The wearable distance meter design using sound waves high frequency for visual disabled people

The negatives that is encountered congenital or acquired disabled individuals need to be minimized in order to sustain the lives them. Obstacles should not be feel them throughout lifetime in order to accept that they are a part of a social structure. Therefore, technologies that will eliminate the restrictive side of the disabled is needed. This study basically detect the obstacles that is encountered blind, to facilitate the lives of the blind and it is simultaneously facilitate their wandering. Ultrasonic sensors detect it when blind encountered obstacles. Detected data send to microcontroller. Microcontroller send to center microcontroller using ZigBee transport protocol. Data that received different points is evaluated by center microcontroller. If blind is very close to obstacle, blind is warned by vibration motor and buzzer. Device was experimented over blind. To demonstrate the benefits of the developed device. Different type scenarios were produced for performed experiments and Obtained results were compared to each other. Developed device performance was found expected rate in performed comparison.
