摘要：One of the most challenging problems for visually impaired people is navigation. Usually they have to be dependent on other people to navigate their way. A wearable navigation system which can determine the obstacles and drop-offs can help blind people to walk with confidence even in unfamiliar outdoor environments. Many electronic travel aids have been developed recently to help them navigate independently even in unfamiliar or changing environments. Here, we propose an intuitive, economic and wearable device which focuses on removing the mobility problems of visually impaired people and thus replace the commonly used white cane.
