Thousands of VSAT Operators Left in Lurch by Indian Satellite Failure


http://spacenews.com/40021thousands-of-vsat-operators-left-in-lurch-by-indian-satellite-failure/
by  — 
PARIS — India’s Insat 3E telecommunications satellite failed in orbit the week of March 26, forcing thousands of operators of VSAT satellite antennas to shut down their operations and await instructions on where to repoint their hardware, industry officials said March 28.
Insat 3E, operating at 55 degrees east, covers the entire Indian subcontinent and the Indian Ocean region. It was launched in September 2003 and carries 24 C-band and 12 extended-C-band transponders.
The Indian Space Research Organisation, which builds India’s fleet of telecommunications satellites and also acts as a satellite regulator — much to the dismay of non-Indian satellite operators seeking broader entry into the Indian market — did not immediately respond to requests for comment on the nature of the failure or possible remedial action.

Chromecast

http://techcrunch.com/video/chromecast/518711984/

Google’s Chromecast turns the phone in your pocket into a really, really great TV remote — which is great, until your TV remote is nearby, but your phone for some reason isn’t.
Surprise! Chromecast suddenly lets you pause and un-pause videos with your TV’s infrared remote.
While it doesn’t seem that Google has officially announced the functionality, I’ve just tested it myself — and sure enough, it works. Here’s an on-the-fly demo:
“But wait!” you say. “The Chromecast doesn’t have an infrared receiver! How can an infrared remote control it?”
It’s all working through the magic of HDMI-CEC, the same protocol that allows the Chromecast to automatically turn your Smart TV on when it’s video time.
The bad news: that means it won’t work with all TVs, though most made within the last few years should be HDMI-CEC enabled. Some TVs sort of hide the protocol to avoid confusing people — so if you’re not sure, check your manual. (Oh, and your TV’s remote will need a dedicated play/pause button, of course.)
The functionality also seems to be enabled on an app-by-app basis. It doesn’t work when you’re casting from Hulu, for example — but from YouTube? It worked immediately, without me having to change a thing.

Why Facebook Messenger Is A Platform—And WhatsApp Isn’t

http://readwrite.com/2015/03/27/facebook-whatsapp-messenger-texting-platform

Because Facebook wants to own all the chats, everywhere.

WhatsApp doesn’t want to be a platform. Co-founder Brian Acton, on a panel Wednesday at Facebook’s F8 developer conference, made that very clear. Unlike its sibling service Messenger, which has started courting outside developers and businesses, all that matters to WhatsApp is that the service remain stable, simple and unfettered for its worldwide audience of 100 million monthly active users.

That matters to parent company Facebook too, but likely for different reasons.

WhatsApp—which sold to the social network last year for $19 billion dollars—offers an interesting counterpoint to Facebook's big Messenger push. Because with less redundancy between the two, the company could essentially own a decent chunk of the world’s conversations. 

The Network Effect

Imagine what it’s like using some of the most robust, dynamic mobile applications available today—complete with the sort of images, animated GIFs, music and videos that will assault Facebook’s Messenger app soon enough. Now imagine running that on a slow cellular Edge network straight out of 1995.

That’s precisely the patience-stretching scenario Acton imagines all the time, and it serves as a guiding principle for his work with the service.

In that regard, WhatsApp’s moves seem obvious. It became popular because it was built on some key fundamentals—namely no-fuss messaging that’s reliable, works in different languages and on as many gadgets as possible. Adding the complexity of outside integrations to the mix would only complicate things for a widespread service that has to work over a variety of networks all over the world—some of which can only muster rudimentary connectivity.

“The world is a very diverse place,” Acton told panel moderator and analyst Mary Meeker, "and networks can have any number of configurations and problems that impede or get in the way with messaging.” One of those problems, for a globally available texting service, is dealing with systems and networks in emerging markets—a key area for tech companies, including Facebook.

With Acton’s motto being “simplicity, simplicity, simplicity,” he can leave the complexities of media messaging to sibling services Instagram and Messenger.

The Big Picture

On Wednesday, an audience member asked when WhatsApp would release APIs (application programming interfaces) to let developers tie their apps to the texting service. Acton had bad news for him: "The answer I have is ‘not today’,” he said, later elaborating that APIs are not even on the road map for the foreseeable future.

