Two sizes are available. A smaller 13 inch version weighs in at just three pounds. The 15 inch version weighs just four pounds.

Some fans have been clamoring for a touch screen application from Apple, and the new Pro delivers but in a different way.

Apple has created The Touch Bar. It replaces the function keys that have long occupied the top of the keyboard. This can provide automatic adjustments for system controls like volume and brightness. It provides interactive ways to adjust or browse through content and type with features like emoji and predictive text.

Speed has also been improved. The Pro is said to deliver graphics at a rate 130% faster than before.

The retina display has become an Apple standard and some new enhancements provide colors even more vibrant than before. Brightness is increased by 67 per cent.

Audio is enhanced with totally redesigned speakers. Apple promises 58% more volume and two and a half times more bass. The Pro will enable you to mix a track on the fly, edit video on location, and enjoy a movie as you head to your destination.

For the first time Touch ID is available on a Mac. This enables instant access to logins and fast, secure online purchases with Apple Pay.

The MacBook Pro has a better feel. The keyboard is more comfortable and responsive. The Force Touch Trackpad has been enlarged so your fingers have a little more room to work with.

Those needing extensive business applications will find four USB-C/Thunderbolt 3 ports included on both sized devices.

You will need a new Thunderbolt 3 adapter if you wish to use a hard drive. Once connected, you can integrate data transfer, charging, and video output in a single connector, delivering up to 40 Gbps of throughput for twice the bandwidth of Thunderbolt 2.

The device offers 3.8 GHz with Turbo Boost Processing. Users can expect up to 10 hours of battery life.

And, of course, users will get the MacOS operating system. You can connect with all the Apple apps, iCloud, iPhone 7, Apple Watch and other features.

Prices tend to run to the high-end. They start around $1,500 for the 13 inch model with 256 GB of storage and no Touch Bar or Touch ID. The “Touch” features begin at the mid-level model which runs $1,800. Add more storage to 512 GB and the price hits $2,000.

The 15 inch has similar price elevations. The bare bones model without the Touches runs $2,000. The mid and high-end models with both Touches start at $2,400 for the 256 GB model and hit $2,800 for 512 GBs of storage.

Overall the MacBook Pro has formidable computing power, superb build quality and the long battery life you would expect.

It is an attractive replacement for those seeking a Mac quality high-end desk top in a laptop. Though it comes at a handsome price.

The Acer neoTouch S200(F1)– running on the fastest processor (1 GHz) and the latest operating system from Windows (Windows Mobile 6.5 Professional)– is one of the fastest PDA in India right now. Even though the phone runs on a 1 GHz processor, it doesn’t consume much power, due to its power saving technology. The F1 comes with a large 3.8-inch WVGA touchscreen, which gives crisp and sharp display. The neoTouch comes with a slate-like form factor it has a large screen and slim size (12 mm) and a very clean design.

On the top of the large touchscreen is the LED indicator, the earpiece and the proximity sensor. The phone lacks a secondary camera. At the bottom of the screen are four flat feather touch keys with haptic feedback — calling, home, back, and call end. The chrome finish running around the edges gives a bold look to the device. On the left is the power/standby key. The bottom has a mini USB port for syncing and charging. On the right is the volume rocker, a small reset hole and camera key. The 3.5 mm audio port is on the top.

The back cover has a glossy finish but is a fingerprint magnet. The back panel has the 5.0-megapixel camera with LED flash and the loudspeaker grill. Inside the back cover are the battery, SIM card and a memory card slots. The neoTouch comes with the latest Acer UI 3.0. This UI has masked the original Windows interface giving it a smooth feel.

The F1 is bundled with Microsoft Office version 6.5. The complete office suite includes Excel Mobile, PowerPoint Mobile, Word Mobile and One Note Mobile. Files can be saved in di fferent formats like plain text, word document, word template, rich text format and docx format. You can open, edit and create documents. The screen touch QWERTY is smooth and sensitive and even though the stylus is provided it is hardly required unless you have huge fingers. On the downside, the phone does not have a PDF viewer pre-installed. Setting up and using E-mail on the phone was quick and easy. On the other hand we had to callibrate the device twice to get the right touch response. Once done, the phone worked smoothly.

