Samsung Galaxy S4

Samsung Galaxy S4 is a 4.2.2 Android Jelly  Bean operating system mobile uses the vibrant touch wiz user interface has been able to generate good demand. It has a full HD super ambled at a pixel resolution of 1920 by 1080 which gives a pixel density of 441 pixel per inches protected by Corning Gorilla glass. It has 13 megapixel duel camera, sound and shoot mode and dram shot. It has also Air Gesture, Air View, Group Play, etc.
The Korean company had earlier launched a 0 percent 12 month EMI scheme for the Galaxy S4. Now the company has launched an exchange offer along with a lot of freebies with the device. The new Galaxy S4 doubles down on the formula of its predecessor, slim package, big screen and tons of features.
Hardware:
Galaxy S4 next to a Galaxy S III and you'd be hard pressed to pick them apart-until you turn them on. 5 inch screen on the S 4 is even larger than the S III. It is nearly on par with the extraordinary crisp screen on the HTC one but far brighter and with better contrast and color saturation.
It has a plastic back, a single hard home key on the bottom and an illuminated menu and back capacitive keys that disappear when not in use. Samsung is sticking with a designed that has worded for them and company executives claim that the plastic back allows them and their customers greater flexibility for removable batteries and memory and accessories such as the S-View cover, which serves as a replacement for the original back panel with an integrated screen protector,thus shielding the front glass without significantly increasing the thickness of the device. The S III had a similar cover but this new one has a transparent panel that allows you to see information such as the time, the number of messages you have and incoming call.
Samsung has not at all abandoned the race for more megapixels. The Galaxy S 4's camera has a 13megapixel sensor, which really does take some stunning still shots.
Samsung also has the other must have halo feature of 2013: an infrared blaster that allows it to function as a remote control for your television and other AV gear.
Software:
Galaxy S 4 keeps with its successful software strategy: Pack in more feature than any customer could discover in a human lifetime. It has 13 mode camera app, including automatic animated GIFs that let you select the parts of the picture that are in motion, a drama mode that composes multiple action shots into one image and an eraser mode that turns multiple exposures image, removing anyone who is in motion.
Samsung Galaxy S4 has Air Gesture function uses infrared sensors that can detect sweeping gestures of your hands a few inches above the screen. You can use these to answer the phone, move between photos in the gallery or move up and down on a web page. Samsung has used  this type of interaction in its Galaxy Note series of tablets and phablets but those devices used an electromagnetic resonance pen.  If you look away from a playing video, that video is paused. The screen will stay on as long as you are looking at it. Web pages will scroll up and down in response to the tilt of your head. Samsung's new features are in consistently applied and after a few days you  find  yourself turning  a lot of it off.
When Samsung introduced  its phone to phone content  sharing features, called Group Play, in the Galaxy S III, we loved the idea but thought it was a bit strange to presume all your friends would have Samsung phone. Samsung has expanded Group Play to support collaboration on Power Point presentations, PDF and Word document and even games.
Samsung also invested time and effort in cleaning  up and reorganizing its touch wiz user interface that sits atop Android Jelly Bean. The most immediately useful change is an expanded set of instant setting icons in the drop-down notification panel. Now you can easily turn on off without digging  through the settings menu.
Conclusion
The Galaxy S 4 can do things out of the box that no other phone can do. But it's worth nothing that much of the functionality built into the S 4 can be added to other smartphones through apps. Samsung can continue cramming more features into its next generation devices.
Galaxy S4 is a satisfying  device for using. The size and clarity of the screen alone give it  uncommon than the other smartphone.

Belkin Plus 7-port USB2.0 Hub

If there’s one universal truth to personal computers, that you can never have enough  USB ports. Doubly so when the front USB ports o your computer suddenly crash from overuse.  That’s why today we bring you an in-depth review of Belkin’s  7port USB 2.0 Hub.

Hub Design

The Belkin Plus Hub bears a rather unique design. Measuring 6”*3.5”, the hub is rather thin but a bit on the long side due to the USB ports being arranged horizontally instead of vertically. The end result is slightly more desk space being used but when combined with the slim profile it makes the hub much more manageable when it’s being stacked. You’ll notice that in the center of the hub next to the two top-mounted USB ports is a small rectangular hole, meant for stacking on top of another 7 port plus hub’s two USB ports for a snug fit. The hole is surrounded by a large section of blue molded rubber that contrasts with the hard white plastic that makes up the rest of the hub.