But that’s not to say WhatsApp will stagnate. "This year, we’re focusing on voice, [and] we’re focusing on the Web product,” he said. "David [Marcus] is really championing the APIs.”

If WhatsApp leaves Messenger to handle Facebook's platform ambitions, that likely suits the parent company just fine. 

Messenger—Facebook’s other, homegrown messaging service—just unveiled a plethora of developer tools covering embedded videos, embedded posts, app linking and more. Marcus wants to give partners and other app makers the "opportunity to build on these platforms,” he said. And not just once, but often. 

“You want to build an app that will be there to stay," he said, "and you want to build creative tools that people will want to use repeatedly.” 

Some of those people will actually be businesses. Messenger looks intent on pushing its new vision of customer service that replaces logging into websites, punching through automated phone menus or waiting on hold, with chat threads. People could buy products, see their transaction info or receipts, shipping details, individualized promotions and other customer relations messages, all in a Messenger window. 

For now, Messenger doesn’t support cross-border transactions, so it's currently confined to the U.S. But consider it a first step in Facebook's larger ambitions. 

The two messaging services look like perfect foils for each other. While WhatsApp handles the fundamentals—making sure that anyone anywhere, regardless of phone or network, can use its service—Messenger can take on the more complex messaging tasks to satisfy users and companies on advanced networks. Between that and all the sharing that Facebook itself naturally manages, the company could have its fingerprints on an awful lot of conversations all over the world. 

"Build better" may be one of Facebook's F8 slogans, but it's the other one that suddenly has some extra context now: "This is only the beginning." When it comes to messaging, it certainly seems like it.

Immersis - Make Room for a New Game

https://www.kickstarter.com/projects/catopsys/immersis


The ultimate virtual reality experience for immersive gaming and video, sharable with others and adaptable to your living space.

The Content 

This is only the beginning. Immersis’ future content possibilities are unlimited!
Video Games : Any video game developed with a real-time 3D engine. The first specific plugin has already been developed for Unity 3D, the most important game engine on the market. A beta version plugin for Unreal Engine and a universal plugin (allowing any video game or 3D application to use Immersis) are also available. It will only take a few minutes for game developers to make their content compatible with Immersis, which will open all kinds of new opportunities for enriched game play. 


Videos : Until today, you could only visualise content created for 360° cameras alone, inside a VR headset. With Immersis, you will be able to experience as a group all of your sport accomplishments, your vacation memories, as never before. Some 360° cameras even permit for you to watch your panaromic videos in real-time. 
Photos : All panoramic photo formats are compatible and Immersis is compatible with theGoogle Photosphere format
Our Kickstarter backers are more than just buyers or product testers. You will be the explorers of the next immersive technology and you will help change the immersive experience from what we know today. You will be a part of a community that we create together, proposing and testing new ways to use Immersis, suggesting new evolutions in the technology and developing complementary products whether through the online community or at special events reserved for you.

How it works 

The main scientific obstacle that had to be addressed concerns calibrating the system todisplay the right information at the right place in the projection space and thus recreate the proper perspective from the user’s point of view. 
The method we have developed is three-dimensional, that is to say, it allows us to know the 3D position of each projected pixel (patent submited US-B-8 272 752). It is only because of this technology that it is possible to change the user’s point of view. Catopsys is the only company possessing this technology in any environment and several International patents have been filed.

