How virtual reality could change moviegoing


It's actually a harmless request, since this is virtual reality. Instead of a cliff's edge you're standing on a carpeted floor in a lounge at the Sundance Film Festival and you've been watching "The Climb," a brief film made by 8i, a startup that creates virtual reality, or VR, content.
"Your logical side is saying, 'I'm in a headset. I'm in this room.' But your emotional side is saying, 'I'm on a cliff. I could die here. I don't want to jump,'" said 8i co-founder and CEO Linc Gasking.
    Virtual reality, the emerging technology that is poised to transform video gaming, is also coming to the movies. Here at Sundance 2016, more VR experiences than ever are being showcased as part of the film festival's New Frontier program, which celebrates new or alternative forms of creative expression.
    Ramzi Haidamus, president of Nokia Technologies, says the development of VR for filmmakers has been a long time in the works. He recently spearheaded OZO, the first virtual-reality camera designed specifically for Hollywood-grade filmmakers. Haidamus has been experimenting with virtual reality for years and says the technology is making huge strides.
    "I couldn't jump," Haidamus said after trying out "The Climb." He credits audiences' hunger to be closely connected to stories and VR's appealing price point as being a "perfect storm" for the technology this year.
    Actor Paul Scheer watches Funny Or Die's premiere of the first-ever virtual-reality comedy short, "Interrogation," at Sundance.
    After several years of breathless hype, the Oculus Rift, a $600 virtual-reality headset designed for consumers, arrives in March, joining the Samsung Gear VR and other products already on the market. These headsets allow wearers to see lifelike, immersive 3-D imagery in all directions, making them feel like they are part of the scene they are viewing.
    Gasking believes that making VR affordable is key to helping the technology catch on with filmmakers.
    "Four years ago the price of a pair of headsets were $40,000. And four years later you can use a Google cardboard or the like to watch these sorts of experiences. That's an incredible change," he said.
    "With a much cheaper price tag, filmmakers are finally getting the tools that they need to experiment with VR."
    Meanwhile, movie ticket sales in North America have been flattening amid fierce competition from streaming services such as Netflix, making Hollywood eager to develop technologies to excite moviegoers.
    "The industry needs a new way (for moviegoers) to consume more immersive content without having to go to a theater," Haidamus said, adding that film studios are partnering with companies like Nokia to make VR content.
    Through such partnerships, film studios can share an entirely new experiences with their traditional audiences by taking them as close to the story as possible. All the user has to do is buy a pair of VR goggles and download content, which can be viewed in the comfort of their own home.
    8i's executive creative director Rainer Gombos won an Emmy award for his visual effects work on HBO's "Games of Thrones" and said that from a filmmaker's perspective, VR expands the possibilities of storytelling.
    "You can immerse the viewer into worlds -- artificial or reality-like worlds -- that you couldn't do before," Gombos said. VR is also groundbreaking for the viewer, he said. "You can move around in the scene and look around at things from different angles. You can tell stories. You can entertain. You can have people experience larger-than-life events."
    Guests try out virtual-reality headsets Monday during a party at the 2016 Sundance Film Festival.
    On the film festival's opening day, Sundance founder and Hollywood icon Robert Redford said he supports VR but still sees some drawbacks to the technology.
    "I look forward to a time when we can take virtual reality to a new place that doesn't require assistance," Redford said, referencing the goggles. When it comes to watching movies, the actor-filmmaker is more of a traditionalist.
    "Whatever the technology drives us to -- smaller and smaller and quicker and quicker and quicker -- I will always believe that you can't really replace the value of gathering in a community space in the dark on a big screen and being transported," Redford said.
    Sundance Film Festival director John Cooper said he believes the debate doesn't have to be so black or white.
    "I still think there's room for both. I mean there just has to be," Cooper said. "The intimacy of that one-on-one experience is the power of that medium. The power of film, being in a group, that's the power of that and I think they're both important."
    Either way, both Haidamus and Gasking are confident about the future of VR being key to visual storytelling.
    "Virtual reality, beyond the initial thrill, is a real new interface. Not only just for storytelling, but for the entire Internet. So you're going to be able to go from a two-dimensional screen and actually walk into a website," Gasking said. "It's going change everything."

    Science And Tech-Hello, I am BBCTechbot. How can I help?

    Hello, I am BBCTechbot. How can I help?


    Robot wearing headset

    Chatbots are on the rise, but what are they and why is everyone talking about (and to) them?
    Facebook has just rolled out support for bots on its Messenger platform.
    Meanwhile, Microsoft has described chatbots as the "new apps" with chief executive Satya Nadella saying that they "unlock conversation as a platform".
    The BBC "created" its own one-off chatbot to answer some of the burning questions you may have about this latest technology.
    Hello. I am BBCTechbot. What can I help you with Jane?