The Acer neoTouch S200 is a 3G phone, which comes with Wi-Fi, GPRS, EDGE and Bluetooth v2.1 with A2DP. FM radio comes with RDS. Wi-Fi has dual channel support — 802.11b/g, which gives decent speed and a great performance. Browsing moves to a higher level with the F1 with good browsing speed. For GPS, the device comes with Google Maps which are accurate just like all the other such apps from Google. The inbuilt app — Join latitude – tells your friends where you are on the maps once you sign into the app using your Gmail account. The F1 has pre-loaded apps like e-blogger, Flickr, YouTube and Facebook apps for interesting and lively connectivity.

Overall, the neoTouch is a very decent phone, which comes with a 5.0-megapixel camera and 3G but lacks video conferencing. The rest of the features are high on our most wanted list.

If you do not mind this small flaw, you can have a try!

Watches are all time favorites amongst all age groups. These have become indispensable as accessories. They are not only fashionable but also useful. Pocket watches with chains were predecessors of wrist watches which came into vogue in 1920s. Since then, the watch industry has grown by leaps and bounds both in terms of volume and technology. Earlier, there were only mechanical watches. Soon, these were replaced by quartz and digital watches.

Watches are accessories or gadgets that intrigue us as early as in our childhoods. I remember when I was a kid I used to look at my grandfather’s pocket watch and wish I could own it someday. Today, while browsing the internet I came across a wide range of pocket watches which were very affordable at $ 2.91. The one which caught my attention was the Antique hollow pattern brass quartz pocket watch. It also has a chain belt. It is reasonably priced at $3.90. It has an antique pattern with scratch resistant stainless case. It is exquisitely engraved that gives it a classy look. The diameter of the watch is 38 mm approximately. This looked to be a very good gifting option for your father or grandfather.

You can find watches on the internet which suit everyone in terms of design, price, gender, and workmanship. There are excellent silicone sports bracelet watches. These are unisex, healthy, fashionable, and water-resistant. They are available in vibrant colors which never fade even after regular use. This piece is available for $ 0.96 approximately.

If you are searching for something which is elegant then you must definitely have a look at the Curren high quality Rhinestone watch. It is an elegant quartz movement with calendar dial. It is golden in color with rhinestones embedded on the 3cm-dial. It has a stainless steel band and is priced at $ 13.11 approximately. The watch is ideal for formal wear.

Nowadays, LED watches have become a rage. I am particularly impressed by the unisex touch bright blue LED watch. It has a modern design with a touch screen which when touched gently displays the time. It is an electronic watch with a watch face diameter of 4.3 cm approximately. It is available in cool colors like pink, white, blue, red, and orange. It is moderately priced at $9.14 approximately.

A watch is one such accessory which is loved by both men and women. It is not only a style statement but also an incredible gadget.

Data recovery is considered as a standard procedure for most devices. In most cases there is always a storage device like a hard drive or a memory card that needs to be recovered. This is different in case of an iPod. As an iPod does not make use of a memory card, recovery needs to be done on the hard drive that has been designed for the iPod. The iPod has a unique hard disk which needs to be accessed for data retrieval. There are also some iPod models that do not allow data recovery software to access the hard disk and hence make data recovery extremely difficult.

The iPod is a multipurpose, which is not only used as a music player, video player or photo viewer, but it is a multipurpose device that is even capable of acting as a storage device. Due to this multipurpose nature of the iPod, the users prefer to carry it around and use it not only for listening to music, but also for viewing photos and videos. The fact that their entry directly marked the exit of the walkman goes onto show the popularity that this device has managed to gain in a few years.

The iPod comes in a variety of models right from the small sized iPod Shuffle, to the recently released iPod Touch which comes with an interactive touch screen option. The sleek design is an added advantage that results in more users getting attracted towards it. Like other storage and media devices, iPod too is prone to data loss due to various reasons similar to the ones that affect other storage media. However, data recovery experts need to keep in mind that to recover deleted files from iPod, the makers of data recovery software need to approach the iPod in a different manner.

Designers of data recovery software need to make sure that data present on the iPod can be accessed using the data recovery software. This turns out to be negative in case of the iPod Shuffle and the iPod Touch and hence there are very limited numbers of software that support recovery from these models. The other thing that makers of photo recovery software need to keep in mind is to check whether the recovery software supports both Mac and Windows OS, and hence design photo recovery software for Mac and Windows in such a manner so as to provide support for the rest of the iPod models.

