Wide Range Omni-Directional Intelligent Navigation System for the Visually Impaired

Compared to the non-visually impaired people, the visually impaired people have to face many challenges in everyday life. As per the report of World Health Organization (WHO), 80% of the vision impairment can be avoided out of 1.3 billion people who live with it worldwide. The risk of vision impairment can be the result of population growth and aging. To make their activities easier, assistive devices with updated technologies can support them for safe navigation, which will also increase and improve their functional capabilities. The age-old white cane and guide dog were used for their assistance but had their own hurdles. Thus, this research work has proposed a wide range of Omnidirectional smart assistive wearable device, which helps the visually impaired people to detect within the range of 2m and also notify the user through a buzzer sound at different time delays.
