Date of Original Version
Abstract or Description
Human wayfinding, both by sighted and visually impaired people, consists of two very different functions: 1. sensing of the immediate environment, including obstacles and physically defined paths, for the purposes of moving through it, and 2. navigating to remote destinations beyond the immediately perceptible environment.
