages to get the combination of hardware, software and sensory synchronizes just right it achieves something known as a sense of presence. Where the subject really feels like they are present in that environment.

The virtual future of games

In less than a year, the three stand out consumer VR headsets – the Oculus Rift, the HTC Vive from Valve and Project Morpheus for Sony’s PS4 – will be out and in the hands of consumers. And with an array of games on the way, they could be immense fun.

“There’s an incredible feeling of being transported to another world that you just don’t get with any other type of gaming platform,” said Brian Allgeier, creative director of Insomniac Games’ Oculus Rift horror exclusive Edge of Nowhere. “Escapist fantasy is a big part of video games and VR has the power to transport players to amazing new worlds.”
However, VR is not likely to simply replicate the current array of games in a virtual form. Instead, certain genres are looking set to blossom on headsets in a way they have not done recently on consoles and PCs. Most notable of these is horror, thanks to the level of shock and emotion that a virtual experience offers.

Cam Newton is he the new face of NFL?

CHARLOTTE, N.C. -- Maybe it's time for Cam Newton to enter the presidential race. If he were 35 instead of 26, the Carolina Panthers quarterback could become the first dabbin' commander in chief. He could set a new standard for Oval Office style if he wore those yellow, Barocco, zebra-print Versace pants he sported for his team's flight to Super Bowl 50. If you look at the numbers, a Newton campaign is not as outlandish as you might think. Since the beginning of the season, his marketability metrics have skyrocketed as the Panthers (17-1) won games en route to Sunday's showdown with the Denver Broncos for the Lombardi Trophy. "He actually has better influential scores, the ability to change people's perceptions, than Donald Trump, [President] Obama and Hillary Clinton," said Peter Laatz, the executive vice president of Repucom, a global sports and entertainment research and consulting company. Repucom partners with The Marketing Arm on the Davie-Brown Index that measures the metrics of more than 3,800 athletes and celebrities. Newton has gone from No. 1,182 to No. 131 in the entire DBI database of influence. That puts him ahead of NBA star LeBron James, actors Matt Damon and Leonardo DiCaprio, and singer Blake Shelton. The U.S. population's awareness of who Newton is has gone from 38 percent in September to 52 percent in January. He still is not on par with New England'sTom Brady (88 percent as of this week) and Denver's Peyton Manning (85 percent), but the significant increase pushed Newton from 28th to ninth in the NFL. "Cam, interestingly, has metrics as powerful as previous quarterbacks that actually have won the Super Bowl," Laatz said. "If he wins the Super Bowl, he'll land on the top spot in most of the metrics in the NFL." One could argue Newton is becoming the face of the NFL. That Manning, who has set the standard in NFL marketing, will be the opposition Sunday at Levi's Stadium could represent a symbolic changing of the guard. According to Forbes, Manning is the NFL's top pitchman, with $12 million annually in endorsements from companies such as Papa John's Pizza, Nationwide Insurance and Gatorade. Newton's annual endorsement total will be $11 million, with $1 million in bonuses for helping Carolina reach the Super Bowl, said Carlos Fleming, senior vice president of talent management for IMG, which represents Newton. Fleming maintained his stance from prior to the season that Newton's portfolio -- Gatorade, Under Armour, Dannon, Belk and Drakkar Essence -- is second only to Manning's.

5 mobile phones you can buy under Rs.20,000

These are some interesting times for smartphone buyers, especially those who like to make a purchase based on hardware specifics. These are interesting times because buyers no longer have to burn a hole in their pocket to be able to afford these phones.

Here are 5  phones you can buy under Rs.20,000:

1. Lenovo Vibe S1

The Lenovo Vibe P1 is another great phone from Lenovo, it is offering an amazing package at a very good price. The first thing to talk about the phone is its massive 4900 mAh battery which gives a great battery backup and on top of it, its quick charging feature can charge the phone in just 60 minutes, claims the company. Moreover, you can use this phone to charge other phones also. When it comes to design, the phone looks beautiful and has got metallic (aluminium) sides and back and feels premium. It has also got a dedicated physical key on one side to switch to ‘Ultra Power Saver Mode’. The phone weighs 189 grams and is definitely on the heavier side but the big battery more than makes up for it. On the front it has got a physical home key below the screen which also acts as the fingerprint sensor. The fingerprint sensor works very well and gives you added security options and other features. The phone sports a 5.5 inches Full HD display with 401 ppi pixel density and comes protected with Corning Gorilla Glass 3. The display quality is very good. The Vibe P1 is powered by the Snapdragon 615 Octa Processor coupled with 2 GB RAM and delivers good performance. It features a 13 MP rear camera with PDAF (Phase Detect Auto Focus), zero shutter lag, Dual LED flash and a 5 MP front camera. The picture quality of both the cameras is good. It runs on the latest Android 5.1 Lollipop with Lenovo’s Vibe UI on top. Lenovo has also improved its Vibe UI, which now comes with more features and also includes the option to arrange your icons in an App drawer like Stock Android. The phone comes with Dual sim and 4G support on both sims. It has got 32 GB internal storage which is expandable upto 128 GB and, also supports USB OTG

