Smart stick is an innovative stick designed for visually disabled people for improved navigation. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. A visually handicapped person has physical limitedness on the sense of vision. So to facilitate their mobility they typically use a cane. However, the cane contains a deficiency in terms of function. The deficiencies of the cane are that it cannot observe an out of range obstacle and blind’s family is unable to trace the blind’s location. Supported by these issues, we have developed a smart and innovative blind stick for a visually handicapped person using Raspberry Pi as a microprocessor and Arduino Uno as a microcontroller and it has sensors and buzzer to facilitate and provide help to its user as well as GPS and GSM as an added feature. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. On sensing obstacles the sensor passes this data to the microcontroller. The microcontroller then processes this data and calculates if the obstacle is close enough. If the obstacle is not that close the circuit does nothing. If the obstacle is close the microcontroller sends a signal and the vibrating motor starts vibrating. The vibrating motor is placed on the grip of the Smart blind stick to let the person sense the obstacle in front of him. The blind stick is integrated with two ultrasonic sensors that will help to detect the obstacles in front of the stick. The purpose of using two ultrasonic sensors is the difference of height of the obstacles. One sensor will be placed on the bottom of the stick and the other sensor will be placed in the middle of the stick. As a result, the smart blind stick will help the blind person to realize the exact nature of the obstacle in terms of its height. To help in tracking the location, this smart cane utilizes GPS to see the location and send it via SMS. This tactic utilized in this analysis is the design of hardware and software package, tool creating, and testing tool. The expected results of this research are to form a smart cane for a visually handicapped person which may assist their daily activities. A visually handicapped person will avoid a collision as a result of this smart cane as the stick can advise the person through the vibration motor and it may notify their family if they’re lost. The major objective of this project is to assist blind individuals to maneuver more freely by employing a reliable stick.
