Abstract
Navigating unfamiliar environments independently is a challenging task for people with visual impairments (PVIs). Navigation Assistive Technologies (NATs) enhance spatial cognition and independent navigation for PVIs through non-visual interaction. We look at an interactive navigational app (NavCog) that enables users to acquire spatial knowledge prior to navigation. Our main goal is to understand the application's ability to support independent, unassisted real-world navigation. We would like to understand whether building a mental sequential representation of a real-world path, prior to navigating a new location, is helpful for PVIs.
