2013 Smartwatch Comparison Guide

Gizmag compares the biggest smartwatches of 2013

Is it worth buying a smartwatch this holiday season? Or are you better off waiting for Apple and Google to enter the race? Well, though the product category is still evolving, we've enjoyed our time with most of the early smartwatches we've reviewed. Let's line some of them up, compare their features and specs, and see if it's worth pulling the trigger.
  • Pebble
  • Samsung Galaxy Gear
  • Sony SmartWatch 2
  • Qualcomm Toq
  • Martian
Before we jump in, keep in mind that the Martian smartwatch comes in two other flavors, but for simplicity's sake, we're focusing on the Passport model. Besides some minor size and weight differences, the biggest difference is the watch's look.
Also note that we're leaving out wrist-based fitness trackers, like theJawbone Up, Nike Fuelband, and Fitbit Force. There's a little overlap there, but this guide is about the watches that have a broader focus.

Standalone smartwatch?

Just so you know what you're dealing with, none of these watches are standalone wireless d...
Just to be crystal clear about what we're dealing with here, none of these watches do diddly-squat on their own. You'll need to pair each of them with a compatible smartphone, or else there won't be anything "smart" about it. These are smartphone accessories, not smartphone replacements.

Android compatibility

Compatibility with Android phones
All of these watches are compatible with at least some Android phones. Four of the five will work with just about any semi-recent Android handset. Each phone has its own companion app that you can download, usually from the Play Store.
The most limited is Samsung's Galaxy Gear, which is only compatible with a few Samsung phones. It syncs up with the Galaxy Note 3, along with Galaxy S4s and S3s that have been updated to Android 4.3. Not every carrier has pushed that update yet, so be sure to double check your version before plunking down for the Gear.

iPhone compatibility

The Pebble and Martian are compatible with iPhones
Quite a different picture for iPhone pairing, as only the Pebble and Martian smartwatches play nicely with Apple's handset. They each have App Store apps that will send some of your iPhone's smarts to your wrist.

Android notifications

Each of these watches offers some kind of notifications when paired with an Android phone
Notifications are one of the biggest perks of having a smartwatch. Most of our watches will push all of your Android phone's notifications to your watch, vibrating your wrist. The only caveat here is that full Android notifications with Pebble and the Sony SW2 require third-party apps from the Play Store.

iPhone notifications

Only the Pebble gives you full notification support on the iPhone
Pebble was recently updated to push all of your iPhone's notifications to the watch. Martian's iOS notifications are limited to calls, text messages, calendar events, reminders, Facebook and Twitter, and (non-push) email. Martian tells us that a future update, though, will expand that to all of your phone's alerts.

Voice assistant

The Martian's Siri and Google Now voice control compatibility is its killer feature
This is the Martian watch's killer feature, as it supports Siri on iOS and Google Now on Android. The watch acts like a Bluetooth headset, letting you use your voice to do things like send messages and emails, set reminders, check the weather, make reservations, get sports scores, and much more.
Samsung has its own S Voice assistant baked into the Galaxy Gear, but it isn't on the same level. S Voice is basically a lackluster Siri knockoff, and the Galaxy Gear version is even more limited than the full version found on Samsung phones.
We think voice is the most logical and natural way of interacting with a smartwatch (and probably any wearable computer). In that respect, the Martian watch is, for the moment, in a league of its own.

Size

Listed dimensions for the watches' faces
These are the dimensions for each watch's face. The Galaxy Gear is the biggest, but they're all somewhat big and beefy. For that reason, we think this first batch of smartwatches work well on men's wrists, but not so well on women's (typically smaller) wrists.

Weight

The Sony SmartWatch 2 is the heaviest in this bunch
Weight isn't much of a concern here, as none of these feel too heavy on your wrist.

Build

Build materials for the watches' main faces
Qualcomm's Toq watch hasn't been released yet, and we aren't quite sure what build materials it uses. But we've had plenty of hands-on time with the other four, and all but the Pebble are metallic.