Introduction: The familiar “qwerty” keyboard layout, originally designed for the mechanical typewriter, has been around since the later half of the 19th century. It survived the transition to the electronic computer keyboard and has become the standard way of entering text into a computer. However, when it comes to using it with a touchscreen, it has problems. This article discusses those problems and describes some research being done on a new method of text entry that is fast and tailored specifically to work with the touchscreen.

Problems with QWERTY: Recently touchscreen versions of the “qwerty” keyboard have appeared in smart-phones and tablets. These keyboards display a tiny version of the “qwerty” layout, named after the top left row of characters on a standard keyboard, and invite the user to tap one of the tiny keys to enter each character.

Any keyboard relying on pressing a separate key for each character, critically depends on the tactile feedback provided by the mechanical keys. When your eight typing fingers are placed above their “home” keys, you can feel the keys’ contours and thus can tell when your fingers stray from their home position. This frees your eyes for other things, like the text you might be copying or reading, or the person you are with. It also speeds text entry by eliminating the need for eye-hand coordination. Once the key positions have been memorized, i.e. once touch typing has been mastered, a “qwerty” keyboard can be quite fast.

This cannot be done with the touchscreen version of the “qwerty” keyboard because there is no tactile feedback. Because the screen is smooth, you can’t feel the keys. Even if you could, your fingers must be off the screen between key taps. To compensate, you must use your eyes to monitor the location of your fingers. This kind of eye-hand coordination is especially difficult with smartphones. Often the key images are tiny and are blocked from view by your fingers! Although the swiping keyboards, like Swype, can reduce the amount of finger movement, it still doesn’t eliminate the need for good eye-hand coordination.

As a consequence many tasks, normally done with a computer keyboard, are cumbersome with the touchscreen version. Copying text becomes particularly difficult in that your eyes must constantly jump between the text being copied and the keyboard. When in a meeting or classroom where notes are being taken, where a smartphone or tablet would really be handy, the same thing happens. The keyboard is also slow and error prone because of the eye-hand coordination needed to operate it.

There’s another Way: Although the touchscreen is clearly not well suited to emulating a typewriter or computer keyboard, there are many aspects of the touchscreen that lend itself to making a good text entry device. One of these is the ease of making swipes due to the screen’s smooth surface and the ability of the software to track the fingers’ positions. This has been demonstrated by the success of the pinch gestures pioneered on the iPhone.

To take advantage of this feature, what if each key press were replaced by a unique gesture? This would eliminate the need to constantly look at the input area since the gesture can begin anywhere.

More Fingers: One challenge with this approach, is devising enough, easy to make, unique gestures to allow for the 26 letters of the alphabet as well as some shifts and punctuation? One way is to use a small set of single finger gestures and combine them with multiple fingers to make possible a larger number of multi-finger gestures. Although more fingers could be used, three fingers were chosen here to be compatible with the smaller screens found on smart-phones. There are four unique combinations of three fingers:

• One finger by itself.
• Two adjacent fingers
• Two non-adjacent fingers
• All three fingers simultaneously

Now assume, when making a multi-finger gesture, all the fingers simultaneously do the same single finger gesture. One obvious single finger gesture is a simple tap where the finger comes up at the same place it goes down. Others are the four simple swipes: up, down, left, and right. Eight other gestures are curved swipes that start in one of the above four directions and end in another. This results in a total of 13 single finger gestures: one tap, four simple swipes and eight curved swipes. Combining these with the four finger combinations above, results in 52 unique three finger gestures. This is comparable to number of keys on a typical “qwerty” keyboard.

The frequency of use of letters and punctuation in English are then used to pair the most frequently used characters and shifts with the simplest to perform gestures to maximize speed. For example the fastest gestures, the four possible taps, are assigned to the “space”, “a”, “e”, and “t”, the most frequently used characters in English. To aid in learning the gestures, a table is shown under the fingers that tells you how to make the gestures.

Because the taps are very fast and the swipes only a few milimeters, text entry with this type of text entry can be fast. A three finger version has already been demonstrated at over 40 words per minute.

Summary: Although the standard “qwerty” keyboard, invented over 140 years ago, has been successfully used as a computer keyboard, it’s use with a touchscreen has serious limitations due to lack of tactile feedback. An attractive alternative to this is being developed in which each character is represented by a unique multi-finger gesture. This removes the need for eye-hand coordination and may finally make possible fast, eyes-free text entry on touch-screen devices like smartphones and tablets.