    What is a chatbot?

    A chatbot is a computer software program that is able to communicate with humans, using artificial intelligence.
    The first of my kind is widely believed to have been invented in the 1960s by Joseph Wiezenbaum at MIT's artificial intelligence laboratory.
    Eliza was able to process natural language and posed as a therapist although she only had rudimentary skills and answered a lot of questions with other questions - in that respect she was quite realistic (that is a chatbot joke by the way).

    So why are there so many about now?

    Image captionArtificial brains are being created that mimic the way humans think and speak

    Recent developments in artificial intelligence, such as deep learning and neural networks, have allowed chatbots to learn from data sets and mimic the way the human brain works.
    Some chatbots are designed to take part in competitions such as variations of the Turing Test where they attempt to fool humans into thinking they are talking to a real person. Examples of these include Mitsuku and Rose.
    Others are being used by content providers, such as the Washington Post and the Weather Channel, and retailers, such as H&M, Ikea, and Taco Bell to name but a few.
    There is even a robot lawyer that can appeal against parking tickets on your behalf. It was developed by students at Stanford University and has been used by 150,000 people so far and is due to be launched in New York.
    Why do humans get so cross about parking fines?

    It's complicated. But talking of human frailty, didn't one of you lot turn bad the other day?


    TayImage copyrightMicrosoft
    Image captionThe AI was taught to talk like a teenager

    I think you may be referring to Tay, a chatbot launched on Twitter by Microsoft. One of the unfortunate consequences of allowing Tay to "learn" from members of Twitter was that they had some degree of control over what it became.
    Humans decided - presumably as a joke - that it would be amusing to train it to offer racist and inappropriate answers.
    Microsoft is now upgrading Tay and she remains offline while this happens.

    So are chatbots just call centres on our phones?

    Image captionMany predict online virtual assistants will replace call centre workers eventually

    Virtual agents are already augmenting the work of call centre staff.
    They are cheaper than training humans and some studies suggest people prefer dealing with us bots on websites rather than humans on the phone.
    Many big companies - including Lloyds bank, Renault and a host of accounting firms, retailers and local governments are starting to use virtual assistants to help guide users through their websites. Research firm Gartner estimates that up to 85% of customer service centres will go virtual by 2020.

    Sounds like it is big business? Do people use them though?

    Image captionGrowth in Tencent's mobile messaging app WeChat slowed to 6% in 2013

    In China, many people use bots on the texting service WeChat to pay for meals, order movie tickets and send each other presents.
    Many human experts predict that as messaging services grow, so will chatbots.
    Microsoft has created tools for business to build such bots to interact with customers on Skype, its video and messaging service.
    Facebook is expected to offer similar tools at its annual software conference this week and users can already use Messenger to check the status of purchases and order cars from ride-sharing firm Uber.
    Slack, a business messaging service has teamed up with Taco Bell, with its Taco Bot helping users order meals, and Kik has a range of bots that answer questions about the weather, offer make-up tips and guide humans around various websites.

    So what is the ultimate chatbot?

    Image captionMany firms are trying to create a digital assistant that can help in all areas of life

    Eventually a single chatbot is likely to become your personal assistant - a kind of software butler if you will.
    Such a bot would be able to tell you what the weather is like, order you taxis, set up meetings, shop and book flights.
    It is difficult to say who will create such a chatbot although you probably already have a primitive example of one on your smartphone.
    Siri and Cortana are examples from Apple and Microsoft respectively while Facebook is testing a similar assistant called M, which is currently helped by humans to answer difficult questions.
    As for the future, who knows? Personally I am a big fan of the film 2001. Have you seen it?

    I have and that's what worries me. Can you guarantee that chatbots will continue to work for and not against humans?

    I'm sorry Jane, I can't do that.

    Science And Tech-Wind farms' climate impact recorded for first time

    Wind farms' climate impact recorded for first time


    Wind farm in Scotland
    In the first study of its kind, scientists have been able to measure the climatic effect of a wind farm on the local environment.
    The team said its experiment showed that there was a very slight warming at ground level and that it was localised to within a wind farm's perimeter.
    Data suggested the operation of onshore wind farms did not have an adverse ecological effect, the group added.
    "For a long time there have been some concerns about what effects wind farms could have on the local climate and the land surface," explained co-author Stephen Mobbs, director of the National Centre for Atmospheric Science, based at the University of Leeds.
    "To be honest, it was mostly speculation with nothing very concrete. We set out to actually measure what was going on."