2. OnePlus X

 The OnePlus X runs on the powerful and popular Quad-core Qualcomm Snapdragon 801 Processor clocked at 2.3 GHz and coupled with 3 GB RAM. It has great performance and you can use it for everything. It comes with Android v5.1.1 Lollipop out of the box with OnePlus’s own Oxygen OS running on top. The OnePlus OS which was designed after the company’s breakup with Cyanogen has near stock Android UI but comes with added features and customization options. It features a 13 MP rear camera with f/2.2 aperture and clicks good images, it can record Full HD videos. It has got an 8 MP front facing camera with f/2.4 aperture which also clicks good selfies. Great thing is, the phone clicks images very quickly without shutter lags, the built-in camera app comes with necessary features and is easy to use. The phone supports Dual Sim and 4G and comes with 16 GB internal storage which is expandable upto 128 GB with the help of a microSD card but sadly, it eats up the second sim slot. It is backed by a non-removable 2525 mAh battery. The phone is great but a fingerprint sensor would have made it an irresistible deal

3.Moto X Play:

The new Moto X Play sports a 5.5 inches 1080p Full HD display which turns out the pixel density of 403 ppi, the screen is protected with Corning Gorilla Glass 3 and the display quality is very good. Design wise, the phone looks beautiful & has got a good build quality. It also comes with water-repellent nano coating. It runs on the 1.7GHz Snapdragon 615 Octa-core CPU coupled with Adreno 405 GPU & 2 GB RAM & delivers decent performance but if you need a phone for gaming, it will be better to go with Zenfone 2. The phone has got a whooping 21 MP rear camera with f/2.0 aperture, Phase Detect Auto-Focus (PDAF) and Color Correlated Temperature (CCT) dual LED flash. The camera app comes with features like 4X digital zoom, auto HDR, burst mode, night mode, panorama, and Drag to focus & exposure. It can record 1080p HD videos at 30fps, it can also record slow motion videos and supports video stabilisation. All these features make Moto X Play the best camera smartphone under 20000 Rs. The phone also sports a 5MP front camera. It runs on the latest Android 5.1.1 Lollipop with stock Android UI, a good thing about Moto phones is that they continue to get latest Android updates faster than most flagship phones. Another great thing about the phone is its 3630 mAh battery which offers mixed usage up to 30 hours (claims the company) & supports quick charging. It comes in two storage variants with 16 GB & 32 GB internal storage, it is also expandable upto 128 GB. The phone supports dual sim and 4G. 

4. Xiaomi Mi4

It runs on the very popular and very powerful Snapdragon 801 Processor which was used in almost all the last generation flagship phones. To make the performance even greater it has got 3 GB RAM. So, there is no need to describe the performance, you yourself can imagine how fast and fabulously it will perform. It sports a 5 inches Full HD display which is also pretty good and bright. The things we should discuss in details is the camera performance of the phone. It has got the Sony IMX 214 CMOS sensor which is quite advanced. The camera quality is pretty good, it is capable of recording 4K videos, the Autofocus of the phone is pretty fast (0.3 Seconds) and decent and works quite well. The camera works quite well at night also, it has High Dynamic Flash which takes two photos one with flash and one without flash and then mixes the colours in both the photos so, the image gets natural colours. The 8 MP front camera is equally good. The battery life of the phone is good. Its design is simple but the metallic bezels gives it a premium and stylish touch. It runs on the custom Android skin of Xiaomi which is the MIUI V6 and is quite beautiful. The Infra-red blaster in the phone might be quite useful to control TV, AC,.Sadly, it is a single sim phone & doesn't come with 4G .

