The blind and visually impaired people face many obstacles in moving and performing everyday tasks. To be able to move more safely blind people use assistive devices and tools for help.
The purpose of this diploma thesis of Stefana Hristovska is the design and realization of a simple obstacle detection system for the blind and visually impaired people that will assist them in their movement. The device is based on three ultrasonic sensors to detect obstacles. When an obstacle is detected, the user is alarmed via vibration. The device uses a power bank and has a potentiometer for adjusting the vibration intensity. The device weights 220 g (https://feit.ukim.edu.mk/en/computer-…).
The goal of this system is to help blind and visually impaired pedestrians by detecting and alarming them about obstacles that appear above the waist, up to the head. These obstacles cannot be detected using the white cane, which is the most commonly used device for movement assistance.