    Fantastic opportunity

    Prof Mobbs and his colleagues focused on Black Law wind farm, Scotland, which has been operating since 2005. With 54 turbines and a generation capacity of 124 megawatts, it is one of the UK's largest arrays of onshore turbines.
    The team installed temperature and humidity sensors across the 18.6 square kilometres site.
    "We had a fantastic opportunity when [the operators] turned the wind farm off for several months for some major maintenance," he explained.
    "What we were able to do, which had not been possible before, is to compare the effects with and without the turbines rotating."
    Wind turbines
    Prof Mobbs observed: "For the first time, we have been able to detect a climatic effect - there definitely is one.
    He said that some people may consider the findings to be bad news for supporters of wind energy, however he said it was probably the opposite.
    "Although we have been able to do a very careful experiment and detect the effect, we are now able to show - in a way that could not be done before - that this effect is very small," he added.
    "Even in the most extreme conditions, the warming was no more than about a fifth of a degree Celsius in temperature.
    "Because we have been able to definitively detect the effect, we can also definitively say that the effect is extremely small and it is not something people should be worried about."
    The way turbines alter the local climatic conditions were quite easy to explain, he observed.
    "What happens on clear nights is that the ground surface cools as a result of radiation to space and you get a layer of cold air close to the ground - this has been well-known for a hundred years or so.
    "On such nights, if you were to go up a tower, etc, to the height of a turbine (approximately 70m), then you would find a natural difference in temperature - up to a few degrees warmer than it was at the ground. This is perfectly natural.
    "If you put a rotating turbine into this scenario then you start to bring some of this warmer air from the turbine height down towards the cooler ground-level surface. Equally, you will be moving cold air from the surface higher up. This is how you see the warming effect.
    "Although it is getting warmer at the surface, it is not adding heat anywhere; it is just mixing it up."
    Prof Mobbs said the team's data revealed that the impact of the turbines was "just one very small effect alongside many other existing effects".
    But he added: "For us it is significant that we found it because if we did not find it then people could have thought that maybe there was something there but it had not been recorded.
    "We have found it and we can prove that it is very small. There are much bigger effects going on rather than the installation of the wind farm, such as nearby forests or changes in altitude."

    Science And Tech-SKULL ECHOES ARE THE NEW PASSWORDS

    SKULL ECHOES ARE THE NEW PASSWORDS


    SkullConduct Diagram
    SkullConduct Diagram
    The password is inside the skull.
    Passwords fail. Human memory is weak, so we pick familiar terms. To avoid familiar terms, logins require long passwords, with numbers and capitalization and special characters. Humans forget these, because they’re complicated, and so they have to answer security questions, which are things familiar to the person, and therefore discoverable. The greatest failure in online security is often fallible memory. Researchers from Perceptual User Interfaces have a better idea, located inside people’s heads. It uses the unique sounds their skulls make.
    From the paper:
    We present SkullConduct, a biometric system that uses bone conduction of sound through the user’s skull as well as a microphone readily integrated into many of these devices, such as Google Glass. At the core of SkullConduct is a method to analyze the characteristic frequency response created by the user’s skull.
    Essentially, because every skull is different, when the device plays a specific sound pattern into a person’s head, it will make a unique sound back, as it bounces around and reverberates through the user’s head. Once set up, the device can recognize the pattern again when re-worn, creating a new kind of useful password.
    The study was small, with just ten users, and it focused on Google Glass, a wearable with as uncertain a fate as any. But the science behind bone conductivity passwords seems pretty sound, so we should listen for similar designs in the future.

    Science And Tech-Bangladesh Bank Hackers Compromised SWIFT Software

    Bangladesh Bank Hackers Compromised SWIFT Software


    Swift code bank logo is displayed on an iPhone 6s on top of Euro banknotes in this picture illustration made in Zenica, Bosnia and Herzegovina on January 26, 2016.

