Abstract: There has been a great deal of research in the area of motional aids for the visually challenged and impaired. Smart systems have been proposed for ease of use and greater accuracy. The current paper proposes a smart system to aid visually challenged people in traversing obstacle-filled paths. The solution uses an Arduino board paired with ultrasonic sensor for implementation of the system, which is augmented by the addition of a piezoelectric speaker and variable intensity vibration motor.