A View-Master for virtual reality: Hands-on with Mattel's new AR, VR phone toy

http://www.cnet.com/products/new-view-master/

Mattel is relaunching View-Master, but as a virtual reality and augmented-reality phone toy. And I got to play around with it for a bit...or at least, some of the tech behind it.
Announced at an event in New York City, the new View-Master is a collaboration between Mattel and Google, whose virtual reality Cardboard app has enabled cheap do-it-yourself accessories to turn any Android phone into a mini-VR viewer. Mattel's plastic toy, which will debut in October, is like a more durable, plastic version of Google Cardboard, designed entirely for kids...or, maybe, also for grown-up kids like me. And the most brilliant part is it'll only cost $30.
viewmaster2.jpg
New View-Master, reborn as a phone accessory toy.Scott Stein/CNET
I used View-Master back when I was a little -- who didn't? It's a classic 3D stereoscopic picture viewer. Many people had even said Google Cardboard looked a bit like a View-Master. So is isn't a huge surprise that Mattel has suddenly announced a new View-Master with Google Cardboard VR capabilities added. I've always felt that virtual reality reminded me of early stereoscopic toys. And Mattel has keyed onto the same idea.
viewmaster1.jpg
The View-Master will fit most phones, according to Mattel: iPhone and Android alike.Scott Stein/CNET
The toy was only viewable in a mock-up prototype form at Mattel's event, but the design's pretty cool: it looks half old-school View-Master, half Oculus Rift. The inner plastic housing extends to hold many types of phones: Mattel says it's designed to fit the largest existing phones, and will even work with theiPhone 6 Plus and Nexus 6. A capacitive-touch side lever is used to "click" through scenes or into virtual environments, like the magnetized side switch on Google's Cardboard viewers.
Mattel's headset is designed with Google and Android in mind, but at launch is intended to work on "nearly all platforms," which includes iOS. That would mean a dedicated Mattel app which interfaces with the View-Master, but Google's Cardboard and Cardboard-ready apps -- many of which already exist on iOS, like VRSE -- will work too.
Mattel is planning to use View-Master not just for VR, but also for AR; little plastic reels that look like the old cardboard ones are really just flat coasters this time around, now with images on top which the View-Master reads and turns into pop-up augmented-reality models on your table, desktop or wherever else you place it. Multiple View-Masters could use one reel to access content if put down on a table, unlike the old pop-in reels. This type of augmented-reality tech has already existed for years in many apps and on some children's toys like the Nintendo 3DS (with its AR cards) and PlayStation Vita, but mixing it into a VR headset is a novel idea.
viewmaster3.jpg
Scott Stein/CNET
I didn't get to use the actual Mattel prototype, but we tried View-Master's augmented-reality tech on phones and Google Cardboard viewers. There were three reels to try: a dinosaur one made a little dinosaur pop up on the disc on the table in front of me. When I aimed a dot and clicked on it, I was suddenly surrounded by a prehistoric 360-degree panorama with 3D dinosaurs. Clicking on them brought up facts, too.
Looking at the space disc with Cardboard on brought up a pop-up moon and Earth; clicking on it took me to a panorama of the moon, with pop-up clickable photos of NASA missions. A third, San Francisco-themed, had little mini-models of Alcatraz and the Golden Gate Bridge that turned into VR photo panoramas. To exit any of the virtual panoramas, you look down and click on the side...or, remove the View-Master from your face. The View-Master comes with one reel in its $30 package, and extra reels will cost around $15 each. No, older View-Master reels don't work in here, but it sounds like Mattel is exploring re-releasing content from some of the back catalog 10,000 older ViewMaster reels.
viewmaster4.jpg
The "reels" don't actually go in the View-Master, they simply sit on your table.Scott Stein/CNET
There's no strap to keep the View-Master on: this is a hold-to-your-face toy, much like older View-Masters and Google Cardboard. Mattel has promised that the tech has already been vetted by pediatric ophthalmologists, and is meant for children ages 7 and up -- in short, bite-sized sessions.
The View-Master may work with other toys, too, like other app-ified toys in the past, but for now it's really a fancier plastic Google Cardboard viewer, with additional Mattel support. That's not a bad thing at all: at $30, this is a pretty awesome little stocking-stuffer idea, and a fun phone toy. Just keep in mind that if you give this to your kid, it won't work without a phone popped into it.
By the time fall rolls around, Mattel may have other toys ready to work with it. Or, there might be many other companies ready to make cheap phone-enabled VR headsets, too.