5. Sony Xperia C4 Dual:

The recently launched Sony Xperia C4 looks quite impressive. It houses the typically awesome design language of Sony but the USP of the phone is its 5 MP selfie camera which comes with soft LED flash. The flash can automatically adjust according to the lighting conditions whereas the front camera has a 25 mm wide-angle lens and Exmor R sensor which helps in reducing noise in the image. The front camera lets you click “PROselfies” with HDR and you can also shoot good selfie videos even in the night. The 13 MP rear camera also comes with Exmor RS sensor and is capable of taking high quality images. When it comes to performance, the Xperia C4 is powered by 1.7 GHz Octa Core Mediatek MT6752 Processor coupled with 2 GB RAM. The performance is quite good. The phone sports a 5.5 inches 1080 x 1920 pixels Full HD display with Sony Mobile BRAVIA Engine 2 and it is protected by Scratch-resistant glass. The display quality is very impressive with the 401 ppi pixel density. The phone runs on Android v5.0 (Lollipop) with Sony’s customised skin which is very beautiful. The phone supports 4G and dual sim. It comes with 16 GB internal storage which is expandable upto 128 GB. The 2600 mAh battery gives decent battery life to the phone.

Plastic grass could cover buildings to produce energy from wind

THE wind flowing over your roof is packed with energy, if you could only harness it. A new type of wind power generator carpets a surface with plastic strips that sway in the wind like grass, producing renewable energy where traditional windmills would be impractical.
The generator is made by fixing flexible strips of plastic to a board, so they stand upright like rows of dominoes. The strips have nanowires etched on one side and a coating of indium tin oxide (ITO) on the other. When the strips flail in the wind, the nanowires slap against the ITO surface of neighbouring strips. This temporary contact allows electrons to leap from one material to the other, creating a current through a phenomenon known as the triboelectric effect.
Covering a 300-square-metre rooftop with the strips “would be expected to deliver an electrical energy of 7.11 kW, which should mostly power a household,” says Weiqing Yang at Southwest Jiaotong University in Chengdu, China.
Yang worked on the project with Zhong Lin Wang’s group at the Georgia Institute of Technology in Atlanta. The goal was to tap energy not just from steady winds, but from the choppy gusts typical of built-up areas too. “Compared with a wind turbine, our triboelectric nanogenerator (TENG) is effective at harvesting the energy from natural wind blowing in any direction,” says Yang. He adds that the harvesting system is simple to make, and easy to scale to larger systems.
So far, the generator has only been tested in the lab, aiming an electric fan at a model rooftop covered with 60 strips. This generated enough electricity to light up 60 LEDs. The strips work at wind speeds as low as 21 kilometres per hour, but the most useful power was generated with direct wind at almost 100 km/h – or storm force 10.
That’s neither easily available nor desirable, says Fernando Galembeck, who investigates energy harvesting at the University of Campinas in São Paulo, Brazil. “Significant amounts of power are obtained but we are still far from installing these devices on our rooftops and building walls.”
Galembeck says that, as with any energy scavenging technique, energy storage will be crucial for the system’s success, allowing the variable amounts of power generated in gentle winds to be stored until needed.
Yang says they are seeking a storage solution, as well as working on integrating the nanogenerator with solar panels to boost output.
Galembeck also points out that indium tin oxide isn’t a suitable material, due to its poor mechanical properties, cost and toxicity. “The concept is highly promising but its realisation depends on shifting to other materials,” he says.

Will Li-Fi be the new Wi-Fi?

FLICKERING lights are annoying but they may have an upside. Visible light communication (VLC) uses rapid pulses of light to transmit information wirelessly. Now it may be ready to compete with conventional Wi-Fi.
“At the heart of this technology is a new generation of high-brightness light-emitting diodes,” says Harald Haasfrom the University of Edinburgh, UK. “Very simply, if the LED is on, you transmit a digital 1, if it’s off you transmit a 0,” Haas says. “They can be switched on and off very quickly, which gives nice opportunities for transmitting data.”
It is possible to encode data in the light by varying the rate at which the LEDs flicker on and off to give different strings of 1s and 0s. The LED intensity is modulated so rapidly that human eyes cannot notice, so the output appears constant.
UK researchers say they have achieved data transmission speeds of 10Gbit/s via "li-fi" - wireless internet connectivity using light.
The researchers used a micro-LED light bulb to transmit 3.5Gbit/s via each of the three primary colours - red, green, blue - that make up white light.
This means over 10Gbit/s is possible.
Li-fi is an emerging technology that could see specialised LED lights bulbs providing low-cost wireless internet connectivity almost everywhere.
High speed

