UCLA is testing a brain implant that takes the images captured by a tiny camera and converts them into electrical impulses that stimulate the part of the brain responsible for sight. It helps blind people detect darkness and lightness, as well as sensing motion.
The weWALK is a smart cane for blind pedestrians, with ultrasonic sensors to detect obstacles ahead and Google Maps connections to navigate through and describe the surrounding area.
The busiest part of the year for travelers is coming, meaning that at airports, there will be a lot of people around to clonk into each other. Researchers at Carnegie Mellon University may have a solution: a collision-detecting suitcase.