BuzzFeed Expands Mobile Team By Acquiring “Visual Conversation” Startup GoPop

http://techcrunch.com/2015/02/19/buzzfeed-acquires-gopop/#7K29tS:gaL

BuzzFeed just announced that it’s acquiring San Francisco startup GoPop.
The startup was originally known as Zeega, and it was part of the first class at Matter, the Knight Foundation- and KQED-backed incubator for media startups. GoPop’s current offering is an iOS app for “visual conversation,” combining photos into simple animations (that’s a sample animation of the GoPop team above).
You can probably see some kinship there already, given BuzzFeed’s well-known fondness for GIFs. It sounds like the acquisition’s aim was to bring on some key team members to help with BuzzFeed’s mobile app development.
BuzzFeed says GoPop CEO Jesse Shapins will be leading product for the core app team, while his co-founder and CTO James Burns will lead a new experimental app group. Mobile designers and developers Joseph Bergen and Filipe Brandão are also joining. (And yes, they’ll be moving to BuzzFeed’s New York office.)
“We believe BuzzFeed is rapidly becoming the most impactful global media company, and the opportunity to lead new initiatives as the company expands its mobile footprint was irresistible,” Shapins said in the acquisition release.
A BuzzFeed spokesperson told me that the GoPop app will be taken down, but the company will host “a public archive of all Pops ever created, where each user will have a web profile with everything they’ve ever made.”
This is also the first acquisition to come out of Matter (which announced six new media partners yesterday). Matter managing partner Corey Ford told me via email that it was “incredibly rewarding” to see a team that “started Matter without exposure to mobile-first, user-centered, prototype-driven design process” become so strong that it was acquired by “the most innovative news company on the planet right now.”
The financial terms of the deal were not disclosed. GoPop had also raised funding from The Knight Foundation and Chris Sacca’s Lowercase Capital.

Smartwatch App Helps Track Glucose

http://www.wsj.com/articles/smartwatch-app-helps-track-glucose-1423443067?mod=e2fb

Medical-device maker DexCom Inc. is designing an app that will display readings from its diabetes glucose monitor on Apple Inc. ’s smartwatch, giving the watch an early foothold in the health-care market at a time when regulatory treatment of such systems has eased.
DexCom’s glucose monitor tracks a person’s blood-sugar levels continuously. The company has shown a picture of the app, which converts that data into a simple graph that is just a glance at the wrist away. It says the app is expected to be ready when the Apple Watch is launched in April.
Apple declined to comment. The company hasn’t accepted any apps for the coming watch yet but has provided guidelines and code to developers for creating apps for it. The latest iPhone operating system increased its health and fitness offerings.
The Food and Drug Administration had been closely scrutinizing such applications. But the agency loosened its oversight in late January, months after a group of software engineers, many of whose children have Type 1 diabetes, developed a system for monitoring diabetes patients’ blood sugar over the Internet. The system was distributed without first getting regulatory approval.
The group’s effort challenged the slow pace of innovation and regulatory approval in the field. It also highlighted the growing role that Silicon Valley companies and software developers hope to have in monitoring and maintaining people’s health.
Some 29 million Americans have diabetes. Between 5% and 10% of them have Type 1, an autoimmune condition in which the body is unable to convert glucose into energy. People with Type 1 diabetes rely on taking insulin and regular monitoring to make sure their blood sugar doesn’t go dangerously high or low, both of which can cause life-threatening conditions.
The DexCom monitor uses a hair’s-width sensor under the skin to measure blood glucose levels every five minutes.
Previously, the FDA considered glucose monitors and any associated software to be Class III medical devices, meaning they received the highest level of regulatory scrutiny. But the spread of NightScout, the system developed by the group of software engineers, and DexCom’s submission of a separate iPhone app for review prompted the FDA to change course last month.
DexCom’s monitors will remain Class III devices, but software that helps display the data they produce on mobile devices or smartwatches now only needs to be registered with the FDA and doesn’t require prior marketing approval.
The FDA has been reassessing its health-apps policies. “We felt that the risks that the app imposed weren’t as high,” said Alberto Gutierrez, director of the FDA’s Office of In Vitro Diagnostics and Radiological Health.
The issue came to a head last year when the group of software engineers, working on their own time, developed NightScout, which met a critical need. The software takes data from a glucose monitor made by DexCom, mainly for Type 1 diabetes patients, and uploads it to the Internet. That allows parents—and caregivers—to keep track of their children’ blood sugar from afar via their cellphones, tablets and Pebble watches.
NightScout spread quickly to thousands of users who found each other on Facebook andTwitter . By bypassing the FDA, the system’s creators skipped a process that had snarled or deterred formal development of similar products by medical-device companies.
Last fall, the group did take the invention to the FDA. The agency’s new rules give NightScout a pathway to regulatory compliance, according to FDA officials.
DexCom still needs to make sure its Apple Watch app complies with FDA rules. But thanks to the rule change, it doesn’t need to get approval before bringing the app to market.
Steve Pacelli, DexCom’s head of strategy, said the regulatory nod for the iPhone app came in January, much faster than the company expected.