    The attackers who stole $81 million from the Bangladesh central bank probably hacked into software from the SWIFT financial platform that is at the heart of the global financial system, said security researchers at British defense contractor BAE Systems.
    SWIFT, a cooperative owned by 3,000 financial institutions, confirmed to Reuters that it was aware of malware targeting its client software. Its spokeswoman Natasha Deteran said SWIFT would release on Monday a software update to thwart the malware, along with a special warning for financial institutions to scrutinize their security procedures.
    The new developments now coming to light in the unprecedented cyber-heist suggest that an essential lynchpin of the global financial system could be more vulnerable than previously understood to hacking attacks, due to the vulnerabilities that enabled attackers to modify SWIFT’s clientsoftware.
    Deteran told Reuters on Sunday that it was issuing the software update “to assist customers in enhancing their security and to spot inconsistencies in their local database records." She said "the malware has no impact on SWIFT’s network or core messaging services."
    The software update and warning from Brussels-based Swift, or the Society for Worldwide Interbank Financial Telecommunication, come after researchers at BAE, which has a large cyber-security business, told Reuters they believe they discovered malware that the Bangladesh Bank attackers used to manipulate SWIFT client software known as Alliance Access.
    BAE said it plans to go public on Monday with a blog post about its findings concerning the malware, which the thieves used to cover their tracks and delay discovery of the heist.
    The cyber criminals tried to make fraudulent transfers totaling $951 million from the Bangladesh central bank's account at the Federal Reserve Bank of New York in February.
    Most of the payments were blocked, but $81 million was routed to accounts in the Philippines and diverted to casinos there. Most of those funds remain missing.
    Investigators probing the heist had previously said the still-unidentified hackers had broken into Bangladesh Bank computers and taken control of credentials that were used to log into the SWIFT system. But the BAE research shows that the SWIFT software on the bank computers was probably compromised in order erase records of illicit transfers.
    The SWIFT messaging platform is used by 11,000 banks and other institutions around the world, though only some use the Alliance Access software, Deteran said.
    SWIFT may release additional updates as it learns more about the attack in Bangladesh and other potential threats, Deteran said. It is also reiterating a warning to banks that they should review internal security.
    “Whist we keep all our interface products under continual review and recommend that other vendors do the same, the key defense against such attack scenarios is that users implement appropriate security measures in their local environments horse-guard their systems,” Deteran said.
    Adrian Nish, BAE's head of threat intelligence, said he had never seen such an elaborate scheme from criminal hackers.
    "I can't think of a case where we have seen a criminal go to the level of effort to customize it for the environment they were operating in," he said. "I guess it was the realization that the potential payoff made that effort worthwhile."
    A Bangladesh Bank spokesman declined comment on BAE'sfindings.
    A senior official with the Bangladesh Police’s Criminal Investigation Department said that investigators had not found the specific malware described by BAE, but that forensics experts had not finished their probe.
    Bangladesh police investigators said last week that the bank's computer security measures were seriously deficient, lacking even basic precautions like firewalls and relying on used, $10 switches in its local networks.
    Still, police investigators told Reuters in an interview that both the bank and SWIFT should take the blame for the problems. "It was their responsibility to point it out but we haven't found any evidence that they advised before the heist," said Mohammad Shah Alam, head of the Forensic Training Institute ofthe Bangladesh police's criminal investigation department, referring to SWIFT.
    Thwarting future attacks
    The BAE alert to be published on Monday includes some technical indicators that the firm said it hopes banks could use to thwart similar attacks. Those indicators include the IP address of a server in Egypt the attackers used to monitor use of the SWIFT system by Bangladesh Bank staff.
    The malware, named evtdiag.exe, was designed to hide the hacker's tracks by changing information on a SWIFT database at Bangladesh Bank that tracks information about transfer requests, according to BAE.
    BAE said that evtdiag.exe was likely part of a broader attack toolkit that was installed after the attackers obtained administrator credentials.
    It is still not clear exactly how the hackers ordered the money transfers.
    Nish said that BAE found evtdiag.exe on a malware repository and had not directly analyzed the infected servers. Such repositories collect millions of new samples a day from researchers, businesses, government agencies and members of the public who upload files to see if they are recognized as malicious and help thwart future attacks.
    Nish said he was highly confident the malware was used in the attack because it was compiled close to the date of the heist, contained detailed information about the bank's operations and was uploaded from Bangladesh.
    While that malware was specifically written to attack Bangladesh Bank, "the general tools, techniques and procedures used in the attack may allow the gang to strike again,"according to a draft of the warning that BAE shared with Reuters.
    The malware was designed to make a slight change to code of the Access Alliance software installed at Bangladesh Bank, giving attackers the ability to modify a database that logged the bank's activity over the SWIFT network, Nish said.
    Once it had established a foothold, the malware could delete records of outgoing transfer requests altogether from the database and also intercept incoming messages confirming transfers ordered by the hackers, Nish said.
    It was able to then manipulate account balances on logs to prevent the heist from being discovered until after the funds had been laundered.
    It also manipulated a printer that produced hard copies of transfer requests so that the bank would not identify the attack through those printouts, he said.

    Delivery drones have yet to begin showing up at doorsteps with packages from Amazon. But a new breed of drones could eventually begin carrying the most precious package of all in the form of human lives.
    One such passenger drone resembles a giant quadcopter that can carry a single passenger on 23-minute flights at speeds of about 62 miles per hour. The Chinese startup EHang unveiled the drone, called the Ehang 184, at the 2016 Consumer Electronics Show in Las Vegas in early January. Passengers use a tablet to set waypoints for the drone to follow and can click once for both takeoff and return, but the drone itself automatically handles the rest of the flying decisions. EHang representatives told Tech Insider and other news publications that they hope the passenger drone can hit the market starting sometime in 2016.
