An Artificial Eye for Blind People

The visually challenged people are always trying to lead their life comfortably with their surroundings. However, due to the loss of eyesight, their day-to-day life activities are greatly restricted. So it is necessary to find an easy way to make them familiar with an environment or routes in the world. The conventional walking sticks used by visually challenged people are not efficient for object detection. Those walking sticks are capable of detecting the stuff with which they collide. To overcome that difficulty, the authors developed an electronic assist as an intelligent stick using Raspberry Pi. This proposed stick offers artificial vision, object identification, and real-time GPS guidance for blind people. The proposed device senses an object in its vicinity and delivers voice information, alert signals via earphones, and navigation to a particular location via GPS. The ultimate objective of the intelligent stick is to offer a subtle amount and effective direction finding and obstruction detecting assist for the blind that provides a perception of imitation vision by supplying knowledge about the ecological situation of stationary and lively objects nearby them, allowing them to walk autonomously.
