U disk fingerprint identification will no longer have sex photo

  After the iPhone and many Smartphones also joined the fingerprint recognition, fingerprint recognition function ensures the safety of cell phone use, because there is too much important information, such as payment information, internal company documents, and so on. Now, they even have fingerprint recognition. Samsung Galaxy S5 screen

  Fingerprint recognition to guarantee payment security, such as Apple is about to enter the Chinese Pay mobile payment service is relying on fingerprint recognition to ensure fast, secure and reliable mobile experience.

  Now, in addition to the outside of the mobile device, USB drives start to add fingerprint recognition, this means that if you pick up a USB drive on the road if you are not the owner, you have no way to view the information inside the u, even if there are 100 million of the trade secrets, you have nothing. Of course, if you are accidentally lost USB stick person, you can rest assured, because without your fingerprint information inside others even pick up your Flash drive cannot see.

  A few days ago, Apacer technology has unveiled a equipped with a fingerprint recognition of USB flash drive, model AH650. This USB flash drive is equipped with a capacitive fingerprint sensor supports up to saving 10 fingerprint data. USB drive disk space is classified as protected and non-protected areas, protected areas requires fingerprint authentication before they can access, important files can be placed in the reserves.

  U use fingerprint recognition is the benefit of higher speed, accuracy, and support 360 ° identification, easy to use.

  Apacer USB drive using MLC Flash particles interface for USB 3.0, official says top speed of up to 130MB/s, has storage capacity of 2 versions, 32GB and 64GB, there are two colors, silver and gold.

  MCL Flash particle is the mainstream products in moderate speed, durability, price, and support about 3000---10000 writing life.

  MLC was first developed by Intel, which is two bits of information into a floating gate, then potential difference (Level) of the charge through the precision of voltage control reading and writing memory cells. Assumed to 4 species voltage control, and one transistor can access 2 bits of data, if control 8 species voltage on can access 3 bits of data, makes Flash of capacity sharply upgrade, similar Rambus of QRSL technology, through precise control floating gate Shang of charge number, makes its rendering out 4 species different of storage State, each species State representative two a II into business numerical (from 00 to 11).

  On the market about 3 Flash particle, a SLC particles, it has approximately 100,000 erase/write life, but the cost is very high; another is TLC particles and low cost, but life is short, only supports 500 writing life. In contrast, the MLC cost medium, live medium, so favored by manufacturers.

  Currently Apacer AH650 price hasn't been announced, but for general hardware encryption with different price should not be very cheap, but this is, after all, designed for users with special needs, the price may be expensive, but more data security.

Experts Microsoft has more Edge than IE security is recommended

Experts: Microsoft has more Edge than IE security is recommended!

  On the Internet Explorer browser exposes vulnerabilities every day, all the time the fact that there is no risk of black, already is not a big secret, which is a security nightmare for Microsoft. Even more interesting is that whenever Internet Explorer browser were found to have big holes when many users conscious of stopping Internet Explorer, and instead preferred Google Chrome or Mozilla Firefox browser.

  However, the new Windows 10 operating systems, this would be very different, because of Internet Explorer are no longer the default browser for Windows, but takes a long time to build the Microsoft Edge browser is still not perfect. It is clear that Microsoft does not want too many people to give up using their browser's tradition.

  Even if the Edge is not yet perfect, but Microsoft has already said that Edge is own by far the best browser, it not only has a new user interface and more features, but faster and more stable than any other third-party browser, focusing on more secure. Facts true? Yes, that's right. Recently, the well-known solution for vulnerability management and security company Qualys's Chief Technology Officer, is also a Windows security expert Wolfgang Kandek is often criticised, should stand up to support Edge.

  Wolfgang Kandek through a chart to tell the world, relative to the Internet Explorer browser, Microsoft Edge is a significantly more secure browser, and is one of the most secure browser in the world.

  Monthly Edge CVE is very low M & M'S iPhone 5 Case

  As the chart shows, starting in August 2015, Microsoft fixed vulnerabilities Internet Explorer browser fixes each month amount exceeded more than 10. Surprising is that in November, number of bug fixes Internet Explorer up to 25, directly into the peak this year.