If the hub isn’t being stacked however, the hole can make the overall appearance somewhat awkward. The molded plastic turns into a cable management clip on the right side of the hub for keeping your PDA and iPod data cable handy.

Hub Performance

As a technology enthusiast, gamer and over clocker, I have never been one to go easy on my hardware. I expect things to run at full capacity without any crashes of hiccups. thankfully Belkin passed with flying colors. The Plus USB was fully loaded with managing Logitech G15 gaming keyboard with a gaming mouse plugged into the keyboard, handling the video stream from USB monitor, playing back the video from USB 2.0 web camera, synchronizing iPod while charging it as well as cell phone. The Plus Hub managed to get a little warm throughout the ordeal, but not nearly as hot as a laptop or hard drive can get. This device include a USB sound card with playback controls, an MP3 player, a webcam, a game pad and two external hard drives. Using 2.0 Hub introduced no slow-downs when the drive was the only device connected, peaking at 23.5MBps. considering the hub must maintain internal communication between 7 devices including a game pad that uses an interrupt protocol, these results are actually pretty.

Lenovo ThinkPad x220 Review

Lenovo's Think Pad x200 series has a long history of combining lightweight portability,
epic battery life and uncompromising performance.
Design:
Comparing favorably to last year's Think pad x201 and the HP Elite book 2740p. However, the 13 inch Mac Book Air is much lighter and thinner. The standard six- cell battery takes 1 off the depth of the notebook and 0.2 pounds off its weight. The optional battery slice, which attaches bottom of the system, adds 0.6 inches of thickness and 105 pounds of weight. 
Think pad aesthetic complete with a rubberized lid and a metallic Lenovo logo and raven black sides. Perhaps the most noteworthy departure from other high end Thikpads is the absence of a latch on the lid.
Keyboard and Touchpad

Think Pad x220 keyboard offers the kind of amazing tactile feedback and concave shaped keys that allow touch typists to input quickly and accurately. The keyboard also has a full array of extended keys such as Scroll  Lock and Pause for  users who need them. Unfortunately while the keyboard itself feels great, the short 2.5 inch palm rest will leave many users wrists hanging over its edge, which can be uncomfortable and  can place added strain on the shoulders and wrists.

Who prefer touch pad will appreciate the x220’s 3*1.75 inch textured click pad. Though we have been critical of previous button less touchpad because they were jumpy, the x220 synaptic powered pad was accurate and comfortable to use.

Display and Audio

12.5 inch 1366*768 matte display on the think pad x220 offers bright, sharp images and amazingly wide viewing angles. We were able to watch video without noticing a significant loss of color fidelity. Our only complaint is that Lenovo chose to go with a 16:9 ratio after offering 16:10, 1280*800 displays on the Think pad x201.

Ports and Webcam

For a notebook, x220 has plenty of port. On the right side are SD card reader. An audio jack and a powered USB connection that can charge devices even when the notebook is off. On the left are VGA port, display port, two USB ports and an express card.

The 720p webcam, which support Skype HD calls, provided crisp but washed out image. Under bright overhead lighting, details were sharper, but had way too high of white balance at both auto modes. The webcam even stopped working and displayed a black block instead of an image. This problem persisted until we finally powered of the system completely for a few seconds before booting again.

Graphics

It comes with Intel HD Graphics chip which is good enough for playing videos and performing most tasks, though you can forget about serious gaming. On 3D Mark06,which measures overall graphics prowess, the x220 scored a respectable 3494, which is more than double the category average of 1611 and far better than the 1900 that last year’s. However, the 13 inch Mac book air has a discrete Nvidia GPU, managed 4611.

Verdict

The Think pad x220, Lenovo has combined epic battery life, strong performance, bright screen, responsive keyboard and powerful security features to make one of the world best ultraportable even better. User who want an even lighter notebook with a better screen and larger palm rest might prefer the 13 inch Mac Book Air. If you want something that packs a ton of power into a tiny package, the x220 is an best choice.

