Use Your Arm as a Smart-Watch Touch Pad

Rather than playing games like Angry Birds by swiping your finger across a touch screen, you may someday be able to do so by swiping your finger across your arm.

Researchers at Carnegie Mellon University are making this possible through a project called SkinTrack. You’d wear a ring on your index finger that emits an electrical signal that can be picked up by an electrode-laden smart watch on your other arm. A paper on it will be presented next week at the Association for Computing Machinery’s computer-human interaction conference in San Jose, California.


SkinTrack, a research project from Carnegie Mellon University, lets you use your arm as a touch pad for a smart watch.

Wearable gadgets like smart watches can be hard to interact with because they tend to have tiny displays. So the researchers figured that using your skin—specifically your wrist and hand—as a touch pad could make it easier to do things like navigate maps, make calls, or play games.
Gierad Laput, a graduate student at Carnegie Mellon University and one of the researchers behind the project, says SkinTrack works similarly to how cell towers triangulate signals to figure out your phone’s location. The researchers got SkinTrack to determine when the finger was on the skin 99 percent of the time. And by arranging the electrodes in the smart watch in a certain way, they could determine in real time where the finger was, tracking its movements on the arm and hand.

SkinTrack can sense where your finger is on your skin and track it in real time.SkinTrack can sense where your finger is on your skin and track it in real time.

With SkinTrack, your arm could be used as a touch pad for all kinds of gestures, like dialing a virtual keypad.

To try out SkinTrack, the researchers made several demos, including one of an Angry Birds game that could be played on their smart watch. You swipe your finger up your arm to pull the bird back in a slingshot on the watch’s display. “And when you release, the app can know the finger is off the skin, so that’s like releasing the slingshot,” he says.

As a video of the project shows, it can also be used for all kinds of gestures—like swiping left, right, up, or down. It could also be used for making the skin a virtual number pad or other kind of button pad, Laput says, or opening an app by tapping a specific spot or gesturing a letter on your arm (writing an “M” with your finger might prompt music to start playing, for instance).

SkinTrack needs work if it’s going to make it onto your body at some point, though: the ring would likely have to be much sleeker, and boast decent battery life. Laput thinks it would take a few years to make it accurate enough for anyone to use.

How to solve Gmail “Password incorrect” errors

There are several reasons why you might see see a “Password incorrect” error when signing in to Google using third-party apps like iPhone’s Mail app. In some cases even if you type your password correctly.

Here are the most common reasons you may see this error, and steps to take to access your account:

You’re signing in from a new location or device
To protect your account, Google might make it harder to sign in to your account if we suspect it isn’t you. For example, Google might ask for additional information besides your username and password if you are traveling or if you try to sign in to your account from a new device.

  1. Go to https://g.co/allowaccess from a different device you have previously used to access your Google account and follow the instructions.
  2. Try signing in again from the blocked app.

Your device or app may not support Google’s security standards
Some examples of apps that do not support the latest security standards include:

  • The Mail app on your iPhone or iPad with iOS 6 or below
  • The Mail app on your Windows phone preceding the 8.1 release
  • Some Mail apps (not built by Google) that come with your Android Phone
  • Some Desktop mail clients like Microsoft Outlook and Mozilla Thunderbird

To help keep your account secure, we may block these less secure apps from accessing your account. If this is the case, you have two choices:

  • Upgrade to a more secure app that uses most up to date security measures. All Google products, like Gmail, use the latest security measures.
  • Go to Allow less secure apps and choose “Allow” to let less secure apps access your Google account. We don’t recommend this option because it may make it easier for someone to gain access to your account. But some cases where you still might want to allow apps access include:

If you want to continue using an app you’re familiar with. For example, if you have a Samsung phone and check your email messages with the app that came on the phone, you can choose “Allow” to continue using it.

2-Step Verification is not supported by the app
Many apps, such as the Mail app in some versions of iOS and Windows phones, do not support 2-Step Verification. Instead, you’ll have to create an application specific password to sign in to your account. Visit Problems signing in with 2-Step verification? for instructions on how to use 2-Step Verification on your specific app or device.

Still having trouble signing in?
If you’ve tried all the options above but are still unable to sign in to your account on the app, try the following:

  1. Go to https://accounts.google.com/DisplayUnlockCaptcha on your device’s browser.
  2. Enter your username and password, then type the letters on the screen.
  3. Go back to the app and try signing in again.

What is 5G?

What-is-5G-smartphoneJust five years after the first 4G smartphone hit the market, the wireless industry is already preparing for 5G.