Experts: Microsoft has more Edge than IE security is recommended!

  The other hand, Microsoft's new browser has too much Edge is relatively good, Microsoft fixed vulnerabilities this month only 4, sporadic in the past 2 to 3.

  In this regard, Wolfgang Kandek said: "the Edge is clearly more secure than Internet Explorer, if you can run the whole enterprise, employees want to all relevant business applications, then the Edge must be the browser of choice. " M & M'S iPhone 5 Case

  Edge really is too weak

  To be honest, Windows 10 has now been released for more than 3 months, not only system is further perfected, even so does the Edge, the equivalent of an unfinished version, it has too many areas in need of improvement. Not just random crashes of an unrecoverable situation, basic functions and also on Internet Explorer is far worse, for example, does not support full screen browse mode, also does not support drag-and-drop uploading, does not support opening multiple virtual multiple desktop browser, users looking for plugin support in the future.

  On the Edge too early to replace Internet Explorer now. Microsoft originally promised before the end of this year to provide all concerned with plug-in extensions, now and then has a miscarriage. Microsoft says the plugin extensions are working, but this feature is available by 2016 will not.

M & M'S iPhone 5 Case

  According to a previous message, expects big update of Microsoft's next Windows 10 in Redstone, may also be important upgrades on the Edge, but then had to wait until the summer of 2016.

Mobile phone to 500 yuan in fighting mobile phone market

"Don't 999 not 899, not 599, 499, 399! You can't lose, you can't buy the bait, are brands you buy, you buy are popularity! "You may think this is TV shopping is wrong, this is a true reflection of recent domestic smartphone market!

Kenzo iPhone Case

Before we liked to say thousands of phones (including below) market is dominated by domestic brands, and domestic brands often like to work at this level of the market, fuss. Indeed, thousands become domestic brand label. That such as zhongxing "high-minded" brand, to break with 599 this level of mobile phone to show their impact "high-grade" determination.

But today, perhaps ZTE had made a fatal mistake, it should not give up 599 yuan market. Starting from this month, mobile phone fighting market, defined by the concept of thousands, is not precisely describe the degree of market segmentation, because 500 mobile phone market seems to have arrived.

500 Yuan, basically is the lower limit of the domestic brands of smart phone before, unless the sale, few domestic brands will Smartphone prices plunging to less than 500 Yuan. For a long time now, smart phones less than 500 Yuan (not including those features) markets such brands of the world is basically Tianyu, Shenzhou, or shanzhai territory. Watching situation in recent days, Chinese mobile phone, to 500 Yuan and 500 yuan in fighting the following smartphone market.

Mobile phone, to 500 yuan in fighting mobile phone market?

Red rice 2A

First is millet. On June 8, the millet company announced that red phone 2A price dropped to 499 Yuan, in millet's official stock available for sale. Then take the Zhou Hongwei and his odd cool. On June 9, after the mergers and acquisitions business God, Zhou God phone Twitter claims that will be positioned in the future to a thousand Yuan and 500 Yuan, will launch the next two handset truly unbeatable prices. Shortly thereafter, the great God cell phone official microblog bursts of two micro-blog, declared God F1 2G and God F1 Plus version straight down to 499, 399 Yuan, respectively, and great phones was in direct contrast with the red rice 2A.

Mobile phone, to 500 yuan in fighting mobile phone market?

Down to 399 God F1 Plus

https://www.youtube.com/watch?v=0tmZUXKJ6GU

A is the Overlord, a sniper who is ambitious, the two tit-for-tat, mobile phone prices plunging to below 500 Yuan, up to 399. From the perspective of both sales, 500 zhenjianduimaimang should not be a gimmick in the mobile phone market. Red rice 2A after announcing price cuts, is said to have sold more than 300,000 units in a single day. Great price, although no data are available, and there are many rumors, but at least 499 red rice 2A form opponents.

Millet in 500 Yuan, whatever strange cool sniper what would be the result of the market, in short, is currently the product structure in millet: "achieved by less than 500 Yuan to the full coverage of more than 200 products, 500 products has become a mainstream product. "If an odd cool can stick there might formed a line. This way, it puts pressure on other handset makers formed a. Pressure on brands is: Yes, there is the tiller? The pressure on second-tier brands and even fake brand is: is go on hard shoulder or exit?

