Future car

           Future car technologies for your road trip in 2020


COMPARING THE AUTO INDUSTRY to the computer industry is like comparing two different generations of technology. We’ve got super-fast smartphones and iPods streaming Rhapsody in our pockets, but satellite radio and clunky GPS devices attached to our dashboards.

Automakers are aware they’re a little behind the times, and by 2020, many are promising dashboard and safety systems as sophisticated as iPads — maybe even more so.



 1. Wifi

Obvious, but vital; most of the technologies on this list would be fairly useless if the car wasn’t a rolling hotspot. Several auto manufacturers are already working on developing wifi for cars. In fact, connected cars are the third fastest-growing technological device, following smartphones and tablets.

Ford has introduced this in some models with their Sync system, and Toyota is working with Intel on developing one of their own. Ideally, these systems will also have the ability to connect to your home network, allowing you to transfer information from your computer or laptop directly to your car.





2. Voice recognition

I take it back — this is the most vital technological advancement in automobiles. If texting increases accident rates, what will happen when drivers can tweet, update their Facebook page, and watch videos on YouTube?

Voice recognition is still making its way from novelty to necessary, even in the smartphone world, as it’s proven a difficult technology to master. But there’s arguably a more urgent need to succeed in this field for car manufacturers than in any other industry; already, the US Department of Transportation is calling to require voice input control of smartphones, mp3 players, tablets, and any other devices drivers may use in the car.

Unfortunately, this technology may also prove to be the most expensive for auto makers. As of now, Apple’s Siri is the only voice recognition system that’s been highly praised — and even Siri is a long, long way from whatever Kirk had on the Enterprise.




3. Digital dashboard


You’re on the road and it’s time to find a hotel. Today, you might fumble with your phone, use an app to search for something nearby, and get directions. Or maybe you’d use that GPS device suction-cupped to your window.

But by 2020, your dashboard will likely resemble a giant iPad. Ideally, that means your car’s system can be linked to whatever cloud service your smartphones and tablets use, allowing you to keep up with texts, calls, emails, social network updates, and apps from behind the wheel. So when you’re ready to check in, you can just open apps like HRS Hotel Portal with a vocal command and talk your car through a map-based search, browse rates and room types, view photos and videos (while you’re parked, hopefully), and book a room.

Toyota calls it HMI (Human-Machine Interface), a system they’re already working on in partnership with Intel and Microsoft. These digital dashboards may turn your USB mobile broadband modem or smartphone into a wireless router, like Ford’s Sync system. Or they could connect with Bluetooth devices like Kia’s Uvo, so making calls and finding music are all voice-controlled.



4. Holographic displays

GEElab (Games and Experimental Entertainment Laboratory) wins here for possibly the best project title ever — they’re currently working on an in-car entertainment system tentatively named “Enjoyable Interactions in the Rear Seat.”

According to Business Review Europe, this system will combine holographic displays with motion sensors to create applications for folks in the backseat that’ll be similar to Microsoft Kinect and Nintendo Wii. While games are the goal, the resulting holographic technology could also be used to display dashboard and control info, as well as GPS.

Even now, some cars are equipped with technology only a step or two away from holographics. S-class and CL-class Mercedes feature SplitView screens, which are pixelated in a way that projects two completely different images — one for the driver and one for the passenger. However, the system is not yet legal in all states.



5. Car-to-car communication


Unlike driver-to-driver communication, this (probably) won’t involve middle fingers. Once cars are connected thanks to technologies such as Intel’s M2M (Machine-to-Machine), they’ll be able to share data with other cars on the road and warn drivers of accidents, as well as figure out alternate routes based on real-time information — which in turn will help cut down on traffic and increase safety on the road.


As an example, the Car2Car Communication Consortium points out a fairly commonplace scenario: A motorcycle is riding alongside or just behind a larger vehicle on a main road, while you wait at an upcoming intersection to make a right turn onto that road. The larger vehicle turns off the road, and because you still can’t see the motorcycle, you pull out — right in its path. With car-to-car technology, both you and the motorcyclist would receive a warning early on, which would likely help avoid a collision.


6. Car-to-X communication


There’s some overlap between car-to-car and car-to-X technology. BMW prefers car-to-X, as they’re looking into designing a system that allows cars to communicate with other systems outside of those in vehicles.

