It seems like the world has been made smaller by the modern internet and smartphone technologies. Yet, for the blind or visually impaired people, those technologies are opening up a whole new wide world.
As iPhones and other smartphones have become increasingly popular, researchers and developers have been working on a variety of new apps that can assist visually-impaired people. As a result, there are numerous applications and tools available for helping blind people. Those applications explain colors, detect motions, text or read for the blind. All of these applications are making the visually impaired more free than before.
However, when the blind or visually impaired people want to go somewhere, they still need assistance like guide dogs. Moreover, for the place where they have never been to, they can hardly think to go out alone, even with a guide dog. As a result they have been restricted from going somewhere freely.
eSound Viewf, a smartphone application designed and being developed by S. Korean undergrads will remove this obstacle for the blind..
The Korean undergraduate student team, eProject Mf from Ulsan National Institute of Science and Technology, proposed to make a smart phone application, which helps the visually impaired to navigate and find their way without delay by an instant and intuitive sound system.
The eSound Viewf will tell which way to go to get to a destination. This system uses the DGPS* navigation system in the smartphone and gyroscope sensor, bluethooth hands-free earphones which measure how accurately the user is making his/her way. It sends a beeping sound to the user to tell whether he/she is going the right way. The eSound Viewf application on smartphone and hands-free earphones exchange data, and communicate through Bluetooth technology,
*DGPS: an enhancement of Global Positioning System that provides improved location accuracy, from the 15-meter nominal GPS accuracy to about 10‡p in case of the best implementations.
The beeping sound becomes louder and faster as the user become farther away from the designated direction. The sound becomes lower and slower as the user moves closer to the designated way and eventually becomes silent when the user is on the right direction
gThe existing system or application tells where to go but canft tell whether he/she is on the right path or how much of a turn he/she should make,h said Donghwan Song, leader of eProject Mf. gThe eSound Viewf can tell the degree of turn he/she should make which existing systems canft do. It tells the degree of accuracy of the turn by the volume and frequency of the beeping sound.h
The team is planning to make this application available to the public by early next year. gThe commercialization of the system will be possible soon, since the application will be completed as soon as the wireless earphones equipped with a gyroscope sensor are developed,h said Song.
gfSound Viewf is the result of hard work and hope of our team,h said another member of the eProject Mf, Youn Jae Lee. gWe want everybody including blind people to walk and go anywhere they want to go.h
eProject Mf consists of ten UNIST students with the guidance of Prof. Namhun Kim from the School of Design and Human Engineering at UNIST. This proposal has been selected and awarded as one of the best proposals at ethe 2013 U(University)-startup contestf organized and supported by the National Research Foundation of Korea and Maeil Business Newspaper, Korea.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
