There have been numerous inventions of new age wearable technology in the last few years. But Scientists at the MI’s Media lab have conceived a device that will raise the bar of the category of wearable technology to new heights.

In what could prove to be the next most powerful wearable for the visually impaired is the new Finger mounted reading device. This device comes with a built-in camera which converts written text into audio for visually impaired users. As a visually impaired user moves her finger across the text, a synthesized voice would read out words and sentences loudly for the user to hear and decipher the text.

MIT media lab post doc Jochen Huber, who is also the lead writer of the paper on this device, said that “For visually impaired users, this is a translation. It’s something that translates whatever the finger is ‘seeing’ to audio.”

The device is being applauded by physicists and scientists already and is being expected to help the Visually impaired people to get some ease in their overall reading experience. George Stetten, a physician and engineer with joint appointments at Carnegie Mellon’s Robotics Institute and the University of Pittsburgh’s Bioengineering Department, who himself is in the way of developing a finger mounting device that gives visually impaired users information about distant objects was quoted  as saying “I am very impressed with what they do.”

The device according to the researchers may have a wider range of applications that they’d expected with its conception. They are planning to cover a range of people apart from the visually impaired ones. “We got many emails and requests from organizations, but also just parents of children with dyslexia, for instance.” said Shilkrot.

The team is now working on developing a version of the open-source software that will run on Android Phones, which are widely used all over the world.

While the MIT team that developed the device feels it will be able to launch the device at an affordable price, there has however been no declaration of the cost of the device as yet.

  • Indulging in smoking or drinking alcohol may not only damage your teeth but also lead to increased incidences of failure in dental fillings, warned researchers.

The findings, led by researchers from the University of Pittsburgh, showed that within two years of the dental procedure, Dental fillings failed more often in patients who drank alcohol, while the overall filling failure rate was higher in men who smoked.

Furthermore, people with a difference in the gene for matrix metalloproteinase (MMP2) — an enzyme found in teeth — were at increased risk of Dental filling failure.

This could be because MMP2 might be able to degrade the bond between the filling and the tooth surface, potentially leading to failure, the researchers said.

The results, published in the journal Frontiers in Medicine, suggest that genetic analysis might help dentists to personalize treatments for their patients, which could lead to improved outcomes.

“A better understanding of individual susceptibility to dental disease and variation in treatment outcomes will allow the dental field to move forward,” said Alexandre Vieira, a researcher from the varsity.

“In the future, genetic information may be used to personalize dental treatments and enhance treatment outcomes,” Vieira added.

For the study, the team from America and Brazil analyzed dental records of 807 patients.
Fillings can fail for a variety of reasons, including re-emergence of the initial tooth decay or the filling becoming detached.

The researchers also examined if newer composite resin Dental fillings are as durable as traditional amalgam fillings, which have been in use for more than 150 years but which contain mercury, a toxic metal.

The researchers found that overall, there were no major differences between patients receiving amalgam or composite Dental fillings in terms of filling failure rates. (IANS)
