A new, affordable smart cane guides people with visual impairments safely and efficiently through their environments, say researchers.
Most know the white cane as a simple but crucial tool that assists people with visual impairments in making their way through the world.
Using tools from autonomous vehicles, the research team built the augmented cane, which helps people detect and identify obstacles, move easily around those objects, and follow routes both indoors and out.
The augmented cane is not the first smart cane.
Research sensor canes can be heavy and expensive—weighing up to 50 pounds with a cost of around $6,000. Currently available sensor canes are technologically limited, only detecting objects right in front of the user.
The new cane sports cutting-edge sensors, weighs only three pounds, can be built at home from off-the-shelf parts, and free, open-source software, and costs $400.