Each of the four nationwide cell phone carriers, as well as smartphone chipmakers and the major network equipment companies are working on developing 5G network technology for their customers.

There are many significant hurdles that all the industry players have to clear before you’ll see a little 5G symbol next to the signal bars on your smartphone screen. For example, it has yet to be determined what 5G even means, let alone what it will look like and when it will get here.

But as consumers use up rapidly growing amounts of 4G bandwidth watching streaming videos on their phones, 5G will soon become a necessity. As telecom engineers work furiously to develop 5G technology, we’re getting a clearer picture of the who, what, where, when and why of 5G.

What is 5G?What-is-5G

The “G” in 3G, 4G and 5G stands for “generation.” So 5G will be the fifth generation of wireless network technology.
The standards for 5G have not yet been set. According to Bill Smith, president of AT&T’s (T, Tech30) network operations, 5G will likely be defined in 2018, and the standards for 5G will codified sometime in 2019 by the standards-setting International Telecommunication Union, a branch of the United Nations. The standards will determine which wireless technologies can be called “5G,” as well as what its characteristics must include, such as how fast it will be.
Still, it’s possible to make a very educated guess about what 5G will look like based on the emerging 5G technologies that the wireless industry is experimenting with.
Here’s the elevator pitch: 5G will be faster, smarter and less power-hungry than 4G, enabling a slew of new wireless gadgets. 5G will let us have faster smartphones, more smart-home devices and longer-lasting wearable gizmos.

How fast will 5G be?How-fast-will-5G-be

5G has the potential to offer speeds up to 40 times faster than 4G — fast enough to stream “8K” video in 3-D or download a 3-D movie in about 6 seconds (on 4G, it would take 6 minutes).
Unfortunately for consumers, there’s a difference between lab experiments and reality. Peak speeds are fun to dream about, but in the real world, actual speeds are much slower than promised.
Nokia (NOK), one of the biggest 5G players, believes that its 5G technology will allow for real-world speeds of about 100 Megabits per second when the network is most congested — that’s about four times faster than 4G’s top speed.
Another characteristic of 5G is that it will have ultra-low latency, meaning that it could drastically reduce the amount of time it takes for the network to respond to your commands. That could give the appearance of much faster loading websites, apps, videos and messages.

How will it work?How-will-it-work

A lot of the wireless companies’ 5G experimentation is taking place in super-high frequencies — as high as 73,000 MHz. Today’s cell phone networks broadcast signal in a range of 700 MHz to 3,500 MHz.
The advantage of high-frequency signals is that they’re capable of providing significantly faster data speeds. The disadvantage is that they travel much shorter distances and they can’t easily penetrate walls. That means thousands — perhaps even millions — of mini cell towers, or “small cells” would need to be placed on top of every lamp post, every building, inside every home and potentially every room.
That presents a host of problems. How can cell phone companies possibly process all that data? There are companies, such as Google’s recently acquired Alpental, that are working on those “backhaul” issues. But they’re not so close to a solution, according to Akshay Sharma, wireless infrastructure analyst at Gartner.
That’s why 5G might complement 4G, rather than outright replace it. In buildings and in crowded areas, 5G might provide a speed boost. But when you’re driving down the highway, 4G could be your only option — at least for a while.

When is 5G coming?When-is-5G-coming

None of these questions are going to be answered any time soon. The industry’s consensus is that it will run 5G experiments in South Korea during the 2018 Winter Olympics, with mass deployments beginning sometime in 2020.
Yet Verizon (VZ, Tech30) has said that it is working on 5G technology with the aim of bringing it to market much sooner — as early as 2017.
With all the questions surrounding 5G and all the wrinkles that need to be ironed out, it’s exceedingly unlikely that anything Verizon does will be widely deployed. For example, the smartphone makers will need to develop chips that are capable of sending and receiving 5G signal without driving costs significantly higher.

Facebook, WhatsApp most popular apps in India

Facebook,-WhatsApp-most-popSocial networking giant Facebook and mobile messaging service WhatsApp have retained their positions as the ‘most popular applications’ among Indians this year, says a new report.

Besides, Truecaller and UC Browser also figure among the top-five most popular mobile applications among Indians, as per the study conducted by WhichApp, a mobile app that helps users discover new applications that their friends use.

WhichApp, which said that more than 20 thousand apps have been discovered and downloaded via its platform, also named MX Player, Flipkart, Candy Crush, Applock and Naukri.com as other popular apps among Indians.

The popularity has been decided on the basis of the number of WhichApp users having and actively using the apps on their mobile phones. Only those apps have been taken into account which have been used at least once a month.