The App Developer Checklist: 6 Ways To Keep Your Users Happy


http://readwrite.com/2015/02/02/app-developer-checklist-features-performance

1. Win the Performance Race

In the world of mobile apps, speed sells. On-the-go users don’t want to wait for apps to load or updates to install, and they don’t care if an app’s sudden popularity creates a bandwidth bottleneck. They just want it to load quickly and work smoothly.
In worst-case scenarios, users simply delete poorly performing apps. In fact, according to a survey by Compuware, 59% say they would drag an app to the trash if it’s too slow. Others find ways around the app—for instance, some savvy Facebook and Twitter users find that the websites often outperformthose apps on speed and performance.

2. End Wild Goose Chases

When it comes to app design, less is more. Often times, apps that have beenpraised for their design are laid out logically and simply, and they perform how users expect them to. When users click on a menu, they have a reasonable idea of where they will end up, without having to guess where to find what they’re looking for. 
It’s critically important that developers get the design right. According to an EPiServer poll, as many as 47% of users will delete an app if it's too difficult to use. That’s exactly what many iPhone users did back in 2012, when the iOS 6 software came equipped with a “disaster” called Apple Maps. The app was so difficult to use and inaccurate that it even spawned the Tumblr page, “The Amazing iOS 6 Maps,” which collected screenshots of Apple Maps glitches. Many iPhone users turned to Google Maps and then stayed there.

3. Keep The Same Experience, No Matter The Device

Some users spring for in-app purchases in a tablet app—like a new game character or extra features—only to find that the upgrade doesn't carry over to the same app on their phones. Or they start listening to a podcast on an iPhone, only to waste time on the iPad version to find where they left off. 
A user should be able to easily jump back and forth between different versions of the same apps on different devices, without feeling like they are starting from scratch. Unfortunately, these types of performance problems are only going to become more prevalent and frustrating for users as more people switch between multiple devices. In fact, Cisco estimates that there will be 1.4 mobile devices per person by 2018. 
Switching devices should be easy—like changing lanes on a highway. You may be in a different lane, but you’re still on the same journey. App users crave that same type of experience, and it’s up to app developers to ensure that theuser journey stays consistent across devices. 

4. Banish Count Appula

According to AVG's CTO Yuval Ben-Itzhak, "Apps are what make a phone, but they’re also what break it." There's some truth to that. Apps create millions of different experiences for users, but that potential can be wasted if they're "vampire apps."
Vampire apps eat up battery life, rack up data charges and dramatically impact overall device and app performance. Users can take steps to mitigate those effects. They can reduce data usage and battery drain by turning off location services or by using Wi-Fi instead of mobile network services whenever possible. New apps like Normal, which crowdsources information about how apps deplete battery life, also help. But ultimately, it shouldn't be up to the consumer to make up for these failings. 
App developers need to find ways to minimize data usage and streamline processing to improve performance and battery life. 

5. Remember Murphy’s Law

If an app's function doesn’t perform as expected, users will be sure to zoom in on it. Some will complain about it to friends. Others will give the app a one-star review or even delete it altogether. 
Let’s say you have a car rental app. It displays all available vehicles' make, model and year in a beautiful map of your surroundings. That’s all very helpful—but what if, because of unreliable network connectivity, the app can't actually book it? Or a glitch stopped the confirmation email from coming through, leaving you unsure if the request was received. Sounds like a fairly minor failure, but it leaves users with no confidence in the app.  

6. Play Nicely with Other Apps

The apps with the richest performing experiences don't stubbornly trap users in one environment. Instead, they interact with each other, so users won't have to duplicate their actions or zigzag between stock apps—even if they do roughly the same thing.
For instance, Instagram users are probably happy that they can have all of their pictures automatically saved to the “Photos” application on their iPhone. They can apply Instagram filters before posting it on the network, or share the original, unedited versions with friends who don’t use Instagram. 
Strong app performance isn’t just about how an app functions in a vacuum—app developers have to think about how their app fits into the larger ecosystem, as this is how users will derive true value.

