---- PROTOTYPE --------- PURPOSE: To design a prototype of goggles that assist individuals who have low vision to navigate. Researchers at the Universidad Carlos III in Madrid, Spain have developed a pair of ultrasonic goggles that are intended to make it safer and easier for people who have low vision to get around. Individuals with partial sight experience "Terminator-style vision" through the use of two cameras mounted onto a virtual reality headset that is then connected to a small computer. The device scans the area that lies in front of the wearer and displays relevant information concerning the scene in the form of color-coded outlines that allow the user to know the distance and the shape of objects which are traditionally difficult to see or interpret. The device detects objects and people who move within the visual field that a person with no visual disabilities has. Often, the unaided user will not detect these objects due to problems of contrast. Testing is being currently being done within a group of sample patients, and results will be available by the end of 2012 and will be used to improve on future models. AUTHOR: Edwin Kee.