“Our future plans are to localize for vernacular languages for the non-English speaking audience and rollout in other countries as the app is only available in India right now,” WhichApp co-Founder and CEO Kapil Chawla said.

“The aim is to have 10 million users by December 2016,” he added. Currently, it has 100,000 users in the country.

IBM to acquire Merge Healthcare in $1 billion deal

IBM-to-acquire-Merge-Healthcare-in-$1-billion-dealIBM said it would buy medical image company Merge Healthcare in a $1 billion deal and combine it with its newly formed health analytics unit, which is powered by its famous Watson supercomputer.

IBM plans to combine data and images from Merge Healthcare’s medical imaging management platform with Watson’s cloud-based healthcare computing system.

The system analyzes high volumes of data, understands complex questions posed in natural language and proposes evidence-based answers.

The deal will help physicians and researchers collate and analyze data such as patient’s medical and family history, data on others with similar symptoms and clinical research, trials and outcomes.

“Imaging is central to effective diagnosis and treatment…but it is increasingly important to share these images between providers to deliver high quality, cost-effective care,” Dougherty and Co analyst Brooks O’Neil wrote in a note.

IBM has been expanding aggressively in the healthcare IT sector. The Merge deal is the company’s third major health-related acquisition since launching the Watson Health unit in April.

“Organically, we will continue to build and invest from a research perspective in core technologies,” said Stephen Gold, vice president, IBM Watson.

“We will compliment and supplement that with acquisitions,” Gold told Reuters.

With this acquisition IBM will get access 7,500 US healthcare sites.

Merge Healthcare shareholders will get $7.13 per share at a premium of 31.8% to Wednesday’s close, the companies said.

Merge shares were trading at $7.08 by afternoon. IBM shares were little changed at $156.33.

The equity portion of the offer is valued at $713.1 million, according to Reuters calculations based on 100 million Merge Healthcare shares outstanding as of June 30.

Google, Samsung to issue monthly Android security fixes

Google,-Samsung-to-issue-monthly-Android-security-fixesGoogle and Samsung Electronics will release monthly security fixes for Android phones, a growing target for hackers, after the disclosure of a bug designed to attack the world’s most popular mobile operating system.

As of now, Android manufacturers get a monthly bulletin from Google in the form of point updates about security issues. However, Google will release these to the public through the Android open-source project; Nexus and Samsung users will receive security patches faster.

The first update from Google, which is already rolling out to Nexus devices (including Nexus 4, Nexus 5, Nexus 6, Nexus 7, Nexus 9, Nexus 10 and Nexus Player) is aimed at fixing libStageFright issue — the security vulnerability that allows for remote code execution through text message.

Google has further said that it will offer major updates to Nexus devices for two years and provide security patches for three years “or 18 months from last sale of the device via the Google Store.”

However, Samsung did not provide such details about its security programme.

Facebook India goes to users to keep Internet.org alive

Facebook-India-goes-to-users-to-keep-Internet.org-aliveFacebook is mustering support of its users in India to defend its platform Internet.org, with just a week left for public comments on a DoT panel’s report, which says free internet services like that of the social network’s violate net neutrality principle.

Facebook has started the public campaign to make a case before lawmakers for allowing free internet access platforms like Internet.org.

Facebook users in India are getting a message on their profile pages which seeks their opinion on having free basic online services in the country.

“Do you want India to have free basic online services? The mission of Internet.org is to get everyone in the world online. Show your support for free basic online services in India,” says the message, which pops up on a Facebook user’s homepage.

“Soon India will decide on the future of services like Internet.org. Please comment on this post today to help us tell your MPs that you want to connect everyone in India. ?#?connectindia? ?#?connecttheworld,” the message says further.

Many MPs, including Prime Minister Narendra Modi, Finance Minister Arun Jaitley, Telecom Minister Ravi Shankar Prasad and most of cabinet ministers, have their Facebook pages.

By end of June, Facebook had over 125 million users in the country.

The DoT panel’s report on net neutrality, which has been placed on MyGov website for public comments till August 15, has received just over 500 views against over 10 lakh messages that were sent to regulator TRAI through an online campaign in support of implementing ideal net neutrality in India.

Net neutrality implies that equal treatment be accorded to all Internet traffic and no priority be given to an entity or company based on payment to content or service providers such as telecom companies, which is seen as discriminatory.

The DoT panel has opposed projects like Facebook’s Internet.org which allow access to certain websites without mobile data charges. The data charges are borne by the websites or service provider.