App-ortunity Knocks

If you could send a new iPhone 6 owner back in time to 1998 to play Snake, he or she wouldn’t describe the game as fast, easy to use, responsive, interactive or compatible with other apps. But as technology has evolved, so, too, have user expectations.
For developers to live up to them, they need to understand that optimal app performance hinges on how well data is managed on the back end. If app makers need to think about how they can apply intelligent data distribution to make apps more lightweight, they can ensure that the data traveling across the network isn’t redundant or out-of-date. 
The backend is invisible to users, so they may not know whether apps are designed using intelligent data distribution. But they will notice when apps don't perform as expected.  

How Open Source Succeeds In The Cloud—It Trades Freedom For Simplicity

http://readwrite.com/2015/02/04/open-source-big-data-simplicity-not-freedom

Those new to open source won’t remember just how much of the early code amounted to little more than crappy-but-free clones of popular proprietary products. Boy, how times have changed.

Open source, once a clumsy (but free!) imitator of proprietary innovation is now doing taking the lead on industry innovation, with Big Data being the most obvious example. While this is a hugely positive industry shift, it also introduces complexities. Namely, with so much exceptional open source software contending to power your next Big Data project, how do you choose which to use?

Opening Up Innovation

Black Duck Software recently named its annual “Open Source Rookies of the Year,” pulling data from thousands of projects relative to project activity, commits pace, project team attributes, and other factors. Spanning cloud and virtualization, mobile, social media and more, they reflect the ever-increasing scope of code that is successfully developed in the open, rather than behind closed doors.

Nowhere is this trend more evident than in Big Data.

As Cloudera co-founder Mike Olson declares, “No dominant platform-level software infrastructure has emerged in the last ten years in closed-source, proprietary form.” That’s a stunning assessment, but it’s absolutely true. Open source may have come to life as an imitator, but it’s innovating at a frenetic pace in Big Data land.

Which may be a problem.

Spoiled By Open Source Riches

Big Data projects are now being released at such a frenetic pace that developers struggle to keep up. In case you’re just getting your feet wet with Hadoop, for example, you now need to consider Spark, Samza or a variety of other oddly-named but increasingly important Big Data tools.

Importantly, these tools are largely being born within enterprises like LinkedIn that have serious Big Data needs that no commercial software can solve. Even the National Weather Service has jumped in, open sourcing the code that powers its global forecast system.
While most companies won’t need such niche code, they may want the sorts of things released by the big Web companies. Take for instance, LinkedIn’s release of Apache Samza:

This leads to fantastic performance. It also leads to the question: what should a developer use to tackle her organization’s data load?

On the database side, there are hundreds of options, ranging from NoSQL databases like MongoDB and Cassandra to relational mainstays like Oracle and MySQL. Should a developer choose the most popular database, picking from a list like DB-Engines’ ranking? That’s one approach, but you could easilyend up with a big mismatch between the workload and the tool managing it.

If this seems like a trivial problem, it’s not. At all. I spent years working for Big Data infrastructure providers, and now work for a company trying to make sense of the deluge of open source Big Data tools. It’s hard to keep up, and very difficult to know which to use.

Closing Off Choices

One reason that Amazon Web Services (AWS) has become the go-to public cloud is that the company has managed to simultaneously offer a broad array of open source solutions to run (supported and unsupported) on its cloud, and a suite of proprietary services for everything from email to data warehousing.

Developers, anxious to “get stuff done,” can turn to AWS and know that they’ll have both a variety of options and the safety of a paved path.

Microsoft Azure has followed suit. Not content to roll out a Hadoop-based analytics service, for example, Microsoft is now close to releasing Cosmos, its parallel processing and storage service. Or take the company’s support for MongoDB, an open source document database, to appeal to those that want the popular NoSQL database. At the same time, Microsoft has rolled out its own document database as a service, for those that want a document database but may prefer Microsoft’s packaging of it.

Microsoft, in short, wants to provide choice to its customers, but curated and nicely packaged.

This looks like the future of open source infrastructure: free to download, but perhaps more useful rolled into a cloud service that removes complexity (and choice). It may not be what the open source crowd would prefer, but it may end up being the ideal way to turn open source Big Data innovation into solutions mainstream enterprises can actually use.