The research, known as the ultra-parallel visible light communications project, is a joint venture between the universities of Edinburgh, St Andrews, Strathclyde, Oxford, and Cambridge, and funded by the Engineering and Physical Sciences Research Council.
The tiny micro-LED bulbs, developed by the University of Strathclyde, Glasgow, allow streams of light to be beamed in parallel, each multiplying the amount of data that can be transmitted at any one time.
"If you think of a shower head separating water out into parallel streams, that's how we can make light behave," said Prof Harald Haas, an expert in optical wireless communications at the University of Edinburgh and one of the project leaders.
Using a digital modulation technique called Orthogonal Frequency Divisional Multiplexing (OFDM), researchers enabled micro-LED light bulbs to handle millions of changes in light intensity per second, effectively behaving like an extremely fast on/off switch.
This allows large chunks of binary data - a series of ones and zeros - to be transmitted at high speed.
More sophisticated techniques could dramatically increase VLC data rates. Teams at the University of Oxford and the University of Edinburgh are focusing on parallel data transmission using arrays of LEDs, where each LED transmits a different data stream. Other groups are using mixtures of red, green and blue LEDs to alter the light’s frequency, with each frequency encoding a different data channel.
Li-Fi, as it has been dubbed, has already achieved blisteringly high speeds in the lab. Researchers at the Heinrich Hertz Institute in Berlin, Germany, have reached data rates of over 500 megabytes per second using a standardwhite-light LED. Haas has set up a spin-off firm to sell a consumer VLC transmitter that is due for launch next year. It is capable of transmitting data at 100 MB/s – faster than most UK broadband connections

This Bike Will Transform the Lives of Billions

Who knew a bike could do more than just promote health and wellness? ManojBhargaradid, and he seems to have a knack for generating long-lasting energy from seemingly simple sources. Bhagara is most well known for having amassed a fortune of over 4 billion US dollars from developing the 5 Hour Energy Shot and he is using that wealth (he has pledged over 90% if it, in fact!) to bring a different kind of energy into the homes of those that need it most. Perhaps inspired by the principle behind the energy shot, he has developed a bicycle that, from a mere hour of cycling, is capable of generating enough energy to power a house for an entire 24 hour period.
In a truly energy efficient manner, the bicycle requires one hour of steady cycling to put its simple engineering to task and it generates absolutely no pollution. The bike is built with a flywheel, similar to many stationary bikes. For those unfamiliar, the flywheel is a heavy, revolving when that is used to ‘increase a machine’s momentum and thereby provide greater stability or a of available power during interruptions in the delivery of power to the machine.’
Since the mechanism has the conservation of power built right into it, Manoj Bhargara hooked it up to a turbine generator that creates electricity as the user pedals the bike, which is stored in a battery. That battery will supply enough electricity to keep the home lit and basic appliances running for a full day.

From One Bike to Ten Thousand

The bike was developed at Stage 2 Innovation Lab, which he built in partnership with former Chrysler CEO, Tom LaSorda. The Lab is known as “the most well-funded playhouse for engineers that you could imagine” and is also the birthplace of a variety of other innovations aimed at tackling poverty, reducing the impact of climate change, and boosting access to potable water.[1] The bike can be made for around $100 USD. Bhargara recognizes that this is out of reach for many of the poorest people in need of it most, so he has committed to rolling out a pilot project in his native India, where he will issue 50 bikes to small villages in the province of Uttarakhard, where local labourers will manufacture them.
The design was purposefully simple, so “a bicycle repairman anywhere could fix it.”[2] While the innovation is a startlingly simple and effective response to the lack of electricity that plagues most of the developing world, it has been met with some criticism. Some purport that the device falls in a reactionary camp of development innovations, by keeping entire communities ‘off the grid’ rather than bringing more communities onto the grid. For this reason, many still question the ‘off the grid’ alternatives to energy access and may refuse it altogether as a steady source of power.
If the initiative proves to be as useful as he hopes, Bhargara will distribute 10,000 bicycles across the country next year. He envisions small villages sharing the bicycles; each family can procure a battery and can take turns cycling for an hour to power their home for the next day. He also doesn’t plan to entirely give them away. He is hoping spur local economic growth by having the bicycles manufactured locally and through incentivizing distributors with profits.

Billions in Change

Manoj Bhargara is part of an initiative called the Giving Pledge, which is led by the Bill and Melinda Gates Foundation. The initiative calls for the world’s wealthiest people to commit much of their fortunes to charitable development in areas such as poverty reduction, access to water, environmental conservation, climate change response and clean energy.

The bicycle, affectionately named the Free Electric, is only one of many innovations produced by the engineers at the Stage 2 Innovations Lab. Recently a documentary about this and the other health, water and energy innovations that are currently in research and development stages at the lab. The documentary is titled Billions in Change, and it features innovative techniques to make saltwater drinkable, to harness clean geothermal energy with graphene and eliminating our reliance on fossil fuels, and has even developed an auxiliary heart that pumps blood from the legs through to the core of the body.
