Thumbnail track pad

April 17, 2015 7:36 am | by Larry Hardesty, MIT News Office | Videos | Comments

Researchers are developing a new wearable device that turns the user’s thumbnail into a miniature wireless track pad. They envision that the technology could let users control wireless devices when their hands are full: answering the phone while cooking, for instance. It could also augment other interfaces, allowing someone texting on a cellphone, say, to toggle between symbol sets without interrupting his or her typing.

Camera chip provides superfine 3-D resolution

April 6, 2015 8:00 am | by Jessica Stoller-Conrad, Caltech | News | Comments

Imagine you need to have an almost exact copy of an object. Now imagine that you can just pull your smartphone out of your pocket, take a snapshot with its integrated 3-D imager, send it to your 3-D printer and, within minutes, you have reproduced a replica accurate to within microns of the original object. This feat may soon be possible because of a new, tiny high-resolution 3-D imager developed at Caltech.

Nanoscale speed bump could regulate plasmons for high-speed data flow

April 1, 2015 12:08 pm | by Mark Esser, NIST | News | Comments

The name sounds like something Marvin the Martian might have built, but the “nanomechanical plasmonic phase modulator” is not a doomsday device. Developed by a team of government and university researchers, including physicists from NIST, the innovation harnesses tiny electron waves called plasmons. It’s a step towards enabling computers to process information hundreds of times faster than today’s machines.

Quantum teleportation on a chip

The core circuits of quantum teleportation, which generate and detect quantum entanglement, have been successfully integrated into a photonic chip by an international team of scientists from the universities of Bristol, Tokyo, Southampton and NTT Device Technology Laboratories. These results pave the way to developing ultra-high-speed quantum computers and strengthening the security of communication.

Video gamers may learn visual tasks more quickly

April 1, 2015 8:44 am | by David Orenstein, Brown Univ. | News | Comments

Many studies show that video gamers perform better than non-gamers on certain visual tasks, like managing distractors and identifying targets, but a small new Brown Univ. study provides gamers with some cognitive bonus points. The study results suggest that gaming not only improves their visual skill but also may improve their learning ability for those skills.

Team discovers new liquid crystal configurations

April 1, 2015 8:08 am | by Evan Lerner, Univ. of Pennsylvania | News | Comments

Oil-based liquid crystals are ubiquitous; an understanding of their properties is behind the displays in most electronics. Water-based liquid crystals are less well understood, though their biocompatibility makes them a candidate for a variety of applications. New research has advanced the field's understanding of these materials, demonstrating never-before-seen configurations by confining a water-based liquid crystal in a cylinder.

Wearable technology can help with public speaking

March 31, 2015 8:34 am | by Leonor Sierra, Univ. of Rochester | Videos | Comments

Speaking in public is the top fear for many people. Now, researchers from the Human-Computer Interaction Group at the Univ. of Rochester have developed an intelligent user interface for “smart glasses” that gives real-time feedback to the speaker on volume modulation and speaking rate, while being minimally distracting.

March 30, 2015 11:38 am | by George Hunka, Tel Aviv Univ. | News | Comments

From smartphones and tablets to computer monitors and interactive TV screens, electronic displays are everywhere. As the demand for instant, constant communication grows, so too does the urgency for more convenient portable devices, especially devices, like computer displays, that can be easily rolled up and put away, rather than requiring a flat surface for storage and transportation.

Manufacturing process could yield better solar cells, faster chips

March 25, 2015 10:57 am | by Tom Abate, Stanford Engineering | Videos | Comments

Computer chips, solar cells and other electronic devices have traditionally been based on silicon, the most famous of the semiconductors, that special class of materials whose unique electronic properties can be manipulated to turn electricity on and off the way faucets control the flow of water. There are other semiconductors. Gallium arsenide is one such material and it has certain technical advantages over silicon.

“Virtual nose” may reduce simulator sickness in video games

March 25, 2015 7:50 am | by Emil Venere, Purdue Univ. | News | Comments

Virtual reality games often cause simulator sickness, but new research findings point to a potential strategy to ease the affliction. Various physiological systems govern the onset of simulator sickness: a person's overall sense of touch and position, or the somatosensory system; liquid-filled tubes in the ear called the vestibular system; and the oculumotor system, or muscles that control eye movements.

New technology may double radio frequency data capacity

March 13, 2015 3:34 pm | by Holy Evarts, Columbia Univ. School of Engineering and Applied Science | News | Comments

A team of Columbia Engineering researchers has invented a technology, full-duplex radio integrated circuits (ICs), that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times or at the same time but at different frequencies.
