O2Amps glasses designed to help read peoples’ emotions find other applications

Along with facial expressions, tell-tale variations in facial blood flow that causes reddening and whitening of the skin can also give an indication of people's emotions. To take advantage of this, 2AI Labs developed a special pair of glasses designed to enhance a person's color vision to better enable them to perceive the oxygenation and hemoglobin variations in another person's face, and thus their emotional state. The glasses are now finding a variety of applications, from medical to security.

Evolutionary neurobiologist Mark Changizi believes that color vision in primates evolved in order for us to detect social cues, emotions and the states of our friends or enemies. When conversing with a person, blushing indicates he/she is embarrassed and if the blood drains from the face, it indicates the person is scared or apprehensive.
Changizi says the human eye is specifically tuned to see blood, and the amount of oxygen in blood, right through the skin. “We can often tell when someone is sick, and even what ails them, merely by looking at them.”
So following this theory, he and his colleagues at 2AI Labs have been developing special glasses to visually enhance for the user oxygenated blood and blood pooling, and thus amplify the social cues that allow us to perceive emotions more clearly. The glasses are called O2Amps (O2 for oxygen, Amp for amplification).
Any product that is designed to help read people’s emotions is likely to find strange bedfellows and the eyewear has already caught the attention of law enforcement. The O2Amp glasses are currently under testing by the U.S Navy, with 2Al labs also testing a pair of mirrored-lensed O2Amps for use by poker players.
The technology is claimed to enhance what our eyes do naturally, by removing noise from the blood signal, giving a clearer view of patients, their health, vitality, and state of mind. So, the spectacles are now also being trialed in a number of innovative medical applications. Because the lenses also enhance detection of what is beneath the skin, they are being used to help nurses identify veins and amplify trauma and bruising that might be invisible to the naked eye.
Allowing people with color blindness to more accurately differentiate colors is another potential application for the O2Amps that has shown promise. The Oxy-Iso version of the glasses has been found to diminish the red-green deficiency that lies behind this perceptual disability. Currently this effort seems to have run into a hitch, however, because the existing glasses also hinder the perception of blues and yellows (which presents a problem for driving).
Despite this limitation, the potential applications for the O2Amps are many and varied. The Changizi O2Amps blog fields questions from individuals that are interested in using the glasses for their own unique purpose. Dating and other social activities make the top of the list, while others have inquired about possible uses in the field of visual arts.
“Indeed, we’ve found lots of interest from artists, although we hadn’t quite anticipated it,” said Dr Changi, who still believes that by far the greatest impact the O2Amps will have is in the medical field. “We’ve received great interest from medical professionals interested in trying out the O2Amp, and we’re moving now to get them in hospitals and among clinical staff everywhere.”
Back in September 2012 Gizmag covered the EnChroma glasses, which were specifically developed to assist people with color blindness. Unlike the O2Amps, the EnChroma sunglasses use a proprietary coating on the lenses and work by selectively reducing the transmission of given wavelengths of light, thus allowing red and green to stand out.
The O2Amps glasses are now available for purchase through the O2Amps website and Amazon for US$297.

Nine government sites hit by cyber attacks: NIC

The National Informatics Center (NIC) has revealed that as many as nine government websites were defaced by recent cyber attacks. The center further said that the servers, which hosts these government sites, suffer a number of hacking attempts on a daily basis. The websites www.kumbh2010haridwar.gov.in, www.ueppcb.uk.gov.in, www.gov.ua.nic.in/ujn, www.cdodoon.gov.in, www.arunachal.nic.in,www.bee-india.nic.in, www.civilsupplieskerala.gov.in, www.mpcb.gov.in and www.informatics.nic.in were  defaced , prompting authorities to  ramp up  the cyber security safeguards. In an RTI reply, the NIC, which reports to the Ministry of Communications and Information Technology, said that it was impossible for the body to accurately quantify these attacks but they are usually blocked by security controls put in place. The Ministry was asked to provide details of hacking attempts made on the governments websites in the last ten years (2001-11) along with url names of the portal...

Google and Stanford early adopters of Honda Fit EV

Honda's first all-electric vehicle is hitting the streets a little early. The  Honda Fit EV  debuted at the Los Angeles Auto Show in November 2011, and it's expected to be     available for lease this summer. However,  Honda announced  that Google and Stanford University got a special early delivery of the tiny EV this week.The Honda Fit EV is equipped with a 20kWh lithium ion battery, and has an EPA estimated driving range of 76 miles. Google added the EV to its  car -sharing service for employees, dubbed the G-Fleet, in    Mountain View, Calif. The search giant maintains several electric and plug-in vehicles that it uses for research and to cart Googlers around town and between buildings on campus. Stanford University also is an early adopter of the Fit EV, but will be using it primarily for research. The university's automotive research department will study the difference in psychological and physical reactions of using battery...

Solar car hits U.S. in round-the-world jaunt

Last October, the SolarWorld GT solar-powered car set out from Darwin, Australia on a drive around the world. It has since driven 3,001 kilometers (1,865 miles) across Australia, logged 1,947 km (1,210 miles) crossing New Zealand and been shipped across the Pacific Ocean. This Friday, it will embark on the U.S. leg of its journey, as it sets out across America from the University of California, Santa Barbara.   The SolarWorld GT is the result of a collaboration between solar panel manufacturer SolarWorld, and Bochum University of Applied Sciences in Germany. The four-wheeled, two-door, two-seat car gathers solar energy through photovoltaic panels built into its roof, with its solar generator offering a peak performance of 823 watts. Custom hub motors are located in both of the front wheels. The vehicle manages an average speed of 50 km/h (31 mph), with a claimed top speed of 100 km/h (62 mph). In order to demonstrate that solar powered cars needn't be a radical...
