Digital Guide Glasses for guiding the blind
It is indeed a great misery and tragedy to be blind and in this present world where things have become so complicated with the advent of so many technologies, it is difficult for blind individuals to do their daily rituals in cities bustling with rushing crowds and a never ending traffic line. But the modern technology has also done many advances in the field of medicine and development of the medical aids.Now, the blind personal may not need to carry pets or walking canes with themselves as guides to wherever they go. Thanks to the Smart specs that replace white canes and guide dogs for some blind people in two years, say a researcher. The hi-tech glasses have been designed to help prevent “legally blind” people to bump into things while they are on the go.
These glasses use tiny stereo cameras in-built in their frames to project simplified images onto the lenses which become brighter as the object moves closer. In January, 2013 the glasses shall be subject to a series of trials involving 160 people with severely impaired sight in Oxford and London. The developer of these glasses, Dr Stephen Hicks, from Oxford University hoped that a finished model would be commercially available in around two years. The cost of these glasses is expected to be around £600 much lesser than a guide dog or any such assistance. Dr. Hicks also made it clear that the spectacles were designed as a navigational aid, and cannot restore lost vision, he was also quoted, saying:
The glasses work using a pair of cameras that determine the distance of objects and we simply translate that into a light display, this is not restoring sight, but we can improve spatial awareness.
Research has shown that fewer than half of people who are legally blind attempt to leave their homes on a daily basis. The aim is to increase the independence of the hundreds of thousands of people who are visually impaired in the UK.
He also added that the volunteers in trails, trying out these glasses were able to master them within a few minutes.
People were able to recognise where a table was, where a wall was, and when a person was five metres away.
These glasses could really make in big difference in the life of blind people by decreasing their dependence on others and objects and make them more self-reliant.