Logitech G13

Logitech G13 is a separate gaming keypad that give you all of your WASD controls,
programmable macro keys and quick-fire commands, without the bulk of a keyboard and with the added comfort of a use-specific design. The whole device of this keypad measures 1.3 by 7-10 inches and weighs 1.3 pounds. With   rubber feet, the G13 is very stable, so it would not slide or tip from the frantic pounding it might take in the midst of a match. It connects through a wired USB 2.0 connection and the 7 foot cable should be more than enough, even if you need to snake it down and around and behind to plug into an out of the way CPU tower. The keypad portion of the G13is well designed with 22 programmable macro keys arranged so that your fingers will naturally fall into the correct playing position. In addition to the sculpted key-caps, the entire keypad is curved to match the arc of relaxed fingers. Following the curved contours of the keypad is built in wrist and palm rest. Coated with a textured soft-touch rubber surface, the palm rest should be comfortable during longer gaming sessions and stave off the carpal tunnel that regular keyboards can inflict on heavy users. The joystick may just what you've been looking for, but never could manage the complex task of simultaneously using the joystick with thumb and the keypad with fingers.
G13  has a small  LCD display that is used for on the fly macro recording, monitoring system data, including CPU and RAM usage. you can use it as an RSS reader.  You have a back light on/off button and mode button for the LCD. Three button are for saved programmable key maps letting you save three separate sets of functions for all 22 keys and the fourth is a Macro Record button.
Pros
Programmable button keypad with swappable maps and profiles, on-board memory, extra long cable.
Labor intensive setup, not plug and play. Click-able joystick is difficult to click.
Bottom line
The Logitech G13 advanced game pad is definitely a niche product but with  a comfortable design and wide array of features.

Alienware M17X Review

Alien ware is back with a bang, with a threefold attack on the PC gaming arena. Along with the M14x and the M18x, the M17x has had a third generation Intel flavored refresh for 2012. The alien ware M17x isn't any different to the model that wowed us last year. The exciting new additions are all buried deep within the M17 is brutish chassis. The model we reviewed packed an i7-3610QM processor. Which can be pumped full of Intel Turbo boost steroids to achieve a top speed of 3.3GHz.

Hardware:
The impressive spec sheet doesn't end there, you can select up to 32GB RAM, the 17.3 inch display is of the full HD 1080p variety 2.1 megapixel webcam and has a slot loading optical drive on the side.
You might think that all of this rugged power may result in an explosion of noise, fan activity and a heat overload as with previous Alienware notebooks. This is thanks to its large heat sinks and dual rear exhausts, which provide dedicated cooling for all threads and cores of  both the CPU.Equally, if you want your M17x flashing bright red neon lights at you continuously , like a panicking air traffic control warning system, then that's an option too. The Keyboard keys color you choose to have emitting from them, are soft to the touch with a comforting rubber like bounce which makes them not only great for gaming but also for more day to day tasks such as browsing the web. The track-pad, which is offset to the left, has rubberized finish and you will hear not a peep from either of its buttons, such is the soft travel.

Heavy load:
The M17x is not travel friendly, the improved battery life of 133 minutes under stress.You will need a strong back to handle its weight load. Back to the plus points though and as you'd expect with the hardcore engine room, the Alienware M17x had little trouble dealing with any task that we threw its way. Recent game titles caused it no signs of despair and high resolution photo editing was done with hardly any fuss. You can configure the hard drive setup on your own Alienware model pretty much any way that you choose.
As well as Wi-Fi and Bluetooth 4.0, you have also got access to four USB 3.0oirts, HDMI 1.4port, mini-display port, Ethernet action, SD card reader, VGA socket, optical digital output, separate headphone and microphone jacks. The Alienware M17x is a significant improvement to what was already a brilliant machine. Its bulky frame and ostentatious exterior may make the M17x a specialist laptop but within the 17 inch gaming note book market.

Beyond The Touchscreen: Projecting The Future

Imagine a cookie that changes flavor on the spot or a furry computer display that your stroke when you miss your cat. It might sound like fantasy but visitors to the SIGGRAPH computer graphics and animation conference in Los Angeles. This month have experienced nothing less from the new technologies on display.  Here, New scientist brings you some of the extraordinary computer displays on show a preview of how we could interact with computers in the future.