One of these research projects is known as PROTON-PLATA (programmable telematics onboard radio), conducted by DEUFRAKO, a Franco-German cooperation in traffic research. The project is addressing the issues posed by a wide range of digital standards and radio frequencies currently in use in digital broadcasting and mobile telecommunications, all of which are continually upgraded into their “next generations” about every two years. Because the life cycle of a car is significantly longer, drivers are constantly “falling behind” when new systems are released.

The PROTON-PLATA project is researching whether SDR (software defined radio) is the possible answer — technology which will allow all of these systems to be implemented in a single hardware unit.

BMW’s AMULETT (active mobile accident avoidance and mitigation of accident effects through cooperative data acquisition and tracking technology) project focuses on using car-to-X systems to actually communicate with people. The system includes a radio transponder that cyclists and pedestrians wear, which notifies the driver when the wearer is crossing the street or stepping out from behind a parked car.
 

7. Digital goods

Also known as apps. A shift from hardware to software in car systems will mean that by 2020, you won’t need to bring your car in for an actual installation every time you need an upgrade. Just like with your smartphone, it’ll be as simple as visiting the app store. And as Car and Driver pointed out, these systems are relatively inexpensive for car makers, as the technology is already standard in the computer and mobile industries.

This paves the way for developers to focus on entertainment and utilities apps specifically for the driver. Apps to find your “perfect match” on the road. Apps that adjust the music to suit your mood. Apps that adjust the lighting to calm you in stressful situations. Apps that wake you up when you start to drift off thanks to soft music and dim lights.



8. Remote control
 

At the Busan International Motor Show in South Korea last month, Hyundai Motor introduced Bluelink, an IT controlling system that allows smartphone owners to find, unlock, and start their car remotely, as well as turn on the AC and opt to receive texts if there is damage or a break-in. BMW is working on remote-controlled parking.

The next version? Maybe an app that memorizes your preferences and utilizes GPS to detect your proximity to your car. By the time you slide into the driver’s seat, the AC is cranked, the music is on, and there’s a hot cup of coffee in the cupholder. (It’s possible, right?)






                                                       

9. Intuitive safety features

Safety and emergency notifications can be helpful in preventing accidents but, in many cases, a barrage of beeps and ominous blinks only adds to a stressful driving situation.

The solution for some manufacturers is a “pre-safe” system. Scenario: A car in front of you slams on the brakes, and your car senses it’s too close. The system primes the brakes so that even a light tap of the pedal will apply full force, increasing your chances of stopping in time.

In emergencies, your car may even be able to take control and guide you to safety. For example, if your car detects you’re having a heart attack or losing consciousness, BMW’s Emergency Stop Assistant system will locate your car, flip on the emergency flashers, use sensors and video to monitor surrounding traffic, steer you safely off the road, and place a 911 call.






10. Invisible chauffeurs and copilots




Technically, the invisible chauffeur already exists — Google has been test-driving driverless cars in California. Nevada recently approved licenses for “autonomous vehicles,” meaning if you see an empty car cruise down the strip, there’s actually a chance it isn’t a drunken hallucination. And General Motors claims it will have its own driverless cars on road by 2018. An invisible co-pilot, however, has already made its way into upcoming models.

Your car will help you parallel park — if you’ve got a Lexus LS 460 L, the Advanced Parking Guidance System asks you to align the car and put it in reverse before tapping a button. After that, take your hands off the steering wheel, control the speed with your foot on the brake, and let the car manueuver its way in.

Cruise control can go beyond staying at a set speed. With radar sensors on the front of your car, the system will detect the speed of and distance between you and the car in front of you, adjusting cruise control to keep a safe distance.

The co-pilot will also watch out for lateral collisions by using a variety of sensor technologies — lidar, radar, ultrasound, video — to monitor the area surrounding the car and, when another car or object gets too close, applying a “directional impulse” tug to the steering wheel.





11. Health monitor

Ford has announced the development of a car seat with sensors to monitor your heart rate using electrical impulses. Mitsubishi Electric has plans to take this much further, and they believe such an interface will be a reality within the decade.

“Things like the seat position can be customized for all kinds of people,” said Kiyoshi Matsutani, Manager of Automotive Electronics Development Center, at the 2011 Tokyo Motor Show. “This is done through personal ID, facial temperature measurement, or heart-rate measurement using a Doppler sensor. In this way, the system senses the person’s health condition on that day. The aim is to position the seat and steering to match the driver, and provide information to help with safe driving.”




