People who are blind would either use a white mobility cane or a guide dog to get around. If they have to use a walker, the walker could bump into objects or slip off curbs or steps because they are no longer are able to determine what is in front of them. So that means, if they had a surgery or injury or something else that would cause the need for a walker, it would be very hard to get around independently. Your task would be to create a solution for blind people to get around safely and independently if they are using a walker either temporarily or more permanently.
