Echo

The design was made to solve the problem of blind people.Most of them use a white cane to move around, but the range with that tool is limited by about 1.5 meters. This design is made to push the distance in which the blind person can sense objects. It has an ultrasonic sensor to measure the distance between the user and the object in front of him. After the distance is measured the information will be given to a user via headphones. Also, in theory by turning the head the person can identify different objects such as doors, stairs, curb etc.
