Globally blind and partially sighted people had the limited freedom to move forward alone outside of their residence due to some limitation of their supported guideline. But the time has been change and their supported guideline also improving day by day. In this paper proposed some logical technological idea which is implementable for making them more independence in outside environment. Two ultrasonic sensors will give the position (left or right) of the obstacle and LIDAR lite indicates them staircase and small height object through recognizable feedback through vibration motor and buzzer. Push button switch for SMS/call sending system help them to inform their family member in emergency situation. With the help of color sensor one specific line followed by them with predefine color will help them to go near buss top or shop which is very close to their house. For security issue a wireless door lock switch is placed on the stick. Identify their house door a color circle also recommended to fix in front of their house door. The main aim of this work is make their lifestyle smooth with the help of updated technology.