Colors

Color options available for each watch
The Pebble and Galaxy Gear are sold in a bunch of colors, and all but Sony's SmartWatch 2 come in at least two hues.

Alternate styles

The Martian is sold in two other variants, in addition to the Passport style pictured in t...
The Martian smartwatch is the only one in this crop that is sold in several different styles. As we mentioned, we've been focusing on the retro-looking Passport model, but Martian will also sell you its more modern-looking Victory and colorful G2G designs.

Screen size and resolution

Screen sizes and resolutions
Four of the five watches have screens dominating their faces. The Galaxy Gear's is both the biggest and sharpest.
The oddball here is the Martian, which has a small horizontal screen sitting below a traditional-looking analog watch. This makes it the most incognito-looking smartwatch in this bunch ... well, at least until you start talking to it.

Screen type

All of these screens should do well in direct sunlight
Three of the watches rely on touchscreens, while the Pebble and Martian stick with buttons on their sides for input. The Pebble and Martian are also the only watches in this bunch that lack color displays.
They all work pretty well in direct sunlight, and we didn't have any problems with any of them under extremely bright sun (not including the Toq, which we haven't tested yet).

Phone calls

The Galaxy Gear and Martian let you place and receive calls on the watch
If you dream of Dick Tracy-like phone calls on your watch, then the Galaxy Gear and Martian both deliver. We didn't have any problems with call quality on either watch.
The biggest difference is that the Gear's mic and speaker are on the strap, so you're better off holding it so the inside of your wrist is closer to your face. On the Martian, the mic and speaker live on the watch's main body.
The other three watches let you initiate and accept calls from the watch, but since they lack microphones, you'll need to use a Bluetooth headset (or your phone) for the actual call.

Camera

Only the Galaxy Gear has a camera (on its band)
It's debatable whether a smartwatch needs a camera, but if you fancy one, the Galaxy Gear might be the watch for you. There's no front-facing cam for video chat, though. The Gear's camera is on its strap, so it's meant more for snapping quick pics without pulling out your phone.

Fitness tracking

All but the Martian offer some kind of fitness tracking (usually via a third-party smartph...
Along with notifications and voice control, fitness tracking is one of our three favorite features to have on a smartwatch. None of these watches are dedicated fitness trackers, but four of the five offer some kind of pedometer functionality, either natively or through third-party apps like RunKeeper or Runtastic.

Battery life (estimated)

Estimated maximum battery life, according to manufacturers
These are the manufacturer estimates for each watch. In our testing, we'd say the Pebble is going to last the longest. On the other end, the Galaxy Gear will probably need to be charged every night.
Until we get our hands on the Toq, we're left with Qualcomm's vague "multiple days" estimate.

Bluetooth

The watches that support Bluetooth 4.0 Low Energy have the advantage, as your phone won't ...
Your watch needs to connect to your phone somehow, and that "somehow" is Bluetooth. Here the Pebble, Galaxy Gear, and Martian have the advantage with Bluetooth 4.0, including the Low Energy variant. If your phone supports BT LE (many high-end phones from the last year do) then the watch's drain on your phone's battery life will be minimal.

Wireless charging

The Toq will ship with a wireless charging dock included
Qualcomm's Toq charges wirelessly, and you get a wireless charging dock along with your watch. It's hard to imagine an easier way to charge your watch at night.

Water resistance

Water resistance for each watch
We aren't yet sure about the Toq, but all of the others offer some kind of water resistance. The Pebble offers the best water protection, as you can go swimming while wearing it (we swam many times while wearing our review unit without any problems).

NFC

The Sony SmartWatch 2 has an NFC chip, but it's only used for pairing the watch with an NF...
Near-field communication (NFC) could have some interesting applications for smartwatches down the road, like easy file sharing or even mobile payments. But for now, only the SW2 has an NFC chip, and it's only there to help with your initial setup.

