Smart glasses that play a specific noise when an object comes into their field of view, such as the sound of a page turning to represent a book, enable people who are blind to locate that item
Smart glasses that emit a sound when an object comes into their field of view could help people who are blind to locate certain items.This involves them sending out a noise that bounces off objects in their vicinity, with the returning echoes giving information about their surrounding area.at the University of Technology Sydney in Australia and his colleagues wanted to create glasses that similarly give people information about what objects are close to them.
The team programmed a sound to play from the speakers when one of the objects came into the glasses’ field of view as a wearer scanned their head around a room. Each of the objects was assigned a corresponding sound. For example, when a book came into view, the wearer heard a page turning.of light perception and seven people with no sight issues who were blindfolded. They were all sat at a table with the four objects arranged on top.
The team also found that the participants who were blind or had low vision experienced no extra cognitive workload, assessed via a questionnaire, while wearing the glasses compared with at the beginning of the study, which suggests that the glasses were relatively easy to adapt to. The researchers now hope to develop this technology to recognise more objects and to allow people to use it while they are walking around.