Manufacturer is unlikely to ignore, some manufacturers to enter the market potential is very large. I never worry about 499 red rice 2A will have the possibility of losing money before it 599 priced far higher, after all, the core L1860C is millet's own products, of sorts. Then, as Huawei Technologies, with the advantage of hardware, do not seem to cost barrier to this market segment. Meizu, is trying to catch up with the brand, trying to reverse her manufacturers such as Lenovo, see 500 mobile phone market is booming to ignore it? It's unlikely. Such as zhongxing, even 599 yuan market wanted to give up, let alone 399 Yuan market. However, zhongxing development, current situation, give up 500 Yuan market relevance of this policy is really open to question. As for those second-tier brands and fake brand, but conscientious living, this piece of meat is not fat, and to a lot of hungry wolves, how it can be better!

Joy is the average consumer, with cheaper quality not bad phones, so why not?

Mobile phone, mobile phone market may be fighting to 500 Yuan. This situation goes, I guess 299, 199 Yuan's big Smartphone is not far away from us. Indeed, the ecological chain of Internet companies mature, mobile phone manufacturers free of charge to your phone is not impossible, as long as you don't kidnap users will do.

On in AWE I experienced the world s first eye tracking VR display

"Editor's note" this article from the code Nada feeds, following to the industry first-hand travel Doc – Daniel Oliver Kreylos records.

On in AWE, I experienced the world's first eye-tracking VR display

2013 I had participated in a world exhibition (Augmented World Expo,AWE), I was ganged up on AR the oceans. Now it is different! AWE started and UploadVR to host this Conference. But this time, I'll bring you some hands-on experience of VR display my records.

eMagin 2k×2k VR HMD

EMagin that head-mounted display devices are not yet named me to the main objective of this AWE. Before this there have been some views and details, but I have been declared suspicious 80 ° x80 ° viewing angle. And Oculus Rift, and HTC/Valve Vive or other similar head-mounted display devices, eMagin's head was based on OLED microdisplays (microdisplays are their core business), head-mounted display devices based on the micro display, including the eMagin Z800 3DVisor their launch, in terms of viewing angles are less than satisfactory, the General maximum of no more than 40 °. After all, the area only about a square centimeter size of a screen is enlarged to cover most of the Visual field, than required for the display of the zoom a few inches of optical lenses is much more complex.

On in AWE, I experienced the world's first eye-tracking VR display

Didn't think my suspicions are wrong, and eMagin with their argument a truism. I tried this, and ate breakfast with their Project Manager Dan Cui and a in-depth and friendly talks. So, details how? First and foremost is that this is just a very early prototype, not the development version, but not consumer products. At present it is heavy (close to 500 grams? ), Most of the weight is in the front part of any kind of sensor is not installed; there is no tie wraps; screen not the final form (details below). Dan mentioned that Developer Edition final release date, they wanted to be done in the fourth quarter of next year.

So, optical lens part of this equipment is very surprising, but its overall shape and design makes me want to wear in public. Of course, on the premise of its augmented reality mode.

It has a typical cyberpunk style.

We begin with the display system say. It is monocular 2kx2k OLED micro display panel (0.63 x0.63 ″), as well as extremely high pixel fill rate (no screen door effect). In the current prototype, run under the 60Hz of the screen (through an DP1.2 interface to connect to computer) full light mode. As far as Dan says, low light low light mode of screen time of 1 MS is immediately feasible, run under the 85Hz no need for improvements to the circuit, and in the current OLED screens used in 120Hz can be done.

This Panel's biggest problem is that every pixel of the screen and no blue sub-pixel. But I am sorry, I tried for the first time is not even see through, because the content is in a warm yellow-red in a virtual environment. And apparently this is not enough, but Dan guarantees full RGB panels are already in production, integration done immediately online. Will need to judge the quality of the screen, after all, the blue OLED pixels than red and green pixels produces a lot harder is a well known problem in the industry. Therefore, after the screen pixel layout Division may also vary, palpable screen resolution and pixel fill rate leads the curtain effect is likely to change, as is the popular Pentile arranged. But eMagin OLED is obvious at the professional level, I finished good.

