Among all the disabilities, blindness and deafness are the most common disabilities across the world. According to latest statistics of World Health Organization, 285 million people are visually impaired whereas 360 million people have disabling hearing loss [1]. Blind and deaf people face many problems in their daily life. And walking safely and confidently without human assistance in unfamiliar environment is very difficult for them. In this paper we propose an advanced blind stick that allows deaf blind people to navigate with ease using advanced technology. The designed blind stick not only detects obstacles like objects, water but also produce vibratory mechanism to aware person holding the stick. In this proposed project, ultrasonic sensors are integrated in stick which detects obstacles ahead using ultrasonic waves. The blind and deaf people can see the obstacles by using the smart walking cane with vibrating mechanism.
