Students at the Technion – Israel Institute of Technology have created a system for the visually impaired that detects obstacles and uses audio messages and signals to alert users before a collision.The “seeing app,” developed by Tzahi Simkin, Gal Dalal and Danny Zilber, uses a Kinect 3D camera, a computer and an Android phone for audio interaction. They adapted the Kinect to feed its images into a mini-PC, where the images are analyzed. The system determines if there are objects or obstacles in the path of the camera, how close they are, and how far to the left or right the user must move to avoid them. That data is analyzed and a sound interface directs an Android device, using voice commands or a series of beeps to guide the user around obstacles.