The rest of the optical system is top notch.

Order triple lens system creates a relatively wide viewing angle: 80 ° x80 °, looks a bit smaller than the DK2, of course I hope to be able to have the opportunity to put together for direct comparison. Dan claims that in future versions of Visual angle can also increase a bit. Picture has a medium level of geometric distortion (demo software apparently don't have any pre-distortion correction), but I didn't find dispersion phenomenon, because even if there is, it is difficult to detect due to no blue.

Screen is always in focus, after all the physical pupil distance and focal length can be adjusted for each eye. Current prototypes and not through the inductor induction physical focal length values transmitted to the software, and this is much-needed! The focal length of the lens can only be adjusted when the mirror cover on the turn, more difficult. Yes, the lens and screen section to turn on, meaning that can be doubled up when you want to see the outside world.

But the biggest improvement is clearly part of the screen. Compared with the DK2 and GearVR, the resolution difference is obvious. Rift CV1 and Vive screen resolution is 1080x1200, assuming that 100 ° x100 ° viewing angle, the head of PPD (Pixels Per Degree) at 25, CV1 twice times over.

On in AWE, I experienced the world's first eye-tracking VR display

So, I was very excited to imagine the shine to the RGB, 85Hz low-light screen, internal or external location tracking sensor or LED, as well as improved industrial design (reduce the overall weight, improved weight distribution, head band, etc) after it. For the price, there is no any information, but Dan suggests that the original version at the consumer level range, once mass production, the final product is very competitive. So to speak, I can get this thing sooner would be willing to pay a lot of money, I have wanted to for several applications.

 castAR

On in AWE, I experienced the world's first eye-tracking VR display

I have also been lucky enough to try a castAR. I am quite curious about this thing has been, because around this topic and controversy. First thing to say is, "castAR" anomaly, called "castVR" was appropriate. It is to me, AR is seamlessly added to virtual goods in real-world environments, whether it is through video processing or transparent lenses. CastAR didn't use it in two ways: you need to put a retro-reflective panels placed in front of this thing obviously gets in the back of the Panel. Virtual goods is in the Panel and the space formed between the users. It belongs to the "fish tank" or "contains" VR, function and morphology is closer to CAVE or other screen and projection based VR (for example, Z-SPACE).

On in AWE, I experienced the world's first eye-tracking VR display

Of course, this is something in the text.

CastVRAR how to use it?

Well, in fact, pretty good. For the achievement of a few details before I was skeptical: stereo quality, tracking quality, brightness and viewing angles as well as interactive quality. Disney case

In front of my evaluation of these one by one, first briefly this stuff works, after all the way and Oculus Rift this head-mounted display devices are very different.

CastAR is a head-mounted, but not through the front screen to image, but in the use of his left eye left and right eye to the right of the small projection, retro-reflective materials on the front light, then it will reflect the light back to the consumer's eyes. Due to the projector and the position of the eyes very close, castAR does not need to know the location of retroreflective materials in advance to set up an appropriate projection matrix. After when combined with six degrees of freedom head tracking, castAR in users between the retro-reflective material and virtual objects form a very sound and healthy.

I worry about stereoscopic imaging quality, received information that may occur between the two eyes cross. But it turns out, castAR create an almost perfect stereo quality.

Retroreflective materials mainly back to the left eye left eye projection, projection mainly back to the right eye and right eye, but are limited by a real physical environment, as well as material properties, information impurities it is hard to avoid. But did not think castAR impurities using a polarizing filter to be further removed (just, retro-reflective material is metal, to maintain polarization), which create an almost perfect stereo quality.

Second problem is tracking quality.

