Our final project for the course consists of a wearable device to provide aid for the visually impaired. An ultrasonic distance sensor located on a hat collects data of the surrounding environment scanning the area ahead of the user, and uses this data to give an audio feedback through stereo headphones. Using the principles of human sound localization this feedback provides information on the location and distance of the obstacles around the user by changing the angle and intensity of the sound produced. The goal of this project was to create a device that would help visually impaired people to move around with more ease, helping them place walls, doorways and obstacles sooner than they would if they were using only a walking stick.