Swappable band

Three of the five watches let you swap in any standard 22 mm watch band
If you aren't happy with your watch's default band, three of the five watches let you swap it for any standard 22 mm band.

Pricing

Prices for each of the watches
It looks like manufacturers are still feeling out what customers are willing to pay for a smartwatch. Pebble is the only one falling under US$200, while the Toq will cap out at a relatively pricey $350.
Both the Passport (pictured) and Victory models of the Martian cost $300, while the G2G edition comes in a little cheaper, at $250.

Wristward bound?

With our smartphone and tablet comparisons, the focus is exclusively on which product is best for you. With smartwatches, though, the first question to ask is whether you want a smartwatch at all at this point. They aren't for everyone. It's completely possible that the product category won't go mainstream until Apple or Google jump in (if it does even then).
But in testing four of these five watches in the last few months, we find it hard to go back to not wearing some kind of smartwatch. Notifications on your wrist let you leave your phone in your pocket or on the charger most of the time. The wrist is also the perfect place to quickly view fitness tracking info. And Siri and Google Now – exclusively the domain of the Martian right now – are tailor-made for hands-free computing.
As with all of these comparisons, the "winner" is going to depend on what you're looking for. The Galaxy Gear gives you the most features, but its phone compatibility is also by far the most limited in this group. Pebble lacks some of the Gear's more smartphone-like features, but it has a lot of software support and a great price. We're also pretty big fans of the Martian smartwatch, for its incognito look and Siri compatibility.
Whichever direction you choose – even if that means holding out for Apple's and Google's rumored takes on the smartwatch – hopefully you're a little clearer on what kind of bang the current crop gives you for your buck.

Modular Robotic

MOSS modular system keeps DIY robotics simple

One of the robotic creations possible with MOSS modular robot construction system

Colorado-based Modular Robotics has taken its Cubelets robotic building blocks to the next level with MOSS, a modular robot construction system that requires no coding or wiring skills on the part of the user. The kits are made up of various modules that communicate with each other via a single button contact and can be snapped together using magnets.
Like the Cubelets system, the individual modules of MOSS boast different capabilities that are signified with simple color-coding. The current color scheme – which may change – sees yellow faces conducting power, blue faces sending data, green faces receiving data, and purple faces allowing power and data to pass through uninterrupted. Some modules with multiple capabilities sport faces of different colors.
However, unlike Cubelets, which are all cube-shaped and feature magnets on each cube face that allows them to be connected together, MOSS modules feature neodymium rare earth magnets that allow them to be connected with each other using carbon steel ball bearings. This offers much more freedom in terms of robot design.
A carbon steel ball bearing/neodymium rare earth magnet connection system provides plenty ...
Cube-shaped modules still form the heart of the MOSS system, providing everything from power, a variety of sensors, and even Bluetooth connectivity, but the addition of various connection pieces, wheels, knobs, braces, etc, allows users to really let their creative juices flow.
The ball bearing/magnet connection system alone opens up a host of possibilities, with a single ball bearing connection creating a ball joint, two ball bearings creating a hinge, and three or four forming a rigid structure.
Through its Kickstarter crowdfunding campaign, Modular Robotics is offering various kits that start at US$59 for a Simple Starter Kit that can be used to build (among other things) a robot that will turn itself towards a light source, through $379 for an Advanced Builder Kit to construct a Bluetooth controlled car, up to $949 for a Mega Bundle that includes a number of bundles in one. There is also a Shogun Tank kit designed by Huck Gee that features a projectile-shooting turret that is controlled via Bluetooth.
The company has already passed its $100,000 goal with still more than 10 days remaining in the campaign. Deliveries are expected to begin in February, 2014.
The team's video pitch that demonstrates the MOSS system can be viewed below.

Nanoscale - How small is small?

How Small Is Small? 

The Nanoscale Explained in One Chart

At a certain point, very small is just very small—at least to the naked eye. 

But on the nanoscale, much smaller than the width of a human hair, scientists 

are setting itty-bitty world records and creating tiny works of art.

