Obstacle Sensing Assistance for Visually Impaired Person Using Arduino

Eyes plays a significant role in our everyday life. It is the most significant present for humans. This delightful world is noticeable to us since we are honored with visual perception. But some people unfortunately lag this ability to visualize the things. God has gifted them with other ability though helping those to see this world through the improved technology is our humanity. The visually challenged people face many challenges when moving in unfamiliar public places. To provide a smart and sensible navigation to them a smart walking stick can be designed which can be a great potential to them. The legally visually impaired individuals experience difficulty seeing things which others underestimate, similar to street signs, traffic signals, object before them, etc. They are more inclined to falls and different mishaps since they can’t clearly discern their surrounding environment. Many individuals with genuine visual disability can travel freely by using a wide scope of tools and techniques. The main portability aid utilized by them is a walking cane or walking stick. The traditional walking utilized by the outwardly tested individuals is really inefficient to detect the object in front of the user. Using the stick they can just distinguish the object that is being hit. A walking stick for the outwardly tested individuals utilizing a ultrasonic sensor and buzzer with Arduino Nano will become extraordinary assistance to them since this sort of walking stick can keep blind individuals from hit by an impediment open to question which can’t be recognized by the ordinary walking cane.The proposed device has many benefits like portable, efficient, low cost, futuristic, low power consumption and many more. The main purpose is to ensure the safety, security and usage convenience of the blind people and give them a device which makes them comfortable to walk.
