In this paper, we present a wearable smart system to help visually impaired persons (VIPs) walk by themselves through the streets, navigate in public places, and seek assistance.The main components of the system are a microcontroller board, various sensors, cellular communication and GPS modules, and a solar panel.The system employs a set of sensors to track the path and alert the user of obstacles in front of Cart - Jinker them.The user is alerted by a sound emitted through a buzzer and by vibrations on the wrist, which is helpful when the user has hearing loss or is in a noisy environment.In addition, the system alerts people in the surroundings when the user stumbles over or requires assistance, and the alert, along with the system location, is sent as a phone message to registered mobile phones of family members and caregivers.
In addition, the registered phones can be used to retrieve the system location whenever required and activate real-time tracking of the VIP.We tested the system prototype and verified its functionality and effectiveness.The proposed system has more features than other similar systems.We Disposable Bowls expect it to be a useful tool to improve the quality of life of VIPs.