12. Eco-mode





Researchers at organizations like the Continental Corporation in Germany are focused on using technology to make cars more eco-friendly. According to Popular Mechanics, Continental is developing an interface that includes an “eco” mode, which can search for the most economical route and offer other “green” tips. The system rewards eco-friendly driving behavior — when the four-leaf clover display is filled green, the driver is eligible for rewards from their dealership.


13. Financial GPS

If your future car will be able to communicate with other cars, systems, devices, and humans, why not your bank? BMW has developed a key that functions as a credit card. In 2020, your entire car might become one. Skymeter calls it “Financial GPS.”

“With Financial GPS, consumers can get one bill at the end of the month for every car-related cost: their parking, their insurance, their lease, their roads, even full repairs coverage,” said Kamal Hassan, Skymeter CEO, in a Mashable interview.

“Everything would be paid automatically per minute or per mile, based on your actual driving and parking. Drivers could then control their costs. Not driving for a week would save you money on your lease, your insurance, and even your municipal tax bill.”

This may mean we’re facing a future in which toll passes forever lost between car seats have become obsolete.

How to Prevent Hacking

Ways to Protect Your Computer From Being Hacked

Computer hacking can occur in a number of ways. Your computer system itself can be hacked and mined for personal information. Your blog or website can be compromised if a hacker obtains your password. Your email can be hacked if you click on a fraudulent link and you may not be able to retrieve your email and other information you've registered in your account. Use these steps to safeguard your computer and prevent computer hacking.





1. Perform required software updates for your operating system and web browser. Hackers attack where they see weakness. A system that hasn't been updated recently has flaws in it that can be taken advantage of by hackers.

    Go to the Microsoft Update website to download patches and secure the most recent version of your operating system. If you have a Mac, click on the apple in the top left of your screen and choose "Software Update."






2.  Install a firewall on your computer. Firewalls forbid outside threats such as hackers and viruses from gaining access to your system. Personalize your firewall settings during the setup process to reflect how much data you want to allow into your system from the Internet, and update your firewall regularly. 



3. Change your passwords often. Use a different password for each website you regularly log into, and make sure your passwords are long and intricate so that they're harder to guess. It's especially important to keep your banking and other financial accounts secure. 



4. Purchase or download anti-virus software. Many computers come pre-installed with certain anti-virus software, but if not, or if you want more powerful software, research online to find what product suits you. Anti-virus software is crucial to keep your computer healthy. A "sick" computer, or one racked with viruses, is more susceptible to hacking. Set your preferences so your anti-virus software updates automatically. 





5.  Install anti-spyware/adware programs onto your system. This type of intrusion is not as dangerous as a virus, but adware places advertisements onto your browser and incorporates pop-ups into your programs. This can slow down your computer, making you vulnerable to a hacker. Spyware can survey your Internet behavior and copy your passwords to use for illegitimate purposes. 




6.  Delete emails from unknown sources. Never click on an emailed link that looks questionable. 






 7.  Don’t Give Others Physical Access

If a hacker is literally sitting in front of your computer, there’s really nothing you can do to stop them from doing what they want. With physical access, there’s a way around everything. However, if you follow any 2 0r 3 other tips in this article and don’t let them anywhere near your computer, they can’t hack it. Try to keep your computer as secure and isolated as possible, and you won’t have any hacking problems!


 If you follow above simple rules in this article, you’ll be safe from hacking.

BIG DATA

Big data is a popular term used to describe the exponential growth and availability of data, both structured and unstructured. And big data may be as important to business – and society – as the Internet has become. Why? More data may lead to more accurate analyses.

 

Big data defined

As far back as 2001, industry analyst Doug Laney (currently with Gartner) articulated the now mainstream definition of big data as the three Vs of big data: volume, velocity and variety1.
  • Volume                                                                                                    Many factors contribute to the increase in data volume. Transaction-based data stored through the years. Unstructured data streaming in from social media. Increasing amounts of sensor and machine-to-machine data being collected. In the past, excessive data volume was a storage issue. But with decreasing storage costs, other issues emerge, including how to determine relevance within large data volumes and how to use analytics to create value from relevant data.                                
  • variety                                                                                           The next aspect of Big Data is its variety. This means that the category to which Big Data belongs to is also an essential fact that needs to be known by the data analysts. This helps the people, who are closely analyzing the data and are associated with it, to effectively use the data to their advantage and thus upholding the importance of the Big Data.                      
  • Velocity                                                                                         Data is streaming in at unprecedented speed and must be dealt with in a timely manner. RFID tags, sensors and smart metering are driving the need to deal with torrents of data in near-real time. Reacting quickly enough to deal with data velocity is a challenge for most organizations.
      At SAS, we consider two additional dimensions  when thinking
      about big data.
  • Variability                                                                                  In addition to the increasing velocities and varieties of data, data flows can be highly inconsistent with periodic peaks. Is something trending in social media? Daily, seasonal and event-triggered peak data loads can be challenging to manage. Even more so with unstructured data involved.
  • Complexity                                                                              Today's data comes from multiple sources. And it is still an undertaking to link, match, cleanse and transform data across systems. However, it is necessary to connect and correlate relationships, hierarchies and multiple data linkages or your data can quickly spiral out of control.

