Basic navigation of visually impaired people is a fundamental problem yet unsolved. Outdoor navigation is becoming a harder task for them in the increasingly complex urban world.
The technology and the solutions available for navigation of the blind are not sufficient and the size of the problem is huge with a large number of effected people.
India is considered as the Blind capital of the world. For instance, there are more than 3.2 crore Blind people in India alone, which is more than the total population of a small country like Nepal. Total number of visually impaired people requiring assistance in navigation is more than 7 crore in India.
40% of visually impaired people live in India alone. Globally the number of visually impaired people is 500M+
The current solutions used for the assistance in their navigation are not useful & effective, as most of them are hand-held, single sensor mount, difficult to hold devices, relying on vibrational & haptic feedback for notifying the user about any obstacle in their path.
Therefore, resulting in a lot of functional disadvantages of current solutions, for example- line of sight issues with hand held devices (stick needed to be kept straight at all times), manual alignment and lack of an intuitive feedback.