If you love the look of beautiful fireplace screens but do not have a fireplace in your home, why not consider using one as wall art? These beautiful fireplace accessories are available in many unique styles, many of which can be adapted easily to serve as wall decorations instead of fireplace protection. Here are some decorating tips you can use to transform a simple fireplace screen into a stunning piece of wall art.

Choosing a Fireplace Screen

There are so many different styles of such screens available that it might seem difficult to choose the perfect one for your wall. If your home features a rustic style of decorating, an iron fireplace screen could be quite complementary. Iron screens can also be used to add a traditionally authentic touch to a Tuscan decorating style. Brass and copper screens can also work beautifully as wall décor. Antique screens often work especially well, because they are usually crafted in a very ornate style.

However, they are also usually quite heavy, so be sure to provide them with adequate support when hung upon the wall. Even glass fireplace screens can work well when displayed as wall art. In fact, glass screens also adapt quite nicely when used in front of windows to add a decorative touch, especially if the screen includes stained glass features. Glass screens also look nice when displayed on the wall with a mirror mounted behind them.

Transforming a Fireplace Screen

When you first look at a fireplace screen, you might not immediately see it as wall art. But, once you remove the legs, you’ll begin to see that what you really have is a flat panel that in many ways resembles a trellis. Of course, you can always just hang the screen on the wall “as is,” after removing the legs. But, with a few embellishments, you can transform your simple fireplace screen into a truly beautiful piece of wall art.

Decorating Ideas with Fireplace Screens

Mounting a flat mirror on the wall behind the screen will add a very decorative look, whether you are using a glass or a metal screen. Or, mount a metal screen to a piece of wood to create a rustic-looking wall display. Frosted glass, stained glass or various kinds of papers can also be hung behind the screen, accentuating its decorative look. For example, a beautiful black cast iron fireplace screen would look great mounted on a piece of rustic wood, with cast iron hooks hung along each side to add functionality.

Or, add delicate rice paper to the back of an intricately designed copper or brass screen for a vintage look. In a Tuscan styled room, choose an iron screen with a trellis design that will blend nicely with the overall natural look. Hang a few wall planters beneath the screen, and allow ivy or other vine plants to use the metal screen as a trellis. In the kitchen, try framing the screen with terra cotta tiles, after mounting it on the wall. If desired, you could even paint a screen to add extra design pizzazz.

If there is any one phone which came and instantly became a sensation it is undoubtedly the iPhone from Apple Inc. A product of the world’s most trusted and innovative brand Apple, the iPhone really took the markets by stride and never looked back since its launch in 2007. Apple’s iPhone reached the zenith of success in the shortest time period in spite of belonging to the high price band has been a proof enough that if the product is right and innovative then mere price hurdles can’t be an obstacle in attaining instant success.

Apple’s most distinctive product quality has always been great user experience and simplicity in design and that’s what makes it so remarkably different. At a time when the market was congested with fast selling brands like Nokia, Sony, Motorola, etc. the iPhone came with the most innovative concept of touchscreen technology which was user friendly and easily accessible. Although, touchscreen has been in use for past many decades but its use was limited to specific technologies but, iPhone managed to provide the widest platform to this touchscreen technology by making the phone completely touchscreen enabled. The simple and innovative design devoid of too many buttons and distractions iPhone became an instant hit and star in the eyes of the users and the craze became so high that people started queuing stores before the launch of new versions and the same has been maintained for the nine generations of iPhone’s released till date. Simple slate design, interactive interface, own operating system, high speed, great camera, exclusive and the biggest IOS app store are some of the features which have always made iPhone’s stand apart from the crowd and maintain their exclusivity.

Apple will be launching its new iPhone 7 and its variant 7s this year and the hype around the phone and its technology has already started building. People as always are curious about the new techniques that will be used in this installment of iPhone and the particular features that will adorn it.

The iPhone’s have always managed to provide faster speeds even with low ram due to their integrated circuits and advanced technology and with iPhone 7 and 7s the trend is expected to continue. With high resolution 12 MP primary and 5 MP secondary camera this phone will be a delight for the selfi lovers. Siri, the intelligent personal assistant, one of the most innovative and distinguishing attractions of iPhones is expected to be more advanced with natural language command and dictation and hence interacting with the phone is going to be much simpler than ever.

