There is an immense population of the visually impaired around the globe. Several research has been carried out to provide a technical aid to such people. The motivation of the system is to help blind people where they can move along without a dependent. Since there were existing on blind stick navigation, Akshi compose some unique features. Overall this research providing a solution for a blind person to move independently and securely with the use of as Raspberry Pi 2, HC-SR04 Ultrasonic Distance Measuring Transducer Sensor, 5V 2V Rechargeable Battery, GSM module, RFID Reader, RFID Tags. Some of the sub-problems that we faced during the course of our research were deciding on cost- effective and interoperable solutions, integrating the obstacle detection mechanism with location detection and implementing open source code and efficient coding techniques. An economically viable product which used open source was the key element to developing our prototype.
