Human bodysuit with color sensing for the Visually Impaired

Abstract

In this paper, a navigational aid for blind people is developed as a suite with the handwear module, which makes use of ARM LPC 2148 microcontroller board with ultrasonic serial ASCII sensors and tappers for collision avoidance and a provision for primary-colored objects detection. The user is alerted with tapping mechanism and synthetic voice feedback to guide the navigation. The user is also provided with buttons for switching on the Left and Right-hand wear sensors and sensing primary colors. The user can also turn on and off the GPS and GSM modules, which gives the location of the user through a message to any preloaded number for assisting. Thus the proposed handware module helps the blind people to navigate outdoor and can differentiate primary colored objects that helps user in segregating daily household objects, appliance, clothes, etc. The paper also gives an idea of possible additional provisions to the jacket are explored.
