The generally available blind stick are capable to finding obstacle that touch the stick physically, but here we propose an advanced blind stick that allows blind person to sense objects before stick touches them. Also it includes GPS tracking feature to find blind person and system allows the blind person to send out message with his GPS location to the caretaker or relatives in case of trouble or being lost.
