Blind guide

In this paper, we present a design of a wearable equipment that helps with the perception of the environment for visually impaired people in both indoor and outdoor mobility and navigation. Our prototype can detect and identify traffic situations such as street crossings, traffic lamps, cars, cyclists, other people and obstacles hanging down from above or placed on the ground. The detection takes place in real time based on input data of sensors and cameras, the mobility of the user is aided with audio signals.
