Infrared goggles can even help wearers navigate in darkness, say researchers
A new device that can help blind people navigate and avoid obstacles was developed by scientists using infrared goggles and an array of vibrating pads on the forearm.
Unlike canes and many other tools commonly available to visually impaired people for navigation, the new device enables the full use of their hands, according to a yet-to-be peer-reviewed study on the device that was posted in the preprint repository arXiv this month.
“The most common tool available to them is the cane. Although the cane allows good detection of objects in the user’s immediate vicinity, it lacks the ability to detect obstacles further away,” researchers Manuel Zahn and Armaghan Ahmad Khan from the Technical University of Munich in Germany wrote in the study.
The new device also does not interfere with the user’s sense of hearing – which is extensively used by the visually impaired – according to the scientists.
It uses a pair of infrared cameras inserted in 3D-printed prototype goggles to capture a stereoscopic image that a small computer uses to create a map of the surrounding area.Continue reading… “SCIENTISTS BUILD NEW DEVICE THAT MAY HELP PEOPLE WHO ARE BLIND ‘SEE’ IN INFRARED”