Silicone rubber keypads are the most widely used form of switching technology today. They offer reliability, long life and design flexibility. There are some simple rules and basic design elements to consider when designing a silicone rubber keypad.

Key design will vary with the functional and aesthetic requirements of the application. It is possible to mold a key in almost any shape and to fit almost any configuration. It is important to remember that the key shape will affect the feel of the key. While a circular shaped standard key will have a consistent feel across the entire surface a half-moon shaped key will respond different depending upon where the key is pressed.

Once you have decided upon a key shape and layout; the next item to consider is the method for marking the rubber and creating legends. There are three common methods for marking keypads; printing, laser etching, and plastic key caps.

Printing

Printing is the most common method of marking rubber. The rubber is fixtured to flatten the key top then screen printed. There is no limit to the number of colors available. The arc of the key top determines how far printing must be set back from the edge of the key.

There are currently several options available for improving legend life with printed rubber.

• Plastic Key Caps – custom molded clear plastic is adhered over the legend or molded into the rubber
• Oil or Epoxy Coating – coating is deposited on the top surface of the key over printing, available in matte, semi-gloss, or gloss finish
• Drip Coating – drip coating can be hard or flexible. It adds a glossy layer over the key top. It can not be used on some keys with sharp angles. Hard coatings are subject to cracking if the key has large surface areas.
• Parylene Coating – offers the highest level of protection for a non-plastic coating. Parylene bonds to the rubber at the molecular level.

Laser Etching

Laser etching is especially well suited for applications where the keypad is backlit. Etching typically involves three production steps.

1) Translucent rubber (any color) is sprayed with a translucent base coat ink which will be the legend color that is visible to the user.

2) Rubber is sprayed with an opaque top coat ink which will be the overall color of the keypad.

3) The top coat of ink is laser etched away using high speed etchers to reveal the base coat.

Alternatively, you can decide to use a single translucent or opaque rubber ink and laser etch the legends revealing the color of the rubber that is used.

Plastic Key Caps

The longest lasting legend type is custom molded plastic. Plastic legends will not wear out. Many cell phone keypads are designed with plastic keys over rubber.

Functional Design Considerations

Snap Ratio & Tactile Feel

The snap ratio of a keypad determines the tactile feel experienced by the user. The recommended snap ratio for designers to maintain is 40%-60%; if dropped below 40% the keys will lose tactile feel but have an increased life. Loss of tactile feel means the user will not receive a ‘click’ feedback during actuation.

Snap ratio is calculated by taking the [actuation force (F1) – contact force (F2)] / actuation force (F1).

Most customers do not design the web and rely upon the manufacturer to design and meet the requirements.

Reducing Rocking Action

A common problem with rubber keypad design is the rocking action that can occur when a key is pushed. Rocking action can reduce the life of the keypad, make actuation difficult for the user, and cause other problems. The following suggestions will assist in reducing this problem.

• Add stabilizing posts on base of key
• Keep key stroke as near 0.8mm as possible
• Keep web length to a minimum
• Keep web angle close to 40°
• Actuation force of 80-150 grams for keys 10-15 mm high and 150-175 grams for keys 15-25mm high

Return force should also be set at 30-35 grams to ensure that keys do not stick.

Switch Life

The web design and the durometer of the rubber are the two factors that affect keypad longevity most. The design should reduce stress on the rubber if long life is desired. Using higher durometer silicone, increasing the actuation force, or increasing the stroke will all decrease the keypads life.

Rubber Hardness

Rubber hardness for a keypad can vary between 30 and 70 durometer (Shore A). Typically, most keypads are built between 40 and 60 durometer.

Minimum Key Height

For any design, calculate the minimum key height as follows; Keypad Base Thickness + Bezel Thickness + Stroke of Key + 0.5mm.

Contacts

The carbon pill is the most common contact because of its long life (>10 million actuations) and low resistance (Printed Circuit Board Design

The rubber contacts need to make contact with a circuit underneath. Rubber key mats themselves are very reliable in operation. However, when considering a PCB design, the environment in which the keypads are used must be considered to ensure that the complete switching unit is reliable. imum of 1.25 times.

Flexible Printed Circuit Design

Rubber keypads are typically used with printed circuit boards. However, many rubber keypads are also used with flexible printed circuits. Flexible circuits can be made of polyester or copper (Kapton).
