  The ability to live without being controlled by any action, judgment and any
outside factors including any opinions and regulations is defined by the term
Independent. But in reality physical movement for travelling or simply walking
through a crowded street pose great challenge for a visually impaired person.
Also they must learn every detail about the home environment such as placement
of tables; chairs etc. to prevent injury. Because of this disability they have
to sacrifice their independence in daily living by depending on the sighted
people in every busy place like bus, footpaths, railway stations etc. This
paper aims to design an artificial navigating system with adjustable
sensitivity with the help of ultrasonic proximity sensor to assist these blind
persons to walk fearlessly and independently in both indoor and outdoor
environment. This system can detect any type of upcoming obstacles and potholes
using the reflection properties of ultrasound. Attachment of the system to
different body areas makes its utilization more versatile and reliable.