Nano art has come a long way since researchers arranged atoms to spell IBM in 1989. 
The latest feat is Mini Lisa, a detailed grayscale version of the Mona Lisa on a canvas just 
32 microns across—one-third the width of a hair. 
The image was created with a new technique in which the heated tip of a powerful microscope 
controls the speed of a chemical reaction at each pixel: More heat produces a faster reaction 
and the lighter shade of gray. Below and to the left we show where the Mini Lisa fits on the 
nanoscale. The visualization compares 11 items, showing just how small each one is in 
comparison with the object above. 



* 1913 -- Bohr Model of the atom developed
** 1953 -- DNA's double helix discovered
*** 1971 -- First microprocessor (Intel 4004)
**** 1981 -- Invention of the scanning tunneling microscope

From its creator: “In our loud and busy world a moment of silence has become a scarce and almost luxurious experience. The pebble like device you can see here lets you reclaim that silence for your home. With its concentric broadband antenna rings, it harvests the energy of electromagnetic noise from Wi-Fi, and similar signals and this way also reduces the level of e-smog pollution in your environment.”

Liquid Scanner

Watch A Machine Tell The Difference Between Soda And Liquid Explosives

By Kelsey D. Atherton


The problem with liquid explosives, besides being explosive, is that they often look just like non-explosive liquids. Since 2006, to protect against the threat of those explosives, people traveling by air in America have been limited to one quart-sized bag for liquids, each in a container no larger than 3.4 ounces. That size limit has, at best, a questionable impact on safety, but a new device being developed by Los Alamos National Laboratory could eventually make the scanning process less painful. Called the MagRay, it's designed to scan liquids and quietly differentiate between the safe and unsafe. And now Los Alamos has released a video showing off the tech. 
The MagRay essentially combines an X-ray and an MRI to differentiate between, say, a soda, and something more suspicious. Liquids are placed into the scanner, which, according to LANL researcher Larry Schultz, can give of a measure of how "sludgy" a liquid is, an indication of what might be inside the can or bottle. Another measure is X-ray density, or how difficult it is for X-rays to show through the liquid. With that data, the machine paints a fairly distinct portrait of the liquid, and a simple computer interface shows the most important information about the liquids in a giant colored circle: red for unsafe, green for safe, and more details presented alongside. The research is supported by the Department of Homeland Security, and it's easy to see how an airport security checkpoint in the future could employ a liquid-scanning device like the MagRay.
The device has been in development since at least 2007, but it still may be a few years before MagRays can scan Thanksgiving travelers' homemade gravy.

Self Healing Smartphone

LG's Truly Flexible Smartphone Actually Heals Itself After Knife Scratches
source: says.com

The LG G Flex may be one of the first smartphones to come with a curved display, but that’s not its only atypical feature. LG has been touting the device for its “self healing” capabilities since it unveiled the phone in October, but now one YouTuber has put LG’s tech to the test.


Futuristic Flexible Smartphone

Concept Flexible iPhone-bracelet


Future technology Concept Flexible iPhone-bracelet

Apple is trying to do everything possible to maintain the status of an innovative brand. This is very much possible , but truly revolutionary technology in the range of U.S. brand appear infrequently,perhaps,marketers do not foresee high demand on the futuristic solutions . Disadvantages of the real world , as always, are replenished worthy concepts. 
The authors of the new work is a designers Degra Studio (Poland). In the external form the flexible transparent mobilephone can guess the iPhone with its unique interface. However, the creators of the concept chosen not to contact Apple and has given the name of a work X Phone. The smartphone boasts a crystal-clear flexible display, that folds out to form a closed shape. 

To implement the project X Phone required display with the organic light-emitting diodes (OLED). Prototypes of these components exhibit regularly at major exhibitions such companies as Sony, LG and Samsung. However, on a market still come out only curved, but not flexible displays. It is a pity,because these toys certainly would enjoy demand. With reasonable price,of course.
