Humans interact and respond to conditions and circumstances around them based on what they see, hear, or smell from their environment. This is why it is important to maintain our senses and protect them from any harm or damage. Any damage we take will either eliminate our sensory organs or cause them to malfunction. Visually impaired people form a large portion of our society. Science and engineering branches are concerned for helping and improving their lives by designing many techniques that can provide them with their daily needs with minimal/no help from other people, which increases their independence and freedom. This design is not a fix but would help to take a step forward in making their life easier and can be a platform for a major breakthrough. The prototype differs from earlier prototypes that use infrared sensors alone, ultrasonic sensors alone, and infrared or ultrasonic sensors with GPS implemented with them. Each prototype has its advantages, disadvantages, materials, and working principle, as it is explained earlier in detail. But the combination of them would improve on the device. The battery in this prototype can be considered as the main disadvantage because it can die unexpectedly anywhere and anytime if it wasn't checked periodically by the user, his family, or caretaker. One of the ways this can be solved with is replacing the battery with solar cells, in any type, normal or bendable, but this will affect the complexity of the device, the whole cost of the device will also increase and this is the main reason they weren't used in the prototype. Voice navigation system can be used in the future to help the visually impaired in a better way and to give them more choices.
