High tech glasses help visually impaired people to 'see'

A team of researchers at the University of Oxford (UK) is in the process of developing and perfecting intelligent eyewear, using microscopes and a pocket calculator to help foreclosure warnings. blind people.

That means visually-impaired people can easily master the road, even to crowded public places such as shopping malls and train stations. Even so, this lens allows them to ' read ' the bus number and the numbers displayed on the cash register.

Light weight and especially low cost, this high-tech glass can appear on the market in 2014 if all trials are successful.

Due to the use of compact cameras and compact pocket computers, this type of electronic goggles is completely designed like the conventional glasses. It is important that its selling price is less than £ 1,000. This price is acceptable for a high tech device, very useful.

Professor Stephen, a neuroscientist who works on the electronic project funded by the British Ministry of Health, says: " The truth is that sooner or later, cheap glasses will help people with impaired vision. It's easier to experience life . ' At present, Professor Kick has completed basic research and is conducting the production of test products.

Many small lenses are mounted on transparent lenses, while mini cameras are integrated at the top of the rim. Cameras that collect information about obstacles or people appear in front of them, then send them to a small computer via a mobile phone.

After receiving the information, the computer simplifies the information into dot signals. The LEDs on the lens emit light signals transmitted from the computer, to inform the blind, so they can know what is appearing in front.

This technology requires the visually impaired to understand the lighting requirements of the LED, such as just a bright light means that a person appears ahead in a certain distance.

In addition, the camera can record bus numbers or train information. This information will be analyzed by the computer and then transferred to headphones that emit sound for the blind. This process is similar for identifying multiple numbers on an electronic screen.
