A pair of “smart glasses” could help blind people navigate through an unfamiliar environment by recognizing objects and scoring them, scientists say.
The majority of registered blind people are able to perceive a little light and movement, but no additional accessories is not.
Now researchers at the University of Oxford in England are developing a set of complex points, using cameras and software to detect objects and display them on the glasses lens. The team recently received the Brian Mercer Award for Innovation from the Royal Society of the size of 50 thousand pounds and is about to invest this money in upgrading points.
This intelligent work as points: two small camera mounted at the corners of glass capture different images, just as is done by human eyes. Points represent the information obtained from the cameras, LED displays on transparent lenses, so that the owner can see the enhanced image, using their remaining vision. Relative distance between the cameras shows how far the object is from the user.
Headphones receive text and translate it into speech, to set the direction, or simply read aloud. Points are also equipped with a compass, GPS, gyroscope, a device which responds to changes in the angles of orientation points.
In the United Kingdom, which conducted the study, more than 2 million people have visual impairment and more than 300 thousand registered as blind due to diseases such as glaucoma, macular degeneration and diabetic retinopathy.
In the future, researchers hope to develop a software that provides a wide range of different functions as points testers say that it would be very useful.
For example, to use luminance levels glasses showing depth. So that they can detect the presence of a person on the basis of its motion. In addition to the glasses were able to locate the bus or read his number and dictate the direction of the GPS through headphones.
