Designing a flexible device to assist visually challenged people

Several people have slowly lost a vision over years; on the other hand some people are blind from birth. People who advise that the blind have a little vision and may be sensitive to light, May be blurred vision, and also having a limited field of vision like side vision, central vision or can see only half of the view. Some visually impaired peoples may not come out any different from other peoples; other people use cane. Visually impaired people find difficulty in identifying detail or in reading. However, when the output vision is affected it can decrease the visual area and hence the mobility a mobility difficult. By using Raspberry pi along with camera module a progressive work is done for developing an aid for visually impaired, which will help them in Reading, face Recognition, GPS location detection and controlling home appliances.