Future on display: the flavor changing cookie

Imagine you could dip your hand in the cookie jar and be guaranteed to pull out whatever flavor you feel like. For cookie lovers visiting the SIGGRAPH computer graphics and animation conference in Los Angeles, this dream was turned into reality.

We are all used to seeing, hearing and increasingly, touching computer displays but there has been little research into how computers can successfully stimulate taste. Part of the problem is that taste is generated by a combination of factors working together, including vision, smell and memories. The university of Tokyo in Japan decided to tackle this problem with a display that exploits several senses. Their testbed? The humble cookie. The device is worn over the users head and can transform the taste of plain cookie to any of seven flavors. It combines augmented reality technology with smells released by an air pump to trick the users senses.

Follow the cookie
To create the effect, the team branded a plain cookie with a distinct logo that the headset track via a built in camera. An air pump sprays out the smell of the chosen cookie, increasing its concentration as the system sees the cookie approaching the wearers nose
Meanwhile a visual display in the headset shows an image of the chosen cookie, suggesting the correct texture for that flavor. That combination of smell and visual texture combine to fool the users sense of taste into thinking they are eating a flavored cookie instead of the plain one.

Future on display: Desk lamp turns table top into 3D

Switching on a lamp is all it takes to turn a table top into an interactive map with this clever display, on show at the SIGGRAPH computer graphics and animation conference in Los Angeles. Multi touch table top displays project content through glass and respond to touch imagine a table sized smartphone screen.
But  the National Taiwan University in Taipei wanted to make these types of screens more appealing for multiple users. The idea is that several people could look at the same images and get more information about the areas that interest them. Users viewing an image such as a map projected onto a table top display can zoom in on specific areas seeing street names for example simply by positioning the lamp device over them.
The Lamp is fitted with infrared cameras and can use the hidden markers to compute its position tn three dimensions. It then uses this information to control the projection of high res images onto the correct place on the table top.

Window on 3d

The team have also created a tablet computer which lets viewers see a two dimensional scene in 3d. If you hold the computer over the area of the map you are interested in 3d view of that area will appear on the screen.
The lamp also comes in a handheld flashlight design which Chan thinks could be used with high res scans of paintings in museums. Using the tablet computer to show up areas of a 3D map would allow several users, each with their own tablet to examine and discuss the map at once. This could be useful for the military, when examining a map of unfamiliar territory and discussing strategy.

Future on display: Technology you will want to stroke

Whatever you might expect from the latest computer technology, fur is unlikely to be one of them.
An unusual display at the SIGGRAPH computer graphics and animation conference in Los Angele's this month is all about the senses and uses optical fiber to create a surface that feels furry.
Humans are naturally inclined to stroke furry objects, say Kosude Nakajima from Osaka University, japan and colleagues. so, they say , we will need no instructions to interact with a furry display. The surface of the Fusa2 display is covered with the front of the display, they begin to touch its surface without any suggestions and instructions.

When you stroke the display, it changes color, creation stroke marks. In order to detect the touched area, the fiber optics surface has many infrared LED,Explain Itoh. Underneath the display, half the fibers lead camera and the other half to projector. when a hand strode the fibers, the infrared radiation is reflected and travels down the fibers to the camera.
He believes there are practical applications for a screen that users intuitively want to stroke. Because people are naturally drawn to it.

Future on display: 3D touchscreens made for two
Two of today's most popular technologies, 3D imagery and multi-touch screens, are brought together for the first time in this display.

The images in 3D movies seem to be coming out at you, but trying to touch them would would ruin the illusion, as your hand will pass straight through. Now Jean-Baptiste de la Riviere and colleagues fro Immersion, a visual simulation company based in Bordeaux , France, have at last managed to combine the two technologies into an interactive 3D table-top display.
Better still, two users viewing the same model city at the same time from different sides of the table could each see the 3D effect with the correct perspective for their position. That's because the glasses are wired to position and orientation sensors that track the wearer's gaze and the system uses this information to alter the image accordingly in real time for each user.
users can also interact with the display when they touch it, to zoom in or rotate.
The system makes images that seem to rise above it when a person is simply looking at it. The display knows when a hand is coming near it thanks to infrared sensors.
