Indoor envision system for the visually impaired

Student thesis: Master's Thesis

Abstract

This thesis presents a comprehensive assistive technology system, designed and implemented, to support the challenge faced by Visually Impaired (VI) individuals when they enter a new indoor environment. To design such a system, existing similar systems were first reviewed with their features and limitations. The identified limitations of the existing systems motivated the proposed work.The proposed system consists of a compact unit with a camera and accompanying sensors providing the Visually Impaired individual with a convenient and cost-effective solution, unlike the conventional method of using a white cane. The features are developed to ease visualization of the indoor environment for the Visually Impaired individuals and to make them independent of any external assistance in the visualization of the room. The proposed system was compared with similar existing systems. The evaluation was done by comparing accuracy results between the proposed system and existing systems. The proposed system was discussed with the people having visual impairments and was well appreciated. With a new overall system design and implementation, this thesis contributes to the fields of Electronic and Electrical Engineering,Digital Image Processing and Signal Processing.