Why big data should matter to you

The real issue is not that you are acquiring large amounts of data. It's what you do with the data that counts. The hopeful vision is that organizations will be able to take data from any source, harness relevant data and analyze it to find answers that enable 1) cost reductions, 2) time reductions, 3) new product development and optimized offerings, and 4) smarter business decision making. For instance, by combining big data and high-powered analytics, it is possible to:
  • Determine root causes of failures, issues and defects in near-real time, potentially saving billions of dollars annually.
  • Optimize routes for many thousands of package delivery vehicles while they are on the road.
  • Analyze millions of SKUs to determine prices that maximize profit and clear inventory.
  • Generate retail coupons at the point of sale based on the customer's current and past purchases.
  • Send tailored recommendations to mobile devices while customers are in the right area to take advantage of offers.
  • Recalculate entire risk portfolios in minutes.
  • Quickly identify customers who matter the most.
  • Use clickstream analysis and data mining to detect fraudulent behavior.

Glassy Glassy mobile Phone


 Glassy Glassy:
 



Tokyo-based designer Mac Funamizu has done it yet again – coming up with a fluid concept design that makes us wish prevailing technology has what it takes to manufacture a thing of beauty such as the Glassy Glassy cell phone concept. The entire thing is transparent until you turn it on, where the screen and keypad will then light up for you to press accordingly. No idea whether it has the tensile strength of a standard cell phone, or will it crack all too easily during one’s travels? One more thing – where the heck is the battery stowed away?



'Glassy Glassy' translucent mobile phone concept is no exception.

The double layers of glass shield an incredibly sleek and futuristic mobile phone design. There are two ‘Glassy Glassy’ concepts, a glass mobile phone and a clock that can stand on its own for desktop use.

Mac Funamizu has his pulse firmly on the vein of future design, and I hope his innovative work comes into fruition.

Google Glass




Google Glass is a type of wearable technology with an optical head-mounted display (OHMD). It was developed by Google[9] with the mission of producing a mass-market ubiquitous computer.[1] Google Glass displays information in a smartphone-like hands-free format.[10] Wearers communicate with the Internet via natural language voice commands.[11][12] Google started selling a prototype of Google Glass to qualified "Glass Explorers" in the US on April 15, 2013, for a limited period for $1,500, before it became available to the public on May 15, 2014,[13] for the same price.
On January 15, 2015, Google announced that it would stop producing the Google Glass prototype but remained committed to the development of the product. According to Google, Project Glass was ready to "graduate" from Google Labs, the experimental phase of the project.[14]

It's amazing how the Project Glass team has managed to squeeze all of its features into a tiny ‘computer’ supported on a lightweight yet strong frame.
Google Glass is packed with Bluetooth, Wi-Fi, GPS, speakers, a camera, microphone, touchpad and possibly a gyroscope that detects head-tilts. Then there’s the main piece, a tiny screen the size of your finger, that shows you all the information you need at your finger tips.


Google Glass was developed by Google X,[16] the facility within Google devoted to technological advancements such as driverless cars.
Google Glass is smaller and slimmer than previous head-mounted display designs.[17]
The Google Glass prototype resembled standard eyeglasses with the lens replaced by a head-up display.[18] In mid-2011, Google engineered a prototype that weighed 8 pounds (3,600 g); by 2013 they were lighter than the average pair of sunglasses.[1]
In April 2013, the Explorer Edition was made available to Google I/O developers in the United States for $1,500.[19]