CastAR uses optical tracking, based on two cameras on the head (do not know if using two cameras are a stereo camera), as well as an active infrared LED array. Basically, this is the RP DK2 optical tracking system. The tracking system was OK, but not great. When Caton (may be a few millimeters to one centimeter), delay is also more evident, leading to virtual objects drift and non-stable somewhere in space. Despite the infuriating, but it must be noted that this does not and closed VR cause dizziness, as virtual objects are only a small percentage of users to view. When I asked when a castAR said track is totally dependent on the optical, no inertial sensors and data fusion process. But even so, I've seen better optical track, after all the demo track small infrared array is large (approximately 5 ″ X5, ″).

A single input device over the track in the same way, two front-facing camera and infrared array. Caton despite input devices will be less obvious, but the viewing angle of the camera into the main issue: the clear stick only in a direction towards the infrared array tracks normal. It makes you want to pick up the virtual objects, flip them becomes difficult: a hands-on and they didn't respond. I have already used tracking handles, it's very uncomfortable. CastAR guide you through some demos aimed primarily at infrared array to avoid this, but for some common applications, by inertial sensors and data fusion for compensation should be able to track the quality of a great deal of improvement. Disney phone case

On the bright side, the brightness and contrast of the projector is pretty good. I thought the picture was bleak, however, as a result of retro-reflective materials, from the projection onto the back light in the eyes of users lost almost, in the bright light of virtual objects appear bright in the showroom is definitely good. But it's not perfect, has a problem is projector projection angle is smaller. CastAR viewing angle were two factors limit: one is the size of retroreflective materials (any consumer and retroreflective materials of objects invisible), the second is the maximum projection angle of the projector. After I asked the next, the data is castAR projection angle of 70 °, in actual use, though I'm not too concerned.

Finally, with regard to calibration, castAR presentation of the virtual handle and a practical handle is worse then a few feet.

This should not normally occur, especially a handle and an infrared head tracking is based on the same array. I don't know if this is due to the projection, after all, and users are not in the same position the eye, after far from the projected part of retroreflective object will have obvious bias. In this case, still needs to know the location of retroreflective sheets plane equations in order to set an appropriate projection of the variable arguments.

Generally speaking, CastAR and other screen-based VR system effect is something of a spell. It has a great stereo quality (better than LCD 3D TV), good brightness and contrast and then reply to reflector and are less expensive, can be based on the need for a large area covered. So you can do a similar CAVE system, entire rooms all fitted with retro-reflective material, holographic images of the room are free to watch, but would be limited to 70 ° angle projection. CastAR compared to other virtual reality system of the enclosing class, including the CAVE, greater benefit is the ability to allow a space to interact with many people. This is an extremely important point for joint work. Retroreflective materials can reduce the long projection system of mutual information between the pollution caused, and probably much cheaper than those screen-based system. If they can track parts, I'd buy buy buy.

FOVE

I just tried it, the so-called "world's first eye-tracking virtual reality head-mounted display devices (say no, you said" the first consumer-level virtual reality show "is more like it)" presentation. Two-minute presentations, I felt was in the midst of vision track is good enough, but at the edges was very inaccurate. Demo calibration is required before, you need to make your eyes look smaller. Formal presentation is a very intense shooting game, a bad screen resolution and quality of the evaluation itself.

On in AWE, I experienced the world's first eye-tracking VR display

I noticed a strange effect: when I looked down to see my enemies, aimed shot completely disabled. May be gaming your own 3D light calculation bug.

 SMI eye-tracking based on DK2/AltspaceVR

I also tried another world's first eye-tracking in virtual reality: SMI eye-tracking based on Rift DK2. I've tried SMI eye-tracking based on Rift DK1. The new look a little better: you no longer need to cut a rectangular hole in the lens; new track behind the camera lens, not blocking anything. From a functional point of view, rather than the previous edition and no progress. Even after a complete calibration, I aimed at the direction of and tracking results are biased. One of the shows, I only have to use objects on to the field after the Central track, then make eye-tracking itself is meaningless.

Of course, it could be because I am wearing contact lenses. SMI tracks will take into account the user's eye and eye cornea and contact lenses will change slightly when I looked around my cornea, may cause deviation. But either way, these need to be mentioned. I guess when the VR for sale contact lenses would lead to another trend.

I wish FOVE of SMI and eye tracking accuracy compared FOVE shows makes it difficult for us to do (exactly how big those objects hits area? ) This. Who only can get the FOVE developer version to see.

