The skin on Your forearm could be 'Touchpad'

A team of scientists has developed a new technology that can make the skin on your arms and hands act like a touchpad for smartwatch. The technology, known as SkinTrack, developed by the Futures Interface Group, a research lab at Carnegie Mellon University.

This technology requires the user to wear rings and sensors attached to a rope smartwatch. The sensor has four electrodes, which used to receive high frequency electrical signals emitted by the ring when a finger touches the skin, to calculate the exact position of the finger.

This technology also enables the user to swipe and press the arms to interact with smartwatch, and even allows users to paint a picture in the arm. This technology also transcends the limitations of a small smartphone screen to allow users to drag the app out smartwatch and place them on the whole arm. 

Skintrack also can understand the hot key commands, thus enabling its users to mute incoming calls by simply writing 'S' on the arm or trace an "N" on your hand to open up your news app. SkinTrack can even track your finger when it’s hovering above the skin.
As quoted by The Verge, the Futures Interface Group has the plans to commercialize this technology. Currently, the team is working on ways of supplying constant power to the ring, to keep the signal remains stable when the body is in constant motion. Meanwhile, the team stressed that this technology poses no danger to the human body. *** [EKA | FROM VARIOUS SOURCES | THE VERGE]

People took more time for Facebook' rather than socializing within a day

How much time is spent by the person to open the Facebook in a day? According to the CEO of Facebook, Mark Zuckerberg, the figure was turned out to be quite longer, almost 1 hour. On the same time also applies to other applications owned by Facebook, namely Instagram and an instant messaging service, Messenger.
According to Mark Zuckerberg, the Users average 50 minutes per day on Facebook, Messenger and Instagram. (Picture from: http://adf.ly/1a0Sbe)
"Today, people around the world spend an average of 50 minutes per day to use Facebook, Instagram, and the Messenger," Zuckerberg said in the Facebook's financial report first quarter of 2016, as summarized from TechCrunch on Thursday, April 28, 2016. Zuckerberg insists that the 50 minutes it does not include the time spent to access other popular services of Facebook, ie WhatsApp.

"People" is meant by Zuckerberg is the user of the three such services globally. For Facebook, the number reached 1.65 billion. For Instagram registered 400 million users, while the Messenger 900 million.

More longer than the socializing time
For the record, the 50 minutes it turned out to be longer than the time spent by Americans for socializing. According to the Bureau of Labor Statistics, in 2014, the Americans (ages 25-54 years old and have kids) on average only spend 43 minutes each day to do social activities such as visiting friends or attending an event, etc.

In the same occasion, Zuckerberg also reveals that to this year's Facebook profit more than tripled compared to the previous year, ie 1.51 billion dollars. And the Facebook stock prices also recorded an increase of 9 percent in the session after the publication of the financial statements of the social networking company. *** [EKA | FROM VARIOUS SOURCES | TECHCRUNCH]

Researchers have developed a flexible smartphone that can be bent

Researchers at Queen's University, Kingston, Ontario said that they've developed a smartphone that can be bent. This phone is named Reflex, a phone with a high resolution color screen, and has multi touch technology and the most special is the "input bend" technology, ie the phone can be controlled by means of bending it.

Roel Vertegaal, Director of the Human Media Lab at Queen's University said that the interaction between humans and computers will be a lot of change with the Reflex. He continued that, the real innovation is, from now on we can think about computer science and software and their interactions in three dimensions.

Screen that can be bent is in fact not found by Vertegaal and his team, but they use it to help them envision the future of computers. According to Vertegaal, he and his team used the screen and then think about what can be done with the screen in the context of the interaction between humans and computers.

The team, consisting eight researchers have already adapted the flexible display into a phone prototype that can be bent like a book bent to turn the page. With such capabilities, Vertegaal said that this opens up new possibilities that can be achieved by a computer.
Vertegaal predicted, the flexible smartphones like the Reflex can now be used by consumers in the next five years. *** [EKA | FROM VARIOUS SOURCES | SCIENCEDAILY]

The passive WiFi use less power

In the era of internet, WiFi is everywhere, providing remote wireless access to the Internet, and save us tripping over the cables. However, WiFi consumes a lot of energy, and the battery drain connected devices very quickly. Fortunately, engineers from the University of Washington (UW) is ready to save! They discovered a technique that enables WiFi uses 10,000 times less energy than normal.

The latest passive WiFi is also consumes 1,000 times less power, compared to Bluetooth. In fact, compared with conventional methods, this new technology uses almost none of power at all. Although currently only able to transmit data at rates of up to 11 Mbps (megabits per second), far lower than the peak of WiFi speed, which is the data transfer rate is 11 times higher than Bluetooth.

This discovery proves the concept of research that was built with a technique called backscattering WiFi, where the signals sent between a Wi-Fi router and a wireless receiver device manipulated. A previous study by UW showed that low power equipment can be used to reflect and "distort" this signal. Devices that are connected to receive a new distortion as unique data.

The passive WiFi is an evolution of the technique. First, connect to the Internet made only one, which is installed in the router, which is out of traditional Wi-Fi signal. Wi-Fi Sensor Passive reflect and absorb the signal, creating multiple streams of data that can be "bounced" against some of the receiving device.

"Our sensors can communicate with each router, smartphone, tablet or other electronic devices with WiFi chipsets," said Bryce Kellogg, a doctoral candidate student in electrical engineering at UW and co-author of the study, said in a statement.
"Cool part is that all of these devices can decode WiFi package that we made use of reflection, so you do not need any special equipment," said Kellogg. *** [EKA | FROM VARIOUS SOURCES | WASHINGTON EDU | ENGINEERING.COM]

This new storage media can accommodate as many as 360 TB of data

One of the challenges in the development of the computing world is the creation of large-capacity storage media and can last long.

To answer that challenge, researchers from the University of Southampton has recently managed to create a new storage medium that is otherwise capable of storing up to 360 TB and can last up to 13.8 billion years old.
The new technology of storage media called '5D' developed by University of Southampton, can accommodate as many as 360 TB of data. (Picture from: http://adf.ly/1XCLeZ)
It is a technology called '5D' and uses nanostructured glass as a medium. Interestingly, to obtain a capacity of 360 TB, scientists only need a nanostructured glass and has a size of a coin.

The storage media is also said to be very tough. It can withstand the heat of the flame to a temperature of 1,000 degrees Celsius and freezing conditions up to minus 190 degrees celsius.

The technique used involves a laser with a very high degree of precision, ie to a count of femtoseconds, or 1/1,000 trillion second intervals. The file is stored is written in three layers of blocks spaced 5 microns or 0.005 mm.

So far, some important documents had been 'immortalized' in a new storage media, namely the Universal Declaration of Human Rights, Magna Carta, and the King James Bible. *** [EKA | FROM VARIOUS SOURCES | ]