A Glass prototype seen at Google I/O in June 2012
The product was publicly announced in April 2012.[20] Sergey Brin wore a prototype of the Glass to an April 5, 2012, Foundation Fighting Blindness event in San Francisco.[21][22] In May 2012, Google demonstrated for the first time how Google Glass could be used to shoot video.[23]
Google provided four prescription frame choices for $225 and free with the purchase of any new Glass unit. Google entered in a partnership with the Italian eyewear company Luxottica, owners of the Ray-Ban, Oakley, and other brands, to offer additional frame designs.[24] In June 2014, Nepal Government adopted Google Glass for tackling poachers of wild animals and herbs of Chitwan International Park and other parks listed under World heritage sites. Gurkha Military currently uses Google Glass to track the animals and birds in the jungle. This operation led to the latest development in military operation. Google Glass was used in military for the first time in the world by Nepal.[25]
In January 2015, Google ended the beta period of Glass (the "Google Glass Explorer" program).[14][26]

More recently, participants of the #ifihadglass competition can get an opportunity to buy Glass if they give the most creative Tweet or Google+ comment. For the rest of us, we’ll just have to wait until they iron out the rough edges before we can put on a pair.

LASER TECHNOLOGY

 LASER
 Light Amplification by Stimulated Emission of Radiation.)


Lasers provide the archetypal example of how a discovery in basic physics led to an invention, several decades later, that was unpredictably world-changing.

What are lasers?

Lasers are devices that emit narrow beams of intense electromagnetic radiation (light). The term laser originated as an acronym for “light amplification by stimulated emission of radiation”. A laser beam has the special property that the light waves emitted are all in step with one another – coherent – and usually of one wavelength, or colour. There are many different kinds of lasers, from giant installations emitting powerful pulses of high-energy radiation, such as X-rays, to tiny devices etched onto semiconductor chips producing infrared light.

Many different kinds of material can be made to “lase” – such as gases, crystalline solids, glasses and polymers – and which one is used depends on the application. Some lasers are designed to emit a continuous beam while others can spit out rapid pulses of light that are ultra-short. The wavelengths of light generated by certain types of laser can even be “tuned” for specific applications, making them extremely versatile.

Lasers offer a way of generating, controlling and directing intense light in remarkable ways, yet when they were first invented, physicists were not sure what they could be used for – they were famously described as a “solution looking for a problem”. In fact, although the first laser was constructed in the 1950s, practical applications did not appear until a couple of decades later – as is often the case in science. Since then, thanks to research activity in both university physics departments and companies, including those in the UK, lasers have become ubiquitous and are central to many technologies that are used in manufacturing, communications, medicine and entertainment.
Today, lasers are key tools in manipulating and communicating information (in CD and DVD players, supermarket barcode readers and broadband telecommunications), in measurement (surveying and environmental studies), chemical analysis (of foods, medical specimens and materials) and, increasingly, in transforming materials (welding, cutting and etching, printing, and surgery).
Research into lasers continues apace – new types of laser are being developed with a variety of characteristics and potential applications. In some cases, the result is a cheaper, more compact portable device designed for a specific use, or a more powerful laser used to generate power, for instance. UK university physics departments are at the forefront of many of these areas. In particular, physicists in the Central Laser Facility (CLF) at the Rutherford Appleton Laboratory develop novel high-powered laser systems and make them available for both pure and applied research.

The science


The laser would never have been developed without a profound understanding of an area of fundamental physics – quantum theory. The principle behind the laser goes back to the world’s most famous physicist, Albert Einstein, who in 1917 proposed a theory of stimulated light emission. Einstein had previously shown that light was composed of tiny packets of wave energy called photons (the wavelength depending on the energy).
He theorised that if the atoms that make up a material are given excess energy and so emit photons, these photons could stimulate nearby atoms to emit further photons, creating a cascade effect. All the photons would have the same energy and wavelength and move off in the same direction.
However, it was not until 40 years later that physicists were able to convert this idea into a practical laser. The principle is that the “active” material has first to be pumped with energy from another light source or an electrical current. The resulting stimulated light emission is then amplified by bouncing the light back and forth through the lasing material in a mirrored cavity, so stimulating more emission, before it escapes through a transparent mirror section as a laser beam. A device that amplified microwaves was constructed in 1953 by Charles Townes and colleagues at Columbia University. Townes shared a Nobel Prize in Physics in 1964 with Nikolay Basov and Aleksandr Prochorov of the Lebedev Institute in Moscow (who independently also demonstrated what came to be called a maser).
The next few years saw a race to build the first visible light laser. Theodore Maiman at Hughes Research Laboratories in California pipped Townes and his team at the post when he built the first working laser in 1960 using ruby as a lasing medium – although who should be credited for the laser’s invention was then hotly contested.
Initially the laser concept was not taken very seriously, nevertheless the 1960s saw a huge expansion in laser research including the development of high-power gas lasers, chemical lasers and semiconductor lasers. However, they were still rather specialised research tools. By the 1970s, semiconductor lasers that worked at room temperature had been developed and this led to the advent of the compact disc (CD).
Without the discovery of lasers, the entire fundamental field of cold atoms would never have opened up. Research in this field has led to the award of several Nobel Prizes in Physics, including the discovery of Bose–Einstein condensates (BEC). BEC has opened the door to a host of applications such as atom lasers, improved atomic clocks and quantum computers.
Today, semiconductor diode lasers are the most common type, found in industry, commerce and the home Applications.

