Blind people have to memorize their route and feel out the environment by hearing, but weather conditions like storm, rain or snow complicate their sense of locality. In addition, costly guide dogs often have trouble concentrating in urban environments for more than 2-3 hours.
This disability aid, based on the traditional white cane, is equipped with sensors and a PMD-camera which is able to measure the 3rd dimension directly in real time, while communicating with a processor processing data on the environment. The processed information is converted into auditory feedback in a head set worn by the user. In addition, the device has a hub motor in a wheel, constantly providing the user with information about the terrain.
