Abstract The paper here presents the model of a walking stick that alerts visually challenged
people over obstacles by use of electronic sensors and controllers. Very few of the navigation aids
available for visually challenged people can provide dynamic navigation and which work
perfectly for day to day navigation requirements (The white cane and walk dogs are not safe for
today s increasing traffic and insensitive world). This model here demonstrates a system concept
to provide an electronic aid for blind people which would benefit the challenged person for his
daily travelling, whether it be indoors or outdoors. The aim of system is to provide a sense of
artificial vision by alerting the subject about the environmental scenario of static and dynamic
objects around them. In this system, an ultrasonic sensor, an atmega16 controller, a buzzer and a
vibration motor is used.