Information Technology

    The largest application of lasers is in optical storage devices (e.g. CD and DVD players), in which a focused beam from a semiconductor laser, less than 1 mm wide, scans and reads the disc surface. Other everyday uses include barcode readers, laser printers and laser pointers. Over the past 25 years the publishing and newsprint industries have been revolutionised by the use of lasers, which have replaced traditional “hot metal” printing.
    Telecommunications
    The second largest application is in fibre-optic communications. Broadband depends on the transmission of light pulses alongoptical fibres, which are generated and relayed via lasers. This is made possible by fibre amplifiers, invented in the UK, which are an important component in long-distance fibre links.

    Medicine

    Lasers can deliver concentrated energy in the form of fine controllable light beams, so physicians soon took advantage of them to perform micro-surgery, which involves less pain and scarring, lower blood loss and shorter recuperation time in hospital. Laser beams delivered via flexible optical fibres allow surgeons to reach inside the gut, for example, and seal a bleeding ulcer. One of the most publicised uses of lasers is in eye surgery to treat disease and, increasingly, improve bad eyesight.

    Manufacturing

    Lasers can deliver enough power to heat and melt metal joints, and so are used for welding, as well as for cutting. When controlled by a computer, a laser can cut complex designs into a material such as wood or paper, as is increasingly being seen in furniture and other home goods.
    Measurement and analysis
    Lasers have long been used by the military for range-finding, but now even estate agents employ laser tape measures. Because lasers can be tailored to produce specific wavelengths, they are used to analyse chemical and physical structure, and so are used in factory quality control and to monitor environmental pollutants remotely. Lasers can be used for a type of measurement called interferometry which can measure tiny changes in distance.

    Scientific research

    Virtually every university science department in the UK relies on lasers for some aspect of its research programmes – they have become indispensible research tools. Without lasers, many recent discoveries would never have been made, which illustrates the synergic relationship between developments in physics and other fields. Lasers interact with matter at the quantum level in very specific ways and so are important probes in research. They can be used to follow chemical reactions and elucidate structure at the atomic and molecular scale. Increasingly, life scientists are employing lasers in new types of microscopy designed to highlight cellular structures.

Current developments


Physicists are continually developing new lasers and many UK teams are involved in these projects. These include nanoscale devices that emit light and that are expected to find use in chemical and biological sensors on “lab-on-a-chip” devices. The University of St Andrews, for example, has developed laser optical tweezers to manipulate biological cells to contribute to the burgeoning area of biophotonics. Several UK research groups are developing a new semiconductor laser called the quantum cascade laser, which promises to be an excellent source of terahertz radiation (between infrared and microwaves) now being introduced for national security screening. New laser technology will also play a role in developing the all-optical computer.
Researchers at the universities of Bath and Southampton pioneered a type of laser based on micro-structured optical fibres, which can produce light across the entire visible spectrum. Fibre lasers can be made to emit low-power light, allowing physicists to manipulate single photons. These are needed for fundamental experiments aiming to explore strategies underpinning the developing concept of quantum computing, which would allow the processing of unbelievable amounts of data, and also quantum cryptography, which offers an ultra-secure means of transmitting data.
Fibre lasers may also provide the next generation of very high power devices, producing X-rays for many kinds of enabling research, particularly in the life sciences. The European X-ray free electron laser (XFEL), a large facility being constructed in Germany, is expected to offer X-rays at intensities not achieved before, and the UK is supporting this project. The UK’s CLF also hopes to host the world’s most powerful laser set-up, HiPER, which could demonstrate nuclear fusion as a potential clean, renewable source of energy.

