Release date: 2017-02-04 A device developed by researchers at the University of Melbourne recently will significantly improve the daily lives of blind or visually impaired people. They have developed an electronic prototype that can help these people avoid non-prominent obstacles. The device can be attached to a cane, walker or wheelchair, using lasers and cameras to find non-prominent potentially harmful obstacles such as curbs, caves, descending stairs, etc. Associate Professor Elaine Wong from the Department of Electrical and Electronic Engineering at the University of Melbourne, Professor Marimuthu Palaniswami and Dr. Aravinda Sridhara Rao combined their respective advantages in smart sensors, scanning technology and optics to develop the non-portable laser optics they wanted. Associate Professor Wong said: "When this equipment is fully developed, it will be a guard against falling, and falling is a major problem for the elderly." She contacted the Australian Visually Impaired Association and provided them with her engineering skills, hoping to help improve the independence and safety of the visually impaired. “I want to do something that really has an impact, and improving people’s quality of life will be very important.†The next step for the research team is to miniaturize the device and optimize the laser source to work in all light conditions. They also hope to make the device as cheap, portable and convenient as possible, enabling it to help 360,000 visually impaired people in Australia and 285 million visually impaired people worldwide. “Although the advantages of this device in real-time navigation and escort safety are obvious, the social benefits it will bring to the visually impaired can not be underestimated, because it can keep these people in contact with society, ensure their safety and Confidence and skill in dealing with people," said Associate Professor Wong.
