Abstract: Now a day many visually impaired people face many problems when they walk on the roads or streets. These people need a device which is used in avoiding obstacle and helping in navigation. This paper introduces a novel embedded system device called voice enabled stick (VES) which is used to help the visually impaired people to navigate among the obstacles. This device is comprised of a long handle and three ultra-sonic sensors mounted at the end to extract the distance from the nearest obstacle. The output of the stick is in the form of voice to a head phone which gives commands to the user (visually impaired-person) to move right, turn left, and go straight or to stop. The user hears the voice commands from the device and navigates through the obstacles easily without any prior knowledge on the device. In this paper past existing devices have reviewed and the parameters related to these devices and VES are discussed. The improvement in different existing devices for blind people, their limitations and their advantages and disadvantages are examined. Comparison of different existing sticks with our proposed device is also recognized. Challenges issues and difficulties related to propose VES needs to be overcome have been highlighted. \textcopyright 2017 IEEE.