Looking further ahead, researchers are undertaking nuclear physics research that could eventually lead to a gamma-ray laser to store nuclear energy, while exploitation of the atom laser might produce a whole gamut of new, and probably unanticipated, applications for the future.

Impacts


Lasers have become a multi-billion dollar industry. Even by 1994, the US National Academy of Sciences estimated that the economic impact of laser technology was $100 bn a year. In 2004, excluding diode lasers, about 131 000 lasers were sold worldwide with a value of $2.19 bn, and about 733 million diode lasers valued at $3.2 bn. In 2008, the rapidly growing fibre-laser market alone was worth $240 m and is expected to reach $500 m by 2011.
Lasers are one of the most important enabling technologies to have been developed in the past 50 years and it is difficult to evaluate their impact. Lasers not only drive the modern information economy, allowing data to be transferred quickly across the internet and to be stored economically and efficiently, but they are also an essential research tool without which modern science, technology and medicine would not progress.

OCULUS OUT




Oculus out to let people touch virtual worlds.
Los Angeles (AFP) - Behind closed doors on the show floor of the world's premier video game show, Facebook-owned Oculus was letting people touch virtual worlds.
Oculus provided a select few with an early peek at how it is trying to tackle the challenge of letting people intuitively interact with faux objects in fantasy realms.
Prototype Oculus Touch Half Moon controllers that can be gripped as easily as clasping a pistol gave in-world hands to people wearing the company's Rift virtual reality head gear.
Words such as "awesome" and "cool" sprang from the lips of those immersed in a sample virtual world where Touch controllers let them play ping pong, detonate fireworks, blast targets with ray guns, and even sock robots.
An Oculus developer appeared in the demo as a shimmering ghostly head and hands. In-world characters could toss things at or to on another, or work together on tasks such as lighting pyrotechnics.
The vision is that, people could be continents apart in the real world but play a game like tether ball together in a virtual setting.

The effect was so real that it was instinctive to stop suddenly for fear of bumping into a virtual table top, or to grab to catch a dropped toy or ping pong ball.
- Wondering what's real -
"In virtual reality, you are going to find yourself reminding your brain that this is not real," Oculus chief executive Brendan Iribe said last week during a media event in San Francisco where a market-ready version of Rift was revealed.
"It is a paradigm change."
At one point in the demo, the scene changed to outer space and everything floated in the seeming absence of gravity. After coming back to Earth, a blast of a pretend shrink ray turned one tiny.

Oculus has aimed squarely at video game lovers with Rift headsets that it will begin selling early next year.
Many developers at E3 -- the annual Electronic Entertainment Expo -- were working on games for virtual reality.
Oculus did not disclose pricing for Rift, which will launch with an Xbox controller due to an alliance with console maker Microsoft.
Combining Xbox controllers with Oculus provides a familiar way for gamers to interact with virtual worlds using Rift, so the head gear can get to market without waiting for Touch to be ready.
The alliance also raises the potential for Oculus virtual reality gear to synch with Xbox consoles as well as across the range of devices that will be powered by Windows 10 computer operating software set for release later this year.

Oculus founder Palmer Luckey unveiled the prototype Touch in San Francisco last week.
"You need to be able to pick up a gun from a table, fire it, and throw it away without even thinking about it," Luckey said.
"You can light explosives, pull robots limb from limb, punch garden gnomes... lots of cool experiences."
Facebook last year bought Oculus for some $2 billion.
- Game makers dive in -
The expansive E3 show floor was rich with VR offerings from developers working on games for immersive head gear expected to hit the market in force next year.
Queues were long through the day as people at the world's leading video game trade show jockeyed to experience what it is like to venture into fantasy worlds.
"People love VR," Robyn Gray of Other World Interactive told AFP while showing off a game that transported players to a space arena where they destroyed asteroids with friends.
"It is still like this magical, sparkly Christmas time present."
Virtual reality calls on developers to rethink approaches, taking into account factors such as how uncomfortable head gear might become after hours of play and creative new ways to interact with digital realms.

