ASSISTIVE APPLIANCE FOR BLIND PERSON By: Dwi Rachmad Zainuddin 7204 030 050

Electronic Engineering Politeknik Institute of Surabaya Institut Teknologi Sepuluh Nopember

BACKGROUND 



Lack of assistive appliance to less the difficulty of all blind people in their activity Desire to make an appliance exploit the AT89C51 with C Language

TARGET Design an assistive appliance for blind person to detect the barrier when walk

SCOPE AND LIMITATION Network system can only detect the object in front of this because the barrier will bounced radiation ultrasonic signal

EXPECTED RESULT AND RELEVANCY 



Expected result is microcontroller circuit attached in shoes can read the C Language program at Microcontroller AT89C51 so that shoes will inform the user if there is barrier in front of its Relevancy of result of this Final Project expected can be used by blind person to avoid barrier.
