Smart Electronic Walking Stick for the Blind People

Abstract

The Smart Electronic Stick (Smart E-Stick) is a clever device that blends sophisticated technology to help persons with vision impairments navigate more easily. The stick has an ultrasonic sensor that identifies obstacles as well as light and water sensors that alert the user to potential hazards. The data collected by the sensors is sent to a microprocessor, which analyses the proximity of the obstacle and, if necessary, activates a buzzer. The stick also has haptic vibrations to warn the user of water and pit holes, as well as the ability to detect if the surroundings is bright or dark. The device includes a wireless RF remote control that can activate a buzzer on the stick to assist the blind person in finding the stick if it becomes misplaced. As a result, visually challenged people can use the stick to easily identify obstacles and find their misplaced gadget. On an Android phone, the “Speak for me” app is also used to generate voice messages for the user.