Purpose of using technology

7 Ways to Use Technology With Purpose


why are you using technology? Or more importantly, how are you using technology to better the learning in your classroom and/or school? If you are like me, then you’ve had your fair share of technology screw ups. Projects that didn’t make sense (but used the tech you wanted to bring in). Activities that were ruined by a crashing website or some technological problem. And of course you’ve probably dealt with the students, parents, and teachers that want to do things “the old way”.

in order to make sure you are using technology the right way, you must first “start with why”. If your students understand the “why” behind your technology use, then the class will have a purpose and technological glitches and issues can be worked through. If they don’t understand the “why” then any small issue could turn into a major problem.
Here are 7 ways

1. To Collaborate in Real Time
Remember when Google Docs broke onto the scene? It was magic. Students writing and sharing in real-time, able to see what the other students are doing and saying, while still working on your own part of the project or activity. Flash forward 7-8 years and now “real-time collaboration” is a must for most online software. This type of technology allow project-based learning to be monitored, documented, and done outside of the school hours.
At my school we have been using Microsoft OneNote (as well as the Google products) to collaborate in real-time. Whether it is staff planning together, students working together, or a combination of both…this technology has so many learning purposes.


2. To Reflect and Share


I used to have my students journal in their marble notebooks. And during certain activities I still do (like Writer’s Bootcamp). However, what’s nice about having students journal online and share “in the cloud” is the ability for their classmates to see what they have to say.
This is why I suggest blogging throughout the year, and not just as a project. Make blogging a part of your student’s life and you’ll be able to see which topics, ideas, projects, and activities really impacted them. Sometimes it may not be what you thought…and sometimes their simple act of sharing will bring the class together in ways you never could have imagined.


3. Better Research


After I finished writing my Master’s thesis on ‘peace education in the 21st century’ I talked with my mom about her writing process in graduate school. It sounded awful… She would have to go to the library, find a resource, read almost the entire resource, make copies of the pages she wanted to use, and literally “cut it out” and “paste it on” her typewritten document.
Technology has made research simple and more time efficient. I’m not talking about typing a question into google, I’m specifically focused on searching journal databases like ERIC through places like Ebscohost. A nice search phrase will turn up hundreds of peer-reviewed results which can be sorted many different ways (such as by date or full-text article). Those articles that you choose can then be automatically scanned for your keywords, read the specific parts you want, and use what is applicable with a simple copy and paste and proper citation already set up and ready to go.
How often do we really teach students how to research in today’s world? Or do we expect them to learn on their own like we did?


4. Write and Re-Write


Using tools such as Google Docs, the new Microsoft Word, or Draft students are able to write and edit on the fly. They can get feedback from peers and teachers…and then choose whether or not to accept that feedback on their writing. Technology has changed the writing process in much the same way it has changed the research process.
The most important part of writing is the revising and editing. Yet, we often take it for granted. Instead let’s use the technology to track what types of changes students have made, and if they are making the same mistakes in their writing over and over again. That way, the “re-writing” process can have a direct impact on how much they improve and change some of their writing habits over time.


5. Make Something (that matters)


This may be my favorite way to use technology with a purpose. Students now have the ability to make movies, songs, pieces of art, websites, apps, games etc–with technology. However, too often we ask students to make something that does not matter. We ask them to make a movie or poster or presentation that has no direct impact on the world around them.
Instead, let’s challenge ourselves to start making technology matter. Make iMovies that can be uploaded to Youtube and have a purpose. Make games with a meaning. Make apps that matter. Yes, there is a time for fun and games. But if that is all we use technology for in school…then we shouldn’t be surprised when that is all students use technology for once they get out of school.

6. Keep a Digital Record


Digital portfolios are a must. Not because colleges will want and need them in the future (which is happening sooner than you think). Not because it is a cool way to show off what you’ve done in class. Digital portfolios are a must because they show learning growth.
The best way to show how much a student has learned is through a digital portfolio. You can look back over time and what they’ve created, written, and done in school. And how that work has improved (and in what ways) throughout their schooling. When students know their work will be on display and recorded, they also take pride in what they do because it will last.
Ask yourself, are you making “digital fridge art” or something worth keeping?


7. Mastery Assessments


Think about the last time you gave an assessment. I’m sure you prepared students for it during class, gave them materials to study, and supported them during the assessment. However, there were definitely a few students who struggled on this assessment. What happens next? You can either give them a re-take, give them another similar assessment, or say that is there only chance.
If you gave them a digital assessment you’d be able to see exactly which questions they got wrong in comparison to the entire class. You could see how much time they spent on the question and if the answer they chose was way off base…or close. You could tailor a new assessment based on just the problems/questions they got wrong and make sure they achieved mastery on those topics before moving forward.
Technology should change the way we do assessments forever, yet sadly many of us still give tests the same way we did 10 years ago. This is a tech purpose we can’t avoid any longer.
