Abstract
In this paper, a smart cane can help visually impaired people to detect the obstacles around them is designed and implemented. A PCB board uses a microcontroller to get data from ultrasonic sensors to determine the distance from the cane to the nearest obstacles. This distance information will be transferred to the Android smart phone via Bluetooth protocol. Whenever user is walking to an area where having obstacles around and the distance between user and obstacle is shorter than a predefined threshold, the phone will display distance and give warning by speaking that value in centimeter unit while the vibration motor attached to the cane will vibrate with the intensity in inversely proportional with the value of the distance.
