Method and system for smart navigation for the visually impaired

摘要

In 2019, the World Health Organization stated that globally, approximately 2.2 billion people live with some form of vision impairment. Visual impairment limits the ability to perform everyday tasks and adversely affects the ability to interact with the surrounding world, thus discouraging individuals navigating unpredictable and unknown environments. The present invention is a method and a system to define and develop a smart navigation intelligent cane (i-Cane) that enables a visually impaired person to navigate his or her environment. The method and the system detects objects along the path of the visually impaired person, measures the distance of the objects from the person, identifies the objects, uses speech to alert the person of the approaching objects, the type of objects obstructing the path, and the distance between the objects and the person.
