Sonar Walking Stick

The ability to aid the visually impaired is a field that has the potential to advance itself with the improvement of technology. Many of these products that assist those in need can cost up to $650, which is an expense that not everybody in need can afford. This means that the technology doesn't get into the hands of all those who need the devices. The sonar walking stick designed in this report, offers a cheaper solution, with a price of under $200, to assist those who need it with the use of the Arduino Mini Pro. The Arduino processes information received from an ultrasonic sensor and outputs object's locations to the user through vibrational motors. This cane will detect objects that are found in the average person's visual focal area and alert the user of their location.