I would also like to briefly mention AltspaceVR eye tracking integration. It has two parts: navigation and interactivity based on aiming and centering objects or locations, and user virtual eye animation can make user eye and blinking on a little cute robot avatar is mapped to AltspaceVR. Behind this part is actually doing quite ordinary, blinking monitor can only occasionally be monitored. May this new increase in eye tracking needs to be improved, but is an additional window.

Wearality Sky Lenses

This is the second time I tried after the SVVR '15 Expo Wearality 150 ° viewing angle of the lens. This time I have the chance to scrutinize the lenses. VR viewing angles exactly how should we measure it? In General is not easy, but Wearality Sky open design makes measurement much easier. When you put on the head after the show, I can see the real world from under the lens.

On in AWE, I experienced the world's first eye-tracking VR display

After wearing, I adjust their position before the left and right edges of the lens and aligned to the left and right edge of the table, and then see about three feet away from the table, table about six feet wide, so a conversion of Visual angle is 90 °, instead of 150 °. When I asked the people who give us experience this situation, he said 150 ° need for larger screen phones. I don't have to measure the use of the mobile phone, but it seems larger than the Samsung S5, is about 5.5 ' look.

Disney phone case

Wearality's Web site did not mention the viewing angle is based on screen size, although obviously you should know, you somehow have to provide a list of viewing angles/sizes as well. And give us experience are also very happy to continue to let everyone look at 150 ° head, even as he told me this number only for larger screen phones. What was that for?

https://www.youtube.com/watch?v=qk3Uspk6eAU

Then I saw a demonstration can Wearality by adding different sized black border to the rendered image to switch between different viewing angles, but this will allow them to use small size mobile phone adapter lenses and said she has a large viewing angle of more untenable.

Gear VR gave me the feeling is similar to popular smart watch, VR equipment there is no ability to completely replace other electronic equipment, especially Gear VR itself also needs to rely on a Samsung Smartphone, and if it is in use, there is an incoming call, SMS or email, users will also need to answer phone out from Gear VR treatment.

OK Google Now the science behind how dark

"Editor's note" the writer @ Chen Cun, Cambridge University natural language processing (NLP) master of group. In machine learning, semantic analysis engineer.

OK,Google Now the science behind how dark?

Not long ago, Google announced a reorganization of the Android business executives, Google Senior Vice President sangdaer·pichayi became the new CEO of Google. This change seems to have caused some dissatisfaction with Google Now the development team, lead to full separation (also said key members of release), Google Now merged into Search groups. Google is Now the Android platform to counter Apple's Siri, Microsoft Cortana's voice Assistant. So what is Google Now? It contains what technology Google black?

What is Google Now Cath Kidston iPhone 6 cases

Although this article talking about the broad set of App Google voice search is Now integrated, but Google Now more precisely defined narrowly, is Google on the mobile phone application Now open, appear on the first screen of the intelligent recommendation cards, at the right time to give you the right information, such as weather, news. Relative to the active input in Google search input box you want to find something, Google will Now "smart" to push the information you need in front of you.

So often Now referred to as Google Google's smart push technology.

Such as author when in a foreign country, can enjoy the convenience of Google Now. For example through Booking.com (similar to c) book the hotel, or kayak.com (like go) ticket confirmation email will be sent to my Gmail mailbox. Google will be "smart" analysis (peep) mail these trips, and a few hours before the flight about to take off your flight details and Terminal and gate information. When you arrive in a new city, and automatically eject you designed navigation routes, and contact phone number and other information. When traveling abroad, Google Now will automatically pop up the local currency, as well as the country. It will also remember your home carefully and position of the company, reminding you to go home on time traffic during off hours, and not smart enough to understand that you have to work late tonight!

Here say that the birth of Google Now

Google Now, is the legendary product of Google 20% Project. Baris Gultekin Google engineers in 2010 when rich sensors on the personal interest in using cell phones to do some interesting things, the idea coincides with then-head of the Google Map of Andrew Kirmse. Two people in their spare time to build a prototype and show time in MUI Marissa Mayer of Google.