5 ways wearables must change to make us healthier in 2015

http://venturebeat.com/2015/01/01/5-ways-wearables-must-change-to-make-us-healthier-in-2015/



Many of us bought fitness wearables in 2014. We counted our steps, our distance walked, our quality sleep time. But almost as many of us probably ended up abandoning our new devices before we’d worn them even a month.
Fitness-tracking devices, like this one from S2H, can help motivate employees toward better health.
Because my job involves testing many of these devices, I’ve been through the adopt-and-abandon cycle several times over. I had hoped that one of these devices would stick — that I would continue wearing it and benefit from the so-called “actionable insights” gained from the data. But they all ended up in the junk drawer.
Here are some of the reasons that happens, and what needs to change to keep the wearable revolution headed in the right direction.

They need better functionality

Many fitness wearables on the market now are just accelerometers wrapped in a piece of plastic. The very limited set of features and functions that this enables is perfectly built for people who are OK with using a wearable for a couple of weeks then giving up. Many of these devices are so inexpensive that this loser of a use case can be a money maker for the manufacturer. But as the wearables market becomes saturated in 2015 this will be a tougher sell.
Many users will already have purchased (and thrown away) their first wearable, and will expect far more from their second one. In the last couple of months, we’ve seen wearables companies like FitBit and Jawbone begin to release devices that have more sensors and more refined algorithms for making sense of biometrics data.
The inclusion of a heartbeat monitor will become table stakes for wearables in the next year. They will not all be accurate, but consumers will begin to expect them. Manufacturers are also beginning to build smartwatch-like features (like notifications from a paired smartphone) into fitness wearables.

They need to be comfortable

This may sound fussy, but it’s a big deal. You’re asking me to wear your amazing device around day in and day out, even while I’m at the gym or in bed. So the thing has to be light, and it has to be comfortable. Many wearables simply are not comfortable on the wrist.
For instance, I was initially impressed with the Microsoft Band, but I eventually stopped wearing it because it felt to hard and blocky around my wrist. Plus, the touchscreen on the Band becomes very unresponsive when covered with perspiration.
Smartwatch makers need to take a deeper look into the materials available for watch bands, and get more creative about selecting them.

They should look good

Many wearables that entered the market this year were focused on hitting a low price point. For instanceXiaomi’s Mi Band sells at $13. Aesthetic appeal hasn’t been a priority, and cheaper wearables often look plasticky and toy-like.
Meanwhile, top-end fitness watches and smartwatches are often big and blocky. Part of that is an aesthetic problem, but part of it is a technical one. As more and more features and functions are built in to these devices, larger component parts, such as bigger batteries, are needed to run them. That’s why they’re bigger.
The lithium ion battery won’t be able to deliver the capacity improvements needed to get us through the smartwatch revolution. Manufacturers need to double down on power supply R&D and come up with some viable alternatives. This problem alone could kill the smartwatch category.

The numbers need to add up to something

At any one time I’m using several health devices, like a connected scale, a nutrition tracker, a sleep tracker, and a fitness band. I can open all the apps that accompany these devices and peruse all the numbers they’ve collected about my steps, deep sleep minutes, my calendars, etc. But what do I do with this data?
Too often wearables generate a lot of data, but they don’t give me contextual information I need to put the data to use. A device might give me my resting heart rate, but chances are it doesn’t know enough about me to tell me when my heart range has entered the danger zone. A dangerous rate for me, after all, might be perfectly fine for an athlete in training, or a life-threatening rate for someone who is morbidly obese.
I hope that smartwatch makers in 2015 will think of better ways to wrap enough contextual information around the numbers to make it all meaningful.

The apps should be easier to use

Some of the apps that accompany wearable devices are so poorly designed that it’s difficult to even see and make sense of the data they’ve collected. If the app is hard to read and understand, the device is basically useless. Since biometrics data is often best presented in charts and graphs, the app must make careful use of screen space to display it properly. Often, this doesn’t happen.
The numbers show that the market for health and fitness wearables is set to expand rapidly in 2015. As one wearable brand CEO told me, the devices are so easy and inexpensive to make, and the market is so ripe, he’d be crazy not to sell health wearables.
Hopefully, pure competition will weed the weak players out of the market, and new, more feature-rich and comfortable wearables will emerge.
