“A pair of “smart glasses” might help people with visual impairments navigate an unfamiliar environment by recognising objects or translating signs into speech, scientists say.
The majority of registered blind people have some residual ability to perceive light and motion. But assistive technologies for the visually impaired have been limited.
Now, researchers from Oxford University in England are developing a set of sophisticated glasses that use cameras and software to detect objects and display them on the lenses of glasses.
Here’s how the smart glasses work: Two small cameras mounted on the corners of the glasses capture two different pictures, just as human eyes do. The spectacles display information from the cameras on transparent LED displays on the lenses, so the wearer can see an enhanced image as well as use their remaining sight. Comparing the distance between the cameras reveals how far the object is from the wearer.
A set of headphones takes text and translates it into speech to provide directions or read signs aloud.
The glasses are also equipped with a compass, a GPS and a gyroscope, a tool that measures the orientation of the glasses”
