Smart glasses will help blind people to see

Some scientists of  Oxford University are developing a smart glass or smart eyewear device , to make thousands of blind people able to see.
This smart glasses will have tiny cameras  in the frame and pocket computers. This devices will  warn the wearer of that smart eyewear device if any person or other objects in front of him.

The smart glasses will work using a pair of cameras.  These cameras  will determine the distance of objects and we simply
translate that into a light display. For this the cameras will capture the information of objects covered by the eyesight  of the user and will send it to the pocket sized mobile computer. That camera will be in the users pocket. The computer will then process the information and will simplify it into a certain pattern. These smart eyewear devices will also have light-emitting diodes (LED)  in the lens. The information that the computer processed will then be sent to the lances. Then the LED  on the lances will be lights up creating form of the pattern. This way this smart eyewear device will notify the user about the objects in front of him.

Actually this smart glasses will not restore sight. It will just but improve spatial awareness of the blind people. The smart eyewear devices were designed as a navigational aid, not to restore lost vision.
Around 300,000 people in the UK are registered as legally blind. Of these, 90 percent of this people have  some residual vision. They can  detect blurry shapes and differences between light and dark.
The aim of this smart eyewear device is to increase the independence of the hundreds of thousands this types of people who are visually impaired.
Wearing this smart glasses people will be able to recognize where a table was, where a wall, and  a person from five meters away.
This smart eyewear device  could also provide many expanded functions, such as  scanning barcodes to display the prices of shop items, or reading printed words out loud via an earpiece,
Or exploring the shopping mall or a busy railway station or reading bus numbers and the numbers listed at the ATM machine.
This smart glasses are still in development. Developer Dr Stephen Hicks, from Oxford University, hoped that  finished model of this smart eyewear device will be commercially available in around two years, at the early 2014. The cost will nearly  be around £600 .