OK,Google Now the science behind how dark?

Supported by the MUI, the team was growing, and was one of the users commuting time prediction and the integration of Google Calendar events. As it happens is that at the beginning of 2012, Larry Page requires Android and Search teams to build a similar thing. Support of the Android leader Andy Rubin, the two men joined the Android team, get a lot of design resources, and published for the first time in the 2012 Google IO Google Now.

After so many years of development, Google Now has now been integrated into Google search App.

Recently a foreign science and technology Web site also reported rumors that Google Now team, said to be members of full separation, also linked to the recent Google schema change, conspiracy theories of meaning. Some key members leaving anything, but this happened as early as a few months ago, perfectly normal personnel changes.

Google Now itself as an excellent product, from the Android team into the Search group, from a technical point of view, big Search group can get additional technical resources, early completion of the smart Google of this great goal is good, this is obviously good news!

Although the App interface is simple, just a search box and a card inside the technology won't be easy.

Introducing special Google Now recommended cards, we see Google Now with this little app, and contains a lot of Google's black technology: Smart recommends (Google Now card), hot words awaken (OK Google), voice recognition and semantic analysis.

First a little bit about intelligent recommendation

Recommended principles are "Just right information at right time", that is the right time to recommend the appropriate information. How to know what users really want, rather than machines gave that needs to handle. Although the statistical machine learning has been applied on a large scale in industry in recent years, but although the context of the unknown user information in all aspects of life, be advanced machine learning algorithms, smart recommendation cannot be made too, so companies using a combination of rules + machine learning strategies.

It appears from the existing product, Google Now recommend things are quite conservative.

Google can you stay in a place often guess at your home and work location, and traffic conditions in specified time automatically reminds you to go home every day.  Cath Kidston iPhone 6 Case

Mentioned earlier, travel message cards, hotel cards, foreign travel exchange rates and country time cards, and so on. Recommendation algorithm how much difficulty is not high, but Google can collect as much as possible to the user's lifestyle information in dribs and drabs and through thoughtful rules, do not bother to recommend to you. In other countries, because the message high penetration, Google with Gmail (by the way, Gmail with Google Now is born that year, and was born of the legendary 20% project), Google now,Google has its geographical and human.

Hot words awaken

Google Now the main interface of the software, on a cell phone call with a "OK Google", you accept user automatic speech recognition voice queries.

OK,Google Now the science behind how dark?

Hot words awaken as the key to start voice recognition, is designed to accept user with power consumption as low as possible awakening.

Because of the need to continue to open the microphone, operating on the audio input, the CPU has not been dormant, will seriously affect the already tense cell phone battery life.

Words awaken on a cell phone in order to maintain high standards, focus of the need to take into account, in addition to accuracy (user name is you can immediately respond, user is not called when you don't listen to the right), as well as energy consumption. Hot word wake not need like General voice recognition as recognition kaleidoscope of natural language, it as long as recognition "OK Google" this fixed of Word, so in algorithm aspects also without to used complex of traditional voice recognition, abandoned tall Shang of various HMM, and language model, with simple directly of classification of method in user entered voice flow in the looking for "OK Google" this several Word, simple but easy.

Of course, there is an exception, Moto x just came out a few years ago, is a 24-hour wake full voice, they have 2 low-power chips, specifically waiting for the user to input voice commands.

Speech recognition, needless to say, Google's strengths

A few years ago Microsoft research a dissertation based on deep learning applied to speech recognition, definition of algorithm accuracy beyond the traditional speech recognition based on HMM-GMM. But Google lead its industrialization, and apply to that year's voice search product. DNN on the original audio data directly to speech recognition, and require a lot of training data, neural network to train a large number of parameters, so the hardware requirements are very high, this is Google's strengths.

After years of accumulation, and Google's speech recognition has begun to take shape. Noteworthy is that as a competitor of Google Now Siri,Siri has been using the nuance of speech recognition technology (nuance is the world's largest provider of speech recognition, can be understood as the fly in China), while Apple also reported some time ago to set up his own message of the speech recognition team.

The semantic recognition

Through the Google search box above Now, you can ask some questions look very cool.

