Seeing is believing, unless youre blind or visually impaired. To this group, the National Institute of Standards and Technology (NIST) says, "feeling is believing."
Computer scientists and engineers at NIST have created a tactile graphic display that brings electronic images to the blind and visually impaired in the same way that Braille makes words readable.
The new imaging device was developed at NIST by the same research team that recently created an electronic Braille reader. The reader translates text from sources such as electronic books into Braille.
According to its designers, the prototype graphic display conveys scanned illustrations, map outlines or other graphical images to the fingertips, and can translate images displayed on Internet Web pages or in electronic books. It uses refreshable tactile graphic display technology, allowing a person to feel a succession of images on a reusable surface.

Researchers create new technique for manipulating polarization of terahertz radiation
20.07.2017 | Brown University
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