Some of daily life information queries, such as New York, flights to San Francisco, such as the next 3 days the weather in Beijing, Tokyo time. This question-and-answer system involving all aspects of natural language processing, it is very difficult.

Although academically, NLP (natural language processing) in a variety of areas, such as parsing, entity recognition, after decades of effort, has made more than 90% of accuracy. But in the actual context, users more diverse colloquial expression, ambiguity, and academics are often used for evaluating system set of language tests varies widely.

And, question-and-answer system is the product of several NLP system into line, such as speech analysis output as an input to parse, parse input output may be recognized as an entity. In such a system, errors will be propagated to the line of the earlier steps, and was magnified.

OK,Google Now the science behind how dark?

Therefore small errors on a single subsystem, will eventually be enlarged, understanding of the serious impact on end users ' queries.

General question-and-answer systems are specifically optimized for current field, study what are the most frequently asked questions, and we have relied on the rule (even a regular expression) and strengthening user guide, reducing the ambiguity of natural language.

Google Now voice search also supports Wikipedia issues, such as current United States President who is, how much is the height of the Himalayas, or how large is the population of China.

Google after all is search origin, sat hold whole Internet of information, tens of thousands of of page in the has contains has "Obama is United States President", "China of population is 1.3 billion" such of statement, for Google for, problem will simplified into how match user of problem to tens of thousands of page in the of a a sentence words, and just to out Top dozens of of match page, this in screen small of phone Shang, and even watches Shang on user experience of effect vital.

Academic general practice is to first identify users are asked which type of problem (What? When? Which? Where? Etc.), and then using information retrieval strategy first filtered in thousands of Web pages and user issues most relevant to candidates page, and according to the type of problem, these candidate pages to pick out the most direct statement that answer user questions. Win Jeopardy! (Can be understood as the old quiz so quiz shows) IBM Watson of the human champion system also uses a similar design. This method ensures the Automation methods to improve the coverage of the problem of non-human, rather like a fruit needs to recruit a lot of problem edits to deal with more and more enthusiastic masses to the relentless teasing of Siri.

Google recently, semantic analysis, mapping knowledge devoted a lot of energy, we can Google Now as well as in general search to see the integration of such technologies.

So, Google Now merged into large groups of Search and get more technical support is definitely a big improvement!

Microsoft Wireless charging pad luminous and will remind you to charge mobile

Microsoft Wireless charging pad: luminous, and will remind you to charge mobile phones

There are various manufacturers in the development of wireless-charging devices, such as the Tylt charger, although it seems like a black plate, but functional and have a good compatibility. Microsoft has now joined the ranks, and came out with a more "shine" products. This Qi-based wireless charging standard Nokia charging plate, not only can charge Smartphone, also white, green, orange light.

When a Lumia Smartphone when it is placed into the plastic plate, it will immediately glow, instantly brighten your table. Due to the intensity of light is very large, if work and rest are disturbed, can make between three brightness adjustment. When night falls, you can also turn the lights off completely, so it can not be frequent interference of neon. Marc Jacobs Galaxy S4 Cases

There is no doubt that these options only Windows Phone can use. Although theoretically, this pad can charge any device that supports the Qi standard, including the Nexus 6, night mode, and other settings can be set through the menu of the Windows Phone.

In addition, you can also make the charger Board to push app with different Flash modes remind or missed calls, but unfortunately couldn't make it so that each app has a different display mode.

If there is a Windows Phone and device through a Bluetooth connection, when it is running out of power when charging light will prompts signals, remind you of the charges as soon as possible.

This model DT-903 charger Board has obtained from the Microsoft store shelves, priced at $ 59.99, it is equipped with a common USB interface, so I plug it into the computer's USB interface you can recharge yourself.

Maybe HTC in the Android camp has typical of industrial design, coupled with the previous generation M8 public expectations have been raised too high, so at the press conference following the end of routine upgrades of the M9 and not so strong repercussions. Discussion on the M9, consumer channel is highly concentrated on the legendary "three-jaw" and "around the Israeli-Palestinian" "Wu Chin" ... Marc Jacobs Galaxy S4 Case
